Convalescent Plasma Therapy: A Treatment of Choice for COVID-19 during Current Pandemic

ABSTRACT

The severe acute respiratory syndrome coronavirus 2 which is the source of pandemic coronavirus disease 2019 has engulfed almost whole world. This virus was first reported in Wuhan city (China) in December 2019. Since the discovery of the virus, till today the researchers and scientists have been working to develop new vaccines or therapeutic agents against severe acute respiratory syndrome coronavirus 2. However, thus far no vaccine has emerged that can be approved to treat or prevent coronavirus disease 2019. Due to lack of specific preventative and therapeutic options for the treatment of coronavirus disease 2019, the use of convalescent plasma therapy may be of great benefit in the current situation. Previous use of immune plasma has resulted in successful treatment of hemagglutinin type 1 and neuraminidase type 1 influenza virus, Middle East respiratory syndrome coronavirus and severe acute respiratory syndrome coronavirus 1 epidemics. In the current scenario raised by coronavirus disease 2019, the convalescent plasma therapy has been applied successfully among many patients across various regions. This article presents an up-to-date review of existing literature on recovery through convalescent plasma as a treatment of choice, safety and its efficacy, possibility and its challenges for the treatment of coronavirus disease 2019. © 2022 Indian Pharmaceutical Association.
