  牛皮癣(也叫银屑病)是一种因皮肤细胞变异而导致皮肤红肿的疾病,不同的患者牛皮癣的严重程度并不相同。一直以来,这种疾病没有治愈的方法。不过,最近美国科学家们开发出一种新的药物可能能够改变这一现状。 经过长期的临床试验,70%-80%的牛皮癣患者能够完全治愈,这是十分令人惊喜的结果。 该药物叫做“ixekizumab”,将能够解决世界上3%人群的心头之患。 牛皮癣患者需要面

 

牛皮癣(也叫银屑病)是一种因皮肤细胞变异而导致皮肤红肿的疾病,不同的患者牛皮癣的严重程度并不相同。一直以来,这种疾病没有治愈的方法。不过,最近美国科学家们开发出一种新的药物可能能够改变这一现状。

经过长期的临床试验,70%-80%的牛皮癣患者能够完全治愈,这是十分令人惊喜的结果。

该药物叫做“ixekizumab”,将能够解决世界上3%人群的心头之患。

牛皮癣患者需要面对的不仅仅是皮肤的刺激反应以及生理性的损伤,而且还有相应的抑郁、心脏病以及糖尿病等附加疾病。

“该研究不仅仅展示了这种药物的高效性以及安全性,而且药性能够维持60个星期之久”,研究者之一来自西北大学医学院的皮肤科学家Kenneth Gordon 说到。

这一研究的过人之处在于其庞大的样本数量:囊括了21项子研究、来自21个国家的3736名患者参与了这些研究。这些患者都患有不同程度的牛皮癣,每个人病变皮肤都占据了整体皮肤面积的10%以上。

经过60周的治疗,其中76.4%-81.8%的患者得到了几乎完全的清除,而对照组只有3%左右。

10年前,我们还没有治愈牛皮癣的有效方法”,Gordon说道:“如今有了这一药物,我们能够在该疾病的治疗方面获得前所未有的成功”。

基于该研究的发现,Gordon认为目前80%的牛皮癣患者在接受ixekizumab治疗之后会获得较大的改善, 其中40%将会完全康复。

Ixekizumab的主要工作原理是阻断免疫系统中促进牛皮癣产生的信号通路,目前该药物已经获得了美国FDA的批准。

不过,该药物也存在一定的副作用,包括轻微的白血球减少症,真菌感染以及IBD等等。

相关结果发表在《The New England Journal of Medicine》杂志上。
