Abstract:
Objective:To evaluate the prognostic value of combined detection of serum C-reactive protein(CRP), procalcitonin and lactic acid in elderly patients with community acquired pneumonia(CAP).Methods:Ninety-five elderly CAP patients in the emergency department of Shangqiu First People's Hospital were included as the case group, and 45 elderly healthy people in the emergency department of Shangqiu First People's Hospital were enrolled as the control group.Levels of blood lactic acid, procalcitonin and CRP were compared between the two groups.Meanwhile, blood levels of lactic acid, procalcitonin and CRP were compared between patients with different outcomes in the case group.The receiver operating characteristic(ROC)curve was used to evaluate the prognostic value of CRP, procalcitonin and blood lactic acid in elderly patients with CAP.Results:Compared with the control group, blood levels of lactic acid, procalcitonin and CRP were increased in the case group( t=20.77, 26.03 and 31.27, all P<0.01). During a 12-month follow-up, 13 cases(13.68%, 13/95)died and 82 cases(86.32%, 82/95)survived in the case group.Blood levels of lactic acid, procalcitonin and CRP were higher in the death group than in the survival group( t=25.56, 8.30 and 13.56, all P<0.01). ROC curve analysis showed that the sensitivity and specificity of serum lactic acid, procalcitonin and CRP in predicting the prognosis of elderly CAP patients were 76.92% and 73.17%, 84.62% and 78.05%, and 69.23% and 70.73%, respectively.The sensitivity and specificity of combined detection of the three indicators were 92.31% and 89.02%, respectively, higher than those of the individual indicators. Conclusions:Serum levels of lactic acid, procalcitonin and CRP are increased in elderly patients with CAP.Combined detection of the three indicators can improve the prognostic value and therefore has important clinical significance.
