Lancet Neurol:Daclizumab能明显降低多发性硬化症(MS)的复发(SELECTION研究)

2014-06-23 MedSci MedSci原创

Daclizumab(赛尼派),一种用于预防肾移植排斥反应的药物,主要作用于CD25受体而抑制免疫系统,但是2009年因业绩不佳而停止销售这款药物。最近一项研究为Daclizumab(赛尼派)带来新的生机,能明显降低多发性硬化症(MS)的复发。这项被命名为SELECT的试验中,由于全球74个中心参与其中,纳入患者18-55岁,复发的多发性硬化患者,患者起始皮下注射150mg和300 mgDacli

Daclizumab(赛尼派),一种用于预防肾移植排斥反应的药物,主要作用于CD25受体而抑制免疫系统,但是2009年因业绩不佳而停止销售这款药物。最近一项研究为Daclizumab(赛尼派)带来新的生机,能明显降低多发性硬化症(MS)的复发。

这项被命名为SELECT的试验中,由于全球74个中心参与其中,纳入患者18-55岁,复发的多发性硬化患者,患者起始皮下注射150mg和300 mgDaclizumab,每4周一次,连续52周。接受Daclizumab治疗的患者被随机分为两组,一组为连续治疗组,另一组进行洗脱20周然后重新用药。最终567位患者中有91%(517例)完成了SELECT试验,这些患者进入SELECTION,170例为起始处理组,173例为连续处理组,174例为洗脱重启组。这三组中分别观察到11例(6%),13例(8%)和10例(6%)出现严重不良事件。在洗脱重启组有1例因为严重的自身免疫性肝炎出现死亡。7例患者发现体内出现药物的中和抗体。在研究的第二年,未见自身免疫性肝炎的增加。这项研究总体来说,达到良好的疗效,但是一些严重不良事件,为研究带来阴霾。

实际上,同期进行的另一项3期研究(DECIDE研究)结果也相似。这项研究由1800多名复发缓解型多发性硬化症患者参与,一月注射一次Daclizumab和一周注射一次Avonex(干扰素β-1a粉针剂)用于多发性硬化症治疗进行了检测。

Daclizumab用药患者与Avonex用药患者相比,年复发率降低45%。此外,在研究进行到第96周时,Daclizumab用药患者与Avonex用药患者相比,新的或扩大的脑及脊髓损伤减少了54%,这些结果达到了研究的次要目标。两组患者的副作用总发生率相似。但Daclizumab用药组有更高的严重感染发生率(4%),同时肝酶异常的比例也更高,而这是肝毒性的一种潜在信号。Daclizumab如果获批用于这种疾病的话,它将成为多发性硬化症的一种新治疗选择。

Nature:再生疗法治疗多发性硬化症

斯克里普斯研究所(The Scripps Research Institute,TSRI)科学家发现了一组能够用于治疗多发性硬化症(multiple sclerosis,MS)的药物。与显存治疗MS药物的机制不同,该新药物能够激活一组前体细胞用来修复MS中遭到破坏的神经纤维。 该发现的新药包括一种治疗PD的药物benztropine,该药单独治疗或结合其他MS疗法治疗

Diabetes Care:青少年DM患者多发性硬化症发病风险高

在儿童及青少年中,1型糖尿病和多发性硬化症(MS)是典型的自身免疫性疾病。为了评价1型糖尿病并发MS的情况(通过估计儿童和青少年糖尿病人群的MS相对风险来进行),并寻找可能的影响因素,来自德国慕尼黑大学医学院儿科的Bechtold博士等进行了一项研究,研究发现,儿童和青少年糖尿病人群并发MS的风险较高。移民背景和甲状腺抗体是预测MS发病率的独立风险指标,环境因素可调节个人并发这两种疾病的风险。研究

JAMA Neurol:血清维生素D水平是MS病情有力的预测指标

美国哈佛大学公共卫生学院的Alberto Ascherio博士等人在一项为期5年的应用贝他弗隆治疗多发性硬化症初治患者的随访研究(BENEFIT)中发现,在多发性硬化症(MS)患者中,高维生素D水平与患者较低的病情活动度、核磁共振成像损伤程度、脑萎缩及疾病进展相关。研究结果在线发表在2014年1月的JAMA Neurol杂志上。 465例具有孤立临床症状(首次神经学症

PNAS :维生素D有望治疗多发性硬化症

Johns Hopkins大学的一项研究显示,在多发性硬化症MS的小鼠模型中,维生素D能够阻止破坏性免疫细胞移动到中枢神经系统,从而防止或减轻相关疾病症状。文章于十二月九日发表在美国国家科学院院刊PNAS杂志上。 此前人们曾发现,在远离赤道日照少的地方MS更为普遍,而阳光是维生素D的天然来源。现在,这项研究解释了这一现象,阐明了维生素D对MS的有益影响。 “研究

Lancet:他汀类药物或可治疗多发性硬化症(MS-STAT研究)

英国医学杂志《柳叶刀》网站19日刊登一项新成果说,主要用于降血脂的他汀类药物可能对多发性硬化症患者有益,帮助他们减缓脑萎缩,缓解相关病情。 多发性硬化症是造成瘫痪的一大病因,患者大脑和脊髓中的神经受损,导致运动能力、平衡能力和视力下降。据介绍,约有一半患者在患病约10年后,进入症状更为严重的后期阶段,目前尚没有专用药物能有效缓解这一阶段的病情。 英国伦敦大学学院等机构的研究人员报告说,他们共征

PLoS One:神经影像技术揭示多发性硬化症个体认知损伤的分子机制

近日,来自凯斯勒基金会的研究者通过研究,揭示了多发性硬化症(MS)个体认知疲劳发生的分子机制,相关研究刊登于国际杂志PLoS ONE上,这项研究首次使用神经影像技术来调查研究个体的认知疲劳发生的过程。【原文下载】 认知疲劳源于脑力劳动,这项研究中,研究者利用三种神经影像技术来揭示和MS个体认知疲劳相关的神经回路,第一种方法是功能性磁共振成像(fMRI)技术,其可以帮助
