Title: Clinical value of serum procalcitonin in diagnosis and treatment of community acquired pneumonia
Abstract: Objective To detect the level of serum procalcitonin(PCT)in the patients with community acquired pneumonia(CAP),and to clarify its significance in diagnosis and treatment of CAP.Methods 127 CAP patients and 30 cases of normal individuals were selected.According to the sputum bacterial culture results,127 CAP patients were divided into positive bacteria culture group(n=54)and negative bacteria culture group(n=73);according to the diagnostic criteria of severe pneumonia,the bacteria culture positive group was divided into severe pneumonia group(n=13)and non-severe pneumonia group(n=41).The levels of serum PCT,the white blood cell(WBC)count,neutrophil percentage(NEUT%)and levels of C-reactive protein(CRP)of the objects were detected by double antibody sandwich method.Results After treated for 8d,the levels of serum PCT of the objects in positive bacteria culture group and negative bacteria culture group and normal control group had no significant differences.After treated for 8d,the levels of serum PCT of the objects in positive bacteria culture group and negative bacteria culture group were lower than that of the objects on the first day after treatment.The level of serum PCT of the patients in severe pneumonia group was significantly higher than that in non-severe pneumonia group;the WBC count,NEUT% and CRP level of the patients in severe pneumonia group were higher than those in non-severe pneumonia group,but the difference was not statistically significant.When consindering the bacterial culture as the gold standard for diagnosis of bacterial infection,the sensitivity and specificity of the serum level in diagnosis of bacterial CAP were superior to NEUT% and WBC count.Conclusion The level of serum PCT plays a role in the diagnosis of CAP,and it could help to judge whether the CAP patient gets a bacterial infection and assess the severity of pneumonia and the discontinuation of antibiotics.
