Intravenous Immunoglobulins and Methylprednisolone Stabilizes Renal Allograft Function in the Majority of Patients with C-aABMR
Erasmus Medical Center, Rotterdam, Netherlands.
BackgroundChronic active antibody mediated rejection (c-aABMR) leads to progressive decline in allograft function and is a major contributor to long-term kidney allograft loss. To date,…2018 American Transplant Congress
The Impact of Lymphocele Formation after Kidney Transplantation on De Novo Donor Specific Antibody Formation
Introduction: Lymphocele formation is a common complication after kidney transplantation and has been linked to rejection episodes. However, long-term outcome data are scarce and the…2018 American Transplant Congress
Impact of De Novo DSA Development and Management on Kidney Transplant Outcomes
Multiple studies have shown that development of donor specific antibodies (DSAs) can have a negative impact on renal allograft outcomes resulting in decreased renal function,…2018 American Transplant Congress
Noninvasive Quantization of Intra-Renal Allograft C4d Deposition with Targeted Ultrasound Imaging
Antibody-mediated rejection (AMR) has emerged as the major cause of renal allograft dysfunction. C4d, a specific marker of AMR diagnosis, was strongly recommended for routine…2018 American Transplant Congress
Depletion Resistant Effector Memory T Cells Mediate Thymoglobulin Refractory Allograft Rejection in Human Intestinal Transplant Recipients
Medstar Georgetown Transplant Institute, Medstar Georgetown University Hospital, Washington, DC.
A. This study aimed to determine the mechanisms underlying T cell depletion-resistant moderate to severe acute cellular rejection (ACR) in intestinal transplantation (ITx) patients.B. A…2018 American Transplant Congress
Precision Medicine for Determining the Efficacy of a Novel Belatacept Regimen
Transplant Nephrology, UCSF, San Francisco, CA.
IntroBelatacept is increasingly used as maintenance immunosuppression to improve long term outcomes in kidney transplant. Since acute rejection in patients on belatacept have been noted…2018 American Transplant Congress
“Majority Rules”: A Method to Reduce Variability in Diagnosing Antibody Mediated Rejection in Renal Allograft Biopsies Using Banff 2013
1Mayo Clinic, Rochester, MN; 2Mayo Clinic, Scottsdale, AZ; 3Mayo Clinic, Jacksonville, FL.
Introduction: The Banff 2013 criteria for diagnosing antibody-mediated rejection (ABMR) includes three lesions: glomerulitis (g), peritubularitis (PTC), and chronic glomerulopathy (cg). The poor reproducibility of…2018 American Transplant Congress
Donor-Specific Antibody Mediates Chronic, but Not Acute, Kidney Allograft Rejection in the Absence of Natural Killer Cells
Immunology and Glickman Urological Institute, Cleveland Clinic, Cleveland, OH.
The incidence of antibody-mediated kidney graft rejection continues to increase. We previously reported that dysregulated donor-specific antibody (DSA) responses were induced in B6.CCR5-/- mice transplanted…2018 American Transplant Congress
Role of B Cell Intrinsic NLRP3 in the Development of Chronic Rejection
Endogenous DAMPs elicited during transplantation are recognized via TLR-MyD88 and NLRP3-inflammosome pathways that are expressed in APCs including B cells. Here, we asked whether B…2018 American Transplant Congress
Donor-Derived Cell-Free DNA Outperforms Serum Creatinine Changes for Identifying Kidney Transplant Rejection
Purpose: In the DART study, donor-derived cell-free DNA (dd-cfDNA) discriminated biopsy-based diagnosis of active rejection in kidney transplant patients but serum creatinine (sCr) level did…
