title: A critical look at survival of diabetics with end-stage renal disease. Transplantation versus dialysis therapy.
abstract: The survival of 100 consecutive patients with diabetic nephropathy after treatment with hemodialysis, peritoneal dialysis, or renal transplantation was reviewed at our institution from 1976 to 1982. Standard actuarial survival analysis revealed an overall survival of 83% and 61% at one and two years, respectively. Coronary angiography was used as a screening procedure for renal transplantation. In the dialysis group, 27 patients were considered acceptable transplant candidates on the basis of the coronary angiography but were not transplanted for other reasons. When the survival analysis was limited to those "transplant candidates" the survival rates were 78%, 51%, and 8% at 1, 2, and 5 years, respectively. In comparison, survival after transplantation was 81%, 67%, and 45%, at 1, 2, and 5 years, respectively. In order to eliminate bias, survival comparisons were subsequently made using the Cox Proportional Hazard Model to take into account the time the transplant patients spent on dialysis prior to renal transplantation. When this analysis was performed, there was no significant difference in survival between transplantation and dialysis for the first two years, but overall survival after five years was significantly better after renal transplantation even when the comparison was limited to acceptable transplant candidates who remained on dialysis (P = .04). Survival for patients with significant coronary disease (greater than 70% stenosis of a coronary vessel or moderate to severe left ventricular dysfunction) was analyzed according to therapeutic modality. Although overall prognosis was poor in this group as a whole (1, 2, and 5 year survivals were 76%, 45%, and 19%, respectively), the cardiac patients had a trend to better survival after renal transplantation than when maintained on dialysis (P = .22). In addition to other factors such as quality of life, rehabilitation, and progression of other diabetic complications, the benefit of renal transplantation on patient survival must be considered when deciding between renal transplantation and maintenance dialysis therapy for diabetic patients with renal failure.
