Neurology:静脉溶栓和血小板计数!

2018-01-26 xing.T MedSci原创

由此可见,PC下降与sICH发病风险增加有关,PC越高表明死亡率越高。该研究的数据表明,PC可改变患者的结果和并发症,而对所有PC<100×109/L患者停止IVT仍具有挑战性。

近日,神经病学领域权威取杂志Neurology上发表了一篇研究文章,该研究旨在调查血小板计数(PC)对接受静脉溶栓(IVT)治疗的脑卒中患者出血风险和预后的影响,并探讨是否支持PC<100×109/L后停止IVT。

在前瞻性多中心IVT登记研究中,研究人员比较了症状性颅内出血(sICH;根据第二次欧洲-澳大利亚急性脑卒中研究[ECASS II]标准)的PC、预后不良(改良Rankin量表3-6分)和3个月死亡率。PC被作为连续和分类变量来区分血小板减少症(<150×109/L)、血小板增多症(>450×109/L)和正常PC(150-450×109/L [参照组])。此外,PC<100×109/L与PC≥100×109/L相比,研究人员采用logistic回归模型计算了未调整和调整后的比值比(OR)与95%可信区间(CI)。

在7533例接受IVT治疗的脑卒中患者中,6830例(90.7%)患者PC正常,595例(7.9%)患者为血小板减少症,108例(1.4%)患者为血小板增多症。降低PC(每10×109/L)与sICH风险增加有关(调整后OR为1.03,95%CI为1.02-1.05),但预后不良(OR为0.99,95%CI为0.98-0.99)和死亡(OR为0.99,95%CI为0.98-0.99)的风险降低。血小板减少症患者的sICH风险高于正常PC患者(OR为1.73,95%CI为1.24-2.43)。然而,不良结局(调整后的OR为0.89,95%CI为0.39-1.97)和死亡(调整后的OR为1.09,95%CI为0.83-1.44)风险没有显著差异。血小板增多症与死亡率相关(调整后的OR为2.02,95%CI为1.21-3.37)。四十四例(0.3%)患者PC<100×109/L,其sICH(OR为1.56,95%CI为0.48-5.07)、预后不良(OR为1.63,95%CI为0.82-3.24)和死亡率(OR为1.38,95%CI为0.64-2.98)的风险与PC≥100×109/L的患者差异无统计学意义。

由此可见,PC下降与sICH发病风险增加有关,PC越高表明死亡率越高。该研究的数据表明,PC可改变患者的结果和并发症,而对所有PC<100×109/L患者停止IVT仍具有挑战性。

Neurology:应该拒绝痴呆患者静脉溶栓吗?

痴呆不是急性缺血性卒中溶栓的禁忌症,但是大部分溶栓研究都把80岁或90岁以上患者排除在外,当前溶栓指南对这些患者的推荐意见存在差异

Stroke:SSRI与静脉溶栓的安全性

选择性血清素再摄取抑制剂(SSRI)是治疗焦虑和抑郁症的一线药物。但是,SSRI与严重出血事件之间的关系一直受到关注,特别是合并使用抗栓药物的患者。SSRI增加出血风险的机制:SSRI降低血小板释放血清素的数量,后者对血小板的聚集起着重要作用。很多研究发现SSRI与消化道出血有关,但是SSRI与脑出血的关系一直受到关注,因为有研究发现SSRI增加脑微出血的风险。不过,观察性研究和最近大型基于人

Stroke:外科手术后静脉溶栓的安全性

4.5h内rtPA静脉溶栓能够改善急性缺血性卒中的预后。静脉溶栓有很多禁忌症,其中一些是具有争议的。比如一些禁忌症被广泛研究后发现是相对禁忌症,比如既往卒中合并糖尿病、近3个月内卒中、年龄超过80岁以及NIHSS<4或>25。然而,其他一些禁忌症的临床意义仍然具有争议,因为缺乏相关研究数据,比如手术后卒中。手术后卒中采取静脉溶栓被认为会增加手术部位出血的风险。美国FDA说明书把“最近大手术”,欧洲

Neurology:>80岁3-4.5h时间窗是否应该静脉溶栓?

急性缺血性卒中RCT汇总分析显示静脉溶栓(IVT)对于年龄>80岁与年龄18-80岁的疗效是相似的。对于3-4.5h的时间窗,年轻患者的获益具有显著性(OR 1.26, 95% CI 1.04–1.54),但是老年患者的获益未达到独立显著性;不过,老年患者的样本量较小,并且显示一定程度获益(OR 1.36, 95% CI 0.87–2.14)。6h内治疗延迟将减弱IVT的获益,并且未相应增加s
