Vitamin D is associated with a low COVID-19 death rate

"It is the complications from the misdirected fire from the immune system".

Scientists have established a link between low levels of vitamin D and high numbers of deaths due to coronavirus in about 20 European nations. This needs further study, and I hope our work will stimulate interest in this area.

Vitamin D regulates the response of white blood cells, preventing them from releasing such a large number of inflammatory cytokines.

"We found a significant crude relationship between average vitamin D levels and the number Covid-19 cases, and particularly Covid-19 mortality rates, per head of population across the 20 European countries", Dr Lee Smith of ARU said in the statement.

The condition can severely damage the lungs and lead to respiratory distress syndrome and death in some patients and the team said that this was in fact what was killing Covid patients, not the destruction of the lungs by the virus.

"Whereas there are now no results from randomised controlled trials to conclusively prove that vitamin D beneficially affects Covid-19 outcomes, there is strong circumstantial evidence of associations between vitamin D and the severity of Covid-19 responses, including death".

He added that instead there was a significant correlation with vitamin D deficiency.

High enzyme levels in men aids infection
A new study has found that men's blood has higher levels than women's of a key enzyme used by the new coronavirus to infect cells. Now, their study is one of the top answers when people are researching why men are more vulnerable to COVID-19 compared to women.

Vitamin D is a nutrient that is known for its multiple roles in the optimum functioning of human body.

Led by researchers at Northwestern University in the U.S. state of IL, the study looked at data on the admission, recovery and mortality rates for patients with Covid-19 at hospitals and clinics in countries with a large number of confirmed patients, including China, France, Germany, Italy, Iran, South Korea, Spain, Switzerland, the UK and the United States. According to Backman, vitamin D not only strengthens our immune system but it also prevents our immune system from becoming dangerously over-active.

"Our analysis shows that it might be as high as cutting the mortality rate in half", Backman said.

Backman said this correlation might help explain the many mysteries surrounding COVID-19, such as why children are less likely to die. "It will not prevent a patient from contracting the virus, but it may reduce complications and prevent death in those who are infected". Children, on the other hand, may be less susceptible to severe cases in part because their immune system may be less likely to overreact to the virus and cause complications like a cytokine storm. In some research done earlier, the lack of vitamin D and acute respiratory tract infections was revealed.

The authors of the article have called on the Irish government to change its recommendations for vitamin D supplements given their findings.

Professor Rose Anne Kenny said: "In England, Scotland and Wales, public health bodies have revised recommendations since the Covid-19 outbreak. This might be another key to helping protect vulnerable populations, such as African-American and elderly patients, who have a prevalence of vitamin D deficiency".
