Three Year Outcomes Following Positive Crossmatch Renal Transplantation Despite Failure to Convert to Negative Flow Crossmatch After Desensitization.
Purpose: To determine outcomes of positive crossmatch (PXM) renal transplant recipients that failed to convert to a negative flow cytometry crossmatch (FCXM) despite desensitization. Methods:…2017 American Transplant Congress
IgG Antibody Subclasses in Potential Renal Transplant Recipients with DSA, AHG-CDC CxM Negative and FxM Positive or Negative with Their Potential Donors.
Background. In kidney transplant recipients, IgG3 and IgG4 DSA have been associated with shorter time to acute AMR and with later allograft injury (glomerulopathy &…2017 American Transplant Congress
C3d Assay Result in Potential Transplant Recipients with HLA-DSA, AHG-CDC CxM Negative and FxM Positive or Negative with Their Potential Donors.
Background: In a previous study we searched the association between the flow cytometry cross-match assay (FXM) result and the results obtained in the analysis of…2017 American Transplant Congress
False-Positive Flow Cytometric Crossmatch Results and the Utility of the Virtual Crossmatch.
Pathology, University of Chicago Medicine, Chicago, IL
Introduction: A negative crossmatch (XM) is critical for solid organ allocation. Flow cytometric XM (FCXM) is more sensitive than complement-dependent cytotoxicity XM (CDC-XM), and has…2017 American Transplant Congress
Prediction of Positive Cytotoxic and Flow Crossmatches for Sensitized Wait List Candidates: Comparison of Luminex MFI, C1q and FcR Binding Assays.
Surgery, University of Cincinnati, Cincinnati
Clinical relevance of HLA antibodies identified in solid phase assays includes their ability to generate a positive crossmatch (XM) test, which often precludes transplantation. The…2017 American Transplant Congress
Clinical Impact of Strength and Class of Pre transplant Donor Specific Antibody on Kidney Transplant Recipient Receiving Steroid Free Maintenance Immunosupression Regimen.
Renal Transplant, Indiana University School of Medicine, Indianapolis, IN
Background: The class and strength of pre- transplant DSA has been described as playing a role in determining future risk of acute rejection (AR) and…2017 American Transplant Congress
Pre Transplant Donor Specific Antibodies and Clinical Outcomes in Kidney Transplant Recipient on Steroid Free Maintenance Immunosupression Regimen.
Background: The clinical relevance of pre transplant donor specific antibodies has been reported in few clinical studies with respect to its effect on the risk…2016 American Transplant Congress
Positive Lymphocytes Flow Cytometry Crossmatch Due to AT1r Antibodies in Absence of HLA-DSA.
The angiotensin II type 1 receptor (AT1r) plays a key role in the renin-angiotensin system. Anti-AT1R antibodies (Abs) have been associated with both acute and…2016 American Transplant Congress
Blocking Fc Receptor in Flow Cytometric Crossmatch: Refining an Old Assay to Improve Patient Management.
Pathology, University of Chicago, Chicago, IL.
Introduction: The crossmatch assay is used to determine sensitization of solid organ transplant recipients to donor-expressed HLA molecules, a potential contraindication to transplant. Multicolor flow…2016 American Transplant Congress
Optimized Flow Cytometry Crossmatch with Increased Sensitivity and Specificity.
The flow cytometry crossmatch (FCXM) is the standard method to prevent hyperacute rejection after transplantation. Surprisingly, few technical improvements have been introduced to the FCXM…
