[Biomarkers in acute lung injury].

Acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) is characterized by non-cardiogenic, acute and progressive respiratory failure mediated by a variety of injurious stimuli. ALI can progress to ARDS if an effective management is not taken. The mortality rate remains high due to the complex pathogenesis and ineffective management of ARDS. At present, effective treatment methods for ALI are not available and thus it is important to study the pathogenesis and early diagnosis of ALI. This article reviews some of the biomarkers associated with ALI, with a focus on early diagnosis and future studies.
