研究目的: |
ICP的一线用药物为熊去氧胆酸联合s-腺苷蛋氨酸,但近期荟萃分析均发现熊去氧胆酸并未发现可明显改善胎儿或新生儿妊娠结局,且s-腺苷蛋氨酸虽可降低剖宫产率、延长孕周,但停药存在反弹。因ICP对围产儿不良结局影响所带来的医疗,经济,家庭负担较大,同时尚无有效的治疗方案,故探索ICP导致胎儿不良结局的发病机制,并以此为基础,寻找新的有效治疗方案,降低胎儿及新生儿不良结局将成为我们临床医生共同努力解决的目标。目前国内外均未见NLRP3炎症小体通过细胞焦亡在ICP发病机制中的研究报道,该研究具有前瞻性和创新性。 |

Objectives of Study: |
Ursodeoxycholic acid (UDCA) combined with S-adenosylmethionine (SAMe) constitutes the first-line pharmacotherapy for intrahepatic cholestasis of pregnancy (ICP). However, recent meta-analyses have demonstrated that UDCA does not significantly improve fetal or neonatal outcomes. Although SAMe has been shown to reduce the cesarean section rate and prolong gestational duration, a rebound phenomenon occurs upon treatment discontinuation. Given the substantial medical, economic, and familial burdens imposed by adverse perinatal outcomes associated with ICP, along with the current lack of effective therapeutic interventions, elucidating the pathogenesis underlying ICP-induced adverse fetal outcomes, and on this basis identifying novel and effective treatment strategies to reduce fetal and neonatal complications, represents a critical goal that clinicians must collectively strive to achieve. To date, no studies—either domestically or internationally—have reported on the involvement of the NLRP3 inflammasome in the pathogenesis of ICP via pyroptosis. Therefore, the present study is both prospective and innovative. |
