The Tranexamic acid for IntraCerebral Haemorrhage-2 (TICH-2) trial reported no significant improvement in death and dependency at day 90 despite reductions in haematoma expansion, early neurological deterioration and early death. However, significant recovery after stroke, particularly intracerebral haemorrhage (ICH), may take more than 3 months. Here we report the participant outcomes at 1 year after stroke.
TICH-2 was a prospective randomised controlled trial that tested the efficacy and safety of tranexamic acid in spontaneous ICH when given within 8 h of onset. Patients with ICH on anticoagulation were excluded. Centralised blinded telephone follow up was performed for patients from the United Kingdom at 1 year. The primary outcome was modified Rankin Scale at 1 year. Secondary outcomes included Barthel index, Telephone Interview Cognitive Status-modified, EuroQoL-5D and Zung Depression Scale. This was a prespecified secondary analysis of the TICH-2 trial.
About 2325 patients were recruited into the trial (age 68.9 ± 13.8 years; 1301 male, 56%). About 1910 participants (82.2%) were eligible for day 365 follow up. 57 patients (3.0%) were lost to follow up. Tranexamic acid did not reduce the risk of poor functional outcome at 1 year (adjusted OR 0.91 95% CI 0.77-1.09; = 0.302). However, Cox proportional hazard analysis revealed significant survival benefit in the tranexamic acid group (adjusted HR 0.83, 95% CI 0.70-0.99; = 0.038).
There was no difference in functional outcome at 1 year after ICH. Tranexamic acid may reduce mortality at 1 year without an increase in severely dependent survivors. But this should be interpreted with caution as this is a result of secondary analysis in a neutral trial.
尽管氨甲环酸可减少脑出血扩展、早期神经功能恶化和早期死亡,但脑出血-2(TICH-2)试验报告显示,在第90天时,患者的死亡和依赖情况并无显著改善。然而,中风(尤其是脑出血)后的显著恢复可能需要3个月以上的时间。在此,我们报告中风后1年时参与者的结局。
TICH-2是一项前瞻性随机对照试验,旨在测试氨甲环酸在脑出血发病8小时内给药时的疗效和安全性。排除正在接受抗凝治疗的脑出血患者。对来自英国的患者进行了为期1年的集中盲法电话随访。主要结局指标是1年时的改良Rankin量表。次要结局指标包括Barthel指数、电话访谈认知状态改良版、欧洲五维健康量表和zung抑郁量表。这是对TICH-2试验预先设定的次要分析。
约2325名患者被纳入试验(年龄68.9±13.8岁;男性1301名,占56%)。约1910名参与者(82.2%)符合第365天随访条件。57名患者(3.0%)失访。氨甲环酸并未降低1年时功能结局不良的风险(校正比值比0.91,95%置信区间0.77-1.09;P=0.302)。然而,Cox比例风险分析显示氨甲环酸组有显著的生存获益(校正风险比0.83,95%置信区间0.70-0.99;P=0.038)。
脑出血后1年时功能结局无差异。氨甲环酸可能降低1年时的死亡率,且不会增加严重依赖幸存者的数量。但由于这是一项中性试验的次要分析结果,因此应谨慎解读。
