Description
Summary:The aim of the study was to compare the course of the disease and treatment outcomes in ANCA-positive and ANCA-negative eosinophilic granulomatosis with polyangiitis (EGPA) patients from one Polish tertiary referral centre. Retrospective and prospective cohort study carried out on 50 patients treated in our department between 1998 and 2012. EGPA diagnosis was based on the American College of Rheumatology (ACR) criteria. Treatment protocol was based primarily on the predictive Five Factor Score (FFS) scale. Clinical characteristics of the patients, general symptoms, organ involvement, treatment regimen, and follow-up outcomes were evaluated according to ANCA status. Fifteen ANCA-positive patients and 35 ANCA-negative patients were enrolled. At the time of diagnosis ANCA-positive patients had a higher incidence of renal involvement (53% vs. 7.7%; p
