The aim of this study was to evaluate the correlation between epitopic HLA mismatches and the risk of developing DSA in pediatric kidney recipients. There are very few publications concerning epitope HLA mismatch in pediatric kidney transplantation although this topic has been growing in scientific articles in recent years and is promising in adult recipients. The majority of children with chronic renal failure will require multiple kidney transplants during their lifetime and it is therefore important that we can limit the risk of antibody development in order to give them the best chance of survival for their future kidney transplants.
