重磅!依那西普​治愈了法国COVID-19患者

2020-05-12 mBioMan BioMan

TNF-α抑制剂依那西普(etanercept)治疗后,新冠肺炎症状消失了。

近日,法国研究人员发表在Ann Rheum Dis的研究论文“Recovery from COVID-19 in a patient with spondyloarthritis treated with TNF-alpha inhibitor etanercept”Report一例免疫功能缺陷并患有脊柱关节炎的COVID-19病人,通过TNF-α抑制剂依那西普(etanercept)治疗后,新冠肺炎症状消失了。

目前,新冠病毒(SARS-Cov-2)导致的COVID-19已蔓延至全球,成为了一个主要的全球公共卫生问题。虽然,近几个月发表了数千篇COVID-19相关的Research Paper,但是目前在自身免疫性和风湿病患者中使用免疫调节疗法是否与冠状病毒治疗过程中的疗效更好或更差有关仍然不清楚。该研究报告了一例60岁免疫功能缺陷的患者从冠状病毒中恢复的病例。该患者在出现COVID-19症状第五天,接受了每周皮下注射肿瘤坏死因子-α(TNF-α)抑制剂依那西普50mg和20mg甲氨蝶呤的治疗。在第十天,发热、咳嗽的症状消退。

依那西普是目前全球应用极为广泛的TNF-α抑制剂,已在国外临床应用十余年。是抗风湿病的生物制剂。成人应用依那西普的药动学不受性别、年龄、人种、甚至心肾功能的影响,但不同遗传背景可能会影响其临床疗效。对于RA、JIA、PsA和AS的髋关节损害患者,主张与甲氨蝶呤联合使用。Duret说:在我们的观察中,在病毒感染前使用TNF-α抑制剂与冠状病毒的严重演化无关。

到目前为止,还没有对冠状病毒有效的治疗方法。除抗病毒治疗策略外,应考虑针对炎症级联,特别是在最严重的情况下,急性呼吸窘迫综合征的发展与细胞因子释放综合征(CRS)密切相关。

2004年,E.Tobinick建议使用TNF-α抑制剂治疗非典型肺炎冠状病毒感染。虽然TNF-α抑制剂未能显示出治疗感染性休克的疗效,但目前尚不清楚细胞因子阻断策略是否能有效治疗与COVID-19有关的CRS。

截至2020年4月17日,在登记为冠状病毒(ClinicalTrials.gov)的662项临床试验中,共有40项包括生物疾病-修饰抗风湿药物(b-DMARDS)或从风湿病分支机构衍生而来的靶向合成的DMARDs(TS-DMARDS),其中5项将用于管理与冠状病毒有关的CRS。在生物制品中,白细胞介素(IL)-6受体抑制剂(tocilizumab;sarilumab)和IL-1受体拮抗剂(Anakinra)目前分别在21、8和5项试验中进行着评估。

随着疫情呈指数级蔓延,接触DMARDS和感染SARS-CoV 2的患者将同时扩大。在专门负责报告和监测风湿病患者中发生的冠状病毒的合作努力下,包括“EULAR-COVID-19 database”、“The COVID-19 Global Rheumatology Alliance”以及国家协会支持的数据库,将提供关于DMARDS对冠状病毒结果的影响的合并数据和新证据。
