尽管以色列的社会经济条件和卫生状况已有了明显改善,但甲型肝炎发病率仍持续上升,尤其在青少年中甲型肝炎病毒抗体(抗-HAV)的分布呈下降趋势。而经胎盘传递的母体抗-HAV抗体,为新生儿预防甲型肝炎提供被动保护作用,因此1岁以下婴儿极少被HAV感染。本文作者对甲型肝炎流行区抗-HAV在母婴之间的传递及其免疫保护作用作了研究,并且在足月生和不足月生婴儿中进行了比较。作者将250名健康以色列产妇及其新
Despite the significant improvement in socio-economic conditions and health conditions in Israel, the incidence of hepatitis A continues to rise, especially in adolescents, with a decreasing trend in the distribution of anti-HAV antibodies. The mother’s anti-HAV antibody delivered through the placenta provides passive protection for hepatitis A in infants, so infants under 1 year of age are rarely infected with HAV. The authors studied the anti-HAV transmission in hepatitis A endemic areas and their immunoprotective effects between mothers and infants, and compared them with term infants and infants. The author will be 250 healthy Israeli women and their new
