İntroduction: Granulomatosis polyangitiis (GPA), eosinophilic granulomatosis with polyangiitis (EGPA and microscopic polyangiitis(MPA) are small vessel vasculitides associated with anti-neutrophil cytoplasmic antibody (ANCA). İn this study, the frequency of ANCA associated vasculitis and treatment responses in our clinic are evaluated. Methods: This retrospective study was performed between January 2015- December 2018. 18 patients who older than 18 and diagnosed ANCA associated vasculitis according to the 2012 Chapel Hill Classification were included. Results: İn totals, 18 patients who diagnosed ANCA associated vasculitis were included, 12 of whom females, 6 of whom males. The mean age of the patients was 57.8. Two of the patients were diagnosed with EGPA, 3 with MPA and 13 with GPA. 11 of the patients followed up with GPA with systemic involvement and 2 with limited involvement. The most common involvement in patients with GPA was pulmonary involvement with 76% and renal involvement in 53% of the patients. Pulmonary involvement was detected in 2 patients and lung involvement in 2 patients in MPA. Pulmonary involvement was observed in 2 patients with EGPA. RF and ANA positivity was highest in GPA. İt was observed in combination with pulse steroid and cyclophosphamide in the induction treatment of ANCA-associated vasculitis. It was seen that 3 GPA patients had recurrence and followed up with rituximab. Discussion-conclusion: ANCA related vasculitides treatment and clinic are similar. İn the treatment of ANCA-associated vasculitis, remission should be achieved in a short time. In recurrent cases, rituximab may be preferred.
