Primary Anti-C1q-Associated Renal Vasculitis: A Clinicopathologic Case Series (KIDNEY WEEK 2026) - Oct 2, 2026 - Abstract #FR-PO0641; Pres time: Oct 23, 2026; 10:00 AM - 12:00 PM; Location: Exhibit Hall A, Convention Center; "Induction therapy included: rituximab (n=2), rituximab plus cyclophosphamide (n=1) and cyclophosphamide alone (n=1). Only one patient experienced renal relapse 23 months after remission, requiring retreatment. Conclusion Primary anti-C1q-associated renal vasculitis may represent an underrecognized complement-mediated clinicopathologic spectrum characterized by severe renal involvement, heterogeneous renal pathology, and persistent anti-C1q positivity despite clinical response."
