Abstract
Acute myeloid leukemia (AML) can result in acute respiratory failure (ARF) during the first days, requiring intensive care unit (ICU) admission in half the cases. We describe three leukemia-specific syndromes responsible for ARF: leukostasis, pulmonary leukemic infiltration (PLI) and acute lysis pneumopathy (ALP). We retrospectively analyzed clinical and laboratory data from 114 patients admitted to a medical ICU within 10 days after a diagnosis of AML. Respiratory events (REs) occurred in 95 patients and were leukemia-specific in 58 patients (61%). Day-28 mortality was 34.5% in patients with leukemia-specific REs (leukostasis, 41%; PLI, 23%; and ALP, 31%) and 48.6% in patients with other REs. By multivariate analysis, independent risk factors for death were age > 50 (odds ratio, 13; 95% confidence interval, 3-51), Eastern Cooperative Oncology Group (ECOG) status ≥ 2 (5.4; 1.8-17) and need for invasive mechanical ventilation (19; 5-75). Dexamethasone therapy was protective (0.26; 0.09-0.8), suggesting a role as a preventive treatment in patients with AML-related non-infectious pulmonary involvement.This publication has 35 references indexed in Scilit:
