Question Is convalescent plasma useful in preventing worsening respiratory failure or death in patients with OBJECTIVE To evaluate the efficacy of CP plus standard therapy (ST) vs ST alone in preventing COVID-19 pneumonia? Findings In this randomized clinical trial worsening respiratory failure or death in patients with COVID-19 pneumonia. of 487 patients with COVID-19 DESIGN, SETTING, AND PARTICIPANTS This prospective, open-label, randomized clinical trial pneumonia and a partial pressure of enrolled (1:1 ratio) hospitalized patients with COVID-19 pneumonia to receive CP plus ST or ST alone arterial oxygen–to–fraction of inspired between July 15 and December 8, 2020, at 27 clinical sites in Italy. Hospitalized adults with COVID-19 oxygen (PaO2/FiO2) ratio between 350 pneumonia and a partial pressure of oxygen–to–fraction of inspired oxygen (PaO2/FiO2) ratio between and 200 mm Hg at enrollment, the rate 350 and 200 mm Hg were eligible. of the primary clinical end point (need for mechanical ventilation, defined as INTERVENTIONS Patients in the experimental group received intravenous high-titer CP (ⱖ1:160, by PaO2/FiO2 ratio <150 mm Hg, or death) microneutralization test) plus ST. The volume of infused CP was 200 mL given from 1 to a maximum was not significantly different between of 3 infusions.
