Narrative ReviewKidney Transplantation in the Older Adult

Patient Survival
In their landmark report, Wolfe et al6 showed that transplant recipients had a 68% decrease in mortality compared with those who remained on the wait list. This survival advantage also was seen in older individuals. Patients aged 60-74 years had 61% lower mortality (relative risk [RR], 0.39; 95% confidence interval [CI], 0.33-0.47) compared with similar patients on the wait list.6 This survival advantage translated into a 4-year increase in life expectancy.
Rao et al7 reported outcomes for 5,567
Deceased Versus Living Donor
Historically, there has been reluctance to use living donor transplants for older adults given the inherent limited life span. However, recent data suggest that living donor kidneys might be the best treatment option for elderly transplant recipients, just as it is for younger individuals. Gill et al8 examined outcomes for transplant recipients older than 60 years by donor age (younger [≤55 years] or older [>55 years]) and source (living or deceased). During the time frame of this study
Quality of Life and Economics
Humar et al17 measured quality of life at 1-year posttransplantation using the 36-Item Short Form Health Survey (SF-36). In this analysis, there were 42 patients who were at least 65 years of age; mean age was 69 years. They found that for 5 of the 8 domains, older transplant recipients had similar or even higher quality-of-life scores than age-matched values from the general US population. The sole domains in which these patients scored lower than the national norms were bodily pain, role
Immunosuppression
The immune response, like other aspects of biology, is significantly affected by the aging process. Although there is heterogeneity among individual patients, in general terms, both innate and adaptive immunity show decreases with increased age.21, 22 These changes are believed to contribute to the observation of decreased acute rejection in elderly transplant recipients. In an analysis involving more than 70,000 kidney transplant recipients, Meier-Kriesche et al23 showed that the incidence of
Evaluation Issues in the Elderly
Older patients with ESRD who are assessing transplantation often have more complex issues to contemplate than their younger counterparts, including cognitive impairment, decreased functional status, and frailty.33, 34 Mild cognitive impairment and dementia occur with greater frequency in older individuals and this increase is even greater in patients with ESRD. For example, only 10%-30% of young and middle-aged dialysis patients have cognitive impairment compared with 30%-55% of those older
