Current experience with renal transplantation in older patients.

Older patients (greater than 50 years old) are generally considered to be at high risk in renal transplantation, particularly those receiving cadaveric kidneys. The outcome in 53 older patients (mean age, 54 years; range, 50 to 64 years) receiving transplants between January 1, 1980 and December 31, 1986 and followed through June 30, 1987 were analyzed. Before 1984, immunosuppression consisted of azathioprine and prednisone (AP); thereafter, triple therapy (TT)--low-dose cyclosporine, azathioprine, and prednisone--was used. The overall 1-, 3-, and 5-year actuarial patient survival was 87%, 84%, and 84%, respectively. Survival for living related donor (LRD) transplant recipients was 100%, 92%, and 92%; survival for cadaveric (CAD) transplant recipients was 81%, 81%, and 81%. The overall graft survival was 74%, 66%, and 66% at 1, 3, and 5 years, respectively; graft survival was 88%, 81%, and 81% for LRD transplant recipients and 68%, 58%, and 58%, for CAD recipients. The patient and graft survival rates were better in the TT group than in the AP group. Eight patients died after transplantation; six within the first year. The causes of patient death were infection (50%), cardiac (25%), and malignancy (25%). Rejection (56%) and patient death (38%) accounted for most of the grafts lost. Patient and graft survival rates in diabetic patients were not significantly different from survival rates in nondiabetic patients. Results in recipients of ten secondary and one tertiary transplant were poor, with only four of 11 grafts functioning at 1 year.(ABSTRACT TRUNCATED AT 250 WORDS)
