[The practice guideline 'vitiligo']
[Article in Dutch]
Menke HE, van Everdingen JJ.
Sint Franciscus Gasthuis, afd. Dermatologie, Rotterdam.
A working group of the Dutch Society for Dermatology and Venereology (NVDV), in
collaboration with the Dutch Institute for Health Care Improvement (CBO), has
written an evidence-based guideline for the treatment of vitiligo. A distinction
is made between generalised or non-segmental vitiligo and localised, including
segmental, vitiligo. In patients with generalised vitiligo phototherapy
(especially narrow-band ultraviolet B) is the treatment of first choice while in
localised vitiligo, this is surgery, particularly autologous skin
transplantation (Thiersch grafting, the use of blister epidermis and cell
suspensions). However, on the basis of the results of the treatments proposed in
the guideline, the working group cannot advise dermatologists to propose a
particular treatment to each vitiligo patient they see. On the other hand, the
working group is of the opinion that, based on a proper medical examination and
an assessment of the disease burden, well-considered advice--and in some cases
therapy--should be given to every vitiligo patient who requests it. The benefit
of the guideline is that it provides clarity to dermatologists, general
practitioners and patients regarding the therapeutic possibilities and
limitations.

[Vitiligo—loss of cutaneous pigmentation]
[Article in Norwegian]
Sitek JC.
Hudavdelingen, Rikshospitalet-Radiumhospitalet, 0027 Oslo. jsitek@rikshospitalet.no
BACKGROUND: Vitiligo is an acquired pigmentary skin disorder that affects 0.5-2%
of the population. Many patients contact their physician and alternative
therapists for help. This review article presents an update of knowledge about
vitiligo and is aimed at physicians that treat this patient group. METHOD: The
article is based on literature identified on PubMed, textbooks in Dermatology
and supplemented by clinical experience. RESULTS AND INTERPRETATION: Vitiligo is
characterized by the absence of melanocytes in skin and hair follicles. The
pathogenesis is complex with genetic, autoimmune and toxic contributors.
Clinically well-defined milk-white maculae are seen in the skin, with a wide
variety of spread and distribution. The debut of vitiligo is often in childhood
and adolescence. Investigations indicate that vitiligo affects quality in life
for both children and adults. Treatment of vitiligo is a challenge. Phototherapy
with narrowband UVB or topical therapy with tacrolimus ointment or potent
steroids may be indicated in some cases, but the effect is not well documented.

[Long-term effects of PUVA therapy on Israeli patients with
vitiligo]
[Article in Hebrew]
Vussuki E, Ziv M, Rosenman D, David M.
Department of Dermatology, Rabin Medical Center, Petah Tikva, Israel. evusuki@clalit.org.il
BACKGROUND: Long-term treatment of psoriasis patients with PUVA (psoralen and
ultraviolet A) is associated with an increased risk of photoaging and non-melanomic
skin cancer, and perhaps of melanoma as well. Very little information is
available on the long-term effects of PUVA treatment on vitiligo patients in
general, and specifically on the risk of developing skin tumors. Among vitiligo
patients treated with PUVA or heliotherapy, only a few cases of squamous cell
carcinoma (SCC) have been described. OBJECTIVE: The objective of this research
is to examine the long-term effects of PUVA treatment among vitiligo patients
and the incidence of long-term side effects, including various types of skin
cancers. PATIENTS AND METHODS: The medical files of all patients treated with
PUVA at the Rabin Medical Center and the Emek Medical Center between 1982 and
1996 were surveyed. Each patient was interviewed by telephone and then invited
to come in for a medical examination. RESULTS: A total of 28 out of 31 patients
completed the questionnaire, and 12 of them were also examined. The average age
of the patients was 47 years (range 25-84). The average amount of radiation to
which each patient was exposed was 546.8 J/cm2 (range 26.5-1561), with a median
of 336.8 J/cm2. The average number of treatments per patient was 84.2 (median
77). The average time that elapsed since beginning the treatment was 11 years
(range 7-20), and the average time since treatment ended was 9.4 years (range
2-23). Partial or total repigmentation was experienced by 60% of the patients.
In 18% of the patients, total or almost total repigmentation was seen, which
lasted an average of 46 months. No skin cancer of any kind was seen in any of
the patients. CONCLUSION: A recurrence of the illness was seen in all the
vitiligo patients who had responded to PUVA treatment. Long-term treatment with
PUVA for vitiligo patients does not entail photoaging damages or increased risk
of skin cancer.

OBJECTIVE: The aim of this study was to study the effectiveness of the 308-nm
xenon chloride excimer laser in the treatment of vitiligo and to determine
factors that favor a good response to treatment. BACKGROUND DATA: Targeted
phototherapy using the 308-nm xenon chloride excimer laser represents an
effective therapy for the management of vitiligo. However, studies on a large
number of patients are few despite the increasing use of the excimer laser to
treat patients with vitiligo. METHODS: A retrospective chart review of 97
patients with chronic stable vitiligo was done with a total of 221 vitiligo
patches treated. RESULTS: Out of 221 vitiligo patches treated, 50.6% showed 75%
pigmentation or more, 25.5% achieved 100% pigmentation of their patches, and
64.3% showed 50% pigmentation or more. Lesions on the face responded better than
lesions elsewhere. CONCLUSION: The 308-nm xenon chloride excimer laser is an
effective and safe modality for the treatment of vitiligo, with good results
achieved in a relatively short duration of time.

Autologous melanocyte transfer via epidermal grafts for lip
vitiligo.
Gupta S, Goel A, Kanwar AJ, Kumar B.
>From the Department of Dermatology, Venereology, and Leprology, Postgraduate
Institute of Medical Education and Research, Chandigarh, India.
Background Vitiligo of the lips is a common concern of great psychologic
consequence. Medical therapies are often ineffective due mainly to the absence
of hair follicles. The transfer of melanocytes or melanocyte-bearing skin by a
surgical procedure may repigment this condition. Only a few surgical modalities
have been successful in this "difficult to treat" site. Objective To assess the
effectiveness of autologous melanocyte transfer by epidermal grafts for lip
vitiligo and to review the literature on the surgical correction of lip vitiligo.
Methods Twenty-six vitiligo patients (20 women and six men; age range, 13-43
years; mean, 26.8 years) having 31 affected lips with stable disease were
included in the study. The suction blisters were raised using our own modified
device on the lateral aspect of the thigh. The roofs of the blisters were
transferred to the dermabraded recipient area. The dressing, together with the
grafts, was removed on day 8. Patients were given photochemotherapy for 6 weeks.
In addition, meta-analysis of the published literature on the surgical
management of lip vitiligo was also performed. Results Complete repigmentation
was observed in 27 of the 31 lip areas (87%) in 23 of 25 patients (92%) in whom
a follow-up for 6 months or more was available. Complications observed were
persistent hyperpigmentation in 12 lips and reactivation of herpes in one
patient. Minimal hyperpigmentation was seen in most of the remaining lips. The
results of the meta-analysis revealed that the success rate varies from 32.5% to
100% with various surgical procedures. Conclusion Autologous melanocyte transfer
is an effective and safe therapeutic option for stable vitiligo of the lips. It
is cosmetically more acceptable, as there is no abnormal keratinization, which
is a problem associated with dermo-epidermal grafts.

Repigmentation of vitiligo with punch grafting and narrow-band
UV-B (311 nm)—a prospective study.
Lahiri K, Malakar S, Sarma N, Banerjee U.
>From the Pigmentary Disorder Unit, Rita Skin Foundation, Calcutta, India.
Background Phototherapy is already established as an effective mode of therapy
in vitiligo. An evidence-based study was carried out of the effect of
narrow-band (311 nm) ultraviolet-B (NB-UV-B) radiation in 66 surgically treated
patients with recalcitrant vitiligo in whom autologous mini-punch grafting was
deployed. Methods A total of 2613 grafts were placed over 108 lesions on 17
regions in 66 individuals (39 females and 27 males) with stable, refractory
vitiligo. The age range was 21-48 years. Postsurgically, they were exposed to a
suberythemal dose of NB-UV-B (311 nm). Different parameters of surgical
repigmentation were documented. Results Successful repigmentation was achieved
in 57 (86.36%) cases. The appearance of repigmentation (AOR) time in different
regions varied between 14 and 32 days, with an overall average of approximately
20.6 days. Maximum pigment spread (MPS) reached 12 mm with an average of 6.5 mm.
The relationship between the donor graft area and area of surgical
repigmentation was also calculated. Cobblestoning was the most common (31.8%)
complication, but improved with time and/or interference. Conclusions Punch
grafting in combination with phototherapy (NB-UV-B, 311 nm) was found to be an
easy, safe, inexpensive, and effective method of repigmenting static and
stubborn vitiligo. Different facets of punch grafting-induced and
phototherapy-aided surgical repigmentation were taken into consideration. The
area of repigmentation, MPS, and relationship between the donor graft area and
area of surgical repigmentation were documented.

Narrow-band ultraviolet B as monotherapy and in combination with
topical calcipotriol in the treatment of vitiligo.

Vitiligo is a common, idiopathic, acquired, depigmenting disease characterized
by loss of normal melanin pigments in the skin. The most interesting treatment
methods for extensive vitiligo involve psoralen plus ultraviolet A (PUVA)
therapy and ultraviolet (UV)-B phototherapy, particularly narrow-band UV-B. In
this randomized and comparative study, we investigated the safety and efficacy
of narrow band ultraviolet B as monotherapy and in combination with topical
calcipotriol in the treatment of generalized vitiligo. Of the 40 vitiligo
patients enrolled in the study, 15 were treated with the calcipotriol plus
narrow-band UV-B (NBUVB) and 25 with narrow band UV-B alone. The patients were
randomized into two NBUVB treatment groups. The first group, consisting of 24
patients (all male), received only NBUVB treatment; the second group, consisting
of 13 patients (all male) applied 0.05% topical calcipotriol ointments twice
daily. Both groups were irradiated with NBUVB (311 nm). In the NBUVB group, the
percentage of the body surface affected was reduced from 27.21 +/- 10.41% to
16.25 +/- 8.54% after a mean of 30 treatment sessions. The mean repigmentation
percentage was 41.6 +/- 19.4%. In clinical evaluation (moderate and
marked/complete response was accepted as an effective treatment), 19 patients
(19/24; 79.17%) had clinically good results. In the NBUVB plus calcipotriol
group, the percentage of the body surface affected was reduced from 23.35 +/-
6.5% to 13.23 +/- 7.05% after a mean of 30 treatment sessions. The mean
repigmentation percentage was 45.01 +/- 19.15%. In clinical evaluation (moderate
and marked/complete response was accepted as an effective treatment), 10
patients (10/13; 76.92%) had clinically good results. Statistically significant
intragroup reductions from the baseline percentage of the body surface affected
were seen at the endpoint of treatment for the two treatment groups (P < 0.001).
However, there was no statistically significant difference between the two
treatment groups at the end of therapy with respect to the reduction of
repigmentation rates (P > 0.05). The present study reconfirmed the efficacy of
NBUVB phototherapy in vitiligo. It can be a therapeutic option considered in the
management of patients with vitiligo. However, addition of topical calcipotriol
to NBUVB did not show any advantage.

BACKGROUND: The treatment with XeCl-excimer laser generated 308-nm UVB radiation
has shown promising results in patients with vitiligo. OBJECTIVE: In this
controlled, prospective trial we studied the primary efficacy (start and grade
of repigmentation) and patient's satisfaction of XeCl-excimer laser for
treatment of vitiligo patches at different body sites and re-evaluated the
achieved repigmentation 12 months after the end of therapy. METHODS: Twenty-five
patients with generalized or localized vitiligo with a total of 85 lesions at
different body sites were enrolled in this study. Vitiligo patches were treated
with 308-nm XeCl-excimer laser 3 times a week for 6 to 10 weeks. The overall
repigmentation grade of each treated lesion was evaluated once a week on a 5
point scale rating from 0 (no repigmentation), 1 (1-5%), 2 (6-25%), 3 (26-50%),
4 (51-75%), to 5 (76-100%). RESULTS: Twenty-four patients completed the study.
Within 6 to 10 weeks of treatment 67% of the patients (16/24) developed
follicular repigmentation of at least one of their vitiligo lesions. Lesion
repigmentation started after a mean of 13 treatments in lesions located on the
face, trunk, arm, and/or leg (high-responder location), and after a mean of 22
treatments in lesions located on the elbow, wrist, dorsum of the hand, knee,
and/or dorsum of the foot (low-responder location). Untreated control lesions
and lesions located on the fingers did not achieve any repigmentation. After 10
weeks of treatment repigmentation of more than 75% was found in 25% (7/28) of
lesions of the high-responder location group versus 2% (1/43) of lesions of the
low-responder location group. In most cases, laser-induced repigmentation was
persistent, as determined 12 months after the end of treatment. CONCLUSIONS:
308-nm excimer laser is an effective modality for the treatment of vitiligo.
However, similar to other non-surgical treatment modalities, the therapeutic
effect is mainly dependent on the location of vitiligo lesions.

Dermatosurgical techniques for repigmentation of vitiligo.
Rusfianti M, Wirohadidjodjo YW.
Dermatovenereology Department, School of Medicine, Gadjah Mada University,
Sardjito Hospital, Yogyakarta, Indonesia.
There are a number of dermatosurgery techniques available to achieve
repigmentation of vitiligo, such as suction blister grafting, split-thickness
skin grafting, punch grafting, follicular grafting, cultured-melanocytes
transplantation, and noncultured-melanocytes transplantation. Each method has
advantages and disadvantages. As there are no specific data available from the
prospective studies in this field it is uneasy to recommend which surgical
approach to vitiligo offers the best result. According to a systematic review by
Njoo et al.,(17) suction blister and split-thickness skin grafting have the
highest rates of success (87%), while the average success rates for other
methods varied from 13% to 53%. Punch grafting has the highest rate of adverse
effects, including cobblestoning appearance (27%) and scar formation (40%) in
the donor site. Accordingly, it is also mandatory to appropriately select
vitiligo patients in order to achieve a complete and permanent repigmentation.

Effect of topical calcipotriol, betamethasone dipropionate
and their combination in the treatment of localized vitiligo.
Kumaran M, Kaur I, Kumar B.
Department of Dermatology, Venereology and Leprology, Postgraduate Institute
of Medical Education and Research, Chandigarh, India.
Background Treatment of vitiligo is a challenge. Steroids are known to be
effective but are associated with serious adverse effects. Many uncontrolled
studies have shown calcipotriol to be a promising therapeutic modality in
vitiligo. Objective To conduct a randomized trial to evaluate the effect of
topical calcipotriol ointment (0.005%) and betamethasone dipropionate
(0.05%) cream, given alone or in combination, in treatment of localized
vitiligo. Methods Forty-nine patients with vitiligo affecting 5% of their
skin were recruited. Patients were randomized into three groups. Group I
patients were treated with betamethasone dipropionate (0.05%) cream twice
daily. Group II patients were treated with calcipotriol ointment (0.005%)
twice daily, and group III with betamethasone dipropionate (0.05%) in the
morning and calcipotriol (0.005%) in the evening. Results Forty-five
patients completed the study period of 3 months with 15 patients in each
group. No patient achieved excellent (> 75%) pigmentation. Marked (50% to
75%) repigmentation was observed in 2 (13.3%), 1 (6.7%) and 4 (26.7%)
patients in groups I, II and III, respectively. Moderate (25-50%)
repigmentation was observed in 7 (46.7%), 5 (33.3%) and 7 (46.7%) patients
in groups I, II and III, respectively. Patients with < 25% pigmentation were
termed as minimal pigmentation or no response. The mean time for initial
pigmentation to appear was 9.04 +/- 2.0 weeks in group I, 10.18 +/- 1.6
weeks in group II and 5.17 +/- 2.4 weeks in group III (P < 0.01). The
acquired pigmentation in the lesions was more stable in group III as
compared with patients in groups II and I (P < 0.01). Side-effects in the
form of atrophy and lesional burning sensations were more common in group I
when compared with groups II and III (P < 0.05). Conclusion Combined therapy
appeared to give a significantly faster onset of repigmentation along with
better stability of the achieved pigmentation and with lesser number of
side-effects.

Tacalcitol and narrow-band phototherapy in patients with
vitiligo.
Leone G, Pacifico A, Iacovelli P, Vidolin AP, Picardo M.
Phototherapy Unit, S. Gallicano Dermatological Institute, IRCCS, Rome,
Italy.
Background. Vitiligo is a skin disease characterized by loss of normal
pigmentation in the skin. Several treatments exist but none is really
effective. Recently, perturbations of calcium homeostasis in vitiliginous
epidermis have been described. Aim. Based on these findings, the aim of this
prospective, randomized, open-label study was to compare the effectiveness
of narrow-band ultraviolet B (NB-UVB) phototherapy alone and the combination
of NB-UVB and topical application of the vitamin D(3) analogue tacalcitol in
the treatment of vitiligo. Methods. In total, 32 subjects with generalized
vitiligo and symmetrical lesions were enrolled in the study. Subjects were
instructed to apply tacalcitol ointment daily to the lesion on the side
randomly selected to receive combination therapy. All subjects received NB-UVB
phototherapy on a twice-weekly schedule. Results. Addition of topical
tacalcitol to NB-UVB treatment improved the extent of repigmentation and
increased the response rate in patients with vitiligo compared with NB-UVB
treatment alone. Conclusion. Application of tacalcitol ointment in
combination with twice-weekly NB-UVB phototherapy is an effective
alternative treatment for patients with generalized vitiligo.

Topical macrolide immunomodulators : a role in the treatment
of vitiligo?
Tjioe M, Vissers WH, Gerritsen MJ.
Department of Dermatology, Radboud University, Nijmegen Medical Centre,
Nijmegen, The Netherlands.
Recently, topical macrolide immunomodulators have been successfully
introduced in the treatment of atopic dermatitis. With the growing interest
in this new line of topical immunosuppressants, research into the efficacy
of these medicines in other T-cell-mediated skin diseases, such as
psoriasis, lichen planus, and even vitiligo, is expanding rapidly. It is
generally accepted that autoimmune factors play an important role in
vitiligo. In this article, the possible use and mechanism of topical
macrolide immunomodulators in the treatment of vitiligo are discussed,
together with the current state of clinical studies and case reports. These
limited reports indicate that topical macrolide immunomodulators may play a
role in the treatment of vitiligo, particularly in areas where use of potent
corticosteroids is contraindicated.

Psoralen-ultraviolet A vs. narrow-band ultraviolet B
phototherapy for the treatment of vitiligo.
Parsad D, Kanwar AJ, Kumar B.
Department of Dermatology, Venereology and Leprology, Postgraduate Institute
of Medical Education & Research, Chandigarh, India.
Background Although many treatment modalities have been tried for the
treatment of vitiligo, none is uniformly effective. Psoralen phototherapy (psoralen
ultraviolet A (PUVA)) is established as efficacious treatment for vitiligo.
Recently, narrow-band UVB (NBUVB) has been reported to be an effective and
safe therapeutic option in patients with vitiligo. Objective To compare the
efficacy of PUVA and NBUVB in the treatment of vitiligo. Design and setting
Retrospective analysis of 69 patients with vitiligo who were treated either
with PUVA or NBUVB at the pigmentary clinic of the Dermatology Department of
the Postgraduate Institute of Medical Education and Research, Chandigarh,
India. Outcome measures The following variables were compared between the
two groups of patients: repigmentation status, number of treatments for
marked to complete repigmentation in existing lesions, appearance of new
lesions or increase in size of existing lesions, adverse effect of therapy,
stability of repigmentation and colour match. Results In PUVA-treated group,
9 patients showed marked to complete repigmentation (23.6%) and 14 patients
showed moderate improvement (36.8%), whereas in NBUVB-treated group, 13
patients showed marked to complete repigmentation (41.9%) and 10 patients
showed moderate improvement (32.2%). A statistically significantly better
stability and colour match of repigmentation with surrounding skin was seen
in NBUVB-treated patients. Conclusion We showed that NBUVB is more effective
than PUVA and repigmentation induced with NBUVB is statistically
significantly more stable.

Use of the 308-nm excimer laser for psoriasis and vitiligo.
Passeron T, Ortonne JP.
Department of Dermatology. Archet 2 Hospital, 06202 NICE Cedex 3, France.
The 308-nm excimer laser represents the latest advance in the concept of
selective phototherapy. It emits a wavelength in the UV-B spectrum and thus
shares the same indications as conventional phototherapy. Like other laser
devices, the 308-nm excimer laser emits a monochromatic and coherent beam of
light, can selectively treat a lesion while sparing surrounding healthy
skin, and can deliver high fluencies. Clinicians have taken advantage of
these properties to treat dermatologic disorders since 1997, with psoriasis
and vitiligo attracting most attention. Initially, high fluencies (minimal
erythemal dose, 8-16) were used, with excellent clinical results, to treat
psoriasis vulgaris. The significance of side effects and the potential
long-term carcinogenic risk associated with such fluencies have resulted in
medium doses (about 3 minimal erythemal dose) being recommended, however.
Interestingly, taking advantage of the selectivity of the laser, newer
treatment protocols adapt the dose to the lesion and not to the minimal
erythemal dose, as is the case for conventional phototherapies. Many
prospective study series have also shown the efficacy and the good tolerance
of the 308-nm excimer laser in the treatment of localized vitiligo. Induced
rates of repigmentation seem to be higher than with narrowband UV-B.
Moreover, the selectivity of the treatment prevents irradiation of healthy
skin and limits unsightly tanning of surrounding skin. Aesthetically
pleasing results are usually not achieved in extremities and bony
prominences, which are not good indications for this technique. Combining
the 308-nm excimer laser with 0.1% tacrolimus ointment has provided very
interesting results, which need to be confirmed in larger series. The
absence of actual data concerning the long-term risk for skin cancer after
this treatment means that it should be considered with caution. Combination
with topical steroids appears to be synergistic and potentially reduces
long-term side effects; again, prospective data are lacking.

Interventions for vitiligo.
Whitton M, Ashcroft D, Barrett CW, Gonzalez U.
BACKGROUND: Around 1% of the world's population has vitiligo, which causes a
loss of skin colour in patches. The methods currently available to treat
vitiligo are largely unsatisfactory and vary widely between cultures and
within health systems. OBJECTIVES: To assess the effects of interventions
used to manage vitiligo. SEARCH STRATEGY: We searched the Cochrane Skin
Group Specialised Register, the Cochrane Central Register of Controlled
Trials, MEDLINE, EMBASE, AMED and other databases (last searched September
2004). Reference lists of articles and conference proceedings were searched.
Authors of reviews were contacted. SELECTION CRITERIA: Randomised controlled
trials (RCTs). DATA COLLECTION AND ANALYSIS: At least two reviewers
independently assessed study eligibility and methodological quality and
carried out data extraction. The included studies compared different
interventions and used different outcome measures so we considered it
inappropriate to combine their results. MAIN RESULTS: Nineteen trials with a
total of 1350 participants were included. The RCTs generally had low numbers
of participants and only RCTs of repigmentation and not other methods of
managing vitiligo were able to be included.In one study, potent topical
steroids resulted in better repigmentation than placebo and they were also
better than oral psoralens plus sunlight in another study (RR 4.70 95% CI
1.14 to 19.39) although their long-term use is limited by adverse effects.
Two studies suggested that topical calcipotriol enhanced repigmentation
rates from PUVAsol and PUVA when compared with placebo. Another two studies
showed higher repigmentation rates with oral PUVAsol versus placebo plus
sunlight (RR 19.20 95% CI 1.21 to 304.50 in 79 adults and RR 2.29 95% CI
1.14 to 4.58 in a study of 50 children). The safety of these interventions
was poorly described and none of the studies was able to demonstrate long
term benefits. Very few studies were carried out on children or included
segmental vitiligo. No trials evaluating micropigmentation, melanocyte
transplantation, depigmentation or cosmetic camouflage could be found.
Despite the fact that the main impact of vitiligo is psychosocial only one
study on psychological therapy was found and it is awaiting assessment.
AUTHORS' CONCLUSIONS: This review has found some evidence to support
existing therapies for vitiligo, but the different designs and outcome
measurements, lack of quality of life measures and adverse effect reporting
in the studies limit the usefulness of their findings. There is a pressing
need for high quality randomised trials using standardised measures of
repigmentation and which address relevant clinical outcomes including
quality of life.

Treatment of vitiligo with broadband ultraviolet B and
vitamins.
Don P, Iuga A, Dacko A, Hardick K.
Department of Dermatology, Metropolitan Hospital Campus of New York Medical
College, NY, USA.
BACKGROUND: While oral psoralen plus ultraviolet A (PUVA) remains the most
popular therapeutic modality for vitiligo, recent reports have shown that
narrowband ultraviolet B (UVB) also induces significant repigmentation. In
this study we evaluated the efficacy of broadband UVB on actively spreading,
progressive vitiligo in patients who had been followed for many months (12
or more) in our practice, who continued to depigment despite treatment.
METHODS: Nine patients with actively spreading vitiligo were exposed to
broadband UVB 2-3 times per week at a starting dose of 20-30 mJ/cm(2).
Radiation was increased by 10-20 mJ/cm(2) per session with adjustments for
symptomatic erythema or missed visits. In addition, patients took vitamin C
500 mg twice a day (BID), vitamin B(12) 1000 microg BID and folic acid 5 mg
BID. The response to treatment and side-effects were assessed at each visit.
The patient's response to treatment and progress were assessed by
photographs and by physician evaluation of body surface area (BSA) (using
the Rule of 9s) involved at monthly intervals. Photographs were taken and
estimations of BSA by physical examination made at the start and finish of
the trial and then compared by the physicians involved in the study.
RESULTS: Broadband UVB halted the progression of vitiligo in all nine
patients and in general induced repigmentation early after 8-12 treatments
(6-8 weeks). After 2-8 months of treatment, nine of nine patients achieved
good (51-75%) or excellent response (76-100%). The percentage of
repigmentation varied with length of treatment and anatomic site.
CONCLUSIONS: This study confirms the only published report that broadband
UVB is effective on actively spreading vitiligo. Since it is more cost
effective than narrowband UVB and has numerous advantages compared to oral
PUVA, broadband UVB may offer an alternative for future treatment of
vitiligo. The role of vitamins in this therapy remains to be determined.

BACKGROUND: Replenishing melanocytes selectively in vitiliginous macules by
autologous melanocytes is a promising treatment. With expertise in culturing
melanocytes, it has now become possible to treat larger recipient areas with
smaller skin samples. AIM: To study the extent of repigmentation after
autologous melanocyte transplantation in patients with stable vitiligo.
METHODS: The melanocytes were harvested as an autologous melanocyte rich
cell suspension from a donor split thickness graft. Melanocyte culture was
performed in selected cases where the melanocyte cell count was insufficient
to meet the requirement of the recipient area. These cells were then
transplanted to the recipient area that had been superficially dermabraded.
RESULTS: An excellent response was seen in 52.17% cases with the autologous
melanocyte rich cell suspension (AMRCS) technique and in 50% with the
melanocyte culture (MC) technique. CONCLUSION: Autologous melanocyte
transplantation can be an effective form of surgical treatment in stable but
recalcitrant lesions of vitiligo.

Phenytoin as a novel anti-vitiligo weapon.
Namazi MR.
Vitiligo is a psychologically devastating clinical conundrum which affects
approximately 1% of the general population. The exact cause of the illness
is an enigma, but several hypotheses about its pathogenesis are advanced.
The autoimmune hypothesis proposes an autoimmune attack against melanocytes.
Although anti-melanocyte autoantibodies have been demonstrated in vitiligo,
recent research casts doubt on their pathogenic role and instead supports
the involvement of cell-mediated autoimmune response in the pathobiology of
this disorder, which is characterized by increase of suppressor T-cells and
decrease of the helper/suppressor ratio in association with the presence of
type-1 cytokine secreting cytotoxic T cells in the vicinity of disappearing
melanocytes, The neural hypothesis proposes that increased release of
norepinephrine, a melanocytotoxin, from the autonomic nerve endings in the
microenvironment of melanocytes injures these cells. Moreover,
norepinephrine induces the catecholamine degrading enzyme monoamine oxidase
(MAO), which favors the formation of toxic levels of hydrogen peroxide in
the vicinity of melanocytes. Another theory suggests that abnormal
permeability of melanosome membrane, which normally prevents the diffusion
of toxic melanin precursors into the cytoplasm, may cause melanocyte damage.
Phenytoin, the widely-used anticonvulsant, has been employed both topically
and systemically in the treatment of some dermatological disorders. The drug
has been shown to significantly suppress mitogen-induced activation of
lymphocytes and cytotoxic T lymphocyte activity and to polarize the immune
response toward the type-2 pathway. It also significantly decreases
suppressor T cells and increases the helper/suppressor ratio. At high
concentrations, the drug inhibits the release of norepinephrine and the
activity of MAO. Moreover, phenytoin is suggested to interact with membrane
lipids, which may promote stabilization of the membranes. The hydantoin
moiety of phenytoin exerts a direct stimulatory action on melanocytes;
facial hyperpigmentation is a recognized side effect of orally administered
phenytoin. Altogether, the above evidence suggests that phenytoin could be
therapeutically effective against vitiligo. As phenytoin stimulates collagen
production and inhibits its breakdown, its concomitant use with topical
steroids could prevent steroid-induced skin atrophy while potentiating the
anti-vitiligo effect of these agents.

Phototherapy with ultraviolet (UV) irradiation of wavelengths between 280
and 320 nm (UV-B) is a safe and effective treatment for a variety of
inflammatory skin diseases. In addition to standard broad band UVB, narrow
band phototherapy with fluorescent bulbs emitting near monochromatic UV
between 310-315 nm has become an important treatment for diseases such as
psoriasis, atopic dermatitis or vitiligo. Other diseases respond favorably
to narrow band UV-B phototherapy, the number of potential indications for
such phototherapy is continuously growing. The differential effects of
narrow band UV-B phototherapy in comparison to other UV phototherapies, as
well as new and established indications for this treatment modality are
reviewed.

Long-term follow-up study of 142 patients with vitiligo
vulgaris treated by autologous, non-cultured melanocyte-keratinocyte cell
transplantation.
Mulekar SV.
Noble Clinic: Pune - India. dr_mulekar@vsnl.com
BACKGROUND: Vitiligo vulgaris patients are difficult to treat surgically
owing to large area involvement. Larger areas can be treated with the help
of in vitro cultured melanocytes. These techniques are complex. In most of
the studies published to date the number of patients reported is low and
follow-up period short. OBJECTIVE: To evaluate long-term efficacy and safety
of melanocyte-keratinocyte cell transplantation in large number of vitiligo
vulgaris patients. METHODS: A simpler and modified method based on that of
Olsson and Juhlin has been used. It uses shave biopsy skin sample up to
1/10th the size of recipient area. Skin sample is incubated, cells
mechanically separated using trypsin-EDTA solution, and then centrifuged to
prepare a suspension. Cell suspension is then applied to a dermabraded
de-pigmented skin area and collagen dressing given to keep it in place.
RESULTS: One hundred and forty-two patients with vitiligo vulgaris were
treated and observed for a period up to 6 years. Eighty (56%) patients
showed excellent, 15 (11%) showed good, 13 (9%) showed fair and 34 (24%)
showed poor repigmentation, which was retained till the end of the
respective follow-up period.

BACKGROUND: Vitiligo therapy is difficult. Depending on its clinical
presentation, unilateral or bilateral vitiligo lesions respond well with
different repigmentation rates, according to age, affected anatomic area,
extension of lesions, time at onset, timing of depigmentation spread, and
other associated factors. When stable and refractory to medical treatment,
vitiligo lesions may be treated by implanting pigment cells on depigmented
areas. OBJECTIVE: To describe the main events of depigmentation and the
fundamentals of surgical techniques for repigmenting vitiligo by implanting
noncultured cellular or tissue grafts, in vitro cultured epidermis-bearing
pigment cells, or melanocyte suspensions. METHODS: A description of the
available techniques for repigmentation of vitiligo is done, emphasizing the
most important details of each procedure to obtain the best repigmentation
and minimize side effects. RESULTS: With most of these techniques, adequate
repigmentation is obtained, although there are limitations when applying
some methods to clinical practice. CONCLUSIONS: Restoration of pigmentation
may be accomplished with all available surgical procedures in most anatomic
locations, but they are of little value for acral areas. Unilateral vitiligo
responds well in a high proportion of patients, and bilateral disease may
also respond when stable. Appropriate patient selection is important to
achieve the best results.

Narrow-band UVB vs. broad-band UVB therapy in combination
with topical calcipotriol vs. placebo in vitiligo.
Hartmann A, Lurz C, Hamm H, Brocker EB, Hofmann UB.
>From the Department of Dermatology, University of Wurzburg, Germany.
Background Recently, it has been shown that UVB phototherapy may be more
effective than UVA in the treatment of vitiligo. Currently, however, no
studies have compared the efficacy of UVB(311 nm) and broad-band UVB
therapy. Calcipotriol has recently been reported to be effective adjunctive
treatment for vitiligo, enhancing the efficacy of 8-methoxypsoralen plus UVA
(PUVA) therapy. Methods Ten patients were enrolled in the study; nine
completed the 12 months of therapy. The upper part of the body was treated
twice weekly with UVB(311 nm) and the lower part with broad-band UVB.
Calcipotriol was applied onto the vitiligo lesions of the right side of the
body and placebo on the left side. Repigmentation was documented by
photography, planimetry, and Vitiligo Disease Activity (VIDA) score. The
quality of life was measured by the Dermatology Life Quality Index (DLQI).
Results After 7-16 weeks, six of the nine patients showed initial
repigmentation on the side treated with UVB(311 nm). After 6 months of
treatment, none of the patients showed repigmentation on the areas treated
with broad-band UVB, which prompted us to apply UVB(311 nm) all over the
body. At the end of 12 months, two patients showed > 75% repigmentation, two
showed 51-75%, two showed 26-50%, and three showed 0-25%. In all patients
with progressive vitiligo (seven of the nine patients), disease activity was
stopped. Remarkably, vitiligo lesions treated with calcipotriol initially
showed delayed repigmentation compared with control areas; however, there
was no therapeutic difference between calcipotriol and placebo, both in
combination with UVB(311 nm), by the end of the study. The DLQI score
improved significantly by an average of 28%. Conclusion UVB(311 nm) therapy
was effective in the treatment of vitiligo, whereas broad-band UVB had no
effect. Combination with calcipotriol ointment was not superior to UVB(311
nm) monotherapy. The quality of life significantly improved with narrow-band
UVB(311 nm) phototherapy.

Micropigmentation: tattooing for medical purposes.
Garg G, Thami GP.
Department of Dermatology and Venerology, Government Medical College and
Hospital, Chandigarh, India.
BACKGROUND: Micropigmentation, also known widely as tattooing, is being
commonly used esthetically to camouflage various medical conditions related
to dermatology and plastic surgery. OBJECTIVE: The aim was to review the
procedure of tattooing and its various latest medical indications. METHODS:
Peer review of the literature on micropigmentation through a MEDLINE search
was done to enumerate its various medical indications. RESULTS: The
literature review revealed widespread acceptance of micropigmentation for a
spectrum of diseases of cosmetic importance, especially in mucosal vitiligo.
Micropigmentation is also being used for various medical indications, such
as burn scars, alopecia areata, and nipple-areola reconstruction.
CONCLUSIONS: The procedure is relatively easy, provides permanent
camouflage, and is generally devoid of any significant adverse effects.
However, a number of infections can be transmitted from one patient to
another if the universal precautions for sterilization of instruments used
for micropigmentation are not adhered to.

Autografts and cultured epidermis in the treatment of
vitiligo.
Pianigiani E, Andreassi A, Andreassi L.
Department of Dermatologic Sciences, University of Siena, Policlinico Le
Scotte, 53100 Siena, Italy.
Skin transplants can be a useful and efficacious method to treat vitiligo.
The aim is to repopulate areas lacking melanocytes with functional cells
taken from normally pigmented areas. Several procedures have been devised
and tested: some consist in the simple transfer of epidermis sampled and
implanted as is, whereas others are based on the transplantation of
disaggregated and manipulated cells. The therapeutic success of the former
methods is partly determined by the ability and experience of the surgeon
performing the operation, whereas the results of the latter methods mainly
depend on the laboratory facilities and abilities of the personnel who
manipulate the cells to be transplanted. The transplantation of cultured
cells is the most fascinating and promising procedure but requires the
observance of still not completely predictable procedures. The use of
biological material of animal origin and the use of factors to stimulate
cell proliferation, such as growth factors and promoting agents, are other
points that require attention.

A randomized placebo-controlled double-blind study of
levamisole in the treatment of limited and slowly spreading vitiligo.
Agarwal S, Ramam M, Sharma VK, Khandpur S, Pal H, Pandey RM.
Department of Psychiatry, All India Institute of Medical Sciences, New Delhi
110 029, India.
BACKGROUND: A previous uncontrolled, open trial of levamisole in patients
with limited and slowly spreading vitiligo had shown that new lesions did
not develop in 94% of patients after 2-4 months of treatment with the drug.
OBJECTIVES: To assess the efficacy of levamisole in the treatment of slowly
spreading, limited vitiligo. METHODS: In a randomized double-blind trial at
the Department of Dermatology and Venereology, All India Institute of
Medical Sciences, New Delhi, India, 60 patients with vitiligo involving < 2%
of the body surface area and with slowly spreading disease (defined as one
to five new lesions in the previous month or six to 15 new lesions in the
previous 3 months) were randomly allocated to receive oral levamisole 150 mg
or placebo on two consecutive days in a week. Children received oral
levamisole 100 mg. All patients applied mometasone furoate 0.1% cream on the
depigmented macules once daily. Patients were evaluated monthly for 6
months. The main outcome measure was the occurrence of new lesions, counted
at each monthly visit. The secondary outcome measures comprised: (i) a
dermatology-specific instrument, the Dermatology Life Quality Index or
Children's Dermatology Life Quality Index questionnaires, which were
completed by the patients at baseline and at every visit, and (ii) a general
health questionnaire, the World Health Organization Quality of Life Brief
Questionnaire, which was completed at baseline and at the end of the study.
RESULTS: Forty-three patients completed 6 months of follow-up. The mean +/-
SD number of new lesions that developed during the study period of 6 months
was 1.9 +/- 2.0 (range 0-8) in the levamisole group and 1.8 +/- 2.0 (range
0-7) in the placebo group (P = 0.92). The proportion of patients who did not
develop any further new lesions for the remainder of the study period was
higher in the levamisole group at all the monthly evaluation points,
although it was statistically significant (P = 0.05) only at the fourth
month. Improvement in quality of life was similar in both groups.
CONCLUSIONS: The study indicates that levamisole is not as effective in
arresting disease progression as was observed in a previous open study. A
study with a larger sample size is necessary to determine if levamisole is
truly superior to placebo in this respect.

Narrow-band UVB for the treatment of generalized vitiligo in
children.
Kanwar AJ, Dogra S.
Department of Dermatology, Venereology and Leprology, Postgraduate Institute
of Medical Education and Research, Chandigarh, India. ajkanwar@sify.com
Vitiligo usually begins in childhood with approximately half of the patients
manifesting onset of disease prior to the age of 20 years. Treatment options
in this age group are few and have disappointing response rates. This study
was designed to evaluate the role of narrow-band UVB in the treatment of
generalized vitiligo in children. Twenty-six children (aged 5-14 years) with
generalized vitiligo (minimal extent of depigmentation of 5% of the skin)
were treated three times per week with narrow-band UVB therapy for a maximum
period of 1 year. Of 26 patients, 6 were lost to follow up and 20 (7 males,
13 females) completed the study. At the end of 1 year of therapy, 15 (75%)
patients developed marked to complete repigmentation. Moderate and mild
repigmentation was noted in four (20%) and one (5%) patients, respectively.
An average number of 34 (+/- 2) treatment visits was required to achieve 50%
repigmentation. Adverse events were mild and transient. Narrow-band UVB is
an effective and well-tolerated treatment option for childhood vitiligo.

We report our experience with UV-B narrowband (UV-B-NB) therapy in children
affected by vitiligo. We studied 10 Caucasian Italian children (six boys,
four girls, mean age 9.7 years +/- 2.67). Treatment mean term was 5.6
months; frequency was three times a week on nonconsecutive days or only
twice a week, because of school or family duties. The percentage of
repigmentation was evaluated by comparing photographs taken before, during,
and after the treatment, and showed a repigmentation level higher than 75%
in five patients (5/10, 50%) and between 26% and 75% in three patients
(3/10, 30%). Of our patients, 80% had a satisfactory response to
phototherapy. Adverse events were limited and transient. No significant
relationships between repigmentation grades and variables such as skin type,
positive family history, and disease extension were observed. Some areas
responded better than others; the best results were shown on the face and
neck. Perhaps we studied too few patients to be conclusive, but the results
obtained so far seem to indicate that children affected by recent vitiligo
have a better response to the therapy. We feel that UV-B-NB therapy is a
valuable and safe option for the treatment of pediatric vitiligo, and should
be started as soon as possible.

Optimal weekly frequency of 308-nm excimer laser treatment in
vitiligo patients.

Department of Photodermatology, Medical University Graz, Auenbruggerplatz 8,
A-8036 Graz, Austria.
Summary Background Recently the beneficial effect of excimer laser treatment
has been reported for patients with vitiligo. The influence of treatment
frequency on this effect is not clear. Objectives To determine the optimal
frequency of 308-nm excimer laser therapy for vitiligo. Methods In this
prospective, university-based hospital study over 12 weeks we enrolled 14
patients. Each had at least three stable vitiligo lesions in the same body
area. The three stable vitiligo lesions in each subject were randomly
assigned to receive excimer laser treatment once (1 x), twice (2 x) and
three times (3 x) weekly, respectively. The initial ultraviolet (UV) dose
was 50 mJ cm(-2) less than the 308-nm minimal erythematous dose in vitiligo
skin. The UV dose was increased at each treatment session according to the
erythematous response to the previous treatment. Results Thirteen subjects
were treated for at least 6 weeks; seven were treated for all 12 weeks. At 6
weeks, the repigmentation rates for treated lesions were 8% (1/13) after 1 x
weekly treatment, 23% (3/13) after 2 x weekly treatment and 62% (8/13) after
3 x weekly treatment (P = 0.0134; 3 x vs. 1 x weekly); at 12 weeks, these
rates were 46% (6/13), 62% (8/13) and 69% (9/13), respectively (P = NS; 3 x
vs. 1 x weekly). Repigmentation initiation correlated with treatment number,
regardless of frequency (P = NS). As shown by Kaplan-Meier analysis,
repigmentation occurred earliest in the most frequently treated lesions (P =
0.0336). At 12 weeks, the projected repigmentation rates for 1 x, 2 x and 3
x weekly treatment approached each other (60%, 79% and 82%, respectively);
the mean repigmentation grades (on a scale of 0-5) for 1 x, 2 x and 3 x
weekly treatment were 1.7, 2.4 and 3.3, respectively (P = 0.018; 3 x vs. 1 x
weekly). Laser-induced repigmentation persisted in most cases over the
entire follow-up of 12 months after the end of treatment. Conclusions 308-nm
excimer laser therapy is effective against vitiligo. Although repigmentation
occurs fastest with 3 x weekly treatment, the ultimate repigmentation
initiation seems to depend entirely on the total number of treatments, not
their frequency. However, treatment periods of more than 12 weeks may be
necessary to obtain a satisfactory clinical repigmentation, particularly
when vitiligo lesions are treated only 1 x or 2 x compared with 3 x weekly.

Comparison of Minipunch grafting versus split-skin grafting
in chronic stable vitiligo.
Khandpur S, Sharma VK, Manchanda Y.
Department of Dermatology and Venereology, All India Institute of Medical
Sciences, New Delhi, India. shaifalikhandpur@eth.net
BACKGROUND: Minipunch grafting (MPG) and split-skin grafting (SSG) are
common outpatient procedures for the surgical treatment of chronic stable
vitiligo. However, there is a paucity of literature comparing the two
procedures by the same group of investigators. OBJECTIVE: To compare the two
techniques in patients with chronic stable localized vitiligo. METHODS:
Sixty-four patients with stable vitiligo of 6 months duration were
randomized into two groups to be taken up for MPG or SSG in a representative
patch followed by PUVAsol therapy for 3 months. They were evaluated 3 months
postoperatively for the degree of repigmentation and side effects. RESULTS:
In the MPG group, 644 grafts, 2.5 mm in size, were placed on a total
vitiliginous area of 521.25 cm2, whereas in the SSG group, 153 grafts
covered a 1,489 cm2 recipient area. Three months postoperatively, in the
first group, 15 cases (44.1%) showed very good to excellent (> 75%)
repigmentation compared with 25 cases (83.3%) in group 2. Following MPG, 81
grafts (12.57%) were rejected. Cobblestoning was the main side effect,
occurring in 13 cases (38.23%), and a variegated appearance was observed in
7 (20.58%) patients. The complications noted after SSG were achromic
fissuring in four (13.3%) cases, graft contracture in four grafts (2.61%) in
three patients, and rejection of seven grafts (4.57%) in one case;
tire-pattern appearance in two patients (6.6%); milia formation in four
(13.3%) patients; and depigmentation of the grafts in two (6.6%) cases. In
both groups, superficial scarring was noted at the donor site in all cases,
whereas hypertrophic scarring occurred in 3 (10%) patients after SSG.
CONCLUSION: SSG carries a distinct advantage over MPG in producing excellent
cosmetic matching over larger areas using fewer grafts, especially over the
face and extremities.

BACKGROUND/PURPOSE: There is no definite cure for vitiligo; however,
treatment responses with photobiological modalities are quite acceptable. Of
all these, narrow-band UVB phototherapy was proposed rather recently.
Calcipotriol has been shown to have stimulating activity on melanogenesis
besides immunomodulatory and anti-inflammatory effects. This study was
performed to determine whether adding topical calcipotriol to narrow-band
UVB phototherapy enhances the efficacy of treatment. METHODS: In this
prospective, single-blinded (investigator), right-left comparison clinical
study, 20 patients with generalized vitiligo were enrolled. Symmetrical
lesions with similar sizes, bilaterally distributed on arms, legs, hands,
feet or trunk were selected as reference lesions. In addition to narrow-band
UVB, totally 96 treatment sessions, received two or three times weekly, the
patients were asked to apply 0.005% topical calcipotriol on the selected
side of the reference lesions twice daily. Then, they were monitored at the
end of every 24-session interval. RESULTS: Cosmetically acceptable
repigmentation was observed in 55% (11/20) of the patients without taking
calcipotriol into account. There was statistically significant better
response on the side that calcipotriol was not applied at the 24th session
(P < 0.05). No statistically significant difference was found between the
calcipotriol-treated and non-treated sides at 48th, 72th, and 96th sessions
(P > 0.05). CONCLUSION: Our data confirm that, narrow-band UVB phototherapy
is effective by itself in vitiligo, and show that adding topical
calcipotriol does not improve treatment outcome.

Topical 0.05% clobetasol propionate versus 1% pimecrolimus
ointment in vitiligo.
Coskun B, Saral Y, Turgut D.
Firat University Faculty of Medicine, Department of Dermatology, Elazig-Turkey.
basakkc@hotmail.com
Vitiligo is a common skin condition resulting from loss of normal melanin
pigments in the skin which produces white patches. Topical corticosteroids
are indicated for the treatment of limited areas of vitiligo. Pimecrolimus,
which inhibits calcineurin, has recently been shown to be effective for the
treatment of vitiligo. We performed a prospective study to evaluate the
efficacy of the 0.05% clobetasol propionate and 1% pimecrolimus in the
treatment of vitiligo. Ten patients with virtually bilateral symmetrical
lesions of vitiligo were included. 0.05% clobetasol propionate was applied
twice daily over the lesion on right side of the body, and topical 1%
pimecrolimus was applied twice daily over the lesion on left side of the
body. It was determined that both treatment modalities resulted in a
comparable rate of repigmentation. Response to treatment was varied
according to the anatomical location of the lesions where better results
were seen on the trunk and extremities. Results from this pilot study
indicate that topical 1% pimecrolimus is as effective as clobetasol
propionate in restoring skin disfiguring due to vitiligo. For a better
conclusive statement further studies involving larger groups of patients
should be performed.

New treatment modalities for vitiligo: focus on topical
immunomodulators.
Kostovic K, Pasic A.
Department of Dermatology and Venerology, Zagreb University Hospital Center,
Salata 4, Zagreb, HR-100000, Croatia. kreso.kostovic@zg.htnet.hr
The development of effective treatment modalities for vitiligo is dependent
on an understanding of the events leading to depigmentation. However, the
exact pathogenesis of vitiligo is still mostly unknown. Abnormalities in
both humoral and cell-mediated immunity have been documented in vitiligo
patients and they present a basis for using immunomodulating agents, such as
corticosteroids and macrolide immunomodulators, in the treatment of vitiligo.
Macrolide immunomodulators, such as tacrolimus and pimecrolimus, which can
be used topically, are known as topical immunomodulators (TIMs). TIMs
inhibit the action of calcineurin, and consequently inhibit T-cell
activation and the production of various cytokines; this is considered the
working mechanism of action of TIMs in vitiligo. Several small studies and
case reports on the use of TIMs in vitiligo have been published so far.
Tacrolimus achieves better results on the face and neck than on other body
areas.Particular advantages of TIMs are safety in treating these areas
because of lack of skin atrophy and good tolerability. The incidence of
application site adverse events in vitiligo seems to be lower than in the
treatment of atopic dermatitis. On the face and neck, TIMs may become a
useful tool in the treatment of adults and children with vitiligo despite
possibly lower efficacy than topical corticosteroids. Further, larger,
controlled clinical studies are warranted to determine the definite role of
TIMs as monotherapy or in combination with other modalities in the treatment
of vitiligo.

Fluticasone propionate - the first carbothioate corticosteroid - has been
classified as a potent anti-inflammatory drug for dermatological use. It is
available as 0.05% cream and 0.005% ointment formulations for the acute and
maintenance treatment of patients with dermatological disorders such as
atopic dermatitis, psoriasis and vitiligo. This glucocorticoid is
characterized by high lipophilicity, high glucocorticoid receptor binding
and activation, and a rapid metabolic turnover in skin. Although skin
blanching following fluticasone propionate exceeds that of corticosteroids
of medium strength, several clinical trials demonstrate a low potential for
cutaneous and systemic side-effects, even in difficult-to-treat areas like
the face, the eyelids and intertriginous areas. Even among paediatric
patients with atopic dermatitis, fluticasone propionate proved to be safe
and effective. These pharmacological and clinical properties are reflected
by the high therapeutic index of this glucocorticoid. Copyright 2005 S.

Narrow-band UVB for the treatment of vitiligo: an emerging
effective and well-tolerated therapy.
Kanwar AJ, Dogra S, Parsad D, Kumar B.
Department of Dermatology, Venereology, and Leprology, Postgraduate
Institute of Medical Education and Research, Chandigarh, India. sundogra@hotmail.com
BACKGROUND: Vitiligo is an acquired depigmentation disorder of great
cosmetic importance, affecting 1% of the general population.
Photochemotherapy is the most commonly used treatment modality in extensive
vitiligo, but is associated with many short- and long-term side-effects.
Recently, narrow-band ultraviolet B (NBUVB) therapy has been reported to be
an effective and safe therapeutic option in patients with vitiligo. We
studied the efficacy and safety of NBUVB (311 nm) therapy in Indian patients
with generalized vitiligo. METHODS: Fourteen patients (six males and eight
females), aged 12-56 years, with generalized vitiligo, were treated thrice
weekly with NBUVB radiation therapy for a maximum period of 1 year. RESULTS:
At the end of 1 year, 10 patients (71.4%) had marked to complete
repigmentation and two each (14.3%) had moderate or mild repigmentation.
Repigmentation sites showed an excellent color match. The response to
therapy was correlated with the sites of involvement, duration of disease,
and compliance to therapy. Adverse events were limited and transient.
CONCLUSION: NBUVB therapy is effective and safe in Indian patients with
vitiligo. Long-term follow up is required, however, to establish the
stability of repigmentation.

the Netherlands.
ABSTRACT Long-term treatments for chronic diseases such as vitiligo need to
be evaluated for their clinical efficacy. Assessment of the quality of life
(QOL), however, may provide the most relevant information on the actual
benefit for these patients. In this study we evaluated QOL after long-term
narrowband ultraviolet (UV) B for the treatment of vitiligo. All patients,
with long-term stable vitiligo vulgaris, who were treated at our clinic
during the last 4 years received specifically for this study a designed QOL
questionnaire, which included questions about general well-being, camouflage
and psychosocial aspects; 71.4% of the patients responded. Most patients
indicated an improvement on a psychological level, but an increase in
camouflaging. The present study shows that, after long-term narrowband UVB
phototherapy, skin appearance does not play a major role in the life of
vitiligo patients, while well being only improved in a minority of patients.

Gargoom AM, Duweb GA, Elzorghany AH, Benghazil M, Bugrein OO.
Dermatology Department, Jamahiriya Hospital, Benghazi, Libya.
Eighteen patients with a clinical diagnosis of vitiligo, aged between three
and 12 years (mean 8.9 years), were enrolled in this study in order to
evaluate the efficacy and tolerability of topical calcipotriol in the
treatment of childhood vitiligo. Six patients (33.3%) were males and 12 were
females (66.7%). Fourteen patients (77.8) had focal vitiligo, two (11.1%)
had mucosal vitiligo and two (11.1%) had segmental vitiligo. The face was
involved in 11 patients (61.1%). The treatment was applied twice daily as 50
microg/gm cream in nine patients and as ointment in the remaining patients.
Treatment assessment was carried out clinically at 2 weeks, and then monthly
for 4-6 months. Four patients (28.6%) were excluded from the study (one due
to irritation and three due to lost contact in follow-up). Fourteen patients
(71.4%) completed the treatment course (> 3 months). Of the treated
patients, ten (77.8%) showed improvement and four patients (22.2%) had no
response. Among responders, three patients (21.4%) showed complete
resolution, four (28.6%) showed 50%-80% improvement and three patients
(21.4%) showed 30% to < 50% improvement. Only one patient (5.5%) developed
irritation. In conclusion, calcipotriol is an effective treatment in
vitiligo. Better results are obtained with ointment than with cream.
Calcipotriol can be helpful in children in whom potent steroids and PUVA are
not advisable.

SL, Paller AS.
Department of Dermatology, Division of Pediatric Dermatology, St
Luke's-Roosevelt Hospital Center, New York, NY, USA.
BACKGROUND: Vitiligo is an autoimmune disorder characterized by loss of
pigmentation. Phototherapy and application of topical corticosteroids are
most commonly prescribed. However, these therapies are often not effective
and use of corticosteroids on the face may lead to cutaneous atrophy,
telangiectasia, and ocular complications. OBJECTIVE: We sought to assess the
efficacy of topical tacrolimus ointment in the treatment of pediatric
vitiligo. METHODS: A retrospective review was performed of 57 pediatric
patients with vitiligo at two clinical sites. Patients were treated with
tacrolimus ointment for at least 3 months. Clinical responses were
documented during clinic visits, and by pretacrolimus and posttacrolimus
photography. RESULTS: At least partial response was noted to tacrolimus
ointment on the head and neck in 89%, and on the trunk and extremities in
63% of patients. Facial vitiligo of the segmental type showed the best
response rate. Two patients initially experienced burning on application.
CONCLUSIONS: Topical tacrolimus ointment is an effective alternative therapy
for childhood vitiligo, particularly involving the head and neck.

Topical calcipotriene and narrowband ultraviolet B in the
treatment of vitiligo.
Kullavanijaya P, Lim HW.
Department of Dermatology, Henry Ford Hospital, 2999 West Grand Boulevard,
Detroit, MI 48202, USA.
BACKGROUND: Treatment of vitiligo, despite significant advances made in the
past few years, remains to be a challenge. Narrowband ultraviolet (NB-UVB)
has emerged as an important therapeutic option for this condition.
OBJECTIVE: To evaluate whether the combination of calcipotriene ointment and
NB-UVB could enhance the efficacy of NB-UVB alone. METHODS: An open,
bilateral comparison study was performed in 20 patients with symmetrical
vitiligo between August 2001 and October 2002. All patients received NB-UVB
three times per week. Calcipotriene ointment was applied to lesions on the
left side of the body. Response was graded visually as significant (66-100%
repigmentation), moderate (26-65%), mild (10-25%), and minimal (< 10%).
RESULTS: Seventeen patients (six females, 11 males) completed the study.
Eight patients (8/17=47%) had significant repigmentation after 67-180
treatments, six patients (35%), one patient (6%), and two patients (12%) had
moderate, mild, and minimal repigmentation after 40-160, 57, and 14-21
treatments, respectively. Nine of the 17 patients had an appreciably better
improvement on the NB-UVB and calcipotriene side by 29-114 treatments. In
six of these patients, differences were still observed at the end of the
study period. No side effects were noted. CONCLUSION: Combination therapy of
topical calcipotriene and NB-UVB is a therapeutic option that could be
considered in the management of patients with vitiligo.

Long-term follow-up study of segmental and focal vitiligo
treated by autologous, noncultured melanocyte-keratinocyte cell
transplantation.
Mulekar SV.
Noble Clinic, Pune, India. dr_mulekar@vsnl.com
OBJECTIVE: To evaluate long-term efficacy and safety of
melanocyte-keratinocyte cell transplantation in the management of segmental
and focal vitiligo. DESIGN: A simpler and modified method based on that of
Olsson and Juhlin was performed. This method uses a shaved biopsy skin
sample up to one tenth the size of the recipient area. The skin sample is
incubated, and the cells are mechanically separated using trypsin-EDTA
solution and then centrifuged to prepare a suspension. Cell suspension is
then applied to the dermabraded depigmented skin area, and a collagen
dressing is applied to keep it in place. PATIENTS: Fifty patients with
segmental and 17 with focal vitiligo were treated. One patient with
segmental and 2 with focal vitiligo did not attend any follow-up visits. The
remaining patients were observed for a period of up to 5 years.
INTERVENTION: Autologous, noncultured melanocyte-keratinocyte cell
transplantation. MAIN OUTCOME MEASURE: Repigmentation was graded as
excellent with 95% to 100% pigmentation, good with 65% to 94%, fair with 25%
to 64%, and poor with 0% to 24% of the treated area. RESULTS: In the
segmental vitiligo group, 41 patients (84%) showed excellent, 3 (6%) good,
and 5 (10%) poor pigmentation, which was retained until the end of the
respective follow-up period. In the focal vitiligo group, 11 patients (73%)
showed excellent, 1 (7%) fair, and 3 (20%) poor pigmentation, which was
retained until the end of the respective follow-up period. CONCLUSIONS:
Melanocyte-keratinocyte cell transplantation is a simple, safe, and
effective surgical therapy. Patients with segmental and focal vitiligo can
experience a prolonged disease-free period, which may extend through the
rest of their lives.

Double-blind placebo-controlled study of autologous
transplanted epidermal cell suspensions for repigmenting vitiligo.
van Geel N, Ongenae K, De Mil M, Haeghen YV, Vervaet C, Naeyaert JM.
Department of Dermatology, Ghent University Hospital, 9000 Ghent, Belgium.
OBJECTIVES: To investigate the efficacy of epidermal noncultured cellular
grafting in patients with vitiligo and the role of postinflammatory,
spontaneous, or UV-induced pigmentation in obtaining repigmentation. DESIGN:
A prospective, randomized, double-blind, placebo-controlled study. SETTING:
Ambulatory patients in an institutional practice. Patients were followed up
for 3 to 12 months. PATIENTS: A total of 33 paired, symmetrically
distributed leukodermic lesions, all resistant to therapy, were observed in
28 patients. Nineteen patients appeared to have a stable vitiligo (group 1),
whereas there was doubt about the stability of the disease in 9 patients
(group 2). INTERVENTION: After laser ablation, a hyaluronic acid-enriched
cellular graft was applied to 1 lesion while the paired lesion received
placebo. Three weeks later all lesions were exposed to UV irradiation twice
per week for approximately 2 months. MAIN OUTCOME MEASURES: Primarily, the
percentage of repigmentation was assessed after 3, 6, and 12 months using a
digital image analysis system. The repigmentation pattern was also evaluated
after 1 and 3 months. RESULTS: A strongly significant difference between
cellular grafts and placebo was observed after 3, 6, and 12 months (P<.001,
P = .002, and P = .002, respectively). In group 1, repigmentation of at
least 70% of the treated area was achieved in 55%, 57%, and 77% of the
actively treated lesions 3, 6, and 12 months after treatment, whereas in
group 2 repigmentation of at least 70% of the treated area was not observed
at any time point. The repigmentation pattern was diffuse in 94% of the
responding patients. CONCLUSIONS: After a strict preoperative selection for
disease stability, transplantation resulted in repigmentation of at least
70% of the treated area in most actively treated vitiligo lesions.
Repigmentation was primarily caused by the transplanted melanocytes.

Topical tacrolimus and the 308-nm excimer laser: a
synergistic combination for the treatment of vitiligo.
Passeron T, Ostovari N, Zakaria W, Fontas E, Larrouy JC, Lacour JP, Ortonne
JP.
Department of Dermatology, Hopital de l'Archet 2, Nice, France. t.passeron@free.fr
OBJECTIVE: To compare the efficacy of combined tacrolimus and 308-nm excimer
laser therapy vs 308-nm excimer laser monotherapy in treating vitiligo.
DESIGN: Comparative, prospective, randomized, intraindividual study.
PATIENTS: Fourteen patients, aged 12 to 63 years, with Fitzpatrick skin
types II to IV. INTERVENTION: For each patient, 4 to 10 target lesions were
chosen. The treatment applied to each target lesion was randomized by
drawing lots. Each lesion was treated twice a week by the 308-nm excimer
laser, for a total of 24 sessions. Initial fluences were 12 mcal/cm(2) (50
mJ/cm(2)) less than the minimal erythemal dose in vitiliginous skin. Then,
fluences were increased by 12 mcal/cm(2) every second session. Moreover,
topical 0.1% tacrolimus ointment was applied twice daily on target lesions
receiving the combined tacrolimus and excimer laser treatment (group A).
Group B target lesions received only excimer laser monotherapy. For each
treated lesion, the untreated lesion on the opposite side served as the
control. Tolerance was evaluated by a visual analog scale, and secondary
events were recorded at each session. MAIN OUTCOME MEASURE: Treatment
efficacy, which was blindly evaluated by 2 independent physicians by direct
and polarized light photographs taken before and after treatment. RESULTS:
Forty-three lesions were treated (23 in group A and 20 in group B). All
patients completed the study. Repigmentation was observed in all group A
lesions (100%) and in 17 (85%) of the 20 group B lesions. Repigmentation was
not observed in the untreated lesions (control group). A repigmentation rate
of 75% or more was obtained in 16 (70%) of the 23 group A lesions and in 4
(20%) of the 20 group B lesions. In UV-sensitive areas (the face, neck,
trunk, and limbs, with the exception of bony prominences and extremities),
10 (77%) of 13 group A lesions had a repigmentation rate of 75% or more vs 4
(57%) of 7 group B lesions. In classically UV-resistant areas, 6 (60%) of 10
group A lesions had a repigmentation rate of 75% or more vs 0 of the 13
group B lesions. The mean number of sessions necessary for an improvement of
repigmentation was 10 in group A and 12 in group B. Adverse effects have
been limited, and tolerance was excellent. CONCLUSIONS: The combination
treatment of 0.1% tacrolimus ointment plus the 308-nm excimer laser is
superior to 308-nm excimer laser monotherapy for the treatment of
UV-resistant vitiliginous lesions (P<.002). The efficacy and the good
tolerance of the 308-nm excimer laser in monotherapy for treating localized
vitiligo were also confirmed, but this treatment regimen should be proposed
only for UV-sensitive areas.

Treatment of vitiligo by 308-nm excimer laser: an evaluation
of variables affecting treatment response.

Ortonne JP.
Department of Dermatology, Hopital de l'Archet 2, Nice, France.
BACKGROUND AND OBJECTIVES: To determine the true efficacy of the 308-nm
excimer laser for the treatment of vitiligo, while taking into account
confounding factors such as anatomic site of treatment, age, sex, skin type,
MED, and duration of evolution of the vitiligo. STUDY DESIGN/MATERIALS AND
METHODS: Thirty-five patients with vitiligo were included. Each lesion was
treated twice a week by the 308-nm excimer laser for a maximum of 24
sessions. Efficacy was blindly evaluated by two independent physicians.
RESULTS: Repigmentation was noted in 46 plaques/52 (88.5%). Repigmentation
rate (75%) was obtained in 14 (26.9%). In "UV sensitive" areas (face, neck,
trunk), 8/14 lesions (57.1%) had a repigmentation rate, 75% versus 6/38
(15.8%) in "UV resistant" areas (bony prominences and extremities) (P =
0.031). No relationship could be established between response to the
treatment and the following variables: age, sex, skin type, MED, and
duration of evolution of the vitiligo (respectively, P = 1, 0.666, 0.566,
0.628, 0.521). CONCLUSIONS: An aesthetically reasonable result is achieved
essentially in "UV sensitive" areas, thus appearing to be the appropriate
places of choice for this treatment.

Calcipotriene and corticosteroid combination therapy for vitiligo.
Travis LB, Silverberg NB.
Department of Dermatology, St. Luke's-Roosevelt Hospital Center, New York,
New York.
Corticosteroids and photochemotherapy, using a combination of psoralen and
ultraviolet A (PUVA) exposure, are the most widely prescribed therapies for
vitiligo. These treatments are not uniformly effective and many patients
have inadequate responses. Calcipotriene has been shown to be effective in
adults and children with psoriasis when used as monotherapy and in
combination with corticosteroids and phototherapy. We hypothesized that
since the mechanisms of action for calcipotriene and corticosteroids are
different, patients may develop more repigmentation with a combination of
the two agents, while decreasing the side effects from both agents. Twelve
patients with vitiligo (average age 13.1 years) were advised to use topical
corticosteroids in the morning and topical calcipotriene in the evening. Of
the 12 patients, 83% responded to therapy, with an average of 95%
repigmentation by body surface area. Four of the patients who responded had
previously failed trials of topical corticosteroids alone. All of the
patients in this group had repigmentation. Eyelid and facial skin responded
best to this therapy. None of the patients had adverse reactions to the
treatment. Our results show that topical calcipotriene in combination with
corticosteroids can repigment vitiligo, even in those patients who were
previous topical corticosteroid failures.

Los Angeles, USA. pegrimesmd@earthlink.net
BACKGROUND: Previous studies have documented humoral and cell-mediated
immunologic defects in patients with vitiligo. OBJECTIVE: This 24-week study
assessed the efficacy and safety of tacrolimus 0.1% ointment in patients
with generalized vitiligo as well as the pretreatment and post-treatment
expression of cytokines in the depigmented and normal skin of patients
compared with controls. METHODS: Twenty-three patients were enrolled in this
investigation, and 19 patients completed the study; 8 were male and 11 were
female. Fifteen age-, race-, and sex-matched control subjects were also
included. Patients were treated with tacrolimus 0.1% ointment applied twice
daily. Repeat evaluations were performed at 4, 8, 12, 16, 20, and 24 weeks.
Three-millimeter punch biopsy specimens were taken from the depigmented,
non-sun-exposed skin and adjacent normal skin of patients at baseline and 24
weeks, and from normal, non-sun-exposed skin of controls. Cellular messenger
RNA expression for interleukin 2 (IL-2), IL-4, IL-10, tumor necrosis factor
alfa (TFN-alpha), and interferon gamma (IFN-gamma) were determined by
real-time quantitative polymerase chain reaction. RESULTS: At 24 weeks, 17
of 19 patients (89%) achieved varying levels of repigmentation. There was a
statistically significant decrease in overall disease severity scores at 24
weeks. Thirteen patients (68%) had greater than 75% repigmentation of face
and/or neck lesions. Signs and symptoms of irritation were minimal. At
baseline, compared with healthy controls, vitiligo patients demonstrated a
statistically significant increase in the expression of IFN-gamma in
involved and adjacent uninvolved skin (P=.05 and P=.02, respectively);
significantly increased TNF-alpha expression in involved and uninvolved skin
(P=.01 and P=0.02, respectively); and significantly increased IL-10
expression in involved and uninvolved skin (P=.01 and P=.04, respectively).
Posttreatment, TNF-alpha expression decreased in the depigmented and
adjacent uninvolved skin (P <.001). There was no statistically significant
change in IL-10 or IFN-gamma posttreatment. These data suggest that
tacrolimus 0.1% ointment is a safe and effective therapy for patients with
vitiligo. It further suggests that an imbalance in local cytokine expression
may play a role in the pathogenesis of vitiligo. Suppression of TNF-alpha
after topical tacrolimus application may be associated with repigmentation
of vitiligo.

BACKGROUND: Despite the availability of various medical treatments for
vitiligo, a large percentage of patients fail to achieve satisfactory
results. Surgical techniques offer a potential solution for patients with
vitiligo who fail to respond to medical treatments. OBJECTIVE: We evaluated
the practicality in treating vitiligo by using cultured autologous pure
melanocytes and investigated the different results among stable localized
vitiligo, stable generalized vitiligo, and active generalized vitiligo.
METHODS: In all, 120 patients with vitiligo were treated with
transplantation of autologous cultured pure melanocyte suspension after
carbon-dioxide laser abrasion. RESULTS: Patients with stable localized
vitiligo experienced the highest percentage of excellent repigmentation with
84% achieving 90% to 100% coverage, followed by 54% of patients with stable
generalized vitiligo, whereas only 14% of patients with active generalized
vitiligo experienced good repigmentation. Age and sex of the patients, and
size and location of the lesions, did not show significant influence on the
results of transplantation. CONCLUSION: Autologous cultured pure melanocyte
suspension combined with carbon-dioxide laser abrasion is an effective
treatment for patients with stable vitiligo who fail to respond to medical
treatments, especially for those with stable localized vitiligo.

The use of the 308-nm excimer laser for the treatment of vitiligo.
Hadi SM, Spencer JM, Lebwohl M.
Department of Dermatology, Mount Sinai School of Medicine, New York, NY
10029, USA. smhadi@Dr.com
BACKGROUND: Recent reports show that 308-nm excimer laser may be an
effective and safe method for the treatment of vitiligo, which is usually
resistant to other available treatment methods. OBJECTIVE: The objective was
to study the effectiveness of the new 308-nm excimer laser for the treatment
of vitiligo. METHODS: A retrospective chart review of thirty-two patients
with 55 spots of vitiligo were enrolled; a population-based sample was
studied that included men and women, adults and children, with different
ethnic backgrounds. The treatment was started with the lowest dose, which is
100 mJ/cm(2) (comparable to one minimal erythema dose value and one
multiplier). Depending on Fitzpatrick skin type, the dose was raised
gradually in a stepwise fashion. In skin types I to II, the same does was
repeated twice before going up to avoid burns. Patients were treated for 30
sessions, or 75% repigmentation, whichever comes first. RESULTS: Overall 55
spots were treated: 29 (52.8%) had 75% pigmentation or greater, and 35
(63.7%) had 50% pigmentation or greater. The best results were on the face:
of the 21 spots treated 15 (71.5%) had 75% pigmentation, and 16 (76.2%) had
50% pigmentation or greater. Other areas (neck, extremities, trunk, and
genitals) had moderate response in comparison to the face. The least
response was on the hands and feet; of the 5 spots treated only 20% showed
50% pigmentation or more. CONCLUSION: Slightly more than 50% of the patients
tested showed 75% or more pigmentation of their lesions, after 30 treatments
or less; most of the responders had Fitzpatrick skin type III and above. All
the untreated patches (controls) remained unchanged. This demonstrates that
the 308-nm excimer laser is an effective method of treatment for vitiligo.

Parametric modeling of narrowband UV-B phototherapy for vitiligo
using a novel quantitative tool: the Vitiligo Area Scoring Index.
Hamzavi I, Jain H, McLean D, Shapiro J, Zeng H, Lui H.
Division of Dermatology, Department of Medicine, Vancouver Coastal Health
Research Institute, University of British Columbia, Vancouver, Canada.
BACKGROUND: There is currently no quantitative tool for evaluating vitiligo
treatment response using parametric methods. OBJECTIVE: To develop and apply
a simple clinical tool, the Vitiligo Area Scoring Index (VASI), to model the
response of vitiligo to narrowband UV-B (NB-UV-B) phototherapy using
parametric tests. DESIGN: Prospective, randomized, controlled, bilateral
left-right comparison trial. SETTING: North American tertiary care,
university-affiliated phototherapy center. PATIENTS: Patients older than 18
years with stable vitiligo involving at least 5% of their total body surface
in a symmetric distribution. INTERVENTION: Treatment with NB-UV-B was given
3 times a week to half of the body on all patients for either 60 treatments
or 6 months. The contralateral side served as a no-treatment control. MAIN
OUTCOME MEASURE: Repigmentation was assessed using the VASI, which was based
on a composite estimate of the overall area of vitiligo patches at baseline
and the degree of macular repigmentation within these patches over time. The
VASI was validated separately against physician and patient global
assessments. The overall reductions in VASI for NB-UV-B and control groups
were modeled by multilevel regression with random effects and compared
parametrically. RESULTS: The VASI scoring correlated well with both patient
and physician global assessments (P =.05 and P<.001, respectively, using
ordinal logistic regression). The extent of repigmentation after 6 months on
the treated side was 42.9% (95% confidence interval, 26.7%-59.0%) vs 3.3%
(95% confidence interval -19.3% to 30.0%) on the untreated side (P<.001). A
significant difference between control and NB-UV-B groups was apparent
within the first 2 months of therapy. The legs, trunk, and arms were much
more likely to repigment than the feet and hands. CONCLUSIONS: The VASI is a
quantitative clinical tool that can be used to evaluate vitiligo
parametrically. Patients treated with NB-UV-B can be expected to achieve
approximately 42.9% repigmentation of their vitiligo after 6 months of
treatment, with the greatest response being achieved over the trunk and
nonacral portions of the extremities.

Topical immunomodulators in dermatology.
Khandpur S, Sharma VK, Sumanth K.
Department of Dermatology and Venereology, All India Institute of Medical
Sciences, New Delhi - 110 029, India. shaifalikhandpur@eth.net
Topical immunomodulators are agents that regulate the local immune response
of the skin. They are now emerging as the therapy of choice for several
immune-mediated dermatoses such as atopic dermatitis, contact allergic
dermatitis, alopecia areata, psoriasis, vitiligo, connective tissue
disorders such as morphea and lupus erythematosus, disorders of
keratinization and several benign and malignant skin tumours, because of
their comparable efficacy, ease of application and greater safety than their
systemic counterparts. They can be used on a domiciliary basis for longer
periods without aggressive monitoring. In this article, we have discussed
the mechanism of action, common indications and side-effects of the commonly
used topical immunomodulators, excluding topical steroids. Moreover, newer
agents, which are still in the experimental stages, have also been
described. A MEDLINE search was undertaken using the key words "topical
immunomodulators, dermatology" and related articles were also searched. In
addition, a manual search for many Indian articles, which are not indexed,
was also carried out. Wherever possible, the full article was reviewed. If
the full article could not be traced, the abstract was used.

Toxic effects of ultraviolet radiation on the
skin.
Matsumura Y, Ananthaswamy HN.
Department of Dermatology, Kansai Medical University, Osaka 570-8507,
Japan. matsumy@takii.kmu.ac.jp
Ultraviolet (UV) irradiation present in sunlight is an environmental
human carcinogen. The toxic effects of UV from natural sunlight
and therapeutic artificial lamps are a major concern for human
health. The major acute effects of UV irradiation on normal human
skin comprise sunburn inflammation (erythema), tanning, and local
or systemic immunosuppression. At the molecular level, UV irradiation
causes DNA damage such as cyclobutane pyrimidine dimers and (6-4)
photoproducts, which are usually repaired by nucleotide excision
repair (NER). Chronic exposure to UV irradiation leads to photoaging,
immunosuppression, and ultimately photocarcinogenesis. Photocarcinogenesis
involves the accumulation of genetic changes, as well as immune
system modulation, and ultimately leads to the development of
skin cancers. In the clinic, artificial lamps emitting UVB (280-320
nm) and UVA (320-400 nm) radiation in combination with chemical
drugs are used in the therapy of many skin diseases including
psoriasis and vitiligo. Although such therapy is beneficial, it
is accompanied with undesirable side effects. Thus, UV radiation
is like two sides of the same coin--on one side, it has detrimental
effects, and on the other side, it has beneficial effects.

The psychological aspects of vitiligo.
Silvan M.
Department of Dermatology, St. Luke's-Roosevelt Hospital Center,
New York, New York 10025, USA. mes57@columbia.edu
Dermatologists are likely to be confronted with patients who
present with a wide range of psychiatric issues and problems.
Writers on psychocutaneous medicine have described a variety of
conditions that represent the interplay between the psyche and
the soma. Vitiligo is one such disease and will be the focus of
this article. Specifically, 3 areas will be examined: (1) the
psychological impact vitiligo has on patients, (2) how psychological
factors contribute to the etiology and course of the illness,
and (3) the benefits of offering adjunctive psychological treatment.
By exploring these aspects of vitiligo in more detail, I hope
to illustrate the profound importance psychological factors play
in this disease and the value of incorporating a psychological
approach in its treatment.

Treatment of vitiligo with local khellin and UVA:
comparison with systemic PUVA.
Valkova S, Trashlieva M, Christova P.
Department of Dermatology and Venereology, Department of Public
Health, Medical University, Pleven, Bulgaria.
Vitiligo is an idiopathic leukoderma often with a progressive
course causing destruction of melanocytes. The best methods for
achieving cosmetically acceptable re-pigmentation of affected
skin appear to be both local and systemic PUVA. They may, however,
cause serious side effects, which is an argument for conducting
research into new, equally effective photo-chemotherapeutic agents.
One of these agents is khellin. We conducted a pilot study in
33 patients to evaluate the effectiveness of local KUVA and systemic
PUVA therapy for vitiligo and to compare them in terms of the
degree of re-pigmentation, duration of treatment, number of procedures,
total UVA dose and side effects. Local KUVA required longer duration
of treatment and higher UVA doses. KUVA-induced re-pigmentation
depended on the age of the patients (r = -0.61, P = 0.001), and
better results were achieved with younger individuals [% re-pigmentation
= 81.76 - (1.48 x age in years)]. No side effects were observed
in cases of local KUVA treatment. Erythema, itching and gastro-intestinal
disturbances occurred with some patients treated with PUVA. The
results demonstrate that local KUVA may effectively induce re-pigmentation
of vitiligo-affected skin areas to a degree comparable to that
achieved when using systemic PUVA, provided that treatment duration
is long enough.

Treatment of vitiligo with the 308 nm excimer
laser.
Esposito M, Soda R, Costanzo A, Chimenti S.
Department of Dermatology, University of Rome 'Tor Vergata', Italy.
Several therapeutic modalities have been proposed for the treatment
of vitiligo either to achive repigmentation in the lesions or
to stabilize the disease. Narrow-band UVB therapy has been shown
to be effective and safe for use in the management of vitiligo;
its wavelength is not so different from 308 nm XeCl excimer laser
radiation. We present an open and uncontrolled pilot study of
24 patients (12 men, 12 women) in whom vitiligous patches were
treated twice a week, for 9 months with 308 nm XeCl laser radiation.
Seven of the 24 patients showed greater than 75% repigmentation,
six patients showed repigmentation of between 25 and 75% and six
patients showed less than 25% repigmentation. In five patients
no signs of repigmentation were noted. The therapeutic benefit
was stable during the 12-month follow-up period. Although these
results are promising, treatment has so far been limited to small
numbers of patients and a short follow-up period. Other prospective
studies are needed to assess the efficacy of this treatment modality.

Topical melagenine for repigmentation in twenty-two
child patients with vitiligo on the scalp.
Xu AE, Wei XD.
Department of Dermatology, Third People's Hospital of Hangzhou,
Hangzhou 310009, China.
BACKGROUND: The purpose of this study was to evaluate the efficacy
of topical melagenine for repigmentation in child patients with
vitiligo on the scalp. METHODS: Twenty-two child patients with
vitiligo on the scalp were treated with 1.2 mg/ml aqueous melagenine
in combination with 20 minutes of infrared exposure twice daily.
RESULTS: In 4 patients (18.2%), melagenine treatment in combination
with infrared exposure led to complete recovery; in 6 patients
(27.3%), treatment was shown to be effective; in 8 patients (36.3%),
treatment led to improvements in patient condition; and only 4
patients (18.2%) showed no response after 1 - 2 treatment sessions.
The general effective rate of melagenine-infrared combination
treatment was 45.5% for the children with vitiligo on the scalp,
and treatment was accompanied by minimal side effects. CONCLUSION:
Melagenine may be efficacious and a safe treatment option for
childhood vitiligo affecting the scalp.

Combined excimer laser and topical tacrolimus
for the treatment of vitiligo: a pilot study.
Kawalek AZ, Spencer JM, Phelps RG.

Dermatologic Surgery, Mount Sinai School of Medicine, New York,
New York.
BACKGROUND. : Vitiligo is an acquired skin disorder that is
characterized by well-defined, often symmetric white patches.
Although current therapeutic modalities are directed toward increasing
melanocyte melanin production, few treatment modalities address
the immunologic nature of the disease. OBJECTIVE. : To determine
whether excimer laser, a known therapeutic modality, in combination
with tacrolimus, a topical immunomodulator, accelerate response
time and/or improve the degree of response in patients with this
disorder. METHODS. : Eight subjects diagnosed with vitiligo were
recruited to participate in this institutional review board-approved
double-blind, placebo-controlled study. Twenty-four symmetric
vitiliginous patches (elbows, knees) from eight subjects received
excimer laser treatment three times per week for 24 treatments
or 10 weeks. Additionally, topical tacrolimus 0.1% ointment (Protopic)
and placebo (Aquaphor) were applied to randomized patches (left
or right) twice daily throughout the length of the trial. Vitiliginous
patches were monitored with photographs at baseline, every 2 weeks,
and 6 months after treatment. Biopsies were performed on subjects
with significant results. RESULTS. : Twenty vitiliginous patches
from six subjects qualified for evaluation. Fifty percent of patches
treated with combination excimer laser and tacrolimus achieved
a successful response (75% repigmentation) compared with 20% for
the placebo group. Subjects who responded successfully repigmented
faster (19%) with combination therapy compared with excimer laser
alone. Additionally, three subjects experienced transient hyperpigmentation
in lesions treated with combination therapy. CONCLUSION. : Combining
topical immunomodulators with known phototherapeutic modalities
may represent a key advancement in the treatment of disease.

Hypopigmentary skin disorders: current treatment
options and future directions.
Hartmann A, Brocker EB, Becker JC.
Department of Dermatology, University Hospital Wuerzburg, Wuerzburg,
Germany.
Alterations of skin and hair pigmentation are important features
that have warranted treatment from ancient history on up to modern
time. In some cultures, even today patients with vitiligo are
regarded as social outcasts and are affected considerably both
emotionally and physically. This article presents current options
and future directions for the treatment of hypopigmentary disorders.
Whereas with congenital disorders, such as albinism and phenylketonuria,
no causal therapy has been established up to now, several treatment
options for acquired hypopigmentary disorders have been investigated.
In particular, in vitiligo, one of the most prevalent hypopigmentary
disorders, a number of treatment modalities have been employed
in the past 30 years. However, most of them are only able to palliate,
not cure, the disease. Depending on the distribution of the hypopigmented
lesions (localised or generalised) and the state of the disease
(active or stable), several therapeutic options, for example phototherapy,
surgical skin grafts, autologous melanocyte transplantation and
immunomodulators, can be applied alone or in combination. For
phototherapy, because of unfavourable results and adverse effects,
ultraviolet (UV) A has been largely replaced by narrow-band UVB
for repigmentation of generalised vitiligo. Although immunomodulators,
such as corticosteroids, have been used both topically and systemically
over the past 3 decades for the treatment of disseminated vitiligo,
they are only suitable for the treatment of acrofacial and localised
forms because of adverse effects. Hence, new immunomodulatory
agents, such as calcineurin antagonists, have recently been introduced
as new promising tools to treat acquired hypopigmentary disorders.
However, all therapeutic approaches are hampered by the fact that
the pathophysiology of hypopigmentary disorders is still poorly
understood.

Clinical study of repigmentation patterns with
different treatment modalities and their correlation with speed
and stability of repigmentation in 352 vitiliginous patches.
Parsad D, Pandhi R, Dogra S, Kumar B.
Department of Dermatology, Postgraduate Institute of Medical Education
and Research, Chandigarh, India. dprs@satyam.net.in
Because the etiopathogenesis of depigmentation in vitiligo
is still obscure, the source of pigmentation in the repigmentating
lesion and its stability is also not fully known. Several authors
have shown on histopathology and electron microscopy predominantly
a perifollicular spread of pigment. The aim of this study was
to clinically assess the types of repigmentation patterns obtained
with different treatment modalities and their correlation with
speed and stability of repigmentation. A total of 125 patients
with vitiligo on treatment with psoralens (topical and systemic
psoralen-UVA [PUVA]), steroids (both topical and systemic), and
topical calcipotriol, alone or in combination were enrolled. Representative
lesions of vitiligo excluding mucosal sites were selected in each
patient and photographed at baseline. Repigmentation was assessed
and labeled as marginal, perifollicular, diffuse, or combined.
The preselected patches were evaluated at 3 months to assess the
speed of repigmentation. Retention of pigment (stability) was
noted at 6 months, after the stoppage of active treatment. Of
the 352 vitiligo patches selected, 194 (55%) showed predominant
perifollicular repigmentation, of which a majority (127; 65.5%)
were on systemic PUVA and 35 (18%) were on topical PUVA. Diffuse
pigmentation was observed in 98 patches (27.8%) of which 66 (67.3%)
were on topical steroids. Marginal repigmentation was seen in
15, of which the majority (80%) were on systemic PUVA and topical
calcipotriol. Of the 28 total lesions showing marked repigmentation
at 3 months, 22 lesions pigmented in a diffuse manner, 2 in a
perifollicular pattern, and 4 showed a combined type of repigmentation.
On follow-up, marginal repigmentation was the most stable (93.3%),
followed by perifollicular (91.7%) and combined type (84.4%).
Diffuse repigmentation was the least stable (78.5%). Psoralens
predominantly exhibit a perifollicular pattern of repigmentation
and steroids (topical/systemic), a diffuse type. The speed of
repigmentation is much faster when initial repigmentation is of
the diffuse type as compared with follicular repigmentation. The
marginal and perifollicular repigmentation is more stable than
the diffuse type of repigmentation.

A comparative study of punch grafting followed
by topical corticosteroid versus punch grafting followed by PUVA
therapy in stable vitiligo.
Barman KD, Khaitan BK, Verma KK.
Department of Dermatology and Venereology, All India Institute
of Medical Sciences, New Delhi, India.
BACKGROUND: Punch grafting followed by PUVA is an established
therapy for stable vitiligo, but punch grafting followed by topical
corticosteroid has never been evaluated. OBJECTIVE: The aim of
this study was to evaluate the efficacy of topical corticosteroid
in perigraft pigmentation and to compare it with perigraft pigmentation
after PUVA in patients with stable vitiligo. METHODS: Fifty patients
with stable vitiligo of various clinical types were subjected
to punch grafting. In a randomized case study, these patients
were divided into two groups: One group received post punch-grafting
PUVA (group I) and the other group post punch-grafting topical
application of fluocinolone acetonide 0.1% (group II). During
the follow-up period of 6 months, six patients were lost to follow-up,
and two patients were excluded from the study; 42 patients were
evaluated for pigment spread and side effects. RESULTS: In group
I, the average pigment spread was 6.38 mm, whereas in group II,
it was 6.94 mm, showing a slightly higher pigment spread in group
II, which was statistically not significant (P=0.301). There was
no difference in response to therapy in patients having segmental
vitiligo as compared with nonsegmental vitiligo. Cobblestoning,
depigmentation of the grafts, infection, and graft displacement
were the important side effects seen in some patients in both
the groups. CONCLUSION: The study shows that the pigment spread
with topical corticosteroid is comparable to that with PUVA. However,
the studies with long-term follow-up are required to establish
this. The advantages of topical corticosteroid are that its use
is easy, less cumbersome, cheaper, and more cost effective than
PUVA.

Vitiligo is an acquired idiopathic hypomelanotic disorder characterized
by circumscribed depigmented maculae. It can be treated in many
ways. The choice of therapy is individually adjusted depending
on various factors, such as the patient age, type and stage of
disease, and affected body site. Current treatment modalities
include psoralen with exposure to ultraviolet A (PUVA) radiation
therapy, narrow-band UVB therapy, topical corticosteroids, depigmentation
therapy with monobenzylether of hydroquinone, and surgical treatments
(minigrafting, thin split-thickness grafting, suction blister
grafting, micropigmentation). There are also some new treatment
modalities, such as 308-nm excimer laser, vitamin D analogues,
tacrolimus, depigmentation with Q-switched ruby laser, and grafting
of cultured melanocytes.

faika.cherif@voila.fr
We performed a prospective study to evaluate efficacy of the
combination of calcipotriol and psoralen plus ultraviolet A (PUVA)
in the treatment of vitiligo. Twenty-three patients with essentially
bilateral symmetrical lesions of vitiligo were included. Calcipotriol
(0.005 %) ointment was applied twice daily over the right side
of the body, and the other side was not treated. PUVA was performed
three times per week. All patients received at least forty five
sessions of PUVA. Patients were evaluated clinically and photographed
all fifteen weeks. At the fifteenth session, 69 percent of the
patients had minimal to moderate improvement on the calcipotriol
side compared to 52 percent on the PUVA-only side (p = 0.015).
At the forty-fifth session, 52 percent showed marked improvement
on the calcipotriol side compared to 30 percent on the PUVA-only
side (p = 0.13), with more intense repigmentation on calcipotriol-treated
areas. Treatment was well tolerated, and no adverse effect was
noted. This combination was an effective treatment for vitiligo,
especially in initiating repigmentation.

IL-38 Surgical treatment of vitiligo.
Naeyaert JM, Geel N, Ongenae K.
Ghent University Hospital, Department of Dermatology, Gent, Belgium.
Vitiligo is a common acquired disorder of pigmentation. Therapy
for active or stable, non-treated vitiligo is medical (local corticosteroids,
immunomodulators and vitamin D derivatives and systemic or topical
photo(chemo)therapy). Surgical treatment is suitable for stable
disease, resistant to medical therapy. The basic principle in
surgical grafting is to transplant autologous melanocytes from
a pigmented donor area to a depigmented acceptor area. Both tissue
and cellular grafts have been used with some success. We undertook
a randomized double blind placebo controlled study of autologous
non-cultured epidermal cells for repigmenting vitiligo patches
in order to assess the efficacy and safety of this technique and
to get insight into the mechanisms of repigmentation. Twenty-eight
patients with vitiligo, resistant to previous medical treatment,
were included. Thirty-three symmetrical, paired lesions were treated.
The donor area for the epidermal cells was the buttock area where
a thin split-thickness graft was harvested with a hand-held dermatome.
The sheet was trypsinized and resuspended in a low-calcium melanocyte
medium enriched with hyaluronic acid. Meanwhile, the acceptor
areas were anaesthesized with EMLA cream, and the epidermis was
abraded with a CO2 laser (Coherent). One of the paired lesions
received the full cellular suspension, the other the suspension
without cells. Repigmentation was measured at 3, 6 and 12 months
using digitalized image analysis. In 19 patients with stable vitiligo
according to anamnestic and clinical data, 70% repigmentation
was achieved in 55%, 57% and 77% of patients 3, 6 and 12 months
after treatment respectively. In a second group of 9 patients
clinical follow-up casted doubts on the stable nature of their
vitiligo. Percentages of repigmentation were 0% at all times in
this group. The pattern of repigmentation was diffuse, not perifollicular.
We conclude that transplantation of autologous epidermal cell
suspensions results in repigmentation of >70% in the majority
of patients with stable disease. Repigmentation is caused by the
transplanted cells, as a role of post-inflammatory pigmentation,
UV-induced pigmentation and spontaneous pigmentation is of minimal
importance.

IL-37 Lasers in pigmentary disorders.
Dierickx CC.
Visiting Lecturer, Harvard Medical School, Boston, MA, Consultant,
Department of Dermatology, Ghent University Hospital, Belgium;
Director Laser Clinic, Boom, Belgium.
A variety of lasers can be used to target melanin in the skin.
The fundamental principle behind laser treatment of cutaneous
pigmentation is selective destruction of undesired pigment with
minimal collateral damage. This destruction can be achieved by
the delivery of high energy at the absorptive wavelength of the
selected chromophore1. The approach with lasers for the treatment
of cutaneous pigmentation depends on the localization of the pigment,
(epidermal, dermal or mixed), the way it is packaged (intracellular
or extracellular) and the nature of the pigment. Short-pulsed
lasers, including the Q-switched ruby laser, the Q-switched Nd-YAG
laser, the Q-switched alexandrite laser and the 510 nm pulsed
pigment laser, as well as millisecond pigment lasers have been
utilized in the treatment of pigment disorders. Electron microscopic
evaluation has demonstrated that melanosome destruction is occurring
after treatment with the short pulsed lasers2 and melanocyte destruction
occurs after treatment with the millisecond lasers3. Among the
benign pigmented lesions which do react well are ephelifes (freckles)
pigmented actinic keratosis, nevus of Ota, nevus of Ito, and 'blue'
nevus. Varying results are obtained in so-called 'cafe au lait'-maculae,
congenital and acquired nevocellular nevi, nevus spilus and nevus
of Becker. Treatment of congenital and acquired nevi nevocellulares
is still controversial because of the possibility of incomplete
destruction of deeper situated nevi cells and the possibility
of masking. Hyperpigmentation like melasma and post-inflammatory
hyperpigmentation only show moderate reactions. One has to realise
that laser treatment itself can result in post-inflammatory hyperpigmentation.
Narrow-band UVB phototherapy has been shown to be a safe and effective
treatment for vitiligo, Recently, a 308 nm UVB excimer laser and
a filtered UV source to treat localized vitiligo have been developed.
The laser is a XTRACTM XeCl excimer laser (PhotoMedex, Radnor
PA) and the filtered UV source is the B Clear (Lumenis). UV lesion-directed
treatment for localized vitiligo could have considerable advantages
over conventional UVB treatment, including fewer treatments, lower
cumulative doses resulting in a greater risk/benefit ratio4.

OBJECTIVE: To induce complete and reproducible repigmentation
of large "stable" vitiligo lesions by means of autologous
cultured epidermal grafts using a rapid, simple, and minimally
invasive surgical procedure. DESIGN: Achromic epidermis was removed
by means of appropriately settled erbium:YAG laser, and autologous
epidermal grafts were applied onto the recipient bed. Melanocyte
content was evaluated by dopa reaction. The percentage of repigmentation
was calculated using a semiautomatic image analysis system. SETTING:
A biosafety level 3-type cell culture facility, a surgical ambulatory
department, and a dermatological department in a hospital. PATIENTS:
Twenty-one patients with different types of vitiligo were admitted
to the study and treated with autologous cultured epidermal grafts.
Inclusion criteria were failure of at least 2 standard medical
approaches; no therapy for at least 12 months; no progression
of old lesions or appearance of new lesions; no Koebner phenomenon
within the past 18 months; and no autoimmune disorders. RESULTS:
The average percentage of repigmentation in 21 patients was 75.9%
(1759.7 cm2 repigmented/2315.8 cm2 transplanted). Three patients
showed a reactivation of their vitiligo and did not show repigmentation.
The remaining 18 patients, with 43 distinct lesions, showed an
average percentage of repigmentation of 90% (1759.7 cm2 repigmented/1953.4
cm2 transplanted). CONCLUSIONS: Under appropriate conditions,
cultured epidermal grafts induce complete repigmentation of stable
vitiligo lesions. Erbium:YAG laser surgery can supply a fast and
precise tool for disepithelialization, hence allowing treatment
of large vitiligo lesions during a single surgical operation.

Division of Dermatology, Department of Medicine, Ramathibodi Hospital,
Mahidol University, Bangkok, Thailand. ranrj@mahidol.ac.th
BACKGROUND: Narrowband ultraviolet B (NBUVB) has recently been
reported to be effective therapy for vitiligo. However, reports
on its efficacy in recalcitrant vitiligo are lacking. OBJECTIVE:
Our objective was to assess the efficacy of NBUVB in patients
with vitiligo who did not respond to either topical therapy or
oral psoralen plus ultraviolet A (PUVA). METHOD: This was a retrospective
analysis of patients with vitiligo who were treated with NBUVB
from February 1998 to January 2001. They received NBUVB treatment
2 times per week, with an initial dose of 100 mJ/cm(2). The dose
was increased by 10% to 20% per treatment for 20 treatments. The
dose was then increased by 2% to 5% per treatment until 50% repigmentation
was observed or persistent erythema developed. The treatment was
continued until maximum repigmentation was achieved. The treatment
was terminated if the patient showed less than 25% improvement
after 40 to 50 exposures. RESULTS: There were 60 patients: 22
men and 38 women, aged 11 to 61 years. The mean duration of vitiligo
was 8.2 +/- 7.1 years. There were 53 cases of generalized and
7 cases of localized vitiligo. The lesions covered from less than
5% to 50% of body surface. Twenty-five patients were skin type
III, 33 patients were skin type IV, and 2 patients were skin type
V. Every case had been previously treated with topical steroid
with or without topical psoralen with solar light exposure. Thirty-six
patients (60%) had been treated with oral PUVA before NBUVB therapy.
After NBUVB treatment, 25 of 60 patients (42%) achieved more than
50% repigmentation on face, trunk, arms, and legs. However, hand
and foot lesions showed less than 25% repigmentation in all cases.
There was no significant difference between the responders and
nonresponders in age, sex, duration of diseases, and skin type.
The response rate of patients who had not been previously treated
with PUVA was significantly higher than that of patients who had
been previously treated with PUVA (67% vs 36%, P =.003). CONCLUSION:
This retrospective, open study demonstrated that NBUVB therapy
was effective in 42% of Asian patients with recalcitrant vitiligo
without serious side effect. The only clinical parameter that
could differentiate nonresponders from responders was previous
exposure to PUVA.

308-nm excimer laser for the treatment of localized
vitiligo.
Taneja A, Trehan M, Taylor CR.
Department of Dermatology, Massachusetts General Hospital, Harvard
Medical School, Boston, MA, USA.
BACKGROUND AND OBJECTIVE: Vitiligo is commonly treated with
PUVA, and more recently, narrow-band UVB (NBUVB) phototherapy.
Given the proximity of the wavelengths of NBUVB (311 nm) and the
excimer laser (308 nm), we undertook a clinical trial to test
the efficacy of this device. METHODS: Twice-weekly 308-nm UV-B
radiation was given to selected vitiligo lesions for a maximum
of 60 treatments. These lesions had been unsuccessfully treated
previously with at least one other method of treatment. Initial
doses were 100 mJ/cm2 with increments of 10-25%. Improvement was
assessed on a visual scale via serial photographs. RESULTS: Subjects
tolerated the treatment well. Improvement varied with body site.
After 60 treatments, lesions on the hands and feet showed grade
2 improvement in 2/10 subjects and grade 1 in 8/10. For the axillae,
there was grade 4 improvement in 1/3 subjects and grade 2 improvement
in 2/3 by treatment 60. The face demonstrated the most rapid repigmentation
with grade 4 repigmentation seen in 3/5 subjects by 40 treatments
and grade 3 in 2/5 by 30 treatments. There were no adverse effects.
CONCLUSIONS: The user-friendly 308-nm excimer laser allows targeted
treatments of localized vitiligo.

pruritus, and inflammatory dermatoses.
Samson Yashar S, Gielczyk R, Scherschun L, Lim HW.
Department of Dermatology, Henry Ford Health System, Detroit,
MI 48202, USA.
BACKGROUND: Narrow-band ultraviolet B (NB-UVB) therapy has
been used successfully for the treatment of inflammatory and pigmentary
skin disorders including atopic dermatitis, psoriasis, mycosis
fungoides, polymorphous light eruption, and vitiligo. METHODS:
This is a retrospective review of the treatment outcomes of 117
consecutive patients with vitiligo, pruritus, and other inflammatory
dermatoses, excluding those with psoriasis and CTCL, who were
treated with NB-UVB between 1998 and 2001 at our institution.
RESULTS: Approximately 80% of all patients showed improvement
in their condition. NB-UVB phototherapy was well tolerated, with
no serious adverse effects. In patients with vitiligo, 6.4% had
an abnormal thyroid-stimulating hormone level and 6.5% had anemia.
CONCLUSION: NB-UVB may be considered as a viable therapeutic option
in the treatment of vitiligo, pruritus, and other inflammatory
dermatoses. Long-term adverse effects and cost-benefit analysis
of NB-UVB therapy compared to other treatment modalities remain
to be determined.

OBJECTIVE: To observe the therapeutic effect of Xiaobai Mixture
(XBM) in treating vitiligo. METHODS: Seventy-four patients with
vitiligo were randomly divided into the XBM group treated with
XBM and the control group treated with 8-MOP. The therapeutic
effect, nail-fold microcirculation, plasma endothelin-1, serum
immunoglobulin were observed and compared. RESULTS: The therapeutic
effect of XBM was better than that of 8-MOP (P < 0.05). XBM
could also obviously improve the nail-fold microcirculation, elevate
the plasma endothelin-1 level and lower the serum IgG (P <
0.01). CONCLUSION: XBM has superiority in treating vitiligo.

Open trial of topical tacalcitol [1 alpha 24(OH)2D3]
and solar irradiation for vitiligo vulgaris: upregulation of c-Kit
mRNA by cultured melanocytes.

Vitiligo vulgaris is a common skin disease, however some cases
show poor clinical responses to topical steroid ointment or PUVA
therapy. Such regimens are generally avoided in the treatment
of facial lesions or in pediatric cases because of the undesirable
side effects. To confirm the excellent response to combination
therapy with topical vitamin D3 ointment and solar irradiation
for vitiligo achieved in the initial patients, we conducted an
open trial on other patients, most of whom had poor clinical responses
to the prior therapies. Fifteen patients (9 men and 6 women) with
vitiligo vulgaris were enrolled in this study. Each patient was
instructed to sunbathe for 30 minutes within 1 hour after topical
application of the tacalcitol [1 alpha 24(OH)(2)D(3)] ointment
or cream to the skin lesions every day. Six of 15 patients showed
a fair and excellent clinical response to the combination therapy
(more than 30% clearance of the vitiligo). The clinical effect
was more apparent in patients with a history of less than 5 years
of vitiligo (4 of 6 cases) in contrast to those with a history
of more than 5 years (2 of 9 cases). In vitro experiments revealed
that tacalcitol upregulated the expression of c-Kit mRNA by melanocytes
irradiated with linear polarized infrared, UVA or short period
solar irradiation. These results suggest that combination therapy
with topical vitamin D(3) ointment and solar irradiation can be

Epidermal grafting in vitiligo: influence of age,
site of lesion, and type of disease on outcome.
Gupta S, Kumar B.
Department of Dermatology, Venereology, and Leprology, Postgraduate
Institute of Medical Education and Research, Chandigarh, India.
BACKGROUND: The success of suction blister epidermal grafting
may be influenced by various factors, all of which have not been
studied to date. OBJECTIVE: We sought to determine the influence
of age of the patient, site of vitiligo patch, and type of disease
on the outcome of the procedure in our patients and in the cumulative
data derived from literature analysis. METHODS: This was a retrospective,
uncontrolled case series and literature review of suction blister
epidermal grafting in patients with stable and recalcitrant vitiligo.
All published studies of suction blister epidermal grafting in
vitiligo involving 10 or more patients were included in the literature
analysis. RESULTS: The procedure was performed in 143 patients.
However, sufficient length (6 postoperative months) of follow-up
was available in only 117 patients, and only these patients were
included for analysis. Only limited information was available
about various factors in the majority of published studies. The
success rates for generalized and segmental/focal disease in this
study were 53% (confidence interval [CI] 42-64) and 91% (CI 81-100),
respectively (P <.001), and in the literature, 61% (CI 46-76)
and 88% (CI 82-94), respectively (P <.01). The success rates
in patients aged < 20 years and >or= 20 years in this study
were 82% (CI 67-97) and 58% (CI 48-68), respectively (P <.05),
and in the literature, 100% and 66% (CI 56-76), respectively (P
<.05). There was no significant difference in the success rates
achieved on different body sites in this study and in the screened
literature. Among adverse reactions, hyperpigmentation in 32%
(CI 24-40) and 17% (CI 14-20), infection in 6% (CI 2-10) and 0%,
and contact dermatitis in 1% (CI 0-3) and 1% (CI 0-2) of patients
were observed in this study and in the analyzed literature, respectively.
CONCLUSIONS: The results were significantly better in segmental/focal
vitiligo than in the generalized type, and in individuals <
20 years of age. However, unlike in medical therapies, localization
of the vitiligo patch did not influence the treatment outcome
significantly.

[Research of magnetism light compound therapy
in clinical application]
[Article in Chinese]
Liu Z, Sun C, Zhang W, Mao J, Yan Y, Fu C.
Second People's Hospital of Jianyang, Jianyang 641421.
This study is aimed to evaluate the clinical application of
the millimeter wave and magnetism light compound therapy. The
EHF-98B MMW. RL compound therapy apparatus made in the University
of Electronic Technology(Chengdu) was used in 171 patients. The
superficial, skin lesions or the visceral reflected skin regions
(acupoints) were directly exposed to the light from the apparatus.
All the cases were divided into five groups, namely skin mucosa
superficial lesions, trauma of the bone and joint soft tissue,
surgical incision, ENT infections, and rare intricate diseases.
The therapeutic effects observed in the groups were analyzed and
evaluated by means of 4 levels. As for the 171 patients, the cure
rate was 42.7% (73 patients), the effective rate 25.1%(43 patients),
the improvement rate 31%(53 patients), and no effect constituted
1.2%(2 patients). The total effective rate was 98.8%. This therapy
was especially effective for treating chronic cervicitis, cervical
erosion, soft tissue trauma, surgical incision. Also it was effective
for treating some rare intricate diseases, e.g. sterility, vitiligo,
Behcet disease. So the millimeter wave and magnetism light compound
therapy may find wide clinical applications.

Medicine, College of Medicine, University of South Florida, Tampa,
Florida.
Biofeedback can improve cutaneous problems that have an autonomic
nervous system component. Examples include biofeedback of galvanic
skin resistance (GSR) for hyperhidrosis and biofeedback of skin
temperature for Raynaud's disease. Hypnosis may enhance the effects
obtained by biofeedback. Cognitive-behavioral methods may resolve
dysfunctional thought patterns (cognitive) or actions (behavioral)
that damage the skin or interfere with dermatologic therapy. Responsive
diseases include acne excoriee, atopic dermatitis, factitious
cheilitis, hyperhidrosis, lichen simplex chronicus, needle phobia,
neurodermatitis, onychotillomania, prurigo nodularis, trichotillomania,
and urticaria. Hypnosis can facilitate aversive therapy and enhance
desensitization and other cognitive-behavioral methods. Hypnosis
may improve or resolve numerous dermatoses. Examples include acne
excoriee, alopecia areata, atopic dermatitis, congenital ichthyosiform
erythroderma, dyshidrotic dermatitis, erythromelalgia, furuncles,
glossodynia, herpes simplex, hyperhidrosis, ichthyosis vulgaris,
lichen planus, neurodermatitis, nummular dermatitis, postherpetic
neuralgia, pruritus, psoriasis, rosacea, trichotillomania, urticaria,
verruca vulgaris, and vitiligo. Hypnosis can also reduce the anxiety
and pain associated with dermatologic procedures.

From medical herbalism to phytotherapy in dermatology:
back to the future.
Dattner AM.
Integrative Medicine and Dermatology, New Rochelle, New York.
Plant-based therapeutic preparations are cyclically returning
to complement dermatologic therapy. They serve as therapeutic
alternatives, safer choices, or in some cases, as the only effective
treatment. Folk medicine tradition provides different indicators
for use than the medical disease model. Advantages of multiple
synergistic components of crude extracts are discussed, as well
as herbs already used in dermatology. Bitter digestive stimulants
are used for vitiligo. Bioflavinoids from buckwheat and horse
chestnut are used for varicose veins, and silymarin is used for
liver protection. Gotu kola and sarsaparilla are used for inflammatory
skin conditions. Oregon grape root has synergistic antibacterial,
anti-inflammatory, and bile-stimulating properties which make
the crude extract useful in acne. Philosophical differences in
herbology compared to medicine exist in the application of science
toward improving elimination and strengthening the host as opposed
to destroying the vector or manifestation of the disease.

Effectiveness of oral Ginkgo biloba in treating
limited, slowly spreading vitiligo.
Parsad D, Pandhi R, Juneja A.
Department of Dermatology, Postgraduate Institute of Medical Education
and Research, Chandigarh, India. dprs@satyam.net.in
For effective treatment of vitiligo, it is as important to
arrest the progression of the disease as it is to induce repigmentation.
Recently, oxidative stress has been shown to play an important
role in the pathogenesis of vitiligo. Ginkgo biloba extract has
been shown to have antioxidant and immunomodulatory properties.
In a double-blind placebo-controlled trial, we evaluated the efficacy
of G. biloba extract in controlling the activity of the disease
process in patients with limited and slow-spreading vitiligo and
in inducing repigmentation of vitiliginous areas. Fifty-two patients
were assigned to two treatment groups (A and B) in a double-blind
fashion, but only 47 patients could be evaluated, because one
patient in group A and four patients in group B withdrew for reasons
unrelated to the study. Patients in group A were given G. biloba
extract 40 mg three times daily whereas patients in group B received
placebo in similar doses. A statistically significant cessation
of active progression of depigmentation was noted in patients
treated with G. biloba (P = 0.006). Marked to complete repigmentation
was seen in 10 patients in group A, whereas only two patients
in group B showed similar repigmentation. The G. biloba extract
was well tolerated. G. biloba extract seems to be a simple, safe
and fairly effective therapy for arresting the progression of
the disease.

Is the combination of calcipotriol and PUVA effective
in vitiligo?
Baysal V, Yildirim M, Erel A, Kesici D.
University of Suleyman Demirel, School of Medicine, Department
of Dermatology, Isparta, Turkey.
OBJECTIVE: The objective was to compare the effectiveness of
psoralen plus ultraviolet A (PUVA) and the combination of PUVA
and topical calcipotriol in the treatment of vitiligo. BACKGROUND:
There are several reports on the response rate of patients with
vitiligo treated with the combination of PUVA and calcipotriol
or calcipotriol alone. SUBJECTS AND METHODS: Twenty-two patients
with generalized vitiligo were taken into the study. PUVA treatment
was applied on a twice-weekly schedule. Calcipotriol cream was
applied to one of the two symmetrical lesions of each patient
twice daily. RESULTS: Our results showed that the addition of
topical calcipotriol to PUVA treatment did not lead to a significant
increase in response rate of patients with vitiligo compared with
PUVA treatment alone.

OBJECTIVE: To assess the safety and efficacy of topical 0.1%
tacrolimus vs 0.05% clobetasol propionate. DESIGN: Randomized
double-blind trial. SETTING: Department of Dermatology, Hospital
Central Dr Ignacio Morones Prieto, San Luis Potosi, Mexico. PARTICIPANTS:
From 20 children with vitiligo, 2 symmetrical lesions of about
the same size and evolution time were selected. They were devoid
of any topical or systemic therapy for 2 months prior to inclusion.Interventions
Treatment with topical tacrolimus and clobetasol for a 2-month
period. MAIN OUTCOMES MEASURES: The grade of repigmentation was
evaluated by color slides at baseline and again at every 2-week
visit. The slides were analyzed by 2 clinicians unrelated to the
study and by a morphometric digitalized computer program. Characteristics
of pigment, time of response, symptoms, telangiectasias, and atrophy
were evaluated every 2 weeks. RESULTS: Eighteen (90%) of the 20
patients experienced some repigmentation. The mean percentage
of repigmentation was 49.3% for clobetasol and 41.3% for tacrolimus.
Lesions in 3 patients using clobetasol presented atrophy, and
2 lesions incurred telangiectasias; tacrolimus caused a burning
sensation in 2 lesions. CONCLUSIONS: Tacrolimus proved almost
as effective as clobetasol propionate to restore skin color in
lesions of vitiligo in children. Because it does not produce atrophy
or other adverse effects, tacrolimus may be very useful for younger
patients and for sensitive areas of the skin such as eyelids,
and it should be considered in other skin disorders currently
treated with topical steroids for prolonged periods.

Various surgical methods have been used in the treatment of
small stable vitiliginous areas, but there is no established surgical
approach for larger vitiligo areas and therapy-resistant anatomic
sites, such as the hands. Two years ago, we successfully treated
large burn scar depigmentation areas at different anatomic sites
using carbon dioxide laser resurfacing and thin (0.2 to 0.3 mm)
skin grafting. The purpose of this study was to investigate the
effectiveness of our method in treating large, stable, and recalcitrant
vitiligo areas. Thirteen anatomic sites of seven male patients,
whose ages ranged from 20 to 22 years, were treated. The locations
of the treated areas were as follows: seven areas on the dorsum
of the hands, two areas on the forearms, two areas in the pretibial
region, one area on the lateral thigh, and one area in the presternal
region. The surface area of treated vitiligo sites ranged from
0.5 to 6 percent of total body surface area (mean, 2.5 percent).
Skin graft take was excellent in all patients except for one.
The follow-up period for these patients ranged from 6 to 18 months,
with an average follow-up period of 14 months. Early and complete
repigmentation was achieved and the color match was good or excellent
in all patients. No depigmentation occurred again in the treated
areas or graft donor sites. In conclusion, with careful patient
selection and delicate surgical technique, our method was effective
in treating large areas of vitiligo over the extremities and dorsum
of hands, which were refractory to other therapies and could not
be hidden.

Narrow-band UV-B micro-phototherapy: a new treatment
for vitiligo.
Menchini G, Tsoureli-Nikita E, Hercogova J.
Department of Dermosciences, University of Florence, Florence,
Italy. g.menchini@dermatologia.it
BACKGROUND: Vitiligo is a common, acquired, often familial,
melanocytopenic disorder with focal depigmentation of the skin.
There are several new treatments, that appear to have higher success
rates than previous therapies for the treatment of vitiligo. Among
these, the most promising one appears to be narrow-band UV-B therapy.
OBJECTIVE: The aim of this open study is to evaluate the efficacy
of the BIOSKIN micro-phototherapy in the treatment of vitiligo
in 734 patients. SUBJECTS AND METHODS: Seven hundred and thirty-four
individuals affected by vitiligo (segmental and non-segmental)
were treated for 12 months with a new device called BIOSKIN that
can produce a focused beam of narrow UV-B (microphoto-therapy)
on vitiligo patches only. Photographs of the subjects were taken
at the beginning of the therapy and every month thereafter for
12 months. The response to treatment was estimated in two comparable
photographs using planimetry. The duration of the clinical study
was of 2 years and 8 months. At the end of this period 734 patients
had received each a mean of 24 sessions of treatment during a
period of 12 months. RESULTS: Five hundred and ten subjects (69.48%)
of the 734 achieved normal pigmentation on more than 75% of the
treated areas. In particular, 112 of these were totally repigmented.
One hundred and fifty-five (21.12%) individuals achieved 50-75%
pigmentation of the treated areas, and 69 (9.40%) showed less
than 50% repigmentation. No patients showed acute or chronic relevant
adverse effects. CONCLUSION: BIOSKIN UV-B microphototherapy seems
highly effective in restoring pigmentation in patients affected
by vitiligo. As no side-effects have been observed, this could
represent the treatment of choice for vitiligo limited to less
than 30% of the skin surface.

Photo(chemo) therapy for vitiligo.
Roelandts R.
Photodermatology Unit, University Hospital St Raphael, Kapucijnenvoer

Vitiligo has always been difficult to treat. Several modes
of treatment are available, but the therapeutic effect varies
greatly, and rarely does one achieve complete repigmentation.
One of the most efficient treatment methods is photo(chemo) therapy.
Already in ancient Egypt, vitiligo lesions were treated with extracts
of the Ammi maius plant followed by exposure to the sun. This
principle is at the basis of the photochemotherapy or PUVA therapy,
whereby UVA irradiations are given 2 h after administration of
8-methoxypsoralen, a photosensitizer. Another efficient treatment
form is UVB phototherapy, particularly narrow-band UVB. This not
only gives good therapeutic results but also has the advantage
of eliminating the need for a photosensitizer. All these treatments
must be applied for many months to be efficient. They can also
be combined with various surgical skin-grafting techniques. A
newer approach is targeted UVB phototherapy, whereby xenon-chloride
lasers or monochromatic excimer light is used.

Melanocyte-keratinocyte cell transplantation for
stable vitiligo.
Mulekar SV.
Noble Clinic, Pune, India. dr_mulekar@vsnl.com
BACKGROUND: Vitiligo is a common disorder with a worldwide
prevalence of 1-2%. In India the psychological and social impact
of the disease is significant and is detrimental to patients.
OBJECTIVE: To evaluate the usefulness of epidermal cell transplantation
in the treatment of vitiligo. METHODS: A simpler and modified
method based on that of Olsson and Juhlin has been used. It utilizes
a shave biopsy skin sample of up to one-tenth the size of the
recipient area. The skin sample is incubated, the cells mechanically
separated using trypsin EDTA solution, and then centrifuged to
prepare a suspension. The cell suspension is then applied to the
derm-abraded depigmented skin area and collagen dressing is applied
to keep it in place. RESULTS: One hundred and twenty-two patients
with generalized vitiligo, 43 with segmental and 19 with focal
vitiligo were treated and observed for a period of 1 year. In
the generalized vitiligo group 65 (53%) showed excellent pigmentation,
10 (8%) showed good pigmentation, 11 (9%) showed fair pigmentation
and 28 (23%) patients showed poor pigmentation. Eight (7%) patients
did not follow up. Thirty-six (84%), five (12%) and two (4%) patients
showed excellent, good and poor pigmentation, respectively, in
the segmental vitiligo group. Thirteen (69%) and five (26%) patients
showed excellent and poor results, respectively, in the focal
vitiligo group. One (5%) patient did not appear for follow up.
Recurrence was observed in 15 patents. CONCLUSION: This surgical
treatment gives its best results in segmental and focal vitiligo,
even with large affected areas, and in at least 50% of patients
with generalized vitiligo, thus improving their appearance.

Tacrolimus ointment 0.1% produces repigmentation
in patients with vitiligo: results of a prospective patient series.
Tanghetti EA.
Center for Dermatology and Laser Surgery, Sacramento, California,
USA. et@mgci.com
The cause of the selective melanocyte destruction in vitiligo
may be due to an autoimmune disorder. A series of 15 patients
with vitiligo were treated with a topical immunomodulator, tacrolimus
ointment 0.1%, twice daily for a minimum of 45 days. Thirteen
patients (87%) experienced at least partial repigmentation, and
3 of those patients had greater than 75% repigmentation. Patients
with the greatest treatment response likely benefited from concomitant
natural sunlight exposure. Further studies investigating the safety
and efficacy of tacrolimus ointment either as monotherapy or in
combination with other therapeutic measures are warranted.

This paper presents the results of a pilot clinical trial study,
conducted on 11 patients with stable vitiligo at the vitiligo
outpatient clinic of The Unicamp University Hospital, between
March 2000 and December 2001. This study was in accordance with
the ethical standards of the Institutional Review Board. The patients
were concomitantly treated with four different types of surgical
techniques in 44 areas randomly chosen. There was a 90-day follow-up
period. The following treatments were carried out: only cryotherapeutic
treatment (OC); cryotherapy plus melanocyte culture medium (CM);
cryotherapy plus transplantation of non-cultured melanocytes and
keratinocytes (KM); and cryotherapy plus transplantation of cultured
melanocytes (CC). The appearance of repigmentation and its evolution
were followed all along the treatments. In the case of OC and
CM no repigmentation occurred. Progressive repigmentation was
observed over a period of 90 days in the case of KM and CC. In
these two groups there was a significant reduction in the achromic
areas during this time but no significant difference was found
between the two treatments.

Helium-neon laser irradiation stimulates migration
and proliferation in melanocytes and induces repigmentation in
segmental-type vitiligo.

Low-energy helium-neon lasers (632.8 nm) have been employed
in a variety of clinical treatments including vitiligo management.
Light-mediated reaction to low-energy laser irradiation is referred
to as biostimulation rather than a thermal effect. This study
sought to determine the theoretical basis and clinical evidence
for the effectiveness of helium-neon lasers in treating vitiligo.
Cultured keratinocytes and fibroblasts were irradiated with 0.5-1.5
J per cm2 helium-neon laser radiation. The effects of the helium-neon
laser on melanocyte growth and proliferation were investigated.
The results of this in vitro study revealed a significant increase
in basic fibroblast growth factor release from both keratinocytes
and fibroblasts and a significant increase in nerve growth factor
release from keratinocytes. Medium from helium-neon laser irradiated
keratinocytes stimulated [3H]thymidine uptake and proliferation
of cultured melanocytes. Furthermore, melanocyte migration was
enhanced either directly by helium-neon laser irradiation or indirectly
by the medium derived from helium-neon laser treated keratinocytes.
Thirty patients with segmental-type vitiligo on the head and/or
neck were enrolled in this study. Helium-neon laser light was
administered locally at 3.0 J per cm2 with point stimulation once
or twice weekly. The percentage of repigmented area was used for
clinical evaluation of effectiveness. After an average of 16 treatment
sessions, initial repigmentation was noticed. Marked repigmentation
(>50%) was observed in 60% of patients with successive treatments.
Basic fibroblast growth factor is a putative melanocyte growth
factor, whereas nerve growth factor is a paracrine factor for
melanocyte survival in the skin. Both nerve growth factor and
basic fibroblast growth factor stimulate melanocyte migration.
It is reasonable to propose that helium-neon laser irradiation
clearly stimulates melanocyte migration and proliferation and
mitogen release for melanocyte growth and may also rescue damaged
melanocytes, therefore providing a microenvironment for inducing
repigmentation in vitiligo.

Melanocyte destruction and repigmentation in vitiligo:
a model for nerve cell damage and regrowth.
Yu HS.
Department of Dermatology, College of Medicine, Kaohsiung Medical
University, Kaohsiung, Taiwan, ROC.
Melanocytes (MCs) are melanin-producing cells of the skin that
are derived from neural crest cells. Vitiligo vulgaris is a common
depigmentation disorder resulting from the destruction of functional
MCs in the affected skin. The three prevailing pathomechanisms
of vitiligo are the immune hypothesis, the neural hypothesis and
the autocytotoxic hypothesis. None of these mechanisms has been
conclusively proven. Melanoblasts (MBs) in the outer root sheath
of the hair follicles are the reservoir cells for repigmentation.
Recovery from vitiligo is initiated by activation and proliferation
of these MBs, followed by upward migration to the nearby epidermis
that forms perifollicular pigmentation islands. Migration, proliferation
and differentiation of MCs and MBs are regulated by keratinocyte-derived
factors and some coat color genes. Any therapy for vitiligo must
explain not only the repopulation of MCs but also their functional
development. In patients with vitiligo, MCs are destroyed in the
skin, the eyes, and possibly the ears. However, the concept of
vitiligo as a systemic disease will be clearly established only
when the mechanisms involved in vitiligo are identified. Recent
advances in the fields of neural crest cell culture and molecular
genetics have opened new perspectives in the understanding of
vitiligo. Not only will this result in better treatments for vitiligo
patients, but possibly will also provide a key to triggering nerve
cell regrowth in other nervous diseases. Copyright 2002 National

Treatment of vitiligo vulgaris with narrow band
UVB (311 nm) for one year and the effect of addition of folic
acid and vitamin B12.

The Netherlands. M.Tjioe@derma.azn.nl
Narrow band UVB is succeeding psoralen and UVA irradiation
as the main treatment of vitiligo vulgaris in several European
countries. Vitamin B12 and folic acid deficiency in some vitiligo
patients has prompted researchers to investigate the efficacy
of these vitamins in the treatment of vitiligo. In the present
controlled study we investigated the value of narrow band UVB
phototherapy in the treatment of vitiligo and the possible additive
effect of vitamin B12 and folic acid. Twenty-seven patients with
long-term stable vitiligo were included and randomized in a "UVB
only" (UVB) or "UVB combined with vitamin B12 and folic
acid" (UVB+) group. Patients were irradiated thrice weekly
for one year, whilst repigmentation was carefully monitored. In
92% (25/27) of the patients up to 100% repigmentation was seen.
Repigmentation was notable in lesions on the face, neck and throat,
lower arm, chest, back and lower legs, whilst repigmentation on
the hands, wrists, feet and ankles proved to be minimal. Maximum
repigmentation rates did not differ significantly between the
UVB group and the UVB+ group. Our study reconfirms that narrow
band UVB phototherapy is an effective treatment for vitiligo and
shows that co-treatment with vitamin B12 and folic acid does not
improve the outcome of treatment of vitiligo with narrow band
UVB phototherapy.

Long-term follow-up of leucoderma patients treated
with transplants of autologous cultured melanocytes, ultrathin
epidermal sheets and basal cell layer suspension.
Olsson MJ, Juhlin L.
Department of Medical Sciences, Section of Dermatology and Venereology,
University Hospital, SE-751 85 Uppsala, Sweden. mats.olsson@medsci.uu.se
BACKGROUND: In vitiligo and piebaldism the lack of melanin
in the epidermis is due to the fact that melanocytes are missing.
The patients suffer psychologically and the white areas have lost
the part of the skin barrier protection normally provided by the
melanocytes. Medical treatments are ineffective in many of the
patients, and surgical methods have therefore been developed.
OBJECTIVES: It is important to investigate the long-term results
and factors that might influence the outcome of melanocyte transplantations
in order to form a basis for guidance in the selection of patients
who will benefit most from the treatments. METHODS: A follow-up
of 132 patients who had been treated by transplantation on 176
occasions in total, 1-7 years previously, was carried out by questionnaires
and clinical examinations. We investigated the responses in five
types of leucoderma to three different transplantation methods:
autologous cultured melanocytes, ultrathin epidermal sheets and
basal layer cell suspension. RESULTS: Stable types of leucoderma,
i.e. segmental vitiligo and piebaldism, responded in most cases
with 100% repigmentation, regardless of the surgical method used.
For these types of leucoderma surgery seems to be the method of
choice. The largest group, vitiligo vulgaris, was thoroughly scrutinized
and three statistical models were used to analyse the data. The
ultrathin epidermal sheet method gave somewhat better overall
results, but was the method that gave the worst outcome in knee
and elbow areas, emphasizing the importance of the right choice
of method depending on the anatomical location to be treated.
Irrespective of the method, fingers and elbows were the most difficult
areas to repigment. The trunk and the arms and legs (not including
elbows and knees) responded best. Patients with increasing and/or
extensive vitiligo vulgaris more often showed incomplete repigmentation.
They also had a lower chance of retaining their repigmentation
compared with those with less extensive vitiligo. Patients in
whom untreated white lesions had increased in recent years tended
to respond less well to transplantation compared with patients
with unchanged or decreased lesions. Within the vitiligo vulgaris
group, patients with short disease duration or with small total
vitiligo area responded best to transplantation. The subgroup
of vitiligo vulgaris patients with hypothyroidism tend to respond
less well to the transplantation and they were generally older
at vitiligo onset. This information is of great importance for
the selection of patients and when informing about the chances
of improvement after transplantation. Slight hyperpigmentation
was common, especially when ultrathin epidermal sheets had been
used. No scars or indurations were seen in treated areas. CONCLUSIONS:
Transplantations are the methods of choice in stable types of
leucoderma. Progressive, widespread vitiligo vulgaris should never
be selected for transplantation.

Approaches to repigmentation of vitiligo skin:
new treatment with ultrasonic abrasion, seed-grafting and psoralen
plus ultraviolet A therapy.

Vitiligo vulgaris is a common disease throughout the world
although its pathogenesis is not yet known. The most frequent
treatment used for vitiligo is PUVA (psoralen plus ultraviolet
A) and topical steroids but against stable refractory vitiligo,
various other surgical techniques have been developed such as
autografting, epidermal grafting with suction blisters, epithelial
sheet grafting, and transplantation of cultured melanocytes. We
have discovered a new method using ultrasonic abrasion, seed-grafting
and PUVA therapy. The ultrasonic surgical aspirator abrades only
the epidermis of recipient sites. This easily and safely removes
only the epidermis, even on spotty lesions or intricate regions
which are difficult to remove using a conventional motor-driven
grinder or liquid nitrogen. Epidermal seed-grafting can cover
more area than sheet-grafting, and subsequent PUVA treatment can
enlarge the area of pigmentation with coalescence of adjacent
grafts. In this article, we provide a general overview of the
current surgical therapies including our method for treating stable
refractory vitiligo.

BACKGROUND: Low catalase levels and cellular vacuolation in
the epidermis of patients with vitiligo support major oxidative
stress in this compartment. There is now in vivo evidence for
increased epidermal hydrogen peroxide (H(2)O(2)) accumulation
in this patient group by utilizing noninvasive Fourier Transform
Raman spectroscopy (FT Raman). Epidermal H(2)O(2) can be removed
with a topical application of narrow band UVB activated pseudocatalase
cream (PC-KUS). (Mn/EDTA-bicarbonate complex, patent No. EPO 58471
1 A), yielding initiation of repigmentation. Dead Sea climatotherapy
is another successful treatment modality for vitiligo, but the
mode of action has escaped definition so far. METHODS: Epidermal
hydrogen peroxide (H(2)O(2)) was assessed in vivo before and after
21 days treatment at the Dead Sea using noninvasive Fourier-Transform
Raman spectroscopy. The effectiveness of repigmentation was followed
in 59 patients with vitiligo by comparing Dead Sea climatotherapy
alone with the combination of Dead Sea climatotherapy/pseudocatalase
cream (PC-KUS) as well as Dead Sea climatotherapy/placebo cream.
Clinical repigmentation was documented by standardized black/white
photography using non-UV coated bulbs as flashlight and by color
photography. RESULTS: This study on 59 patients who had vitiligo
for an average time of 17 years (range 3-53 years) confirmed in
vivo H(2)O(2) accumulation in mM concentrations in the epidermis
of untreated patients. Furthermore, we demonstrated a pseudocatalase
activity after 15 min of Dead Sea bathing, but the decrease of
epidermal H(2)O(2) levels was significantly less compared to narrowband
UVB activated pseudocatalase cream (PC-KUS). Initiation of repigmentation
was already observed between day 10 and day 16 after a combination
of Dead Sea climatotherapy/pseudocatalase cream compared to conventional
pseudocatalase monotherapy (8-14 weeks) and Dead Sea climatotherapy
alone (5-6 weeks). CONCLUSION: The results of this study show
a significantly faster initiation of repigmentation in vitiligo
after a combination of short-term climatotherapy (21 days) at
the Dead Sea in combination with a pseudocatalase cream (PC-KUS)
compared to either conventional climatotherapy at the Dead Sea
alone or with placebo cream in combination with climatotherapy.
This combined therapy is significantly faster in repigmentation
than narrowband UVB activated pseudocatalase cream (PC-KUS) treatment
alone. The results of this study support the necessity of epidermal
H2O2 removal as well as the influence of solar UV-light in the
successful treatment of vitiligo.

Vitiligo: a manifestation of apoptosis?
Huang CL, Nordlund JJ, Boissy R.
Department of Dermatology, University of Cincinnati, Pavilion
A, Ohio 45267-0523, USA.
Vitiligo is a common cutaneous disorder that has significant
biological and social consequences for those affected. It is characterized
by a loss of melanocytes from the epidermis, which results in
the absence of melanin, i.e. depigmentation. There are numerous
hypotheses about the etiology of vitiligo, but no data to definitively
prove one theory over another. It is likely that there are numerous
causes for the loss of these melanocytes. One way to approach
the identification of the etiology is to determine the mechanism
by which the melanocytes are destroyed. The two known mechanisms
for the destruction of cells are necrosis and apoptosis. One purpose
of this paper is to review the extant data that might suggest
which of the two mechanisms is operative against melanocytes in
patients with vitiligo. The histological data, and some laboratory
data, support apoptosis, rather than necrosis, as the mechanism
for removal of melanocytes. Apoptosis can be induced by a variety
of factors, including immune cytokines, some environmental chemicals
(for example substituted hydroquinones such as monobenzone) or
other molecular mechanisms. Current therapies, such as corticosteroids
and ultraviolet light, do affect apoptosis in a variety of ways.
Confirmation of apoptosis as a mechanism, and identification of
how apoptosis is initiated to produce vitiligo, can serve as a
basis for devising medications that might stop the progression
of the disorder. The problem of vitiligo would be essentially
solved if there was a medication that is well tolerated in children,
adults and pregnant women, and that would halt the progression
of the depigmentation. The study of apoptosis, mechanisms of its
induction, and the ways to block apoptosis, is one possible way
to find both the causes of depigmentation and medications to prevent
its progression.

Treatment of vitiligo with the 308-nm excimer
laser: a pilot study.
Spencer JM, Nossa R, Ajmeri J.
Division of Dermatologic Surgery, Mount Sinai School of Medicine,
New York, NY 10029, USA.
BACKGROUND: Present vitiligo therapies require many months
of treatment and often result in disappointing outcomes. Common
therapeutic options include phototherapy with psoralens plus ultraviolet
A (UVA) radiation and broadband or narrowband UVB radiation phototherapy.
Some of these modalities require regular phototherapy sessions
several times a week for up to a year to achieve a therapeutic
response. Targeted phototherapy with single-wavelength laser light
is a treatment alternative that may prove to be a time-efficient
and effective therapeutic option for the management of vitiligo.
METHODS: This intervention study was designed as a before and
after trial with a single arm. Twenty-nine patches of vitiligo
from 18 patients (6 males and 12 females) were treated at the
start of the study. Vitiligo patches were treated by using a 308-nm
xenon-chloride excimer laser. Lesions were treated 3 times a week
for a maximum of 12 treatments. Treatment was withheld if sunburn
was observed and held until resolution. All patients had untreated
vitiligo patches that served as control sites. RESULTS: Twenty-three
vitiligo patches from 12 patients received at least 6 treatments
and resulted in some repigmentation in 57% of the treated patches.
Eleven vitiligo patches from 6 patients received all 12 treatments
and resulted in some repigmentation in 82% of the treated patches.
Untreated control patches remained unchanged. CONCLUSION: This
degree of repigmentation in a period of 2 to 4 weeks is much higher
than that achieved with any other present vitiligo therapy. The
xenon-chloride excimer laser may represent a new treatment modality
for the management of stable vitiligo.

Psoralen photochemotherapy (PUVA) is only moderately
effective in widespread vitiligo: a 10-year retrospective study.
Kwok YK, Anstey AV, Hawk JL.
Photobiology Unit, Department of Environmental Dermatology, St
John's Institute of Dermatology, St Thomas' Hospital, London SE1
7EH, UK.
A 10-year retrospective analysis of the use of psoralen photochemotherapy
(PUVA) in the treatment of vitiligo was undertaken at the St John's
Institute of Dermatology, London, UK. Of 97 patients included
in this study, eight had complete or almost complete repigmentation,
59 moderate to extensive repigmentation, and 30 showed little
or no response. However, 24 of those who had responded to PUVA
with extensive repigmentation did not consider their response
satisfactory because of persistence of vitiligo at cosmetically
sensitive sites, and poorly matching, speckled repigmentation.
Fifty-seven patients who initially improved with PUVA therapy
subsequently relapsed, in most cases within a year of stopping
treatment. Relapses in 22 patients were on the same cutaneous
sites as previously affected, while vitiligo at new sites developed
in 20 patients and both new and old sites were affected in a further
15 patients. Patients who retained their pigmentation after 2
years appeared to have a better chance of permanent remission.
The only statistically significant prognostic indicator of relapse
was patient age at the start of treatment, younger patients tending
to retain their pigmentation longer than older patients. This
study emphasizes the need for careful patient counselling before
PUVA therapy as this treatment seldom achieves extensive repigmentation
that is cosmetically acceptable, and treatment response is often
followed by relapse.

and the clinical improvement in vitiligo patients treated with
PUVA.

Solar-simulated UV-irradiation causes changes in the enzymic
antioxidant defence system in the human epidermis. The aim of
this study was to investigate the effects on the skin lipid peroxidation
and clinical improvement in vitiligo patients treated with PUVA.
The first group of patients was treated for six months with psoralen
plus UV-A (n = 15). The second group of patients was treated for
six months with psoralen plus UV-A vs vitamin E (900 IU daily
perorally) (n = 15). There was no significant difference in the
clinical improvement between the group of patients who were treated
with PUVA and vitamin E and the group of patients treated with
PUVA alone (p > 0.05). Statistical analysis revealed a significant
difference between the levels of lipoperoxides before and after
treatment in the first group (p < 0.05), but there was no significant
difference between the levels of lipoperoxides before and after
treatment in the second group (p > 0.05). According to our
results, vitamin E may prevent oxidative distress resulting from
PUVA therapy, but does not affect the clinical improvement of
the vitiligo lesions.

Depigmentation therapy with Q-switched ruby laser
after tanning in vitiligo universalis.
Kim YJ, Chung BS, Choi KC.
Department of Dermatology, Chosun University Hospital, Gwangju,
Korea. yjkim@mail.chosun.ac.kr
BACKGROUND: In vitiligo universalis, repigmentation therapy
is seldom effective. Besides, bleaching cream which is often used
in depigmentation therapy may lead to several serious complications.
OBJECTIVE: Q-switched (QS) ruby laser can destroy melanosomes
in melanocytes and keratinocytes by selective photothermolysis.
METHODS: We have attempted to destroy melanocytes by using the
QS ruby laser after tanning in a patient with extensive vitiligo.
RESULTS: The patient had excellent results with no evidence of
repigmentation after 1 year. CONCLUSION: Depigmentation therapy
with QS ruby laser after tanning is an effective and safe way
of removing remnants of normal pigmentation in patients with vitiligo
universalis.

Modified technique of autologous noncultured epidermal
cell transplantation for repigmenting vitiligo: a pilot study.
Van Geel N, Ongenae K, De Mil M, Naeyaert JM.
Department of Dermatology, Ghent University Hospital, Ghent, Belgium.
BACKGROUND: Several reports have demonstrated that grafting
of autologous melanocytes from normally pigmented donor skin can
be used for repigmentation of achromic macules in vitiligo. OBJECTIVE:
To investigate a modified approach in which noncultured autologous
melanocytes and keratinocytes are grafted on superficially laser
dermabraded vitiligo lesions in a suspension enriched with hyaluronic
acid. METHODS: Four patients with stable vitiligo were treated
using a noncultured melanocyte-keratinocyte suspension. The cellular
suspension was grafted on vitiliginous lesions previously dermabraded
with a CO2 laser. To improve the viscosity and fixation of the
cellular suspension hyaluronic acid was added. Three weeks after
grafting, psoralen plus ultraviolet A (PUVA) or ultraviolet B
(UVB) therapy was started. Residual leukodermic areas were subsequently
retreated. RESULTS: Repigmentation was observed within 2-4 weeks
and continued to increase for 3 months after treatment. In all
patients, 85-100% repigmentation was achieved. A temporary slight
color mismatch was visible in all patients. The most homogeneous
repigmentation was obtained 5 months after treatment. CONCLUSION:
This modified procedure seems to be a simple and promising treatment
for larger vitiliginous areas.

Epidermal grafting after chemical epilation in
the treatment of vitiligo.
Kim CY, Yoon TJ, Kim TH.
Department of Dermatology, College of Medicine, Gyeongsang National
University and Gyeongsang Institute of Neuroscience, Chinju, Republic
of Korea.
BACKGROUND: Vitiligo on hairy areas like the scalp and eyebrows
is frequently associated with leukotrichia and repigmentation
by photochemotherapy is usually difficult because of a deficient
melanocyte reservoir. Although epidermal grafting to supply melanocytes
is very effective for stable vitiligo, hair growth inhibits successful
transfer of melanocytes from grafted epidermis in dense hair-bearing
regions. OBJECTIVE: To investigate the effectiveness of preoperative
chemical epilation to improve the results of epidermal graft by
suction blister on hairy areas. METHODS: Two patients who had
vitiligo with leukotrichia on the face and scalp were treated
with epidermal grafting using suction blister after chemical epilation.
Two weeks after the graft they were treated with topical psolaren
plus ultraviolet A (PUVA) therapy. RESULTS: Epidermal grafting
was performed successfully, and successful repigmentation of the
skin with significant improvement of leukotrichia was observed
in each of two patients. CONCLUSION: Chemical epilation followed
by epidermal grafting is a safe, easy, and effective treatment
for vitiligo affecting hairy regions.

Vitiligo. Pathogenesis and treatment.
Njoo MD, Westerhof W.
Department of Dermatology, Academic Medical Centre, University
of Amsterdam, Amsterdam, The Netherlands.
Vitiligo is an acquired skin disorder caused by the disappearance
of pigment cells from the epidermis that gives rise to well defined
white patches which are often symmetrically distributed. The lack
of melanin pigment makes the lesional skin more sensitive to sunburn.
Vitiligo can be cosmetically disfiguring and it is a stigmatizing
condition, leading to serious psychologic problems in daily life.
It occurs worldwide in about 0.5% of the population and it occurs
as frequently in males as it does in females. The cause is unknown,
but might involve genetic factors, autoimmunity, neurologic factors,
toxic metabolites, and lack of melanocyte growth factors. Since
a causative (gene) treatment is not (yet) available, current modalities
are directed towards stopping progression and to achieving repigmentation
in order to repair the morphology and functional deficiencies
of the depigmented skin areas. Many treatments have been used
for some time; however; there are some new developments: narrowband
ultraviolet (UV) B (311 nm) therapy, the combination of corticosteroid
cream + UVA therapy, and the transplantation of autologous pigment
cells in various modalities. In widespread vitiligo, residual
pigment can be removed by depigmentation agents. Sunscreens, camouflage
products, and good guidance may help the patient cope better with
the disease.

Vitiligo: a retrospective comparative analysis
of treatment modalities in 500 patients.
Handa S, Pandhi R, Kaur I.
Department of Dermatology, Venereology & Leprology, Postgraduate
Institute of Medical Education & Research, Chandigarh, India.
The major non-surgical re-pigmenting therapies for vitiligo
include psoralens and corticosteroids, used both topically and
systemically. In an attempt to determine the best therapeutic
option, we compared the efficacy of various treatment regimens
used in our department for the treatment of vitiligo. We report
herein our results with six different regimens used in our clinic.
Data from five hundred vitiligo patients who attended the pigmentary
disorders clinic at the Nehru Hospital, PGI, Chandigarh, was analysed.
For the purpose of analysis, patients were arbitrarily divided
into two groups based upon the body surface area (BSA) involved:
Group A (<10% BSA involved) and B (>10% BSA involved). Group
A was further divided into three subgoups of patients depending
upon what treatment they received: R-I [topical clobetasol propionate+sun
exposure]; R-II [topical psoralen+sun exposure (topical PUVASOL)];
R-III [topical psoralen+UVA (topical PUVA)]. Group B was also
subdivided into three subgroups of patients who received: R-IV
[oral dexamethasone pulse therapy + sun exposure]; R-V [systemic
psoralen + sun exposure (systemic PUVASOL)]; R-VI [systemic psoralen
+ UVA (systemic PULVA)]. Patients who had undergone, one of the
above mentioned regimens and had a regular monthly follow up until
total re-pigmentation or for at least one year, whichever was
earlier, were included in the final assessment of the therapeutic
efficacy of that regimen. At the end of the study in Group A,
207 (89%) patients out of 232 on R-I; 73 (93%) out of 78 on R-II,
and 15 (79%) out of 19 patients on R-III showed moderate to excellent
re-pigmentation, respectively. In group B, 45 (81%) patients out
of 55 on R-IV, 48 (84%) out of 57 on RV, and 22 (84%) patients
out of 26 on R-VI showed moderate to excellent re-pigmentation.
Statistically, in Group A, R-I & II were significantly better
than R-III. However in Group B, there was no significant difference
in the responses to R-IV, V, and VI. A positive family history
of vitiligo did not seem to affect the response rate. Potent topical
steroids used along with sun exposure and topical PUVASOL were
the most effective forms of therapy for localised vitiligo. For
the generalised form of the disease, we concluded that all the
systemic modalities, oral steroids, PUVASOL and PUVA, are equally
efficacious over a period of one year. Phototoxic reactions were,
however, more common with PUVASOL.

Topical calcipotriol as monotherapy and in combination
with psoralen plus ultraviolet A in the treatment of vitiligo.
Ameen M, Exarchou V, Chu AC.
Unit of Dermatology, Imperial College of Science, Technology and
Medicine, Hammersmith Hospital, Du Cane Road, London W12 0HS,
UK.
BACKGROUND: Recent advances in the pathophysiology of vitiligo
have demonstrated defective calcium homeostasis in depigmented
skin. 1,25-Dihydroxyvitamin D3 may be involved in the regulation
of melanin synthesis, and receptors for 1,25-dihydroxyvitamin
D3 have been demonstrated on melanocytes. OBJECTIVES: We conducted
an open study to determine the efficacy and tolerability of calcipotriol
cream as monotherapy and in conjunction with psoralen plus ultraviolet
A (PUVA) in the treatment of vitiligo. METHODS: Twenty-six patients
with vitiligo affecting 5-40% of their skin were recruited. Twenty-two
were treated with twice-daily topical calcipotriol monotherapy
(50 microg g(-1)) and four were placed on combination treatment
with twice-daily topical calcipotriol 50 microg g(-1) in conjunction
with topical or oral 8-methoxypsoralen PUVA three times weekly.
RESULTS: Treatment was well tolerated at all sites and no adverse
effects were reported. After a therapy time of 3-9 months (mean
6 months), 77% (17 of 22) of those treated with monotherapy showed
30-100% improvement, and three of the four patients on combination
treatment showed good response. CONCLUSIONS: Topical calcipotriol
appears to be an effective and well-tolerated treatment for vitiligo
and can be safely used in conjunction with PUVA, but controlled
studies are necessary to exclude the possibility of spontaneous
repigmentation.

Is the efficacy of psoralen plus ultraviolet A
therapy for vitiligo enhanced by concurrent topical calcipotriol?
A placebo-controlled double-blind study.
Ermis O, Alpsoy E, Cetin L, Yilmaz E.
Department of Dermatology, Akdeniz University School of Medicine,
07070 Antalya, Turkey.
BACKGROUND: Encouraging results of previous uncontrolled trials
suggest that calcipotriol may potentiate the efficacy of psoralen
plus ultraviolet (UV) A (PUVA) therapy in patients with vitiligo.
OBJECTIVES: We performed a placebo-controlled double-blind study
to investigate whether the effectiveness of PUVA treatment could
be enhanced by combination with topical calcipotriol in the treatment
of vitiligo. METHODS: Thirty-five patients with generalized vitiligo
enrolled in the study. Symmetrical lesions of similar dimensions
and with no spontaneous repigmentation on arms, legs or trunk
were selected as reference lesions. In this randomized left-right
comparison study, calcipotriol 0.05 mg g(-1) cream or placebo
was applied to the reference lesions 1 h before PUVA treatment
(oral 8-methoxypsoralen and conventional UVA units) twice weekly.
Patients were examined at weekly intervals. The mean number of
sessions and the cumulative UVA dosage for initial and complete
repigmentation were calculated. RESULTS: Twenty-seven patients
(nine women, 18 men; mean +/- SEM age 29.8 +/- 13.5 years) were
evaluated. The mean +/- SEM cumulative UVA dose and number of
UVA exposures for initial repigmentation were 52.52 +/- 6.10 J
cm(-2) and 9.33 +/- 0.65 on the calcipotriol side, and 78.20 +/-
7.88 J cm(-2) and 12.00 +/- 0.81 on the placebo side, respectively
(P < 0.001). For complete repigmentation, respective values
were 232.79 +/- 14.97 J cm(-2) and 27.40 +/- 1.47 on the calcipotriol
side and 259.93 +/- 13.71 J cm(-2) and 30.07 +/- 1.34 on the placebo
side (P = 0.001). Treatment with calcipotriol and PUVA resulted
in significantly higher percentages of repigmentation for both
initial (81%) and complete pigmentation (63%), compared with placebo
and PUVA (7% and 15%, respectively). CONCLUSIONS: Our results
have shown that concurrent topical calcipotriol potentiates the
efficacy of PUVA in the treatment of vitiligo, and that this combination
achieves earlier pigmentation with a lower total UVA dosage.
