<h3>Background:</h3> Until now, prospective long-term observational data on the disease course of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) were missing in Germany. Therefore, the Joint Vasculitis Registry in German-speaking countries (GeVas) has been established to follow the course of patients with AAV. <h3>Objectives:</h3> To present baseline data of patients with newly diagnosed and relapsing AAV enrolled in the GeVas registry. <h3>Methods:</h3> GeVas is a prospective, web-based, multicenter, clinician-driven registry for the documentation of organ manifestations, damage, long-term outcomes, and therapy regimens in various types of vasculitis [1]. Recruitment started in June 2019 and is currently being conducted by 15 centers in Germany to date. <h3>Results:</h3> Between June 2019 and October 2022, 266 patients with AAV were included in the GeVas registry, hereof 173 (65%) with new-onset and 93 (35%) with relapsing AAV. One hundred and sixty-two (61%) patients were classified as granulomatosis with polyangiitis (GPA), 68 (26%) as microscopic polyangiitis (MPA), and 36 (14%) as eosinophilic granulomatosis with polyangiitis (EGPA). The median age was 59 years (51-70 years, IQR), 130 (51%) patients were female, 136 (49%) males. Most patients were ANCA positive (177; 67%) and affected by general symptoms, pulmonary, ear nose throat (ENT), renal and neurological involvement. For induction of remission, the majority of patients received glucocorticoids (247, 93%) in combination with either rituximab (118, 45%) or cyclophosphamide (112, 42%) (Table 1). <h3>Conclusion:</h3> Herein, we present baseline data from an inception cohort of AAV patients in the GeVas registry. Demographic characteristics are largely comparable to those in other European countries. Hoewever, differences were found regarding ANCA-status, frequencies of organ manifestations, and therapeutic regimen [2-4]. The GeVas registry will allow continued longitudinal observation and prospective outcome measures in AAV. <h3>REFERENCES:</h3> [1] Iking-Konert C, et al.
