Vitiligo is a relatively common acquired pigmentation disorder that can cause significant psychological stress and stigmatism.
This article aims to familiarize physicians with the clinical manifestations, evaluation, diagnosis, and management of vitiligo.
A Pubmed search was conducted in Clinical Queries using the key term "vitiligo". The search included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. The search was restricted to English language. The information retrieved from the above search was used in the compilation of the present article.
Approximately one quarter of patients with vitiligo have the onset before 10 years of age. Genetic, immunological, neurogenic and environmental factors may have a role to play in the pathogenesis. Vitiligo typically presents as acquired depigmented, well-demarcated macules/patches that appear milk- or chalk-white in color. Lesions tend to increase in number and enlarge centrifugally in size with time. Sites of predilection include the face, followed by the neck, lower limbs, trunk, and upper limbs. The clinical course is generally unpredictable. In children with fair skin, no active treatment is usually necessary other than the use of sunscreens and camouflage cosmetics. If treatment is preferred for cosmesis, topical corticosteroids, topical calcineurin inhibitors, and narrowband ultraviolet B phototherapy are the mainstays of treatment.
The therapeutic effect of all the treatment modalities varies considerably from individual to individual. As such, treatment must be individualized. In general, the best treatment response is seen in younger patients, recent disease onset, darker skin types, and head and neck lesions. Topical corticosteroids and calcineurin inhibitors are the treatment choice for those with localized disease. Topical calcineurin inhibitors are generally preferred for lesions on genitalia, intertriginous areas, face, and neck. Narrowband ultraviolet B phototherapy should be considered in patients who have widespread vitiligo or those with localized vitiligo associated with a significant impact on the quality of life who do not respond to treatment with topical corticosteroids and calcineurin inhibitors.
白癜风是一种较为常见的获得性色素沉着障碍性疾病,可导致明显的心理压力和耻辱感。
本文旨在使医生熟悉白癜风的临床表现、评估、诊断和治疗。
使用关键词“vitiligo”在 Clinical Queries 中进行 Pubmed 搜索。搜索包括荟萃分析、随机对照试验、临床试验、观察性研究和综述。搜索仅限于英语。从上述搜索中检索到的信息用于编写本文。
大约四分之一的白癜风患者在 10 岁之前发病。遗传、免疫、神经和环境因素可能在发病机制中起作用。白癜风通常表现为获得性色素脱失、界限清楚的斑疹/斑块,颜色呈牛奶色或粉笔白色。皮损数量增多,随时间离心性扩大。好发部位包括面部,其次是颈部、下肢、躯干和上肢。临床过程通常不可预测。对于皮肤白皙的儿童,通常不需要积极治疗,除了使用防晒霜和伪装化妆品外。如果出于美容目的需要治疗,则主要治疗方法为外用皮质类固醇、外用钙调神经磷酸酶抑制剂和窄谱中波紫外线光疗。
所有治疗方法的治疗效果因人而异,差异很大。因此,必须个体化治疗。一般来说,最佳治疗反应见于年轻患者、疾病早期发病、深色皮肤类型和头颈部病变。局部疾病的治疗选择是外用皮质类固醇和钙调神经磷酸酶抑制剂。外用钙调神经磷酸酶抑制剂通常用于生殖器、皱褶部位、面部和颈部的病变。对于广泛的白癜风或局部白癜风伴有明显影响生活质量且对外用皮质类固醇和钙调神经磷酸酶抑制剂治疗无反应的患者,应考虑窄谱中波紫外线光疗。
