妊娠妇女血清总胆汁酸检测的临床意义
[摘要] 目的:探讨孕妇血清总胆汁酸(TBA)在妊娠过程中的变化。方法:用酶法定量检测孕妇血清中TBA浓度。结果:妊娠早期和晚期孕妇血清中TBA水平都比非妊娠组升高,而且妊娠晚期组比早期组孕妇血清中TBA水平也有明显升高。结论:血清TBA在妊娠过程中持续升高,孕妇在妊娠时就有潜在发生妊娠性肝内胆汁瘀积症(ICP)的危险。

[Abstract] Objective:To investigate the level of total bile acid(TBA) in the serum of women during pregnancy.Methods:The levels of the serum TBA were detected by enzymatic assay.Results:Comparing to the nonpregnant women,the concentrations of the serum TBA of the pregnant women were increased.And the level of the TBA in the late trimester of pregnancy increased significantly comparing to early trimester of pregnancy.Conclusions:In the course of pregnancy,continuous increase of serum TBA level was observed.During normal gestation,symptomless and benign intrahepatic cholestasis occurs.

妇女在妊娠期间,其体内会发生一系列显著的生理变化,主要是受血清中雌激素、孕激素等类固醇的影响,它们在体内的水平随孕期增加而逐渐提高并于晚期达到高峰,这些生理性改变可使肝脏功能发生变化。TBA是反映肝细胞分泌、合成与代谢及肝细胞损害的一个重要指标,也是诊断妊娠肝内胆汁瘀积症(ICP)的敏感指标[1]。本文通过对血清TBA的检测以了解妊娠过程中孕妇血清中TBA的变化。
