    Abstract:
    OBJECTIVE: Clinical characteristics of recipients of deceased donor renal transplantations were evaluated in the period before versus after implementation of The National Allocation System (NAS). PATIENTS AND METHODS: We evaluated retrospectively clinical profiles of the 42 after NAS (June 2008-December 2010) versus 42 consecutive deceased donor renal transplantation patients before NAS. Patient and graft survival rates were assessed using the Kaplan-Meier method; graft function was assessed based on creatinine clearance with the Cockcroft Gault equation. Patient and donor data were obtained from medical records. RESULTS: Recipients were older in the pre-NAS group (39 ± 8 vs 33 ± 8 years, respectively; P = .001) and median duration of preoperative dialysis was longer in the post-NAS group (103 ± 61 months vs 50 ± 36 months, respectively; P = .000). The average number of human leukocyte antigen-mismatched antigens were pre-NAS 3.4 ± 1.0 versus post-NAS 3.9 ± 1.2 (P = .05). Considering the recipients serological status 9 were hepatitis C virus (HCV)(+) and 2 hepatitis B virus (HBV)(+) among the post-NAS versus no HBV(+) and only 1 HCV(+) patient pre-NAS. Kaplan-Meier analysis of graft survival rates showed 90% at 1 and 85% at 3 years pre-NAS. Similar to 95% at 1 and 86% at 3 years for the post-NAS group (P > .05). Likewise, patient survival rates for both groups at 1 and 3 years were 97%. The mean parameter of donor age, allograft loss, cold ischemia time, patient death, number of retransplantations, HBV(+) patients, and delayed graft function were similar between groups (P > .05). DISCUSSION: After NAS the transplant recipients were older, had a longer duration of dialysis, greater number of HLA mismatched antigens and, more HCV(+). No differences were observed in short-term patient and graft survival rates.
