恢复期血浆疗法治疗重症新冠COVID-19感染患者:临床研究中显示出治疗潜力

2020-04-07 MedSci原创 MedSci原创

在10名34-78岁重症新型冠状病毒COVID-19感染患者中应用恢复期血浆(CP)疗法的一项前期试验表明,CP治疗对于严重的COVID-19感染患者可能是一种安全且有希望的治疗选择。

在10名34-78岁重症新型冠状病毒COVID-19感染患者中应用恢复期血浆(CP)疗法的一项前期试验表明,CP治疗对于严重的COVID-19感染患者可能是一种安全且有希望的治疗选择。

CP疗法是使用COVID-19感染后康复患者捐赠的血浆。如果恢复患者刚刚达到恢复期,他们的血浆中往往含有针对其所接触的所有病原体的高水平中和抗体,因此当CP被输注到另一位患者时,会立即产生免疫反应。对于免疫缺陷、无法独自产生有效免疫应答反应的感染患者,则特别需要这种类型的疗法。

来自中国的研究小组为10例重度COVID-19患者输注了200ml含有高水平抗COVID-19抗体的CP。研究人员表示,输液三天后,发烧、咳嗽、呼吸急促和胸痛等临床症状明显改善。患者的淋巴细胞计数增加、肝功能改善、炎症减少。研究人员还指出,CP输注后患者的中和抗体水平升高且保持较高水平。

根据该团队的说法,输血的7天之内,在胸部CT扫描中观察到了不同程度的肺部病变重减轻,并且在CP输注后未观察到严重的不良反应。
