The Art Rather Than the Science of Non-HLA Antibody Mediated Rejection in Heart Transplantation: A Single Center Experience
Cardiology, Baylor University Medical Center, Dallas, TX
*Purpose: The role of non-HLA antibodies (Ab) in HLA-DSA negative antibody mediated rejection (AMR) following heart transplant (HTx) remains largely unknown.*Methods: Retrospective analysis of all…2020 American Transplant Congress
The 1st Year Posttransplant Course Reliably Predicts Kidney Graft Survival up to 15 Years Using a Machine Learning-Based Modeling Approach
Hannover Medical School, Hannover, Germany
*Purpose: Identification of patients at risk for graft failure can improve individual surveillance and early therapeutic interventions. We used a well-documented patient cohort to establish…2020 American Transplant Congress
The Role of Th17 Polarized T Regulatory Cells in Intestinal Transplant Rejection
*Purpose: Despite profound advances in immunosuppression, intestinal transplantation (ITx) is plagued by frequent cellular rejection. T regulatory cells (Tregs) are key in mitigating immune cell…2020 American Transplant Congress
De Novo DSA in the Setting of Stable Renal Allograft Function Does Not Impair Long-Term Graft Survival
*Purpose: To determine the long-term outcome of renal allograft recipients with de novo DSA (dnDSA) in the setting of stable allograft function.*Methods: A single-center review…2020 American Transplant Congress
The Histological Picture of Indication Biopsies in the First Days after Renal Transplantation
Microbiology, Immunology and Transplantation, KU Leuven, Leuven, Belgium
*Purpose: In preclinical studies, ischemia reperfusion injury and older donor age are associated with renal inflammation in the early phase after transplantation. In human kidney…2020 American Transplant Congress
Factors Influencing Background Cell-Free DNA Levels: Implications for Donor-Derived Cell-Free DNA Assessment in Transplant Patients
*Purpose: Detecting elevated levels of donor-derived cell-free DNA (dd-cfDNA) in the plasma of transplant recipients has been used as a metric to determine graft injury…2020 American Transplant Congress
C-Reactive Protein 1-Year Post-Transplant is Associated with Future Development of Coronary Artery Vasculopathy and Rejection in a Pediatric Heart Transplant Cohort
Congenital Heart Center/Pediatrics, University of Florida, Gainesville, FL
*Purpose: Coronary artery vasculopathy (CAV) is one of the leading causes of mortality beyond 3y post-transplant (OHT). Multiple risk factors are associated with development of…2020 American Transplant Congress
Prospective Donor-Specific CellUlar Alloresponse Assessment for Immunosuppression MinImization in De Novo Renal Transplantation: Results of a Randomized Controlled Biomarker-Guided Trial
*Purpose: Early immunosuppression minimization is associated with higher rates of BPAR. Preformed donor-specific T-cell alloreactivity (DST) assessed with an IFN-γ ELISPOT assay has shown to…2020 American Transplant Congress
ATHENA – Patient and Allograft Outcome Differences after Kidney Transplantation – Germany vs. France
*Purpose: In the ATHENA trial [NCT01843348], efficacy and safety of everolimus in combination with tacrolimus [EVR+TAC] or cyclosporine A [EVR+CyA] vs. TAC and mycophenolic acid…2020 American Transplant Congress
Apoptotic Exosome-Like Vesicles are Associated with Alloimmune Vascular Injury in Kidney Transplant Recipients
*Purpose: There is no non-invasive biomarker of alloimmune vascular injury. We have previously characterized exosome-like vesicles enriched in active proteasome and LG3 (ApoExo) that are…
