Brief summary
Sepsis-induced acute respiratory distress syndrome (ARDS) is a life-threatening acute inflammatory lung injury, associated with increased pulmonary microvascular permeability, increased lung weight, and loss of aerated lung tissue.Despite advances in critical care, no established and targeted treatment for ARDS, contributing to a persistently high mortality rate of 34% to 45%. Therefore, exploring novel therapeutic targets for septic ARDS is of paramount importance.Acetaldehyde dehydrogenase 2 (ALDH2) is a mitochondrial enzyme that serves as the primary toxic aldehyde scavenger and is expressed in various cells, including neutrophils. The ALDH2 rs671 single nucleotide polymorphism, leading to an approximate 90% decrease in ALDH2 enzymatic activity, is implicated in occurrence of macrovascular conditions, such as coronary artery disease, pulmonary arterial hypertension, and aortic aneurysm or dissection.An array of studies has delved into role of ALDH2 in regulating cellular processes, including inflammation, autophagy, apoptosis, necrosis,efferocytosis and pyroptosis.but whether it associated with the incidence of septic-ARDS remains unknown.The aim of this study was to determine whether the ALDH2 rs671 single nucleotide polymorphism was associated with the incidence of septic-ARDS.

Inclusion criteria
Patients admitted to the ICU who were aged 18 to 85 years with a diagnosis of sepsis.Sepsis was assessed according to the third international consensus definition as life-threatening organ dysfunction caused by a dysregulated host response to infection; organ dysfunction was defined as an acute change in total Sequential Organ Failure Assessment (SOFA) score of ≥2 points consequent to the infection.
Exclusion criteria
1. interstitial lung disease, chronic obstructive pulmonary disease or congestive heart failure; 2. nerve injury or disease with likely prolonged ventilation； 3. the use of long-term oxygen therapy or noninvasive ventilation at home; 4. pregnancy or breastfeeding.
