环孢菌素 A 加低类固醇治疗 COVID-19 肺炎
2020年9月4日 更新者:JOSE LUIS GALVEZ-ROMERO、Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado
在 SARS-Cov2 大流行期间,普埃布拉 ISSSTE 地区医院的 COVID-19 肺炎患者使用低剂量皮质类固醇和环孢菌素联合依诺肝素治疗的效用
方法:单中心试点研究包括 2020 年 4 月至 2020 年 5 月在墨西哥普埃布拉住院的 PCR+ SARS-CoV2 患者。
类固醇加 CsA 或类固醇的比较治疗。
轻度、中度或重度肺炎通过临床、实验室检查、计算机断层扫描肺损伤评分和临床改善评分来衡量。
在 28 天评估死亡率。
研究概览
详细说明
这是一项在单一中心(ISSSTE 地区医院,墨西哥普埃布拉)进行的试点研究。 疑似或确诊 COVID-19 的连续患者以非盲法和非随机方式分配,接受类固醇加 CsA(干预组)或仅接受类固醇(该医院的治疗标准,对照组),按照个人临床判断。 主要结果是临床改善到出院或死亡的天数。 次要结果是患者的改善,由以下参数定义:较低的氧气需求(每分钟 2 升或更少),连续三天不发烧,呼吸频率 <22,呼吸机减少 50% 或更多入院时的 C 反应蛋白和住院时间。
根据世卫组织的指导,在 2020 年 4 月 15 日至 2020 年 5 月 31 日期间出现与 COVID-19 肺炎相符的症状的成年患者被邀请参加,所有患者都签署了书面知情同意书。
