Persistent donor-specific alloreactivity may portend delayed liver rejection during drug minimization in children

Immunoreactivity, immunosuppression requirement and liver graft function was assessed serially for its relationship to delayed/recurrent acute cellular rejection (ACR) after the first 60 days in 36 pediatric primary liver transplant (LTx) recipients. Subjects were classified as rejectors (n=20) or Non-Rejectors (n=16) based on the presence/absence of biopsy-proven ACR in the first 60 days. All children received anti-lymphocyte induction and...
