冬季成人急性呼吸道疾病住院患者肺炎支原体抗体检测及分析

Test and analysis the antibody of Mycoplasma pneumoniae in winter adult respiratory department inpatients

目的了解冬季住院既往体健和有慢性肺部基础疾病患者急性呼吸道疾病的肺炎支原体感染情况。方法选择2008年12月中旬至2009年3月北京军区总医院呼吸内科收治的急性呼吸道疾病患者73例,应用被动明胶颗粒凝集试验检测患者血清中肺炎支原体抗体滴度,以抗体滴度≥1:160判为阳性。结果既往体健组的肺炎支原体感染率为48.3%,慢性肺部基础疾病组肺炎支原体感染率为22.7%,两组之间感染率差异有统计学意义(P<0.05)。既往体健组的年龄明显小于有基础性肺部疾病组(P<0.05),而且MP的感染率与性别无关(P>0.05)。结论既往体健的急性呼吸道感染青壮年患者肺炎支原体感染率明显高于有慢性肺部基础疾病的患者。

Objective To explore the prevalence of Myeoplasma pneumoniae（MP） infection in the people who had no disease and who had chronic lung disease. Methods Use passive particle agglutination to test the antibody in the serum, teat the antibody titer≥ 1 ： 160 〈0.05 ） ,the MP inlet- as positive. Results The group had no chronic disease are younger than the gruu!d who had chronic lung disease（ P tion in the group had no chronic disease is 48.3%, in the group had chronic lung disease is 22. 7%, There was statistically significant difference in infection rate between the two groups（ P 〈 0. 05 ）. The MP infection rate has no relation with sex（ P 〉 0. 05. Conclusion In winter,inpatient of respiratory department, the MP infection rate in the people who no chronic disease is higher than the people who had chronic lung disease.
