Methods: A total of 130 children with upper respiratory tract infection who were treated in the hospital between February 2016 and February 2017 were divided into control group and secretory IgA group by random number table method, each group with 65 cases. Control group received routine anti-infectious drug treatment, and secretory IgA group received the secretory IgA combined with conventional anti-infectious drug treatment, which lasted for 1 week. The differences in serum levels of routine inflammatory factors, fat inflammatory factors and immunoglobulin were compared between the two groups before and after treatment. Results: There was no statistically significant difference in serum levels of normal inflammatory factors, fat inflammatory factors and immunoglobulin between the two groups before treatment. After 1 week of treatment, serum conventional inflammatory factors CRP, IL-1 and IL-8 levels of secretory IgA group were lower than those of control group;serum fat inflammatory factors SAA and Chemerin levels were lower than those of control group whereas Leptin level was higher than that of control group;serum immunoglobulin IgA, IgG and IgM contents were higher than those of control group. Conclusion: The secretory IgA combined with conventional anti-infectious drugs can effectively inhibit the systemic inflammatory response and enhance the humoral immune response in children with upper respiratory tract infection.展开更多
