Researchers identify risk factors for poor prognosis in alopecia areata
Alopecia areata (AA) is a common autoimmune disease that leads to sudden circular hair loss. The clinical course of AA is unpredictable and varies greatly from individual to individual. Numerous studies have shown that AA is often associated with comorbid, i.e. co-existing, chronic inflammatory diseases, which can have an impact on prognosis and clinical management.
