a (Left) 16S rRNA copy numbers from the BALF of ARDS patients were increased compared with the controls. (Right) 16S rRNA copy numbers from the BALF did not significantly differ between the BP and non-BP among ARDS. We compared the 10 patients with bacterial pneumonia to 30 patients with non-bacterial pneumonia. b Serum and BALF cytokine levels including IL-6, IL-8, RAGE and Ang-2 were compared between surviving and non-surviving ARDS patients. Serum IL-6 levels in 22 survivors were significantly increased compared with those of 13 non-survivors (*P < 0.05). We collected blood samples within 24 h after obtaining the BALF in 35 of ARDS patients. BALF cytokine levels were measured in 23 survivors and 15 non-survivors. ARDS, acute respiratory distress syndrome; BP, bacterial pneumonia; IL, interleukin; RAGE, receptor of advanced glycation end-products; Ang-2, Angiopoietin-2
