This study examines the association between HLA antibody (PRA) and post-transplant outcomes in pediatric heart recipients, finding that an elevated PRA determined by solid phase assay remains a significant risk factor in the modern era.

K., MD,b Naftel D.C., PhD,b Hsu D., MD;h on behalf of the Pediatric Heart Transplant Study Investigators Abstract Data from patients in the Pediatric Heart Transplant Study (PHTS) registry transplanted between 2010 and 2014 were analyzed to determine the association between HLA antibody (PRA) determined by solid phase assay (SPA) using Luminex or flow cytometry with a positive retrospective crossmatch and the post-transplant outcomes of acute rejection and graft survival. A total of 1459/1596 (91%) recipients had a PRA reported pre-transplant; 26% had a PRA >20%. Patients with a PRA>20% were more likely to have congenital heart disease, prior cardiac surgery, extracorporeal membrane oxygenation support at listing, and waited longer for transplantation than patients with a PRA <20%. Patients with higher PRA% determined by SPA were predictive of a positive retrospective crossmatch determined by flow cytometric method (p<0.001). A PRA >50% determined by SPA was independently associated with worse overall graft survival after first month of transplant in both unadjusted and adjusted for all other risk factors. In this large multicenter series of pediatric heart transplant recipients, an elevated PRA determined by SPA remains a significant risk factor in the modern era.
