BACKGROUND Acute rejection (AR) is an important risk factor for long-term renal graft loss. Furthermore, donor age is also associated with graft outcome. We analyzed the combined effects of cadaver donor age and AR on long-term graft survival. METHODS A retrospective review was made of 112 cadaver renal transplants at a single center. Only grafts functioning at least 3 months were included in this analysis. RESULTS The 3-year survival of AR-free grafts was superior to that of grafts with AR (98% vs 67%, P < .001). Within the AR cohort donor age > 50 years (P < .05) had an additional negative impact on graft survival. The 3-year survival of an older donor graft with AR was 33% versus 82% for a younger donor graft with AR. CONCLUSIONS AR was a significant predictor of long-term graft loss. Older donor kidneys with AR had poorer graft survival than did younger donor kidneys with AR.

D000367	Age Factors	Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
