根据2016年10月12日在线在Neurology®的一项新研究发现,用于治疗多发性硬化症(MS)的药物阿仑单抗(alemtuzumab)可逆转该疾病导致的一些身体残疾。由于它可以导致严重的副作用,阿仑单抗通常用于对其他MS药物没有良好反应的人群;然而,在这项研究中,它在MS过程中应用的相对较早。

该药用于治疗复发缓解型MS,这是该疾病的最常见形式,在该疾病中,症状在突然恶化和缓解之间交替发生。

该研究的作者,伦敦玛丽女王大学Gavin Giovannoni博士说:“虽然许多MS药物减缓了残疾的进展,但目前几乎没有关于目前治疗方法帮助恢复以前失去功能的数据。”

在该研究中,对其他至少一种MS药物没有良好反应的复发缓解型MS患者接受阿仑单抗(426人)或药物干扰素β-1a(202人)治疗。

研究人员在研究开始时和每三个月评估参与者的残疾程度,为期两年。到研究结束时,阿仑单抗组近28%的受试者在残疾测试中改善了至少一个点,该测试的得分范围从0到10,而接受干扰素的受试者改善一个点的比例为15%。接受阿仑单抗的人思维技能评估改善的可能性是接受干扰素的人的2.5倍,并且无震颤或笨拙运动(称为共济失调)的移动能力改善可能性提高两倍以上。研究人员调整了结果,以确保这些改善的结果不是由最近的复发恢复的人造成的。

Giovannoni指出,如果证实了阿仑单抗的好处,还需要考虑其风险,包括严重和很少致命的自身免疫问题以及输液反应的风险。

“这些结果是令人鼓舞的,但是alemtuzumab是如何可以逆转损伤的,无论是通过修复髓磷脂,产生新的神经突触,还是大大减少了炎症或一些其他机制,还尚未被调查,”美国国家神经疾病和中风研究所的医学博士Bibiana Bielekova说。“我们还需要更长时间的研究来了解有多少人在更长的时间内经历或没有经历过残疾改善。”
