NEJM:异丁司特可减慢进展性多发性硬化患者脑萎缩进程

2018-08-30 zhangfan MedSci原创

研究认为异丁司特可减慢进展性多发性硬化病程,减缓脑萎缩速度

目前进展性多发性硬化的治疗方法十分有限,异丁司特可抑制多种环核苷酸磷酸二酯酶、巨噬细胞迁移抑制因子和Toll样受体4,并能跨越血脑屏障,对进行性多发性硬化具有潜在的治疗作用。

近日研究人员开展II期研究,考察异丁司特(≤100 mg/每天)对原发性或继发性进行性多发性硬化的治疗效果。研究的主要终点为脑实质分数评估的脑萎缩率。次要终点包括扩散张量成像上锥体束、脑组织磁化传递比、视网膜神经纤维层的厚度和皮质萎缩变化。

255名患者参与研究,其中异丁司特治疗组129人,安慰剂组126人,原发性进行性多发性硬化患者比例为52%,其余为继发性患者。异丁司特治疗组患者脑实质分数变化率为每年减少0.001,对照组为0.0019,相当于治疗96周后,异丁司特治疗组患者脑体积减少量较安慰剂组低2.5mL。治疗导致的不良反应包括肠道症状、头痛和抑郁。

研究认为异丁司特可减慢进展性多发性硬化病程,减缓脑萎缩速度。
