目的 探讨慢性乙型肝炎病毒（HBV）感染对妊娠期糖尿病（GDM）孕妇的妊娠并发症、孕晚期生殖道B族链球菌（GBS）感染情况以及妊娠结局的影响。方法 选取2020年1月1日—12月31日在广州市妇女儿童医疗中心定期产检、足月、单胎妊娠的GDM孕妇共583例,其中合并HBV感染者（GDM+HBV组）48例,无合并者（GDM组）535例。比较2组的妊娠期并发症、妊娠晚期（妊娠35~37周）生殖道GBS感染情况、妊娠结局以及阴道分娩者的母儿结局。结果 与GDM组患者相比,GDM+HBV组患者出现妊娠期肝内胆汁淤积症、孕晚期生殖道GBS感染者比例较高,孕期出现胎盘早剥者比例较高,阴道分娩过程中出现产时发热、羊水粪染和新生儿入住NICU者比例均较高（均P<0.05）。结论 与无合并慢性HBV感染的GDM患者相比,合并慢性HBV感染的GDM患者在围产期的母儿风险升高。

Objective To investigate the effects of chronic hepatitis B virus（HBV）infection on pregnancy complications,group B streptococcus（GBS）infection in third trimester and pregnancy outcome in pregnant women with gestational diabetes mellitus（GDM）．Methods A retrospective study of 583 pregnant women with GDM,singleton gestation and cephalic presentation delivered at term in Guangzhou Women and Children’s Medical Center was carried out．Including 48 GDM women complicated with chronic HBV infection（GDM+HBV group）and 535 GDM women without HBV infection（GDM group）．Pregnancy complications,GBS infection in third trimester（gestation 35-37 weeks）,pregnancy outcomes,maternal and neonatal outcomes of vaginal delivery were compared between the two groups．Results GDM+HBV group had a higher proportion of intrahepatic cholestasis of pregnancy（ICP）and GBS infection in third trimester than GDM group,and a higher proportion of placental abruption during pregnancy．GDM+HBV group showed a significantly increased proportion in intrapartum fever,meconium-stained amniotic fluid and neonatal intensive care unit admission during vaginal delivery than GDM group（all P<0.05）．Conclusions GDM women with chronic HBV infection are associated with increased maternal and fetal risk during pregnancy and delivery．

目的 分析妊娠期慢性乙型肝炎病毒携带者病毒载量与孕妇肝功能、妊娠并发症的相关性。方法 将本院2015年1月—12月间在本院住院并于本院分娩的携带慢性乙型肝炎病毒(HBV)的86例孕妇作为本次研究对象,于住院期间分娩前测定孕妇HBV脱氧核糖核酸(HBV-DNA)定量,依据HBV-DNA定量测定结果将全部患者分为阴性组与阳性组,分别对比2组患者的临床资料、肝功能、妊娠并发症发生率及母婴结局;分析HBV-DNA载量与孕妇妊娠期肝功能及妊娠并发症的相关性。结果 2组孕妇的年龄、BMI、孕次与产次均无差异,P>0.05;阴性组患者妊娠期肝功能指标优于阳性组,P<0.01。阴性组中羊水量异常(偏多或偏少)发生率高于阳性组,P<0.05;其他妊娠期并发症发生率2组均未见差异,P>0.05。2组母婴结局均未见统计学差异,P>0.05。HBV载量与ALT肝功能指标均呈正相关,0<r<1,说明HBV-DNA越高则ALT越高,孕妇的肝功能越差。HBV载量与并发症发生间基本不相关,|r|<0.3,P>0.05。结论 慢性乙型肝炎病毒携带者妊娠期时随着病毒载量的升高,孕妇的肝功能有所下降仍可维持在正常标准,但与妊娠并发症的发生无相关性;提示对HBV-DNA阳性的孕妇给予密切监护,通过临床常规对症治疗能够保证母婴安全。

Objective To analyze the correlation between viral load of chronic hepatitis B virus infection and liver function and pregnancy complications. Methods We selected 86 cases of pregnant women with chronic hepatitis B virus(HBV)in our hospital from January 2015 to December 2015 as the research objects, and then during the hospitalization to test the quality of the HBV deoxyribonucleic acid (HBV-DNA)for them before delivery. According to the HBV-DNA quantitative results, all patients were divided into low dosage group and high dosage group, and then the clinical data, liver function, the incidence rate of pregnancy complications and the outcomes of the two groups were compared; at last we analyzed the correlation among the HBV-DNA load, liver function of pregnant women during pregnancy and pregnancy complications. Results There was no difference between the two groups of pregnant women in the age, BMI, pregnancy and birth time, P>0.05; the low dose group was better than the high dose group in the liver function index during the pregnancy, P<0.01. The incidence of abnormal amniotic fluid volume (more or less) in the low dose group was higher than that in the high dose group, P<0.05; there was no significant difference between the two groups in the incidence of other complications, P>0.05. There was no statistical difference between the two groups in maternal and neonatal outcomes, P>0.05. The HBV load was positively correlated with the two liver function indexes ALT, 0<r<1, indicating that the higher the HBV-DNA, the higher theALT, the worse the liver function of the pregnant women. There was no correlation between HBV load and complications, |r|<0.3, P>0.05. Conclusion Chronic hepatitis B virus carriers during pregnancy with increasing viral load, liver function of pregnant women declined to maintain in normal level, but not associated with pregnancy complications; that of HBV-DNA positive pregnant women given close monitoring of disease through clinical routine treatment can ensure the safety of mother and child.
