Pre-Emptive Retransplantation in Patients With Chronic Kidney Graft Failure.

ABSTRACT

INTRODUCTION: The aim of this study was to compare the group of patients receiving a new kidney transplant before starting dialysis again (pre-reTR) with a group of patients receiving a new kidney transplant after restarting dialysis (reTR). METHODS: This retrospective cohort included all the kidney retransplantations (second transplantations) between 2000 and 2012 performed at our center and their follow-up until July 2014. We analysed graft and patient survival, rejection rates, and immunologic parameters of these patients. RESULTS: We studied 18 patients who had pre-reTR and 83 who had reTR. In the pre-reTR group no patient had panel-reactive assay (PRA) >10% at any time. In the reTR group 26.5% had PRA >10% at the time of transplantation (P = .014) and 54.2% had a historical highest PRA >10% (P < .001). The rejection rate was 11.1% in the pre-reTR group and 27.7% in the reTR group during the first year post-retransplantation (P = .227). Patient survival rate was 100% in the pre-reTR group at 5 years of follow-up, whereas in the reTR group at 1 year it was 95.2% and 85.9% at 5 years after retransplantation. Allograft survival at 1 and 5 years was 88% and 89%, respectively, in the pre-reTR group. On the other hand, in the reTR group it was 89% after the first year and 65% at 5 years post-retransplantation. CONCLUSION: Pre-emptive renal retransplantation is a feasible option that should be assessed in patients with kidney graft failure and may help to minimize the morbidity associated with dialysis reinitiation.
