Plasma therapy has shown promising results in a first, a COVID-19 patient receiving care at a private hospital in New Delhi. The 49-year-old became seriously ill and on the night of 14 April, fresh plasma became administered as a therapeutic option along with normal care procedure. Post-therapy, his health changed, and by the fourth day he was released from ventilator support.
Only a small number of trials were performed in COVID-19 patients worldwide, and plasma therapy was found to be successful in these limited trials. Studies have shown that plasma therapy has been effective in Ebola and in other coronavirs infections like MERS and SARS
The purpose of convalescent plasma therapy is to use antibodies from the blood of a recovered COVID-19 patient to treat patients who are critically ill after they become infected with the virus. The theory of therapy is based on the premise that the blood of a patient who has recovered from COVID-19 creates antibodies with the special ability to combat this novel coronavirus.
