Abstract
To assess the influence of donor age on renal allograft outcome, we retrospectively analyzed all 169 consecutive cyclosporine-treated live related donor kidney transplants, of whom 40 were HLA identical siblings. All recipients were similar with respect to demographic and immunologic characteristics. Incidence of rejection episodes and graft survival rates at 1 and 5-year posttransplant were independent of donor age. Best renal function, as assessed by the mean of the lowest 3 serum creatinine concentration levels in the first 2 months posttransplant correlated positively with donor age, particularly among HLA mismatched male recipients (r = 0.4, P < 0.002). Short and intermediate term renal function was inferior, but stable in the older donor recipient group when compared to the younger cohort. Mean serum creatinine levels at 5 years in recipients of kidneys from older donors (age > 55 years) was 2.6 mg/dl compared to 1.7 and 1.9 mg/dl in recipients of kidneys from donors between the ages of 18-39 and 40-54 years, respectively (P < 0.001). In view of the universal shortage of organs and the negligible morbidity to the donors, our results should not discourage the use of kidneys from elderly (age > 55 years) donors.
