Transplantation versus dialysis in diabetic patients with renal failure.
Studies suggesting that transplantation is better than dialysis for diabetic patients with renal failure may be biased by the more favorable pretreatment prognosis of transplanted patients. Therefore, to provide a fairer comparison we controlled for pretreatment clinical state, categorized treatment received, and assessed mortality, major morbid events, and hospitalization in 51 diabetic patients who began therapy between 1970 and 1980. Fourteen patients were treated by transplantation and 37 by dialysis. The mean waiting period for transplantation was 5 months. The average age of transplanted patients was 40.9 years and of dialyzed patients 59.6 years. When we controlled for this age disparity and other factors (duration of diabetes and heart failure) that affect prognosis in end-stage renal disease (ESRD), the mortality with both transplantation and dialysis was similar to that expected from the overall mortality rate of the 51 study patients. Treatment received had no effect on mortality; the observed deaths compared with deaths expected from pretreatment status were 8 and 7.3 for transplantation and 30 and 30.7 for dialysis. We also compared major morbid events (blindness, amputation, stroke, severe heart failure, and myocardial infarction) and hospitalization in transplanted patients with the 24 dialyzed patients who survived long enough (5 months) to be eligible for transplantation. The number of major morbid events was 2.7 per 10 patient-years in the transplanted group and 3.4 in the dialyzed group. Hospitalization was 151.3 d/yr in transplanted patients and 55.6 d/yr in dialyzed patients (P less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
