Circulating Follicular Helper T Cells (cTfh) in Renal Transplantation: Utility as Rejection Biomarker
Introduction: Antibody (Ab) mediated rejection is responsible for 30-50% of renal graft failures. Follicular helper T cells (Tfh) are required for the differentiation of B…2018 American Transplant Congress
NKG2C+CD57+ NK (G2C+57+) Cells Expanded by CMV Infection Are Highly Responsive to Allo-Antibody (Ab)-Mediated NK Cell Stimulation
Introduction: Active CMV infection is known to be associated with risk for ABMR in allograft recipients. Ab-dependent cellular cytotoxicity (ADCC) primarily mediated by NK cells…2018 American Transplant Congress
Association between Genetic Polymorphisms of Fc Gamma Receptor Genes (FcgR) and the Development of Donor Specific Antibodies (DSA) after Kidney Transplant
Background: Antibody mediated rejection (AMR) is one of the most important barriers to improve long-term kidney transplant outcomes. The presence of donor specific antibodies (DSA)…2018 American Transplant Congress
CTLA4-Ig and Bortezomib Successfully Reverses Established DSA Responses in Allograft-Sensitized Recipients
Background: Sensitized recipients have lower rates of transplantation and poorer outcomes. We and others have reported that the delayed administration of CTLA4-Ig can disrupt fully-established…2018 American Transplant Congress
The Likelihood of Re-Transplantation in Patients Undergoing Allograft Nephrectomy
Introduction: transplant nephrectomy (NX) is a known cause of allosensitisation after graft failure. As yet, there is no consensus for the management of the patient…2018 American Transplant Congress
Pre-Transplant versus De Novo Donor Specific Antibodies: Differences in Clinical Outcomes and Antibody Mediated Rejection
Montefiore-Einstein Transplant Center, Montefiore-Einstein Transplant Center, Bronx.
Background: Antibody mediated rejection (ABMR) can occur through pre-transplant(tx) vs. de novo donor specific antibodies (DSA). Clinical outcomes, allograft injury and dynamics of DSAs have…2018 American Transplant Congress
Urinary Tract Infections May Be Associated with De Novo Donor-Specific Anti-Human Leucocyte Antigen Antibodies: Single-Center Study
Introduction: We have recently shown that immunosuppression reduction with BK virus is associated with the development of de novo donor anti-human leukocyte antigen-specific antibodies (dnDSA).…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
Circulating Wnt Pathway Factors Are Non-Invasive Biomarkers of Transplant Vascular Injury
Purpose: Transplant vascular injury (TVI) is a major cause of renal allograft failure and is resistant to treatment. Non-invasive pathogenic biomarkers of TVI would provide…2018 American Transplant Congress
Sub-Clinical Acute Rejection (subAR) Detected by Both Surveillance Biopsy (SBx) and a Peripheral Blood Molecular Biomarker Correlates with De Novo Donor Specific Antibody (dnDSA) Following Kidney Transplant (KT)
AIMWe investigated the correlation between subAR diagnosed by SBx or by a newly-defined biomarker, and the development of dnDSA.METHODS307 KT patients enrolled into a multi-center…
