New ‘Antigens’ in Membranous Nephropathy

Membranous Nephropathy

A forty-three year old female applied for a $200,000 ten year decreasing term policy. She admitted a history of "kidney disorder" on the application. She was not being treated or having any symptoms but stated that she was under observation. A routine paramed exam showed height 5’4", weight 140 lbs, and blood pressure 110/70. The BCP was normal. The HOS showed 210 mg/dl proteinuria. A reflex de...

Membranous Nephropathy

Forty-one patients with a nephrotic syndrome and biopsy-proven membranous nephropathy were administered a 3 to 6-month course of cyclosporine (CsA; 4 to 5 mg/kg per day). Differential solute clearances were used to evaluate glomerular function before and after therapy. CsA lowered median proteinuria by 56%, from 7.3 to 3.2 g/24 h (P < 0.0001). Corresponding mean increments in serum albumin, imm...

Membranous Nephropathy

Membranous nephropathy (MN), a very common cause of nephrotic syndrome, is a glomerulopathy defined histopathologically by the presence of immune complexes on the extracapillary side of the glomerular basement membrane (GBM). Idiopathic membranous nephropathy (IMN) is an antibody-mediated glomerular disease with no defined etiology, histologically characterized by uniform thickening of glomerul...

Membranous nephropathy with crescents.

Membranous nephropathy is a common cause of nephrotic syndrome in adults and can be primary or secondary to systemic lupus erythematosus, chronic infection, or drugs. Rapid decline in renal function in patients with membranous nephropathy may be due to renal vein thrombosis, malignant hypertension, or an additional superimposed destructive process involving the renal parenchyma. Crescents are r...
