Risk Stratification of Kidney Transplant Patients According to the Different Level of HLA-DQ Disparities
*Purpose: It is becoming clear that de novo donor-specific antibodies (dnDSA) against HLA-DQ are the most prevalent and the leading cause of chronic antibody-mediated rejection…2021 American Transplant Congress
The Impact of De Novo Dose-Adjustment Strategies with Tacrolimus XR (LCP-Tac) in Kidney Transplant Recipients
Medical University of South Carolina, Charleston, SC
*Purpose: LCP-Tac is a once daily formulation of tacrolimus indicated for the prophylaxis of rejection in de novo kidney transplant recipients. It provides less variable…2021 American Transplant Congress
Mortality in Organ Transplant Recipients with Covid-19 Compared to Non-transplant or Waitlisted Patients: A Meta-analysis
Rhode Island Hospital/Brown University, Providence, RI
*Purpose: Organ transplant recipients (OTR) are considered at high risk for adverse outcomes from COVID-19. However, mortality rates range from 30%. Some studies found that…2021 American Transplant Congress
Comorbidity Burden is Associated with Increased Waitlist Mortality Among NASH Patients
*Purpose: Nonalcoholic steatotic hepatitis (NASH) is an increasing and common indication for liver transplantation. The association between increased comorbidity burden and risk of death on…2021 American Transplant Congress
Dd-cfdna Can Guide Safe Reintroduction of Immunosuppression in Kidney Transplant Recipients with Covid-19
1CareDx, Brisbane, CA, 2Transplant Institute, NYU Langone Health, New York, NY
*Purpose: COVID-19 infection is associated with 25% mortality in kidney transplant recipients (KTRs). Reduction of anti-metabolite immunosuppressants during the acute COVID-19 illness is a common…2021 American Transplant Congress
Reduction in Hospitalizations and Deaths in Covid-19 Positive Abdominal Organ Transplant Recipients Following Implementation of A Protocol for Early Treatment with Bamlanivimab
Abdominal Transplantation, Keck Medical Center of USC, Los Angeles, CA
*Purpose: In December of 2020, our program was identifying up to twenty COVID-19 positive abdominal transplant recipients per week. After seeing our high hospitalization and…2021 American Transplant Congress
Dna-pkcs Regulation of the Allogeneic Immune Response
University of Arkansas, Little Rock, AR
*Purpose: Organ transplantation is life-saving and continued investigations into immunological mechanisms that drive organ rejection are needed to improve immunosuppression therapies and prevent graft failure.…2021 American Transplant Congress
A Mechanistic Evaluation to Guide the Optimal Immunosuppression Adjustment Strategy in Transplant Patients with COVID-19
*Purpose: The optimal management of immunosuppression in transplant patients infected with COVID-19 is unknown. Reduction in calcineurin inhibitors or antimetabolite doses is often performed in…2021 American Transplant Congress
Contribution of T-bet Expressing CD27+ CD21- Activated Memory B Cells Poised for Plasma Cell Differentiation to Antibody-mediated Rejection of Kidney Transplants
*Purpose: Alloimmunity triggered by donor-specific antibodies (DSAs) and ensuing development of antibody-mediated rejection (ABMR) are detrimental to organ transplants. Yet, the cellular states underlying B…2021 American Transplant Congress
Accelerated Bronchiolitis Obliterans After Lung Transplant Promoted by an ATG16L1 Mutation is Coupled to Mitochondrial Damage and Metabolic Alterations in Monocyte-derived Antigen Presenting Cells
1Washington University, Saint Louis, MO, 2UT Southwestern Medical Center, Dallas, TX
*Purpose: Bronchiolitis obliterans (BOS) remains a major cause of death for lung transplant recipients, and the mechanisms that drive BOS remain poorly understood. It is…
