Frequency of Autoimmune Disorders in Patients of Alopecia Areata: A Cross-Sectional Survey

This study investigated the prevalence of autoimmune disorders in 200 patients with alopecia areata, aged 18 to 65. It found that 25% of these patients had an autoimmune disorder, with hypothyroidism being the most common, affecting 15% of participants. Other identified conditions included vitiligo (5.5%), systemic lupus erythematosus (2.5%), hyperthyroidism (2%), and psoriasis (1.5%). The study highlights the significant association between alopecia areata and autoimmune disorders, emphasizing the need for screening, particularly for thyroid-related conditions, in patients with alopecia areata.
