Background: Living donor is the potential solution to organ shortage. This retrospective analysis of UNOS database evaluates the outcome of living donor transplantation across 4 era and report the results in the pediatric population.
Methods: Retrospective analysis of all pediatric living donor transplantation in the U.S. 1987- 2015. The era were: 1987-1994, 1995-2001, 2002-2008 and 2009-2015. The outcome pediatric transplant recipients were then analyzed. Test of equality over strata by Log Rank and Wilcoxon Statistics was used for data analysis. P value of <0.05 was considered significant.
Results: Total: 9005. Significant improvement in graft survival with each successive Cohort. 5 year outcomes: 73.69, 80.9, 82.6, and 87.7% graft survival. At 10 years: graft survival rates 55%, second era 60.4%, and the third era 66% graft survival.

. Rank statistics and test of equality over strata showed p value <0.0001.
The late outcome at 25 years in the first era 10.58. Median age 12, 12, 12, 11 with each successive era, donor age 36, 37, 37, years respectively. Biological relatedness: 98.6, 95.3, 88.5 and79.7%. T50% Living vs DD 11.3 vs 6.6, 12.7 vs 9, >13 vs 9.6 years in each successive era.
Conclusion:
Significant improvement in graft survival in living donor transplants pediatric population. Based on half life, they remain a good choice for pediatric patients. Improved care and advances in immunosuppressive therapies likely resulted in the outcome. Opportunities for improved graft survival still exist for the long term.
