Objective To determine the frequency of autoimmune disorders associated with alopecia areata in patients presenting in a tertiary care hospital.Methods This study was conducted at the Dermatology Department, Unit II, KEMU/Mayo Hospital, Lahore.120 patients fulfilling the inclusion criteria were entered in the study during May 2013 to January 2014. After taking informed consent and recording demographic data, complete history was taken. Examination was performed and investigations were carried out where needed, for determination of factors associated with alopecia areata. Results Out of 120 patients studied, 30.8% of patients had positive family history of alopecia areata. Atopic dermatitis was found in 29.2% of patients. Vitiligo and hypothyroidism were seen in 4.2% each. Diabetes mellitus was seen in 1.7% of the cases and 0.8% were hyperthyroid. Conclusion Postive family history and atopic dermatitis were seen in one third of our patients with alopecia areata. Vitiligo and hypothyroidism were other important associations observed.References
