Idiopathic Membranous Nephropathy (IMN) Overview

Idiopathic Membranous Nephropathy (IMN) is a primary, autoimmune-mediated glomerular disease that stands as a leading cause of nephrotic syndrome in non-diabetic adults. Clinically, it is characterized by massive proteinuria (>3.5 g/day), profound peripheral edema, hypoalbuminemia, hyperlipidemia, and a notably high risk of thromboembolic events, particularly renal vein thrombosis. The underlying pathophysiology involves the subepithelial deposition of IgG4 and complement complexes on the glomerular basement membrane, which triggers podocyte injury and filtration barrier failure. In modern 2026 nephrology, the term “idiopathic” is rapidly being replaced by antigen-specific classifications, as approximately 70–80% of these cases are now known to be driven by circulating autoantibodies against the M-type phospholipase A2 receptor (PLA2R), with another 1–5% targeting THSD7A. Diagnosis relies on serological testing for these biomarkers alongside a renal biopsy demonstrating a classic “spike and dome” morphological pattern. Management is highly risk-stratified, pairing conservative antiproteinuric therapies (such as RAAS blockade) with targeted immunosuppression—most frequently B-cell depleting agents like rituximab—to induce immunological remission and preserve renal function.
