In order to evaluate the efficacy of L-phenylalanine (L-Phe) in combination with UVA therapy for vitiligo an open trial (149 patients, 18 months) and a small double-blind trial (32 patients, 6 months) were conducted. Oral L-Phe loading resulted in peak plasma levels of L-Phe after 30-60 min and a slight increase in the plasma tyrosine level. Response to L-Phe plus UVA irradiation was positive, and various grades of repigmentation not exceeding 77% in the open and 60% in the blind trial were observed. An increased L-Phe dose resulted in increased L-Phe plasma levels but not in improved clinical results. The optimal L-Phe dose appears to be lower than 50 mg/kg/day. Although it is difficult to draw firm conclusions from the present investigation, we think that L-Phe may have a place in the treatment of vitiligo and its role merits further investigation. nan Vitiligo is a chronic illness of a yet unknown etiology, characterized by an acquired and progressive depigmentation of the skin. There are diverse treatments for this condition around the world, but up to now, none has been completely effective. The objective of this work was to evaluate the application of an antioxidant and mitochondrial stimulating formula, of topic use in leukodermic areas of patients with stable vulgar vitiligo. A clinical, experimental, randomized, double blind study was carried out in 50 male and 50 female patients with stable vulgar vitiligo. The patients were distributed in five groups as follows: Group 1 (labelled as VitilVenz AF): application of antioxidant and mitochondrial stimulating cream and oral administration of antioxidants and phenylalanine. Group 2 (labelled as Placebo AF): application of a placebo cream and oral administration of antioxidants and phenylalanine. Group 3 (labelled as without cream AF): oral administration of antioxidants and phenylalanine. Group 4 (labelled as Placebo cream): application of a placebo cream. Group 5 (labelled as VitilVenz): application of the antioxidant and mitochondrial stimulating cream. The following were measured in all patients: the clinical area of newly formed pigment every 30 days, during five months; and the presence of melanocytes in the histological study, at the beginning and at the end of treatment. The test of multiple comparison of Turkey-Kramer was used for the analysis of the results. The scheme of treatment that produced the best results was that of the Group 1, which consisted of the joint application of the antioxidant and mitochondrial stimulating cream and oral administration of antioxidants and phenylalanine (p < 0.001); followed by Group 5 that only received the topical treatment with the antioxidant and mitochondrial stimulating cream. The clinical and histological responses of these two groups (1 and 5) were significantly different to the rest of the groups. We concluded that the melanocytes in these patients could be in a dysfunctional state, product of the formation of free radicals that cause cellular and mitochondrial toxicity; and that these free radicals are removed by the antioxidant and mitochondrial stimulating elements present in the cream, turning the melanocytes functional and producing melanin in the achromic area of the vitiligo. This effect would be potentiated by the use of oral antioxidants and phenylalanine. Both types of Ultraviolet (UV), UVB (290-320 nm) and UVA (320-400 nm), produce increased pigmentation or tanning. However, no evaluation of UVA alone in the treatment of vitiligo has been reported. Therefore, it was the purpose of this work to study the pigmentogenic effect of UVA (5 and 15 J/cm(2)) in vitiligo. The study included 20 randomly selected patients with vitiligo involving more than 30% of the body surface area with a bilateral/symmetrical distribution. They were equally divided into two groups each of 10 patients. All patients received three weekly sessions of UVA, 15 J/cm(2) in group I and 5 J/cm(2) in group II, a total of 48 sessions over 16 weeks. Overall pigmentation of 60% and above was recorded in 50% and 10% of patients in groups I and II, respectively. We conclude that broadband UVA alone, without psoralens, and in appropriate doses may be of important therapeutic value in vitiligo. 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. 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.
                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.
                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).
                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. 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.
                To assess the efficacy of levamisole in the treatment of slowly spreading, limited vitiligo.
                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.
                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.
                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. Vitiligo is a common skin disease which is difficult to treat. Approximately half of patients acquire the disease before the age of 20 years. This disease has a high stigmatizing impact but no ideal, aetiology-oriented, effective therapy has been found to date. Tacalcitol and other vitamin D analogues have been shown to have stimulating activity both on immunomodulatory mediators and on melanocytes in lesional skin.
                To investigate the efficacy and safety of tacalcitol ointment plus sunlight exposure in the treatment of nonsegmental vitiligo.
                A single-centre, randomized, double-blind, vehicle-controlled study including 80 patients with nonsegmental vitiligo was carried out in a specialized outpatient dermatology clinic within a tertiary care, university-affiliated hospital in Spain. Efficacy was assessed by quantification of the lesional repigmentation area at the end of the study compared with the baseline. Tacalcitol (n = 40) or matching placebo ointment (n = 40) was applied once a day at night. Daily exposure to sunlight for 30 min was performed. Treatment was continued for 4 months. The response of the lesions was clinically verified every 2 weeks by a blinded medical investigator. All adverse effects were recorded.
                Eighty adult patients with nonsegmental vitiligo were recruited. Over 16 weeks, 64 patients completed the study requirements. There was no significant difference in the repigmentation response at the 16-week time point between the vehicle + sunlight exposure and the tacalcitol + sunlight exposure groups. No reduction in the size of the lesions > 25% was observed in the tacalcitol-treated patients. No serious adverse effects were observed.
                The combination of tacalcitol with heliotherapy has no additional advantages compared with heliotherapy alone. 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.
                A prospective, randomized, double-blind, placebo-controlled study.
                Ambulatory patients in an institutional practice. Patients were followed up for 3 to 12 months.
                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).
                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.
                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.
                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.
                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. 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. Vitiligo is a common pigmentary disorder with great cosmetic and psychological morbidity. No treatment available is a definitive cure. Systemic psoralen and ultraviolet A (PUVA) has been the mainstay of treatment. Narrow-band ultraviolet B (NB-UVB) has been recently introduced. Although retrospective comparative study of systemic PUVA and NB-UVB has been published from our centre, no prospective study has been reported to date.
                To investigate the position of NB-UVB vis-à-vis PUVA in terms of efficacy, time to repigment and adverse effects and to help decide if one therapy has an advantage over another in the treatment of vitiligo.
                It was a randomized, open, prospective study of 50 patients divided equally in TMP PUVA and NB-UVB groups. The study period was from January 2004 to June 2005.
                The mean degree of repigmentation attained in the NB-UVB group was 52.24% over a mean treatment period of 6.3 months, whereas in the PUVA group it was 44.7% in a mean period of 5.6 months (P=0.144). After excluding the results of therapy-resistant sites, that is, hands and feet, the mean degree of repigmentation in the NB-UVB group was 67.57%, whereas in the PUVA group it was 54.2% (P=0.007).
                NB-UVB performed better in comparison to TMP PUVA in terms of mean total repigmentation when traditionally considered therapy-resistant sites were excluded. Punch grafting followed by PUVA is an established therapy for stable vitiligo, but punch grafting followed by topical corticosteroid has never been evaluated.
                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.
                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.
                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.
                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. Surgical therapy of vitiligo is indicated when depigmented macules are localized in areas that are known to respond poorly.
                The objective was to compare the results of treatment of vitiliginous macules localized in the dorsum of the hands and lower limbs by transplantation of cultured autologous melanocytes plus PUVA therapy (CMP), suction blister transplantation plus PUVA therapy (SBP), cryotherapy plus PUVA therapy (CP), and only PUVA therapy (OP).
                Twenty patients qualified for the study. The patients were split into two groups of 10 patients. In the first group, the CMP procedure was performed on one limb and OP on the other. In the second group, SBP and CP were used, respectively.
                The CMP procedure was successfully performed on only 6 of 10 patients, whereas SBP was carried out on all 10 patients. No significant difference was found between the number of successful transplants in both groups of patients. A total lack of effectiveness was found in CP and OP methods.
                This study demonstrated the advantage of the suction blister transplantation method over the autologous cultured melanocytes transplantation method because of the difficulties in cell culture establishment in some cases. In this paper, we report on 366 East Indian patients with vitiligo who were treated for 2 to 3 years with either 8-methoxypsoralen (8-MOP), 4,5',8-trimethylpsoralen (TMP), or psoralen and sunlight. These patients with amelanotic macules had 10 to 70% skin involvement of 1 to 50 years duration. Male and female patients from ages 12 to 70 years were randomly assigned to 8 treatment groups; the study was conducted on a double-blind protocol. Patients in prone and supine positions were exposed to the sun for 45-60 minutes in gradually increasing doses between 11 a.m. and 2 p.m. thrice weekly and 2 hours after oral ingestion of the drug. The various drug dosage schedules investigated included 9 groups: 0.3 and 0.6 mg 8-MOP/kg; 0.8, 1.8, and 3.6 mg TMP/kg; a combination of 0.3 mg 8-MOP and 0.6 mg TMP/kg; 0.6 and 1.2 mg psoralen/kg, and a placebo. For ethical reasons, the placebo group was terminated after 9 to 12 months of therapy. All patients were photographed before enrollment and at intervals of 6, 12, 18, and 26 months during therapy. Of these patients treated for nearly 2 years, the faces of those 45% receiving the combination dose of 8-MOP plus TMP or low-dose 8-MOP (0.3 mg/kg) were fully repigmented, and nearly 60% achieved 75 to 100% repigmentation of the head and neck. The chest, abdomen, and back were repigmented nearly as well and better than the arms and legs. The patients receiving high-dose schedules of TMP and psoralen achieved better repigmentation response than those on lower dosage but still not as good as patients on 8-MOP or the combination group of 8-MOP plus TMP.(ABSTRACT TRUNCATED AT 250 WORDS) The first choice treatment for vitiligo vulgaris is narrow-band UVB (NB-UVB), but no satisfactory treatment exists.
                To investigate if Polypodium leucotomos, an antioxidative and immunomodulatory plant extract, improves NB-UVB-induced repigmentation.
                Fifty patients with vitiligo vulgaris randomly received 250 mg oral P. leucotomos or placebo three times daily, combined with NB-UVB twice weekly for 25-26 weeks.
                Repigmentation was higher in the P. leucotomos group vs. placebo in the head and neck area (44% vs. 27%, P = 0.06). Small repigmentation increases (P = n.s.) were observed for the trunk (6% increased repigmentation), extremities (4%), and hands and feet (5%) in the P. leucotomos group vs. placebo. Patients attending more than 80% of required NB-UVB sessions showed increased repigmentation in the head and neck area in the P. leucotomos group vs. placebo (50% vs. 19%, P < 0.002); no significant differences were seen in the other body areas. Patients with skin types 2 and 3 showed more repigmentation in the head and neck area in the P. leucotomos group vs. placebo (47% vs. 21%, P = 0.01), and no significant differences were seen in the other body areas. No conclusions could be drawn on skin types 4 and 5 due to low patient numbers.
                There is a clear trend towards an increase in repigmentation of vitiligo vulgaris affecting the head and neck area when NB-UVB phototherapy is combined with oral P. leucotomos. This effect may be more pronounced in light skin types. To study and compare the efficacy of combined 308-nm monochromatic excimer light (MEL) therapy with tacalcitol vs. that of MEL 308-nm therapy alone in treatment of vitiligo.
                Thirty-eight patients with vitiligo were enrolled in a single-blind, within patient controlled clinical trial. Symmetrical or nearby lesions were randomly applied with either topical tacalcitol cream or vehicle. Each lesion was treated weekly with the 308-nm MEL, for a total of 12 sessions. Patients were examined at monthly intervals. The mean number of sessions and the cumulative dosage for initial repigmentation were calculated.
                Thirty-five patients were evaluated. Treatment with tacalcitol and MEL resulted in higher percentages for excellent repigmentation (25.7%) compared with vehicle and MEL (5.7%) (P<0.05). Percentages for total response were 71.4% and 60%, respectively (P>0.05). The mean+/-SEM cumulative dose and number of excimer light exposures for initial repigmentation were, respectively, 3.93+/-0.59 J/cm2 and 4.52+/-0.49 at the tacalcitol side, and, respectively, 4.99+/-0.68 J/cm2 and 5.3+/-0.52 at the vehicle side (P<0.05).
                Our results have shown that concurrent topical tacalcitol potentiates the efficacy of the 308-nm MEL in the treatment of vitiligo, and that this combination achieves earlier pigmentation with a lower total dosage. Vitiligo is an acquired depigmenting disease with uncertain aetiopathogenesis, possibly associated with oxidative stress. Narrowband ultraviolet B phototherapy (NB-UVB) is the most widely used and effective treatment.
                To evaluate the clinical effectiveness of NB-UVB and the repairing of oxidative stress-induced damage, using oral supplementation with an antioxidant pool (AP).
                Patients (n = 35) with nonsegmental vitiligo were enrolled in a randomized, double-blind, placebo-controlled multicentre trial. The treatment group received, for 2 months before and for 6 months during the NB-UVB treatment, a balanced AP containing alpha-lipoic acid, vitamins C and E, and polyunsaturated fatty acids. The area and number of lesions, as well as some parameters of the oxidation-reduction (redox) status of the peripheral blood mononuclear cells (PBMCs) were estimated at the beginning, after 2 months, and at the end of the trial.
                In total, 28 patients completed the study. After 2 months of AP supplementation, the catalase activity and the production of reactive oxygen species (ROS) were 121% and 57% of the basal values (P < 0.05 and P < 0.02 vs. placebo, respectively). The AP increased the therapeutic success of NB-UVB, with 47% of the patients obtaining > 75% repigmentation vs. 18% in the placebo group (P < 0.05). An increase in catalase activity to 114% (P < 0.05 vs. placebo) and decrease in ROS level of up to 60% (P < 0.02 vs. placebo) of the basal value was observed in PBMCs. Finally, the AP intake maintained the membrane lipid ratio (saturated : unsaturated fatty acids 1.8 : 3.1; P < 0.05), counteracting phototherapy-induced saturation.
                Oral supplementation with AP containing alpha-lipoic acid before and during NB-UVB significantly improves the clinical effectiveness of NB-UVB, reducing vitiligo-associated oxidative stress. To assess the safety and efficacy of topical 0.1% tacrolimus vs 0.05% clobetasol propionate.
                Randomized double-blind trial.

                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.
                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.
                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.
                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. A large variety of therapeutic agents are being used for the treatment of vitiligo, but treatment remains a challenge. Recently, monochromatic phototherapies such as 311-nm narrowband ultraviolet B therapy and 308-nm xenon chloride excimer laser have been reported to be an effective and safe therapeutic option in children and adult patients with vitiligo. Single reports stipulate that the addition of topically applied calcipotriol to phototherapy increases its effectiveness.
                The purpose of the present pilot study was to determine if the addition of topical calcipotriol increases the efficacy of the 308-nm xenon chloride excimer in the treatment of vitiligo.
                Ten patients with vitiligo with essentially bilateral symmetrical lesions were enrolled in this prospective right/left comparative, single-blinded trial conducted over a 15-month period. All patients received 308-nm XeCl excimer laser therapy three times weekly. Calcipotriol ointment (Daivonex) was applied to lesions on one side of the body twice daily.
                After 24 treatments (8 weeks), nine patients were evaluated. Eight patients showed evidence of repigmentation on both body sides, with no significant difference between the body side treated with calcipotriol and excimer laser and the side treated with excimer laser alone. The mean repigmentation rate was 22.4% (1-37%).
                The addition of calcipotriol ointment to 308-nm xenon chloride excimer laser phototherapy does not significantly enhance its efficacy. Small additive effects must be investigated in a larger trial. 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.
                To compare the two techniques in patients with chronic stable localized vitiligo.
                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.
                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.
                SSG carries a distinct advantage over MPG in producing excellent cosmetic matching over larger areas using fewer grafts, especially over the face and extremities. To observe the clinical efficacy of Zengse Pill ( ZSP) on patients with vitiligo of qi-stagnancy and blood-stasis syndrome type (V-QB), and to preliminarily explore its mechanism of action.
                Sixty-five V-QB patients, with their diagnosis confirmed by clinical examination, were randomized by digital table method into two groups, with 31 patients in the control group and 34 in the treatment group. Cobamamide (2 tablets) was administered orally to all patients, and Psoralea tincture (a self-formulated preparation) was applied externally thrice a day. In addition, for patients in the treatment group, ZSP was given orally, at 5 pills per dose, 3 times every day. The therapeutic course for both groups was 3 months. Patients were re-examined every half-month, and changes in the skin lesions were observed and recorded. The levels of lymphocyte subsets, serum immune globulin, and complement C3 and C4 in patients were determined before and after the therapeutic course and compared with the corresponding indexes determined in 21 healthy subjects.
                The total effective rate in the treatment group was 82.4%, which was markedly higher than that in the control group (54.8%), showing a significant difference (P<0.05). After treatment, CD(4) (+) percentage, CD(4) (+)/CD(8) (+) ratio, and blood levels of C3 and C4 increased, while CD(8) (+) percentage decreased in the treatment group (P<0.05 or P<0.01). All these indexes remained unchanged in the control group, and the respective comparisons between groups showed significant differences (P<0.01).
                ZSP has a definite clinical effect on the treatment of V-QB but with no evident adverse reactions, and it can increase the CD(4) (+) percentage, CD(4) (+)/CD(8) (+) ratio, and the levels of serum C3 and C4, thus regulating the immunity of the organism, which might be one of its mechanisms of action. nan 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. nan nan A large variety of therapeutic agents are being tried for the treatment of vitiligo, but psoralens continue to be mainstay of treatment although they are not uniformly effective. Recent advances in pathophysiology have established a perturbed calcium homeostasis in affected skin, and melanocytes were shown to express vitamin D3 receptors.
                The purpose of present study was to determine the efficacy of the combination of PUVAsol with topical calcipotriol in the treatment of vitiligo.
                Nineteen patients with essentially bilateral symmetrical lesions were enrolled in a randomized, double-blind, right/left comparative study of 18 months duration. An oral dose of 0.6 mg/kg 8-methoxypsoralen was given 2 h before exposure to sunlight thrice weekly to all patients. The patients were advised to apply calcipotriol (50 microgram/g) on one side of the body and placebo ointment over the lesions on the other side twice daily.
                At the end of 6 months, 12 patients (70%) showed marked to complete improvement on calcipotriol-treated sides as compared to 6 patients (35%) showing similar improvement on placebo-treated sides (p <0.05). At the end of treatment, 13 patients (76%) showed marked improvement in calcipotriol-treated lesions whereas 9 patients (53%) showed moderate to marked improvement in placebo-treated lesions. The repigmentation of hands and feet was much better with the combination of PUVAsol and calcipotriol.
                The combination of PUVA and calcipotriol is highly effective and works faster and may be used for shortening the therapy with PUVA in the treatment of vitiligo. NB-UVB phototherapy is a very important modality in treating vitiligo but the treatment course usually exceeds 1 year. Skin ablation with mechanical dermabrasion with 5Fluorouracil (5FU) was introduced to treat vitiligo in 1983. This was modified replacing the mechanical dermabrasion by erbium-YAG (ER:YAG) laser ablation and resulted in better prognosis in periungual vitiligo. Purpose: In the present study, we are exploring the effect of the use of ER:YAG laser skin ablation and application of 5FU on the outcome of short-term NB-UVB therapy for patients with non-segmental vitiligo (NSV).
                This study included 50 adult patients with a total of 65-paired symmetrical NSV lesions in different body parts. One side was treated with ER:YAG laser ablation, followed by 5FU application before simultaneous NB-UVB therapy of both sides for a maximum period of 4 months. The outcome was then evaluated both qualitatively and quantitatively.
                The overall response to therapy was better using the combination therapy. Fifty patients (78.1%) experienced a moderate-marked repigmentation response in the combination group compared with 23.4% in the mono-therapy group. The response was significantly higher when using the combination therapy in different body parts (P value is <0.05), except for feet lesions, which were better but not statistically significant (P value=0.15). Tolerable pain during ablation or at sites of 5FU application was reported in all cases. Transient hyperpigmentation occurred in 30% of cases and 3.1% of lesions healed by a transient slate blue color. Half of the treated periungual lesions showed a temporary tiny brownish spot on nail plates and Köebnerization was not detected in any patient.
                We concluded that prior use of ER:YAG laser skin ablation, followed by 5FU application before NB-UVB phototherapy for vitiligo is a safe and tolerable technique that improves the outcome of short-term NB-UVB therapy and is expected to increase patient compliance. To compare the efficacy and safety of using a combination of fluticasone propionate (FP) and UV-A with that of either drug used alone in the long-term treatment of vitiligo.
                Prospective, randomized, controlled, left-right comparison study. Repigmentation was judged by a single dermatologist (L.N.-K.) and skin thickness was scored by a pathologist (using biopsy samples), a dermatologist (L.N.-K.) (visually), and patients (using a standard questionnaire).
                Netherlands Institute for Pigmentary Disorders, Amsterdam.
                Patients with lesions on arms, legs, and trunk were treated on 2 symmetrical lesions for 9 months with FP alone and a combination of FP and UV-A (FP group) or with UV-A alone and a combination of FP and UV-A (UV-A group). Fluticasone propionate cream was applied once daily at about bedtime, and UV-A (10 J/cm2) exposure was twice a week. Patients attended the clinic at 3-month intervals.
                One hundred thirty-five patients were included, 96 of whom were evaluable after 9 months. Patients not reaching the end point withdrew because of insufficient repigmentation (n = 23), decreased motivation (n = 11), or protocol violations (n = 5). No patient (irrespective of whether they withdrew) experienced any adverse effects. The FP and UV-A groups were comparable with respect to sex, age, and location of lesions. On average, combination treatment was 3 times more effective than either UV-A or FP treatment alone. In the FP group, no atrophy was seen after 9 months with either treatment. In the UV-A group, a little atrophy was detected twice: as well during UV-A treatment alone as during combination treatment.
                Combination treatment with FP and UV-A is much more effective in reaching complete repigmentation than are FP and UV-A used alone, but large inter-individual differences occur. Fluticasone propionate, UV-A, and a combination of FP and UV-A seem to be safe for long-term treatment of vitiligo. Previous reports have shown the effectiveness of a basal layer cell suspension in the treatment of stable vitiligo; however, there has been no mention in the literature until now of the optimal number of melanocytes required in an autologous noncultured epidermal suspension for transplantation to obtain early and acceptable results.
                In this randomized prospective study, we compared the efficacy of two different dilutions to determine the optimum density of melanocytes required for transplantation to achieve early and cosmetically acceptable results. We enrolled 20 patients with stable vitiligo with a body surface area involvement of< 10%.
                Fifty per cent of patients in Group A (where the recipient area transplanted was approximately three times the size of the donor area, and the density of melanocytes transplanted per square millimeter was approximately 231.60+/- 27.03) showed marked (> 75%), 20% moderate, 10% mild, and 20% minimal repigmentation (or no response). In Group B (where the recipient area was increased to five-fold the donor area), none of the patients showed marked, 10% showed moderate, 20% showed mild, and 70% showed either minimal or no repigmentation. The density of melanocytes transplanted in this group was 154.90+/- 27.65/mm(2). The extent of repigmentation was significantly greater (P< 0.05) in Group A than in Group B, and the density of melanocytes in the suspension was also significantly greater (P< 0.01) in Group A than in Group B.
                We contend that the minimum number of melanocytes required to produce satisfactory repigmentation is probably in the range of 210-250/mm(2). Vitiligo is an acquired, pigmentary skin disorder which is disfiguring and difficult to treat. In an earlier open label study in adult patients with vitiligo, pimecrolimus cream 1% was reported to have similar efficacy as clobetasol propionate 0.05%. We performed a double-blind, intrapatient comparison of pimecrolimus cream 1% with placebo cream.
                Twenty adult Caucasians with symmetrical vitiligo (predominantly on extremities, none in the face) were treated b.i.d. for 6 months left/right with pimecrolimus/vehicle (N = 10) or vehicle/pimecrolimus (N = 10), respectively. Primary efficacy endpoint was the size of the target lesion at month 6 and secondary efficacy endpoint was re-pigmentation.
                Treatment with pimecrolimus cream 1% or vehicle resulted in no significant change in mean target lesion size. Modest repigmentation (1-25%) was noted with pimecrolimus at month 2 in 12 of 17 patients (vehicle: 9 of 17 patients). Afterwards, the number of patients who experienced an improvement of pigmentation steadily decreased (3 of 14 patients with pimecrolimus and 2 of 14 with placebo at month 6). Treatment was well tolerated. There were no treatment-related adverse events, no induction of skin atrophy nor any other application site side effects.
                In this group of adult patients with symmetrical vitiligo, treatment of body lesions (except face) with pimecrolimus cream 1% could not be shown to be effective. 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.
                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.
                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.
                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).
                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. 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.
                To determine the optimal frequency of 308-nm excimer laser therapy for vitiligo.
                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.
                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.
                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. Vitiligo is a pigmentary disorder which may have disfiguring consequences. Its treatment remains a challenge.
                We designed a parallel-group randomized controlled trial to compare the effectiveness of 308-nm excimer laser alone or in combination with topical hydrocortisone 17-butyrate cream in patients with vitiligo unresponsive to previous treatment with topical steroids or narrow-band ultraviolet (UV) B phototherapy.
                Consecutive patients aged 18-75 years with nonsegmental vitiligo localized on the face and/or neck lacking response to previous conventional treatment were eligible. In total, 84 patients (44 women and 40 men, mean age 44 years) were randomized to 308-nm excimer laser phototherapy twice weekly alone or in combination with topical hydrocortisone 17-butyrate cream twice daily for three periods of 3 weeks followed by a 1-week steroid-free interval. The primary outcome was a reduction of at least 75% of the overall lesional areas as judged by automatic image analysis on reflected UV photographs, conducted blind to treatment assignment, at 12 weeks compared with baseline. Secondary outcomes were clearance, and improvements on Physician's Global Assessment (PGA) and Skindex-29 scores.
                A total of 76 (90%) patients completed the study. In an intention-to-treat analysis, seven [16.6%; 95% confidence interval (CI) 5.3-27.8%] patients in the excimer monotherapy arm and 18 (42.8%; 95% CI 27.8-57.8%) in the combination arm showed > or = 75% reduction of vitiligo lesions at 12 weeks (chi(2) test 6.89, P = 0.0087). Clearance was observed in two (4.7%; 95% CI 1.6-11.2%) and nine (21.4%; 95% CI 9.0-33.8%) patients, respectively (Fisher's exact test P = 0.04). A significant difference also emerged for PGA scores, while no difference was documented for Skindex-29.
                Recalcitrant vitiligo of the face and neck may benefit from the combination of excimer laser phototherapy with topical hydrocortisone 17-butyrate cream. nan 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.
                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.
                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.
                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.
                Combining topical immunomodulators with known phototherapeutic modalities may represent a key advancement in the treatment of disease. There is currently no quantitative tool for evaluating vitiligo treatment response using parametric methods.
                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.
                Prospective, randomized, controlled, bilateral left-right comparison trial.
                North American tertiary care, university-affiliated phototherapy center.
                Patients older than 18 years with stable vitiligo involving at least 5% of their total body surface in a symmetric distribution.
                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.
                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.
                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.
                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. Recently, narrow-band ultraviolet B (NB-UVB) and topical immunomodulators have been successfully used in the treatment of vitiligo.
                To determine whether the combination of pimecrolimus with NB-UVB accelerates the response time and/or improves the degree of response in patients with vitiligo.
                Sixty-eight patients with vitiligo enrolled in this randomized, double-blind, placebo-controlled study. The patients were randomized into two groups and treated with NB-UVB plus either pimecrolimus or placebo for 3 months. Tri-weekly radiation was started at 280 mJ/cm(2), with 15% increments for each subsequent treatment until erythema was reported or a maximum of 800 mJ/cm was achieved. At baseline and 6 and 12 weeks after commencement of therapy, vitiliginous patches were measured.
                Fifty patients completed the 3-month study. No significant side effects except self-limited erythema and pruritus were observed. After 12 weeks of treatment, repigmentation of the facial lesions was higher in patients treated with combined pimecrolimus and NB-UVB compared with the placebo plus NB-UVB group (64.3 vs 25.1%) (p < 0.05%). There was no statistically significant difference in the repigmentation rate between the two groups on other body areas.
                On the face, NB-UVB works better if combined with pimecrolimus 1% cream rather than used alone. 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.
                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.
                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.
                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).
                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. Immunosuppressive agents are used widely in the treatment of vitiligo. Corticosteroids are used either alone or as adjuvant therapy by many practitioners. Cyclophosphamide and cycloporine-A have also been used with variable success. Azathioprine may have the potential for the treatment of vitiligo alone or in combination with other modalities.
                To compare the efficacy of combined low-dose azathioprine and oral PUVA therapy versus oral PUVA therapy alone for the treatment of vitiligo.
                A total of 60 vitiligo patients were randomized to receive either azathioprine (0.6-0.75 mg/kg) and oral PUVA therapy (group 1) or oral PUVA therapy alone (group 2). Patients were followed for 4 months. A graph transparency with squares of 2.5 x 2.5 mm was used to measure the rate of repigmentation after 4 months of therapy.
                Perifollicular repigmentation started after a mean of five sessions in group 1, and eight sessions in group 2. The mean total repigmentation rate after 4 months was 58.4% for group 1 and 24.8% for group 2. No serious side effects were seen during or after treatment.
                Azathioprine may potentiate the repigmentary effects of PUVA therapy in vitiligo patients. A limitation of the study is the lack of validated measures for vitiligo assessment. Several modalities of treatment have been tried in vitiligo with varied results; however, Indian data on comparative studies of two or more therapies are limited.
                We compared different phototherapy methods with an oral steroid as an adjunct to determine the method with the best tolerability and efficacy.
                Eighty-six patients with progressive vitiligo were randomly assigned to different study groups according to a continuous selection method over a period of one year. Group 1 was given OMP + PUVA, group 2 OMP + UVB (NB), group 3 OMP + UVB (BB) and group 4 was given OMP alone. Each patient was followed up for six months and then released from treatment. Clinical evaluation was made at the end of three and six months.
                In group 1 (OMP + PUVA), marked improvement was seen in 18.51% while moderate improvement was seen in 66.66% of the patients. Marked improvement was seen in 37.03% in group 2 (OMP + NB-UVB) while 44.44% had moderate improvement. In group 3 (OMP + BB UVB), 8.33% showed marked improvement while moderate improvement was seen in 25% of the patients. Marked and moderate improvement was seen in 5 and 10% of group 4 (OMP) patients, respectively.
                Our study compared four treatment modalities in vitiligo patients, out of which oral minipulse of steroids (OMP) only had an adjunct value and was not very effective by itself. Narrow band UVB has a definite edge over broad band UVB and should be preferred when both options are available. NB-UVB and PUVA showed comparable efficacy. Vitiligo is an acquired pigmentary disorder characterized by areas of depigmented skin resulting from loss of epidermal melanocytes. Recently, it has been shown that narrowband ultraviolet B (NB-UVB) phototherapy may be more effective than psoralen and ultraviolet A (PUVA) photochemotherapy in treating vitiligo, and that 308-nm monochromatic excimer light (MEL) may present some advantages as compared to NB-UVB for the treatment of vitiligo. AIM The aim of this study was to compare the effectiveness of NB-UVB phototherapy and 308-nm MEL in vitiligo patients.
                The study was done in a randomized, investigator-blinded and half-side comparison design. Twenty-one subjects with symmetrical vitiligo lesions were enrolled in this study. Vitiligo lesions on one body side were treated twice weekly for 6 months with 308-nm MEL, while NB-UVB phototherapy was used to treat lesions on the opposite side.
                At the end of the study six lesions (37.5%) treated with 308-nm MEL and only one lesion (6%) treated with NB-UVB achieved an excellent repigmentation (score 4) while four lesions (25%) treated with 308-nm MEL and five lesions (31%) treated with NB-UVB showed a good repigmentation (score 3).
                It appears that 308-nm MEL is more effective than NB-UVB in treating vitiligo lesions and it induces repigmentation more rapidly. Narrowband ultraviolet B (NB-UVB) phototherapy, with a 308-nm xenon chloride excimer laser, and targeted UVB phototherapy have produced encouraging therapeutic results for vitiligo. However, very few studies employing broadband UVB exist. Moreover, there has been no direct comparison study between broadband UVB and NB-UVB for the treatment of vitiligo. The aims of this study were to compare the repigmenting efficacy of targeted broadband UVB phototherapy with that of NB-UVB in an equi-erythemogenic manner. Twenty identical vitiliginous lesions from 10 patients were randomly allocated to receive either targeted broadband UVB or targeted NB-UVB phototherapy. UV fluences were started at 50% of the minimal erythema dose detected within the vitiliginous patches, then increased gradually, in the same manner, to ensure equi-erythemogenic comparison. Treatments were carried out twice weekly for 12 weeks. The results show that grade 1, i.e. 1-25% repigmentation, to grade 2, 26-50% repigmentation, occurred in 6 of 10 subjects. Responses in terms of repigmentation, de-pigmentation, or lack thereof, were similar between lesions receiving broadband and NB-UVB phototherapy. Onset of repigmentation occurred as early as 4 weeks of treatment in most subjects. Treatments were well tolerated, with only minimal erythema and hyperpigmentation.
                The study was carried out in a small number of patients with skin types III, IV and V. The irradiation device was a targeted UVB device and thus the results may not be applicable to other light sources, such as the excimer laser or total-body irradiation cabinets. In conclusion, targeted broadband UVB produces similar clinical responses to targeted NB-UVB in the treatment of the non-segmental type of vitiligo. nan To compare the efficacy of combined tacrolimus and 308-nm excimer laser therapy vs 308-nm excimer laser monotherapy in treating vitiligo.
                Comparative, prospective, randomized, intraindividual study.
                Fourteen patients, aged 12 to 63 years, with Fitzpatrick skin types II to IV.
                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.
                Treatment efficacy, which was blindly evaluated by 2 independent physicians by direct and polarized light photographs taken before and after treatment.
                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.
                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. Surgical techniques have recently been introduced for patients with vitiligo. Randomized controlled trials have not been performed.
                To compare the efficacy and side-effects of two surgical methods (suction blister vs. thin split-thickness graft technique) for the treatment of vitiligo.
                Three suction blisters, approximately 0.8 cm in diameter, made with a special tool attached to a vacuum extractor, which were converted to erosions by removal of the roofs of the bullae, and one round erosion of approximately the same diameter, made using a silver knife, were created. One roof of a blister and two cutaneous thin split-thickness grafts taken from the gluteal region were transferred onto recipient vitiliginous areas; one was left alone. The results were evaluated by one non-blind and two blind observers bimonthly during the 3-month follow-up period.
                Repigmentation rates were 25-65% in the suction blister technique and 90% in the thin split-thickness graft technique (P < 0.001).
                The thin split-thickness graft technique is superior to the suction blister technique in treating vitiligo. 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.
                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.
                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.
                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.
                Application of tacalcitol ointment in combination with twice-weekly NB-UVB phototherapy is an effective alternative treatment for patients with generalized vitiligo.
This review has found some evidence from individual studies to support existing therapies for vitiligo, but the usefulness of the findings is limited by the different designs and outcome measurements and lack of quality of life measures. There is a need for follow-up studies to assess permanence of repigmentation as well as high quality randomised trials using standardised measures and which also address quality of life.
