为评估在妊娠期和分娩期,母婴传播丙型肝炎病毒的危险性,美国的Weintrub P S等人检查了43名婴儿的血清,用酶连免疫吸附测定法(ELISA)和重组免疫印迹法(RIBA)检测其丙型肝炎病毒抗体(anti-HCV)。这些婴儿的母亲都是静脉注射毒品成瘾者。生后前4个月的43名婴儿中,有17人(40％)检出受母亲被动传播的anti-HCV。对其中的10名婴儿(血清阳性者)随访至15个月左右。9
To assess the risk of mother-to-child transmission of hepatitis C virus during pregnancy and childbirth, Weintrub PS et al. In the United States examined sera from 43 infants and examined serum levels by enzyme-linked immunosorbent assay (ELISA) and recombinant immunoblotting RIBA) to detect its anti-HCV antibody. The mothers of these infants are intravenous drug addicts. Of the 43 infants in the first 4 months of life, 17 (40%) detected anti-HCV that was passively transmitted by their mothers. Ten of these infants (seropositive) were followed up for about 15 months. 9
