92例反复呼吸道感染儿童肺炎支原体感染临床调查

目的探讨反复呼吸道感染儿童肺炎支原体感染发病率。方法对92例反复呼吸道感染的儿童进行肺炎支原体监测并与92例普通呼吸道感染患儿对照。两组采用颗粒凝聚法测定MP—IgM抗体。结果反复呼吸道感染者肺炎支原体MP—IgM阳性43例（46．74％），普通呼吸道感染者肺炎支原体MP—IgM阳性12例（13．04％），差异有极显著性（P〈0．01）。结论反复呼吸道感染与肺炎支原体感染关系密切，临床中应予以重视。

Clinical study on 92 cases of recurrent respiratory infection to children with mycoplasma pneumonia infection

Objective To study the relationship between recurrent respiratory infection （RRI） and mycoplasma pneumonia infection in children. Methods 92 children with RRI were selected as the experiment group and other 92 children with common respiratory infection as the control group. The MP- IgM antibody level was determined by particle agglutination method in both groups. Results The positive rate for MP-IgM was 46.74% in RRI group （43 cases） and 13.04% in the control group （12 cases）, with significant differences（P 〈 0.01） Conclusions RRI and mycoplasma pneumonia infection are closely correlated and should be paid more attention to.
