[OA] Vitamin D and COVID-19

Vitamin D is a hormone that acts on many genes expressed by immune cells. Evidence linking vitamin D deficiency with COVID-19 severity is circumstantial but considerable—links with ethnicity, obesity, institutionalization; latitude and ultraviolet exposure; increased lung damage in experimental models; associations with COVID-19 severity in hospitalized patients.

Vitamin D deficiency is common but readily preventable by supplementation that is very safe and cheap. A target blood level of at least 50 nmol l−1, as indicated by the US National Academy of Medicine and by the European Food Safety Authority, is supported by evidence. This would require supplementation with 800 IU/day (not 400 IU/day as currently recommended in UK) to bring most people up to target.

Randomized placebo-controlled trials of vitamin D in the community are unlikely to complete until spring 2021—although we note the positive results from Spain of a randomized trial of 25-hydroxyvitamin D3 (25(OH)D3 or calcifediol) in hospitalized patients. We urge UK and other governments to recommend vitamin D supplementation at 800–1000 IU/day for all, making it clear that this is to help optimize immune health and not solely for bone and muscle health.

This should be mandated for prescription in care homes, prisons and other institutions where people are likely to have been indoors for much of the summer. Adults likely to be deficient should consider taking a higher dose, e.g. 4000 IU/day for the first four weeks before reducing to 800 IU–1000 IU/day.

People admitted to the hospital with COVID-19 should have their vitamin D status checked and/or supplemented and consideration should be given to testing high-dose calcifediol in the RECOVERY trial. We feel this should be pursued with great urgency. Vitamin D levels in the UK will be falling from October onwards as we head into winter. There seems nothing to lose and potentially much to gain.

Dr. Steven LaTulippe proclaimed to a crowd of President Trump supporters on Nov. 7 that "COVID-19 is no more" and that, throughout the coronavirus pandemic that has so far killed more than 275,000 people in the US this year, neither he nor the staff at his clinic ever wore a face mask when seeing patients.

"I hate to tell you this. I might scare you, but I and my staff, none of us, once wore a mask in my clinic," LaTulippe told a cheering crowd protesting the presidential election results in Salem, Oregon, where attendees aired unfounded and baseless conspiracies of massive voter fraud. "I want to expose what I call 'corona-mania.'"

On Thursday, the Oregon Medical Board suspended LaTulippe's license and ordered the family practice doctor to "stop practicing medicine until further order of the Board," calling his actions "a serious danger to the public health or safety."

According to the order, not only have LaTulippe and his staff refused to wear masks at the South View Medical Arts clinic in Dallas, Oregon, but also, "urge persons who enter the clinic wearing masks to remove their masks."

"[LaTulippe] regularly tells his patients that masks are ineffective in preventing the spread of COVID-19 and should not be worn," the statement reads, despite ongoing evidence that face coverings reduces the risks of spreading a virus that has so far infected more than 14.4 million people in the US.
