Hospital officials at Hoag Memorial Hospital are calling for patients who have recovered from coronavirus to donate plasma so the antibodies could be used to help current patients recover. Plasma donations helped Ebola patients recover and so Hoag Memorial Hospital Dr. Arell Shapiro, who is in charge of transfusions and lab medicine at the hospital, said he jumped at the chance to join a study on using plasma on ICU patients at Hoag.“We’ve treated 58 patients with over 100 units of convalescent plasma,” Shapiro said. “We don’t yet know the efficacy of how well the plasma has affected the patients’ outcome, but we think it’s having a good effect on the outcome. The problem is we don’t have data from the study analyzed yet.”
