Well, vitamin D actually reduces the cytokin storm, so I don't really get why his/her doctor advised against it in the first place...

The paper I shared in my previous post cites work showing that Vitamin D promotes other kinds of inflammatory cytokines.
So, yeah. Vitamin D might reduce the likelihood of a cytokine storm, and circumstantial evidence relying on mechanism-of-action suggests that it does -- but this hasn't been demonstrated conclusively.
What is known, however, and which this paper reiterates, is that if you're deficient in Vitamin D, you're more likely to suffer from respiratory tract infections. Take a supplement!
For example :
- Heart failure meta analysis: https://www.ncbi.nlm.nih.gov/pubmed/29348609 - Type 2 diabete meta analysis: https://www.ncbi.nlm.nih.gov/pubmed/29490085 - Type 2 diabete meta analysis: https://www.ncbi.nlm.nih.gov/pubmed/29945132
Hell, we even have preliminary human studies dealing with just that: clinical outcome for patients admitted in intensive care unit, with or without a single mega-dose of vitamin D: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4939707/
Thank you, this is what I was looking for! Great outcome.
The other three papers you cite are also all correlations of Vitamin D with inflammatory factors, not with disease outcomes. I must have missed the study that looks specifically at cytokine storms as a dependent variable. Could you point it out to me?
