Objectives: To compare the donor outcomes of living donor kidney transplantation between standard donors (SDs) and marginal donors (MDs) including diabetic patients (MD + DM). Methods: MDs were defined according to Japanese guideline criteria: (a) age >70-years, (b) blood pressure ≤130/80 mmHg on hypertension medicine, (c) body mass index >25 to ≤32 kg/m2, (d) 24-h creatinine clearance ≥70 to <80 ml/min/1.73 m2, and (e) hemoglobin A1c > 6.2 or ≤6.5 with oral diabetic medicine. Fifty-three of 114 donors were MDs. We compared donor kidney functions until 60 months postoperatively. Results: No kidney function parameters were different between SDs and MDs. When comparing SD and MD + DM, MD + DM had a lower postoperative eGFR (48 vs. 41 (1 (month), p =.02), 49 vs. 40 (12, p <.01), 48 vs. 42 (24, p =.04), 47 vs. 38 (36, p =.01)) and the percentage of residual eGFR (SD vs. MD + DM: 63 vs. 57 (1 (month), p <.01), 63 vs. 57 (2, p <.01), 64 vs. 56 (12, p <.01), 63 vs. 57 (24, p <.01), 63 vs. 52 (36, p =.02)). However, when MD with a single risk factor of DM was compared to SD, the difference disappeared. Nine out of 12 (75%) MD + DM had ≥2 risk factors. Conclusions: Although long-term observation of donor kidney function is necessary, careful MD + DM selection had the potential to expand the donor pool.
