目的通过对婴幼儿及学龄前儿童肺炎支原体患儿降钙素原、C-反应蛋白和白细胞计数检测结果进行分析,探讨其内在联系,为临床诊断提供参考。方法肺炎支原体阳性婴幼儿和学龄前儿童共76例,均进行降钙素原、C-反应蛋白和白细胞计数检验,比较上述指标的阳性率。结果降钙素原阳性率明显高于其他两种,差异有统计学意义(P<0.05)。结论降钙素原对于支原体肺炎检测具有较高的敏感度,C-反应蛋白和白细胞计数不能单独作为诊断依据。
Objective To analyze the results of procalcitonin, C-reactive protein and leukocyte count in children with infantile and preschool children with Mycoplasma pneumoniae, and to explore its internal relations and provide a reference for clinical diagnosis. Methods A total of 76 cases of Mycoplasma pneumoniae-positive infants and preschool children were tested for procalcitonin, C-reactive protein and white blood cell count, and the positive rates of these indexes were compared. Results The positive rate of procalcitonin was significantly higher than the other two, the difference was statistically significant (P <0.05). Conclusions Procalcitonin has a high sensitivity for mycoplasma pneumonia. C-reactive protein and white blood cell count can not be used as a basis for diagnosis alone.
