COVID-19 pandemic has been the major threat to the global public health for a year (last of 2019-till date); and unfortunately, there is still as no specific antiviral agent which can be effectively used against this disease curation. Present review focused on the application of the convalescent plasma (CP) therapy as a quick remediation of the disease severity.
While several drugs have been repurposed based on a number of completed clinical trials together with a huge ongoing effort to develop appropriate vaccine against the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the therapeutic approach of the CP therapy appears to be one of the effective methods to rescue the severely affected COVID-19 patients. Such a therapy based on passive immunity evolved from the SARS-CoV-2-infected patients who have fully recovered from COVID-19; and hence these individuals are quite likely to possess high titers of the SARS-CoV-2-neutralizing immunoglobulins (antibodies). However, there are some risks such therapy, and its effectivity also appeared doubtful in some cases. Thus, the current review discussed the issues raised by the administration of such plasma into the SARS-CoV-2-infected individuals.
Application of CP therapy has been conducted since long time; and for the mitigation of COVID-19 severity, such pharmaceutical strategy is also being employed in spite of several risks which actually can be monitored as well as optimized in order to combat the SARS-CoV-2 infection.
新冠疫情在过去一年(2019年末至今)一直是全球公共卫生面临的重大威胁;不幸的是,目前仍没有可有效用于治疗该疾病的特效抗病毒药物。本综述聚焦于恢复期血浆(CP)疗法在快速缓解疾病严重程度方面的应用。
尽管基于多项已完成的临床试验已对多种药物进行了重新利用,并且正在为研发针对严重急性呼吸综合征冠状病毒2(SARS-CoV-2)的合适疫苗付出巨大努力,但CP疗法似乎是挽救重症新冠患者的有效方法之一。这种基于被动免疫的疗法源自已从新冠中完全康复的SARS-CoV-2感染患者;因此这些个体很可能拥有高滴度的SARS-CoV-2中和免疫球蛋白(抗体)。然而,这种疗法存在一些风险,其有效性在某些情况下也受到质疑。因此,本综述讨论了将此类血浆输注给SARS-CoV-2感染个体所引发的问题。
CP疗法的应用由来已久;为减轻新冠的严重程度,尽管存在一些风险,但这种药物策略仍在被采用,实际上这些风险是可以监测和优化的,以对抗SARS-CoV-2感染。
