ARTICLE HIGHLIGHTS
Research background
An impact of donor-specific antibodies (DSAs) on long-term liver allograft survival was found previously in a small cohort of pediatric patients, but the statistical significance was unclear.
Research motivation
The aim of this study was to clarify the importance of DSAs on long-term graft survival in a larger cohort of pediatric patients.
Research objectives
The objective of this study was to emphasize the importance of comprehensive follow-up examinations in clinical practice after pediatric liver transplantation (LT) and contribute to optimizing and standardizing LT follow-ups.
Research methods
This was a cross-sectional retrospective cohort study that compared the outcomes of two patient groups after pediatric LT.
Research results
Our study showed that DSAs significantly impact liver allograft survival. The presence of human leucocyte antigen class II DSAs is associated with chronic rejection, chronic antibody-mediated rejection, graft fibrosis, graft failure, graft loss and re-LT.
Research conclusions
Screening of DSAs and protocol liver biopsies including C4d immunostaining should be standard practice in follow-ups after pediatric LT.
Research perspectives
Further prospective studies should be conducted to explore whether certain DQ-DSAs could be used as a serological marker for the risk of graft loss.
