A Novel DSA Flow Cytometer Crossmatch (DSA-FXM) to Eliminate Ambiguous Auto- and Allo-FXM Results
Pathology, Stanford University, Palo Alto, CA.
Introduction:Though usually rejected on theoretical grounds, a positive Auto-FXM could result from either or both auto-reactive non-HLA or HLA-antibodies (Ab). Furthermore, a positive Auto-FXM serum…2015 American Transplant Congress
DSA Detected by ELISA-PRA Is Associated With High Risk for Development of AMR in Stable Kidney Transplant Recipients
Background: Donor specific anti-HLA antibodies (DSA) are a major cause of antibody mediated rejection (AMR) and allograft loss, determining how to monitor patients for DSA…2015 American Transplant Congress
Transplant Glomerulopathy in a Novel Model of Chronic Antibody Mediated Rejection Is Associated With DSA and Glomerular IgM
PurposeChronic active antibody mediated rejection (cAMR) and transplant glomerulopathy (TG) are major determinants of long-term allograft survival. However, the contribution of DSA and glomerular immunoglobulins…2015 American Transplant Congress
Tolerance to Graft A-Antigens Following ABO-Incompatible Heart Transplantation (HTx) in a Blood Group A-Transgenic Mouse Model
Purpose: ABOi HTx can be performed safely in infants when ABO antibody (Ab) levels are low or absent. Following ABOi HTx, immune tolerance develops to…2015 American Transplant Congress
Outcomes Following Kidney Transplant With Low Level Positive Flow Cytometric Crossmatch
Introduction: Highly-sensitized kidney transplant (KTx) candidates have difficulty finding a negative crossmatch donor. KTx with low level positive crossmatch might be the next best option.…2015 American Transplant Congress
Novel Flow Cytometry Method for Detecting Complement-Fixing Blood Group IgG Antibody in ABO-Incompatible Renal Transplantation
【Background】We experienced a hyperacute rejection (HAR) in ABO-incompatible renal transplantation (ABO-I RTx) on POD 0. We hypothesized that complement-fixing IgG anti-A/B blood group antibody (anti-A/B…2015 American Transplant Congress
T-Cell Depletion Versus Interleukin-2 Antagonists in a Kidney Transplant Model of Sensitized Rhesus Macaques
[Background] Sensitized patients comprise up to a third of the kidney waiting list. Preformed and newly formed alloantibodies post transplantation (TX) deteriorate graft survival, recall…2015 American Transplant Congress
B Cell Depletion With an Anti-CD20 Antibody Enhances Alloreactive Memory T Cell Response After Transplantation
Pre-transplant B cell depletion in NHP with Rituximab (IgG1 anti-CD20 mAb) combined with cyclosporin A has been shown to promote the survival of islets allografts.…2015 American Transplant Congress
Immune Response to Kidney and Pancreas Self-Antigens Are Associated With Antibody Mediated Rejection in Simultaneous Kidney Pancreas Transplants
Background: Simultaneous kidney-pancreas transplantation (SKP Tx) is performed as treatment option for type-1 diabetes with end stage kidney diseases. Though allograft survival was improved with…2015 American Transplant Congress
Immune-Mediated Injury in Kidney Transplant Recipients Treated With Alemtuzumab Induction and a Steroid Avoidance Protocol
McGill University Health Centre, Montreal, Canada.
Study purpose: We evaluated short-term clinical and immunological outcomes of kidney transplant recipients who received alemtuzumab induction and a steroid-avoidance protocol.Methods: This is a retrospective…
