| 摘 要： | 持续性乙型肝炎病毒(hepatitis B virus，HBV)感染分为两类：乙型肝炎表面抗原(hepatitis B surface antigen，HBsAg)阳性(显性HBV感染)和阴性(隐匿性HBV感染，occult hepatitis B infection，OBI)。对显性感染的认识相对清楚，但对OBI的认识仍然有限。本文重点介绍OBI的危害及其流行情况，并分别阐述了母婴不同乙肝传播类型与乙肝疫苗免疫效果的关系。HBV以母婴传播为主，两类HBV感染在母婴传播上表现为四种类型：(Ⅰ)母亲HBV显性-子代HBV显性; (Ⅱ)母亲HBV显性-子代OBI; (Ⅲ)母亲OBI-子代OBI; (Ⅳ)母亲OBI-子代HBV显性。HBV疫苗免疫后时代可能以Ⅱ型传播为主。应加强对OBI的研究，重新评估现有HBV免疫策略对HBV母婴传播的影响。

| Abstract: | Persistent hepatitis B virus (HBV) infection can be classified into two categories:HBsAg-positive (overt HBV infection, overt-HBI) and HBsAg negative (occult hepatitis B infection, OBI).The understanding of overt-HBI is relatively clear; however, the knowledge of OBI remains limited.Mother-to-infant transmission is the main route of HBV transmission.Considering the existence of OBI, HBV transmission from mother to infant are composed of four types, (Ⅰ) overt-HBI to overt-HBI, (Ⅱ) overt-HBI to OBI, (Ⅲ) OBI to OBI, and (Ⅳ) OBI to overt-HBI.In the real world, current neonatal immunization strategy is based on mothers′ status of overt-HBI and has successfully blocked the type-Ⅰ transmission.However, the effects of HBV vaccine on the other three types are not clear.In this review, we focus on the threat and epidemic of OBI and describe the relationship between the four transmission types above and efficacy of HBV vaccination.We found that, in post-immunization era, the type Ⅱ may dominate mother-to-infant transmission of HBV.More studies on OBI should be conducted to reassess the effect of existing hepatitis B immunization strategies on HBV mother-to-child transmission. |
