Acute Graft versus Host Disease (AGVHD) Related to Solid Organ Transplant (SOT) – A Fatal Complication
1University of Cincinnati Medical Center, Cincinnati, OH, 2Hoxworth Blood Center, Cincinnati, OH
*Purpose: This case series highlights our institution's experience with solid-organ transplant (SOT) associated acute graft versus host disease (aGVHD), a rare and deadly complication of…2022 American Transplant Congress
Simultaneous Lung and Kidney Transplant in a Young Patient with COVID-19
*Purpose: Lung transplant is the last resort for COVID-19 refractory ARDS. Dual organ transplant is seen as a relative contraindication at many institutions. We describe…2022 American Transplant Congress
Novel Avenue of Allograft Monitoring: Direct Measurement of Donor-Derived Extracellular Vesicles in Human Plasma
Internal Medicine, Erasmus MC Transplant Institute, Rotterdam, Netherlands
*Purpose: Extracellular Vesicles (EV) - regarded as “snapshots” of their cell of origin - represent promising liquid biomarkers to monitor allograft function post transplantation. Recently,…2022 American Transplant Congress
Racial Differences in HLA Mismatch Potential Among Kidney Registrations
*Purpose: HLA matched kidneys are associated with better long-term post-transplant graft survival. However, prioritizing patients well-matched with an available donor has historically resulted in disparities…2022 American Transplant Congress
HLA-II Subclasses Behave Differently Between Themselves and Between Humans: Cues to Understand Alloreactivity
*Purpose: De novo anti-HLA-II DSAs (dnDSA) are associated with antibody-mediated rejection. However, some patients with anti-HLA-II DSAs will not develop rejection, suggesting that the development…2022 American Transplant Congress
Site-Directed Mutagenesis as a Tool to Investigate Immunogenicity of HLA Epitopes for Humoral Alloreactivity
1Northwestern University, Chicago, IL, 2University Hospital Essen, Essen, Germany
*Purpose: Molecular mismatch load (MML) analysis has been a proposed approach to assess donor/recipient compatibility in support of organ allocation algorithms. While conceptually appealing, MML…2021 American Transplant Congress
Antibodies to Hla Molecules Lead to Induction and Release of Circulating Exosomes with Lung Self-Antigens
St. Joseph’s Hospital and Medical Center, Phoenix, AZ
*Purpose: Antibodies (Abs) to human leukocyte antigen (HLA) (anti-HLA) can injure allograft by complement-dependent/independent mechanisms. Crosslinking of HLA-class I with Abs associate with integrin β4…2021 American Transplant Congress
K562 Cells Expressing HLA-A2 Stimulate Alloreactive CD8+ T Cells
Emory Transplant Center, Emory University, Atlanta, GA
*Purpose: T cell-mediated rejection is a significant factor that leads to graft damage and loss in transplant recipients. Due to the complexity of the TCR:pMHC…2021 American Transplant Congress
Disparities in HLA Representation by Single Antigen Reagents in Different Ethnic Populations
1Keck School of Medicine of USC, Los Angeles, CA, 2Children's Hospital Los Angeles, Los Angeles, CA
*Purpose: It is not possible to test for antibodies against the antigens encoded by every HLA allele due to cost and throughput constraints. When alleles…2021 American Transplant Congress
Antibody-mediated Rejection and Sponge Effect in a Redo Lung Transplant Recipient: A Case Report
Norton Thoracic Institute, St. Joseph's Hospital and Medical Center, Phoenix, AZ
*Purpose: Antibody-mediated rejection (AMR) typically presents with elevated titers of circulating donor specific antibodies (DSA) and increased mean fluorescence intensity (MFI), a surrogate marker for…
