title: Demographics and response to therapeutic plasma exchange in pediatric renal transplantation for focal glomerulosclerosis: a single center experience.
abstract: Recurrence of FSGS following renal transplantation in pediatric patients is reported as 20-57%. Records of 37 pediatric patients transplanted for FSGS between 1990 and 2005 at a single center were reviewed. Recurrence of disease was assessed by nephrotic range proteinuria and/or FSGS on biopsy. Response to TPE was defined as urine protein to creatinine ratio <0.2. Forty-nine percent of patients were African American, 38% were Caucasian. Fifty-four percent received kidneys from deceased donors and 46% from live donors. Seven patients received preemptive TPE prior to transplantation. Two of these seven patients recurred in the transplanted kidney (28%). Recurrent FSGS occurred in 16 of 37 patients (46%), all of whom received TPE. Recurrence occurred within one month in 12 of 37 patients (32%); eight remitted with TPE (67%). Four of 12 patients failed to respond to TPE. Four of 37 patients (14%) recurred more than one month after transplantation and underwent TPE; three-fourths of patients remitted (75%). Twenty-one of 37 patients (54%) did not recur. One and five yr graft survivals were 84% and 67%, respectively. Median graft survival was 6.7 yr (5.2-10.3). Despite recurrence, FSGS patients can achieve sustained graft function.
