Hepatology:门脉压力指导治疗预防曲张静脉再出血改善预后:一项随机对照研究

2017-04-02 MedSci MedSci原创

背景:监测门脉压力对药物治疗的动态变化可准确区分静脉曲张再发出血的风险。我们评估通过肝静脉压力梯度(HVPG)监测指导治疗是否可预防静脉曲张再出血,从而改善预后。方法:可控的静脉曲张出血的肝硬化患者被随机分配到HVPG指导治疗组(84人)或对照组(86人)。在两组基线水平评估HVPG和快速β阻滞剂反应,每2-4周测量HVPG来观察其长期反应。在HVPG指导治疗组,急性β受体阻滞反应者使用纳多洛尔治

背景:监测门脉压力对药物治疗的动态变化可准确区分静脉曲张再发出血的风险。我们评估通过肝静脉压力梯度(HVPG)监测指导治疗是否可预防静脉曲张再出血,从而改善预后。

方法:可控的静脉曲张出血的肝硬化患者被随机分配到HVPG指导治疗组(84人)或对照组(86人)。在两组基线水平评估HVPG和快速β阻滞剂反应,每2-4周测量HVPG来观察其长期反应。在HVPG指导治疗组,急性β受体阻滞反应者使用纳多洛尔治疗,急性β受体阻滞无反应者使用纳多洛尔+硝酸盐药物。长期无反应者接受纳多洛尔+哌唑嗪治疗,接受第三个HVPG研究:反复进行结扎直到出现反应。对照组使用纳多洛尔+硝酸盐+结扎治疗。

结果:两组间基线特征相似。在长期随访中(中位时间24个月),HVPG指导治疗组死亡率比对照组要低(29% VS 43%,风险比0.59,95%置信区间0.35-0.99)。两组再发出血率分别为19%和31%(风险比0.53,95%置信区间0.29-0.98),慢性无反应者(分相比0.48,95%置信区间0.23-0.99)。HVPG指导治疗患者HVPG降低幅度更大,最终水平比对照组低(P小于0.05)。

结论:通过风险分层及针对性治疗,使用最新推荐的β受体阻滞剂和结扎方法,HVPG检测指导治疗可提高存活率。HVPG指导治疗实现了门脉压力更大幅度的降低,与再出血和肝硬化失代偿风险的降低相关,因而达到更好的存活率。
