J Pak Assoc Derma Jan ;31(4):583-7.

Objective: To determine the frequency of positive thyroid peroxidase antibodies in patients of generalized vitiligo.  Methods: This cross sectional study was conducted in the Dermatology Unit 1 of Jinnah Hospital, Lahore for a period of six months. 125 cases of generalized vitiligo, of both genders, ages between 15-60 years, and with any duration of disease were enrolled.  Results: A total of 125 cases of generalized vitiligo were enrolled. 61.6% (n=77) patients were between 15-30 years of age whereas 38.4 % (n=48) were between 31-60 years of age, Mean was calculated as 31.56±7.77 years, 56.8% (n=71) were male and 43.2% (n=54) were females. Frequency of positive thyroid peroxidase antibodies in patients of generalized vitiligo was recorded in 32.8% (n=41).  Conclusion: The frequency of positive thyroid peroxidase antibodies is significant in patients of generalized vitiligo.
