Clinical, Laboratory, and Therapeutic Analysis of Behçet's Disease in Assiut

Eligible participants are adults and adolescents diagnosed using international criteria (ISG and rICBD), with recurrent oral ulceration and at least two additional manifestations (genital ulcers, eye lesions, skin lesions, positive pathergy test). Patients with unconfirmed BD are excluded. Given BD's variable age and gender distribution, the population will reflect regional epidemiological trends, including a probable male predominance consistent with Arab and Mediterranean cohorts. Comprehensive sociodemographic data, disease duration, age at onset, family/personal history, and clinical presentation are documented. All patients are monitored through a structured two-year inclusion, maximizing sample heterogeneity and capturing real-world data from both inpatient and outpatient clinical pathways .
