Acute Myeloid Leukemia
Conditions
Brief summary
This is a prospective single-arm clinical study to evaluate the role of NAC after chemotherapy among patients with AML can promote hematopoietic recovery and does not affect the remission rate of the leukemia.
Detailed description
Hematopoietic recovery after chemotherapy is an important factor affecting the prognosis of acute myeloid leukemia. A previous clinical prospective cohort study showed that NAC could improve the function of bone marrow endothelial progenitor cells after chemotherapy, without affecting leukemia cells. Previous animal models have found that chemotherapy can reverse the function of bone marrow endothelial cells in classic AML mice. NAC promotes hematopoietic recovery in AML mice by improving the bone marrow endothelial cells reversed by chemotherapy. Therefore, we hypothesized that the prophylactic administration of NAC after chemotherapy could facilitate the recovery of hematopoietic capacity by improving the bone marrow microenvironment of patients with AML.
Interventions
N-acetyl-L-cysteine (Yiweishi) capsules (Guangdong Renrenkang Pharmaceutical Industry) will be given orally 400mg three times a day from day 1 to day 28 after chemotherapy. In case of drug allergy such as nausea, vomiting, rash and bronchospasm, and disease relapse, to discontinue the drug immediately.
