Objective: To investigate the serum inflammatory cytokines expression in different pathogens and to explore the value of serum inflammatory cytokines in judging the severity of disease and assessing prognosis. Methods: We retrospectively analyzed 90 cases of bloodstream infections admitted to our hospital from October 2016 to November 2017 and regarded it as observation group, while the control group was 80 patients with negative blood cultures over the same period. Serum inflammatory factors PCT, C-reactive protein (CRP), white blood cell count (WBC), neutrophil percentage (NEUT) and Endotoxin levels were compared between the two groups.The levels of serum inflammatory factors PCT, CRP, WBC, NEUT and Endotoxin in patients with Gram-positive(G+), Gram-negative (G-), treatment improvement and treatment ineffective group were compared. Result: The levels of PCT, CRP, WBC, NEUT and Endotoxin in patients with positive blood flow culture were significantly higher than those with negative blood culture. Compared with the G+ group, the levels of PCT, CRP, WBC and Endotoxin in the G- group were significantly higher. There was no significant difference in the level of NEUT in two groups. Compared with the treatment-ineffective group, the therapeutic improvement group PCT, CRP, WBC, NEUT and Endotoxin levels decreased significantly. The levels of PCT, CRP, WBC,NEUT and endotoxin in patients with moderate and severe bloodstream infections were significantly higher than those with mild infections;the levels of PCT, CRP, WBC, NEUT and endotoxin in patients with moderate infection were significantly higher than those with mild infections, and all has statistical significance. Conclusion:PCT, CRP, WBC, NEUT and Endotoxin can be used as auxiliary diagnostic indicators of bloodstream infections, which can be used to judge the severity of bloodstream infection and evaluate the prognosis.
