Renal allografts from donors older than 70 years are useful for single transplantation.

Kidney transplantation has been related in elderly recipients to a greater longevity compared with dialysis. Due to the scarcity of donors, transplantation of older patients depends on the acceptance of older donors. We compared the characteristics and evolution of transplants from donors >or=70 years (n = 53) with those from donors >55-<70 years (n = 201). Group D >or=70 included older recipients (65.37 +/- 4.9 vs 55.92 +/- 9.66 years; P = .000) and more women (62.3% vs 45.3%; P = .02), with more peripheral arterial disease (10.9% vs 2.4%; P = .011). No differences in donor characteristics were observed. Induction treatment with thymoglobulin or basiliximab was more common in D >or=70 (81.1% vs 57.3%; P = .006), with no differences in other immunosuppressive drugs. The incidence of delayed graft function (DGF) was similar (P = .82), with a trend to a lower incidence of acute rejection episodes among D>or=70 (11.8% vs 22.5%; P = 0.09). Serum creatinine and proteinuria levels did not differ during follow-up (P > .05). Patients in D >or=70 displayed more episodes of urinary sepsis (19.1% vs 6.4%; P = .008), but no differences were observed in cytomegalovirus (CMV) infection (P = .629), neoplasia (P = .118), ischemic cardiopathy (P = .642), or hospital readmission due to infections (P = .567). Graft survivals at 5 years were 70% and 75% (P = .279) among groups D >or=70 and D>55-<70, respectively, and patient survivals at 5 years were 88% and 88% (P = .63), respectively. In conclusion, our study showed that selected kidneys from donors older than 70 years were followed with excellent graft and patient survivals, permitting older patients on renal replacement therapy to benefit from renal transplantation.
