ReviewConvalescent plasma in Covid-19: Possible mechanisms of action.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible of the coronavirus disease 2019 (COVID-19) pandemic. Therapeutic options including antimalarials, antivirals, and vaccines are under study. ⋯ Herein, we discuss the possible mechanisms of action of CP and their repercussion in COVID-19 pathogenesis, including direct neutralization of the virus, control of an overactive immune system (i.e., cytokine storm, Th1/Th17 ratio, complement activation) and immunomodulation of a hypercoagulable state. All these benefits of CP are expected to be better achieved if used in non-critically hospitalized patients, in the hope of reducing morbidity and mortality.

ReviewContinuous hydroxychloroquine or colchicine therapy does not prevent infection with SARS-CoV-2: Insights from a large healthcare database analysis.
Some disease-modifying agents commonly used to treat patients with rheumatic diseases/autoimmune disorders, such as hydroxychloroquine and colchicine, are under investigation as potential therapies for the "coronavirus disease 2019" (COVID-19). However, the role of such agents as prophylactic tools is still not clear. ⋯ These findings raise doubts regarding the protective role of these medications in the battle against SARS-CoV-2 infection.
