Background & aim: As on date, no specific treatment is available for devastating COVID-19 (SARS-CoV-2) infection. This pandemic viral infection has affected over 200 countries within a very short time and created a calamitous situation across the globe. As per WHO guidelines, the treatment is mainly symptomatic and supportive. This clinical protocol has not proven sufficient to save the lives of COVID-19 patients suffering from diabetes or having underlying liver diseases; hence there is utmost need to tackle this situation by other means such as Convalescent Plasma (CP) therapy.

Methods: A comprehensive literature survey was carriedout using Elsevier, PubMed, Taylor & Francis, Springer, Nature and Google search engines.

Results: The patients suffering from diabetes or liver dysfunction or any other underlying diseases are at greatest risk of SARS-CoV-2 infection. From the study, it is proved that plasma collected from the recovered patients of viral infection has considerable potential to treat the viral disease without the occurrence of adverse effects.

Conclusion: The CP therapy can be a possible life saving alternative to treat critical COVID-19 patients having diabetes or underlying liver dysfunction. Hence, randomised clinical trials are recommended at the earliest to save the lives of infected individuals of COVID-19.

Schematic mechanism of neutralizing antibodies. Neutralizing antibodies binds with Receptor bonding domain (RBD) of the SARS-CoV-2 Spike protein and inhibits the binding of RBD to ACE2 receptor as shown in the figure. The protruding portion (blue colour) highlights the antibody epitope.
