Abstract
Vitiligo is an autoimmune disease that leads to disfiguring depigmented lesions of skin and mucosa. Although effective treatments are available for vitiligo, there are still some patients with poor responses to conventional treatment. Refractory vitiligo lesions are mostly located on exposed sites such as acral sites and lips, leading to significant life stress. Understanding the causes of refractory vitiligo and developing targeted treatments are essential to enhance vitiligo outcomes. In this review, we summarized recent treatment approaches and some potential methods for refractory vitiligo. Janus kinase inhibitors have shown efficacy in refractory vitiligo. A variety of surgical interventions and fractional carbon dioxide laser have been widely applied to combination therapies. Furthermore, melanocyte regeneration and activation therapies are potentially effective strategies. Patients with refractory vitiligo should be referred to psychological monitoring and interventions to reduce the potential pathogenic effects of chronic stress. Finally, methods for depigmentation and camouflage may be beneficial in achieving uniform skin color and improved quality of life. Our ultimate focus is to provide alternative options for refractory vitiligo and to bring inspiration to future research.

Abstract
Vitiligo is a complex disease with a multifactorial nature and a high impact on the quality of life of patients. Although there are multiple therapeutic alternatives, there is currently no fully effective treatment for this disease. In the current era, multiple drugs are being developed for the treatment of autoimmune diseases. This review assesses the available evidence on the pathogenesis of vitiligo, and a comprehensive review of treatments available for vitiligo now and in the near future is provided. This qualitative analysis spans 116 articles. We reviewed the mechanism of action, efficacy and safety data of phototherapy, afamelanotide, cyclosporine, phosphodiesterase 4 inhibitors, trichloroacetic acid, basic fibroblast growth factor, tumor necrosis factor (TNF) inhibitors, secukinumab, pseudocatalase and janus kinase (JAK) inhibitors. At the moment, there is no clearly outstanding option or fully satisfactory treatment for vitiligo, so it is necessary to keep up the development of new drugs as well as the publication of long-term effectiveness and safety data for existing treatments.

Abstract
Vitiligo is an acquired chronic pigmentary disorder affecting the melanocytes, mainly in the skin and mucosae. It occurs due to the dynamic interaction between genetic and environmental factors leading to autoimmune destruction of melanocytes. Defects in melanocyte adhesion and increased oxidative stress further augment the immune response in vitiligo. It is a cosmetically disfiguring condition with a substantial psychological burden. Its autoimmune nature with resultant chronicity, variable responses to therapeutic modalities, and frequent recurrences have further diminished the quality of life. Hence, treatment should aim to provide more extended remission periods, prevent recurrences, provide good cosmetic outcomes and ensure patient satisfaction. These treatment goals seem plausible with the recent progress in our understanding of the complex pathogenic mechanisms underlying vitiligo at a molecular and genetic level. We provide a literature review of the pathogenic mechanisms and the therapies targeting these mechanisms.

Abstract
Importance Surgical interventions are a key part of the therapeutic arsenal, especially in refractory and stable vitiligo. Comparison of treatment outcomes between the different surgical procedures and their respective adverse effects has not been adequately studied. Objective To investigate the reported treatment response following different surgical modalities in patients with vitiligo. Data Sources A comprehensive search of the MEDLINE, Embase, Web of Science, and Cochrane Library databases from the date of database inception to April 18, 2020, was conducted. The key search terms used were vitiligo, surgery, autologous, transplantation, punch, suction blister, and graft. Study Selection Of 1365 studies initially identified, the full texts of 358 articles were assessed for eligibility. A total of 117 studies were identified in which punch grafting (n = 19), thin skin grafting (n = 10), suction blister grafting (n = 29), noncultured epidermal cell suspension (n = 45), follicular cell suspension (n = 9), and cultured epidermal cell suspension (n = 17) were used. Data Extraction and Synthesis Three reviewers independently extracted data on study design, patients, intervention characteristics, and outcomes. Random effects meta-analyses using generic inverse-variance weighting were performed. Main Outcomes and Measures The primary outcomes were the rates of greater than 90%, 75%, and 50% repigmentation response. These rates were calculated by dividing the number of participants in an individual study who showed the corresponding repigmentation by the total number of participants who completed the study. The secondary outcomes were the factors associated with treatment response to the surgical intervention. Results Among the 117 unique studies and 8776 unique patients included in the analysis, rate of repigmentation of greater than 90% for surgical interventions was 52.69% (95% CI, 46.87%-58.50%) and 45.76% (95% CI, 30.67%-60.85%) for punch grafting, 72.08% (95% CI, 54.26%-89.89%) for thin skin grafting, 61.68% (95% CI, 47.44%-75.92%) for suction blister grafting, 47.51% (95% CI, 37.00%-58.03%) for noncultured epidermal cell suspension, 36.24% (95% CI, 18.92%-53.57%) for noncultured follicular cell suspension, and 56.82% (95% CI, 48.93%-64.71%) for cultured epidermal cell suspension. The rate of repigmentation of greater than 50% after any surgical intervention was 81.01% (95% CI, 78.18%-83.84%). In meta-regression analyses, the treatment response was associated with patient age (estimated slope, -1.1418), subtype of vitiligo (estimated slope, 0.3047), and anatomical sites (estimated slope, -0.4050). Conclusions and Relevance The findings of this systematic review and meta-analysis suggest that surgical intervention can be an effective option for refractory stable vitiligo. An appropriate procedure should be recommended based on patient age, site and size of the lesion, and costs.

Abstract
Oral dexamethasone mini pulse (OMP) is an established treatment modality for active vitiligo. Cyclosporine may have therapeutic role in active vitiligo but current evidence supporting its role is scarce. The objective of study was to compare the efficacy and safety of oral cyclosporine with OMP in patients of active vitiligo. Fifty patients with active vitiligo were randomized into two groups of 25 patients. Group 1 was treated with OMP (2.5 mg dexamethasone) on two consecutive days/week for 4 months while group 2 was treated with cyclosporine (3 mg/kg/day) for 4 months. Laboratory monitoring was performed as per the prevalent protocol. The patients were followed up for another 2 months after stopping treatment. Arrest of disease progression (ADP) was defined as change of vitiligo disease activity score from 4+ to 3+ (time elapsed since last disease activity being more than 6 weeks upto 3 months) during the study period (6 months). ADP was attained in 21 patients in group 1 and 22 patients in group 2 (84% vs. 88%, p = 1.00) at the end of 6 months. However, mean time to achieve ADP was significantly lower in group 2 as compared to group 1 (10.92 [4.12] weeks vs. 13.90 [3.92] weeks, p = 0.01). Extent of repigmentation, improvement in patient assessment score, vitiligo quality of life and clinical markers of disease activity were marginal and comparable in both groups. Cyclosporine leads to earlier disease stabilization in active vitiligo as compared to OMP. Although considered a rescue drug in dermatology, low dose cyclosporine can be an effective therapeutic alternative in vitiligo patients.

Abstract
Network pharmacology is an emerging discipline that designs drugs based on systems biology theory and biological system network analysis. Here, we applied network pharmacology to analyze the multi-target mechanism of Cyclosporin A in the treatment of vitiligo First, we predicted the targets of Cyclosporin A. Second, we obtained the genes related to vitiligo from the database. Third, we constructed the PPI network of the mutual genes between Cyclosporin A and vitiligo and used gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) to analyze. Finally, we verified the prediction of potential targets through a docking study with Cyclosporin A. We found that there were 15 shared target genes between Cyclosporin A and vitiligo. We analyzed these 15 genes by Cytoscape and obtained a network diagram of 885 nodes. Through screening and molecular docking, PRKDC, CUL7, CUL1, HSPA8, HSPA4, and SIRT7 were the most likely multi-target mechanism of Cyclosporin A in the treatment of vitiligo. In our study, Cyclosporin A might not only affect the repair of DNA strands by targeting PRKDC, but also affected the innate and adaptive immune function of vitiligo patients by the targets of CUL1, CUL7, and HSP70. In addition, Cyclosporin A might promote the repigmentation of vitiligo by adjusting the expression of SIRT7.

Abstract
Vitiligo is a multifactorial disease characterized by the loss of skin pigment, which results in achromic macules and patches. There are currently several medical treatments available, which aim to arrest progression and induce skin repigmentation. These treatments alone or combined have exhibited varying degrees of pigmentation, and the majority are safe and effective. All therapies for vitiligo are limited, and no known treatment can consistently produce repigmentation in all patients. Individualized treatment is appropriate according to the location, clinical presentation and the presence of disease activity. The present review summarizes the medical treatments available for vitiligo: Systemic and topic pharmacological therapies, physical and depigmentation treatments. Several treatments are still underway and have not yet been approved. However, due to the promising preliminary results, these are also mentioned in the present review.

Abstract
This is an exciting phase of vitiligo research with the current understanding of vitiligo pathogenesis and its translation to successful treatment. The pathogenetic origin of vitiligo revolves around autoimmunity with supporting role from many other factors like oxidative stress, inherent melanocyte defects, or defective keratinocytes and fibroblasts. Vitiligo can be classified into segmental or non-segmental depending upon the clinical presentation, or it can be classified as progressing or stable based on the activity of the disease. Vitiligo treatments need to be stratified depending upon which type of vitiligo we are treating and at which phase the vitiligo patient presents to us. There are two different aims of treatment of vitiligo. The first involves rescuing the melanocytes from the damage to arrest the depigmentation. The second strategy focuses on replenishing the melanocytes so that successful repigmentation is achieved. It is also important to maintain the disease in a stable phase or prevent relapse. As stability in non-segmental vitiligo is a dynamic process, maintenance of the stability of repigmentation is also an important consideration in the management of vitiligo. In this review, we shall briefly discuss the current options and future insight into the management of vitiligo.

Abstract
Stabilized vitiligo resistant to conventional therapy (e.g. segmental vitiligo) and piebaldism lesions can be treated with autologous cellular grafting techniques, such as non-cultured cell suspension transplantation (NCST) and cultured melanocyte transplantation (CMT). These methods are preferred when treating larger surface areas due to the small amount of donor skin needed. However, the donor to recipient expansion ratios and outcomes reported in studies with cellular grafting vary widely, and to date, no overview or guideline exists on the optimal ratio. The aim of our study was to obtain an overview of the various expansion ratios used in cellular grafting and to identify whether expansion ratios affect repigmentation and colour match. We performed a systematic literature search in MEDLINE and EMBASE to review clinical studies that reported the expansion ratio and repigmentation after cellular grafting. We included 31 eligible clinical studies with 1591 patients in total. Our study provides an overview of various expansion ratios used in cellular grafting for vitiligo and piebaldism, which varied from 1:1 up to 1:100. We found expansion ratios between 1:1 and 1:10 for studies investigating NCST and from 1:20 to 1:100 in studies evaluating CMT. Pooled analyses of studies with the same expansion ratio and repigmentation thresholds showed that when using the lowest (1:3) expansion ratio, the proportion of lesions achieving >50% or >75% repigmentation after NCST was significantly better than when using the highest (1:10) expansion ratio (χ2 P = 0.000 and χ2 P = 0.006, respectively). Less than half of our included studies stated the colour match between different expansion ratios, and results were variable. In conclusion, the results of our study indicate that higher expansion ratios lead to lower repigmentation percentages after NCST treatment. This should be taken into consideration while determining which expansion ratio to use for treating a patient.

Abstract
Background: Autologous non-cultured melanocyte-keratinocyte transplantation (MKTP) can be used to treat stable vitiligo cases, but there were insufficient clinical data to evaluate its safety and efficacy. Objective: To assess the influence of various factors on the therapeutic outcome of MKTP. Method: The single-center retrospective study included stable vitiligo patients who underwent MKTP between June 2009 and June 2018. Univariate and/or multivariable analysis were used to determine the factors affecting the outcome of repigmentation. Result: The study comprised 2283 patients who had long-term follow-up data (12-108months). Excellent repigmentation was achieved in 400/606 (66%),788/1341 (58.8%),437/684 (63.9%),18/24 (75%) patients with segmental vitiligo, pre-MKTP phototherapy, younger than 24 years, the lesion on the perineum and scrotum, respectively. However, the patients with a positive family history, Koebner phenomenon responded worse(χ2=29.417, P<0.001; χ2=107.397, P<0.001; respectively). Overall, a significant positive correlation between duration of stability and percentage of repigmentation was found (χ2=42.053, P<0. 001). Conclusion: MKTP is efficient and well tolerated for stable vitiligo treatment. Various factors such as duration of disease stability, vitiligo type, family history, site of lesion should be carefully assessed before using MKTP, as it would further improve the post-operative repigmentation.

Abstract
Vitiligo is an autoimmune skin condition characterized by depigmented macules and patches, and has a huge psychosocial impact on patients. Treatment of vitiligo aims to prevent the spread of disease and facilitate repigmentation of affected lesions. The mainstay of treatment for unstable vitiligo has been topical agents (corticosteroids, calcineurin inhibitors) and phototherapy. However, systemic treatments are increasingly being shown to have a significant impact on the course of the disease as monotherapy or adjunctive therapy. Of note, oral mini-pulsed corticosteroid therapy, methotrexate, minocycline, ciclosporin, Janus kinase inhibitors and certain supplements have been used in the systemic treatment of vitiligo. We review the underlying evidence supporting the use of each of these systemic treatments.

Abstract
BACKGROUND Melanocyte-keratinocyte transplantation procedure (MKTP) is an effective surgical technique for restoring skin pigmentation in all types of vitiligo and leukoderma patients who are unresponsive to medical and/or phototherapy treatment. Data specific to the outcomes of MKTP among Thai vitiligo and nevus depigmentosus patients are currently scarce. OBJECTIVES To evaluate the efficacy and safety of MKTP in patients with vitiligo or nevus depigmentosus at the short-term (≤6 months) and long-term (≥12 months) follow-up. MATERIALS AND METHODS A retrospective review of the medical records of vitiligo or nevus depigmentosus patients who underwent MKTP at the Department of Dermatology, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand during 2016 to 2019 was conducted. Repigmentation outcomes were evaluated by Vitiligo Area Scoring Index (VASI). RESULTS Twenty-five patients had 27 MKTP surgeries on 32 anatomically-based lesions. The mean age was 32.4 years, the mean age at onset was 25.5 years, and 19 patients were male. Segmental vitiligo, non-segmental vitiligo, and nevus depigmentosus had significantly improved VASI scores at the short-term follow-up (-74.2% ± 23.2%, -100%, and -62.5% ± 17.6%, respectively) and the long-term follow-up (-81% ± 27.7%, -95.0% ± 7.0%, and -83.3% ± 14.4%, respectively). CONCLUSION MKTP is a safe and effective method for treating refractory vitiligo and nevus depigmentosus in Thai patients.

Int J Dermatol 2018; 57:770-775. [PMID: 29318598 DOI: 10.1111/ijd.13895] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2017] [Revised: 10/31/2017] [Accepted: 12/03/2017] [Indexed: 11/28/2022]
Abstract
Vitiligo is an acquired pigmentary skin of depigmentation occurring secondary to melanocyte destruction. Vitiligo and other leukodermas have a profound impact on quality of life. Current therapies include medical options, such as phototherapy, topical and systemic corticosteroids, topical calcineurin inhibitors, immunomodulators, and antioxidiants, and surgical options. Surgical options provide melanocytic cells to previously depigmented areas and use either tissue grafting or cellular grafting methods. Topical treatments are often insufficient, and many of the current surgical procedures have shown variable response rates. In this review, we discuss the process of the cellular grafting melanocyte-keratinocyte transplantation procedure (MKTP) and critically analyze its efficacy and safety in the treatment of vitiligo and other leukodermas. PubMed was searched for studies (2001-2017) describing the use of MKTP in patients with vitiligo or other leukodermas. Articles or trials discussing the use of MKTP for these patients were selected for in-depth review. Clinically relevant results regarding efficacy and safety of MKTP in vitiligo and leukoderma patients were analyzed. Numerous trials and case series/reports have demonstrated tolerability and efficacy of MKTP with repigmentation for patients with refractory, stable vitiligo. However, the response rates have been variable, likely influenced by vitiligo type and affected areas. Future research and clinical reporting will provide more insight on which phenotypes may benefit from MKTP.
