Effective identification of HLA specificities to which a prospective transplant recipient has antibodies depends on how effective the most sensitive assay is in detecting these antibodies. To ascertain the assay's efficacy, the results of antibody screening of patients on the waiting list for a second transplant were studied. A commercially available panel of fluoro-coded microbeads coated with...

INTRODUCTION Precise and timely detection of human leukocyte antigen (HLA) donor-specific antibodies (DSAs) is vital for evaluating humoral immune status of patients pre- and post-transplantation. SOURCE OF DATA Clinically relevant articles on theory, development, methodology and application of HLA-DSA testing in kidney transplantation. AREAS OF AGREEMENT AND CONTROVERSY The availability of...

BACKGROUND Although HLA-C matching is not considered in kidney transplantation, several reports have shown that anti-HLA-C antibodies are associated with rejection and graft failure. DNA-based typing methods can now accurately determine HLA-C compatibility and sensitive assays such as Luminex with single alleles can identify HLA-C antibodies. HLA-C displays considerable amino acid polymorphism ...

Multi-center kidney paired donation (KPD) is an exciting new transplant option that has not yet approached its full potential. One barrier to progress is accurate virtual crossmatching for KPD waitlists with many highly sensitized patients. Virtual crossmatch results from a large multi-center consortium, the National Kidney Registry (NKR), were analyzed to determine the effectiveness of flexibl...

Autoimmune neutropenia (AIN) of early childhood is caused by autoantibodies against antigens on the neutrophil membrane. Human leukocyte (HLA) have previously been associated with AIN. This study investigated HLA-DRB1 and HLA-DQB1 alleles in 160 antibody positive patients compared 1000 controls. Increased risk was observed for DRB1*10, DRB1*14, DRB1*16 DQB1*05, lower DRB1*04, DRB1*13 DQB1*03. H...

BACKGROUND HLA Matchmaker is a computer algorithm developed to evaluate donor/receptor compatibility comparing sequences of polymorphic aminoacids (eplets) present in human leukocyte antigen (HLA) molecules. The aim of this study was to evaluate the predictive value of HLA Matchmaker for patient and graft survival, graft survival free of rejection, and the presence of anti HLA antibodies. MET...

The aim of this study was to determine the frequency and specificity of HLA-A and B antibodies in multiparous mothers in the Malaysian population. 1,100 maternal serum samples obtained during normal childbirth were screened against a panel of 100 lymphocytes with known HLA antigen types for HLA antibodies by the complement dependent lymphocyte microcytotoxicity dye exclusion test. From the tota...

The introduction of very sensitive HLA antibody screening assays has destroyed the old dogma that pre-existence of donor specific HLA antibodies in the patient is a contraindication for transplantation. The challenge is now to reach consensus on the parameters which predict the clinical relevance of donor specific HLA antibodies. Antibody screening assays should not only be used to prevent tran...
