放弃恢复期血浆用于新冠肺炎的支持性治疗为时过早
一项系统综述和荟萃分析的作者得出结论,恢复期血浆(CP)治疗新冠肺炎的益处有限。在其他系统综述中,只有一项发现了CP的益处。然而,荟萃分析需要一个有重点和有意义的临床问题,并且应该包括旨在检验合理假设的研究。支持药物许可的临床试验应旨在尽可能准确地定义研究药物和靶向疾病。在新冠肺炎的情况下,试验细节(例如,疾病的持续时间、阶段和严重程度,以及抗体含量和CP剂量)非常异质。迄今为止可用的证据表明,在用足够高剂量的特异性抗体治疗COVID-19有患严重疾病风险的患者时,应该强化这一假设。已经证明,这种方法是可行的,并且通过汇编所有可用的异质性试验,即使使用系统综述和荟萃分析的最佳方法,也可能无法弥补具有真正可比设计的进一步试验缺乏独立复制的不足。尽管新冠肺炎大流行似乎正在消退,但鉴于新冠肺炎的死亡人数仍然很高,我们不应忽视寻找有效的预防和治疗方法。单克隆抗体在大流行的早期阶段被发现是有效的;然而,由于严重急性呼吸系统综合征冠状病毒2型的新变种破坏了它们的疗效,目前美国国立卫生研究院的指南不再推荐它们。CP可以提供一系列多克隆抗体,与特定流行的病毒变体具有密切的及时和区域联系。为目标特异性和暂时适应的被动免疫原则获得坚实的科学基础将是非常有价值的,这可能是一种快速灵活的工具,也适用于未来新病原体的爆发。

期刊介绍: This journal is devoted to all areas of transfusion medicine. These include the quality and security of blood products, therapy with blood components and plasma derivatives, transfusion-related questions in transplantation, stem cell manipulation, therapeutic and diagnostic problems of homeostasis, immuno-hematological investigations, and legal aspects of the production of blood products as well as hemotherapy. Both comprehensive reviews and primary publications that detail the newest work in transfusion medicine and hemotherapy promote the international exchange of knowledge within these disciplines. Consistent with this goal, continuing clinical education is also specifically addressed.
