Long-term outcome of severe alveolar haemorrhage in ANCA-associated vasculitis: a retrospective cohort study

Abstract

Severe AH was more commonly associated with PR3-ANCA (vs. MPO-ANCA) and strongly correlated with renal vasculitis. Current treatment of severe AH leads to remission but long-term mortality remains high. Concurrent renal failure and older age were associated with higher mortality.
