血清降钙素原在小儿病毒性肺炎及细菌性肺炎中的诊断价值

The diagnostic values of serum procalcitonin for viral pneumonia and for bacterial pneumonia in children

目的对比分析血清降钙素原(PCT)在小儿病毒性肺炎及细菌性肺炎中不同表现,明确PCT在小儿病毒性肺炎及细菌性肺炎中临床价值,为治疗小儿肺炎提供临床参考。方法随机选取2014年3月至2015年4月收治的小儿病毒性肺炎患者96例(观察组),另选取同期本院收治的细菌性肺炎患者96例(对照组),两组儿童均接受PCT相关检测,并行统计分析相关检测结果以及应用价值。同时记录患儿年龄、性别、身高、体重等一般情况,应用统计学软件对以上数据进行分析。结果观察组患儿PCT平均值为(0.29±0.14)ng/ml,阳性率为9.38%;对照组患儿PCT平均值为(3.18±0.74)ng/ml,阳性率为93.75%,组间对比差异有统计学意义(P<0.05)。结论 PCT在小儿病毒性肺炎中的阳性率高于细菌性肺炎,一定程度上可作为临床诊断小儿病毒性肺炎的一项临床指标。

Objective To compare the levels of procalcitonin （PCT） in children with viral pneumonia and in children with bacterial pneumonia, and evaluate the clinical value of PCT for the diagnosis of viral pneumonia and bacterial pneumonia in children and provide clinical reference for the treatment of pneumonia in children. Methods 96 cases of pediatric patients with viral pneumonia and 96 cases of pediatric patients with bacterial pneumonia were selected randomly from March 2014 to April 2015 in our hospital as observation group and control group, respectively, for the study. PCT level was measured and analyzed for the diagnosis value. Age, gender, height and weight were also recorded. Results The average level of PCT of the control group was （0.29 ±0.14） ng/ml, with the positive rate of 9.38%; the average level of PCT of the observation group was （3.18 ±0.74）ng/ml, with the positive rate of 93.75%,showing a significant difference between these two groups （P〈0.05）. Conclusion PCT level was higher in children with viral pneumonia than that with bacterial pneumonia; it could be used as a clinical indicator of diagnosis of viral pneumonia in children.
