Research progress on clinical application of convalescent plasma from COVID-19 patients.

ABSTRACT

COVID-19 is an acute respiratory infectious disease caused by 2019-nCoV, which has become a major global public health event and a serious threat to human health. So far, specific antiviral drugs, safe and effective vaccines for 2019-nCoV are still under development, so there is an urgent need to find alternative strategies for the treatment of COVID-19. Convalescent plasma(CP) contains high titer neutralizing antibodies from patients recovering from infectious diseases, which has been used in the treatment of major infectious diseases such as severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), and achieved satisfactory clinical results. Therefore, CP from COVID-19 patient is a meaningful choice for the treatment of severe or life-threatening COVID-19 patients, but its potential risks need to be studied. This review focuses on the clinical mechanism, collection points, clinical application and potential benefits and risks of clinical treatment of CP from COVID-19 patients, which will provide reference for the clinical application of CP from COVID-19 patients.Copyright © 2021 Chinese Medical Association
