Abstract: Methods and systems for desensitizing a human leukocyte antigen (HLA) sensitized subject to prepare for an organ transplant with an improved transplant survival and function, and/or treating or reducing the likelihood of antibody mediated rejection (ABMR) of an organ transplant in a subject are provided, generally including administering an effective amount of an anti-CD38 antibody or a CD38-targeting therapy to reduce the symptoms or ABMR or HLA levels. The subject in the methods may have developed or is experience drug-resistant sensitization, and to whom standard techniques like intravenous immunoglobulin and plasmapheresis are ineffective.

Abstract: An intracellular cytokine flow cytometry (CFC) assay was developed to measure CD3? (non-T) cell response to allo-Ags expressed on peripheral blood mononuclear cells (allo-CFC-PBMC) and/or endothelial cells (allo-CFC-EC) by detecting intracellular gamma-interferon (IFNY) production. The assay can be used to determine a likelihood of antibody mediated rejection in an individual. A method for using genetic screening to determine the likelihood of AMR is also disclosed.

Abstract: The present invention is directed to assays that may be used to measure B cell reactivity to allo or donor antigens in patients, gauge the efficacy of desensitization treatment of these individuals, predict antibody mediated rejection, and monitor patients post transplant for antibody mediated rejection.
