COVID-19 Pandemic and the Convalescent Plasma Therapy: Possible Benefits and Risks.

purpose of reviewCOVID-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. RECENT

findingsWhile 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. SUMMARY: 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.
