| 目的 探讨孕中期和孕晚期妊娠期肝内胆汁淤积症(ICP)对分娩结局的影响。方法 在马鞍山市优生优育队列(MABC)中,将孕周≤14周、符合入组标准的孕妇共3 474人纳入队列,在首次产检时收集孕妇的一般人口学信息,并收集孕中期和孕晚期血清总胆汁酸(TBA)的检测结果,符合临床诊断的作为病例,采用logistic回归分析孕中期和孕晚期ICP对分娩结局的影响。结果 最终分析的样本人数为2 978人,ICP发生率为6.5%(n=196),其中孕中期和孕晚期ICP发生率分别为1.4%(n=43)和5.1%(n=153)。控制了潜在的混杂因素后,孕中期和孕晚期ICP均增加胎儿早产、低出生体重(LBW)、胎儿窘迫和羊水粪染的风险,OR值(95% CI)分别为6.42(2.59~15.93)和3.73(2.07~6.72);6.52(2.19~19.45)和4.90(2.43~9.90);2.91(1.27~6.67)和1.88(1.11~3.19);2.34(1.19~4.61)和1.66(1.11~2.48),并且孕中期ICP组发生上述不良分娩结局的风险远远高于孕晚期ICP组。结论 孕中期和孕晚期ICP均显著增加胎儿不良分娩结局的风险,孕中期ICP尤其值得关注,早期发现和干预对降低不良分娩结局的发生意义重大。 |

| Objective To evaluate the relations between the second and third trimesters intrahepatic cholestasis of pregnancy(ICP) and the fetal outcomes, in order to provide medical advice for early detection and intervention on ICP.Methods A prospective cohort study was conducted in Ma'anshan, Anhui, China(Ma'anshan Birth Cohort, MABC).Pregnant women within 14 weeks of gestation were consecutively recruited when standards were met.Anthropometrics were collected in early pregnancy.Maternal serum total bile acid level(TBA) was collected in the second and third trimesters, and women were viewed as cases if the results were accorded with clinical diagnosis.Logistic regressions were conducted to examine the associations of the second and third trimester ICP, and fetal outcomes.Results A total of 2 978 pregnant women were included in this study.The rate of ICP was 6.5%(n=196), and the rates of the second and third trimesters were 1.4%(n=43) and 5.1%(n=153) respectively.After controlling for potential confounders, we found that ICP from both the second and third trimesters could increase the risks of preterm birth, low birth weight(LBW), fetal distress and meconium-stained amniotic fluid.OR values(95% CI) were 6.42(2.59-15.93) and 3.73(2.07-6.72) for preterm birth while 6.52(2.19-19.45) and 4.90(2.43-9.90) for LBW, 2.91(1.27-6.67) and 1.88(1.11-3.19) for fetal distress and 2.34(1.19-4.61) and 1.66(1.11-2.48) for meconium-stained amniotic fluids, respectively.The risk of adverse fetal outcomes caused by the second trimester ICP appeared significantly higher than the third trimester ICP.Conclusion ICP from the second and third trimesters significantly increased the risk of adverse fetal outcomes, suggesting that clinicians should put more attention to the second trimester ICP.Both early detection and intervention were of great importance in reducing the adverse fetal outcomes. |
