Enteric Infection-Associated Chronic Active Interstitial Nephritis and Collapsing Glomerulopathy in a Patient with a COL4A3 Variant (KIDNEY WEEK 2026) - Oct 2, 2026 - Abstract #FR-PO0721; Pres time: Oct 23, 2026; 10:00 AM - 12:00 PM; Location: Exhibit Hall A, Convention Center; "Patient was treated with pulse intravenous methylprednisolone 500mg daily for 3 days followed by prednisone taper over 6 weeks, and one dose of Rituximab 1gm, resulting in marked renal recovery. Genetic testing later identified a heterozygous COL4A3 variant, while APOL1 testing was negative. Discussion This case highlights a previously unreported association between enteric bacterial infection and concurrent CAIN and CG, supporting a potential infection-triggered inflammatory response and podocytopathy in a genetically susceptible host."
