ABSTRACT
Acute respiratory distress syndrome (ARDS), a common respiratory critical illness with multiple causes, is associated with high mortality. The high degree of heterogeneity may be the reason why it is lack of highly specific and sensitive biological biomarkers. Therefore, it is an urgent need to explore biomarkers, perform phenotypic analysis and establish risk stratification model for diagnosis, prognosis, and treatment of ARDS. Endothelial cells specificity molecular-1 (ESM-1, endocan), is a soluble dermatan sulfate proteoglycan, and be involved in regulating biological behaviors such as cell proliferation, differentiation and migration. Numerous studies have confirmed that ESM-1 is closely related to inflammation, endothelial activation and dysfunction. However, the role of ESM-1 in the initiating and developing process of ARDS is still unclear. To provide a scientific basis for its clinical applications in ARDS, such as early prognosis assessment and timely prevent strategies, this paper focuses on the biological properties and the clinical value of ESM-1 as a potential biomarker for ARDS.
