Abstract
INTRODUCTION Vitiligo, a chronic autoimmune skin depigmentation disease with an unpredictable course, has been associated with several comorbid autoimmune and psychological conditions. Our current understanding of vitiligo burden and management in the real world is limited. This real-world analysis presents data on vitiligo epidemiology, comorbidities, and treatment of patients in Israel. METHODS This retrospective study analyzed data from the Maccabi Health Services database. Prevalent patients with vitiligo in 2021 were matched to patients in the general population on the basis of age group, gender, and socioeconomic status. Patient demographics, vitiligo incidence and prevalence, comorbidities, and treatment patterns are reported. Data are presented as percentages, mean, median, P values, and standard mean differences (SMD). RESULTS In this analysis, 11,412 patients with vitiligo were matched to patients from the general population. Incidence and prevalence rates increased over time from 2005 to 2021. Compared to the general population, patients with vitiligo were more likely to have an immune-mediated comorbidity (29.7% vs 18.4% [P < 0.001; SMD 0.27]) or psychological comorbidity (18.7% vs 15.9% [P < 0.001; SMD 0.07]). Comorbidities included atopic dermatitis (patients with vitiligo vs general population 12.5% vs 8.4%), psoriasis (5.8% vs 3.6%), Hashimoto's thyroiditis (2.9% vs 1.1%), alopecia areata (2.2% vs 0.9%), depression (10.8% vs 9.5%), and sleep disorder/insomnia (5.9% vs 4.4%). Only 74.8% of all patients with vitiligo had ever received treatment, with topical corticosteroids (51.5%) and calcineurin inhibitors (36.5%) most commonly prescribed. At the end of 2021, 83.7% of patients were untreated. CONCLUSION Patients with vitiligo are more likely to have various immune-related and psychological comorbidities, highlighting the significant impact of the condition on well-being. Nearly a quarter of patients had never received treatment, with many receiving only topical treatments, and medication persistence was low. This highlights the lack of adequate treatment in this population and the need for more effective management options.

Abstract
BACKGROUND CD20+ T cells represent up to 5% of circulating T lymphocytes. These cells have been shown to produce higher levels of IL-17A and IFN-γ than those of CD20- T lymphocytes. Some reports described the role of CD20+ T cells in autoimmune disorders such as multiple sclerosis and rheumatoid arthritis possibly due to their ability to produce these inflammatory cytokines. This study is aimed at describing the behavior of CD20+ T lymphocytes in the most frequent autoimmune disorder, i.e., Hashimoto's thyroiditis (HT), presenting isolated or associated to further autoaggressive disorders in a frame of poly-autoimmunity. METHODS The study group encompasses 65 HT patients: 23 presenting in isolated form (IT) and 42 with an associated non-endocrine autoimmune disorder [16 with chronic atrophic gastritis (CAG), 15 with nonsegmental vitiligo (VIT), and 11 with celiac disease (CD)]. Twenty healthy donors act as control group (HD). Chronic use of interfering drugs, severe or chronic disorders, and pregnancy and lactation were used as exclusion criteria. Whole blood samples (100 µl) were stained with fluorescent-labeled antibodies (anti-CD45, anti-CD3, anti-CD19, anti-CD16, anti-CD56, anti-CD4, anti-CD8, anti-CD20). Red blood cells were then lysed by adding 1 ml of hypotonic buffer, and samples were acquired on a Flow Cytometer. RESULTS CD3+CD8+CD20+ T lymphocytes' percentages, were significantly higher in the whole group of autoimmune patients compared to healthy donors (p = 0.0145). Dividing HT patients based on the type of presentation of autoimmune thyroiditis, CAG group showed the highest percentage of these cells as compared to HD and CD (p = 0.0058). IT patients showed higher percentages of CD3+ CD8+CD20+ cells than those of HD patients although not reaching statistical significance. However, dividing IT group based on thyroid function, hypothyroid patients showed higher CD8+CD20+ cell percentages than those of HD and euthyroid patients (p = 0.0111). Moreover, in IT patients, these cells were negatively correlated with FT4 levels (p = 0.0171; r = -0.4921). CONCLUSIONS These preliminary findings indicate that CD8+CD20+ T cells are activated in patients with autoimmune thyroiditis and may behave differently according to the presence of poly-autoimmunity and hypothyroidism.

Abstract
Importance Evidence-based recommendations for the treatment of vitiligo in pediatric, adolescent, and young adult patients in the US are needed. Objective To develop evidence- and consensus-based expert recommendations on the diagnosis and treatment of vitiligo in young patients. Evidence Review A process was developed to produce consensus recommendations addressing questions regarding pediatric vitiligo. A librarian-conducted literature review was performed using articles that met the inclusion criteria: published in English, containing primary data (including meta-analysis) and pediatric-specific data, and analysis of 6 or more patients. Included articles were graded by the Strength of Recommendation Taxonomy criteria and Oxford Centre for Evidence-based Medicine's Levels of Evidence and Grades of Recommendation. Research questions were reviewed on May 9, 2022, through a video conference. One month after the conference, participants participated in an online survey documenting their level of agreement with the generated statements, using a 5-point Likert scale. Findings Articles on topical corticosteroids and/or topical calcineurin inhibitors (n = 50), topical Janus kinase inhibitors (n = 5), pseudocatalase (n = 2), and microdermabrasion (n = 2) met inclusion criteria. Forty-two recommendations were made on the diagnosis of vitiligo and optimal topical therapeutics, with 33 recommendations obtaining a 70% or greater composite agreement and strong agreement. Topical calcineurin inhibitors twice daily, topical corticosteroids with time limitation due to atrophy risk, and topical ruxolitinib, 1.5%, cream-used off-label for patients younger than 12 years and limited to nonsegmental vitiligo-were identified as evidence-based first-line therapies in the management of pediatric and adolescent patients, with specific guidance on age-based data, minimum therapeutic trial of 6 months or greater, prolonged therapy to prevent recurrence, and the positive benefit of coordinated use of UV therapeutic sources. Conclusions and Relevance Evidence supports the use of topical calcineurin inhibitors, topical corticosteroids, and topical Janus kinase inhibitors as effective therapeutics for vitiligo in pediatric, adolescent, and young adult patients, with specific decisions on choice of agent based on factors such as site location, body surface area, and age.

Abstract
Narrowband ultraviolet-B (NB-UVB) phototherapy is the mainstay of vitiligo therapy. The response can be evaluated using the vitiligo area scoring index (VASI) and repigmentation grade. However, few studies used VASI to evaluate phototherapy response and there are no definitive data on the reduction of VASI. This retrospective descriptive study aimed to determine the characteristics and decrease of VASI in patients with vitiligo after 36 and 48 sessions of NB-UVB phototherapy, conducted at Dr. Sardjito General Hospital, Yogyakarta, from December 2021-June 2022. The most common predilection was on the face (71.43%) and acral (61.90%). The most common responses after 36 and 48 phototherapy sessions were minimally improved (decrease in VASI<10%) and improved (reduction in VASI 10-25%). The mean decrease in VASI was 18% and 22% after 36 and 48 phototherapy sessions, respectively. 9.52% and 6.67% of patients experienced a reduction in VASI >50% after 36 and 48 phototherapy sessions, respectively. VASI assessment can be used to evaluate the response to phototherapy in vitiligo. However, VASI cannot show a reduction in vitiligo with slight repigmentation in slow-response patients.

Abstract
Vitiligo is a chronic pigmentary condition and severely impacts patient quality of life (QoL). It is an underrecognized burden for patients, healthcare systems, and society in Latin America (LA). This paper examines the journey of a vitiligo patient in LA and assesses the disease landscape. Americas Health Foundation (AHF) assembled a panel of six Argentine, Brazilian, Colombian, and Mexican vitiligo experts. On 10-12 May 2022, they met in a virtual meeting. Each panelist wrote a short paper on barriers to vitiligo diagnosis and treatment in LA before the meeting. AHF staff moderated as the panel reviewed and modified each paper over three days. The panel approved the recommendations based on research, professional opinion, and personal experience. The panel agreed that lack of disease awareness and research, social ostracization, and limited therapeutic options hinder patients in their quest for diagnosis and treatment. In addition to the medical and psychological difficulties associated with vitiligo, problems connected to the Latin American healthcare system may negatively impact diagnosis, prognosis, and treatment. Access to timely diagnosis and treatment is crucial for improving outcomes. Governments, medical societies, academics, patient organizations, industry, and the public must unite to eliminate these challenges.

Abstract
BACKGROUND AND PURPOSE Treating vitiligo in clinical practice is challenging. Furthermore, oral drugs used in Western medicine have considerable side effects and are unsuitable for long-term treatment. In contrast, Chinese patent medicines (CPMs) are more suitable for long-term oral vitiligo treatment, but medical evidence of their efficacy and safety is lacking. Therefore, in this study, the efficacy and safety of CPMs were evaluated and ranked using a Bayesian network meta-analysis. METHODS Seven Chinese and English databases were searched for all relevant articles published up to February 2023. The Bayesian network meta-analysis method was used to analyze the extracted data to evaluate efficacy and safety. RESULTS Six common CPMs for treating vitiligo were selected in our study, and 48 targeted articles and 4446 patients were included. This study showed that Qubai Babuqi tablets (QT) were the most effective for short-term treatment of vitiligo, and that vitiligo capsules or pills (VCP) were the most effective for long-term treatment, together with compound Quchong Banjiuju pills (QP). In terms of surface area under the cumulative ranking curve (SUCRA) values, the order of efficacy of each treatment was as follows: QT (92.18%) > Taohong Qingxue pills (TP) (63.81%) > VCP (55.53%) > QP (50.72%) > Bailing tablets or capsules (BTC) (49.01%) > Baishi pills (BP) (35.69%)>routine therapy (RT) (3.1%) in terms of total effective rate and QT (92.05%) > VCP (71.50%) > QP (66.60%) > TP (42.95%) > BTC (39.66%) > BP (36.60%)>RT (0.6%) in terms of improvement rate. In addition, the safety of the 6 CPMs did not significantly differ in terms of adverse effects. The SUCRA values indicated that QT performed slightly worse than other drugs. DISCUSSION In treating vitiligo, QT is most effective but only suitable for short-term administration owing to its poor safety. VCP and QP could be used as first-choice long-term medications. TP may positively affect repigmentation in patients with limited lesion areas.

Abstract
Vitiligo is a disease caused by the acquired depletion of melanocytes and/or melanocyte precursor cells in response to genetic and environmental factors, resulting in depigmentation of the entire body. It is roughly divided into segmental and non-segmental vitiligo, and it has been found that abnormalities of melanocytes themselves and dysregulation of autoimmune responses to melanocytes are greatly involved in the pathology of non-segmental vitiligo. Segmental vitiligo pathology is largely unknown; however, it has been suggested that it may be caused by skin or melanocyte mosaicism. Treatments for vitiligo include topical therapy, ultraviolet therapy, and surgical transplantation, and it is extremely important to correctly understand the pathology to perform optimal treatment. In recent years, the development of vitiligo treatments using Janus kinase (JAK) inhibitors has progressed rapidly. We herein outline the latest pathology of vitiligo, from general vitiligo treatment to the progress of clinical trials using JAK inhibitors, along with what clinicians should consider in archiving precision medicine, including my own ideas thereon.

Abstract
The epidemiology of vitiligo, especially its disease burden on the healthcare system, can be assessed indirectly by analyzing health insurance claims data. Validating this approach is integral to ensuring accurate case identification and cohort characterization. The primary aim of this study was to develop and validate an indirect measure of vitiligo ascertainment using health insurance claims data. These data were used secondarily to identify demographic characteristics, body site involvement, vitiligo subtypes, disease associations, and treatments. This study assessed the validity of identifying vitiligo from billing claims within a Canadian provincial universal health insurance program, versus vitiligo cases accrued from direct medical chart reviews. Claims-based algorithms combining ICD-9-CM diagnostic code 709 with treatment-specific data were derived and tested to identify vitiligo patients. This was compared against cases arising from the manual review of medical records of 606 patient with a diagnostic code for "dyschromia" (ICD-9-CM diagnostic code 709) from January 1 to December 31, 2016. Based on the chart reviews, 204 (33.7%) patients were confirmed to have vitiligo. 42 separate claims-based algorithms combining ICD-9-CM diagnostic code 709 with treatment data specific to vitiligo were modeled and individually tested to evaluate their accuracy for vitiligo ascertainment. One algorithm achieved a sensitivity, specificity, PPV and NPV of 86.8% (95% CI 82.1-91.4), 92.5% (95% CI 90.0-95.1), 85.5% (95% CI 80.7-90.3), and 93.2% (95% CI 90.8-95.7), respectively. There was a 2.2 female-to-male ratio. The most common medical treatments were tacrolimus (74.5%) and topical corticosteroids (54.3%). Hypertension (24.2%) and hypothyroidism (19.6%) were the predominant co-morbidities associated with vitiligo. Health insurance claims data can be used to indirectly ascertain vitiligo for epidemiologic purposes with relatively high diagnostic performance between 85.5 and 93.2%.

Abstract
Vitiligo is a chronic autoimmune disease characterized by loss of pigment of the skin, affecting 0.5-2% of the population worldwide. It can have a significant impact on patients' quality of life. In recent years, there has been significant progress in our understanding of the pathogenesis of vitiligo. It is believed that vitiligo develops due to a complex combination of genetics, oxidative stress, inflammation, and environmental triggers. Conventional treatments include camouflage, topical corticosteroids, topical calcineurin inhibitors, oral corticosteroids, phototherapy, and surgical procedures, with the treatment regimen dependent on the patient's preferences and characteristics. With increased understanding of the importance of the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway in the pathogenesis of vitiligo, treatment has expanded to include the first US FDA-approved cream to repigment patients with vitiligo. This review summarizes our understanding of the major mechanisms involved in the pathogenesis of vitiligo and its most common available treatments.

Abstract
Vitiligo is an autoimmune skin disorder resulting in the depigmentation of skin characterised by patches of varying sizes and shapes. A common disorder of pigmentation that affects 0.5%-2% of the global population. Despite its well-understood autoimmune pathogenesis, the targets for effective cytokine intervention remain unclear. Current first-line treatments include oral or topical corticosteroids, calcineurin inhibitors and phototherapy. These treatments are limited, have varying efficacies, and are associated with significant adverse events or can be time-consuming. Therefore, biologics should be explored as a potential treatment for vitiligo. There are currently limited data for the use of JAK and IL-23 inhibitors for vitiligo. A total of 25 studies were identified in the review. There is promising evidence regarding the use of JAK and IL-23 inhibitors for the treatment of vitiligo.

Abstract
Extracellular tissue fluids are interesting biomatrices that have recently attracted scientists' interest. Many significant biomarkers for localized external organ diseases have been isolated from this biofluid. In the diagnostic and disease monitoring context, measuring biochemical entities from the fluids surrounding the diseased tissues may give more important clinical value than measuring them at a systemic level. Despite all these facts, pushing tissue fluid-based diagnosis and monitoring forward to clinical settings faces one major problem: its accessibility. Most extracellular tissue fluid, such as interstitial fluid (ISF), is abundant but hard to collect, and the currently available technologies are invasive and expensive. This is where novel microneedle technology can help tackle this significant obstacle. The ability of microneedle technology to minimally invasively access tissue fluid-containing biomarkers will enable ISF and other tissue fluid utilization in the clinical diagnosis and monitoring of localized diseases. This review attempts to present the current pursuit of the application of microneedle systems as a diagnostic and monitoring platform, along with the recent progress of biomarker detection in diagnosing and monitoring localized external organ diseases.

Hu W, Lin F, Lei J, Xu AE. Impacts of exposure to topical calcineurin inhibitors on metabolism in vitiligo infants. Pediatr Res 2023; 93:661-665. [PMID: 35681095 DOI: 10.1038/s41390-022-02133-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2021] [Revised: 05/11/2022] [Accepted: 05/17/2022] [Indexed: 11/09/2022]
Abstract
BACKGROUND Tacrolimus ointment is a recently developed topical immunomodulator that has been approved for use in patients with vitiligo older than 2 years. Concern regarding potential systemic toxic effects has limited treatment options for children younger than 2 years. We wanted to determine whether topical tacrolimus therapy is safe and effective in patients with vitiligo younger than 2 years. METHODS The present 6-month clinical trial was conducted to evaluate the efficacy and safety of 0.03% tacrolimus in the treatment of vitiligo in children under 2 years of age. Meanwhile, serum and urine samples were collected, and liquid chromatography-mass spectrometry was performed to generate the serum and urine metabolic profile data of patients and healthy controls. RESULTS The overall response rate at the sixth month, which was defined by the degree of re-pigmentation, was 100%. As revealed by blood monitoring and metabolite detection 6 months later, there was no difference between the treatment group and the control group. There is no evidence that long-term topical application of 0.03% tacrolimus ointment will cause metabolite or other physical changes in the body. CONCLUSIONS Tacrolimus ointment appears to be effective and safe in the treatment of vitiligo in children younger than 2 year. TRIAL REGISTRATION http://www.chictr.org.cn identifier: ChiCTR 2100045920. IMPACT We first reported the efficacy and safety of topical application of 0.03% tacrolimus ointment in infants with vitiligo characterized by the metabolites. There is no evidence that long-term topical application of 0.03% tacrolimus ointment will cause metabolite or other physical changes in the body. This study provide evidence for the TCI treatment of infants with vitiligo.

Abstract
Objective To assess the frequency of polyautoimmunity (PolyA) in a cohort of Colombian patients with systemic lupus erythematosus (SLE) and to identify associated factors. Methods This is an analytical cross-sectional study in a specialized center., a comprehensive review of the medical records of SLE patients was performed from 2015 to 2020 in order to obtain demographic, clinical data, laboratory, and treatment information. Associations between PolyA, demographic, and characteristics of the disease were explored. Results A total of 463 patients were included in the analysis. The average age was 47.3 ± 15 years. Most of this population were female (87.4%), whom were diagnosed with SLE in a long-term SLE (10.6 ± 10.1 years). Out of the total patients, 34.7% were diagnosed with PolyA. Among the most frequent clinical criteria for SLICC, arthritis (65%), kidney impairment (39.5%), and alopecia (34.8%) were found. The most frequent SLE-associated PolyA were antiphospholipid syndrome (APS) and Sjögren's syndrome (SS) (16.63% and 10.58%, respectively). PolyA-associated factors were age, xerophthalmia, central nervous system occlusion, and deep vein thrombosis (DVT). In contrast, renal impairment was significantly less frequent in PolyA patients after multivariate analysis. Conclusion The results have showed associated factors with PolyA like age, xerophthalmia, central nervous system occlusion, and deep vein thrombosis in this cohort. On the other hand, lupus nephritis was less frequent in patients with PolyA. This study provides a spotlight of a specific SLE population as real-life evidence for a better characterization of PolyA in the future.

Abstract
Vitiligo is a common depigmentation disorder of an unknown origin characterized by the selective loss of melanocytes, resulting in typical white macules and patches. However, vitiligo is now recognized as more than just a skin disease, what a dermatologist observes as a white spot of skin is just the "tip of the iceberg" of the condition. We attempt to clarify the classification of comorbidities associated with vitiligo from various reviews and reports, and describe their possible pathogenesis. In conclusion, the literature provides evidence of an association between vitiligo and ocular and auditory abnormalities, autoimmune disorders, other dermatological diseases, metabolic syndrome and related disorders, and psychological diseases. These associations highlight the importance of a multidisciplinary approach in managing vitiligo patients.

Abstract
Background A large number of autologous melanocytes are required for surgical treatment of depigmentation diseases such as vitiligo. The purpose of this experiment is to explore the application of melanocytes induced by mesenchymal stem cells to clinical treatment. Therefore, we have induced mouse bone marrow mesenchymal stem cells (BMMSCs) into melanocytes (miMels) in the previous experiment. This experiment continues the previous experiment to further study the biological functions of miMels and their application in tissue engineering. Methods We examined whether miMels can produce active tyrosinase, melanin, and response to α-MSH. The ability of miMels to produce melanin to keratinocytes was tested by co-culture. By applying miMels to tissue-engineered skin, the survival and function of miMels on the surface of nude mice were verified. Results MiMels can produce active tyrosinase and melanin, and can pass melanin to the co-cultured keratinocytes. Under the stimulation of α-MSH, the active tyrosinase and melanin content of miMels increased. We tried to apply it to the establishment of tissue-engineered skin and obtained tissue-engineered skin containing miMels. Then we tried to transplant tissue-engineered skin on the back skin of nude mice and succeeded. The transplanted miMels survived in local tissues, synthesized active tyrosinase and melanin, and expressed the marker protein of melanocytes. Conclusion In short, miMels can be used as a cell source for tissue engineering skin. MiMels not only have a typical melanocyte morphology but also have the same biological functions as normal melanocytes. What's more important is its successful application in mouse tissue-engineered experiments.

Abstract
Skin, the largest organ of the body, plays a vital role in protecting inner organs. Skin stem cells (SSCs) comprise a group of cells responsible for multiplication and replacement of damaged and non-functional skin cells; thereby help maintain homeostasis of skin functions. SSCs and differentiated cells of the skin such as melanocytes and keratinocytes, have a plethora of applications in regenerative medicine. However, as SSCs reside in small populations in specific niches in the skin, use of external stimulants for cell proliferation in vitro and in vivo is vital. Synthetic and recombinant stimulants though available, pose many challenges due to their exorbitant prices, toxicity issues and side effects. Alternatively, time tested traditional medicine preparations such as polyherbal formulations are widely tested as effective natural stimulants, to mainly stimulate proliferation, and melanogenesis/prevention of melanogenesis of both SSCs and cells of skin origin. Complex, multiple targets, synergistic bioactivities of the phytochemical constituents of herbal preparations amply justify these as natural stimulants. The use of these formulations in clinical applications such as in skin regeneration for burn wounds, wound healing acceleration, enhancement or decrease of melanin pigmentations will be in great demand. Although much multidisciplinary research is being conducted on the use of herbal formulas as stem cell stimulants, very few related clinical trials are yet registered with the NIH clinical trial registry. Therefore, identification/ discovery, in depth investigations culminating in clinical trials, as well as standardization and commercialization of such natural stimulants must be promoted, ensuring the sustainable use of medicinal plants.

Abstract
Oxidative stress is one of the triggering factors for vitiligo, which leads to melanocyte (MC) destruction in vitiligo lesions. Ferroptosis, which is characterized by iron-dependent increase in oxidative stress and lipid peroxidation, has been widely explored in numerous diseases, whereas whether ferroptosis plays a role in MC loss of vitiligo remains to be elucidated. Quantitative real-time PCR and western blot analysis were used to determine the expression of ferroptosis markers in vitiligo patients. Immunonephelometry and electrochemiluminescence were performed to analyze iron status. Reactive oxygen species (ROS), Fe2+ , and lipid ROS were assessed by flow cytometry. The expression of ferroptosis markers was significantly altered in the epidermis of vitiligo patients. Iron deficiency was revealed in the blood of patients. Erastin reduced cell viability and led to oxidative stress, iron overload as well as lipid peroxide accumulation in human epidermal MCs in vitro. Altered expression of ferroptosis markers and inhibition of melanin synthesis in MCs were induced by erastin, which was attenuated by N-acetyl-L-cysteine (NAC) pretreatment or post-treatment in vitro. In conclusion, ferroptosis might take place during the process of vitiligo. Erastin could induce ferroptosis in human epidermal MCs and NAC could protect MCs from ferroptosis in vitro.

Abstract
Aim: Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare, highly variable disease with significant oral health impacts. The aim of the study is to examine the existing evidence base surrounding the oral health impacts of APECED and consider the wider clinical significance of the condition relevant to the provision of pediatric dental care. Materials and Methods: The evidence surrounding APECED and the oral health impacts obtained from a review of multiple databases was qualitatively summarized in the form of a literature review. A case study was used to illustrate the relevance of literature in caring patients with APECED. Results: The literature describes a broad range of impacts from APECED, although it is characterized by chronic candidal infection, autoimmune hypoparathyroidism, and Addison’s disease. Oral manifestations of APECED appear frequently and can present early. Developmental defects of the teeth affect a large proportion of patients with APECED and together with candidiasis, characterize the key oral manifestations of the disease. An enhanced preventive and minimally invasive approach to oral health care is recommended for these patients in light of the complexities of their medical condition. Conclusion: Patients with APECED require careful multidisciplinary care to ensure that the optimal oral health outcomes are achieved.

Abstract
Little is known about the use of antioxidants in the clinical treatment of vitiligo. To investigate the specific use of antioxidants in the treatment of vitiligo and the possible reasons behind its use in China, we conducted a prospective questionnaire-based study using an online questionnaire comprising 26 questions in 5 areas. A total of 323 clinical frontline dermatologists participated in this study. Differences among groups were compared using Pearson’s chi-square test. Ordinal logistic regression was used to develop knowledge–use multiple regression models. Among the 323 dermatologists, 293 (90.7%) approved the oxidative stress theory of vitiligo, and 182 (56.3%) encouraged the use of antioxidants for treating vitiligo; nonetheless, only 11.8% frequently treated vitiligo with antioxidants. Insufficient knowledge of antioxidants was a significant predictor of lower frequency of antioxidant usage (adjusted odds ratio, 0.401 [95% confidence interval, 0.256-0.629];
). The predictors associated with higher antioxidant efficacy included advanced or rapid progression, moderate or moderate-to-severe vitiligo, age of 0–2 years or 13–18 years, segmental vitiligo, oral and topical combination therapy, and course duration of <1 month. The use of antioxidants for treating vitiligo is highly encouraged; however, the rates of their clinical use are considerably low. Insufficient knowledge of antioxidants is associated with a lower frequency of antioxidant usage. The synergistic curative efficacy of antioxidants could be affected by the stage, type, severity, age of patients with vitiligo, and method of using antioxidants.

Abstract
Regulatory T cells are critical for maintaining immune tolerance. Recent studies have confirmed their therapeutic suppressive potential to modulate immune responses in organ transplant and autoimmune diseases. However, the unknown and nonspecific antigen recognition of polyclonal Tregs has impaired their therapeutic potency in initial clinical findings. To address this limitation, antigen specificity can be conferred to Tregs by engineering the expression of transgenic T-cell receptor (TCR) or chimeric antigen receptor (CAR). In contrast to TCR Tregs, CAR Tregs are major histocompatibility complex (MHC) independent and less dependent on interleukin-2 (IL-2). Furthermore, CAR Tregs maintain Treg phenotype and function, home to the target tissue and show enhanced suppressive efficacy compared to polyclonal Tregs. Additional development of engineered CAR Tregs is needed to increase Tregs’ suppressive function and stability, prevent CAR Treg exhaustion, and assess their safety profile. Further understanding of Tregs therapeutic potential will be necessary before moving to broader clinical applications. Here, we summarize recent studies utilizing CAR Tregs in modulating immune responses in autoimmune diseases, transplantation, and gene therapy and future clinical applications.

Dermatol Res Pract 2021; 2021:5652140. [PMID: 34887918 PMCID: PMC8651420 DOI: 10.1155/2021/5652140] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2021] [Revised: 11/02/2021] [Accepted: 11/12/2021] [Indexed: 11/17/2022] Open
Abstract
Objective Vitiligo is a common, autoimmune disease that results in the destruction of the melanocytes and manifests as depigmented macules on various areas of the skin. Numerous treatment options have been proposed for vitiligo. The purpose of this study was to compare the efficacy of microneedling plus topical pimecrolimus 1% versus the sole use of topical pimecrolimus 1% for the treatment of vitiligo. Methods This clinical trial was conducted on 30 skin lesions on 15 Al-Zahra hospital patients. Each patient had two similar lesions in the limb area, and each lesion was considered a separate treatment group. The left or right side of the patient's lesion was randomly assigned to receive microneedling plus topical pimecrolimus for three months, while the other side received only topical pimecrolimus 1%. As part of the follow-up, digital photography was taken at the baseline and biweekly for three months after treatment and six months' follow-up. The following methods were used to evaluate the results: DLQI questionnaires, patient satisfaction questionnaires, and two independent dermatologists comparing the improvement rate for each group. Results Topical pimecrolimus 1% treatment led to unsatisfactory results, whereas the combination of microneedling and topical pimecrolimus1% treatment produced a more favorable overall outcome (P < 0.001). Conclusion This study established that combination therapy results in more significant patient improvement. Additionally, one patient experienced mild skin irritation as a side effect of topical pimecrolimus.

Abstract
In spite of multiple therapeutic regimens for vitiligo, disease relapse remains a challenge. Most guidelines consider systemic treatments only in rapidly progressive disease with wider surface areas. This delay in halting the immune attack, may give the chance for further disease progression as well as establishment of resident memory T-cell population predisposing to future relapses. To assess the ability of early systemic therapy of localized (<2% BSA), recent onset (<6 months) vitiligo to control disease activity and minimize the possibility of recurrence. Twenty-five patients with recent onset (<6 months), localized (<2% BSA) vitiligo were included. Patients received pulse dexamethasone therapy for 6 months plus topical treatments and NB-UVB sessions. Patients were followed monthly as regards percent of repigmentation and VIDA score. To detect recurrence, biannual assessment was done for 4 years. Eighty-four percent of patients had acrofacial lesions and 44% had facial lesions. Arrest of activity was achieved after 3.65 ± 2.19 months. Complete repigmentation was achieved in a mean duration of 6.88 ± 0.2 months. At the end of the 4-year follow up, recurrence occurred in 32% of patients. In spite of recurrence, localized disease (<2% BSA) was secured. A significantly higher incidence of recurrence was associated with cases with bilateral distribution of lesions. Early systemic immunomodulation for recent localized vitiligo is a successful approach to achieve early control of disease activity and minimize the incidence of recurrence. Such cases should not be overlooked but managed as early as possible; it is a race against time.

Abstract
Extremely limited drug retention and depigmentation represent the greatest barriers against vitiligo treatment advancement. Here, inspired by biological melanosomes, the primary melanin transporter, we developed biomimetic melanosomes to combat reactive oxygen species (ROS)-mediated melanocyte damage and depigmentation. Briefly, methylprednisolone (MPS) and melanin-mimicking polydopamine (PDA) were encapsulated inside lysine-proline-valine (KPV)-modified deformable liposomes (KPV-Lipos). Owing to their phospholipid bilayer flexibility and the specific affinity for melanocortin 1 receptor (MC1R), KPV-Lipos exhibited 1.43-fold greater skin deposition than traditional liposomes. The binding of KPV and its receptor also contributed to activating the cAMP-tyrosinase (TYR) signaling pathway, improving the endogenous melanin content. In addition, PDA mimicked melanosomes as it effectively increased the exogenous melanin content and scavenged ROS. Meanwhile, MPS inhibited inflammatory cytokine secretion, limiting the depigmented area. Ultimately, the biomimetic melanosomes affected the skin color of mice with H2O2-induced vitiligo. These melanosomes show potential as a universal platform for the self-supply of melanin by self-driven melanin synthesis with exogenous supplementation. Furthermore, this study offers ideas for the production of artificial packed melanosome substitutes for melanocyte-related diseases.

Abstract
Background Patients with vitiligo experience reduced quality of life. Objective To comprehensively describe the available evidence for psychosocial burden in vitiligo. Methods A systematic review of observational studies and clinical trials identified using PubMed, EMBASE, Scopus, and the Cochrane databases was performed through 1 March, 2021, to assess psychosocial comorbidities in vitiligo. Two independent reviewers performed an assessment of articles and extracted data for qualitative synthesis. Results Included studies (N = 168) were published between 1979 and 1 March, 2021; 72.6% were published since 2010. Disorders including or related to depression (41 studies, 0.1–62.3%) and anxiety (20 studies, 1.9–67.9%) were the most commonly reported. The most prevalent psychosocial comorbidities were feelings of stigmatization (eight studies, 17.3–100%), adjustment disorders (12 studies, 4–93.9%), sleep disturbance (seven studies, 4.6–89.0%), relationship difficulties including sexual dysfunction (ten studies, 2.0–81.8%), and avoidance or restriction behavior (12.5–76%). The prevalence of most psychosocial comorbidities was significantly higher vs healthy individuals. Factors associated with a significantly higher burden included female sex, visible or genital lesions, age < 30 years (particularly adolescents), and greater body surface area involvement, among others. The most commonly reported patient coping strategy was lesion concealment. Limitations Available studies were heterogeneous and often had limited details; additionally, publication bias is possible. Conclusions The results of this systematic review show that vitiligo greatly affects psychosocial well-being. The extent of psychosocial comorbidities supports the use of multidisciplinary treatment strategies and education to address the vitiligo-associated burden of disease.

Abstract
Introduction: Narrow-band (NB) ultraviolet B (UVB) phototherapy has been shown to halt disease progression in vitiligo, but whether there is any difference in the response to NB-UVB seen in patients with progressive vitiligo versus non-progressive vitiligo has not been evaluated. Objectives: To evaluate the effect of NB-UVB on progressive versus non-progressive non-segmental vitiligo. Study Design: Prospective observational comparative study. Duration: April 2016-November 2017. Methods: Adult patients having non-segmental vitiligo involving 2-50% body surface area were divided into two subsets; patients developing >5 lesions in the last 1 month or >15 lesions in the last 3 months (progressive vitiligo, Group I) and patients with static disease for the last 6 months (non-progressive vitiligo, Group II). Both groups were treated with NB-UVB for 6 months (26 weeks) cumulatively and its efficacy in halting disease progression, re-pigmentation, side effects and psychosocial impact were evaluated. Results: Nineteen out of 24 patients with progressive vitiligo had arrest of disease progression. Rest five patients developed lesions at a slower pace. Group II had earlier onset of re-pigmentation, while Group I had more NB-UVB fluence (34.73 J/cm2 vs 25.2 J/cm2, P value = 0.034), more time for the fluence to be fixed (P value = 0.001) and more pruritus (P value = 0.001). Conclusions: NB-UVB has the potential to halt disease progression in some patients with progressive vitiligo; but is associated with more total NB-UVB fluence and time taken for fixing it. Progressive vitiligo patients have more pruritus as compared to patients with non-progressive vitiligo.

Abstract
Background: Today's machine-learning based dermatologic research has largely focused on pigmented/non-pigmented lesions concerning skin cancers. However, studies on machine-learning-aided diagnosis of depigmented non-melanocytic lesions, which are more difficult to diagnose by unaided eye, are very few. Objective: We aim to assess the performance of deep learning methods for diagnosing vitiligo by deploying Convolutional Neural Networks (CNNs) and comparing their diagnosis accuracy with that of human raters with different levels of experience. Methods: A Chinese in-house dataset (2,876 images) and a world-wide public dataset (1,341 images) containing vitiligo and other depigmented/hypopigmented lesions were constructed. Three CNN models were trained on close-up images in both datasets. The results by the CNNs were compared with those by 14 human raters from four groups: expert raters (>10 years of experience), intermediate raters (5-10 years), dermatology residents, and general practitioners. F1 score, the area under the receiver operating characteristic curve (AUC), specificity, and sensitivity metrics were used to compare the performance of the CNNs with that of the raters. Results: For the in-house dataset, CNNs achieved a comparable F1 score (mean [standard deviation]) with expert raters (0.8864 [0.005] vs. 0.8933 [0.044]) and outperformed intermediate raters (0.7603 [0.029]), dermatology residents (0.6161 [0.068]) and general practitioners (0.4964 [0.139]). For the public dataset, CNNs achieved a higher F1 score (0.9684 [0.005]) compared to the diagnosis of expert raters (0.9221 [0.031]). Conclusion: Properly designed and trained CNNs are able to diagnose vitiligo without the aid of Wood's lamp images and outperform human raters in an experimental setting.

Abstract
BACKGROUND Vitiligo management is challenging and requires long-term adherence of patients who often complain of the burden associated with treatment. OBJECTIVE To develop and validate a patient reported measurement of the burden of treatment in vitiligo. METHODS The study was nested within the ComPaRe Vitiligo e-cohort, an online e-cohort of vitiligo patients in France. Items were derived from a literature review and from the qualitative analysis of a survey using open-ended questions of 204 patients with Vitiligo. Construct validity of the resulting instrument was assessed by comparing the instrument's score to the Dermatology Life Quality Index (DLQI), Vitiligo Impact Patient score (VIPs) and Treatment Burden Questionnaire (TBQ) scores. Reliability was assessed by test-retest with 15 ± 10 days of interval between both assessments. RESULTS In total, 343 adult participants participated in the validation of the Vitiligo Treatment Impact score (VITs). The VITs is a 19-item questionnaire assessing the burden of treatment in patients with vitiligo with results suggesting four domains ('Finding a doctor', 'Phototherapy', 'Topical treatment' and 'Impact on outdoor activities and photoprotection'). The VITs total score was well correlated with the DLQI, VIP and TBQ scores. Agreement between test and retest was good (ICC 0.705, 95% CI 0.491-0.818). CONCLUSIONS We developed a patient reported measurement of the burden of treatment in vitiligo with good psychometric properties.

Abstract
Vitiligo is an autoimmune disease of the skin characterized by epidermal melanocyte loss resulting in white patches, with an approximate prevalence of 0.5-2% worldwide. Several precipitating factors by chemical exposure and skin injury present commonly in patients with vitiligo. Although the diagnosis appears to be straightforward for the distinct clinical phenotype and specific histological features, vitiligo provides many challenges including chronicity, treatment resistance, frequent relapse, associated profound psychosocial effect, and negative impact on quality of life. Multiple mechanisms are involved in melanocyte disappearance, including genetics, environmental factors, and immune-mediated inflammation. Compelling evidence supports the melanocyte intrinsic abnormalities with poor adaptation to stressors leading to instability and release of danger signals, which will activate dendritic cells, natural killer cells, and innate lymphoid cells to initiate innate immunity, ultimately resulting in T-cell mediated adaptive immune response and melanocyte destruction. Importantly, the cross- talk between keratinocytes, melanocytes, and immune cells, such as interferon (IFN)-γ signaling pathway, builds inflammatory loops that give rise to the disease deterioration. Improved understanding of the immune pathogenesis of vitiligo has led to the development of new therapeutic options including Janus kinase (JAK) inhibitors targeting IFN-γ signaling pathways, which can effectively reverse depigmentation. Furthermore, definition of treatment goals and integration of comorbid diseases into vitiligo management have revolutionized the way vitiligo is treated. In this review, we highlight recent developments in vitiligo clinical aspects and immune pathogenesis. Our key objective is to raise awareness of the complexity of this disease, the potential of prospective therapy strategies, and the need for early and comprehensive management.

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
Introduction
Vitiligo is an acquired pigmentary disorder of unknown etiology, clinically characterized by whitish macules caused by selective loss of melanocytes. There are many melanocytes in the human cochlea. Recent studies have suggested a direct relation between cochlear dysfunction and decreased amounts of melanin.
Objective
To determine the effect of vitiligo on auditory function.
Methods
The present prospective, case control study was performed over a period of 1 year in patients between 15 and 40 years old with nonsegmental disease and the same number of controls. Pure tone audiometry (PTA) and Otoacoustic emission (OAE) were performed to analyze the correlation between vitiligo and auditory function.
Results
The mean pure tone audiometric threshold in the right ear at 0.5, 8 kHz, and in the left ear at the frequency of 8 kHz in the case group were significantly higher as compared with controls. The average band reproducibility (%) in the right and left ear of controls was significantly higher at the frequency of 4 kHz as compared with cases. It has been observed that signal to noise ratio was statistically higher at the frequency of 5kHz in the right ear and at 2, 3, and 5kHz in the left ear in controls as compared with cases. On the basis of disease type and duration of disease; mean pure tone audiometric threshold, average band reproducibility and signal to noise ratio, no significant effect was observed in the present study.
Conclusion
Vitiligo has an effect on cochlear function irrespective of the duration or distribution of the disease.

Abstract
Introduction: Treatment with immune checkpoint inhibitors in melanoma patients can cause immune-related adverse effects, such as vitiligo. In vitiligo, specific autoimmunity against melanocytes results in depigmentation of the skin. Melanoma-associated vitiligo occurring in melanoma patients treated with immune checkpoint inhibitors can be seen as a good prognostic sign as higher survival rates in melanoma-associated vitiligo cases have been reported.Areas covered: This review gives an insight into the pathophysiology, clinical presentation, and management of melanoma-associated vitiligo caused by immune checkpoint inhibitors.Expert opinion: Development of melanoma-associated vitiligo induced by immune checkpoint inhibitors could be a good clinical marker for response and overall survival. Induction of vitiligo in these patients could also potentially lead to better response and survival rates. Further research should focus on several aspects of melanoma-associated vitiligo, such as better screening and registration, more understanding of pathophysiology of the type of immune response and the predictive value of melanoma-associated in patients treated with immune checkpoint inhibitors.

Abstract
BACKGROUND Shared decision-making tools (SDMt) are visual tools developed to promote joint medical decisions between physicians and patients. There is a paucity of such tools in dermatology. OBJECTIVES To develop and validate a SDMt for use in specialized consultation for vitiligo. METHODS A prospective cross-sectional study was carried out from March 2019 to March 2020. We first conducted a qualitative study of topics discussed by patients and clinicians during therapeutic decision-making in the setting of a specialized consultation for vitiligo using an anchored-theory method, which allowed conceptualization of the SDMt. The usefulness of the SDMt was evaluated by a working group of multidisciplinary health workers and patients with vitiligo. Consensus on the final tool was obtained through an e-Delphi method. RESULTS We recruited 30 patients with vitiligo for the qualitative study, which identified 91 topics related to therapeutic decision-making. Hierarchical clustering analysis confirmed the distribution of these topics in two subgroups (general treatment goals and priorities, and topics specific to each treatment). The consensus of a multidisciplinary group was used to develop the SDMt. The tool was comprised of eight A5 cards, which addressed face repigmentation; body repigmentation (limited area); body repigmentation (extended area); partial or complete depigmentation; coping with the disease; stabilization of disease; maintaining repigmentation; and disease information. Cognitive interviews confirmed the satisfaction, readability and usefulness of the SDMt. The SDMt was then translated and culturally validated in English. CONCLUSIONS We developed a tool for shared decision-making in nonsegmental vitiligo, which we translated and cross-culturally validated in a US patient population with vitiligo to ensure its generalizability.

Int J Dermatol 2021; 60:868-876. [PMID: 33729554 DOI: 10.1111/ijd.15464] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Revised: 12/14/2020] [Accepted: 01/20/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND There is limited evidence supporting the use of alternative treatments for patients with nonstable vitiligo. OBJECTIVE This study aimed to review the effects of oral mini-pulse (OMP) therapy in the management of nonsegmental vitiligo. METHODS The following databases were searched between inception and May 2020 for relevant studies: Scopus, Web of Science, MEDLINE, and Embase. All randomized controlled trials that compared OMP therapy with any other active treatment or placebo for nonstable vitiligo were included. The Cochrane's risk of bias tool was used to evaluate the risk of bias (ROB) in selected studies, and the overall quality of evidence of each outcome was assessed using the Grading Recommendations, Assessment, Development, and Evaluations (GRADE) system. RESULTS Four studies met our selection criteria. All of them were conducted in India and included 246 patients. OMP therapy included betamethasone or dexamethasone. The duration of treatment was 6 months in all studies. Up to 32% of patients achieved a repigmentation rate of >75% when OMP therapy was administered as monotherapy. No difference was observed between OMP therapy and other treatments in arresting the disease, and weight gain was the most frequent adverse effect. The overall ROB in all included studies was relatively high because of the randomization process, outcome measurement and informed selection of outcomes. CONCLUSION Based on the findings of these studies, OMP therapy did not demonstrate additional value compared with other treatments. Hence, there is an urgent need to conduct high-quality clinical trials to evaluate this therapy.

Abstract
Background Pemphigus is a rare but life-threatening autoimmune skin disease characterized by blistering on skin and/or mucous membranes. The physiological process of blister formation involves IgG antibodies against the desmogleins (Dsgs) and desmocollins (Dscs). Additional autoAbs have also been suggested to mediate the disease heterogeneity, such as anti-thyroid peroxidase (anti-TPO) and antithyroglobulin (anti-Tg) antibodies, the essential culprits of the immune system in autoimmune thyroid diseases. Purpose To investigate the levels and antibody positivity of anti-TPO and anti-Tg antibodies in pemphigus patients. Methods Antibody positivity and levels of anti-TPO and anti-Tg antibodies in pemphigus patients as compared to healthy controls were examined. A meta-analysis was conducted by reviewing six similar studies. Results 98 Chinese pemphigus patients and 65 healthy controls were enrolled in the study. Our meta-analysis revealed a significant correlation between increased presence of positive anti-TPO and anti-Tg antibodies and pemphigus, particularly for pemphigus vulgaris (PV). Such correlation was also observed in our own hospitalized PV patients, but not in pemphigus foliaceus (PF) patients. In addition, the status of anti-TPO and anti-Tg antibodies were also compared between females and males within PV patients, PF patients or controls, as well as compared for females or males between pemphigus patients and controls. In the analysis of T cell counts, we found abnormal low CD3 + T cell counts (< 690 n/µl) were only detected in patients whose thyroid antibody levels were less than 20 IU/ml. Conclusion Pemphigus patients showed higher levels and antibody positivity of anti-TPO and anti-Tg antibodies than healthy controls. Further investigations are needed to identify the pathogenic functions of these antibodies in pemphigus, as well as to identify the potential shared susceptibility genes.

Abstract
Excimer light, topical vitamin D analogues, and topical steroids have been reported to be effective treatments for vitiligo. However, monotherapy often demonstrates unfavorable results for acral vitiligo. This study aimed to evaluate the efficacy and safety of combination treatment with 308-nm excimer light and topical calcipotriol or topical clobetasol ointment for acral vitiligo. A prospective, randomized, double-blind, and intraindividual study was conducted. Combination treatment (excimer light and topical medication) was applied in the first 12 weeks, and monotherapy (topical medication alone) was used in the later 12 weeks. Both hands were irradiated with excimer light three times a week for 12 weeks. Calcipotriol ointment was randomly assigned to one hand, whereas clobetasol ointment was assigned to the other hand. The ointments were applied twice daily for a total of 24 weeks. Repigmentation, clinical improvement, and adverse reactions were assessed. A total of 26 hands completed the study. Of the hands treated with excimer light and calcipotriol, approximately 8% achieved excellent repigmentation at the end of the combination treatment period and 23% achieved good to excellent improvement after 12 weeks of calcipotriol monotherapy. More than 85% and 77% of the hands treated with calcipotriol-based and clobetasol-based regimens showed some repigmentation at the end of the study, respectively (P < .05). Nevertheless, no significant difference was found between the treatments. No serious adverse reactions were observed. In conclusion, the combination of excimer light and topical calcipotriol followed by topical calcipotriol alone is effective and might be a promising treatment regimen for acral vitiligo.

Abstract
Vitiligo is a prevalent destructive melanocyte skin disease that negatively affects the patients' life in terms of self-esteem. Suction blister and dermabrasion plus 5-fluorouracil are effective treatments for vitiligo. The present study was conducted to compare the outcomes of these two techniques. The present clinical trial was conducted on 36 patients with persistent refractory vitiligo which defined as the lack of any new or progressed lesion during the previous year as well as no responding to conventional therapies of vitiligo including topical treatments and phototherapy. Individuals with two vitiligo patches, with similar baseline Vitiligo Area Severity Index (VASI) scores were randomly allocated to dermabrasion plus 5-fluorouracil or suction blister treatments. VASI and repigmentation scores were measured and compared at the baseline, four, and 12 weeks after performing the procedures. Both of the approaches accompanied with significant improvement in both entities of VASI and repigmentation scores (P value < .05) at the end of the study, besides the trend of VASI and repigmentation scores between the two groups revealed insignificant difference (P > .05). The short-term follow-up of the patients was the limitation of this study. The present findings suggested that both surgical techniques of dermabrasion plus 5-fluorouracil and suction blister posed acceptable outcomes within 12-week follow-up.

Effect of platelet-rich plasma on the outcome of mini-punch grafting procedure in localized stable vitiligo: Clinical evaluation and relation to lesional basic fibroblast growth factor. Dermatol Ther 2021; 34:e14738. [PMID: 33403743 DOI: 10.1111/dth.14738] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2020] [Revised: 12/14/2020] [Accepted: 12/31/2020] [Indexed: 12/18/2022]
Abstract
Surgical methods are favorably used for treatment of stable vitiligo, and platelet-rich plasma (PRP) can be added to augment the effect. The additive value of PRP, however, remains elusive. Basic fibroblast growth factor (bFGF) is released from activated platelets with a capacity for stimulating melanocyte proliferation and migration. The treatment outcomes for the mini-punch grafting (MPG)/phototherapy treatment with and without PRP were assessed and the relation between bFGF and the obtained results were evaluated. Thirty-four vitiliginous patches, two per each patient with stable vitiligo, were enrolled in this intrapatient-controlled study and treated with autologous MPG and subsequent exposure to phototherapy with and without enhancement via PRP procedure at the time of the procedure, and monthly for the subsequent 3 months. Re-pigmentation assessment via vitiligo scores as well as measurement of lesional bFGF were done. PRP assistance to MPG/phototherapy treatment resulted in earlier re-pigmentation at week 8. However, this enhancement effect vanished at the study end (week 20) as ideal re-pigmentation (>75% re-pigmentation) was encountered in 10 patches (58.8%) treated with MPG/phototherapy modality, and in 12 patches (70.6%) treated with PRP-assisted method without significant difference between them. Lesional bFGF increased after both treatments with a higher expression with PRP assistance but without clinical reflection on the final outcome. PRP can speed the re-pigmentation response for MPG/phototherapy procedure without any significant effect on the final outcome.

Abstract
BACKGROUND Evidence for the effectiveness of vitiligo treatments is limited. OBJECTIVES To determine the effectiveness of (i) handheld narrowband UVB (NB-UVB) and (ii) a combination of potent topical corticosteroid (TCS) and NB-UVB, compared with TCS alone, for localized vitiligo. METHODS A pragmatic, three-arm, placebo-controlled randomized controlled trial (9-month treatment, 12-month follow-up). Adults and children, recruited from secondary care and the community, aged ≥ 5 years and with active vitiligo affecting < 10% of skin, were randomized 1 : 1 : 1 to receive TCS (mometasone furoate 0·1% ointment + dummy NB-UVB), NB-UVB (NB-UVB + placebo TCS) or a combination (TCS + NB-UVB). TCS was applied once daily on alternating weeks; NB-UVB was administered on alternate days in escalating doses, adjusted for erythema. The primary outcome was treatment success at 9 months at a target patch assessed using the participant-reported Vitiligo Noticeability Scale, with multiple imputation for missing data. The trial was registered with number ISRCTN17160087 on 8 January 2015. RESULTS In total 517 participants were randomized to TCS (n = 173), NB-UVB (n = 169) and combination (n = 175). Primary outcome data were available for 370 (72%) participants. The proportions with target patch treatment success were 17% (TCS), 22% (NB-UVB) and 27% (combination). Combination treatment was superior to TCS: adjusted between-group difference 10·9% (95% confidence interval 1·0%-20·9%; P = 0·032; number needed to treat = 10). NB-UVB alone was not superior to TCS: adjusted between-group difference 5·2% (95% CI - 4·4% to 14·9%; P = 0·29; number needed to treat = 19). Participants using interventions with ≥ 75% expected adherence were more likely to achieve treatment success, but the effects were lost once treatment stopped. Localized grade 3 or 4 erythema was reported in 62 (12%) participants (including three with dummy light). Skin thinning was reported in 13 (2·5%) participants (including one with placebo ointment). CONCLUSIONS Combination treatment with home-based handheld NB-UVB plus TCS is likely to be superior to TCS alone for treatment of localized vitiligo. Combination treatment was relatively safe and well tolerated but was successful in only around one-quarter of participants.

Abstract
Vitiligo is a relatively common, acquired hypopigmentary disorder caused by the loss of epidermal melanocytes. It is characterized by asymptomatic, well-circumscribed round to oval-shaped whitish patches that vary in size. Depending on various clinical features, vitiligo is classified into several types, that is, non-segmental, segmental, and undetermined/unclassified vitiligo. The uniform classification of vitiligo is very important in predicting its clinical course and prognosis and communication among researchers. In particular, segmental vitiligo is a highly distinctive subtype of vitiligo considering its clinical features and prognosis. It usually has an onset early in life and spreads rapidly within the affected area limited to one segment of the integument. Signs of vitiligo activity such as Koebnerʼs phenomenon, trichrome vitiligo, inflammatory vitiligo, and confetti-like lesions give useful information to start treatments to block the progression of the disease. Lastly, other hypopigmentary disorders should be distinguished from vitiligo to make the correct diagnosis and prescribe the right treatment. In this report, I review the clinical features of vitiligo, various subtypes according to classification, and the importance for differential diagnosis of hypopigmentary disorders from vitiligo.

Abstract
Vitiligo is an acquired depigmenting skin disorder that affects 0.5% to 2% of the population. Skin lesions from vitiligo, white macules and patches on the skin, can pose a substantial psychological burdencan, causing a significant decrease in one’s quality of life. Recent basic and clinical studies have found that vitiligo is an autoimmune disorder, mediated by CD8+ T-cell and interferon-γ-mediated cytokine/chemokines. Although no treatment modality presents a complete cure for vitiligo, current treatment modalities have a modest effect on vitiligo by reversing the disease’s progression, inducing its stabilization, and promoting melanocyte regeneration. Current non-surgical treatment modalities include topical corticosteroids, topical calcineurin inhibitors, systemic corticosteroids, and phototherapy such as narrowband ultraviolet B phototherapy and excimer laser. In addition, clinicians have used and combined non-surgical treatment modalities based on the activity and extent of vitiligo. Moreover, considering the high risk of vitiligo relapse, maintenance therapy for re-pigmented lesions has also been introduced. Lastly, based on the results of recent translational research, new and emerging treatment modalities have been introduced, such as Janus kinase inhibitors. This review presents an overview of the current non-surgical treatment modalities for vitiligo and discusses emerging treatments.

Abstract
Since nonsurgical treatment of vitiligo is not always successful, surgical interventions are viable options for patients with refractory vitiligo. Surgical treatment is a method in which melanocytes of normal skin are transplanted into vitiligo lesions and provided as a repigmentation source. Such treatments are primarily divided into tissue grafting and cellular grafting, depending on the nature of the graft. Tissue grafting includes split-thickness skin grafting, suction blister grafting, punch grafting, hair follicle transplantation, and smashed-skin grafting. Cellular grafting includes non-cultured epidermal cell suspension transplantation, non-cultured follicular cell suspension transplantation, and cultured epidermal cell suspension transplantation. Among these, suction blister grafting and micro-punch grafting have been widely performed for localized refractory vitiligo, and non-cultured epidermal cell suspension transplantation is adopted as the standard treatment for extensive vitiligo. Research on cultured cellular grafting to treat larger vitiligo areas is also ongoing. Selecting patients with stable vitiligo that has not spread for over 12 months is the most critical factor in the surgical outcome. It is also important to choose an appropriate surgical modality for each patient, and a combination of various procedures often improves the overall outcome. In conclusion, surgical intervention can be an effective and safe option for patients with vitiligo refractory to conventional treatments. Non-cultured epidermal cell suspension transplantation, which was denied by New Health Technology Assessment in Korea, should be approved to benefit patients with refractory vitiligo.

Abstract
BACKGROUND Vitiligo is an acquired depigmenting skin disease which is often accompanied by mental distress. There are numerous studies dedicated to local and global prevalence of depression in patients with vitiligo but anxiety has not been recognized as a major mental problem within named population. We aimed to evaluate the prevalence of anxiety among patients with vitiligo from different countries and to compare it with patients suffering from eczema, psoriasis, and acne. METHODS In November 2019, we conducted a systematic search for observational studies that examined the prevalence of anxiety in vitiligo patients. Fifteen studies comprising 1176 patients with vitiligo were included to our systematic review. RESULTS The general prevalence of anxiety among vitiligo patients was equal to 35.8%. Statistically significant difference in anxiety rates was found among female and male patients (47.32% vs 42.4%) (P = 0.03), but the clinical relevance of this issue remains arguable. In addition, the pooled odds ratio among vitiligo and non-vitiligo patients did not indicate a statistical significance among patients coming from different continents. CONCLUSIONS The pooled prevalence of anxiety among vitiligo patients worldwide was comparable to other severe skin disorders. This finding accentuates the necessity of anxiety awareness in management of patients with skin diseases.

Abstract
BACKGROUND Systematic reviews suggest that narrowband ultraviolet B light combined with treatments such as topical corticosteroids may be more effective than monotherapy for vitiligo. OBJECTIVE To explore the clinical effectiveness and cost-effectiveness of topical corticosteroid monotherapy compared with (1) hand-held narrowband ultraviolet B light monotherapy and (2) hand-held narrowband ultraviolet B light/topical corticosteroid combination treatment for localised vitiligo. DESIGN Pragmatic, three-arm, randomised controlled trial with 9 months of treatment and a 12-month follow-up. SETTING Sixteen UK hospitals - participants were recruited from primary and secondary care and the community. PARTICIPANTS Adults and children (aged ≥ 5 years) with active non-segmental vitiligo affecting ≤ 10% of their body area. INTERVENTIONS Topical corticosteroids [mometasone furoate 0.1% (Elocon®, Merck Sharp & Dohme Corp., Merck & Co., Inc., Whitehouse Station, NJ, USA) plus dummy narrowband ultraviolet B light]; narrowband ultraviolet B light (narrowband ultraviolet B light plus placebo topical corticosteroids); or combination (topical corticosteroids plus narrowband ultraviolet B light). Topical corticosteroids were applied once daily on alternate weeks and narrowband ultraviolet B light was administered every other day in escalating doses, with a dose adjustment for erythema. All treatments were home based. MAIN OUTCOME MEASURES The primary outcome was self-assessed treatment success for a chosen target patch after 9 months of treatment ('a lot less noticeable' or 'no longer noticeable' on the Vitiligo Noticeability Scale). Secondary outcomes included blinded assessment of primary outcome and percentage repigmentation, onset and maintenance of treatment response, quality of life, side effects, treatment burden and cost-effectiveness (cost per additional successful treatment). RESULTS In total, 517 participants were randomised (adults, n = 398; and children, n = 119; 52% male; 57% paler skin types I-III, 43% darker skin types IV-VI). At the end of 9 months of treatment, 370 (72%) participants provided primary outcome data. The median percentage of narrowband ultraviolet B light treatment-days (actual/allocated) was 81% for topical corticosteroids, 77% for narrowband ultraviolet B light and 74% for combination groups; and for ointment was 79% for topical corticosteroids, 83% for narrowband ultraviolet B light and 77% for combination. Target patch location was head and neck (31%), hands and feet (32%), and rest of the body (37%). Target patch treatment 'success' was 20 out of 119 (17%) for topical corticosteroids, 27 out of 123 (22%) for narrowband ultraviolet B light and 34 out of 128 (27%) for combination. Combination treatment was superior to topical corticosteroids (adjusted risk difference 10.9%, 95% confidence interval 1.0% to 20.9%; p = 0.032; number needed to treat = 10). Narrowband ultraviolet B light was not superior to topical corticosteroids (adjusted risk difference 5.2%, 95% confidence interval -4.4% to 14.9%; p = 0.290; number needed to treat = 19). The secondary outcomes supported the primary analysis. Quality of life did not differ between the groups. Participants who adhered to the interventions for > 75% of the expected treatment protocol were more likely to achieve treatment success. Over 40% of participants had lost treatment response after 1 year with no treatment. Grade 3 or 4 erythema was experienced by 62 participants (12%) (three of whom were using the dummy) and transient skin thinning by 13 participants (2.5%) (two of whom were using the placebo). We observed no serious adverse treatment effects. For combination treatment compared with topical corticosteroids, the unadjusted incremental cost-effectiveness ratio was £2328.56 (adjusted £1932) per additional successful treatment (from an NHS perspective). LIMITATIONS Relatively high loss to follow-up limits the interpretation of the trial findings, especially during the post-intervention follow-up phase. CONCLUSION Hand-held narrowband ultraviolet B light plus topical corticosteroid combination treatment is superior to topical corticosteroids alone for treatment of localised vitiligo. Combination treatment was relatively safe and well tolerated, but was effective in around one-quarter of participants only. Whether or not combination treatment is cost-effective depends on how much decision-makers are willing to pay for the benefits observed. FUTURE WORK Development and testing of new vitiligo treatments with a greater treatment response and longer-lasting effects are needed. TRIAL REGISTRATION Current Controlled Trials ISRCTN17160087.
