目的探讨儿童急性呼吸道感染血清免疫球蛋白M(IgM)与病原体之间的关系。方法采用ELISA法对584例急性呼吸道感染患儿血清中的IgM抗体进行测定,然后分析与病原体之间的关系。结果 199例IgM测定阳性,阳性率34.08%。肺炎支原体检出率最高为40.20%,其次是呼吸道合胞病毒检出率32.66%。结论肺炎支原体和呼吸道合胞病毒是儿童急性呼吸道感染常见病原体,可为临床治疗提供重要信息。
Objective To investigate the relationship between serum immunoglobulin M (IgM) and pathogens in children with acute respiratory infection. Methods Serum IgM antibodies in 584 children with acute respiratory tract infection were measured by ELISA, and the relationship with pathogens was analyzed. Results 199 cases of IgM positive, the positive rate of 34.08%. Mycoplasma pneumoniae detection rate was the highest 40.20%, followed by respiratory syncytial virus detection rate of 32.66%. Conclusions Mycoplasma pneumoniae and respiratory syncytial virus are common pathogens of acute respiratory infection in children and may provide important information for clinical treatment.
