Not All HLA Mismatches Are Equal: Determining the Relative De Novo DSA Induction Capacity of HLA Mismatches
We studied the immunogenicity, defined as the development of de novo DSA (dnDSA), of HLA-A, -B, -DR and -DQ MM (serological) in a cohort of…2018 American Transplant Congress
Peptides Encoded by EBV Latent Cycle Proteins Affect NK Cell Reactivity
Department of Surgery, Stanford University School of Medicine, Stanford, CA.
Introduction: Epstein–Barr virus (EBV) infects more than 90% of adults worldwide and is associated with several malignancies, including post-transplant lymphoproliferative disorder (PTLD). Although EBV infection…2018 American Transplant Congress
Eluates from Fine-Needle Allograft Biopsy Increase Donor-Specific Antibody Identification in Antibody Mediated Rejection
1University of Cincinnati, Cincinnati; 2Hoxworth Blood Center, Cincinnati.
Aim. Antibody mediated rejection (AMR) represents a risk for graft loss, and the presence of circulating donor-specific antibody (cDSA) is a major criterion for AMR…2018 American Transplant Congress
Serum Treatment with Fetal Bovine Serum Significantly Increases Luminex-Based HLA Antibody Assay Specificity by Reducing Heterophile Antibody Interference
Mean fluorescence intensity (MFI) values obtained from Luminex-based HLA antibody assays are used to determine the relative strength of HLA antibodies. However, MFI values can…2018 American Transplant Congress
Do Protocol Biopsies in the Highly Sensitized Improve Renal Allograft Survival? A Single Center Evaluation of 2 Year Graft Function
Organ Transplant Center, University of Iowa, Iowa City, IA.
Highly sensitized kidney transplant recipients (hsKTR) are at an increased risk of antibody mediated rejection (AMR). Following implementation of the new kidney allocation system (KAS)…2018 American Transplant Congress
Impact of Bw4 and Bw6 Epitope Mismatch on Clinical Outcomes after Renal Transplantation
HLA class II epitope mismatch has been shown to impact the long-term survival of kidney allografts. HLA-B alleles are traditionally grouped by the Bw4 and…2018 American Transplant Congress
The Relative Immunogenicity of HLA Mismatches in Adult Liver Transplant Recipients
Determining the immunogenicity of HLA mismatches (MM) may help preventing the appearance of de novo DSA (dnDSA) and avoiding antibody-mediated injuries.We studied the development of…2018 American Transplant Congress
The Brazilian Epitope Virtual Crossmatch Protocol: A Reliable Tool for Increasing Kidney Allocation among Highly Sensitized Patients
Background: In Brazil (BZ), the kidney allocation policy for highly sensitized patients (HS) (PRA ≥ 80%) does not involve prioritization and transplants 10 times less…2018 American Transplant Congress
Informatics Tools for Mapping Molecular HLA Typing Data to UNOS Antigen Equivalencies
Introduction:Molecular HLA typing must be converted to antigen equivalencies for entry into the UNOS database, UNet. Maintaining an up-to-date mapping table for this purpose has…2018 American Transplant Congress
A Calculated Panel Reactive Antibody (CPRA) Calculator Supporting Both Allele-Level and Antigen-Level HLA Specificities
Introduction:The number of HLA alleles represented on Luminex assays has increased over time, allowing for improved characterization of anti-HLA antibody specificity. Calculated Panel Reactive Antibody…
