title: Reduction of post-transplant proteinuria due to recurrent mesangial proliferative (IgM) glomerulonephritis following plasma exchange.
abstract: A patient developed recurrent IgM proliferative glomerulonephritis and a nephrotic syndrome following HLA-identical living donor renal transplantation. Two intensive five-day courses of plasma exchange were followed by sustained reduction of proteinuria. Renal function has remained normal at all times. Immune complex sizing revealed a high titer of middle range complexes (mol. wt. 1 x 10(6) daltons app.); immune complex clearance following an antigen load was not improved by plasma exchange suggesting no alteration of reticulo-endothelial function. Possible mechanisms of benefit are discussed.
