摘要

肺炎支原体是引起儿童社区获得性肺炎的重要病原体之一,肺炎支原体感染的致病机制复杂。阿奇霉素是治疗获得性下呼吸道感染和泌尿生殖道感染的有效药物,不良反应轻微。本研究旨在比较肺炎支原体肺炎患儿阿奇霉素干预前(PP1)与干预后(PP2)肠道菌群的变化,结合体液生化分析,确定影响病情进展的肠道菌群。招募了15名诊断为肺炎支原体肺炎的儿童。收集粪便标本及临床生化指标。16S rRNA基因扩增子测序和生物信息学分析由北京基因组研究所完成。操作分类单位丰度分析显示两组间存在显著差异。物种丰富度分析显示在纲、科、属、目、种和门上存在差异。发现PP1组中嗜血杆菌、巴氏杆菌和巴氏杆菌的丰度显著较高。Pearson相关分析显示,微生物与临床特征有很强的相关性。16S rRNA基因测序数据显示,阿奇霉素治疗后肺炎支原体肺炎患儿肠道菌群组成发生改变。微生物表达的改变与临床特征相关,这可能有助于诊断和治疗疾病。

16S rRNA gene sequencing reveals an altered composition of gut microbiota in children with Mycoplasma pneumoniae pneumonia treated with azithromycin.

Mycoplasma pneumoniae is one of the most important pathogens causing community acquired pneumonia in children, and the pathogenic mechanism of M. pneumoniae infection is complex. Azithromycin is an effective agent for treating the acquired lower respiratory tract infection and urogenital tract infection with slight adverse reactions. This study aimed to compare the intestinal microflora before (PP1) and after azithromycin intervention (PP2) in children with pneumonia caused by M. pneumoniae, combined with body fluid biochemical analysis to determine the intestinal flora affecting the progress of the disease. Fifteen children diagnosed with M. pneumoniae pneumonia were recruited. The fecal samples and clinical biochemical data were collected. 16S rRNA gene amplicon sequencing and bioinformatics analysis were conducted by the Beijing Genomics Institute. The operational taxonomic unit abundance analysis showed significant differences between the two groups. The species richness analysis showed differences in class, family, genus, order, species, and phylum. The abundance of Haemophilus, Pasteurellales, and Pasteurellaceae was found to be significantly higher in the PP1 group. The Pearson correlation analysis showed that the microbes strongly correlated with the clinical features. 16S rRNA gene sequencing data revealed altered composition of gut microbiota in children with M. pneumoniae pneumonia treated with azithromycin. The altered expression of microbes correlated with clinical features, which might help diagnose and treat the disease.
