Vitiligo is an acquired cutaneous disorder that affects about 0.5%-2% of the global population. It is characterised by depigmented macules due to the loss of melanocytes. This condition may significantly affect the psychosocial and emotional well-being of patients, cause diminished self-esteem, and lead to social ostracization. Traditional therapeutic options include topical treatments like corticosteroids and calcineurin inhibitors, as well as topical or systemic phototherapy. Systemic immunomodulators target immune and inflammatory pathways to halt depigmentation and bring about repigmentation. Recent insights into the pathogenesis of vitiligo indicate an interplay of genetic, autoimmune, and environmental factors, with oxidative stress and genetic predisposition playing a part as well. Novel treatment modalities targeting multiple molecular targets, such as the JAK-STAT pathway, melanocortin-1 receptor, and different immune checkpoints, aim to combat autoimmunity and enhance melanocyte function. These emerging therapies offer encouraging results, although literature on them is limited and efficacy varies among patients. The continuous advancement in treatment strategies, along with advances in genetic and pathophysiological research, underscores a dynamic and hopeful course for vitiligo management, which in turn can improve the quality of life of affected individuals.
白癜风是一种获得性皮肤病,影响全球约0.5%-2%的人口。其特征是由于黑素细胞丧失而出现色素脱失斑。这种情况可能会显著影响患者的心理社会和情感健康,导致自尊下降,并引发社会排斥。传统的治疗选择包括外用治疗,如皮质类固醇和钙调神经磷酸酶抑制剂,以及外用或系统光疗。全身免疫调节剂针对免疫和炎症途径来阻止色素脱失并实现色素再生。最近对白癜风发病机制的见解表明,遗传、自身免疫和环境因素相互作用,氧化应激和遗传易感性也起一定作用。针对多个分子靶点的新型治疗方式,如JAK-STAT途径、黑皮质素-1受体和不同的免疫检查点,旨在对抗自身免疫并增强黑素细胞功能。这些新兴疗法取得了令人鼓舞的结果,尽管相关文献有限,且疗效因患者而异。治疗策略的不断进步,以及遗传和病理生理学研究的进展,凸显了白癜风管理的动态且充满希望的进程,这反过来可以改善受影响个体的生活质量。
