摘要
目的探究EV71型IgG、IgM和IgA抗体在手足口病诊断中的应用价值。方法以2019年3月至2020年3月在我院收治的EV71感染的手足口病患儿116例,通过实时荧光定量聚合酶链式反应法对患儿感染的病毒类型进行检测,使用免疫层析法检测患儿血清中的EV71型IgG、IgM和IgA抗体。结果EV71型IgG、IgM和IgA抗体的阳性检出率分别为62.07%(72/116)、68.10%(79/116)和60.34%(70/116),与EV71核酸检测的阳性检出率72.41%(84/116)比较,差异无统计学意义(P>0.05)。轻症患儿的EV71型IgM和IgG抗体阳性检出率低于重症患儿,差异有统计学意义(P<0.01)。结论EV71型IgG、IgM和IgA抗体检测对手足口病显示出较好的诊断能力,重症EV71型IgM和IgG抗体阳性率高于普通患儿,提示对疾病的早期诊断和对症治疗有临床应用价值。
Objective To explore the application value of EV71 IgG,IgM and IgA antibodies in the diagnosis of hand-foot-mouth disease.Methods Totally 116 cases of children with hand-foot-mouth disease(HFMD)infected with EV71 who were treated in our hospital from March 2019 to March 2020 were selected,and the type of virus was detected by real-time fluorescent quantitative PCR,and the EV71 IgG,IgM and IgA antibodies were detected by immunochromatography.Results The positive rates of EV71 IgG,IgM and IgA antibodies were 62.07%(72/116),68.10%(79/116)and 60.34%(70/116),respectively,and the positive rate of EV71 nucleic acid test was 72.41%(84/116),the difference being not statistically significant(P>0.05).The positive rate of EV71 IgM and IgG antibody in mild children was lower than that in severe children,and the difference was statistically significant(P<0.01).Conclusion The diagnostic ability of the detection of EV71 IgG,IgM and IgA antibodies in hand-foot-mouth disease is good;the positive rate of IgM and IgG antibody of severe EV71 is higher than that of common children,which suggests that it has clinical application value for early diagnosis and symptomatic treatment of the disease.
