Introduction: Vitiligo is a common depigmenting skin disorder. This work is performed to systematically evaluate the efficacy and safety of fire needles combined with 308 nm excimer laser therapy in treating vitiligo., Methods: We searched the PubMed, EMBASE, Cochrane Library, Web of Science, CNKI, Wanfang, and VIP databases. Randomized controlled trials (RCTs) on fire needles combined with 308 nm excimer laser therapy with 308 nm excimer laser therapy alone for vitiligo were included. The Cochrane Collaborative Network Tool was used to assess the risk of bias. Statistical analysis was completed using RevMan5.3 software and Stata 15.0 software. The GRADE system was used to evaluate the quality of evidence for outcomes., Results: In this study, 10 RCTs and 1333 patients were included. The results showed that compared with 308 nm excimer laser therapy alone, fire needle combined with 308 nm excimer laser therapy is more effective in improving clinical effective rate (RR = 1.36, 95% CI [1.24, 1.50], p < 0.00001), serum CD4+ level (MD = 3.12, 95% CI [2.50, 3.74], p < 0.00001), CD4+/CD8+ ratio (MD = 0.24, 95% CI [0.09, 0.39], p = 0.001), and quality of life measured by the Dermatology Life Quality Index (DLQI) (MD = 3.76, 95% CI [3.33, 4.19], p < 0.00001), and reducing the Vitiligo Area Score Index (VASI) (MD = -5.47, 95% CI [-6.56, -4.37], p < 0.00001). The reported adverse events, including redness, swelling, pain, blisters, and itching, were controllable, and all these events were well tolerated., Conclusion: The current evidence indicates that fire needle combined with 308 nm excimer laser therapy is effective and safe for vitiligo. However, owing to the suboptimal quality of the included studies, more high-quality and large-scale RCTs are needed for comprehensive analysis and further validation., (© 2024 The Authors.

Vitiligo is considered an autoimmune disease, and its treatment is challenging. We assessed and compared the effect of fractional erbium:yttrium-aluminum-garnet (Er:YAG) laser-assisted delivery of platelet-rich plasma versus microneedling (Mn) with platelet-rich plasma (PRP) in enhancing skin repigmentation in localized stable vitiligo patients. In total, 40 patients with localized stable vitiligo were selected in a random manner into two similar groups (20 each). Group (A) was subjected to fractional Er:YAG laser combined with platelet-rich plasma and Group (B) was subjected to microneedling combined with platelet-rich plasma. The procedure was repeated every 2 weeks for up to 6 months. Each individual was assessed clinically utilizing Vitiligo Area Scoring Index (VASI). Fractional Er:YAG + PRP group achieved better pigmentation100% (excellent 30%, very good 15%, good 30% and satisfactory 25%) which is comparable to Mn + PRP where 80% of cases demonstrate repigmentation (20% very good, 10% good and 50% mild). When comparing the VASI scores for both groups after therapy to the baseline VASI, there was a statistically significant decrease [p = 0.001 for group(A) and 0.003 for group(B)]. Regarding the treatment side effects, there was significantly (p = 0.048) side effects among cases treated with microneedling group(B) (25%) than those fractional Er:Yag laser therapy group(A) (5%). Both forms of therapy demonstrated induction of repigmentation of vitiligo, but fractional Er:YAG laser efficacy is greater when combined with platelet-rich plasma.Clinical trials.gov identifier: NCT05511493., (© 2024.

Background: The total glucoside of paeony (TGP) is recognized for its immunomodulatory properties and anti-inflammatory effects. This study evaluates the efficacy of TGP combined with oral mini-pulse therapy (OMP) and narrow-band ultraviolet B (NB-UVB) in treating active nonsegmental vitiligo (NSV)., Materials and Methods: The combination therapy was contrasted against those from a group treated solely with OMP and NB-UVB. Data from 62 patients undergoing TGP combination treatment and 55 without were analyzed over a 3-month period. After 6 months, the differences in recurrence rate were investigated by follow-up., Results: The findings indicate that integrating TGP may yield superior outcomes compared to OMP + NB-UVB alone. Moreover, the patient's oxidative stress makers were significantly reduced after the treatment. The majority of patients in the TGP cohort exhibited enhanced skin pigmentation over the duration. Notably, no increase in side effects or recurrence was observed in this group. Especially, patients with vitiligo on their head and neck experienced pronounced improvements., Conclusion: The efficacy of the combination treatment group was better than that of the control group at 2 and 3 months, and there was no difference in recurrence rate and side effects, suggesting that TGP may continue to show efficacy in NSV for a longer period of time by reducing the level of oxidative stress, and is especially suitable for patients with head and neck lesions., (© 2024 The Author(s).

Background: In previous studies, the 308-nm light-emitting diode (LED) has been proven safe and effective for treating vitiligo. However, direct comparisons between the 308-nm LED and 308-nm excimer lamp (308-nm MEL) for the treatment of vitiligo are lacking., Objective: To compare the efficacy of the 308-nm LED and 308-nm MEL for treating nonsegmental stable vitiligo., Patients and Methods: This randomized controlled trial was conducted between January 2018 and August 2023. Enrolled patients were randomly assigned to either the 308-nm LED or the 308-nm MEL groups, both receiving 16 treatment sessions. Adverse events that occurred during the treatment were documented., Results: In total, 269 stable vitiligo patches from 174 patients completed the study. A total of 131 lesions were included in the 308-nm LED group, and 138 lesions were included in the 308-nm MEL group. After 16 treatment sessions, 38.17% of the vitiligo patches in the 308-nm LED group achieved repigmentation of at least 50% versus 38.41% in the 308-nm MEL group. The two devices exhibited similar results in terms of efficacy for a repigmentation of at least 50% (p = .968). The incidence of adverse effects with the two phototherapy devices was comparable (p = .522)., Conclusions: Treatment of vitiligo with the 308-nm LED had a similar efficacy rate to the 308-nm MEL, and the incidence of adverse effects was comparable between the two devices., (© 2024 John Wiley & Sons A/S.

Background/purpose: Existing phototherapies are ineffective for treating patients with vitiligo with complete leukotrichia. We compared the efficacy of reverse perilesional irradiation, during which only the lesional areas are covered, with conventional narrowband ultraviolet B (NB-UVB) home phototherapy for repigmentation of non-segmental vitiligo in patients with complete leukotrichia., Methods: This was a 12-week, open-label, double-arm, multicenter clinical trial, with a total of 121 patients with non-segmental vitiligo who were randomly divided into two groups (both received topical tacrolimus): the conventional NB-UVB irradiation (CI) and reverse perilesional NB-UVB irradiation (RI) groups., Results: A statistically significant difference in improvement from baseline was observed in the RI group compared with the findings in the CI group (-30.8% ± 11.8% vs. -25.5% ± 11.05%, respectively [p = .010]; pair-wise comparison p = .900 at week 4, p = .104 at week 8, and p = .010 at week 12). At week 12, the average percentage change from baseline of leukotrichia in the irradiation area significantly decreased from 100% to 82.2% ± 13.65% in the RI group, and from 100% to 88.7% ± 9.64% in the CI group (p = .027). Adverse events were minor, including desquamation, dryness, erythema, and blisters. No severe or lasting side effects were observed during the study., Conclusion: RI mediated better repigmentation of vitiligo with complete leukotrichia than CI., (© 2024 John Wiley & Sons A/S.

We have discovered that human vitiligo patients treated with narrow-band UVB (NBUVB) demonstrated localized resistance to repigmentation in skin sites characterized by distinct cellular and molecular pathways. Using immunostaining studies, discovery-stage RNA-Seq analysis, and confirmatory in situ hybridization, we analyzed paired biopsies collected from vitiligo lesions that did not repigment after 6 months of NBUVB treatment (non-responding) and compared them with repigmented (responding) lesions from the same patient. Non-responding lesions exhibited acanthotic epidermis, had low number of total, proliferative, and differentiated melanocyte (MC) populations, and increased number of senescent keratinocytes (KCs) and of cytotoxic CD8+ T cells as compared with responding lesions. The abnormal response in the non-responding lesions was driven by a dysregulated cAMP pathway and of upstream activator PDE4B, and of WNT/β-catenin repigmentation pathway. Vitiligo-responding lesions expressed high levels of WNT10B ligand, a molecule that may prevent epidermal senescence induced by NBUVB, and that in cultured melanoblasts prevented the pro-melanogenic effect of α-MSH. Understanding the pathways that govern lack of NBUVB-induced vitiligo repigmentation has a great promise in guiding the development of new therapeutic strategies for vitiligo., (© 2024 John Wiley & Sons A/S.

This study aimed to investigate the effects and safety of 308 nm excimer laser (308 nm EL) and tacrolimus ointment (TO) in the treatment of facial vitiligo (FV). We searched Cochrane Library, PUBMED, EMBASE, CNKI, and WANGFANG from inception to June 1, 2023. Outcomes included overall response rate (ORR), total adverse reaction rate (TARR), recurrence rate at 3-month (RR-3) and recurrence rate at 6-month (RR-6). The outcome data were presented as odds ratios (OR) with 95% confidence intervals (CI). The risk of bias was assessed by Cochrane risk-of-bias tool and data analysis was performed by RevMan 5.4 software. This study included a total of 19 trials involving 2085 patients. When comparing 308 nm EL monotherapy with 308 nm EL plus TO, significant differences in the ORR (OR = 4.29, 95% CI [2.97, 6.19], I 2  = 0%, P < 0.001), RR-3 (OR = 0.18, 95% CI [0.05, 0.69], I 2  = 0%, P = 0.01), and RR-6 (OR = 0.38, 95% CI [0.14, 1.03], I 2  = 39%, P = 0.06) were found between the two managements. When comparing TO monotherapy with TO plus 308 nm EL, its results showed significant differences in the ORR (OR = 4.21, 95% CI [2.90, 6.11], I 2  = 0%, P < 0.001), TARR (OR = 0.42, 95% CI [0.22, 0.81], I 2  = 4%, P = 0.009), and RR-3 (OR = 0.32, 95% CI [0.01, 8.03], P = 0.49) between the two modalities. The results of this study suggest that the combination of 308 nm EL and TO is more effective than either treatment alone for the treatment of FV., (© 2024.

Background: Narrowband ultraviolet B (NB-UVB) phototherapy promotes stability and repigmentation in vitiligo. No studies have compared targeted NB-UVB with whole-body NB-UVB in treatment of acral vitiligo., Objectives: This randomized split-body study compared whole-body NB-UVB with targeted NB-UVB in inducing stability and repigmentation in acral vitiligo., Methods: Thirty-two patients with bilaterally symmetrical acral vitiligo lesions (distal to elbows and knees) were recruited. Patients received whole-body NB-UVB treatment, with one hand and one foot shielded until elbow and knee, followed by targeted NB-UVB treatment on the shielded side. Patients were assessed at 4-week intervals for 24 weeks using Vitiligo Disease Activity (VIDA) score, Vitiligo Skin Activity Score (VSAS), Vitiligo Area Scoring Index (determined through fingertip method, using the method to calculate facial-VASI) and degree of repigmentation., Results: After 12 weeks, 87.5% of patients achieved a VIDA score of 3, with none having active disease at 24 weeks. Over 50% repigmentation was observed in 42.2% and 37.5% of limbs in whole-body and targeted groups, respectively (p = .95). No improvement in F-VASI scores of hands and feet (distal to wrist and ankles) was noted with either modality over the 24-week period., Conclusion: Our study showed comparable repigmentation rates between whole-body and targeted NB-UVB groups. Limited effectiveness of phototherapy in repigmentation of hands and feet underscores an important therapeutic gap., (© 2024 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Laser hair removal is a commonly used method in dermatology which is based on selective thermolysis and utilizes the appropriate wavelength, pulse width, and energy density to damage hair follicles. Given the prevalence of skin diseases such as psoriasis, dermatitis, and vitiligo, and the increasing popularity of laser hair removal, the aim of this study was to investigate the safety of laser hair removal in individuals with skin diseases. This retrospective study was conducted at the laser department of Razi Hospital on 99 patients who underwent laser hair removal. The exacerbation of disease after laser therapy was significantly associated with active skin disease ( p  = .021) and laser treatment at the site of the disease ( p  < .001). The incidence of Koebner phenomenon was significantly associated with age ( p  = .017) and the number of sessions with the ND-YAG device ( p  = .034). It is crucial to exercise caution when performing laser treatment on individuals with active skin disease and to avoid treating the affected area were possible. If necessary, it is recommended to delay laser treatment until the disease is under control for patients with active skin disease or those who wish to receive laser treatment at the site of the disease.

Objective: To probe the clinical effect of stem cell transplantation in combination with 308-nm excimer laser therapy for vitiligo and to analyze its value in clinical application., Methods: A total of 56 patients with stable non-segmental vitiligo in different parts who were not cured by other therapies visiting our hospital from March 2019 to December 2021 were enrolled as study subjects. They were treated by stem cell transplantation combined with 308-nm excimer laser therapy. The treatment efficacy was observed and analyzed., Results: Among the 56 patients, 38 (67.85%) and 49 (87.5%) patients were cured at 6 and 12 months after treatment, respectively., Conclusion: Stem cell transplantation combined with 308-nm excimer laser therapy for vitiligo achieves significant efficacy, with the cure rate far superior to that of other therapies for vitiligo. The therapy is worthy of popularization in the clinic., (© 2023 The Authors. Journal of Cosmetic Dermatology published by Wiley Periodicals LLC.)

In the recent decades, prostaglandins were recommended as a new therapeutic modality of stable vitiligo with promising efficacy. Therefore, we designed the current work to compare the significance of two different subtypes of prostaglandins [prostaglandin E2 (PGE2) versus prostaglandin F2 alpha (PGF2α)], assisted with NB-UVB phototherapy, in treatment of stable vitiligo. This study was conducted on 30 patients with stable non-segmental vitiligo. Three approximately similar vitiliginous areas were chosen in each patient and assigned into 3 groups. Each group treated with intradermal injection of either PGE2 (group I), PGF2α (group II), or saline as placebo (group III) at frequency once/week for 12 weeks. Concomitantly, all groups received NB-UVB phototherapy twice weekly for 3 months. The outcomes of this study discovered that the therapeutic efficacy of intradermal injection of either PGE2 or PGF2α assisted with NB-UVB phototherapy was comparable with non-significant difference between them in spite of being significantly higher than NB-UVB alone. However, there were a significantly earlier onset of repigmentation and higher degree of satisfaction regarding areas treated with PGE2 than those treated with PGF2α. In conclusion, both PGF2α and PGE2 intradermal injection could be considered as quite simple and affordable techniques in the treatment of stable vitiligo with no reported side effects and good patient satisfaction., (© 2023.

Background: Vitiligo is a cosmetically concerning common disorder of depigmentation. Narrowband Ultraviolet B (NB-UVB) phototherapy is a well-established mode of treatment for vitiligo. Microneedling is a simple method that has been used for vitiligo treatment in adjunct with NB-UVB and has been shown to induce repigmentation in a few studies; however, there is limited study in the literature., Aims: To compare the efficacy of NB-UVB alone versus NB-UVB in conjunction with microneedling in patients of stable vitiligo., Methods: Thirty patients of non-segmental vitiligo with patches tending toward symmetry, stable for at least 6 months were included. Patches on right side of body (side A) were subjected to both microneedling every 2 weeks and NB-UVB three times a week, while patches on left side of body (side B) were subjected to NB-UVB alone thrice weekly for 4 months or till complete resolution of lesions whichever was earlier. Patients were followed up for another 2 months. Response was assessed by photographic record and Vitiligo Area Severity Index (VASI score) calculated at baseline and every month for 6 months., Results: The mean VASI score improvement in both the groups as compared to baseline was statistically significant (p-value < .01). However, the difference in mean VASI scores between the two groups was not statistically significant (p-value = .17)., Conclusion: NB-UVB is an effective modality for treatment of vitiligo, but there is no additional benefit of combining microneedling with it., (© 2022 John Wiley & Sons A/S.

Bimatoprost ophthalmic solution 0.03% (PGF2α analogues) combined with narrowband ultraviolet B (NB-UVB) was reported to be an effective treatment for vitiligo. To investigate the efficacy and safety of treatment for non-segmental/segmental vitiligo compared among bimatoprost ophthalmic solution 0.01% combined with NB-UVB phototherapy, bimatoprost monotherapy, and placebo. This single-blind randomized controlled study enrolled stable Thai vitiligo patients with at least three similarly sized lesions in the same anatomical area. The treatment duration was 6 months with 1- and 2-month post-treatment follow-ups. The 3 selected lesions on each patient were randomized to receive combination therapy, monotherapy, or placebo. The Vitiligo Area Scoring Index (VASI) was used to evaluate lesion response. Of the 25 initially enrolled subjects, 19 patients were analyzed. There were 13 and 6 non-segmental and segmental vitiligo cases, respectively. Eight and 11 cases had face/neck and non-face/neck lesions, respectively. Non-segmental vitiligo and non-face/neck vitiligo patients in the combination group had significant improvement in VASI score at 3 months, 6 months, and at the 2-month follow-up. No side effects were observed/reported. Bimatoprost combination therapy was shown to be safe and effective for treating Thai patients with non-segmental vitiligo in non-face/neck areas of the body., (© 2023. The Author(s).)

Vitiligo is a chronic autoimmune disease characterized by the T helper 1 (Th1) cytokine-driven immune destruction of melanocytes (MCs). Although narrowband ultraviolet B (NBUVB) phototherapy has been proven to be an effective therapeutic option, the repigmentation response to that phototherapy varies greatly in different vitiligo patients. Here, we demonstrate that there is an increase of NBUVB-induced cellular senescence in vitiligo MCs exposed to Th1 cytokine interferon γ (IFNγ) and/or tumor necrosis factor α (TNFα) in lesional vitiligo skin from poor responders who had undergone NBUVB phototherapy. Supplementation with exogenous recombinant human stem cell factor (rhSCF) in the culture medium as well as the lentiviral vector-mediated overexpression of cKIT could prevent the MCs from the IFNγ/TNFα-accelerated cellular senescence. Mechanistic studies indicated that the reduced ratio of membrane-bound KIT (mKIT) to the soluble form of KIT (sKIT) is directly related to the cellular senescence of vitiligo MCs following exposure to IFNγ and TNFα. Furthermore, the matrix metalloprotease 9 (MMP9) inhibitor GM6001 attenuates the production of sKIT via the suppression of cKIT ectodomain shedding. Altogether, our study indicates that the presence of Th1 cytokines IFNγ and/or TNFα in the epidermal milieu might impair the repigmentation response of vitiligo patients to NBUVB phototherapy., Competing Interests: Conflict of interest The authors declare that there is no conflict of interest regarding the publication of this paper., (Copyright © 2023 Elsevier B.V.

Background: Vitiligo is an autoimmune dermatological disease characterized by hypopigmented macules. Treatments include topical agents, phototherapy, and laser therapies. Different lasers should be individually chosen regarding location, extent, activity of the disease., Aims: This article aims to demonstrate how blue LED is effective and safe, as its wavelength is very close to the UV spectrum (415 nm vs. 400 nm), but, unlike UV therapy, blue LED have not shown any long-term cancerogenic side effects., Patients/methods: We treated 30 patients affected by vitiligo localized on different anatomical areas with blue light-emitting diodes., Results: Complete repigmentation occurred in 75.33% of treated patients (22 out of 30 patients, 14 males, and 8 females). Partial repigmentation occurred in the remaining patients., Conclusions: Blue LED light may be a safe and well-tolerated way to induce repigmentation in patients affected by vitiligo., (© 2022 The Authors.

Vitiligo is acquired depigmentation due to multiple factors. Vitamin D in skin, through its receptors (VDR), regulates cell growth, differentiation, immune response and exerts both stimulatory and protective effects on melanocytes. The gene sequence encoding VDR has polymorphic forms such as ApaI and TaqI that may affect vitamin D actions. Narrowband ultraviolet B (NB-UVB) phototherapy became the mainstay of vitiligo treatment because of its efficacy and little side effects. The current work aimed at evaluating the possible association between VDR gene polymorphisms (TaqI and ApaI) and susceptibility of vitiligo and if they could be predictors of response to NB-UVB phototherapy in Egyptian vitiligo patients. 100 vitiligo patients indicated for NB-UVB phototherapy and 100 healthy age and sex matched controls were included. All participants were subjected to history taking, general and dermatological examinations, and VDR ApaI and TaqI gene polymorphisms analysis by PCR-RFLP. The patients received NB-UVB 3times per week for 6 months then revaluated. There was significant increase in Aa genotype of ApaI polymorphism in patients associated with significant increase in vitiligo activity. 66% of patient showed variable degrees of response to NB-UVB. The responders significantly had AA genotype of ApaI polymorphism. TaqI polymorphism showed nonsignificant effects on vitiligo susceptibility and response to NB-UVB. A allele of ApaI was significant independent predictor of NB-UVB phototherapy responders. VDR gene polymorphism (ApaI) may share in vitiligo pathogenesis and response to NB-UVB. Knowing the genetic background of the patient helps individualization of treatment to get better results., (© 2022. The Author(s).)

Improved repigmentation of generalized vitiligo in skin types IV-VI has been reported in clinical response to combined therapy with apremilast and narrowband (NB)-UVB; however, tissue responses to combined therapy versus NB-UVB monotherapy have not been elucidated. We compared the change from baseline in cellular and molecular markers in vitiligo skin after combined therapy versus NB-UVB monotherapy. We assessed lesional and nonlesional skin samples from enrolled subjects and evaluated for immune infiltrates, inflammatory, and melanogenesis-related markers which were compared across different treatment groups. Combined therapy resulted in significant reduction of CD8 + T cells and CD11c + dendritic cells, downregulation of PDE4B and Th17-related markers, and upregulation of melanogenesis markers. This study was limited to small sample size, skin types IV-VI, and high dropout rate. Our molecular findings support the clinical analysis that apremilast may potentiate NB-UVB in repigmentation of generalized vitiligo in skin types IV-VI., (© 2022.

Vitiligo is the most common depigmenting disorder to which both genetic and environmental factors contribute. The aim of the current work was to evaluate the relationship between polymorphisms of the gene nuclear receptor subfamily 1 Group H member 3 (NR1H3) and the risk of vitiligo and phototherapy effects in the Chinese Han population. Two independent samples were enrolled to form the discovery set (comprised of 1668 nonsegmental vitiligo [NSV] patients and 2542 controls) and the validation set (comprised of 745 NSV patients and 1492 controls). A total of 13 tag single nucleotide polymorphisms (SNPs) were genotyped in the samples from the discovery stage. SNPs that achieved nominal significance were validated in another independent sample set. The serum level of NR1H3 protein was assayed using enzyme-linked immunosorbent assay kits in the validation set. Genetic association analysis was carried out at allelic and genotypic levels. The therapeutic effects of significant SNPs were examined in the validation set. The SNP rs3758672 was significantly associated with NSV. The A allele was correlated with NSV risk and poorer therapeutic effects. The A allele was strongly correlated with the increased level of serum NR1H3 in both controls and patients. In summary, SNP rs3758672 in NR1H3 was significantly associated with both disease susceptibility and individualized therapeutic effects of NSV in study participants with Han Chinese ancestry., (© 2023.

Context: Narrowband ultraviolet B (NBUVB) phototherapy is the standard treatment for chronic stable vitiligo, but its efficacy, when used alone, is often unsatisfactory., Objective: The study evaluated the efficacy of surrounding needling with acupuncture needles in combination with NBUVB phototherapy for lesions on different body parts of patients with chronic stable vitiligo., Design: The research team designed a 12-week, randomized, open-label, prospective, intra-individual, comparative clinical trial., Setting: The study took place in the Department of Dermatology at Shin-Kong Wu Ho-Su Memorial Hospital in Taiwan., Participants: Participants were patients at the hospital, aged 20-80 years, with chronic stable nonsegmental vitiligo. The lesions on both sides of their bodies had the same baseline conditions. Nine patients with 14 pairs of lesions (n = 28) were included in the study, and eight participants with 13 pairs of lesions (n = 26) successfully completed the study., Intervention: Vitiligo lesions in the intervention group were treated with surrounding needling combined with NBUVB phototherapy, whereas the control group received NBUVB phototherapy only., Outcome Measures: The primary outcome was evaluated at Week 12 using the modified Vitiligo Area Scoring Index (VASI), which focuses on local depigmentation only without multiplication by body surface area, and the testing used the Wilcoxon signed-rank test. A higher VASI score indicates more severe vitiligo. Pain was rated postintervention, after completion of all treatments., Results: At baseline, the modified VASI score in both groups was 93.07 ± 4.62. Postintervention, this score in the intervention group improved to 78.46 ± 15.24, with a significant difference between baseline and postintervention (P = .007), and in the control group, the score improved to 91.92 ± 6.67, with no significant difference having occurred (P = .317). A statistically significant difference was found between the intervention group and the control group in the change in scores postintervention (P = .007)., Conclusion: Surrounding needling in combination with NBUVB phototherapy may be a promising treatment for chronic stable nonsegmental vitiligo. Future studies with larger sample sizes and long-term follow-up are warranted.

Objectives: To explore the short- and long-term effects of UVB phototherapy preceding a fractional CO 2 laser-UVB protocol in patients with resistant nonsegmental vitiligo., Materials and Methods: This single-center, prospective, split-face/body, evaluator-blinded study included adult patients with stable vitiligo refractory to conventional treatments. Two symmetrical lesions were selected. Phototherapy was delivered with one side covered, until minimal erythema. Within 3 days, 31-month-apart sessions of laser were performed on both sides. After each laser session, phototherapy was resumed three times weekly, with all lesions uncovered, until 8 weeks after the last laser session. At baseline, at the end of treatment, and 5 years later, a Mean Improvement Score by Physician (MISP) and a patient satisfaction 10-point visual analog score (VAS) were recorded., Results: Ten patients (8 women and 2 men) were included; their mean age was 32.9 years; phototype III was predominant; the mean duration of vitiligo was 3 years. At the end of treatment and 5 years later, scores of lesions treated with UVB-CO 2 -UVB (mean MISP 3.0 and 2.9, mean ΔVAS 4.5 and 3.9, respectively), were higher than those of lesions treated only with CO 2 -UVB (mean MISP 2.5 and 2.4, mean ΔVAS 4.1 and 3.6, respectively). After 5 years, one patient lost his partial response and two patients developed light hyperpigmentation on both sides., Conclusion: Exposure to UVB before CO 2 -UVB explains the higher scores as it was the only variable between the two sides. It may improve the response of resistant lesions with a constantly sustained result over 5 years., (© 2022 Wiley Periodicals LLC.)

Background: The adherence to a narrowband ultraviolet B (NB-UVB) treatment plan is derived, in large part, from the patient's skin tolerance to the phototherapy dose. At present, the initial and first-month incremental phototherapy doses are determined prior to treatment initiation based on the patient's Fitzpatrick skin phototyping., Objectives: To identify variables that predict adherence to NB-UVB first-month treatment dosage plan., Methods: Charts of 1000 consecutive patients receiving NB-UVB at a hospital-based phototherapy unit were retrospectively analyzed. We included patients receiving NB-UVB for atopic dermatitis, psoriasis, vitiligo, and mycosis fungoides. The first-month NB-UVB treatment plan was determined based on the patient's Fitzpatrick phototype. Adherence to treatment was defined as receiving at least 80% of the planned first-month cumulative dose. We compared adherent vs. non-adherent patient groups for age, sex, Fitzpatrick phototype, presence of freckles, nevus count category, and type of dermatological disease., Results: The study included 817 eligible patients, mean age 40 (2-95) years; 54% men; 32% had Fitzpatrick phototype I-II. Distribution by diagnosis was atopic dermatitis (29%), psoriasis (27%), vitiligo (23%), and mycosis fungoides (21%). Adherence to NB-UVB treatment plan was observed in 71% of patients. Adherence decreased with age, with 7% decrease per year (P = 0.03) and was higher among mycosis fungoides patients (77.3%) compared to all other diagnoses (69.8%; P = 0.02)., Conclusions: Adherence to NB-UVB treatment may be related to age and diagnosis. Fitzpatrick phototype-based first-month treatment plans should be modified accordingly.

Vitiligo is a chronic treatment-resistant autoimmune disorder characterized by circumscribed depigmented maculae. This study was conducted to evaluate the efficacy and safety of tofacitinib combined with narrowband ultraviolet B (NB-UVB) phototherapy for refractory nonsegmental vitiligo. Fifteen patients with nonsegmental vitiligo resistant to conventional therapies were administered oral tofacitinib at 5 mg twice daily plus topical halometasone cream, tacrolimus 0.1% ointment, or pimecrolimus cream twice daily and NB-UVB three times per week for 16 weeks. The control group comprised 19 patients with nonsegmental vitiligo treated with topical drugs plus NB-UVB same as the combination group. Treatment efficacy was measured by the percentage of repigmentation of vitiligo lesions at 4th, 8th, 12th, and 16th week after beginning treatment. From 8th week, the repigmentation level was significantly higher in the combination group than in the controls. From fourth week, the response rate was significantly higher in the combination group than in the controls. Only one patient in the combination group reported mild pain in the hand and foot joints, but the pain subsided with cessation of therapy. No other severe adverse effects occurred. So, tofacitinib in combination with NB-UVB phototherapy may be an effective and safe alternative modality for refractory vitiligo., (© 2022 Wiley Periodicals LLC.)

Background: A light emitting diode (LED), with a wavelength of 308 nm, has been utilized in the dermatologic treatment of vitiligo., Objectives: We investigated the efficacy and safety of 308-nm LED for use in the treatment of vitiligo., Methods: We conducted a retrospective study of 70 stable-stage vitiligo patients (with a total of 99 lesions) who received 308-nm LED treatment at the Institute of Dermatology, Chinese Academy of Medical Sciences and Peking Union Medical College from June 2018 to June 2020. Treatment efficacy was evaluated after 8 treatment sessions, 16 treatment sessions, and the final treatment session, to estimate the percentage of re-pigmentation in the treated area. The Kruskal-Wallis test was used for data analysis., Results: Based on the final treatment session analysis of all 99 lesions, 0 lesions showed no response, 21 lesions showed poor response, 29 lesions showed moderate response, 23 lesions showed good response, and 26 lesions showed excellent response. The efficacy rate was 49.49%, and there was a significant correlation between the six distinct anatomical regions treated and re-pigmentation grade (χ 2  = 13.419, p = .009). Among these regions, facial lesions showed the best response to treatment, while the hands and feet lesions showed the poorest response., Conclusions: The clinical efficacy of 308-nm LED treatment is limited based on the treatment area. It demonstrated significant practical application in the treatment of vitiligo., (© 2022 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background: Many treatment modalities have been used to stabilize vitiligo and induce repigmentation. Several methods were used to monitor the color changes inside the treated lesions such as spectroscopes and colorimeters that measure the melanin index inside the lesion., Objective: To study whether the colorimeter and point counting technique can be used as objective methods in monitoring vitiligo lesions during treatment with Nb-UVB., Methods: Twenty randomly chosen patients with non-segmental vitiligo were enrolled in this interventional study. Vitiligo disease activity score was recorded in each patient. Patients received Nb-UVB three times per week for 6 months. Two lesions were chosen in each patient, and each lesion was assessed for size using point counting technique and degree of color using the Dermacatch ® at the beginning of the treatment and evaluated for changes in color and size every 4 weeks till the end of the treatment., Results: After 6 months of treatment, regarding the lesion size, 90% of lesions showed variable degrees of repigmentation and 10% showed increase in size, indicating increased activity of the disease, and regarding to color changes. We noticed that after one month of Nb-UVB treatment, there is marked increase in MI measurements in many lesions before any clinical improvement appeared, while at the end of treatment, inside the lesion; 95% showed an increase in melanin index and 5% showed no elevation. While the color changes outside the lesion showed 75% of lesions increased in melanin index, 15% remained unchanged and 10% of the lesions showed decrease in melanin index., Conclusion: Colorimeter was able to detect change in color after only one month of treatment before it was clinically apparent which means that it can be used as a prognostic tool., (© 2021 Wiley Periodicals LLC.)

Narrowband ultraviolet B (NBUVB) phototherapy is an effective therapeutic option for generalized vitiligo. Previous reports showed the potential benefit of minocycline to stop disease progression in vitiligo. Meanwhile, minocycline has antioxidative, anti-inflammatory, and immunomodulating properties. There is no clinical study combining oral minocycline and NBUVB for treating generalized vitiligo. This study aims to compare the efficacy and safety of the combination treatment of NBUVB plus oral minocycline with NBUVB alone in generalized vitiligo. A randomized, double-blinded, placebo-controlled pilot study was conducted. Patients were randomly treated with either combined oral minocycline 100 mg per day plus NBUVB phototherapy or placebo plus NBUVB. All patients recieved NBUVB two times per week, for 12 weeks. The outcomes were assessed using Vitiligo Area Scoring Index score (VASI) percent change, quartile grading scale (QGS) of repigmentation, and Vitiligo Disease Activity Index (VIDA) score. Fourteen generalized vitiligo patients were included, and seven cases were assigned in each group. At week 12, the mean VASI score was decreased by 28.87% (24.15) in the minocycline group compared to 27.26% (7.98) in placebo group (p = 0.886). No significant difference was observed between both treatment modalities in QGS of repigmentation and mean VIDA score change. Two of the seven patients (29%) receiving minocycline developed hyperpigmentation, dark-brown and muddy brown discoloration, which was only confined to some vitiliginous patches. In conclusion, combination therapy with oral minocycline does not enhance the efficacy of NBUVB in generalized vitiligo. Due to the high incidence of drug-induced skin hyperpigmentation, minocycline plus NBUVB should be avoided., (© 2022 Wiley Periodicals LLC.)

Background: Monochromatic excimer light (MEL) is a safe and effective treatment for localized stable vitiligo. Previous reports of the combination of platelet-rich plasma (PRP) with narrowband ultraviolet B (NB-UVB) or excimer laser yielded conflicting results., Aims: This prospective, self-controlled, randomized, comparative study aimed to assess whether the addition of PRP to MEL therapy would be of an additive benefit in the treatment for localized stable vitiligo. Patients/Methods The current study included 36 patients with at least 2 more or less symmetrical patches of localized stable vitiligo (72 patches). For each patient, each of the 2 vitiligo patches was randomly assigned to receive either MEL therapy (twice weekly) with bi-weekly intradermal PRP (group A) or MEL therapy alone (group B) for a maximum of 4 months or till complete repigmentation. The degree of repigmentation was categorized as absent (0%), poor (1-25%), moderate (26-50%), good (51-75%), or excellent (>75%). Patients were asked about their level of satisfaction (not satisfied at all, partially satisfied, satisfied, or completely satisfied). Side effects were recorded, and follow-up for 3 months was done., Results: No statistically significant difference was observed between the 2 groups regarding the degree of repigmentation, the patients' level of satisfaction, and the frequency of side effects (p = 0.504, 0.490, and 0.912, respectively). At the end of the follow-up period, recurrence was observed in only 3 patients., Conclusions: The current study showed no statistically significant difference between using MEL alone or with intradermal PRP in the treatment for localized stable vitiligo., (© 2021 Wiley Periodicals LLC.)

Pediatric vitiligo is often challenging to treat. Children with vitiligo experience stigma, bullying, and emotional distress. The long-term outcome of therapeutics used to treat pediatric vitiligo has been poorly documented in the literature. It is, therefore, hard to counsel patients on the expected long-term results of therapy. We sought to address outcomes in pediatric vitiligo treated with a 308-nm laser. An IRB-exempt chart review was conducted in June of 2016 of children undergoing active 308-nm laser in the first half of 2016. Demographic data, location of disease, therapeutic parameters of the 308-nm laser, and outcomes were recorded at that time. In 2021, the long-term outcomes were analyzed through chart review addressing pigmentation retained at later office visits. Initial repigmentation was noted in 86.7% of the face, 80% of the body, and 61.7% of the extremities. An average of 3.38 years of follow-up was recorded. Scoring extent of vitiligo using 18 site-scoring was helpful in identifying individuals who are less likely to respond to 308-nm laser, but needs broader evaluation. During that time, repigmentation was noted to be retained in 80% of facial, 40% of the body, and 20% of extremity lesions. Pediatric vitiligo responds well to the 308-nm laser, with the best retention of repigmentation for facial lesions. Patients and parents should be counseled on the likelihood of long-term retention of repigmentation and regarding the need for the ongoing management of vitiligo even after repigmentation is initially achieved after 308-nm laser therapy.

Background: NB-UVB has long been the vitiligo management pillar with capability of achieving the main treatment outcomes; repigmentation and stabilization. Its stabilizing effect in dark skin has been debatable. However, randomized controlled trials regarding NB-UVB ability to control disease activity are lacking., Purpose: To assess stabilizing effect of NB-UVB in comparison to systemic corticosteroids, the mainstay in vitiligo stabilization, in skin photo-types (III-V)., Methods: This is a multicenter, placebo-controlled, randomized, prospective study. Eighty patients with active nonsegmental vitiligo (NSV) (Vitiligo disease activity (VIDA) ≥2) were randomized to either NB-UVB and placebo (NB-placebo) or NB-UVB and dexamethasone oral mini-pulse (OMP) therapy (NB-OMP) for 6 months. Sixty four patients completed the study, 34 in the NB-OMP group and 30 in the NB-placebo group. Patients were evaluated fortnightly according to presence or absence of symptoms/signs of activity., Results: In spite of earlier control of disease activity observed in the NB-OMP group, it was comparable in both groups by the end of the study period. Disease activity prior to therapy, but not extent, was found to influence control of activity in both groups. Thus, NB-UVB is a safe sole therapeutic tool in vitiligo management. Not only does it efficiently achieve repigmentation, but also it is a comparable stabilizing tool for systemic corticosteroids in spite of slightly delayed control., Conclusion: NB-UVB is the only well-established vitiligo therapy that can be used solely whenever corticosteroids are contraindicated or immune-suppression is unjustified. Nonetheless, its combination with corticosteroids expedites response and improves compliance., (© 2021 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Vitiligo is a chronic pigmentary skin disorder that results in white, hypopigmented macules and patches. It causes a considerable psychological and emotional burden on the affected individuals and their families. Several therapeutic options have been employed in vitiligo including topical and oral drugs, surgical techniques, and phototherapy which is considered the cornerstone treatment. Different wavelengths and modalities are available, but narrowband UVB (NB-UVB) is considered the safest and the most effective phototherapy alternative. NB-UVB acts on multiple steps in vitiligo pathogenesis, and it is capable of inducing stabilization and repigmentation of vitiligo lesions. Technological advances have led to the development of both new phototherapy devices and new medical and surgical therapeutic options that can be combined with phototherapy to achieve optimal results. There is no standard treatment, and individual patient and disease characteristics should be considered. We review the current evidence in what concerns UVB phototherapy for vitiligo treatment, including novel combination treatments that may help to provide the best care for these patients., (© 2021 John Wiley & Sons A/S.

Background: Although ultraviolet (UV) phototherapy is an effective treatment for vitiligo, its effect on the risk of skin cancer remains controversial., Aim: To investigate the association between UV phototherapy and skin cancer risk in patients with vitiligo., Methods: A systematic review was performed for studies published before 5 May 2021 in the PubMed, Embase, Web of Science and Cochrane Library databases. The primary outcome was the association of UV phototherapy with the risk of skin cancer in patients with vitiligo. A meta-analysis with a random-effects model was conducted., Results: Five retrospective cohort studies covering a total of 228 607 patients with vitiligo (110 038 who had been treated with UV phototherapy and 118 569 patients who had not) were included in the meta-analysis. The risk of nonmelanoma skin cancer [Mantel-Haenszel risk ratio (MHRR) = 0.95; 95% CI 0.44-2.05] and melanoma (MHRR = 1.11; 95% CI 0.33-3.82) did not significantly increase after phototherapy in patients with vitiligo. In the subgroup analysis, we also found no significant association between phototherapy with narrowband UVB phototherapy specifically and risk of skin cancer in patients with vitiligo. There was no significant difference in risk of skin cancer between patients from Europe and those from East Asia and the risk was not affected by the number of narrowband UVB phototherapy sessions., Conclusions: The findings of this systematic review and meta-analysis suggest that UV phototherapy is a safe treatment for vitiligo with no significant risk of skin cancer., (© 2021 British Association of Dermatologists.)

Carboxytherapy has been used in the treatment of autoimmune skin diseases such as psoriasis and morphea. Carboxytherapy has antioxidant effects, and leads to better tissue oxygenation, and release of growth factors. In this article, we decided to evaluate efficacy of combined carboxytherapy and narrowband-ultraviolet B (NB-UVB) compared to NB-UVB alone in the treatment of vitiligo. This is a prospective, split-body double-blind comparative study performed in patients with generalized stable vitiligo in acral areas and extremities referred to dermatology clinic of Afzalipour hospital in Kerman University of Medical Sciences. NB-UVB was performed three times a week in non-consecutive days for 4 months. In each patient, one lesion was randomly treated with carboxytherapy (weekly sessions for total of 16 sessions). Efficacy of treatment was evaluated by percentage of repigmentation of the lesions. Chi-square test and analysis of variance test (ANOVA) were used to compare efficacy of treatment based on demographic features of the patients and clinical features of the lesions, respectively. Twenty-eight patients with mean age of 32.35 ± 7.37 years old completed the study. At the end of the treatment, 37% of the patients in combination therapy group demonstrated more than 75% improvement compared to 0% in the monotherapy group (p = 0.001). There was no significant difference between either demographic features of the patients (age, sex, and skin phototypes) or duration of disease with efficacy of the treatment in both groups. Combination of carboxytherapy with NB-UVB leads to higher percentage of repigmentation and patients' satisfaction compared to monotherapy with NB-UVB., (© 2021 Wiley Periodicals LLC.)

Background: Vitiligo represents a commonly diagnosed autoimmune disease caused by the depletion of epidermal melanocytes. Many subsets of T cells contribute to vitiligo pathogenesis, including resident and circulating memory T cells., Objectives: To analyze the amounts of CD4 + and CD8 + memory T-cell subsets in peripheral blood specimens from vitiligo patients and alterations caused by narrowband ultraviolet B (NB-UVB) phototherapy., Methods: Circulating CD4 + and CD8 + central memory T (T CM ) and effector memory T (T EM ) cell frequencies in 33 patients with non-segmental vitiligo and 16 healthy donors were evaluated by flow cytometry. Related chemokine levels were also detected., Results: Peripheral blood CD4 + T CM and CD8 + T CM counts were markedly reduced in vitiligo cases while they were higher in active vitiligo compared with stable vitiligo cases. Circulating CD8 + T CM frequency in vitiligo was closely related to disease duration. Interestingly, CD4 + T CM and CD8 + T CM frequencies, alongside CXCL9 and CXCL10 amounts in peripheral blood of patients with vitiligo, were significantly decreased after NB-UVB phototherapy., Conclusions: Decreased frequencies of circulating CD4 + T CM and CD8 + T CM by NB-UVB suggest a possible immunosuppressive effect of phototherapy. The chemokines CXCL9 and CXCL10 are the bridge between circulating and skin resident memory T cells. NB-UVB blocks the homing of circulating memory T cells into vitiligo lesions by down-regulating CXCL9 and CXCL10. Targeting the above proteins could provide novel, durable treatment options to cure and prevent flares of this disease., (© 2021 The Authors.

Background: Langerhans cells (LCs) are antigen-presenting cells that are characterized by CD1a and CD207/langerin expression. The disturbance in the communication network among keratinocytes, melanocytes, and antigen-presenting cells may be involved in vitiligo pathogenesis., Aims: The current work aims to detect and quantify LCs in involved skin of patients affected by vitiligo before and after treatment with NB-UVB using CD1a immunohistochemistry, in addition to correlate percentage of LCs with the clinicopathological parameters., Methods: Twenty vitiligo patients and 10 age and sex matched controls were investigated. Patients were received NB-UVB thrice weekly for 12 weeks., Results: There was a significant reduction in LCs percentage in skin affected by vitiligo before treatment in comparison with normal skin. About 65% (13/20) of vitiligo patients responded to NB-UVB, and the liability to respond was correlated with LCs percentage in specimens before treatment. However, there was no statistical difference between specimens before and after treatment regarding LCs percentage., Conclusions: Reduction in LCs in vitiligo may be a sign of active disease and melanocytes destruction. The percentage of LCs affects response to NB-UVB since higher percentage is associated with greater response to therapy. Therefore, modulation of LCs as a type of immunotherapy could be beneficial in improvement of vitiligo., (© 2021 Wiley Periodicals LLC.)
