The UNOS Scientific Renal Transplant Registry data from October 1987 to December 1996, including information on transplants to 537 patients aged 0-2, 2399 patients aged 3-12 and 5986 patients aged 13-21, were used to examine the results of pediatric transplantation by both univariate and multivariate methods. One-year and long-term graft survival rates were adjusted for 9 covariates including donor source and age, recipient sex, race and disease, and transplant year, HLA mismatches, and transplant center. The adjusted 1- and 5-year graft survival rates were 71% and 60% for ages 0-2, 83% and 64% for ages 3-12 and 85% and 57% for ages 13-21. Except for the youngest recipients, these results compared favorably at 1 year with 86% graft survival among 78,418 adults. The projected graft half-life was highest in patients under age 2 (18 years) and lowest among teenagers (7 years) compared with adults and children (11 years). Univariate analyses revealed a significant 10% graft survival advantage with living donor kidneys for all age groups, but especially for those aged 0-2 in whom survival was 66% with a cadaver donor and 84% with a living donor. The youngest recipients experienced early rejection of the mother's kidney less often than the father's (47% vs 28% in the first 6 months, p<0.007). Results in blacks were similar to those in whites during the first year, but the 3.8 year half-life for black teenagers was the lowest among all groups. We conclude that with the exception of very young (age 2 or under) patients, 1-year pediatric renal transplant survival rates are comparable to those in adults, but in the long term, non-compliance and late acute rejection result in an accelerated graft failure rate among teenagers.
