摘要
目的探讨白细胞(WBC)、C反应蛋白(CRP)、降钙素原(PCT)三项指标在预测婴幼儿肺炎病原学的指导价值。方法对986例0~3岁不同肺炎病原体感染患儿进行WBC、CRP、PCT测定,比较阳性比率。结果986例标本中,细菌性肺炎459例,病毒性肺炎280例。其中细菌性肺炎WBC、CRP、PCT阳性比例分别为47.9%、57.1%、85.2%,病毒性肺炎WBC、CRP、PCT阳性比例分别21.1%、7.1%、16.8%,两组比较,差异有统计学意义。WBC计数在细菌感染组中的灵敏度为47.9%,特异度为78.9%;CRP水平在细菌感染组中的灵敏度为57.1%,特异度为92.9%;PCT值在细菌感染组中的灵敏度为85.2%,特异度为83.2%。结论婴幼儿细菌性肺炎WBC、CRP、PCT水平均高于病毒性肺炎;WBC、CRP、PCT测定结果对临床合理应用抗生素有一定指导意义。
Objective To explore values of white blood cells ( WBC), C-reactive protein ( CRP), and procalcitonin (PCT) in predicting the pathogen of infant pneumonia. Methods A total of 986 infants with pneumonia were selected and grouped by pathogen, aU of whom were checked WBC, CRP, and PCT. Chi-square analysis was used to compare results. Results Of the cases, 459 cases were bacterial pneumonia, and 280 cases were viral pneumonia. The positive percentage of WBC, CRP, and PCT were 47.9 %, 57.1%, and 85.2 %, respectively in 'bacterial pneumonia, and 21.1%, 7.1%, and 16.8 %, respectively in viral pneumonia. Conclusion WBC, CRP, and PCT could be useful in differentiating bacterial or viral pneumonia.
