Background: Alopecia areata (AA) is a common cause of noncicatricial alopecia that occurs as a patchy, confluent or diffuse pattern. Exact etiologic factor of AA not yet recognized. Among many hypothesis, relationship between AA and autoimmune disease, especially thyroid disorders, was more interesting. The objective of this study was to determine the prevalence of thyroid test disorders in the patients with alopecia totalis and universalis in comparison with normal population.
Methods: We analyzed medical records of 100 patients, including 44 male and 56 female in Tehran Razi Hospital from 1388 to 1389. The mean age was 24.1 years. Patients having totalis and universalis form of AA considered as case group while 100 normal person (42 male and 58 female with mean age of 26.1) who had not any form of AA considered as control group. Both groups had not any sign of thyroid disease at clinical examination according to their available medical records. Collected data were analyzed statistically in SPSS software 17th version.
Results: In the majority of patients (54%) the disease was manifested in the first two decades of life. History of atopia was seen in 9.8% of patient. Presence of the similar disease in first-degree family members was seen in 14.3% of patients. Abnormal T3, T4 and TSH were significantly higher in case group. Abnormal T3 uptake was higher in case group but not statistically significant.
Conclusion: Paraclinical thyroid disorders were significantly higher in the alopecia areata patients than in normal population. There was no significant association between the age, sex and duration of disease and presence thyroid dysfunction.
