Intrahepatic cholestasis of pregnancy is one of the most common liver diseases during the second and third trimesters of pregnancy, but its pathogenesis remains unclear. Intrahepatic cholestasis of pregnancy is associated with elevations of maternal bile acids, serum aminotransferases, and adverse fetal outcomes. Besides direct cytotoxic liver injury by bile acids, it has been suggested that bile acid-induced oxidative stress and mitochondrial injury lead to a cascade of inflammatory responses. Here, we demonstrate that the extended elevation of serum aminotransferases after normalization of bile acid levels coincides with an extended increase of the chemokine CXCL10 and inflammatory cytokines.
妊娠期肝内胆汁淤积症是妊娠中晚期最常见的肝脏疾病之一,但其发病机制仍不清楚。妊娠期肝内胆汁淤积症与母体胆汁酸升高、血清转氨酶升高及不良胎儿结局有关。除了胆汁酸直接导致的细胞毒性肝损伤外,有研究表明胆汁酸诱导的氧化应激和线粒体损伤会引发一系列炎症反应。在此,我们证明胆汁酸水平恢复正常后血清转氨酶的持续升高与趋化因子CXCL10和炎性细胞因子的持续增加相一致。
