Mother-to-child transmission of hepatitis B virus (HBV) is the main cause of chronic hepatitis B (CHB) in China, and prevention of mother-to-child transmission of HBV plays a critical role in controlling CHB. On the basis of Clinical Guidelines on Prevention of Mother-to-Child Transmission of Hepatitis B Virus (2013) (hereinafter referred to as " 2013 HBV Prevention Guidelines" ), and according to the latest evidence-based medical evidences and literatures, Clinical Guidelines on Prevention of Mother-to-Child Transmission of Hepatitis B Virus (2020) (hereinafter referred to as " 2020 HBV Prevention Guidelines" ) were promulgated, so as to continuously optimize prevention and management strategies of mother-to-child transmission of HBV in China. The recommendations for " 2020 HBV Prevention Guidelines" mainly include the following nine aspects. ①Update points of clinical diagnostic criteria of HBV infection; ②Update points of HBV mother-to-child transmission; ③Update points of timing of pregnancy in women with CHB; ④Update points of management of pregnant women with CHB during pregnancy; ⑤Update points of neonatal immune prevention of HBV mother-to-child transmission of pregnant women with CHB; ⑥Prevention of HBV transmission in offspring whose pregnant mother is hepatitis B surface antigens (HBsAg) negative and other family members are HBsAg positive; ⑦New points to encourage mothers with CHB to breastfeed their newborns; ⑧Update points for follow-up of infants of pregnant women with CHB; ⑨Update points of other recommendations for prevention of HBV mother-to-child transmission. The authors intend to update the main points of the above nine aspects in" 2020 HBV Prevention Guidelines" , and interpret the guidelines in the light of the latest related clinical research progresses, in order to help obstetricians and pediatricians update this knowledge and provide reference for better clinical prevention of HBV mother-to-child transmission.

表1 与《HBV预防指南(2013)》比较,《HBV预防指南(2020)》在母婴HBV感染的临床诊断标准方面的新增要点
表2 与《HBV预防指南(2013)》比较,《HBV预防指南(2020)》在HBV母婴传播方面的新增要点
表3 《HBV预防指南(2020)》在不同肝功能状态CHB育龄妇女妊娠建议方面的更新要点
ALT水平(U/L) 肝纤维化 肝硬化 妊娠建议更新要点
正常(≤40) 定期复查肝功能,若正常,则可正常妊娠
增高(>40) 暂时避孕。采取休息等保守治疗措施(不采取抗HBV药物治疗),ALT水平恢复正常,并且稳定超过3个月后,则可正常妊娠。经上述保守治疗3个月后,ALT水平仍然异常者,或正常后反复出现异常者,则需进行抗HBV药物治疗,首选药物为富马酸替诺福韦二吡呋酯
正常(≤40) 可正常妊娠,但是孕期需要进行抗HBV药物治疗,产后亦需继续进行抗HBV药物治疗
增高(>40) 暂时避孕。首先采取口服抗HBV药物治疗,首选药物为富马酸替诺福韦二吡呋酯。若肝功能正常3个月后,则可正常妊娠。孕期、产后均需继续口服抗HBV药物治疗
正常(≤40) - 早期 一般不建议妊娠。对于有强烈生育要求者,若其全身状况综合评估较好(白蛋白水平>35 g/L、血小板计数>100×109/L等),则请肝病科医师会诊后,再决定是否可以妊娠。对于可以妊娠者,应对其于孕期、产后继续进行抗HBV药物治疗,首选药物为富马酸替诺福韦二吡呋酯
增高(>40) - 早期 必须严格采取避孕措施,同时进行抗HBV药物治疗,首选药物为富马酸替诺福韦二吡呋酯等综合治疗。对于具有强烈生育要求者,其肝功能恢复正常,并且稳定超过3个月后,若全身状况综合评估较好,则可考虑妊娠。但是,其孕期和产后,均应继续口服抗HBV药物治疗
- - 晚期 禁忌妊娠。若其处于肝硬化失代偿期,如脾功能亢进、食管和(或)胃底静脉曲张,或有肝性脑病、肝硬化腹水、消化道出血等病史者,禁忌妊娠。对肝癌妇女亦禁忌妊娠
