Anti-PLA 2R antibodies in membranous nephropathy: ready for routine clinical practice?

J.M. Hofstra, J.F. Wetzels


The identification of circulating autoantibodies against
the M-type phospholipase A2 receptor (anti-PLA2R) in
patients with idiopathic membranous nephropathy (iMN)
has been a major discovery. Anti-PLA2R can be measured by a commercially available test. It is suggested that measurement of anti-PLA2R will change the diagnostic strategy in patients with nephrotic syndrome and may guide treatment in patients with iMN. We review the available evidence and caution against the immediate injudicious use of the assay in routine clinical practice.
