Comparison of 1-year patient and graft survival rates between preemptive and dialysed simultaneous pancreas and kidney transplant recipients.

ABSTRACT

It is well known that the main decrease in graft and recipient survival rates is observed during the first 12 months after transplantation. Improving results during this period seems to be crucial for the late outcome. The aim of this study was to compare 1-year survival rates of dialyzed and preemptive pancreas and renal graft recipients and their graft function. From November 1999 to January 2005, 42 whole simultaneous pancreas and kidney transplantations (spktx) were stratified into group I (n = 13) recipients who received a preemptive pancreas and kidney transplant versus group II (n = 29) previously dialyzed spktx recipients. The mean time of dialysis for group II was 39 +/- 16.5 months. We assessed 1-year cumulative survival rates for recipients and grafts for each group. The 1-year cumulative survival rate for preemptive graft recipients was significantly higher than that for dialyzed patients before spktx (100% vs 69%; P = .05). For groups I and II 1-year cumulative graft survival rates for kidney grafts were 100% and 89%, respectively, and for pancreatic grafts 84% and 65.5%, respectively. There was a significant improvement in the 1-year survival rate of preemptive spktx recipients compared with patients dialyzed before spktx. However, 1-year pancreas and kidney graft function did not differ significantly between the groups.
