What this trial studies

This observational study focuses on Eosinophilic Granulomatosis With Polyangiitis (EGPA), a rare immune disorder characterized by asthma, high eosinophil levels, and vasculitis. The study aims to identify new biological markers that can help assess disease activity and severity in patients with EGPA. Participants will undergo regular visits every six months or annually, during which blood and urine samples will be collected, and questionnaires will be administered to evaluate their health status and disease progression. The findings may enhance clinical care and inform future drug development for EGPA.
