Study on the Safety and Efficacy of Convalescent Plasma in Patients With Severe COVID-19 Disease

Convalescent Plasma as a Treatment for Patients With Severe COVID-19 Disease

Currently, there is no specific treatment or vaccine for SARS-CoV-2 available, some drugs are being investigated as treatment, but the effect is unknown. A strategy and other method used before, in coronavirus pandemic (SARS-CoV in 2003 and MERS-CoV in 2012), was the use of immune (convalescent) plasma. Passive administration of antibodies through convalescent plasma transfusion may offer the only short-term strategy available to confer immediate immunity and being a relative immediately resource available for treat COVID-19 disease. This research proposes the passive administration of antibodies through the transfusion of convalescent plasma, in patients with severe COVID-19 disease.

A randomized clinical trial comparing administration convalescent plasma to standard therapy for severe COVID-19 disease. Patients will be randomized 1:1 in a single blind study. The patients with SARS-CoV-2 PCR confirmed infection with pulmonary infiltrates and hypoxemia will be screened and invited to participate. Our primary outcomes will be disease progression and mortality, evaluate of ordinal Scale for Clinical Improvement and. (WHO)
