A preliminary analysis of an ongoing study of more than 300 COVID-19 patients treated with convalescent plasma therapy at Houston Methodist suggests the treatment is safe and effective. The results, which appear now in The American Journal of Pathology, represents one of the first peer-reviewed publications in the country assessing efficacy of convalescent plasma.
From March 28, when Houston Methodist became the first academic medical center in the nation to infuse critically ill COVID-19 patients with plasma donated from recovered patients, research physicians have used the treatment on 350 patients. The study tracked severely ill COVID-19 patients admitted to Houston Methodist’s system of eight hospitals from March 28 through July 6.
These latest results from Houston Methodist that now measured medical effectiveness offer valuable scientific evidence that transfusing critically ill COVID-19 patients with high antibody plasma early in their illness – within 72 hours after hospitalization proving most effective – reduced the mortality rate.
