Convalescent plasma transfusion has shown promise in treating severe COVID-19 infection, according to the first trial completed in the USA. The results come as the first patient in a UK trial dedicated to COVID-19 is treated with the therapy.
The US study was carried out at the Houston Methodist Hospital in Texas. 19 out of 25 patients with severe or life-threatening COVID-19 showed improvements after treatment with convalescent plasma, with no significant side-effects.
The researchers say their results, published in the American Journal of Pathology, demonstrate the safety of convalescent plasma as a treatment.
The doctors say that the improvement in symptoms following convalescent plasma transfusion is similar to that seen in previously published studies of the anti-viral drug remdesivir. However, they acknowledge that a controlled trial is needed to definitively prove its effectiveness.
Researcher Professor James Musser said: “While physician scientists around the world scrambled to test new drugs and treatments against the COVID-19 virus, convalescent serum therapy emerged as potentially one of the most promising strategies.
“With no proven treatments or cures for COVID-19 patients, now was the time in our history to move ahead rapidly.”
Meanwhile in the UK, a child has become first patient in a trial dedicated to COVID-19 to be treated with convalescent plasma.
The treatment, as part of the RECOVERY trial, took place at the Royal Manchester Children’s Hospital. The therapy was carried out by Professor Robert Wynn, a consultant paediatric haematologist who leads the hospital’s paediatric bone marrow transplant programme.
Trial leader Professor Richard Haynes, from University of Oxford, said: “Plasma from patients who have recovered from COVID-19 may help to speed up clearance of the virus from those who are currently suffering from the disease and improve their chances of recovery – but we can’t be certain unless we compare it to no additional treatment beyond the usual standard of care received by all patients.”
