Noninvasive diagnosis of primary membranous nephropathy using phospholipase A2 receptor antibodies

Idiopathic membranous nephropathy and anti-phospholipase A2 receptor antibodies.

Phospholipase A2 receptor antibodies in membranous nephropathy: unresolved issues.

The discovery of theM-type phospholipase A2 receptor (PLA2R) as a major antigen in idiopathic membranous nephropathy (iMN) was a breakthrough and established iMN as an autoimmune disease.1 Subsequent studies confirmed that antibodies against PLA2R were present in approximately 70% of incident iMN patients (reviewed by Hofstra and Wetzels2). The potential role ofmeasuring PLA2R antibodies for cl...

Anti-phospholipase A2 receptor antibody in membranous nephropathy.

The M-type phospholipase A2 receptor (PLA2R) is a target autoantigen in adult idiopathic membranous nephropathy (MN), but the prevalence of autoantibodies against PLA2R is unknown among Chinese patients with MN. Here, we measured anti-PLA2R antibody in the serum of 60 patients with idiopathic MN, 20 with lupus-associated MN, 16 with hepatitis B (HBV)-associated MN, and 10 with tumor-associated ...

Anti-Phospholipase A2 Receptor Antibodies in Membranous Nephropathy: from Bench to the Patient

Membranous nephropathy (MN) is a glomerular disease histologically characterized by an uniform thickening of glomerular basement membranes (GBM) caused by subepithelial electrondense deposits of immune complexes, in which the antibody is an IgG. In about 2/3 of cases the etiology of MN is unknown and the disease is called primary or idiopathic. In the remaining cases MN may be secondary to syst...

Differential diagnosis of membranous nephropathy with autoantibodies to phospholipase A2 receptor 1.

Membranous nephropathy (MN) accounts for most cases of the nephrotic syndrome in adults. Recently, studies on the underlying pathomechanisms led to the identification of the podocyte M-type receptor for secretory phospholipase A2 (PLA2R1) as a target antigen of circulating autoantibodies. Autoantibodies to PLA2R1 may not only play a role in the development of primary MN, but also serve as a mar...
