Overexpression of anti-apoptotic protein BCL-2 and hypermethylation are hallmarks of acute lymphoblastic leukemia (ALL) and can be pharmacologically addressed by venetoclax (VEN) and hypomethylating agents (HMA) such as azacytidine (AZA) or decitabine (DEC). AZA-induced metabolic suppression as well as overall anti-leukemic activity alone and in combination with VEN was generally weaker compared to DEC. Altogether, we herein demonstrate that combined VEN and HMA application acts synergistically and significantly reduces the leukemic burden in ALL cell lines via impairment of tumor cell metabolism and mitochondrial function.
Azacitidine was administered after dialysis sessions, while venetoclax dosing was adjusted because of concomitant posaconazole prophylaxis. Approximately one year after diagnosis, relapsed AML was identified on peripheral blood flow cytometry. This case highlights the feasibility of venetoclax-based lower-intensity therapy in selected dialysis-dependent AML patients while underscoring the persistent therapeutic limitations and adverse prognosis associated with relapsed disease in this population.

Based on treatment regimens, the patients were categorized into chemotherapy group ("3+7"regimen), demethylation therapy (HMA) group (decitabine-based therapy), and UCB group (venetoclax combined with azacitidine plus UCB reinfusion). Cytokine level analysis demonstrated that the direct co-culture group showed higher levels of TNF-α and IFN-γ, as well as lower levels of IL-6 compared to the control group (P<0.001). Immunocytes such as NK cells in UCB may promote immune function reconstruction and hematopoietic recovery in patients, thereby improving their prognosis.
