Objectives: Vitiligo is more common in people with certain autoimmune diseases. Here we studied the association between vitiligo and autoimmune diseases. Materials and Methods: In this case control study, 86 patients with vitiligo were questioned about the location of vitiligo, family history, treatment and therapeutic response. All patients were examined both clinically and with laboratory tests to detect the presence of autoimmune disorders including autoimmune thyroid disease, pernicious anemia, insulin dependent diabetes, systemic lupus erythematic (SLE) and Addison disease. The prevalence of autoimmune disorder in vitiligo patients with that in a group of age- and gender-matched normal population was compared. Results: Average age of disease onset was 21.8 + 11 years; 61% of patients were females and 39% were males. The most common locations of vitiligo were hands (33.7%) and face (32.1%). The most common pattern of onset was vulgaris type (40%). Nearly one-fourth of patients had a positive family history of vitiligo. Prevalence of thyroid disorders in vitiligo patients and control group was 21.1% and 7%, respectively. The difference was statistically significant (P=0.008). Conclusion: The most common autoimmune disorder in patient with vitiligo was hypothyroidism. Family history had a poor prognostic effect on response to therapy.
