摘要:

目的 探讨肺炎支原体(Mycoplasma pneumoniae,MP)感染合并喘息性支气管肺炎患儿临床特征。方法 选取2021年9月至2023年2月郑州大学附属儿童医院收治的50例MP感染合并喘息性支气管肺炎患儿为观察组,选取同期来我院就诊的50例MP感染但未合并喘息性支气管肺炎患儿为对照组。比较两组T淋巴细胞亚群(CD3+、CD4+、CD8+)、免疫球蛋白[(免疫球蛋白G(IgG)、免疫球蛋白M(IgM)、免疫球蛋白E(IgE)]、肺功能[肺活量(VC)、第1秒用力呼气容积(FEV1)、用力肺活量(FVC)、峰值流速(PEF)、最大呼气中段流量(MMEF)]、血清炎症因子(TGF-β1、TNF-α)和补体C3水平。结果 ①观察组CD3+、CD4+、CD8+水平均高于对照组(P<0.05)。②观察组IgG、IgM、IgE水平均高于对照组(P<0.05)。③观察组VC、FEV1、FVC、PEF、MMEF水平均低于对照组(P<0.05)。④两组TGF-β1水平差异无统计学意义(P>0.05);观察组TNF-α、补体C3水平高于对照组(P<0.05)。结论 MP感染合并喘息性支气管肺炎患儿的免疫反应显著,肺功能降低,TNF-α和补体C3水平升高。

Abstract:

Objective To investigate the clinical characteristics of children with Mycoplasma pneumoniae (MP) infection complicated with asthmatic bronchopneumonia. Methods Fifty children with MP infection and asthmatic bronchopneumonia admitted to Children's Hospital Affiliated to Zhengzhou University from September 2021 to February 2023 were selected as the observation group, and 50 children with MP infection but not asthmatic bronchopneumonia during the same period were selected as the control group. The levels of T cell lymphocyte subsets (CD3+, CD4+, CD8+), immunoglobulins (IgG, IgM and IgE), and lung function (vital capacity [VC], forced expiratory volume in the first second [FEV1], forced vital capacity [FVC], peak expiratory flow [PEF], maximum mid-expiratory flow [MMEF]), serum inflammatory factors (transforming growth factor-beta1 [TGF-β1], tumor necrosis factor alpha [TNF-α]), and complement C3 levels were compared. Results The levels of CD3+, CD4+, CD8+ in the observation group were significantly higher than those of control group (p<0.05). IgG, IgM, and IgE levels in the observation group were significantly higher than the control group (P<0.05). The levels of VC, FEV1, FVC, PEF and MMEF in the observation group were significantly lower than those of control group (P<0.05). The levels of TNF-α and complement C3 in the observation group were significantly higher than those of control group (P<0.05). There was no significant difference in TGF-β1 level between the two groups (P>0.05). Conclusion Children with MP infection and asthmatic bronchopneumonia have a significant immune response, reduced pulmonary function, and increased levels of TNF-α and complement C3.
