Asian Transplantation Week 2016Kidney transplantationEffect of Donor-Recipient Age Match in Expanded Criteria Deceased Donor Kidney Transplantation

PurposeOur objective was to investigate the effects of age on patient and graft survival in expanded criteria donor (ECD) renal transplantation.MethodsBetween February 2000 and December 2015, we analyzed 405 deceased donor renal transplants, including 128 grafts (31.9%) from ECDs. Based on recipient age and ECD criteria classification, the recipients were divided into four groups: Group I, non-ECD to recipient age <50 years; Group II, non-ECD to recipient age ≥50 years; Group III, ECD to recipient age <50 years; and Group IV, ECD to recipient age ≥50 years.ResultsAmong the four groups, there were significant differences in baseline characteristics (age, body mass index [BMI], cause of end-stage renal disease [ESRD], number of kidney transplantations, and use of induction agent). The mean modification of diet in renal disease (MDRD) glomerular filtration rate (GFR) level at 1 month, 6 months, 1 year, 3 years, and 5 years after transplantation was significantly lower in patients with ECDs but MDRD GFR level at 7, 9, and 10 years did not differ significantly (P = .183, .041, and .388, respectively). There were no significant differences in graft survival (P = .400) and patient survival (P = .147).ConclusionOur result shows that, regardless of recipient age, kidney transplants donated by deceased ECDs have similar graft and patient survival.
