Infectious Complications With Plasmapheresis in Rapidly Progressive Glomerulonephritis

We recently used plasmapheresis to treat eight patients with rapidly progressive glomerulonephritis. Life-threatening infections developed in five patients, three of which were caused by opportunistic pathogens. In contrast, only two infections occurred in 21 patients with similar renal disease treated with immunosuppressive drugs but not with plasmapheresis. Although infectious complications of plasmapheresis therapy have not been emphasized previously, our experience, coupled with that of previous reports, suggests that serious infections will develop in one third of patients undergoing plasmapheresis for renal disease. Plasmapheresis should be used with caution in patients with rapidly progressive glomerulonephritis. ( JAMA 244:2423-2426, 1980)
