目的 研究不同孕周妊娠期肝内胆汁淤积症（ICP）产妇胆汁酸、肝酶、α-羟丁酸脱氢酶（α-HBDH）水平与围产儿结局关系。方法 采用病例对照研究方法,选取孕中期和晚期ICP组、对照组为研究对象。生化仪检测总胆汁酸（TBA）、血清肝酶、α-HBDH水平。高效液相色谱串联质法检测血清内胆酸（CA）、鹅脱氧胆酸、脱氧胆酸（DCA）、石胆酸（LCA）等游离胆汁酸含量。结果 孕中期ICP组血清内CA、DCA、LCA、TBA丙氨酸氨基转移酶（ALT）、天门冬氨酸氨基转移酶（AST）均大于孕晚期组,差异有统计学意义（P<0.05）。多因素Logistic 回归分析结果显示：ALT、AST、a-HBDH、CA、DCA、LCA和TBA升高是围产儿不良结局的危险因素。结论 各类胆汁酸、肝酶、α-羟丁酸脱氢酶对围产儿结局预测价值不同。ALT、AST、a-HBDH、CA、DCA、LCA和TBA升高是围产儿不良结局的危险因素。

目的 分析妊娠期肝内胆汁淤积症(ICP)孕妇与正常孕妇围产结局及ICP孕妇不同总胆汁酸水平对围产结局及新生儿的影响,为做好ICP孕妇的妊娠期管理及其新生儿预后评估提供参考依据。方法 以2010年3月—2020年3月在我院分娩的ICP孕妇 249例为观察组,同期分娩的249例正常孕妇为对照组,比较2组围产结局相关指标。结果 观察组羊水污染、新生儿黄疸、新生儿呼吸窘迫综合征发生率均高于对照组,根据总胆汁酸水平分组,重度组早产、羊水污染发生率高于轻度组,以上差异均有统计学意义(P＜0.05)。总胆汁酸水平是ICP孕妇发生早产的危险因素(P＜0.05)。结论 ICP孕妇总胆汁酸水平可用于发生早产的预测,及时干预有利于提高其围产期质量。

Objective To analyze the perinatal outcome of women with intrahepatic cholestasis of pregnancy (ICP) and normal pregnant women and the effects of different levels of total bile acid in ICP women on perinatal outcome and newborn. To provide a reference for the management of pregnancy and prognosis of ICP women. Methods From March 2010 to March 2020, 249 women with ICP delivered in our hospital were included as the observation group, 249 normal pregnant women delivered in the same period as the control group, the perinatal outcomes of the two groups were analyzed and compared. Results The incidences of amniotic fluid contamination, neonatal jaundice and neonatal respiratory distress syndrome in the observation group were higher than that in the control group. Grouping by the total bile acid level, the incidences of premature delivery and amniotic fluid contamination in the severe group were higher than that in the mild group, with statistical significance (P<0.05). Total bile acid level was a risk factor for premature delivery in women with ICP (P<0.05). Conclusions The level of total bile acid in women with ICP can be used to predict the occurrence of premature delivery, and timely intervention is beneficial to improve the perinatal quality of ICP women.
