title: Non-Heart-Beating Donor Kidney Transplantation Survival Is Similar to Donation After Brain Death: Comparative Study With Controls in a Regional Program.
abstract: Non-heart-beating donors (NHBD) are an increasing source of organs for kidney transplantation (KT) compared with donation after brain death (DBD), but the results in each regional transplantation program require local analysis. We compared 164 KT from NHBD (83 Maastrich type II A-B [T2] and 81 type III [T3]) with 328 DBD controls. NHBD kidneys were implanted with less cold ischemia, mean time on renal replacement therapy for NHBD recipients before transplantation was less too, and a higher proportion of thymoglobulin was also used. Besides NHBD-T2 more frequently showing the A group and patients being younger (48.9 ± 11 vs DBD 55.2 ± 15 years old; P < .001), there was a lower proportion of retransplant recipients and HLA sensitization; HLA-DR compatibility was slightly worse. Proportion of nonfunctioning allograft and necessity of dialysis after transplantation for NHBD were 4.9 and 68.3% versus DBD 4.3 and 26.9% (P < .001); renal function after a year was significantly less in NHBD (serum creatinine 1.79 ± 0.9 mg/dL vs 1.46 ± 0.5 in DBD; P < .001). NHBD recipient survival rates were 96% and 96% for the 1st and 3rd years, respectively, versus 96% and 94% for DBD, respectively (not significant [NS]). Graft survival rates censored by death were 91% and 89% (1st and 3rd years, respectively) versus 95% and 94% for DBD, respectively (NS). We did not find significant differences about survival between NHBD-T2 and T3. In the multivariable survival study (Cox, covariables with statistical significance demonstrated previously in our region), NHBD is not a prognosis factor for recipient or graft survival. Regarding current criteria for choosing donors and the graft allocation applied in Andalusia, short-term survival for NHBD transplantation is similar to DBD. Renal function in the short term is slightly worse, which is why it is important to monitor results over a long term, especially those from NHBD-T2.
