Methods The kit for IgM capture assay, was produced with a recombinant HEV structural protein protecting primates against experimental infection by different HEV genotypes, while the other kit for indirect ELISA was produced with recombinant structural proteins from different HEV geootypes. The serum specimens were taken from 241 cases with a confirmed or presumptive diagnosis of hepatitis A and 74 cases with a confirmed or presumptive diagnosis of hepatitis E. Results The sensitivity and specificity of the IgM capture assay kit were 97% and 100%, respectively, and the corresponding values for the other kit were 70% and 78%, respectively. Conclusion The IgM capture assay kit has higher sensitivity and specificity in diagnosing acute enteric viral hepatitis E.展开更多
目的:调查南京地区中孕孕妇戊型肝炎病毒(hepatitis E virus,HEV)的感染状况。方法:收集临床妊娠监测的中孕孕妇的血清,用酶联免疫吸附试验(ELISA)试剂检测戊型肝炎病毒的抗原、IgG抗体和IgM抗体。结果:在155例中孕孕妇血样中,HEV抗原...目的:调查南京地区中孕孕妇戊型肝炎病毒(hepatitis E virus,HEV)的感染状况。方法:收集临床妊娠监测的中孕孕妇的血清,用酶联免疫吸附试验(ELISA)试剂检测戊型肝炎病毒的抗原、IgG抗体和IgM抗体。结果:在155例中孕孕妇血样中,HEV抗原均呈阴性,1例HEV-IgM抗体阳性,3例HEV-IgG抗体阳性同时其HEV-IgM抗体滴度处于可疑区间,36例为单纯HEV-IgG抗体阳性,115例抗体均阴性。HEV-IgG抗体总的阳性率为25.16%(39/155),与对照组22.22%(20/90)相比,不存在统计学上的差异(P>0.05)。各年龄组之间,随着年龄增长,HEV-IgG抗体阳性率有升高的趋势,无统计学差异(P>0.05)。结论:孕妇戊型肝炎病毒感染现状不容忽视,为保证孕妇和新生儿的安全,建议在妊娠常规监测中增加戊型肝炎血清标志物的检测。展开更多
