芝加哥 – 迈阿密大学米勒医学院的Alan W. Heldman, M.D.及其同事开展了一项研究,旨在检查在罹患缺血性心肌病的病人中所做的经心内膜干细胞注射(TESI)自体间充质干细胞和骨髓单核细胞的安全性。 对缺血性心肌病的一种有效的促再生疗法将能解决许多病人的一个主要的未得到满足的需要。根据文章的背景资料,一个悬而未决的问题是,间充质干细胞是否有着类似的安全性及可能比骨髓单核细胞更大的功效

芝加哥 – 迈阿密大学米勒医学院的Alan W. Heldman, M.D.及其同事开展了一项研究,旨在检查在罹患缺血性心肌病的病人中所做的经心内膜干细胞注射(TESI)自体间充质干细胞和骨髓单核细胞的安全性。

对缺血性心肌病的一种有效的促再生疗法将能解决许多病人的一个主要的未得到满足的需要。根据文章的背景资料,一个悬而未决的问题是,间充质干细胞是否有着类似的安全性及可能比骨髓单核细胞更大的功效。

他们在研究中纳入了65名缺血性心肌病患者并对注射间充质干细胞(n=19)加安慰剂(n=11)与骨髓单核细胞(n=19)加安慰剂(n=10)进行了比较及为期1年的随访。主要的检测转归是治疗30天内出现的严重不良事件发生率,不良事件被定义为死亡、心脏病发作、中风、因心衰加剧而住院、穿孔(破裂)、填塞(因为血液或液体的积聚而对心脏的压缩)、或持续性的室性心律失常的复合体。

没有一位病人在治疗到第30天时出现严重的不良反应事件。对1年时严重不良反应事件的探索性分析为:间充质干细胞31.6%,骨髓细胞31.6%,安慰剂38.1%。在一年的时间里,明尼苏达心功能不全生活评分(这是对生活品质的一种检测)中间充质干细胞组及骨髓细胞组皆有改善,但在安慰剂组中则没有改善。只有间充质干细胞组的6分钟行走距离有所增加。

文章的作者写道:“这些结果为进行更大型的研究以提供明确的安全评估及对这一新的治疗方法的功效进行评估提供了基础。”
