Abstract:
BACKGROUND: Vitiligo is riot quite a rare diseasep; it has about 1% prevalence. The cause of vitiligo is not clear, however, in recent studies an autoimmune origin is freqluei itily mentioned. OBJECT: We tried to an lyze some clinical features of vitiligo and relate them with the presence of autoantibodies. MEHTODS: A total of 381 vitiligo patients was included for the analysis of clinical features. A laboratory study included rhumatoid factor, antinuclear antibocoly, antithyroglobulin antibody and antimicrosome antibody. Some 62 patients were examined for opl thmologic changes. RESULTS: One hundred and one(26.5%) of 381 patients exam ned showed at least one of the autoantibodies tested. Twenty nine pateints showed 2 different aitintibodies. The age at aonset of vitiligo in the autoantibody positive group was 6.6 years later than that of the autoantibody negative group. Autoimmune and/or endocrine diseases were more frequinty found among aut.oantibody positive patients. These diseas s included hyperthyroidism, diabetes me litus and alopecia areata. One patient revealed retinal hypoigmentation and showed no autoantibcidics. CONCLUSION: About 9% of vitiligo patients who were autoantiocyte positive had clinical evidence of diseases associated with the autoantibody. However, it is prudent. to xpect that more patients with t.he autoantibody may develop later systemic autoimmune diseases or endocrinopathies. A long term follow-up of these patients seem:, to be very important.
