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
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
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
Risk of HLA Antibody Sensitization in Pediatric Heart Failure Patients Pre/Post Berlin VAD Procedure and Pre/Post Heart Transplantation
Baylor College of Medicine, Houston, TX; Texas Children's Hospital, Houston, TX.
The Berlin Heart Excor Ventricular Assist Device (Berlin VAD) was designed for use in children with heart failure. The Berlin VAD has allowed for successful…2015 American Transplant Congress
Number of Antigen Targets: A Key Parameter for Accurate Flow Cytometry Crossmatch Interpretation of Weak DSA
BACKGROUND: Flow cytometry crossmatch (FCXM) results are used to assess the safety of a transplant across pre-existing DSA. The number of targets on donor cells…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…2015 American Transplant Congress
Outcome of Bortezomib/Plasmapheresis for the Sensitized Patient Awaiting Heart Transplant
Cedars-Sinai Heart Institute, Los Angeles, CA.
Purpose: Allosensitization of patients (pts) awaiting heart transplantation is a significant challenge as it prolongs the time to transplant, increases wait-list mortality and increases risk…2015 American Transplant Congress
Bortezomib Treatment in Antibody Mediated Rejection After Kidney Transplantation
BackgroundSeveral studies demonstrated bortezomib therapy for antibody-mediated rejection (AMR) in renal transplants. However, the treatment efficacy according to target antigen or occurrence time of AMR…
