HLA Epitopes and Shared Molecular Eplet Characterization and Their Implication on Transplant Outcome: The Experience of One Center.

We report three interesting cases concerning antibody-mediated rejection (AMR), associated or not with anti-donor-specific antibodies, and detection of implicated molecular epitopes. The first report presents a case of intra-allele sensitization. The second case presents an interesting case concerning Luminex mean fluorescence intensity (MFI) levels considered to be low risk antibodies (<1000), but producing AMR. The third case occurred after a second kidney transplantation mediated by antibodies directed against HLA-C antigens (MFI<1000) in the previous transplantation (which was considered to be an indicator of low-risk of AMR).
