JAMA:瑞德西韦似乎对中度新冠肺炎没有明显治疗效果

近期《美国医学会杂志》(JAMA)的一份研究指出,瑞德西韦似乎对中度新冠肺炎患者没有明显治疗效果,与此前对瑞德西韦的报告结果不一致。

近期《美国医学会杂志》(JAMA)的一份研究指出,瑞德西韦似乎对中度新冠肺炎患者没有明显治疗效果,与此前对瑞德西韦的报告结果不一致。

美国国立卫生研究院曾发布一项研究,瑞德西韦使重症新冠肺炎患者康复时间缩短了四天。这种治疗效果仅限于需要接受氧气治疗的患者,非重症患者治疗似乎没有很大区别。

这是一项新的研究,采用随机、开放标签试验,命名为GS-US-540-5774,在美国、欧洲和亚洲的105家医院进行,从2020年3月15日到4月18日对确诊的严重急性呼吸道综合征冠状病毒2(SARS-CoV-2)感染和中度COVID-19肺炎(肺部浸润和氧饱和度>94%)的住院患者进行登记。最终随访日期为2020年5月20日。

患者以1:1:1的比例随机接受10天疗程的瑞德西韦(n = 197),5天疗程的瑞德西韦(n = 199),或标准治疗(n = 200)。瑞德西韦在第1天以200mg静脉注射,然后100mg/d。主要终点是第11天的临床状态,采用7点序数表,范围从死亡(1类)到出院(7类)。使用比例赔率模型计算瑞德西韦治疗组和标准治疗组之间的差异,并以OR表示。OR大于1表示瑞德西韦组与标准治疗组的临床状态分布向7类的差异。

结果发现,在596名随机抽样的患者中,瑞德西韦组与标准治疗组的临床状态分布相似。在596名被随机化的患者中,584名患者开始研究并接受瑞德西韦或继续标准治疗(中位年龄,57[四分位数范围,46-66]岁;227名[39%]女性;56%有血管疾病,42%有高血压,40%有糖尿病),533名(91%)完成试验。5天瑞德西韦组患者的中位治疗时间为5天,10天瑞德西韦组患者为6天。在第11天,5天瑞德西韦组患者的临床状态分布较好的几率在统计学上显著高于接受标准治疗的患者(几率比,1.65;95% CI,1.09-2.48;P = .02)。10天瑞德西韦组和标准治疗组在第11天的临床状态分布没有显著差异(通过Wilcoxon秩和检验,P = 0.18)。到第28天,9名患者死亡:5天瑞德西韦组为2名(1%),10天瑞德西韦组3名(2%),标准治疗组4名(2%)。与标准治疗相比,瑞德西韦治疗的患者中恶心(10% vs 3%)、低钾血症(6% vs 2%)和头痛(5% vs 3%)更为常见。

这项研究表明,在中度COVID-19患者中,随机接受10天疗程瑞德西韦治疗的患者在开始治疗后11天的临床状态与标准治疗相比没有统计学上的显著差异。随机接受5天疗程瑞德西韦治疗的患者与标准治疗相比,临床状态有统计学上的显著差异,但这种差异的临床重要性不确定。

总体而言,在本项研究中发现,瑞德西韦在中度新冠肺炎患者中显示好坏参半的结果。在5天疗程治疗中,它可以帮助患者达到更好的临床状态,但是10天疗程组效果并未超过对照组。

这一结果与此前吉利德赞助的一项研究结果不一致。该研究表明,无论接受5天或是10天瑞德西韦治疗,不需进行机械通气治疗的中度疾病患者得到了相似的临床结果。

目前,瑞德西韦已经获得美国FDA紧急使用授权治疗重症新冠肺炎患者,在欧盟它只批准用于治疗需要氧气治疗的患者。本月早些时候,吉利德提交新药申请适用于所有的住院患者治疗,基于最新研究成果,瑞德西韦的全面治疗计划能否实现,还很难说。

研究作者指出,目前还不知道临床症状改善的7个标准(从出院到死亡)是否具有明确的临床意义,因为它还不像死亡率一样是一个黑白分明的衡量标准。另一份评论也指出,对于患者、临床医生和政府官员来说,很难将简单的优势转化为具有临床意义的具体指标。

吉利德公司临床研究负责人Diana Brainard也对此表示,药物的临床益处很难以确定,除了生存指标外,如何更好地衡量患者的治疗结果是一个新的话题。

还有一点,5天和10天疗程组并不等于实际治疗。只有76%被随机分配到5天疗程的患者完成了治疗;35名患者(18%)在治疗结束前完全康复。在10天组的193名患者中,只有38%完成了整个疗程;98名患者(51%)在治疗10天前出院。治疗天数的中位数是6天。完成10天疗程的一小部分患者可能对研究结果造成了混淆。

根据此前以及本项研究结果,最适合瑞德西韦的患者群,最佳的治疗时间,我们还没有定论。
