Neurology:COX-2抑制剂与中风死亡率升高相关

2014-11-10 佚名 生物谷

越来越多的研究证实了环氧合酶-2(COX-2)抑制剂对中风患者的危害。最新研究表明,这类药物也与中风死亡率风险升高相关。相关研究结果已发表于11月5日的《神经内科》(Neurology)。丹麦奥胡斯大学医院Morten Schmidt医师领导的团队研究发现,如果患者入院前服用COX-2抑制剂,缺血性中风后30天死亡率升高约20%,但出血性中风后30天死亡率与COX-2抑制剂的使用无相关性。入院时服

越来越多的研究证实了环氧合酶-2(COX-2)抑制剂对中风患者的危害。最新研究表明,这类药物也与中风死亡率风险升高相关。相关研究结果已发表于11月5日的《神经内科》(Neurology)。

丹麦奥胡斯大学医院Morten Schmidt医师领导的团队研究发现,如果患者入院前服用COX-2抑制剂,缺血性中风后30天死亡率升高约20%,但出血性中风后30天死亡率与COX-2抑制剂的使用无相关性。入院时服用常规非选择性非甾体类抗炎药(NSAID)的患者中,缺血性中风或出血性中风死亡率与NSAID的使用无相关性。

Schmidt医师补充称,以往的研究表明,这类药物与较高的心血管事件或中风风险相关。而我们的研究表明,这类药物与脑中风患者较高的死亡率相关。

在这项基于全国人口的队列研究中,研究人员搜索了医学数据库,以确定2004-2012在丹麦所有首次中风住院和随后死亡的患者。NSAID的使用通过追踪处方数据。

结果显示,100043例患者首次中风:51%缺血性卒中,12%脑出血(ICH),5%蛛网膜下腔出血,32%未指定的中风。在这些患者中,10835例(10.8%)是当前NSAID使用者,NSAID使用的有:异丁苯丙酸(51.4%),双氯芬酸(27.0%),依托度酸(10.7%),萘普生(3.2%),塞来昔布(1%),和罗非考昔(0.5%)。

与选择性COX-2抑制剂未使用者相比,当前使用者死于缺血性脑卒中的校正风险比(HR)为1.19(95% CI: 1.02–1.38),这是通过新用户的影响带动(1.42 ,95%CI:1.14-1.77)。倾向得分匹配分析支持了COX-2抑制剂与缺血性脑卒中死亡率之间的关联性。出血性中风死亡率与非选择性NSAID或COX-2抑制剂无相关性。
