Objective To investigate the prognosis predictors of anti-neutrophil cytoplasmic antibody(ANCA)-associated glomerulonephritis treated with glucocorticoid(GC).Methods The clinicopathological data of patients with biopsy-confirmed ANCA-associated glomerulonephritis were retrospective analyzed by retrieving the medical database in Peking Union Medical College Hospital from January 2000 to May 2015. Pathological categories were re-classified. Renal remission rates,infection rates,and death events were compared between intravenous glucocorticoid(GC)pulse therapy group and non-pulse group. Logistic regression analysis was performed to analyze factors influencing the short-term prognosis.Results Among the 81 patients with ANCA-associated glomerulonephritis,49(60.5%)received GC pulse therapy and 32(39.5%)did not. The GC pulse group had significantly lower estimated glomerular filtration rate at baseline(eGFR0)than the non-pulse group(t=3.003,P=0.015)but significantly higher 24-hour urinary protein(24 hUP)(t=2.394,P=0
