摘要

The vast majority of the renal indications for plasma exchange are related to immunoglobulin removal. Immunoglobulins, especially IgG, have a relatively long half-life. Thus in antibody-mediated disease, there could be persistence of significant amounts of antibody in the circulation despite cessation of antibody production. The aim of plasma exchange is to significantly reduce circulating antibodies. Removal of the circulating antibodies constitutes the rationale for using plas-mapheresis to treat antibody-associated glomeruloneph-ritis (GN). Although small molecular weight substances are removed by plasma exchange, their large volume of distribution and short half-lives make plasma exchange an inefficient means of extracorporeal removal of these substances. For instance, some complement proteins have a half-life of 2 days.
