PROTOCOL OUTLINE:
This is an observational study. The blood and BALF samples will be collected from patients with ARDS for exosome extraction and transcriptome and metabolomic analysis.
Exosome characterization and differential genes and metabolites will be identified.

Identification of ARDS Endotypes
Tidsramme: 2 years
|
Blood samples will be collected on day 1, 3, 5,7 since ARDS diagnosis is made (day 0) and BALF samples will be collected on day 1 and day 7. Blood samples are used to extract PBMC and BALF samples are used to extract alveolar macrophage.
Afterwards, PBMC and alveolar macrophage are saved for further transcriptomic and metabomic analysis.
At the same time, clinical and biological date are collected to identify subgroups of patients that might share mortality risk, clinical course, and/or treatment responsiveness.
At last, the relationship between transcriptomic and metabomic signature of PBMC and alveolar macrophage and the clinical phenotypes are analyzed to determine ARDS endotypes.
