Early Outpatient Treatment for Covid-19 with Convalescent Plasma

April 19, 2022

David Sullivan and Johns Hopkins colleagues (NEJM March 30, 2022) conducted a randomized trial of over 1,000 adults of all ages and risk levels and showed that outpatient treatment within 9 days of symptom onset with high antibody titer convalescent plasma reduced hospitalizations by more than 50%. If treatment was provided within 5 days of symptom onset, progression to more severe disease was reduced by 80%. This research highlights the value of early high-dose outpatient treatment with convalescent plasma as the place to start therapies in a new pandemic.
