[Research Progress in Diagnosis and Treatment of Acute Leukemia Complicated with Pulmonary Infection--Review].

Acute leukaemia is a group of aggressive malignancies with a high mortality rate. The reduction in functional immune cells due to the disease itself and radiotherapy/chemotherapy makes the patients susceptible to co-infections, of which pulmonary infection is a major cause of death. Early accurate diagnosis and appropriate treatment may prevent the spread of infection in patients with acute leukaemia complicated with pulmonary infection, thus reduce serious complications such as sepsis, respiratory failure and multi-organ failure. However, there are still clinical difficulties in the diagnosis and treatment of pulmonary infections in acute leukemia patients. Therefore, the current research advances in the diagnosis and treatment of bacterial, fungal and viral infections in the lungs of patients with acute leukemia were briefly summarized in this review.
