Lancet:去氨普酶治疗重度缺血性卒中后3-9h安全性和有效性评估

2015-05-04 崔倩 译 MedSci原创

目前溶栓治疗缺血性卒中发病后限制为3〜4.5小时。我们的目的是评估去氨普酶的安全性和有效性,一种纤维蛋白依赖性纤溶酶原激活剂,在主要脑动脉患者闭塞或重度狭窄症状出现后3-9小时治疗。    在一项前瞻性,双盲,多中心,平行组,随机试验中,我们从17个国家77家医院招募那些曾在大型脑动脉缺血性脑卒中和闭塞或重度狭窄的患者参加试验。我们随机分配患者以1:1的比例,使用计算

目前溶栓治疗缺血性卒中发病后限制为3〜4.5小时。我们的目的是评估去氨普酶的安全性和有效性,一种纤维蛋白依赖性纤溶酶原激活剂,在主要脑动脉患者闭塞或重度狭窄症状出现后3-9小时治疗。
    
在一项前瞻性,双盲,多中心,平行组,随机试验中,我们从17个国家77家医院招募那些曾在大型脑动脉缺血性脑卒中和闭塞或重度狭窄的患者参加试验。我们随机分配患者以1:1的比例,使用计算机生成的随机列表与基线国家卫生院卒中量表和年龄分层,症状发作后接受去氨普酶(90微克/公斤)或3-9小时或接受安慰剂治疗。患者,调查人员,工作人员和资助者均不知道治疗分配。主要成果是一个有利的改良Rankin量表评分在90天的时候(0-2),所有治疗的患者在改良Rankin量表中的至少一个基线后测量。安全评估在所有接受研究药物随机分配的患者中进行。
    
在2009年2月6日和2013年11月27日之间,我们招收了492例患者随机分配247例接受去氨普酶,245例接受安慰剂(去氨普酶组中的236例和安慰剂组中的237被列入了主要终点的分析)。安慰剂组从卒中发病到治疗平均时间为6.9小时(IQR 5.7-8.0),去氨普酶组为7.0小时(6.0-7.9)。改良Rankin量表评分(0-2)在90日发生的是去氨普酶组的121(51%)例患者,安慰剂组为118例(50%)(调整后的比值比为1.20,95%Cl 0.79-1.81, p=0.40)。240例在去氨普酶组中24例患者(10%)死亡,238例患者安慰剂组中23例(10%)死亡。240例患者接受去氨普酶有64例发生(27%)严重不良事件,而238例患者接受安慰剂组有69例(29%);症状性颅内出血(去氨普酶组中6例患者[3%] VS 安慰剂组中5例患者[2%]),症状性脑水肿(5[2%]VS [2%)],大出血(10[4%] VS 15[6%]),多治疗组之间是相同的。
    
去氨普酶治疗没有引起安全问题,但当治疗缺血性卒中和主要脑动脉闭塞超越症状发作超过3小时的患者时没有改善功能。
