Presently, the use of convalescent plasma and hyperimmunoglobulin obtained from individuals who have recovered from coronavirus disease 2019 (COVID-19) has proved to potentially provide passive antibody-based immunity, thereby leading to several clinical trials to develop an immune-based COVID-19 treatment. However, the therapeutic efficacy of hyperimmunoglobulin in critically ill patients with COVID-19 remains unknown. On 23 October 2020, we first administered GC5131 in a compassionate-use program to critically ill patients at the Kyungpook National University, Chilgok Hospital, Korea. Since then, five more critically ill patients were treated with GC5131 in this compassionate-use program in our hospital up until 17 December 2020. We retrospectively reviewed the clinical responses of six critically ill patients diagnosed with COVID-19 who received the hyperimmunoglobulin concentrate, GC5131, which was produced by the Green Cross Corporation. After the administration of GC5131, five patients died due to an exacerbation of COVID-19 pneumonia. GC5131 was ineffective when administered to critically ill patients with COVID-19. Nevertheless, we propose that to expect a therapeutic effect from GC5131, it should be administered as early as possible to avoid the excessive inflammatory response phase in patients with severe and advanced COVID-19 infection. This step was difficult to achieve in the real world due to the time required for decision making and the process of the compassionate-use program.

GC5131(超免疫球蛋白)疗法在诊断为 COVID-19 的危重患者中的同情使用:病例系列和文献回顾

目前,使用从 2019 年冠状病毒病 (COVID-19) 康复的个体中获得的恢复期血浆和超免疫球蛋白已被证明有可能提供基于抗体的被动免疫,从而导致多项临床试验以开发基于免疫的 COVID-19治疗。然而,高免疫球蛋白对 COVID-19 危重患者的治疗效果仍然未知。2020 年 10 月 23 日,我们首次在韩国漆谷医院庆北国立大学的危重患者中首次使用 GC5131。从那时起,直到 2020 年 12 月 17 日,在我们医院的这项同情使用计划中,又有 5 名危重患者接受了 GC5131 治疗。我们回顾性地审查了 6 名被诊断为 COVID-19 的危重患者接受了绿十字公司生产的高免疫球蛋白浓缩物 GC5131 的临床反应。在施用 GC5131 后,5 名患者因 COVID-19 肺炎恶化而死亡。GC5131 用于 COVID-19 危重患者时无效。尽管如此,我们建议,为了期待 GC5131 的治疗效果,应尽早给药,以避免严重和晚期 COVID-19 感染患者的过度炎症反应阶段。由于决策所需的时间和同情使用计划的过程,这一步在现实世界中很难实现。由绿十字公司生产。在施用 GC5131 后,5 名患者因 COVID-19 肺炎恶化而死亡。GC5131 用于 COVID-19 危重患者时无效。尽管如此,我们建议,为了期待 GC5131 的治疗效果,应尽早给药,以避免严重和晚期 COVID-19 感染患者的过度炎症反应阶段。由于决策所需的时间和同情使用计划的过程,这一步在现实世界中很难实现。由绿十字公司生产。在施用 GC5131 后,5 名患者因 COVID-19 肺炎恶化而死亡。GC5131 用于 COVID-19 危重患者时无效。尽管如此,我们建议,为了期待 GC5131 的治疗效果,应尽早给药,以避免严重和晚期 COVID-19 感染患者的过度炎症反应阶段。由于决策所需的时间和同情使用计划的过程,这一步在现实世界中很难实现。我们建议,为了期待 GC5131 的治疗效果,应尽早给药,以避免严重和晚期 COVID-19 感染患者的过度炎症反应阶段。由于决策所需的时间和同情使用计划的过程,这一步在现实世界中很难实现。我们建议,为了期待 GC5131 的治疗效果,应尽早给药,以避免严重和晚期 COVID-19 感染患者的过度炎症反应阶段。由于决策所需的时间和同情使用计划的过程,这一步在现实世界中很难实现。
