Biomarkers of inflammation in acute lung injury and acute respiratory distress syndrome. Comparison of plasma levels of biomarkers of inflammation in 50 patients with acute lung injury and acute respiratory distress syndrome ventilated with low-tidal-volume ventilation. Plasma levels of (a) IL-8 and (b) soluble intercellular adhesion molecule 1 (sICAM-1) were significantly higher in nonsurvivors than in survivors. Data shown as boxplots: horizontal line, median; box, 25th to 75th percentiles; error bars, 10th to 90th percentiles. *P = 0.002 and **P = 0.006 compared with survivors, Mann–Whitney U test.
