J Hepatology: 米多君联合白蛋白在预防等待肝移植的肝硬化患者的并发症中的作用

2018-11-25 MedSci MedSci原创

等待肝移植(LT)的失代偿期肝硬化患者通常会出现可能妨碍他们达到LT标准的并发症。循环功能障碍导致有效的血容量不足和血管收缩系统的激活是肝硬化并发症病理生理学的关键因素。这项研究的目的是探究米多君,一种α-肾上腺素能血管收缩剂与静脉注射白蛋白一起治疗是否能改善循环功能障碍,并预防等待LT的患者出现肝硬化的并发症。

背景与目的
等待肝移植(LT)的失代偿期肝硬化患者通常会出现可能妨碍他们达到LT标准的并发症。循环功能障碍导致有效的血容量不足和血管收缩系统的激活是肝硬化并发症病理生理学的关键因素。这项研究的目的是探究米多君,一种α-肾上腺素能血管收缩剂与静脉注射白蛋白一起治疗是否能改善循环功能障碍,并预防等待LT的患者出现肝硬化的并发症。

方法
研究人员进行了一项多中心,随机,双盲对照试验,纳入了196例肝硬化和腹水的等待LT的患者。患者被随机分配接受米多君(15-30毫克/天)和白蛋白(40克/ 15天)或安慰剂治疗一年,直到患者进行LT。主要观察终点是任何并发症的发生率(肾衰竭,低钠血症,感染,肝性脑病或肠道出血)。次要终点是死亡率,内源性血管收缩系统的活性和血浆细胞因子水平。

结果
两组间随访期间发生肝硬化并发症(p= 0.402)或一年死亡率(p= 0.527)的可能性无显着差异。与安慰剂相比,米多君和白蛋白治疗与血浆肾素活性和醛固酮轻微但显着降低相关(肾素:4.3VS 0.1 ng / ml.h,p<0.001;醛固酮:38?VS6 ng / dl,p= 0.04)。血浆去甲肾上腺素仅在第4周略有下降。动脉压和血浆细胞因子水平均未发生显着变化。

结论
在等待LT的肝硬化患者中,使用用米多君和白蛋白治疗略微抑制血管收缩系统的活性,但不能预防肝硬化并发症或改善生存。
