Histological and clinical predictors of early and late renal outcome in ANCA-associated vasculitis

These data suggest that in AASV, evaluation of renal histopathology is helpful in predicting early and late renal outcome. Chronicity and proteinuria were the best determinants of poor renal prognosis. Activity may regress under therapy, while chronicity may progress despite treatment. The amount of CYC seems to influence the occurrence of early relapses and renal survival.
