Access to, and outcome of, renal transplantation according to treatment modality of end-stage renal disease in France

Abstract

Background. Although peritoneal dialysis (PD) is recognized as one of the methods of treatment of end-stage renal disease (ESRD), there have been recurrent concerns about the access of patients treated by this modality to kidney transplantation (KTx), as well as reports showing increased complications of KTx in such patients, such as graft thrombosis and infections. Methods. The aim of this study was to provide a comprehensive view of the impact on transplantation of pretransplant modality of treatment of ESRD using a multivariate analysis of the French database. From 1997 to 2000, after exclusion of pediatric patients, multiple transplantations, and living donors, 6420 were patients registered on the waiting list, and 3464 were transplanted. Results. Using a Cox proportional hazard analysis, we found a shorter waiting time for PD patients (RR 0.71, P < 0.0001), which became equivalent to hemodialysis (HD) patients when taking into account the transplant center as a variable (RR 1.0, P = 0.95). Concerning graft survival, only preemptive transplantation had a significant impact, being associated to a decreased risk of graft failure (RR 0.46, P = 0.005). Conclusion. Our study supports the concept that the choice of any pretransplant dialysis modality does not influence waiting time for transplant or the results of transplantation. © 2005 by the International Society of Nephrology.
