Lancet:单克隆抗体risankizumab用于克罗恩病

2017-04-13 MedSci MedSci原创

risankizumab较安慰剂对克罗恩病的临床缓解更为有效,选择性的抑制P19亚基可能是一种阻断IL-23治疗克罗恩病的有效途径

白细胞介素途径与克罗恩病的发病机制有关。研究人员对IL-23 P19亚基、人源单克隆抗体risankizumab的疗效和安全性进行了评估。

在一项随机、双盲、安慰剂对照的II期试验中,招募的患者为年龄18至75岁的、确诊至少3个月的、克罗恩病指数220-450或克罗恩病内镜严重指数至少7级的中重度克罗恩病患者,随机在第0,4,8周接受静脉注射200 mg 、600 mg的 risankizumab或安慰剂。

研究共招募121名患者,其中113人(93%)接受过至少一种TNF抑制剂治疗(96人失败,失败率为79%)。在治疗的第12周,25名接受risankizumab患者(31%)有临床缓解,而安慰剂组为6人(15%)(差异率 15%;95% CI 0.1-30.1)。在41名接受200mg risankizumab以及41名接受600mg risankizumab患者中,分别有10人(24%)和15人(37%)达到临床缓解。共95名(79%)患者出现不良事件(安慰剂组32人;200 mg risankizumab组32人;600 mg risankizumab组31;同下),18人出现中度不良事件(9,6,3),12人终止试验(6,5,1),24人出现严重不良事件(12,9,9)。最常见的不良事件为恶心,最常见的严重不良事件为基础克罗恩病恶化,试验中无患者死亡。

在这项短期的研究中,risankizumab较安慰剂对克罗恩病的临床缓解更为有效,选择性的抑制P19亚基可能是一种阻断IL-23治疗克罗恩病的有效途径。

多层螺旋CT肠道造影在诊断克罗恩病中的应用

克罗恩病(Crohn’s disease)是由美国医生Crohn’s于1932年首先报道的一种至今病因尚不十分清楚的慢性非特异性肠道炎症性疾病,近年来的发病率不断增加,严重影响患者的生活质量。随着影像技术的飞速发展,影像学技术在克罗恩病诊断中的价值越来越高。CT肠道造影为近年来新兴的一种影像学检查方法,因其检查速度快,空间分辨率高而发挥其独特的价值。
