Kidney transplantation in children has shown steady improvement in graft survival outcome over the last decades. Using data obtained from the transplantation registry of our center between 1984 and 2012, we assessed the independent determinants of graft failure using the Cox proportional hazards regression. Altogether, 128 recipients younger than 18 years of age at the time of kidney transplantation and who had >3 months graft survival were studied. During 9.95 years of medium follow-up, 27 censored graft failures occurred. Censored graft survival rates at 5, 10, 15, and 20 years post-transplantation were 93%, 82%, 70%, and 63%, respectively. Studied factors included recipient and donor age, recipient gender, dialysis vintage, donor/recipient cytomegalovirus (CMV) serology, panel-reactive antibody percentage, human leukocyte antigen mismatching, previous transplantation number, donor type (deceased vs living donation), cold ischemia time, induction therapy with antithymocyte globulin, occurrence of acute tubular necrosis, and development of acute rejection. Using univariate analysis, the significant predictors for graft-censored failure were adult donor (PÂ < .001), recipient age (PÂ = .035), human leukocyte antigen mismatching (PÂ = .025), antithymocyte globulin induction (PÂ = .03), and development of acute rejection (PÂ < .001). Two factors independently predicted graft-censored failure in multivariate analysis. The odds ratios for graft failure in patients with acute rejection and in children who received an organ of an adult were 3.744 and 4.962, respectively. Pediatric recipients should receive the first priority for allografts from pediatric donors and acute rejection should be meticulously prevented.
