ABSTRACT
Objective To investigate the expressions of Th17, CD4 +CD25 +Treg, HLA-DR mRNA in peripheral blood of children with EV71-induced hand, foot and mouth diseases ( HFMD ) and their clinical significance.Methods Stratified random sampling was used to select 60 children with HFMDs from Liaocheng People’s Hospital from February to October, 2014, including 20 mild, 20 severe and 20 critically ill cases.Twenty healthy children were also enrolled as the control group.All the children with HFMDs were given ribavirin (10 mg/kg) for the treatment.The percentages of Th17 and CD4 +CD25 +Treg cells in CD4 +T cells of peripheral blood were determined by flow cytometry, and the expression of HLA-DR mRNA in peripheral blood mononuclear cells was detected by reverse transcription polymerase chain reaction ( RT-PCR).Analysis of variance and SNK-q test were used to compare the expressions of Th17, CD4 +CD25 +Treg and HLA-DR mRNA among groups, and Pearson correlation analysis was performed to reveal the correlations between HLA-DR mRNA and Th17, CD4 +CD25 +Treg.Results Compared with the control group, the expression of Th17 was increased, while CD4 +CD25+Treg and HLA-DR mRNA expressions were decreased in children with HFMDs on d1 of treatment (F=310.4, 81.5 and 545.4, P0.05), but Th17 level in fatal was still higher and CD4 +CD25 +Treg level was still lower than those in control group (t=16.4 and 12.0, P<0.05).After 10 d of treatment, HLA-DR mRNA expressions in mild group and severe group were increased to the normal level.HLA-DR mRNA expression in surviving patients of critical ill group was still lower than that in mild group and severe group (P<0.05), but was higher than that in fatal patients (t=7.8, P<0.05).Pearson correlation analysis showed that, HLA-DR mRNA was negatively correlated with Th17 level (r=-0.770, P<0.01), and positively correlated with CD4 +CD25 +Treg level (r=0.883, P<0.01).Conclusion The expressions of Th17, CD4 +CD25 +Treg cells, and HLA-DR mRNA are correlated with the severity of HFMD, and may be used for evaluation of disease severity and prediction of disease outcomes.
