儿童反复呼吸道感染与肺炎支原体感染相关性分析

Clinical analysis of the relationship between recurrent respiratory tract infection with Mycoplasma pneumonia infection

目的了解儿童反复呼吸道感染的发生与肺炎支原体（Mycoplasma pneumonnia，MP）感染之间的关系。方法采用颗粒凝集法对本院收治的118例反复呼吸道感染患儿进行血清MP特异性抗体（MP-IgM）测定，并进行临床分析。结果反复呼吸道感染患儿MP-IgM的总阳性率为38．98％（46／118），肺炎支原体感染率-3a和-6a组较高，分别为45．45％和46．67％。在46例肺炎支原体感染患儿中伴喘息者13例，占28．26％。结论儿童反复呼吸道感染与肺炎支原体感染关系密切，且是引起儿童喘息的重要诱因之一。

Objective To elucidate the relationship between recurrent respiratory tract infection and Mycoplasma pneumonia （MP） infection. Methods Serum MP-IgM was measured by partied agglutination in 118 children with recurrent respiratory tract infection, and the clinical analyses were performed. Results The positive rate of MP-IgM was 38.98% （46/118）. The infection rate of MP in group -3 years and group -6 years was 45.45% and 46.77%, which was higher than that in other groups. The proportion of children with gasp accounted for 28.26% （13/46）. Conclusions There is a close relationship between children＇s recurrent respiratory tract infection and Mycoplasma pneumonia infection, which may be an important precipitating factor of children＇s gasp.
