Circ Res:外周动脉疾病自体细胞治疗的疗效如何?

2017-01-20 xing.T MedSci原创

虽然这项荟萃分析强调了需要更高质量的安慰剂对照试验,平衡可能不再被保证,因为自体细胞治疗具有调整难治性CLI自然病史的潜力。

严重肢体缺血(CLI)是外周动脉疾病(PAD)威胁生命的并发症。对于不适合接受血运重建术的患者,因很少有替代的治疗方案,常常会导致截肢和死亡。近日,心血管领域权威杂志Circulation Research上发表了一篇荟萃分析,研究者旨在评估难治性PAD/CLI进行自体细胞治疗的疗效和安全性。

研究人员检索了19个随机对照试验(RCTs;共有837例患者)、7个非随机对照试验(共有338例患者)和41个非对照研究(共有1177例患者)。该荟萃分析的主要终点是主要肢体截肢。

这些纳入的研究异质性高,不能排除发表偏倚。尽管有这些局限性,初步分析(所有RCTs)显示细胞治疗可以降低截肢37%的风险,无截肢生存率可以提高18%,可改善59%的伤口愈合,而不影响死亡率。细胞治疗显著增加ABI、TcO2和减少静息痛。次要分析(所有对照试验,n=1175例)显示每2名成功治疗的患者有就有可能是避免将近1次截肢/年。第三分析(所有研究;n=2332例)准确地估计了细胞治疗后ABI、TcO2、静息痛和行走能力的变化情况。肌肉内植入明显比动脉内输入更有效,并且动员的外周血单个核细胞(MNC)可能超越骨髓来源的MNCs和间充质干细胞。截肢率在糖尿病患病率较高的试验中改善的更多,细胞治疗与严重不良事件无关。值得注意的是,在安慰剂对照的RCTs中细胞治疗对所有终点的效应不再显著,而在偏倚风险较低RCTs中细胞治疗对所有终点的效应则消失。

由此可见,虽然这项荟萃分析强调了需要更高质量的安慰剂对照试验,平衡可能不再被保证,因为自体细胞治疗具有调整难治性CLI自然病史的潜力。

在之前有过心肌梗死(MI)的患者中,外周动脉疾病(PAD)与缺血性和出血风险增加有关。这项研究评估了在PAD和之前有过MI的患者中,替卡格雷治疗对于主要心血管(CV)事件和重大不良肢体事件的疗效性和安全性。PEGASUS-TIMI54研究随机分配21162例之前有过MI(1〜3年)的患者接受替卡格雷90毫克每天两次,替卡格雷60毫克,每天两次,或安慰剂,所有都以低剂量阿司匹林为背景。是否有PAD的

JACC: 伴有心肌梗死的PAD患者,应用替卡格雷进行二级预防有效可行

背景:外周动脉疾病(PAD)与存在心肌梗死史(MI)患者较高的缺血和出血风险有关。目的:在PEGASUS-TIMI 54这一试验中,研究者评估存在心肌梗死史的PAD患者,应用替卡格雷治疗对主要心血管事件和不良的上肢事件的有效性和安全性。方法:PEGASUS-TIMI 54将21162名存在心肌梗死的患者随机分为,替卡格雷90 mg治疗组,60 mg治疗组或安慰剂组,所有患者都给予低剂量的阿司匹林。

JAMA Surg:指南推荐降低风险计划降低外周动脉疾病患者心血管事件的发生

重要性:外周动脉疾病患者(PAD)是心血管事件的高风险因素,但没有研究调查综合风险降低计划对PAD患者长期预后的影响。目标:调查一项针对8个主要指南推荐危险因素管理方法的项目是否可以降低PAD患者心血管事件和肢体事件。设计,设置和参与者:2004年7月1日和2013年3月31日其间,加拿大的研究者使用加拿大,安大略行政数据库中的数据,进行了一项长达7年随访的观察性队列研究。2004年7月至2007
