They found that plasma malignant brain tumors 1 protein (DMBT1) was elevated in early ARDS compared to no ARDS (mean plasma concentration 2160.50 ± 94.06 vs. 1752.60 ± 111.68 pg/mL, p < 0.05) and was higher in severe ARDS compared to mild ARDS (mean plasma concentration 2255.26 ± 143.00 vs. 2160.50 ± 94.06 pg/mL, p < 0.05). This evidence concerns the gene DMBT1 and acute respiratory distress syndrome.
