摘要
乙型肝炎病毒(hepatitis B virus,HBV)感染是全球重大公共卫生健康问题之一,是慢性肝炎的最常见原因,发病率和病死率较高。我国属于HBV感染率高的国家,妊娠期母婴传播(mother to child transmission,MTCT)仍然是HBV的主要传播方式,乙肝疫苗联合乙肝免疫球蛋白(hepatitis B immunoglobulin,HBIG)主动-被动免疫是减少MTCT的有效途径,但仍有发生HBV MTCT风险,尤其是HBV DNA高病毒载量的孕妇。因此,妊娠期间应监测HBV DNA病毒载量以评估MTCT的风险和制定抗病毒治疗方案。HBV DNA≥2×10^(5)IU/mL时应提倡在妊娠28周开始富马酸替诺福韦二吡呋酯(tenofovir disoproxil fumarate,TDF)等抗病毒治疗,以降低MTCT的风险。
Hepatitis B virus(HBV)infection is one of the major public health problems in the world,which is the most common cause of chronic hepatitis,with a high morbidity and mortality.China is a country with a high HBV infection rate.Mother to child transmission(MTCT)during pregnancy is still the main mode of HBV transmission.The active and passive immunization with hepatitis B vaccine and hepatitis B immunoglobulin(HBIG)is an effective way to reduce MTCT,but there is still a risk of HBV MTCT,especially for pregnant women with high viral load of HBV DNA.Therefore,HBV DNA viral load should be monitored during pregnancy to assess the risk of MTCT and formulate antiviral treatment plan.When HBV DNA≥2×10^(5) IU/mL,it is recommended to start antiviral therapy such as tenofovir disoproxil fumarate(TDF)at 28 weeks of pregnancy to reduce the risk of MTCT.
