Vitamin D is a secosteroid hormone produced by the skin during Summer exposure to UVB rays. Hypovitaminosis D is common in Winter (October to March) at Northern latitudes above 20 degrees North, and from April to September at Southern latitudes beyond 20 degrees below the equator. In the past, coronaviruses and influenza viruses have exhibited very high seasonality, with outbreaks occurring preferentially during the Winter. The Covid-19 pandemic is indeed more severe above Winter latitudes of 20 degrees, while it remains until now less severe in the Southern hemisphere, with a much lower number of deaths. Preclinical research suggests that the SARS-Cov-2 virus enters cells via the angiotensin converting enzyme 2 (ACE2). Coronavirus viral replication downregulates ACE2, thereby dysregulating the renin-angiotensin system (RAS) and leading to a cytokine storm in the host, causing acute respiratory distress syndrome (ARDS). Research also shows that vitamin D plays a role in balancing RAS and in reducing lung damage. On the contrary, chronic hypovitaminosis D induces pulmonary fibrosis through activation of RAS. Similarly, hypovitaminosis D has been strongly associated in the literature with ARDS, as well as with a pejorative vital prognosis in resuscitation but also in geriatric units, and with various comorbidities associated to deaths during SARS-Cov-2 infections. Conversely, vitamin D supplementation has been reported to increase immunity and to reduce inflammatory responses and the risk of acute respiratory tract infections. High-dose oral vitamin D3 supplementation has been shown to decrease short-term mortality in resuscitation patients with severe hypovitaminosis D (17% absolute risk reduction). It is considered safe to take oral vitamin D supplementation at doses up to 10,000 IU/day for short periods, particularly in older adults, i.e. a population that is mostly affected by hypovitaminosis D and who should receive at least 1,500 IU of vitamin D daily to ensure satisfactory vitamin D status. Vitamin D supplementation is mentioned as a potentially interesting treatment for SARS-Cov-2 infection but on a scientific basis with a low level of evidence until now. We hypothesize that high-dose vitamin D supplementation improves the prognosis of older patients diagnosed with COVID-19 compared to a standard dose of vitamin D.

Data processed on September 26, 2020.
An HTML report was created for each of the unique drugs, MeSH, and HPO terms associated with COVID-19 clinical trials. Each report contains a list of either the drug, the MeSH terms, or the HPO terms. All of the terms in a category are displayed on the left-hand side of the report to enable easy navigation, and the reports contain a list of correlated drugs, MeSH, and HPO terms. Further, all reports contain the details of the clinical trials in which the term is referenced. Every clinical trial report shows the mapped HPO and MeSH terms, which are also hyperlinked. Related HPO terms, with their associated genes, protein mutations, and SNPs are also referenced in the report.
