前降钙素在儿科社区感染性肺炎的检测及临床意义

Detection and clinical significance of PCT in paediatrics community acquired pneumonia

目的评价血清前降钙素在儿科鉴别细菌感染性肺炎中的作用。方法应用入院时进行血清前降钙素水平测定,并比较血清CRP、白细胞计数,旨在评价PCT在小儿肺炎病原学辅助诊断中的价值。结果34例细菌感染性肺炎血清前降钙素水平轻中度升高,28例病毒感染性肺炎及25例支原体或沙眼衣原体肺炎血清前降钙素基本正常,细菌性肺炎及病毒性肺炎两组患者血清CRP升高有一重叠带,而PCT检测值在两组中无交叉对照组血清前降钙素正常。结论血清前降钙素是早期鉴别细菌感染性肺炎重要指标。

Objective To evaluate the function of PCT in identifying bacterial pneumonia. Methods To evaluate the value of PCT in etiology auxiliary diagnosis of pediatric pneumonia, we detected the serum level of PCT and compared CRP and WBC count on admission. Results The serum level of PCT rised mild-to-moderate in 34 cases bacterial pneumonia and the level was normal in 28 cases viral pneumonia and 25 cases mycoplasma or chlamydia pneumonia. The rising of CRP had an overlapping zone between bacterial pneumonia and viral pneumonia. The detection numerus of PCT in achiasmate control group was normal. Conclusion PCT is important index in earlier period identification of bacterial pneumonia.
