Surprisingly, concentrations of TNFα, sTNFR-1 and CXCL8 in BALF of C-ARDS were significantly lower than in NC-ARDS (Table 3, Figures 5C–E), but significantly higher than in controls for sTNFR-1 and CXCL8 (Table 3, Figures 5D, E). This evidence concerns the gene TNF and acute respiratory distress syndrome.
