Pre-emptive deceased-donor kidney transplant: A matched cohort study

Introduction: Currently, kidney transplantation is the treatment of choice for patients with kidney disease who require replacement therapy. Dialysis is a necessary step, but not mandatory prior to transplantation. There is the possibility of pre-emptive transplantation or transplantation in pre-dialysis, that is, without previous dialysis. The aim of the present study is to evaluate the result of our experience with a pre-emptive kidney transplant from a deceased donor. Materials and methods: Retrospective, observational, matched cohort study. We compared 66 pre-emptive with 66 non pre-emptive recipients, who received a first renal graft performed at our centre, matched by age and gender of donors and recipients, time of transplant, immunological risk, immunosuppression and cold ischaemia time. Early graft loss, incidence of acute rejection, delayed graft function, renal function at 12 and 36 months and graft and recipient survival were assessed in this period. Results: The percentage of recipients who presented early graft loss, delayed graft function and acute rejection was similar in both groups. No differences were observed in their renal function at 12 and 36 months after transplantation, as well as the actuarial survival of patients (P = 0.801) and grafts (P = 0.693) in the studied period. The total calculated cost of the period on dialysis for the control group was 8,033,893.16 euros. Conclusions: Pre-emptive transplantation can yield comparable outcomes to those for post-dialysis kidney transplantation, and results in better quality of life for patients with end-stage kidney disease, as well as a reduced cost.
