Men 'make better coronavirus plasma donors'
Higher antibody levels were also more often found in older patients, Asian patients and those who had been treated in hospital for COVID-19.
Various previous studies have suggested that men are more likely to become seriously ill by the novel coronavirus than women. Now, men who have had contracted COVID-19 and recovered are being urged to donate plasma from their blood to be used in research into treatments for the highly-contagious disease.
As men are more likely to hit severly by coronavirus, they, therefore, produce higher levels of antibodies than women. This means their plasma could be more useful for saving lives. According to NHS Blood and Transplant in the UK, the plasma could be used to treat hospital patients if trials are successful, the BBC reported.
It started requesting blood and plasma from corona survivors in April and, by mid-May, nearly 600 people had donated their plasma. Of the donations from men, 43% had high enough levels of antibodies to be used in trials, compared with just 29% of those from women.
Higher antibody levels were also more often found in older patients, Asian patients and those who had been treated in hospital for COVID-19. "We'd still like to hear from anybody who had coronavirus or the symptoms," Prof David Roberts, associate director for blood donation at NHS Blood and Transplant, said.
"More plasma donors are needed. But we would especially want to hear from men," he said.
WHAT IS PLASMA?
Plasma is a yellowish liquid which is the largest constituent part of your blood -- making up more than half (about 55%) of its overall content and carries red and white blood cells and platelets around the body. After someone is infected with a virus, the plasma contains antibodies used to help fight infection.
This antibody-rich plasma - called convalescent plasma - is formed when someone has recovered from COVID-19, usually 28 days after being ill.
WHAT IS IT IMPORTANT?
This convalescent plasma could be given to COVID-19 patients by transfusion (like blood) to help them fight off the disease and improve their chances of survival.
WHO CAN DONATE CONVALESCENT PLASMA?
Only those who have had coronavirus symptoms and only once they have fully recovered, giving time for antibodies to develop.
But contrary to the studies saying that men more likely to die from COVID-19 than women worldwide, a recent study in India had suggested that females may have a higher relative-risk of COVID-19 mortality in the country.
There has been another study as per which bald men could be at a higher risk of dying from the novel coronavirus. The hormone Androgen, which causes hair loss in men, has been linked to some of the worst cases of COVID-19 in Spanish hospitals.
