Previous intracerebral hemorrhage (ICH) is labelled as a contraindication for the use of intravenous tissue plasminogen activator (IV-tPA) in acute ischemic stroke (AIS) based on expert opinion. However, there is a paucity of data available regarding the benefits and risks of IV-tPA in this population. Recent small retrospective cohort studies reporting its off-label use suggest it may be beneficial. This study aims to investigate the safety and efficacy of IV-tPA in AIS patients with previous ICH. We performed a systematic review and meta-analysis of studies reporting on IV-tPA use in AIS patients with and without previous ICH. We searched Embase, PubMed and Cochrane Library from inception to 20 April 2021. Outcomes measured included symptomatic ICH (sICH), 3-month modified Rankin Scale (mRS) score, and 3-month mortality. We included seven retrospective cohort studies comprising 5760 AIS patients who had received IV-tPA, of which 134 had previous ICH. There was no significant difference in the odds of sICH (OR 1.57, 95% CI 0.78-3.15, p = 0.21) and 3-month mRS (mRS 0-1: OR 0.78, 95% CI 0.37-1.65, p = 0.52; mRS 0-2: OR 1.07, 95% CI 0.36-3.15, p = 0.90) between patients with and without previous ICH. There was a trend towards higher 3-month mortality in patients with previous ICH (OR 1.69, 95% CI 0.98-2.91, p = 0.06), although this did not reach statistical significance. The use of IV-tPA in AIS patients with previous ICH was not associated with an increased risk of sICH or disability at 3 months. Further larger studies are needed to establish the safety and efficacy of IV-tPA use in this population.
基于专家意见,既往有脑出血(ICH)被列为急性缺血性卒中(AIS)患者静脉使用组织纤溶酶原激活剂(IV-tPA)的禁忌证。然而,关于IV-tPA用于这一人群的获益和风险,现有数据较少。近期一些报告其超说明书使用情况的小型回顾性队列研究表明,它可能是有益的。本研究旨在调查IV-tPA用于既往有ICH的AIS患者的安全性和有效性。我们对报告IV-tPA用于有或无既往ICH的AIS患者的研究进行了系统评价和荟萃分析。我们检索了自建库至2021年4月20日的Embase、PubMed和Cochrane图书馆。测量的结局包括症状性脑出血(sICH)、3个月改良Rankin量表(mRS)评分和3个月死亡率。我们纳入了7项回顾性队列研究,共5760例接受IV-tPA治疗的AIS患者,其中134例有既往ICH。有或无既往ICH的患者在发生sICH的几率(比值比[OR]1.57,95%置信区间[CI]0.78 - 3.15,p = 0.21)和3个月mRS评分(mRS 0 - 1:OR 0.78,95%CI 0.37 - 1.65,p = 0.52;mRS 0 - 2:OR 1.07,95%CI 0.36 - 3.15,p = 0.90)方面无显著差异。既往有ICH的患者3个月死亡率有升高趋势(OR 1.69,95%CI 0.98 - 2.91,p = 0.06),尽管未达到统计学显著性。IV-tPA用于既往有ICH的AIS患者与3个月时sICH风险增加或残疾无关。需要进一步开展更大规模的研究来确定IV-tPA用于这一人群的安全性和有效性。
