De Novo Donor-Specific HLA Antibodies After Kidney Transplantation Are Associated With Donation After Circulatory Death and HLA-DQ Mismatch
Introduction: De novo donor-specific HLA-antibodies (dnDSA) have been associated with rejection and inferior kidney graft survival. The purpose of this study was to investigate the…2015 American Transplant Congress
Clinical Significance of Estimated DSA MFI Values at 1,000 C1q MFI for Differentiation Between Harmful and Harmless DSA
INTRODUCTIONControl of chronic antibody mediated rejection (CAMR) is essential for further improvement of long-term graft survival. Early detection of de novo donor specific antibodies (DSA)…2015 American Transplant Congress
Impact of Positive Crossmatch Due to Non-HLA Antibodies on Graft Outcomes in Renal Transplantation
Houston Methodist Hospital, Houston, TX.
It is widely recognized that a positive allogeneic crossmatch (+alloXM) due to pre-existing human leukocyte antigen (HLA) antibodies is associated with early rejection episodes. However,…2015 American Transplant Congress
Clinical Relevance of C3d-Binding Donor-Specific Antibodies in Late Kidney Allograft Failure
Background: The objective of this study was to investigate the prognostic value of C3d-binding donor-specific antibodies (DSA) in determining late kidney allograft failure.Methods: 1048 patients…2015 American Transplant Congress
Repeat Donor HLA Mismatch Antigens and Kidney Transplant Outcome
Background: Historically, poorer outcome has been reported in kidney re-transplant patients with repeat HLA mismatch antigens. Transplant practice has evolved. Risk of repeat mismatch antigen…2015 American Transplant Congress
Measuring Affinity of Polyclonal HLA-Specific Antibodies in Highly Sensitised Cases Can Serve as an Additional Biomarker to Guide Direct Transplantation
Significant numbers of patients on transplant waiting lists in the UK are sensitised (43%). Direct transplantation across these HLA-specific antibodies using risk stratification strategies are…2015 American Transplant Congress
The Correlation Between Donor Specific Antibodies and Heart Transplant Rejection
The presence of donor specific HLA antibodies (DSA) has been shown to be detrimental to heart transplant (HTx) survival. Virtual crossmatching (VXM) offers a rapid…2015 American Transplant Congress
Assessment of Circulating HLA-Specific Alloreactive Memory B Cells Reveals Surreptitious Immunized Kidney Transplant Recipients at High Risk of Antibody-Mediated Rejection
Even though current bead-based multiplex techniques enable an accurate assessment of circulating HLA-specific antibodies, a more comprehensive study of the humoral alloimmune response through the…2015 American Transplant Congress
DQB1 Epitope Matching Predicts the Development of De Novo DSA and Antibody Mediated Rejection
HLA DQ antibodies are the commonest de novo [DN] DSA specificity seen post renal transplantation. Their presence is associated with antibody mediated injury and allograft…2015 American Transplant Congress
Improving the Predictive Value of the Virtual Crossmatch: Is the C1Q Assay Needed?
The criteria for reporting unacceptable HLA antigens of renal transplant candidates differ greatly between transplant centers. In the attempt to refine these criteria, the experience…
