Lancet Respir Med:阿奇霉素能否让轻中度COVID-19患者获益?

研究评估了阿奇霉素能否有效降低正在门诊接受治疗的轻至中度COVID-19患者住院或死亡率。

阿奇霉素的抗菌、抗炎和抗病毒特性提示对COVID-19的治疗潜力,对于轻中度COVID-19患者的疗效仍未知。Lancet Respir Med杂志的一项研究评估了阿奇霉素能否有效降低正在门诊接受治疗的轻至中度COVID-19患者住院或死亡率。

研究在英国19家医院进行,采用前瞻性、开放性、随机优势试验。招募18岁以上,经临床诊断、极有可能或确诊的COVID-19感染,症状少于14天,适合进行初步门诊治疗的成年人。患者被随机分配(1:1)接受阿奇霉素(500毫克,每日一次,口服14天)加标准治疗或单独标准治疗。主要结果是随机分组后28天内因任何原因死亡或住院。次要结果是随机分组后28天内因呼吸衰竭住院需要机械通气或因任何原因死亡;根据严重不良事件评估阿奇霉素的安全性和耐受性。

研究从2020年6月3日到2021年1月29日,纳入298名患者。6名患者要求退出研究,最终,对292名患者(阿奇霉素组145名,标准治疗组147名)的主要结果进行了评估。

患者平均年龄45.9岁(SD 14.9),纳入研究前症状中位持续时间为6.02天。阿奇霉素组15例(10%)和标准治疗组17例(12%)研究期间住院或死亡(校正OR=0.91; 95%CI, 0.43-1.92; p = 0.80)。每组有两名患者(1%)需要机械通气或死亡,采用Fisher精确检验对阿奇霉素组和标准治疗组进行比较,结果显示无差异。住院时间无差异(校正HR=0.95; 95%CI, 0.46–1.96, p=0.89)。随访期间,两组均未发生严重不良事件。

研究表明,门诊轻至中度COVID-19患者中,标准治疗加用阿奇霉素并不能降低住院、呼吸衰竭或死亡的风险。研究结果不支持阿奇霉素用于轻至中度COVID-19患者。
