埃博拉病毒的新克星:高剂量的法匹拉韦

尽管近年来埃博拉病毒疫情反复爆发,受埃博拉病毒感染的患者并没有得到有效的治疗,以至于疫情通常会导致约50%感染者死亡。近日,一项新的研究显示,高剂量的法匹拉韦显著延长了埃博拉病毒感染的非人类灵长类动物的存活率。

抗病毒药物法匹拉韦(favipiravir)先前已在人体中以较低剂量进行了测试,耐受性良好,但未显示出强烈的抗病毒活性。在目前的研究中,研究人员使用受埃博拉病毒感染的26只非人类灵长类动物,并持续追踪它们21天。13只未接受药物治疗,13只接受药物治疗,在给药组中,法匹拉韦的剂量为每日100150180mg/kg。结果显示,所有未经处理或用100mg/kg的法匹拉韦治疗的动物在感染后10天内死亡。在研究的第21天,用150mg/kg法匹拉韦处理的5只动物中的2只(40%)仍然存活,并且用180mg/kg的法匹拉韦处理的5只动物中的3只(60%)存活至第21天。此外,研究表明该药物以药物浓度依赖性方式抑制病毒复制。

法国研究人员Jeremie Guedj及其同事称,这些结果,以及以前收集的关于非人类灵长类动物和人类的耐受性和药代动力学的数据,支持了高剂量的法匹拉韦对人类干预的评估,特别是对于已经接触埃博拉病毒的病例
