Many pediatric centers utilize a variety of protocols including preemptive plasmapheresis to prevent the recurrence of FSGS post-transplant. But the effectiveness of this expensive, time-consuming process of plasmapheresis in the prevention of FSGS recurrence is still unclear. We retrospectively reviewed all pediatric cases of FSGS in our center that received a kidney transplant and compared the transplant and patient outcomes of those transplanted after 2006 who received pretransplant plasmapheresis to those prior to 2006 who did not. Of the 57 children with FSGS, 31 and 26 were transplanted before and after 2006, respectively. The cohorts differed significantly in keeping with the center immunosuppression protocol changes, and prior to 2006, the recipients were significantly younger. All children with FSGS transplanted after 2006 underwent three and one sessions of 1.0 plasma volume/exchange plasmapheresis with fresh frozen plasma replacement prior to the transplant in living and deceased donors, respectively, in addition to five sessions of every other day post-transplant pheresis. The incidence (27% vs 26%, P = 1.0) and time to recurrence of FSGS in the kidney allograft (P =.22) were not significantly different in patients that did and did not undergo prophylactic plasmapheresis. We need to re-evaluate the role of preemptive plasmapheresis in the prevention of FSGS recurrence in a prospective multicenter study.
