Isolated IgG4-Related Tubulointerstitial Nephritis with Rapid Progression Requiring Hemodialysis (KIDNEY WEEK 2026) - Oct 2, 2026 - Abstract #TH-PO0724; Pres time: Oct 22, 2026; 10:00 AM - 12:00 PM; Location: Exhibit Hall A, Convention Center; "The patient was treated with high-dose prednisone followed by rituximab therapy with subsequent improvement in renal function. Early recognition of IgG4-related kidney disease is critical, as timely immunosuppressive therapy may allow for meaningful renal recovery even after dialysis initiation. Renal biopsy demonstrating 25% global glomerulosclerosis (14/56 glomeruli; expected ≤7% for age) with severe tubulointerstitial fibrosis and tubular atrophy (60% of the renal parenchyma), consistent with IgG4-related tubulointerstitial nephritis."
