Changes of serum cytokine levels in patients with hand-foot-and-mouth disease and therapeutic effects of intravenous immunoglobulin / 国际儿科学杂志

ABSTRACT

Objective To investigate the changes of cytokines in hand-foot-and-mouth disease( HFMD) patients.Methods Retrospective analysis was performed on the clinical data of 262 cases of HFMD.All 262 children with HFMD were divided into two groups:severe cases and non-severe cases.Five cytokines( IL-2,IL-6,IL-10,TNF-αand IFN-γ) simultaneously were detected by luminex multiplexed assays.Results There were 153 severe cases and 109 non-severe cases,The results showed that the levels of IL-2,IL-6,IL-10,TNF-αin severe cases were higher than non-severe cases,and the differences were significant (18.02 ng/L vs 22.71ng/L, 28.42 ng/L vs 53.76 ng/L,17.92 ng/L vs 42.37 ng/L,102.29 ng/L vs 207.99 ng/L,P0.05).In 40 critical cases,plasma levels of IL-2,IL-6,IL-10,TNF-α,and IFN-γwere significantly decreased after administration of intravenous immunoglobulin( P<0.05 ) .Conclusion Some cytokines increase in children with severe HFMD, indicating that inflammatory and anti-inflammatory reaction may play importent roles in the pathogenesis of se-vere HFMD.The findings suggest that intravenous immunoglobulin might play a therapeutic role in severe HFMD.
