RESUMO

IMPORTANCE: Vitiligo is a chronic skin disorder causing depigmentation. There is a lack of evidence-based medical evidence regarding ruxolitinib efficacy and safety for vitiligo. OBJECTIVE: To assess the efficacy and safety of ruxolitinib cream in the treatment of vitiligo. METHODS: The databases of PubMed, Embase, and Cochrane Library were searched. The literature screening was independently conducted by two reviewers. DATA EXTRACTION AND SYNTHESIS: For continuous variables, weighted mean difference (WMD) along with a 95% confidence interval (CI) was performed. For dichotomous outcomes, we calculated the odds ratios (ORs) or risk ratios (RRs), and their corresponding 95% CIs. The certainty of evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). MAIN OUTCOMES AND MEASURES: Symptoms, quality of life, and safety were evaluated using various measures, including the Facial Vitiligo Area Scoring Index (F-VASI), Total Vitiligo Area Scoring Index (T-VASI), Facial Body Surface Area (F-BAS), Total Body Surface Area (T-BAS) and Treatment-emergent Adverse Events (TEAEs). RESULTS: Three trials, involving a total of 830 participants from nine countries were included (female 388, 46.7%, male 442, 53.3%). The meta-analysis demonstrated a significant increase in the likelihood of participants achieving F-VASI75 (OR, 4.34 [95% CI 2.67-7.06]; high), F-VASI50 (OR 4.71 [95% CI 3.24-6.84]; high), T-VASI75 (OR 2.78 [95% CI 1.10-7.00]; moderate), and T-VASI50 (OR 4.47 [95% CI 2.52-7.92]; high) when compared ruxolitinib to vehicle. Ruxolitinib was associated with more lowered percentage change of F-VASI scores (MD - 32.79 [95% CI - 36.37 to - 29.21]; moderate), and T-VASI scores (MD - 20.22 [95% CI - 23.11 to - 17.33]; moderate) from baseline compared to vehicle. There may not be a significant difference in the occurrence of TEAEs between ruxolitinib and vehicle (RR 1.46 [95% CI 0.85-2.49]; high). CONCLUSIONS: The findings suggest that ruxolitinib cream holds promise as a treatment option for vitiligo. Further long-term studies are needed to assess its sustained efficacy and safety profile.

RESUMO

OBJECTIVE: The relationship between vitiligo and cardiovascular diseases remains controversial. This study aimed to systematically review the evidence comparing cardiovascular disease risk factors between patients with vitiligo and controls and to perform a meta-analysis of the results. DATA SOURCES: A comprehensive database search was performed for all studies in PubMed, EMBASE, and Cochrane Central Register databases from inception to November, 2023. The main keywords used were vitiligo, hypertension, diabetes, hyperlipidemia, metabolic syndrome, obesity, smoking, alcohol consumption, C-reactive protein, and homocysteine. STUDY SELECTION: Only observational studies and no randomized controlled trials were included. Of the 1269 studies initially selected, the full texts of 108 were assessed for eligibility, and 74 were ultimately included in the analysis. DATA EXTRACTION AND SYNTHESIS: Three reviewers independently extracted the following data: study design, number and characteristics of participants, inclusion indicators, and disease duration. A meta-analysis of the single-group rates was performed for the diabetes, hypertension, hyperlipidemia, and obesity groups. Random-effects or fixed-effects models were used to calculate the sample-size weighted averages for the indicators included in the studies. MAIN OUTCOMES AND MEASURES: The primary outcomes were co-morbidity analysis and co-morbidity rates of vitiligo with metabolic syndrome, obesity, hyperlipidemia, hypertension, and diabetes mellitus. Secondary outcomes were factors associated with vitiligo and cardiovascular disease. RESULTS: This meta-analysis concluded that comorbidities in patients with vitiligo included metabolic syndrome, diabetes, obesity, hyperlipidemia, and hypertension, with comorbidity rates of 28.3%, 6.0%, 38.5%, 43.0%, and 15.8%, respectively. Simultaneously, we showed that the vitiligo group differed significantly from the control group in the following aspects: fasting blood glucose, insulin, systolic and diastolic blood pressure, total cholesterol, triglycerides, low-density lipoprotein, high-density lipoprotein, homocysteine, C-reactive protein, smoking, and alcohol consumption. However, no significant differences were observed between the vitiligo and control groups in terms of waist circumference, body mass index, or phospholipid levels. LIMITATIONS: The vast majority of the studies were from Eastern countries; therefore, extrapolation of these results to Western populations is questionable. The significant heterogeneity may be due to different protocols, doses, durations, center settings, population registries, etc., which severely compromise the validity of the results. CONCLUSION: This study summarized not only the factors associated with, but also those not associated with, cardiovascular disease in patients with vitiligo. This study provides a foundation for the prevention and treatment of cardiovascular disease in patients with vitiligo.

RESUMO

Addison´s disease can form part of type 2 autoimmune polyglandular syndrome. The article reports the case of a 41-year-old female patient with hypothyroidism and vitiligo, who came to the emergency department complaining of asthenia that had worsened in recent months, as well as anorexia, nausea, and weight loss (6 kg in a year). Cutaneous hyperpigmentation was the main finding on physical examination, together with vitiligo lesions on the face, hands, and armpits. Further study revealed a low serum cortisol level, normal urine-free cortisol, and an elevated adrenocorticotropic hormone (ACTH). Antiperoxidase antibodies and 17-alpha-hidroxylase antibodies were both positive. Treatment was started with prednisolone and fludrocortisone, and a good clinical response was obtained. This case report aims to draw attention to the high level of clinical suspicion required to diagnose Addison´s disease and the need to screen actively for other potentially associated autoimmune diseases that may be associated.

RESUMO

OBJECTIVE: This study aimed to determine the prevalence of vitiligo and associated factors among patients visiting the dermatologic outpatient departments at Tibebe Ghion Specialized Hospital and Addisalem Primary Hospitals, Bahir Dar, Ethiopia, from September 15 to November 15, 2023. RESULTS: Among the 460 patients studied, 243 (52.8%) were female, with the majority (28.9%) aged between 25 and 34 years. The overall prevalence of vitiligo was found to be 7.4% (34 patients). Significant predictors of vitiligo included rural residence (AOR: 3.18; 95% CI: 1.10-9.18), family history of vitiligo (AOR: 2.20; 95% CI: 2.16-4.76), and aggravating factors such as trauma (AOR: 1.08; 95% CI: 1.01-2.08). The highest prevalence was observed in the 14-24 age group. These findings suggest the importance of awareness campaigns focusing on the causes, symptoms, and treatments of vitiligo, particularly among young adults in rural areas.

RESUMO

Previous observational studies have suggested that gut microbiota might be associated with vitiligo. However, owing to the limitations in observational studies of reverse causality and confounders, it remains unclear that whether and how the causal relationships exist. The results suggested that pylum.Bacteroidetes, family.BacteroidalesS24.7, genus.LachnospiraceaeND3007, genus.Marvinbryantia are protective factors for vitiligo. Conversely, family.Lachnospiraceae, order.Burkholderiales, genus.Adlercreutzia, genus.Catenibacterium and genus.Lachnospira are risk factors for vitiligo. In addition, the causative connection between dietary factors and the gut microbiota associated with vitiligo was also investigated. The results revealed that 'alcohol intake versus 10 years pervious' results in a reduction in the abundance of genus.Lachnospiraceae ND3007 and family.BacteroidalesS24.7, bread intake leads to a reduction of genus.Marvinbryantia, 'average weekly red wine intake' is linked to a decrease in the abundance of order.Burkholderiales, tea intake is associated with an augmentation in the abundance of genus.Catenibacterium, salad/raw vegetable intake elevates the abundance of order.Burkholderiales. In summary, this Mendelian randomization study substantiates potential causal effects of gut microbiota on vitiligo. Modulating the gut microbiota through regulating dietary composition may be a novel strategy for preventing vitiligo.

RESUMO

Efficacy and safety of ritlecitinib (an oral JAK3/TEC family kinase inhibitor) were evaluated in patients with nonsegmental vitiligo (NSV) across Fitzpatrick skin types (FSTs). Patients with FST I-III ('light skin'; n = 247) and FST IV-VI ('dark skin'; n = 117) received once-daily ritlecitinib 50 mg (with/without 4-week loading dose), low-dose ritlecitinib or placebo for 24 weeks. At baseline, patients with light skin displayed higher CLM-1 and NCR1 serum levels than patients with dark skin (p < 0.05). At 24 weeks, ritlecitinib 50 mg improved the extent of depigmentation measured by percent change from baseline in facial-vitiligo area scoring index (placebo-adjusted mean difference [90% CI]) in patients with light (-15.2 [-24.7, -5.8]; p = 0.004) and dark (-37.4 [-50.3, -24.4]; p < 0.0001) skin, with continuous re-pigmentation through week 48. Treatment-emergent adverse events were similar across FSTs. At weeks 4 and 24, ritlecitinib 50 mg reduced CXCL11 serum levels (p < 0.001) in patients with light skin, whereas patients with dark skin had increased levels at week 4 (p = 0.05) and no significant change at week 24. Ritlecitinib 50 mg decreased IL-9 and IL-22 expression levels in dark skin compared with light skin (qPCR; p < 0.05). These differences in immune dysregulations may explain why NSV patients with dark skin respond to therapy earlier than patients with light skin.

RESUMO

Ultraviolet B narrow band (UVB-NB) phototherapy is the gold standard treatment for vitiligo, primarily due to its immunomodulatory effects. Additionally, it may influence circadian melatonin balance, that may indirectly induce sleep regulation, which in turn could potentially contribute to vitiligo improvement. The association between melatonin, vitiligo and phototherapy has been little investigated. The aim of this study was to evaluate the current evidence regarding the effects of circadian melatonin regulation and sleep, particularly during vitiligo treatment with phototherapy. We undertook a narrative review to synthetize the evidence on this association through the MEDLINE/PubMed database, using combined search terms: melatonin, vitiligo, phototherapy, and circadian rhythm (sleep). A total of 56 articles were included. There are few studies on this relationship, and conflicting findings. Some studies have suggested that UV exposure and phototherapy might benefit vitiligo by stimulating melanocytes, which have melatonin receptors, and this could potentially synchronize the circadian regulation of melatonin. This improved melatonin balance could result in better sleep quality further enhancing the antiinflammatory properties of melatonin and contributing to vitiligo improvement. Less is known about the possible effects of the use of topical melatonin, with or without phototherapy, to treat vitiligo lesions. In conclusion, there is some evidence that circadian melatonin regulation plays an important role in the course of vitiligo, both through sleep regulation and its anti-inflammatory properties. The evidence suggests that the systemic and physiological properties of melatonin, especially its circadian behavior regulated by phototherapy, may be more effective in respect of vitiligo improvement than the use of topical melatonin. However, the effects of the oral intake of melatonin are less clear. Phototherapy, as a potential modulator of circadian melatonin rhythm, that influences sleep and clinical improvement of vitiligo, needs further examination, as does the use of melatonin as an adjuvant treatment to UVB phototherapy in vitiligo.

RESUMO

INTRODUCTION: Vitiligo is a prevalent skin disorder characterized by the destruction of melanocytes, leading to depigmented patches across various areas of the body. Interleukin (IL)-31 has been implicated in the development of pruritus and skin inflammation, potentially contributing to cutaneous symptoms. This study measures IL-31 levels in vitiligo patients with and without pruritus, comparing them to healthy controls, and explores the relationship between IL-31 levels, disease activity, and other clinical factors to assess its potential role in the early diagnosis of vitiligo. METHODS: Ninety individuals were enrolled in the study and equally divided into three groups: vitiligo, vitiligo with pruritus, and healthy controls. The serum level of IL-31 was measured using the enzyme-linked immunosorbent assay (ELISA). RESULTS: Significant differences in IL-31 levels were observed across all groups. IL-31 levels were highest in vitiligo patients with pruritus, followed by those without pruritus, and lowest in healthy controls, with mean values and standard deviations of 196 ± 67.28, 152.10 ± 74.39, and 80.03 ± 32.30 pg/ml, respectively. In addition, IL-31 levels in serum showed significant differences in relation to disease activity in both vitiligo groups. Positive correlations were found between IL-31 levels and the Vitiligo Area Scoring Index (VASI) and Vitiligo Disease Activity (VIDA) in both patient groups, as well as between IL-31 levels and lesion extent in vitiligo patients without pruritus. In patients with pruritus, IL-31 levels also positively correlated with age and the 5-dimension itch scale score. CONCLUSION: IL-31 may serve as a crucial marker and play a significant role in the early diagnosis of vitiligo in patients both with and without pruritus.

RESUMO

Vitiligo is an acquired chronic loss of skin pigmentation characterized by white and frequent symmetric patches, for which corticosteroids are the mainstay of treatment. Regular intake of steroids for prolonged periods is frequently associated with severe and sometimes irreversible adverse events. This study was designed to compare the effectiveness and safety profiles of azathioprine versus psoralen+ultraviolet light A (PUVA)-solar light (SOL; sunlight) to determine which agent reduces the length and adverse effects of vitiligo therapy in a better manner. This single-center, randomized, open-label, prospective case-control study recruited 100 patients. Oral mini-pulse (OMP) corticosteroid therapy was administered to all patients during the first month of the study. The first group of patients (group A) continued with azathioprine 50-mg tablet twice a day (BID), and the second group (group B) was given PUVA-SOL for 2 months with concurrent OMP. Disease activity was monitored. At the end of the study period, 58% (group A) and 50% (group B) of patients had their improved vitiligo area severity index (VASI) scores by 25%-50%. Similarly, 36% (group A) and 50% (group B) of patients improved their VASI score by more than 50%. On the global physician assessment scale, 42% (group A) and 54% (group B) patients had a good to excellent response. Based on these findings, both azathioprine and PUVA-SOL were considered as good steroid-sparing agents, primarily if used with an initial phase of concomitant oral corticosteroids.

RESUMO

While vitiligo is primarily caused by melanocyte deficiency or dysfunction, recent studies have revealed a notable prevalence of metabolic syndrome (MetS) among patients with vitiligo. This suggests shared pathogenic features between the two conditions. Individuals with vitiligo often exhibit variations in triglyceride levels, cholesterol, and blood pressure, which are also affected in MetS. Given the similarities in their underlying mechanisms, genetic factors, pro-inflammatory signalling pathways, and increased oxidative stress, this study aims to highlight the common traits between vitiligo and metabolic systemic disorders. Serum analyses confirmed increased low-density lipoprotein (LDL) levels in patients with vitiligo, compared to physiological values. In addition, we reported significant decreases in folate and vitamin D (Vit D) levels. Oxidative stress is one of the underlying causes of the development of metabolic syndromes and is related to the advancement of skin diseases. This study found high levels of inflammatory cytokines, such as interleukin-6 (IL-6) and chemokine 10 (CXCL10), which are markers of inflammation and disease progression. The accumulation of insulin growth factor binding proteins 5 (IGFBP5) and advanced glycation end products (AGEs) entailed in atherosclerosis and diabetes onset, respectively, were also disclosed in vitiligo. In addition, the blood-associated activity of the antioxidant enzymes catalase (Cat) and superoxide dismutase (SOD) was impaired. Moreover, the plasma fatty acid (FAs) profile analysis showed an alteration in composition and specific estimated activities of FAs biosynthetic enzymes resembling MetS development, resulting in an imbalance towards pro-inflammatory n6-series FAs. These results revealed a systemic metabolic alteration in vitiligo patients that could be considered a new target for developing a more effective therapeutic approach.

RESUMO

Vitiligo is an acquired autoimmune skin disease characterized by patchy depigmentation of the skin, often accompanied by white hair. The aetiology of vitiligo is complex and difficult to cure, and its disfiguring appearance significantly impacts patients' mental and physical health. Psychological stress is a major factor in inducing and exacerbating vitiligo, as well as affecting its treatment efficacy, though the specific mechanisms remain unclear. Increasing research on the brain-skin axis in skin immunity suggests that psychological stress can influence local skin immunity through this axis, which may play a crucial role in the pathogenesis of vitiligo. This review focuses on the role of brain-skin axis in the pathogenesis of vitiligo, and explores the possible mechanism of brain-skin axis mediating the pathogenesis of vitiligo from the aspects of sympathetic nervous system, hypothalamic-pituitary-adrenal (HPA) axis and hormones and neuropeptides, aiming to provide the necessary theoretical basis for psychological intervention in the prevention and treatment of vitiligo.

RESUMO

The progression of vitiligo is unpredictable, emphasizing the need to identify periods of activity early for tailored treatment. Confetti-like depigmentation, hypochromic areas/borders and Koebner's phenomenon are clinical visible signs associated with disease activity in vitiligo. However, their true clinical significance requires further investigation using standardized scoring systems. In the present study, the Vitiligo Signs of Activity Score (VSAS) and the Vitiligo Disease Activity Score (VDAS) were applied to assess disease activity signs and disease progression over time, respectively. Individuals with at least one disease activity sign had a 76.9% likelihood of having active vitiligo. The simultaneous presence of multiple signs or their appearance across body locations increased the likelihood to 94% and 87.1%, respectively. Patients with no disease activity signs had a 60.3% likelihood of having stable disease. This research provides an important nuance about the disease activity signs in vitiligo, which may help guide disease management. The risk of active disease increases when at least two types of vitiligo activity signs are present, or when they are present on different body locations. However, the absence of vitiligo activity signs does not rule out active vitiligo.

RESUMO

The use of medications which target the JAK-STAT signaling pathway, also known as janus kinase (JAK) inhibitors, has rapidly increased in recent years. Patient perceptions, opinions, and concerns regarding the use of JAK inhibitors are largely uninvestigated. Our objective is to better understand patient concerns, reported side effects, and sentiments regarding the use of JAK inhibitors for dermatologic disease. The authors performed a cross-sectional analysis of the most frequented subreddits for dermatologic disease in which JAK inhibitors have obtained FDA approval (r/atopic dermatitis, r/psoriasis, r/alopecia areata, r/vitiligo, and r/eczeJAKS). The sentiment, central theme, and engagement level of each post was evaluated using previously utilized methods. Nine hundred twenty-three posts were analyzed, with the majority focusing on efficacy (433, 47%) and medication-related side effects (150, 16%). Other themes of interest to patients were Payment/Insurance (84, 9%), Study Results/News (69, 7%), Administration/Dosage (33, 4%), and Medication Interactions (31, 3%). The most frequently reported side effects were acne/folliculitis (24, 22%), nausea/gastrointestinal disturbance (11,10%), and fatigue/muscle aches (10, 9%). At the same time, the medication interactions garnering the most concern were sunscreens/facial moisturizers (5, 16%), topical calcineurin inhibitors (4, 13%), and Marijuana/THC (3, 9.%). This analysis highlights that patients are most concerned about the efficacy and side effects of JAK inhibitors in addition to issues regarding access to JAK inhibitors. Providers can use the insights gained from this study to address hesitancy better and guide comprehensive, patient-centered discussions with patients regarding JAK inhibitor use.

RESUMO

Vitiligo is a significant dermatological challenge affecting 0.5 to 2% of the global population. Despite the various existing medical approaches, current vitiligo treatments are far from ideal. The present study aimed to prepare and evaluate a film-forming gel of 5 fluorouracil (5FU) using different ratios of hydroxypropyl methylcellulose (HPMC) and Zein for treating vitiligo. The prepared film-forming gels were fully characterized in terms of morphology, Fourier-transform infrared spectroscopy, drug content, pH, drying time, in-vitro drug release, and clinical investigation. A 32-full factorial design was used to study the impact of varying concentrations of HPMC (X1) and Zein (X2) on the percentage of 5FU released (Y1) from the prepared film-forming gels. Scanning electron microscopy (SEM) revealed a cross-linked network structure between polymers. An increase in HPMC concentration (2-4%) correlated with higher 5FU release, whereas increased Zein concentration (1-2%) resulted in reduced 5FU release. Furthermore, patients treated with 5FU film-forming gel after dermabrasion with fractional CO2 (FCO2) laser exhibited a significant decrease in JAK3 gene expression and higher effectiveness than those treated with FCO2 laser alone. Our results suggest that the film-forming gel of 5FU is promising as an effective formulation for treating vitiligo.

RESUMO

BACKGROUND: The specific role of oxidative stress (OS) in vitiligo and alopecia areata (AA) remains unclear. The aim of this study was to analyze and identify the key markers of OS in vitiligo and AA by bioinformatics. METHODS: We obtained vitiligo and AA datasets from gene expression omnibus (GEO) database. The difference-expressed genes of vitiligo and AA were identified by differential analysis, and the functions of difference-expressed genes were identified by gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Set Enrichment Analysis (GSEA) enrichment analysis. Subsequently, Veen package was used to obtain the intersection genes of OS-related genes with vitiligo and AA. Finally, we used CIBERSORT to assess the infiltration of immune cells in vitiligo and AA. RESULTS: Through enrichment analysis, we found that vitiligo and AA were mainly enriched in cell cycle and cell adhesion molecular channels. We identified KLB and EIF3C as key genes in OS regulation of vitiligo and AA, and found that KLB and EIF3C participate in disease progression by regulating T cells and neutrophils. CONCLUSIONS: According to our findings, KLB and EIF3C play a crucial role in the progression and development of vitiligo and AA, which have been identified as biomarkers and target for early diagnosis of patients.

RESUMO

BACKGROUND: Sirtuin 7 (SIRT7) is pivotal in diverse diseases progression. Importantly, SIRT7 is associated with melanin production. However, whether SIRT7 regulates vitiligo is unclear. Therefore, we aimed to investigate the effects of SIRT7 on pigmentation and the modification of glucose 6-phosphate dehydrogenase (G6PD). METHODS: After knockdown SIRT7 and G6PD, pigmentation of melanocytes was evaluated using commercial kits, immunofluorescence, and Western blot analysis. The succinylation of G6PD mediated by SIRT7 was analyzed using co-immunoprecipitation, immunofluorescence, Western blot analysis, and cycloheximide-chase experiment. RESULTS: We found that SIRT7 was highly expressed in vitiligo skin lesions. Knockdown of SIRT7 increased tyrosinase activity, melanin content, and the levels of α-melanocyte-stimulating hormone, MITF, TYR, TRP1, and TRP2. Additionally, SIRT7 directly interacted with G6PD. Silenced SIRT7 promoted the succinylation of G6PD and enhanced its protein stability. G6PD knockdown reversed the effect of reduced SIRT7 expression on melanin production. CONCLSUION: Silencing of SIRT7 promotes pigmentation of melanocytes by succinylating G6PD, suggesting that SIRT7-mediated G6PD desuccinylation may promote vitiligo progression.
