Patients with severe deficiency of Vitamin D are twice as likely to experience severe complications from COVID, including death

Patients with severe deficiency of Vitamin D are twice as likely to experience severe complications from COVID, including death. By Northwestern Now.

The researchers noted that patients from countries with high COVID-19 mortality rates, such as Italy, Spain and the UK, had lower levels of vitamin D compared to patients in countries that were not as severely affected. …

[Vadim Backman, Professor of Biomedical Engineering] and his team were inspired to examine vitamin D levels after noticing unexplained differences in COVID-19 mortality rates from country to country. …

Backman and his team discovered a strong correlation between vitamin D levels and cytokine storm — a hyperinflammatory condition caused by an overactive immune system

“Cytokine storm can severely damage lungs and lead to acute respiratory distress syndrome and death in patients,” [Ali Daneshkhah, a postdoctoral research associate in Backman’s laboratory] said. “This is what seems to kill a majority of COVID-19 patients, not the destruction of the lungs by the virus itself. It is the complications from the misdirected fire from the immune system.”

This is exactly where Backman believes vitamin D plays a major role. Not only does vitamin D enhance our innate immune systems, it also prevents our immune systems from becoming dangerously overactive. This means that having healthy levels of vitamin D could protect patients against severe complications, including death, from COVID-19. …

Backman said this correlation might help explain the many mysteries surrounding COVID-19, such as why children are less likely to die. Children do not yet have a fully developed acquired immune system, which is the immune system’s second line of defense and more likely to overreact.

“Children primarily rely on their innate immune system,” Backman said. “This may explain why their mortality rate is lower.”

COVID deaths largely comes from an overreaction of the acquired immune system, which adults rely on and which is regulated by vitamin D. Children mainly rely on their innate immune system, which does not cause problems with COVID.

So get outside and get some sun, to generate more vitamin D.
