Abstract
Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is a group of autoimmune disorders. It was previously assumed that the complement system is not involved in the development of ANCA-associated vasculitis due to its “pauci-immune” feature in renal histology. However, increasing evidence indicates that activation of the complement system, especially via the alternative complement pathway, plays a crucial role in the pathogenesis of ANCA-associated vasculitis. In this brief review, we discuss the evidence, including in vivo, in vitro, and clinical studies, for complement system activation in ANCA-associated vasculitis.
