Short-term efficacy and safety of upadacitinib combined with 308 excimer light versus upadacitinib alone and 308 excimer light alone in patients with progressing facial vitiligo.

Patients with progressing facial vitiligo who had been treated with upadacitinib, 308 nm excimer light and upadacitinib combined with 308 nm excimer light were selected for retrospective analysis and comparison of their efficacy and safety. Efficacy was evaluated using the Vitiligo Area Severity Index (VASI) and Dermatology Life Quality Index (DLQI) at baseline, after 8 weeks, and after 20 weeks. The progression of skin lesions was monitored through reflectance confocal microscopy (RCM), while adverse reactions were documented.

Background: Melanocytes protect the body from ultraviolet radiation by synthesizing melanin. Tyrosinase, a key enzyme in melanin production, accumulates in the endoplasmic reticulum (ER) during melanin synthesis, potentially causing ER stress. However, regulating ER function for melanin synthesis has been less studied than controlling Tyrosinase activity.

Vitiligo is an autoimmune disease that has been recognized, stigmatized, and treated for millennia. Recent translational research has revealed key mechanisms of disease, including cellular stress, innate immune activation, T cell-mediated elimination of melanocytes from the skin resulting in clinically apparent white spots, as well as stem cell regeneration that reverses established lesions. Many of these pathways have been targeted therapeutically, leading to the first FDA-approved medication to reverse the disease, with many more in clinical trials.

Few studies discuss the co-management of vitiligo and acquired hyperpigmentation disorders (AHD) such as melasma, erythema dyschromicum perstans, post-inflammatory hyperpigmentation, drug-induced hyperpigmentation, and lichen planus pigmentosus. This review discusses clinical studies examining co-management strategies and identifies current practice gaps. Dermatology Life Quality Index scores are higher in individuals with vitiligo or melasma.

Objective: To present and analyze eight clinical cases illustrating the use of rose stem cell-derived exosomes (RSCEs) in treating various dermatological conditions and to review current literature on plant-derived exosomes in medicine and dermatology.
Background: RSCEs possess low cytotoxicity, high biocompatibility, and effective cellular uptake, making them promising agents for dermatological therapies. A literature review included in the introduction and discussion covers the broader role of plant-derived exosomes, highlighting their therapeutic potential in skin treatment.
