Donor-Derived Cell-Free DNA (dd-cfDNA) Levels in Stable Pediatric Kidney Transplant Recipients
M. Waide, J. Carmody, I. G. Restaino
Pediatrics, Eastern Virginia Medical School, Norfolk, VA
*Purpose: Among adult kidney transplant recipients, donor-derived cell-free DNA (dd-cfDNA) has been validated as a highly sensitive biomarker for graft rejection. Unfortunately, few data are…

Late De Novo Donor Specific Antibodies in Steroid Free Immunosuppression and Delayed Graft Function
S. Karhadkar, M. Falz, A. Diamond, A. Di Carlo, O. Timofeeva
Temple University School of Medicine, Philadelphia, PA
*Purpose: Donor Specific Antibodies (DSA) have been implicated in acute and chronic antibody-mediated rejection. Once developed, they tend to be persistent and lead to transplant…

Post-Transplant Rebound and Not Baseline Anti-A Titers are Associated with Acute Antibody-Mediated Rejection in A₂– to B/O Incompatible Kidney Transplantation
V. Kumar, D. Mompoint-Williams, M. Marques, P. MacLennan, M. Mustian, J. Locke
University of Alabama at Birmingham, Birmingham, AL
*Purpose: Decreased antigen expression among blood group A subtype 2 (A2) donor kidneys allows these organs to be considered as universal donors; under the new…
