摘要
目的探讨血清降钙素原(PCT)、C反应蛋白(CRP)、白细胞(WBC)在小儿肺炎患儿病情评估中的临床意义。方法随即选取121例肺炎患儿,其中细菌性肺炎59例(组A),病毒性肺炎62例(组B),测定两组患儿血清PCT、CRP、WBC值,比较三个指标鉴别细菌性肺炎和病毒性肺炎的敏感性和特异性。结果 PCT在诊断细菌性肺炎时敏感性为85.9%,特异性为92%,CRP诊断细菌性肺炎时敏感性为59.2%,特异性为88%,WBC诊断细菌性肺炎时敏感性为70.4%,特异性为62%。结论血清降钙素原水平有助于小儿肺炎的鉴别诊断,并较CRP和WBC具有较高的敏感性和特异性。
Objective To detect the clinical value of the levels of serum procalcitonin（PCT）,C-reactive protein（CRP） and white cell count（WBC） in children with pneumonia.Methods 121 children with pneumonia were divided randomLy into bacterial pneumonia group（group A,n=59） and virus pneumonia group（group B,n=62）.PCT,CRP and WBC levels were detected in all cases.Compare the sensitivity and specificity of three indicators in discriminating bacterial pneumonia and virus pneumonia.Results Sensitivity of PCT in diagnosing bacterial pneumonia was 85.9%,and specificity was 92%.Sensitivity of CRP in diagnosing bacterial pneumonia was 59.2%,and specificity was 88%.Sensitivity of WBC in diagnosing bacterial pneumonia was 70.4%,and specificity was 62%.Conclusions PCT is a valuable indicator in the diagnosis of bacterial pneumonia in children and has higher sensitivity and specificity than CRP and WBC.
