Patients with concurrent acute myeloid leukemia (AML) and active pulmonary tuberculosis (TB) exhibit certain characteristics; cough, phlegm, fever, hemoptysis, weight loss and dyspnea are common symptoms of both diseases. These patients often cannot tolerate traditional intensive chemotherapy regimens, and finding the optimal timing in the treatment of both AML and active pulmonary TB is complex. Neglecting timely treatment can lead to serious complications and even fatal outcomes. The present paper reports two cases of patients with AML who were diagnosed with active pulmonary TB. The patients received intensive anti-TB treatment with isoniazid, rifampicin, pyrazinamide and ethambutol for 10-15 days. After three consecutive negative sputum smears, the patients in cases 1 and 2 were treated with a venetoclax, homoharringtonine and cytarabine regimen; and a venetoclax and azacitidine regimen for anti-AML therapy, respectively, as well as individualized anti-TB regimens of isoniazid, pyrazinamide, ethambutol and quinolone. Subsequently, both patients achieved complete remission of AML and their active TB was well controlled.
