ANTINEUTROPHIL CYTOPLASMIC ANTIBODY-ASSOCIATED VASCULITIS IN “REAL LIFE” – SERIES OF CLINICAL CASES IN A ROMANIAN REFERENCE CENTER

Introduction. Antineutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV) represent a group of conditions evolving with necrotizing inflammation in small and medium-sized blood vessels. AAV are composed of GPA (granulomatosis with polyangiitis, former Wegener’s granulomatosis), MPA (microscopic polyangiitis) and EGPA (eosinophilic granulomatosis with polyangiitis, former Churg-Strauss syndrome). AAV receive immunosuppressive therapy associated with a high risk of complications. Objective. The aim of this study was to characterize a single center cohort of AAV patients regarding clinical, biological and therapeutic features. Method. We realized a cross-sectional study by consequently enrolling all the patients registered with AAV diagnosis between 2009 and 2017 in Department of Rheumatology of “Sfânta Maria” Hospital. Demographic, diseaserelated and therapeutic-related parameters were collected. The data was extracted from the clinical files. Results. The study sample included 26 cases, 15 females and 11 males: 20 patients GPA, 4 MPA and 2 cases EGPA. Mean age at the time of diagnosis was around 48 but 12 patients presented delays between age at the onset and age at the t
