Clinical Characteristics and HLA Alleles of a Family With Simultaneously Occurring Alopecia Areata

In our patients, psychiatric evaluations revealed obsessive-compulsive personality disorder in patients 2 and 3, depression in patient 3, and symptoms of anxiety with a lack of self-confidence in patients 1 and 4. Psychiatric disorders affecting the entire family may stem from unemployment of the father. Similar to the results noted in prior studies, depression, the most commonly associated psychiatric disorder of AA, was present in 2 of 4 patients. Obsessive-compulsive disorder, the second most common psychiatric disorder among AA patients, was present in patients 2 and 3. These results indicate that AA may be associated with shared stressful events and psychiatric disorders. Therefore, in addition to dermatologic treatment, it was recommended that all patients undergo psychiatric treatment and follow-up regularly with a psychiatrist; however, the patients declined. At the end of a 1-year treatment period and follow-up, resistance to therapy with minimal recovery followed by a rapid recurrence was determined in patients 1 and 2.

Conclusion

This report demonstrated that familial AA was strongly associated with psychological disorders that were detected in all patients. In our patients, HLA alleles did not seem to have a role in the development of familial AA. These results suggest that HLA was not associated with AA triggered by psychological stress. We believe that psychological disorders and stressful life events may play an important role in the occurrence of AA and lead to the development of resistance against treatment in familial and resistant AA cases.
