Strict consideration of the renal transplant candidate's chronologic age is generally supplanted by more subjective reflection on his (her) physiologic state. In the US, patients over 64 years old represented 9.0% of renal transplant recipients in the year 2000, yet little prior experience is available with which to guide the management of geriatric patients. Two hundred and forty six consecutive recipients of primary kidney transplants at the Yale-New Haven Organ Transplant Center between 1990 and 1995 were included in an outcome analysis. Age at transplantation ranged from 2 to 68 years; the study group consisted of the 16 (6.5%) over age 60. The immunosuppressive protocol was uniform for all patients. There was a disproportionately high use of cadaveric organs by older patients; only 1/16 (6.3%) received a living donor kidney. The overall rate of rejection within the first 90 days was 6.7% of cadaveric recipients over 60 versus 37.6% of younger recipients, P=0.001. Actual patient survival rates at 6 years were 100% of patients younger than 11 years versus 69% (11/16) of those older than 60 years. Death censored 5 year graft survival was 100% in older patients versus 85% among the younger patients. The older and younger patients received quantitatively equivalent immunosuppression, but acute rejection was uncommon in the former (6%) versus the younger cohort (34%). It seems logical to consider whether older renal transplant recipients may benefit from a less aggressive immunosuppression strategy.
