Lancet:Tocilizumab治疗巨细胞动脉炎的有效性

2016-03-08 MedSci MedSci原创

背景:巨细胞动脉炎是一种免疫介导的大中动脉疾病,常影响50岁以上人群。糖皮质激素治疗是金标准,可预防严重血管并发症,但也与大量的死亡率和发病率相关。托珠单抗(Tocilizumab),一种抗人白介素6(IL-6)受体抗体,可快速反应并缓解巨细胞动脉炎。我们开展了首个随机临床试验研究tocilizumab在新近诊断或复发性巨细胞动脉炎患者中的安全性和有效性。方法:单中心,随机,双盲,安慰剂对照试验,

背景:巨细胞动脉炎是一种免疫介导的大中动脉疾病,常影响50岁以上人群。糖皮质激素治疗是金标准,可预防严重血管并发症,但也与大量的死亡率和发病率相关。托珠单抗(Tocilizumab),一种抗人白介素6(IL-6)受体抗体,可快速反应并缓解巨细胞动脉炎。我们开展了首个随机临床试验研究tocilizumab在新近诊断或复发性巨细胞动脉炎患者中的安全性和有效性。

方法:单中心,随机,双盲,安慰剂对照试验,招募了伯尔尼大学医院、瑞士的50岁及以上患者,符合1990年美国风湿病学院巨细胞动脉炎的诊断标准。新发或复发的患者被随机分配(2:1)到接受tocilizumab (8 mg/kg)或静脉注射安慰剂组。每隔4周注射13次,直到第52周。两组均接受口服强的松,起始剂量为1mg/kg/天,根据研究草案规定的标准减量方案逐渐减少到0。根据计算机排列设计随机分配到治疗组,并分成三个板块,临床试验单元由计算机随机分配产生。主要结局终点是12周口服强的松剂量为0.1mg/kg/天时达到疾病完全缓解的病人的比例。所有的分析都是意向性治疗。

结局:2012年3月3日-2014年9月9日,20名患者被随机分配到接受tocilizumab和强的松,10个病人接受安慰剂和糖皮质激素;分别有16个(80%)和7个(70%) 病人有新发和复发性的巨细胞动脉炎。12周完全缓解数分别为tocilizumab组17(85%)/20人,安慰剂组4(40%)/10人(风险差异45%,95% CI 11 - 79;p = 0.0301)。52周无复发生存分别为17人(85%)和2人(20%)(风险差异65%,95% CI 36 - 94;p = 0.0010)。停用糖皮质激素平均生存时间差异,tocilizumab组多出12周(95% CI 7–17; p<0.0001),52周强的松累积剂量为tocilizumab组43 mg/kg VS 安慰剂组110 mg/kg,(p=0.0005),严重不良事件发生分别为7人(35%)VS 5人(50%)。

我们的研究通过首个临床试验表明了tocilizumab对于治疗巨细胞动脉炎和维持缓解的有效性。

NEJM: Tocilizumab可有效治疗全身性幼年型特发性关节炎

全身性幼年型特发性关节炎(JIA)是JIA最严重的亚型,治疗选择有限,白介素(IL)-6在全身性JIA中具有致病作用。意大利罗马大学De Benedetti博士等人对此进行了深入研究,他们发现,Tocilizumab治疗严重的持续性全身性JIA有效。不良事件常见,包括感染、中性粒细胞减少和转氨酶水平升高。相关论文发表于国际权威杂志NEJM 2012年12月20日在线版。 研究人员对112例年龄为

Lancet:循证医学发现阻断IL6受体可能用于冠心病防治

近日,国际权威医学期刊《柳叶刀》The Lancet在线刊登了两项国际大规模荟萃分析(meta-analyses)研究成果,在这两篇论文中研究人员发布了令人注目的新数据,证实一种参与炎症信号通路的蛋白——白介素-6受体(IL6R)是冠状动脉心脏病(简称冠心病,CHD)的致病原因。这些研究发现表明靶向特异性炎症机制(例如IL6R介导的信号通路)的药物或许也能有效防治冠心病。当前有一种这样的药物toc

Tocilizumab治疗RA有效

来源:医学论坛网   日本一项最新研究表明,在日常临床实践中,tocilizumab对确诊RA患者表现出优良的疗效。该研究论文7月13日在线发表于《风湿病学》(Rheumatology)杂志。   本研究连续纳入使用tocilizumab的232例RA患者,观察52周。患者年龄平均为59.1岁,病程平均为12.4年,28关节疾病活动性评分(DAS28)均值为5.6。尽管62.8%患者曾接受抗肿
