In the TBI group, all blood inflammatory markers (procalcitonin (PCT), C-reactive protein (CRP) and counts of white blood cells (WBCs) and neutrophils (NEUs)) were present at higher levels in the patients with ALI than in those without ALI (p < 0.05); however, no such difference was observed in the MPT group. The gene discussed is CRP; the disease is acute respiratory distress syndrome.
