Distinct Subtypes of Rejection in a Novel Non Human Primate Model of Sensitization
[Background] Preformed and newly formed alloantibody post transplantation (TX) can significantly deteriorate graft survival. Patterns of humoral rejection in sensitized patients varies significantly due to…2015 American Transplant Congress
Blocking CD4 T Cell Helper Functions Improves Efficacy of ATG Treatment in Sensitized Transplant Recipients
Immunology, Cleveland Clinic, Cleveland, OH.
Antibody mediated lymphocyte depletion is used in clinical transplantation to improve graft function. While the presence of donor-reactive memory T cells is the primary rationale…2015 American Transplant Congress
Combined Anti-IL6R and CTLA4Ig Therapy Attenuates Recall Alloantibody Responses in a Mouse Model of HLA Sensitization
Comprehensive Transplant Center, Cedars-Sinai Medical Center, Los Angeles, CA.
[bald]Background[/bald] We previously reported that IL-6 inhibition by anti-IL6R antibody (mMR16-1) or CD28 pathway inhibition using CTLA4Ig (abatacept) reduced recall alloantibody responses in a mouse…2015 American Transplant Congress
Differential Clinical Outcomes in Kidney Transplant Recipients With De Novo C1q+ and C1q- Donor Specific Antibodies
Background: We investigated the prevalence and clinical significance of C1q binding versus non-C1q binding de novo DSA in kidney transplant recipients.Methods: The study group included…2015 American Transplant Congress
The Use of Bortezomib for Desensitization in ABO Incompatible and Positive Crossmatch Kidney Transplant
Introduction:ABO incompatible (ABOi) and positive crossmatch (PXM) living donor kidney transplantation is a life-saving alternative to dialysis. A variety of protocols exist utilizing plasmapheresis (PP)…2015 American Transplant Congress
Costimulation Blockade and Bortezomib to Desensitize Rhesus Macaque and Prolong Renal Allograft Survival
Surgery, Emory Transplant Center, Atlanta, GA.

Desensitization Before Living Donor Kidney Transplantation in Highly Sensitized Patients
Renal transplantation in highly sensitized patients represents a major clinical challenge leading to long periods in the waiting list. When a living donor is available,…2015 American Transplant Congress
A Prospective Pilot Study Evaluating the Safety and Efficacy of Everolimus for the Prevention of CMV and BK Viral Infection (BKV) in Broadly Sensitized Kidney Transplant Recipients Following Desensitization With IVIG and Rituximab: Interim Analysis
Introduction: Everolimus, a second generation mTOR inhibitor, may prevent CMV and BKV infection after kidney transplantation. Broadly sensitized patients are at greater risk of viral…2015 American Transplant Congress
Rituximab With Intravenous Immune Globulin in Sensitized Patients Awaiting Heart Transplant: Does It Work?
Cedars-Sinai Heart Institute, Los Angeles, CA.
Purpose: Highly sensitized heart transplant (HTx) recipients with donor specific antibodies (DSA) are at increased risk of rejection and death. Rituximab with Intravenous Immune Globulin…2015 American Transplant Congress
The Differential Effect of HLA-DQ Mismatching on Renal Allograft Survival in Zero HLA-A,B,DR Mismatched Deceased Donor Transplants
1University of Florida, Gainesville; 2University of Kansas, Kansas City.
