Objective: To explore the value of IgM and IgG contents for the diagnosis and judgment of mycoplasma pneumonia in children. Methods: 560 children with mycoplasma pneumonia who received inpatient treatment in our hospital between October 2016 and October 2017 were selected as mycoplasma pneumonia group, and 200 healthy children who received vaccination in our hospital during the same period were selected as normal control group. The differences in peripheral blood IgM and IgG contents as well as serum inflammatory factor and pulmonary surfactant protein contents were compared between the two groups, and Pearson test was used to evaluate the inner link of peripheral blood IgM and IgG contents with inflammatory factors and pulmonary surfactant proteins in children with mycoplasma pneumonia. Results: Peripheral blood IgM and IgG contents of mycoplasma pneumonia group were higher than those of normal control group; serum inflammatory factors MCP-4, IL-5, IL-13, IL-17, IL-18 and IL-23 contents were higher than those of normal control group; serum pulmonary surfactant proteins SP-A, SP-B, SP-C and SP-D contents were higher than those of normal control group. Correlation analysis showed that peripheral blood IgM and IgG contents in children with mycoplasma pneumonia were positively correlated with the contents of inflammatory factors and pulmonary surfactant proteins. Conclusion: Peripheral blood IgM and IgG contents are abnormally high in children with mycoplasma pneumonia, and they are closely related to the inflammatory response and lung injury degree.
