成人呼吸道感染患者肺炎衣原体感染分析

Infection analysis of chlamydia pneumonia in adult patients with respiratory tract infection

目的分析呼吸道感染住院成人患者肺炎衣原体(CP)Ig M抗体的性别、年龄和时间分布特点。方法收集1 647例呼吸道感染成人患者血清,采用胶体金法检测血清CPIg M抗体。结果 1 647例患者CPIg M抗体阳性率为12%;男女患者CPIg M抗体阳性率差异无统计学意义;随人群年龄的增加,CPIg M抗体阳性率逐渐下降;2013年1~3月,CPIg M抗体阳性率较低,从4月开始阳性率明显上升,到10月又有下降趋势。结论对于在夏、秋季出现的呼吸道感染年轻患者,应考虑CP感染的可能性。

Objective To investigate the distribution of the prevalence of Chlamydia pneumonia（ CP） Ig M antibodies by gender,age and month in adult patients with respiratory tract infections. Methods Colloidal gold immuno-assay was used to detect CPIg M antibodies in 1647 adult patients with respiratory tract infections. Results The seroprevalence of CPIg M antibodies in 1647 patients was 12%. No significant difference was found between males and females. The seroprevalence of CPIg M antibody decreased gradually with the age group increasing. In 2013,the seroprevalence of CPIg M antibody was the lowest between January and March,it’s significantly increased from April,and there was a downward trend from October. Conclusion CPinfection should be taken into consideration for young patients with respiratory tract infection in summer and autumn.
