Refractory Seropositive but Biopsy-Negative Anti-Nephrin Antibody-Associated Podocytopathy: A Case Report (KIDNEY WEEK 2026) - Oct 2, 2026 - Abstract #FR-PO0703; Pres time: Oct 23, 2026; 10:00 AM - 12:00 PM; Location: Exhibit Hall A, Convention Center; "High-dose corticosteroid therapy (prednisolone 40 mg) and rituximab (500 mg, three times) were administered, but failed to induce clinical remission. Subsequently, five sessions of LDL apheresis were performed, followed by combination therapy with cyclosporine and mycophenolate mofetil...However, similar observations are rarely reported in podocytopathy. This refractory case, characterized by seropositive but biopsy-negative anti-nephrin antibody, which also demonstrated FSGS lesions on repeat biopsy, may suggest a potentially severe disease phenotype in podocytopathy."
