repigmentation

Post-burn leucoderma patients remain the most challenging to treat because they have two distinct issues: textural changes and hypopigmentation that must be managed simultaneously. A variety of surgical techniques have been used with variable outcome. This prospective study evaluated the efficacy of superficial dermabrasion followed by suction blister epidermal grafting (SBEG) in post-burn leucoderma treatment. Twenty patients, 15 females and 5 males, ages ranging from 18 to 52 years, all having post-burn leucoderma ranging from 10 to 36 months, were included...

Vitiligo belongs to a frequent chronic autoimmune skin disease with the features of pigmented plaques on the diseased skin along with potential damage of melanocytes. There are many factors underlying the pathogenesis of vitiligo, among which oxidative stress is extensively regarded to be the critical factor leading to the loss of melanocytes. The changed redox state resulting from oxidative stress, containing ROS overproduction along with the reduced activity of the skin's antioxidant system, makes melanocytes less resistant to exogenous or endogenous stimuli, and ultimately pushes normal defense mechanisms, resulting in the loss of melanocytes...

BACKGROUND: Vitiligo is a disease that affects people of all skin shades and can impact their quality of life. Reliable evidence on the effectiveness and adverse events associated with the recent use of Janus kinase (JAK) inhibitors to treat vitiligo is needed. This protocol for a systematic review and meta-analysis seeks to collect evidence from both randomized controlled trials (RCTs) and observational studies to determine the effectiveness and patient-centered outcomes concerning treatment with JAK inhibitors...

BACKGROUND: Vitiligo is characterized by depigmented patches resulting from loss of melanocytes. Phototherapy has emerged as a prominent treatment option for vitiligo, utilizing various light modalities to induce disease stability and repigmentation. AIMS AND METHODS: This narrative review aims to explore the clinical applications and molecular mechanisms of phototherapy in vitiligo. RESULTS AND DISCUSSION: The review evaluates existing literature on phototherapy for vitiligo, analyzing studies on hospital-based and home-based phototherapy, as well as outcomes related to stabilization and repigmentation...

Hypopigmented scars are challenging to treat, and the focus for successful treatment is to cause pigment cells to produce more melanin. In this study, we evaluated the repigmentation effects of 0.4 mm motorized-micropunch grafting with skin-seeding for hypopigmented scars. Twenty-one patients with hypopigmented scars on the face and neck that had been resistant to conventional treatment and who had finally undergone micropunch grafting with a skin-seeding technique (SST) were retrospectively reviewed...

Topical ruxolitinib 1.5% cream (Opzelura® ), a Janus kinase (JAK) inhibitor, is the first treatment to be approved in several countries for use in patients aged ≥ 12 years with non-segmental vitiligo. In the identical phase III TRuE-V1 and TRuE-V2 trials, significantly more ruxolitinib cream recipients were able to achieve statistically significant and clinically meaningful facial and total body repigmentation, as well as reductions in vitiligo noticeability, compared with vehicle recipients...

Vitiligo is a skin depigmentation disease resulting from melanocyte destruction and often co-occurring with autoimmune disorders like hyperthyroidism, alopecia areata, pernicious anemia, and systemic lupus erythematosus (SLE). Although various traditional treatments exist for vitiligo, their effectiveness varies considerably. This report presents a unique case of a vitiligo patient with concomitant systemic lupus erythematosus. Remarkably, after a 30-day course of treatment with tofacitinib, complete repigmentation of the white macular rash was achieved, and there were no adverse drug reactions...

BACKGROUND: Surgical intervention is the main therapy for refractory vitiligo. We developed a modified autologous cultured epithelial grafting (ACEG) technique for vitiligo treatment. Between January 2015 and June 2019, a total of 726 patients with vitiligo underwent ACEG in China, with patient characteristics and clinical factors being meticulously documented. Using a generalized linear mixed model, we were able to assess the association between these characteristics and the repigmentation rate...

BACKGROUND: Limited research exists on laser treatment of giant congenital melanocytic nevus (GCMN). OBJECTIVE: We sought to elucidate the efficacy of the Erbium: YAG laser on GCMN and the histologic factors associated with a positive clinical response. METHODS AND MATERIALS: Between 2019 and 2022, we enrolled 30 medium-to-giant CMN patients who underwent Er: YAG laser treatment. All patients received biopsies before and after laser treatments...

BACKGROUND: There is a strong correlation between alopecia areata (AA) and the development of white hair. The AA presents itself in many clinical manifestations of depigmented hair as the condition advances. It is uncommon for unpigmented hair to extensively regrow for more than one hair growth cycle in AA and successful conversion to pigmented hair after treatment has not yet been reported. AIM: We report two case studies involving the persistent regrowth of white hair after AA that became pigmented through treatment...

BACKGROUND: Suction blister epidermal grafting (SBEG) is currently one of the most prevalent surgical methods for stable vitiligo. OBJECTIVE: To investigate the long-term outcomes of vitiligo patients who underwent SBEG and to explore risk factors associated with postoperative relapse. METHODS: A retrospective cohort study was conducted in patients who underwent SBEG in our department between January 2016 and December 2022. Treatment outcomes, including repigmentation rate, adverse events, and postoperative relapse, were surveyed via telephone interview or out-=patient visit...

BACKGROUND: Narrowband ultraviolet B (NB-UVB) phototherapy promotes stability and repigmentation in vitiligo. No studies have compared targeted NB-UVB with whole-body NB-UVB in treatment of acral vitiligo. OBJECTIVES: This randomized split-body study compared whole-body NB-UVB with targeted NB-UVB in inducing stability and repigmentation in acral vitiligo. METHODS: Thirty-two patients with bilaterally symmetrical acral vitiligo lesions (distal to elbows and knees) were recruited...

INTRODUCTION: Vitiligo is a skin pigmentation disorder caused by the selective degradation of melanocytes. This study investigates the therapeutic effects of microneedling with and without N-acetylcysteine (NAC) in patients with persistent and limited vitiligo. METHOD: This research employed a clinical trial design with double-blind randomization. Individuals affected by vitiligo and seeking treatment at Rasool Akram Medical Complex were divided into two separate treatment groups...

BACKGROUND: Vitiligo, an autoimmune skin disorder linked to hormonal and genetic factors, results in reduced pigmentation due to a gradual decline in melanocyte activity. This systematic review delves into the role of dietary intervention and nutrition in managing vitiligo. METHODS: A comprehensive search on PubMed, Google Scholar, and European PMC identified 214 studies, with 14 meeting inclusion criteria post-screening. The selected studies primarily explored the impact of dietary supplements on disease activity...

Vitiligo, a psychologically distressing pigmentary disorder characterized by white depigmented patches due to melanocyte loss, necessitates non-invasive tools for early detection and treatment response monitoring. High-cellular-resolution full-field optical coherence tomography (CRFF-OCT) is emerging in pigmentary disorder assessment, but its applicability in vitiligo repigmentation after tissue grafting remains unexplored. To investigate the feasibility of CRFF-OCT for evaluating vitiligo lesions following tissue grafting, our investigation involved ten vitiligo patients who underwent suction blister epidermal grafting and laser ablation at a tertiary center between 2021 and 2022...

Vitiligo is a common, autoimmune, depigmenting disorder of the skin. Janus Kinase inhibitors have emerged as promising topical and oral therapeutic options for vitiligo. There have been no reports of vitiligo being treated with oral Abrocitinib, a selective Janus Kinase 1 inhibitor approved for the treatment of moderate to severe atopic dermatitis. Here, we present a 61-year-old male with acrofacial vitiligo who had repigmentation plateau with twice daily tacrolimus 0.1% ointment, oral ginkgo biloba, and oral minipulse prednisone × 4 months; however, they had significant improvement after taking abrocitinib 100 mg per day for 2 months...

Vitiligo is an acquired autoimmune dermatosis characterized by patchy skin depigmentation, causing significant psychological distress to the patients. Genetic susceptibility, environmental triggers, oxidative stress, and autoimmunity contribute to melanocyte destruction in vitiligo. Due to the diversity and complexity of pathogenesis, the combination of inhibiting melanocyte destruction and stimulating melanogenesis gives the best results in treating vitiligo. The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor that can regulate the expression of various downstream genes and play roles in cell differentiation, immune response, and physiological homeostasis maintenance...

Epimedin B (EB) is one of the main flavonoid ingredients present in Epimedium brevicornum Maxim., a traditional herb widely used in China. Our previous study showed that EB was a stronger inducer of melanogenesis and an activator of tyrosinase (TYR). However, the role of EB in melanogenesis and the mechanism underlying the regulation remain unclear. Herein, as an extension to our previous investigation, we provide comprehensive evidence of EB-induced pigmentation in vivo and in vitro and elucidate the melanogenesis mechanism by assessing its effects on the TYR family of proteins (TYRs) in terms of expression, activity, and stability...
