NEJM:托法替尼治疗传统类风湿药物无应答的银屑病性关节炎

2017-10-19 zhangfan MedSci原创

研究认为,对于传统类风湿药物无应答的银屑病性关节炎患者,托法替尼表现出良好的症状控制效果,但不良事件率较高

目前口服JK激酶抑制剂托法替尼正在开展银屑病关节炎治疗的临床研究。近日研究人员公布了其对于传统抗风湿药物应答不足的银屑病性关节炎患者的治疗效果。

在为期12个月的双盲对照研究中,患者随机接受每日5mg*2的托法替尼(n=107)、10mg*2的托法替尼 (n=104)、每2周40mg的阿达木单抗 (n=106)、先接受安慰剂后在3个月后转为5mg的托法替尼(n=52)以及先接受安慰剂后在3个月后转为10mg的托法替尼(n=53)。研究的主要终点是达到美国风湿病学院症状20%改善响应(ACR20)的患者比例以及健康评估问卷-残疾指数(HAQ-DI)得分变化。

研究发现,5mg托法替尼组ACR20响应的患者比例为50%,10mg组为61%,安慰剂组为33%,阿达木单抗组为52%。平均HAQ-DI变化,5mg组为-0.35,10mg组为-0.40,安慰剂组为-0.18而阿达木单抗组为-0.38。不良事件发生率如下:5mg组为66%,10mg组为71%,安慰剂组为64-69%,而阿达木单抗组为72%。接受托法替尼治疗的患者中发生了4例肿瘤、3例严重感染以及4例带状疱疹事件。

研究认为,对于传统类风湿药物无应答的银屑病性关节炎患者,托法替尼表现出良好的症状控制效果,但不良事件率较高。

Arthritis Care Res :银屑病性关节炎疾病教育与认识的不足

一项共识声明指出,银屑病性关节炎(PsA)仍有较高比例的患者诊断不足或漏诊。如患者和医师对该疾病加深认识、存在有效的筛查工具、有更加简明的方式确定何时适合转诊至风湿病医师处接受治疗,则可使患者更早接受治疗进而减轻疾病负担。根据美国国立卫生研究院的数据报告,每20个人中就有1名罹患银屑病,并发生PsA。病情较轻的患者仅数个关节受影响,病情严重者可致关节和脊柱僵硬、烧灼感、疼痛。PsA可能增高其他疾病
