CRP and susceptibility to pneumonia measurement: Analyzing our database, we could observe that Acute Kidney Injury (p < 0.0001), Pneumonia (p = 0.0316), Oxygen Supplementation (p = 0.0052), and SOFA index (p = 0.0153) in addition to the increased levels of biochemical biomarkers Serum Ferritin Peak (p < 0.0001), D-Dimer Peak (p < 0.05), Gamma-glutamyltransferase (GGT) (p < 0.05), and C-Reactive Protein (CRP) (p < 0.0001) were significantly related to death (Table 2; Fig. 4).
