This is an exciting phase of vitiligo research with the current understanding of vitiligo pathogenesis and its translation to successful treatment. The pathogenetic origin of vitiligo revolves around autoimmunity with supporting role from many other factors like oxidative stress, inherent melanocyte defects, or defective keratinocytes and fibroblasts. Vitiligo can be classified into segmental or non-segmental depending upon the clinical presentation, or it can be classified as progressing or stable based on the activity of the disease. Vitiligo treatments need to be stratified depending upon which type of vitiligo we are treating and at which phase the vitiligo patient presents to us. There are two different aims of treatment of vitiligo. The first involves rescuing the melanocytes from the damage to arrest the depigmentation. The second strategy focuses on replenishing the melanocytes so that successful repigmentation is achieved. It is also important to maintain the disease in a stable phase or prevent relapse. As stability in non-segmental vitiligo is a dynamic process, maintenance of the stability of repigmentation is also an important consideration in the management of vitiligo. In this review, we shall briefly discuss the current options and future insight into the management of vitiligo.
这是白癜风研究的一个令人兴奋的阶段,目前人们对白癜风的发病机制有了了解,并将其成功转化为治疗方法。白癜风的发病根源围绕着自身免疫,还有许多其他因素也起作用,如氧化应激、黑色素细胞固有缺陷、角质形成细胞和成纤维细胞功能缺陷等。根据临床表现,白癜风可以分为节段性或非节段性;根据疾病的活动程度,也可以分为进展期或稳定期。白癜风的治疗需要根据所治疗的白癜风类型和患者就诊时的疾病阶段进行分层。白癜风的治疗有两个不同的目的。第一个目的是挽救黑色素细胞免受损伤,以阻止色素脱失。第二个策略是补充黑色素细胞,从而实现成功复色。保持疾病处于稳定期或防止复发也很重要。由于非节段性白癜风的稳定性是一个动态过程,因此维持复色的稳定性也是白癜风治疗的一个重要考虑因素。在这篇综述中,我们将简要讨论白癜风治疗的现有选择和未来的见解。
