ABSTRACT
Objective Observe the changes of cytokine and immunoglobulin in children with Hand-foot-and-mouth disease (HFMD) infected by Enterovirus 71 (EV71),to explore the significance of inflammation and immunological mechanisms.Methods A total of 65 cases of children with HFMD by EV71 were taken as the observation group,and 65 cases of healthy children were as the control group in June 2015-August 2016.The serum levels of IL-6,IL-8,TNF-α were detected by enzyme-linked immunosorbent assay (ELISA),and the levels of IgA,IgG,IgM were detected by immune scattering turbidimetric.Results Compared with control group,the levels of IL-6,IL-8 and TNF-α in observation group were significantly increased (t=7.94,6.87,9.56,P ＜ 0.01),the levels of IgA,IgG and IgM also increased,differences were statistically significant (t =6.71,7.96,8.39,P ＜ 0.01).Conclusion The inflammatory cytokines and immune imbalance in the development of HFMD play an important role,observe the dynamic changes of IL-6,IL-8,TNF-α,IgA,IgG and IgM levels has certain clinical application value in preventing and judging the state of HFMD.
