Antibody-Mediated Rejection Can Be Assessed by Histology When DSA Is Unknown or Negative.
Diagnosis of antibody-mediated rejection (ABMR) in kidney transplants currently requires the presence of donor-specific antibody (DSA) and histologic lesions above somewhat arbitrary cutoffs. DSA is…2016 American Transplant Congress
The Combined Effect of Acute Rejection and De Novo Donor-Specific Antibodies on Kidney Allograft Survival.
Division of Renal Diseases and Hypertension, University of Colorado, Aurora, CO.
While dnDSA is associated with graft loss in multiple studies, the clinical context in which dnDSA develops and contributes to graft loss is less well…2016 American Transplant Congress
Alloimmunity Through Non-HLA Epitopes in Kidney Transplantation.
Introduction: An unexpected diversity in the human genome has been identified including more than 2,500 nonsynonymous single nucleotide polymorphisms (nsSNP) and up to 20 homozygous…2016 American Transplant Congress
A Model to Explore the Potential Budget Impact of a Novel Screening Tool for the Detection of Subclinical Rejection Among Kidney Transplant Patients.
1Immucor, Inc, Waukesha, WI; 2Avalare Health, LLC, Washington, DC.
Background: Acute rejection among kidney transplant patients is common, with ~10% of individuals experiencing acute rejection within the first year and rising to 16-17% at…2016 American Transplant Congress
Pediatric Heart Transplantation Across a Positive Cross-Match Is Associated with High Rates of AMR but No Difference in Short Term Graft Loss, Dysfunction and Death (CTOTC-04 study).
Sensitization is common in pediatric heart transplant (HT) candidates. Waitlist mortality is high if a prospective -ve CDC-crossmatch (XM) is required, but HT across a…2016 American Transplant Congress
Characterization of Human Islet Transplant Specific Exosomes in a Xenoislet Transplantation Model.
Department of Surgery, University of Pennsylvania, Philadelphia, PA.
Background: There is a critical need for biomarker platforms for monitoring transplant rejection. We propose that transplant tissues release donor specific exosomes into recipient blood/…2016 American Transplant Congress
Macrophage Specific Deletion of RhoA Impedes Macrophage Functions and Abrogates Chronic Rejection of Cardiac Allograft.
Surgery, The Houston Methodist, Houston, TX.
Objective. Chronic rejection of transplanted organs remains the main obstacle in the long-term success of organ transplantation. Chronic rejection occurs in 40-45% of recipients at…2016 American Transplant Congress
Blockade of HLA Antibody-Triggered Classical Complement Activation by High-Affinity Humanized Monoclonal Anti-C1s Antibody TNT009 – Results of a First-in-Human Phase 1 Trial.
Study purpose: Classical complement may play a key role in ABMR. A promising therapeutic approach could be complement inhibition at the level of key component…2016 American Transplant Congress
Association of Ultrastructural Changes in Renal Allograft Biopsies with Antibody-Mediated Rejection (AMR) and Graft Outcomes.
The role of electron microscopy (EM) in diagnosis of AMR is not well-defined. We sought to examine the EM findings in 796 biopsies from 622…2016 American Transplant Congress
The Effect of Donor-Recipient Relationship on the Immunologic Outcome in Living Kidney Transplantation.
Nephrology, Charite Campus Mitte, Berlin, Germany.
Background. Presensitization and degree of HLA-matching influences immunologic outcome and kidney graft survival. Thus the donor-recipient relationship may influence incidence of immunologic events and outcome…
