Compared with ordinary pneumonia patients, patients in the severe group presented with significantly higher white blood cell (WBC) count, neutrophil count, LDH, C-reactive protein (CRP), SAA, high-sensitivity troponin T (HS-TnT), N-terminal pro-brain natriuretic peptide (NT-proBNP), D-dimer, and fibrinogen and lower albumin (p < 0.05 for all) (Table 1). This evidence concerns the gene CRP and susceptibility to pneumonia measurement.
