Moreover, the patients with pneumonia had higher platelet counts; higher serum activities of gamma-glutamyl transpeptidase (GGT) and lactate dehydrogenase (LDH); longer prothrombin times; higher serum concentrations of IL-6, ferritin, PTX-3, and galectin-3; and lower serum albumin, total protein, and high-density lipoprotein (HDL) cholesterol (Table 3). This evidence concerns the gene PTX3 and susceptibility to pneumonia measurement.
