Figure 1 White blood cell count (WBC), platelet count (PLT), C-reactive protein (CRP), and creatinine levels for all patients at admission to the hospital. Creatinine levels in men were higher (median 1.68 mg/dL; range 0.77–16.81 mg/dL) than in women (median 1.47 mg/dL; range 0.59–9.22 mg/dL); this difference was statistically significant (P=0.0463). No statistically significant difference was observed between values of biochemical parameters (WBC, CRP, PLT levels) between women and men. Higher creatinine values were observed in patients with blood extended-spectrum beta-lactamase (ESBL)-positive isolates (median 1.75 mg/dL) than in patients with blood ESBL-negative isolates (median 1.44 mg/dL), and this difference was statistically significant (P 0.02). The other values for WBC, CRP, and PLT did not differ significantly in patients with sepsis caused by ESBL-positive and other isolates (Enterobacteriaceae ESBL-negative and other strains).
