Abstract

Objectives: The number of renal transplants in elderly patients is increasing as age per se does not constitute a contraindication to transplant. We compared renal transplant outcomes in elderly recipients versus a group of middle-aged patients.

Materials and methods: Our retrospective casecontrolled study compared elderly transplant recipients (n = 252; > 60 y old) with a matched cohort of younger adult recipients (n = 710; between 40 and 60 years old) who underwent renal transplant at the Hamed Al-Essa Organ Transplant Center of Kuwait between 2000 and 2014. Demographic characteristics, comorbidities, complications after transplant, and graft and patient outcomes were compared between groups.

Results: There were 252 elderly kidney transplant recipients (mean age of 65.5 ± 4.8 y; 59.52% males) and 710 younger adult patients (mean age of 49.3 ± 5.5 years; 61.4% males). Most donors were males in their thirties. Deceased donors predominated in the younger adult group, whereas living unrelated donors predominated in the elderly group (P < .05). Diabetes represented the most common cause of endstage kidney disease. Younger patients tended to receive heavier induction therapy but comparable maint enance immunosuppression. Posttransplant diabetes was higher in younger patients; however, there were more elderly patients with micro- and macroangiopathies (P < .05). No significant differences were shown between groups with regard to patient or graft survival (P > .05). This could be attributed to a significantly higher number of patients with cardiovascular risks, less rejection episodes, and higher number of malignancies in the elderly group (P < .05).

Conclusions: Due to relatively less potent immunosuppression, elderly patients experienced lower rejection rates and better graft survival; however, patient survival was lower due to higher cardiovascular risk factors. Older patients should not be discouraged from living-donor renal transplant. Targeted research studies on protocols for the elderly are needed.
