Objectives: High recurrence and inferior graft survival rates have been reported for kidney transplant recipients with primary focal segmental glomeru-losclerosis. Plasmapheresis is widely used to treat posttransplant relapsing focal segmental glomer-ulosclerosis, but the effectiveness of prophylactic plasmapheresis remains controversial. Materials and Methods: In this single-center retro-spective study, 21 adult deceased-donor kidney transplant recipients who received prophylactic plasmapheresis were analyzed. Of these, 10 received posttransplant prophylactic plasmapheresis only (less-intensive regimen) and 11 received pre- and posttransplant prophylactic plasmapheresis (more-intensive regimen). Patients with recurrence were treated with steroids and plasmapheresis. Median follow-up was 45 months (interquartile range, 30-107 mo). Results: At last visit, 20/21 patients (95%) were alive and 17/21 (81%) had functioning grafts. Cumulative focal segmental glomerulosclerosis recurrence rate was 38% (8/21): 30% (3/10) in the less-intensive and 45% (5/11) in the more-intensive group (P = .6594). Four of 8 patients (50%) with relapse eventually had graft loss due to recurrence: 100% (3/3) in the less-intensive and 20% (1/5) in the more-intensive group (P = .1429). Complete remission was observed in 25% (2/8) of recipients with recurrence: 0% (0/3) in the less-intensive and 40% (2/5) in the more-intensive group (P = .4643). Two of 8 patients (25%) remained plas-mapheresis dependant: 0% (0/3) in the less-intensive and 40% (2/5) in the more-intensive group (P = .4643). Response rate (complete/partial) was higher in the more-intensive group (80% [4/5] vs 0% [0/3]; P = .1429); however, overall, the 2 regimens did not show signi-ficantly different outcomes. Comparison between this series and a historical control group of 52 patients with primary focal segmental glomerulos-clerosis trans-planted at our center and not receiving plasmapheresis prophylaxis did not demonstrate any advantages. Conclusions: No benefits from prophylactic plasma-pheresis in deceased-donor kidney transplant recipients with primary focal segmental glomerulo-sclerosis were shown. Prospective randomized studies comparing alternative preemptive strategies are warranted. RESULTS: At last visit, 20/21 patients (95%) were alive and 17/21 (81%) had functioning grafts.
