Incidence and Factors Associated with De Novo DSA After BK Viremia in Renal Transplant Recipients.
Houston Methodist Hospital, Houston, TX.
Recent literature indicates an elevated rate of de novo DSA (dnDSA) following BK viremia (BKV) in renal transplant recipients (RTR). We sought to review our…2016 American Transplant Congress
Impact of Pretransplant Non-Donor-Specific HLA Immunization: Mainly Class 1 Immunization Leads to Poor Immunologic Outcome and Graft Loss.
Nephrology, Charite, Berlin, Germany.
Background Anti-HLA immunization measured as Panel Reactive Antibodies (PRA) is known to have a negative impact on patient and graft survival. The influence of pre-transplant…2016 American Transplant Congress
Exosome-Like Vesicles Released in Association with Tissue Injury Trigger Anti-LG3 Production.
Pre-transplant levels of autoantibodies to perlecan/LG3 predict poor allograft outcomes in renal transplant patients. We showed previously thatapoptotic exosome-like vesicles (ApoExo) enhance anti-LG3 production and…2016 American Transplant Congress
Glomerular Capillary C4d Staining without Evidence of Rejection Is Associated with Worse Graft Function in ABO-Incompatible Kidney Transplantation.
Objectives: C4d staining in the peritubular capillaries (C4d-PTC) is often observed without evidence of rejection in ABO-incompatible kidney transplantation (ABOI-KTx), and this phenomenon is generally…2016 American Transplant Congress
Real Time Assessment of Kidney Transplant Indication Biopsies by Microarrays: First Results of the INTERCOMEX Study.
1University of Alberta, Edmonton, Canada; 2ATAGC, Edmonton, Canada.
Oncology uses central molecular tissue assessment (MTA) to guide management but the potential of this approach in transplantation is not known. We undertook a prospective…2016 American Transplant Congress
Blocking Fc Receptor in Flow Cytometric Crossmatch: Refining an Old Assay to Improve Patient Management.
Pathology, University of Chicago, Chicago, IL.
Introduction: The crossmatch assay is used to determine sensitization of solid organ transplant recipients to donor-expressed HLA molecules, a potential contraindication to transplant. Multicolor flow…2016 American Transplant Congress
Distinct Effects of Chronic Hyperglycemia on Cellular and Humoral Alloresponses In Vivo.
Background: Diabetes constitutes a significant problem in the transplant recipient. Diabetes is associated with impaired immunity to pathogens but its effect on alloimmunity remains ambiguous.…2016 American Transplant Congress
The Coefficient of Variability of Tacrolimus Levels Can Predict Antibody-Mediated Rejection After Renal Transplantation.
Introduction. Antibody-mediated rejection (ABMR) is the major cause of allograft failure. We studied whether the coefficient of variability (CV) of blood levels of tacrolimus can…2016 American Transplant Congress
Natural Killer CD16/FcR Profiles May Associate with Enhanced Humoral Responsiveness in Heart Transplant Recipients with Cardiac Allograft Vasculopathy.
Natural Killer cells (NK) are immune effectors of antibody-dependent cellular cytotoxicity (ADCC). Their role in mediating adverse effects of Donor-specific anti-HLA antibodies (DSA) towards cardiac…2016 American Transplant Congress
IgM Donor Specific Antibodies Are Frequently Associated with C1q-binding DnDSA in Renal Transplant Recipients.
Background: Recently, the importance of complement-binding de novo DSA (dnDSA) was documented. We aimed to explore the presence of IgM dnDSA according to C1q dnDSA-binding…
