Abstrakt: Living-unrelated donors (LURD) have been widely used for kidney transplantation (KT). We retrospectively reviewed 779 patients who underwent living-donor KT from 2000 to 2012, to compare outcomes of 264 KT from LURD and 515 from living-related donors (LRD), and to identify risk factors for living KT. Median follow-up was 67 months. Mean donor age, total human leukocyte antigen (HLA) mismatches, and HLA-DR mismatches were higher, and mean estimated glomerular filtration rate (eGFR) was lower in LURD. Acute rejection (AR)-free survival (p = 0.018) and graft survival (p = 0.025) were lower for LURD than LRD, whereas patient survival rate was comparable. Cox regression analysis showed HLA-DR mismatches (OR 1.75 for one mismatch; OR 2.19 for two mismatches), recipient age ≤ 42 yr, and donor age > 50 yr were significant risk factors for acute rejection. For graft survival, AR and donor eGFR (OR 1.90, p = 0.035) were significant. We also identified significant impact of recipient age > 50 yr and diabetes for patient survival. However, KT from LURD was not a significant risk factor for AR (p = 0.368), graft survival (p = 0.205), and patient survival (p = 0.836). Our data suggest that donor eGFR and donor age are independent risk factors for clinical outcomes of living KT, which can be related with poor outcome of KT from LURD.
