GSTM1 and Sepsis: Table 3 demonstrates the comparative results of laboratory variables associated with sepsis in severe burns. Compared with nonsepsis patients, the serum expressions of TNF-α (P = 0.012), PCT (P < 0.001), and CAR (P < 0.001) at admission were significantly higher in sepsis patients. The levels of Hb, Plt, WBC, Hct, creatinine, and BUN did not differ significantly between these two groups (P > 0.05).
