The authors present their experience with therapeutic plasmapheresis (TPE) using membrane filters at the pediatric dialysis unit of a referral center. Between January 2006 and December 2010, 486 sessions of TPE were performed in 39 patients (range 6-17 y), chiefly for atypical hemolytic uremic syndrome (HUS, n = 22), crescentic glomerulonephritis (n = 8) and focal segmental glomerulosclerosis (n = 5). Satisfactory response was noted in 32 patients, particularly with HUS (n = 22) or crescentic glomerulonephritis (n = 6). Adverse effects included chills or urticaria (n = 8 sessions), hypocalcemia (n = 6) and hypotension (n = 5). The present findings highlight the safety, efficacy and feasibility of TPE using membrane filtration.
