2月6日,世界卫生组织新型冠状病毒(2019-nCoV)临床管理专家组J Kenneth Baillie等在Lancet发表评论指出,临床证据不支持应用糖皮质激素来治疗新冠病毒所致肺损伤,甚至还可能有害。

文章指出,对于急性肺损伤和急性呼吸窘迫综合征,部分原因是由免疫反应所致,而应用激素不仅会抑制肺部炎症,也会抑制免疫反应,抑制病原体的清除。

作者汇总了激素治疗不同呼吸道病毒感染的临床结果(表1)。



作者指出,当前尚无临床证据表明应用激素治疗SARS-CoV、MERS-CoV、流感病毒以及呼吸道合胞病毒感染可有净获益。

不仅如此,这些观察性数据反而提示,应用激素会增加流感病毒感染的死亡率和继发感染率,迟滞SARS-CoV和MERS-CoV的清除能力,以及增加合并症发生风险。

最后作者强调,目前没有理由认为应用激素治疗新冠病毒肺炎可获益,不支持临床用其治疗新冠病毒肺炎感染所致的肺损伤及休克。

近日国家卫健委发布《新型冠状病毒感染的肺炎的诊疗方案(试行第五版)》虽然指出,可根据患者呼吸困难程度、胸部影像学进展情况,酌情短期内(3~5 d)使用糖皮质激素,建议剂量不超过相当于甲泼尼龙1~2 mg/(kg·d),但也提醒应当注意较大剂量糖皮质激素由于免疫抑制作用,会延缓对冠状病毒的清除。
