Real-world Burden of Disease and Clinical Characteristics of Alopecia Areata Among Adults in Brazil: Results from a Cross-sectional Survey

This study surveyed 341 adult patients with alopecia areata (AA) in Brazil, revealing significant variations in disease severity and treatment patterns based on the extent of scalp hair loss (SHL) and healthcare access. Patients with more severe hair loss (≥ 50% SHL) experienced greater psychosocial impacts and were more likely to receive care in public health settings. The primary treatment goals are to reduce hair loss and improve quality of life, but access to advanced therapies like JAK inhibitors is limited, particularly in public systems. The study highlights the need for improved management strategies and policy interventions to enhance access to advanced treatments and address healthcare inequalities in Brazil.
