Abstract:

Atypical hemolytic uremic syndrome (aHUS) and C3 glomerulopathy (C3G) are well-recognized complement-mediated kidney diseases. In recent years, an increasing body of evidence has demonstrated that the complement system plays a pivotal role in the pathogenesis of various immune-mediated kidney diseases, such as IgA nephropathy, membranous nephropathy (MN), lupus nephritis (LN), antineutrophil cytoplasmic antibody-associated vasculitis (AAV), and anti-glomerular basement membrane disease (anti-GBM disease). Although current immunosuppressive therapies and corticosteroids can partly control disease progression, these agents are frequently associated with severe adverse effects, and a portion of patients show suboptimal therapeutic responses. Therefore, the development of novel therapeutic strategies is an urgent necessity. Complement-targeted therapies have emerged as a research focus, providing new avenues for the treatment of immune-mediated kidney diseases. This review summarizes recent advancements in this field.
