On hospital admission, the ARDS group showed significantly higher levels of white blood cell (WBC) (p=0.0032) and neutrophils (p=0.0036) absolute counts, neutrophils/lymphocytes ratio (NLR) (p=0.0010), CRP (p=0.0436), ferritin (p=0.0026), LDH (p<0.0001), and IL-6 (p<0.0001) compared to non-ARDS group (Table 1). This evidence concerns the gene IL6 and acute respiratory distress syndrome.
