Effect of early graft function on patient survival in renal transplantation.

ABSTRACT

The influence of early graft function on long-term graft survival has been widely reported but its association with patient survival has received less attention. We investigated the effect of early renal function on patient survival and on cardiovascular disease after renal transplantation among 532 transplant patients who had grafts functioning for >1 year. Patients were classified into two groups, depending on the early creatinine clearance (< or >60 mL/min). We analyzed graft and patient survival, posttransplant cardiovascular disease, and the principal causes of death. Five- and 10-year graft and patient survival were lower among the group with worse early renal function. The main cause of death was vascular disease. Poorer early renal function increased the risk (RR) of patient death by 2.2-fold, and also the presence of posttransplant cardiovascular disease. In conclusion, patients with poor levels of early graft function are at an increased risk of death. These high-risk groups should be targeted for interventional studies to improve patient survival.
