摘要: 目的 分析肺炎支原体(MP)肺炎患儿黏液栓形成与MP菌量、混合细菌或病毒感染的相关性。方法 选取2014年6月—2015年12月河北省儿童医院收治的MP感染所致肺实变患儿87例,根据支气管镜下表现,将患儿分为黏液栓组(34例)和非黏液栓组(53例)。采用实时荧光定量聚合酶链式反应对患儿肺泡灌洗液(BALF)进行MP-DNA定量;取痰液及BALF用于细菌培养;采用GeXP多重基因表达分析系统联合多重反转录-聚合酶链反应检测痰液病毒。结果 黏液栓组高菌量比例、混合病毒感染率分别为64.7%(22/34)、52.9%(18/34),高于非黏液栓组的24.5%(13/53)、20.8%(11/53)(P<0.05)。两组混合细菌感染率比较,差异无统计学意义(P>0.05)。多因素Logistic回归分析显示,高菌量〔OR=10.682,95%CI(1.447,78.877)〕是MP肺炎患儿黏液栓形成的危险因素(P<0.05)。结论 MP肺炎患儿黏液栓的形成与MP菌量、混合病毒感染有关,而未见与患儿性别、年龄有关。

Abstract: Objective To explore the correlation of mucus plug formation in children with mycoplasma pneumoniae(MP) pneumonia and MP load,mixed bacteria or virus infection.Methods A total of 87 children with lung consolidation infected by MP admitted to Children' s Hospital of Hebei Province between June 2014 and December 2015 were divided into mucus plugs group(34 cases) and non-mucus plugs group(53 cases) according to the image of flexible bronchoscopy.MP-DNA was quantitatively detected by fluorescent real-time PCR in bronchoalveolar lavage fluid(BALF),bacterial culture was conducted from sputum and BALF,and the GeXP based mRT-PCR assay was performed to test sputum viruses.Results The proportion of high MP load and mixed virus infection rate in mucus plug group were 64.7%(22/34)and 52.9%(18/34),higher than those of non-mucus plugs group〔24.5%(13/53),20.8%(11/53)〕(P<0.05).There was no statistic difference in the two groups in terms of the mixed bacteria infection rate(P>0.05).The Logistic regression analysis indicated that high MP load〔OR=10.682,95%CI(1.447,78.877)〕 was the risk factor for mucus plugs in children with MP pneumonia(P<0.05).Conclusion The formation of airway mucus in children with MP pneumonia is related to high MP load and mixed virus infections,but not related to sex and age.
