Therapeutic plasma exchange in renal diseases

Abstract

Plasma exchange has been used extensively for over 2 1/2 decades to treat a variety of renal diseases. In this article, the scientific rationale for therapeutic plasma exchange in primary and secondary glomerulonephritis, thrombotic thrombocytopenic purpura and hemolytic uremic syndrome, myeloma cast nephropathy, and allograft rejection are reviewed. The clinical studies that evaluate its efficacy are summarized, with special emphasis on the results of randomized controlled trials, when available. Consensus plasma exchange regimens are presented for diseases in which there is evidence to support its use.
