Acute myeloid leukemia (AML) patients suffering from relapse after allogeneic hematopoietic cell transplantation (allo-HCT) have a poor survival outcome. Donor lymphocyte infusions (DLIs) to induce graft-versus-leukemia (GvL) effects have a limited survival benefit.~Extensive preclinical studies have shown a beneficial effect of sodium bicarbonate on metabolic fitness of leukemia-reactive T cells in GvL AML models. Therefore, the investigators aimed to investigate a potential benefit of Bicanorm (Sodium bicarbonate) treatment accompanying DLIs in relapsed AML patients. The investigators determined the metabolic and immune phenotype of T cells isolated from patients receiving DLIs before and after Bicanorm (Sodium bicarbonate) treatment.
In this study, the outcomes of relapsed AML patients receiving DLIs and Bicanorm (Sodium bicarbonate) were analyzed including T cell metabolism and immune phenotype.
