Acute rejection of a transplanted organ by the recipient’s immune system remains one of the leading causes of pediatric heart transplant failure. While there have been vast improvements in the practice over time, significant variation still exists between transplant centers in the methods used to diagnose acute rejection.
Justin Godown, MD, and colleagues analyzed rejection prevalence and diagnostic practices in pediatric heart transplant centers. Reporting in the Journal of Heart and Lung Transplantation, they found that 22% of pediatric heart transplant patients experienced an episode of rejection in their first year after transplant, most frequently within the first three months.
Most of these episodes were diagnosed using surveillance biopsy. Despite significant differences in methods used to diagnose acute rejection between centers, overall graft survival and patient outcomes did not appear to be impacted by these differences.
