associated with a lot of other autoimmune disorders. Aim of the study was to determine the prevalence of other co- morbid
autoimmune disorders in vitiligo patients in our Institution. Methods: A total of 100 patients with vitiligo who attended our
Hospital vitiligo clinic were included. Patients with lesion which were less than 1cm in size and inactive vitiligo were
excluded from the study. The co- morbid autoimmune disorders were collected and analyzed. Results: In our study group
of 100 patients with vitiligo, 30 patients had autoimmune disorders. Out of the 30 patients, 20 patients had Diabetes
Mellitus and it was found out to be the most common autoimmune disorder. Among the rest of 10 patients, 5 patients had
pernicious anemia, 2 patients had alopecia areata, 2 patients had psoriasis vulgaris and 1 patient had linear morphea.
Conclusion: Most of the patients with vitiligo have one or more autoimmune disorder which supports the autoimmune
theory of vitiligo. It therefore mandatory to screen all patients of vitiligo for autoimmune disorders.
