Effect of HLA-DR Mismatches on Graft Outcomes of Kidney Transplant from Elderly Donors
David Geffen School of Medicine at UCLA, Los Angeles, CA
*Purpose: Human leukocyte antigen (HLA)-DR has been shown to be more immunogenic than HLA-A or -B. The impact of HLA-DR mismatches remains unclear among kidney…2021 American Transplant Congress
Bortezomib for Antibody-Mediated Rejection of Renal Transplant in Youth
The Children’s Hospital of Philadelphia, Philadelphia, PA
*Purpose: The purpose of the study was to examine preliminary efficacy and tolerability of bortezomib, a protease inhibitor, in treatment-refractory antibody mediated rejection (AMR) in…2021 American Transplant Congress
Detection of Rejection in Kidney Transplant Patients Using an Algorithm That Combines Donor Fraction and Absolute Donor-derived Cell-free DNA
*Purpose: Donor-derived cell-free DNA (dd-cfDNA) in the plasma of renal allograft patients is a clinically validated biomarker for allograft injury and rejection. Several dd-cfDNA assays…2021 American Transplant Congress
A Case-Match Cohort Comparison of the Safety and Efficacy of Basiliximab for Immunosuppression Holiday in Lung Transplant Patients
1Pharmacy, Massachusetts General Hospital, Boston, MA, 2Massachusetts General Hospital, Boston, MA
*Purpose: Post-transplant complications related to calcineurin inhibitors (CNI) maintenance immunosuppression (MI) may require interim alternative therapies. The goal of this study is to evaluate the…2021 American Transplant Congress
Development and Validation of a Novel Peripheral Blood Based Gene Signature for Acute Rejection Following Renal Transplantation
Department of Urology, Beijing Chao-Yang Hospital, Capital Medical University, Beijing, China
*Purpose: The aim of this study is to utilize advanced machine learning methods to construct a peripheral blood-based gene signature for acute rejection following kidney…2021 American Transplant Congress
Association Between HLA Class II and TLR4 Regulates HLA-II Stimulated P-selectin Expression and Monocyte Capture to Endothelial Cells
Pathology and Laboratory Medicine, University of California Los Angeles, Los Angeles, CA
*Purpose: Antibody-mediated rejection (AMR) is a major obstacle for long-term allograft survival. Donor specific HLA antibodies (DSA) contribute to the process of AMR by binding…2021 American Transplant Congress
VP2 MRNA Distinguishes the Direct Injury and Inflammation Effects of Polyoma Virus (BK) Infection from the Cognate TCMR Response That Follows Immunosuppressive Minimization
*Purpose: BK virus nephropathy (BKN) and T cell-mediated rejection (TCMR) are difficult to distinguish by histology but often coexist due to the necessity for immunosuppression…2021 American Transplant Congress
The Trifecta Study: Calibrating Circulating Donor-Derived Cell-Free DNA at the Time of Indication Biopsies Against the Molecular Phenotype of the Biopsy Reveals a Prominent Association with NK Cell Genes
1Alberta Transplant Applied Genomics Centre, Edmonton, AB, Canada, 2Natera Inc., San Carlos, CA
*Purpose: The international, multicenter, prospective Trifecta study was designed to calibrate dd-cfDNA% measurements in blood at the time of indication biopsy against the molecular characteristics…2021 American Transplant Congress
Recipient Neutrophils Producing Myeloperoxidase Provoke Nk Cell and Monocyte/macrophage Activation During Acute Antibody-mediated Rejection of Kidney Allografts
Lerner Research Institute, Cleveland Clinic, Cleveland, OH
*Purpose: Dysregulated donor-specific antibody (DSA) responses are induced in B6.CCR5-/- mice transplanted with complete MHC mismatched A/J kidney allografts and mediate acute graft rejection. Acute…2021 American Transplant Congress
Initial Experience with TrugrafTm Gene Expression Profile and TracTm Dd-cfdna Testing in Kidney Transplant Recipients Suggests Synergy and Enhanced Management within the First Year Post-transplant and Beyond
Nephrology, Baystate Medical Center, Springfield, MA
*Purpose: Non-invasive validated rejection biomarkers are now available to monitor kidney transplant patients (KTRs). Two such biomarkers are; TruGrafTM (TG) gene expression profile validated to…
