Deceased Donor Kidney Transplantation in the Setting of Positive Donor-Specific Antibodies.
1Johns Hopkins University, Baltimore; 2University of Michigan, Ann Arbor.
Recent changes to the kidney allocation system favor highly sensitized transplant candidates, resulting in these patients receiving more offers for deceased donor (DD) kidneys. Despite…2016 American Transplant Congress
Solid Phase Assay Demonstrates High Rates of Allosensitization in Pediatric Heart Recipients.
Allosensitization is a risk factor for rejection, vasculopathy and graft loss. CTOTC-04 is a prospective study assessing the impact of sensitization on a composite of…2016 American Transplant Congress
Early De Novo DSA with T Cell Mediated Rejection (TCMR) Is Associated with Allograft Dysfunction with Chronic Injury.
De novo anti-donor HLA specific antibody (DSA) detected post-renal transplantation is associated with adverse outcomes. However, the relationship between early de novo DSA and subsequent…2016 American Transplant Congress
The Bacterial Enzyme IdeS, Inhibits HLA Antibody-Mediated NK Cell Activation and Cell Cytotoxicity (ADCC) In Vitro.
Background: Antibody-mediated rejection (ABMR) is a major obstacle for successful transplantation in HLA-sensitized patients. ADCC is one of the primary mechanisms for ABMR. IdeS cleaves…2016 American Transplant Congress
Allo-Specific Memory B Cell Recall Responses Are Dependent on B Cell Autophagy.
B cells, and in particular, memory B cells (Bmem) are sources of donor specific antibodies (DSA) that cause allograft injury. Understanding requirements for Bmem function/survival…2016 American Transplant Congress
Criteria for the Diagnosis of Microvascular Inflammation (MVI) in Kidney Transplant Biopsies (KTxBx).
The presence of MVI (Banff glomerulitis "g" score and Banff peritubular capillary "ptc" score) in KTxBx, often related to antibody mediated rejection (AMR), is associated…2016 American Transplant Congress
Utilization of Plasmapheresis and High Dose of Immunoglobulins in the Treatment of the High Level of De Novo Donor Specific Antibodies for the Successful Islet Allotransplantation.
Background.Development of donor specific antibodies (DSA) after islet transplantation has been a poor prognostic factor for graft survival, while no intervention is implemented. Here, we…2016 American Transplant Congress
Optimized Flow Cytometry Crossmatch with Increased Sensitivity and Specificity.
The flow cytometry crossmatch (FCXM) is the standard method to prevent hyperacute rejection after transplantation. Surprisingly, few technical improvements have been introduced to the FCXM…2016 American Transplant Congress
Selective Deletion of Notch2 on B Cells Abrogates Alloantibody Production in Fully MHC-Mismatched Cardiac and Skin Transplant Models.
Alloantibody-mediated injury remains a major challenge for the improvement of long-term graft survival and there is no effective therapy to prevent alloantibody generation post-transplant. The…2016 American Transplant Congress
Comparison of C4d Deposition in Renal Biopsies with Luminex-Based C3d Single Antigen Bead (SAB) Detection.
Recent interest in characterizing the complement-fixing ability of post-transplant donor specific alloantibodies (DSA) resulted in the enhancement of luminex solid phase alloantibody assays to determine…
