A recent meta-analysis study, aimed to correlate ARDS/ALI with inflammatory factors, identified an association between this pathology and increased levels of Angiopoietin 2 (ANG-2), IL-1β, IL-6 and TNFα, but not with IL-8, Interleukin-10 (IL-10) and Plasminogen activator inhibitor-1 (PAI-1) levels [5]. Here, ANGPT2 is linked to acute respiratory distress syndrome.
