JACC:促红细胞生成素并不能为心脏骤停患者带来益处

2016-06-29 fsy 译 MedSci原创

初步数据表明,服用高剂量的促红细胞生成素(Epo)类似物的患者在治疗院外心脏骤停(OHCA)时有临床受益。该研究的目的是在3期临床试验中评估促红细胞生成素α治疗OHCA患者的功效。作者进行了一项多中心,单盲,随机对照试验。假定心脏原因引起的OHCA后仍然昏迷的患者有资格参与此研究。在干预组,患者在第一个48小时期间接受12小时隔开的5次静脉内注射(每次40,000单位,最大总剂量为200,000单

初步数据表明,服用高剂量的促红细胞生成素(Epo)类似物的患者在治疗院外心脏骤停(OHCA)时有临床受益。

该研究的目的是在3期临床试验中评估促红细胞生成素α治疗OHCA患者的功效。

作者进行了一项多中心、单盲、随机对照试验。假定心脏原因引起的OHCA后仍然昏迷的患者有资格参与此研究。在干预组,患者在第一个48小时期间接受12小时隔开的5次静脉内注射(每次40,000单位,最大总剂量为200,000单位),在复苏后尽快开始。在对照组中,患者接受无红细胞生成素的标准治疗。主要终点在60天时是各组患者的脑功能分类(CPC)达到了1级的比例(没有或轻微的神经系统后遗症幸存)。次要终点包括全因死亡率,在不同时间点CPC水平患者的分布,和副作用。

总共有476例患者被纳入了初步分析。基线特征在2组是相似的。在60天时,干预组(76/234)32.4%的患者达到了CPC 1级水平,对照组(78/242)有32.1%的患者达到相应水平(比值比 1.01;95%可信区间: 0.68至1.48)。死亡率和在每个CPC水平患者的比例在各时间点没有差异。对于严重不良事件,在促红细胞生成素治疗的患者中发生的更频繁(22.6% vs 14.9%,P=0.03),特别是血栓形成并发症(12.4% vs 5.8%; 0.01)。

在假定心脏原因引起的OHCA复苏的患者中,早期促红细胞生成素加标准治疗并没有给患者带来临床益处,并有较高的并发症发生率。
