Surveillance of Donor-Derived Cell-Free DNA Throughout Treatment of Acute Rejection in Pediatric Renal Transplant Recipients
*Purpose: Donor-derived cell-free DNA (dd-cfDNA) is a dynamic plasma biomarker for allograft rejection with limited data in pediatric renal transplant recipients and few reports describing…2022 American Transplant Congress
The Natural History of De Novo DSA After Kidney Transplantation
*Purpose: De novo donor-specific antibodies(dnDSA) are key in the diagnosis of antibody-mediated rejection(ABMR) and are related to graft loss(GL). Luminex® provides semi-quantitative information with the…2022 American Transplant Congress
Data-Driven Clustering Distinguishes Infection from Rejection During Hospital Admissions Following Pediatric Lung Transplantation
*Purpose: When lung transplantation patients are admitted with respiratory symptoms, distinguishing between episodes of infection and rejection is central to determining immunosuppressive management.*Methods: Data comprising…2022 American Transplant Congress
Development of a Dynamic Map of Peripheral Myeloid Cells Associated with Acute Rejection of Vascularized Composite Tissue Allografts
*Purpose: Myeloid cells are involved in early alloactivation in response to organ allografts and can initiate acute rejection. The heterogeneity of myeloid populations and the…2022 American Transplant Congress
Strada Deficiency Results in Inhibition of Tumor Suppressor Gene Liver Kinase B1 Resulting in Epithelial Mesenchymal Transition Leading to Chronic Murine Lung Allograft Rejection
St. Joseph’s Hospital and Medical Center, Phoenix, AZ
*Purpose: Recently we demonstrated that tumor suppressor gene Liver Kinase B1 (LKB1) is down regulated in lung biopsies and in the circulating exosomes of lung…2022 American Transplant Congress
Ficoll-Based Isolation Alters the Immunogenicity of Islets That Leads to Enhanced Rejection in Allogeneic Hosts
*Purpose: The purification of pancreatic islets has long relied on the time-consuming density gradient separation method. We herein report a filtration method as an efficient,…2022 American Transplant Congress
Comparative Analysis of kSORT Assay for Predicting Acute Renal Allograft Rejection Under Belatacept-Based Immunosuppression
*Purpose: The kSORT (Kidney Solid Organ Response Test) assay uses transcriptomic profiling of peripheral blood to predict the presence of acute rejection (AR) in renal…2022 American Transplant Congress
Technology-Driven Performance Improvement of a Biomarker Panel in Kidney Transplant: OmniGraf
*Purpose: Analyze the impact of the transition from TruGraf microarray to TruGraf PCR on the complementary performance characteristics of TruGraf plus TRAC (OmniGraf).*Methods: Development of…2022 American Transplant Congress
Treatment Modality and Outcomes of Antibody-Mediated Rejection in Pediatric Kidney Transplant Recipients: The PARAMOUr Study
*Purpose: Antibody-mediated rejection (AMR) is the leading cause of graft failure in kidney transplantation, but evidence for effective treatments is limited.*Methods: PARAMOUr is a retrospective…2022 American Transplant Congress
High Pretransplant FGF-23 Level is Associated with Poor Graft Survival and Persistent Vitamin D Insufficiency in Kidney Transplant Patients
*Purpose: Vitamin D [25(OH)D] insufficiency and FGF-23 elevation in chronic kidney disease (CKD) is usually ameliorated after kidney transplantation (KT). However, post-transplant vitamin D insufficiency…
