Assessment of Donor Specific Anti-HLA Antibodies throughout SLK Transplantation
Simultaneous Liver-Kidney transplantation provides a mechanism to protect the transplanted kidney from recognition by the recipient's immune response compared to solitary kidney transplant alone. High…2018 American Transplant Congress
APRIL/BLyS Blockade Improves Depletion of Antibody Secreting B Cells Compared to BLyS Blockade Alone in Sensitized Murine Kidney Transplant Model
1Surgery, University of Wisconsin, Madison, WI; 2Medicine, University of Wisconsin, Madison, WI.
Introduction: Antibody mediated rejection (AMR) remains a significant problem in highly sensitized individuals undergoing kidney transplantation. APRIL (A Proliferation Inducing Ligand) and BLyS (B Lymphocyte…2018 American Transplant Congress
Identification of Human SIRPa Diversity That Could Regulate Innate Allorecognition
Innate allorecognition is a process by which myeloid cells, such as monocytes, distinguish syngeneic from allogeneic cells. Monocytes that recognize donor cells as non-self differentiate…2017 American Transplant Congress
A Low-Dose Anti-Hepatitis B Immunoglobulin Regimen for Prophylaxis of Hepatitis B Recurrence.
Liver and Transplantation Surgery, Chang-Gung Memorial Hospital, Taoyuan, Taiwan
Background: Hepatitis B virus (HBV)-related liver disease is the major indication of liver transplantation in Asian countries. Combination of anti-hepatitis B immunoglobulin (HBIg) and anti-viral…2017 American Transplant Congress
Improving Value by Standardizing the Use of IVIG Amongst Pediatric Solid Organ Transplant (SOT) Patients.
Background: Given the high cost of pharmaceuticals (i.e. IVIG), we sought to determine if unnecessary variation in drug use may be an opportunity to improve…2017 American Transplant Congress
Tocilizmab (Anti-IL-6R) Treatment (TCZ-Rx) Reduced Total IgG Levels Including Anti-HLA IgG: Analysis of IgG Subclasses (IgG1-IgG4) and Anti-HLA IgG Subclasses Show Similar Reductions in All Subclasses from Patients with DSA+ Chronic Antibody-Mediated Rejection (CABMR).
Background: DSA+ CABMR constitutes the major cause for renal allograft loss in the U.S. Currently there are no approved therapies. We have reported TCZ use…2017 American Transplant Congress
Hypogammaglobulinemia in Pediatric Heart Transplant Candidates Is Not Corrected by Transplantation.
Introduction: Hypogammaglobulinemia (HG) is associated with poor outcomes in adult heart transplant recipients but is not well studied in pediatric recipients. We therefore investigated longitudinal…2016 American Transplant Congress
Fc Receptor Binding Assay for Functional Assessment of HLA Antibodies: Initial Clinical Validation.
Functional assessment of HLA antibodies (Abs) has historically been limited to complement-based assays, which have known limitations. Moreover, HLA Abs mediate injury by complement-independent mechanisms,…2016 American Transplant Congress
VDJ Immune Repertoire Sequencing Predicts Patients at Risk of Alloimmune Injury.
1Surgery and Bioinformatics, UCSF, San Francisco, CA; 2Genetics, Stanford University, Palo Alto, CA.
Background: The complex repertoire of immune receptors generated by B cells enables allo-recognition in the context of transplantation across HLA barriers, and is a major…2016 American Transplant Congress
HLA Antibody Clonality and Epitopes Dictate Complement Activation.
Background: Alloimmunization results in production of polyclonal donor specific antibodies (DSA) against human leukocyte antigens (HLA), which mediate endothelial cell activation, leukocyte recruitment, and complement…
