To estimate the prognostic value of major eicosanoids in acute respiratory distress syndrome (ARDS).
Conducted a prospective study in ARDS patients
Measured plasma concentrations of thromboxane B2, 6-keto prostaglandin F1α, and leukotriene B4
Correlated eicosanoid concentrations with clinical severity indicators
Leukotriene B4 was significantly higher in arterial plasma compared to mixed venous plasma
Correlations found between leukotriene B4 levels and lung injury severity
Only leukotriene B4 predicted significant differences in patient outcomes, showing a steep gradient in nonsurvivors compared to survivors

Implication

This prospective study finds leukotriene B4 correlates with lung injury severity and outcomes in ARDS patients, suggesting its potential as a prognostic biomarker.
