Neurology:EB病毒与抽烟与多发性硬化的活跃或进展无关

2015-10-13 phylis 译 MedSci原创

目的:评估EBV免疫球蛋白G(IgG)抗体水平或者抽烟与单一临床症状(CIS)转化为多发性硬化(MS)或MS进展的相关性。方法:在这项名为BENEFIT临床试验的前瞻性纵向研究中,招募了468名CIS患者,研究人员检测了四个时间点(基线,6月,12月,24月)患者的EBV 的IgG抗体与可替宁(抽烟的生物标志物)水平。预后包括转为临床确诊MS或McDonald MS的时间,复发的人数,扩展残疾状态

目的:评估EBV免疫球蛋白G(IgG)抗体水平或者抽烟与单一临床症状(CIS)转化为多发性硬化(MS)或MS进展的相关性。

方法:在这项名为BENEFIT临床试验的前瞻性纵向研究中,招募了468名CIS患者,研究人员检测了四个时间点(基线、6月、12月、24月)患者的EBV 的IgG抗体与可替宁(抽烟的生物标志物)水平。预后包括转为临床确诊MS或McDonald MS的时间、复发的人数、扩展残疾状态量表(EDSS)改变、脑和T2病灶体积的改变、五年后形成新病灶的人数。校正年龄、性别、治疗配置、基线血浆25羟维生素D水平、T2受损的人数、BMI、EDSS、类固醇治疗及CIS开始类型。

结果:研究人员发现EBV IgG抗体水平及可替宁水平与患者从CIS进展到MS或MS进展无关,应用EDSS或临床活动或MRI判断MS的进展情况。与最低五分之一EBNA-1 IgG水平的相比,最高五分之一的患者从CIS进展到临床诊断MS的相对危险度为1.14(95%CI: 0.76–1.72)。与可替宁水平<10ng/mL 患者相比,可替宁水平>25 ng/mL的患者从CIS进展到临床诊断MS相对危险度为0.96(95%CI:0.71–1.31)。

结论:EBV IgG抗体水平升高包括EBNA-1水平,及因抽烟可替宁水平较高的患者,都与CIS进展到临床诊断为MS、5年随访期间MS活动或进展无关。

Neurology:首次证实EBV病毒与多发性硬化症存在关联

两个EBV病毒颗粒,图片来自维基共享资源。 英国伦敦大学研究人员的一篇新研究表明一种特定病毒如何欺骗免疫系统促发炎症,并对大脑中神经细胞造成伤害,而这些已知能够导致多发性硬化症(multiple sclerosis)。 以前的研究提示着爱泼斯坦-巴尔病毒(Epstein-Barr virus, EBV)与多发性硬化症存在关联,但是它一直充满争议,因为科学家一直不能证实这种关联。 这一新研

摘要号:8562 第一作者:梁超勇,中山大学附属肿瘤医院 标题:早期的阴性循环EB病毒DNA可作为鼻型结外NK/T细胞淋巴瘤(ENKL)的生存预测。 背景:对于具有高侵袭性和不良预后的鼻型结外NK/ T细胞淋巴瘤(ENKL),预测肿瘤标志物是十分必要的。本次的前瞻性研究旨在通过循环EB病毒DNA浓度的动态监测值的评估对ENKL进行预测。 方法:从200
