研究目的:

胆道闭锁(BA)严重威胁新生儿健康,是导致儿童肝脏移植的首要病因。胆管炎是胆道闭锁术后最常见的并发症,可能与BA患者肠道菌群紊乱,肠道黏膜屏障破坏有关。叶酸在体内发挥重要的生理作用包括维持红细胞的生成以及功能,抑制过氧化反应,减轻炎症反应等。本研究拟探索叶酸改善BA症状,减轻术后胆管炎的有效剂量以及安全性。该研究可以增加对胆道闭锁疾病和治疗的新认识,为循证医学提供良好的科学证据,提高胆道闭锁临床治疗的整体水平。  

Objectives of Study:

Biliary atresia severely threatens health of newborn infants, which is the leading cause of pediatric liver transplantation. Postoperative cholangitis is the most common complication of BA, which is related to microbiome dysbiosis or disruption of mucosal barrier. Folic acid plays an important role in maintaining erythropoiesis, suppressing lipid ROS production and alleviating inflammation. Our study aims to explore effectiveness of folic acid in preventing BA pathogenesis and postoperative cholangitis.

药物成份或治疗方案详述:

无论招募的患者是否随机分配到对照组还是叶酸组,受试者均须进行常规治疗:①对于术前高度疑似BA的患者(治疗方案因不同机构而异,以广州市妇女儿童医疗中心为例):对照组——术前予美能(半片 bid 口服)、丁二磺酸蛋氨酸(50mg/kg qd 静滴)护肝药物,术后予舒普深(80-120mg/kg 每天 静滴)、甲硝唑(7.5mg/次 1天3次 静滴)抗感染、丁二磺酸蛋氨酸(50mg/kg qd 静滴)、美能(半片 bid 口服)、优思弗(10-15mg/kg bid 口服)护肝、止血、补液对症治疗,术后第3-4天开始进食,术后第5-7天开始使用甲强龙静滴治疗(4mg/kg qd 3天,2mg/kg qd 3天),后续甲泼尼龙2mg/k qod 口服治疗3周。叶酸组——在以上治疗的基础上每天补充叶酸(0.4mg/天)。②对于Kasai术后的随访的BA患者:对照组——对症治疗;叶酸组——对症治疗的基础上每天补充叶酸(0.4mg/天)。
