SUMMARYAt an antenatal clinic at a Melbourne obstetric hospital, 308 women were questioned about a known past history of infection with varicella zoster virus (VZV), human parvovirus B19 and Toxoplasma gondii. Immunoglobulin G (IgG) concentrations were determined for the 3 infectious agents and a recalled history of infection was compared with the presence of specific antibody. Exactly 66% of women recalled being infected with chickenpox (VZV) and 94% showed serological evidence of past exposure. Although 64% of women had parvovirus specific IgG, only one gave a definite history of past parvovirus infection. None of the 23% of women with evidence of previous exposure to Toxoplasma gondii recalled a past infection. The proportion of antenatal women at risk in this study was used to estimate the potential burden of disease from congenital infections in Australia and to examine implications for management of pregnancies complicated by these 3 infections.
摘要在墨尔本一家产科医院的产前门诊中,308 名产妇被问及过去是否感染过水痘带状疱疹病毒 (VZV)、人类细小病毒 B19 和弓形虫。测定了这三种传染源的免疫球蛋白 G (IgG) 浓度,并将回忆起的感染史与特异性抗体的存在进行了比较。66%的妇女回忆起曾感染过水痘(VZV),94%的妇女有血清学证据表明曾接触过水痘。虽然 64% 的妇女有 parvovirus 特异性 IgG,但只有一名妇女明确表示过去曾感染过 parvovirus。在有证据表明曾接触过弓形虫的 23% 孕妇中,没有一人回忆起曾感染过弓形虫。这项研究中的产前高危妇女比例被用来估算澳大利亚先天性感染可能造成的疾病负担,并研究这三种感染对并发妊娠管理的影响。
