Although the novel SARS-CoV-2 virus (COVD-19) is classified as an acute respiratory infection, emerging data show that morbidity and mortality are driven by disseminated intravascular coagulopathy. Untreated CAC leads to microangiopathic thromboses, causing multiple systems organ failure and consuming enormous healthcare resources. Identifying strategies to prevent CAC are therefore crucial to reducing COVID-19 hospitalization rates. The pathogenesis of CAC is unknown, but there are major overlaps between severe COVID-19 and vitamin D insufficiency (VDI). We hypothesize that VDI is a major underlying contributor to CAC. Preliminary data from severe COVID-19 patients in New Orleans support this hypothesis. The purpose of the proposed multi-center, prospective, randomized controlled trial is to test the hypothesis that low-risk, early treatment with aspirin and vitamin D in COVID-19 can mitigate the prothrombotic state and reduce hospitalization rates.

The 2019 novel coronavirus disease (COVID-2019) pandemic is an enormous health issue of worldwide scale. Prevention and/or treatment with a widely-available and already-licensed product such as vitamin D (cholecalciferol) could have a large impact on healthcare worldwide. Given ethnic variation in vitamin D production, this could help to address the discrepancies in how people of different ethnicities are affected by COVID-19. There are currently no published studies analysing either individual-level evidence on the effect of vitamin D status on COVID-19 outcomes, or any prospective studies planning on following-up patients with reference to vitamin D and COVID-19 infection. The study will have 2 arms. Arm 1 will recruit patients hospitalised with COVID-19. Vitamin D levels will be measured in these patients and compared with outcome measures of COVID-19 severity. In Arm 2, patients will be recruited prospectively from local general practices (GPs) with measurement of vitamin D levels at enrolment. They will be followed up after 6 months to determine whether baseline vitamin D levels correspond with developing COVID-19. Data will be collected from a mixture of patient medical records, electronic patient records, laboratory data and from patients themselves. Data in Arm 1 will be analysed with a combination of linear and logistic regression, as appropriate, and with adjustment for covariates. Data in Arm 2 will be analysed as a case-control study, with adjustment for covariates. The primary objectives are to determine whether vitamin D levels affect outcomes in COVID-19 infection and whether vitamin D deficiency is associated with increased risk.

This study is intended to address whether oral daily vitamin D supplementation reduces infection with SARS-CoV-2 in healthy young adults. The primary aim of the study is to demonstrate a reduction in 'silent' seroconversion rates, consistent with asymptomatic transmission of SARS-CoV-2, in a young healthy adult population following 24 weeks of taking oral vitamin D supplemented at a dose of 1000 I.U. daily, versus matching placebo. The secondary aims of this study are to explore: 1. Any effect on symptomatic illness. 2. The background 'point' prevalence and subsequent rate of increase in seropositivity for SARS-CoV-2 in healthy young adults. 3. The individual reductions in seropositivity to SARS-CoV-2 over time, and changes in seropositivity in a defined young adult population over time. 4. Where salivary Immunoglobulin A (IgA) may be used to provide an alternative/ complementary serological method 5. The effect (if any) of vitamin D supplementation on seroconversion rates stratified by: i) level of baseline vitamin D 'deficiency/ insufficiency/ sufficiency' status; ii) extent of BMI-defined normal/overweight/obesity cut-offs and iii) gender.

The purpose of this study is to evaluate how useful vitamin D supplementation is in reducing the severity of COVID-19 symptoms and the body's inflammatory and infection-fighting response to COVID-19. Individuals ≥50 years of age and older who are tested for COVID-19 and negative will be randomized (like flipping a coin) to either daily high dose vitamin D supplementation (6000 IU vitamin D3/day) vs. standard of care. Those individuals ≥50 years of age or older who test positive for COVID-19 at baseline will be randomized to bolus vitamin D (20,000 IU/day for 3 days) followed by high dose (6000 IU vitamin D/day) vs. standard of care for 12 months. All participants will receive a multivitamin containing vitamin D.

The world is currently facing a pandemic with the coronavirus (SARS-CoV-2) which leads to the disease of COVID-19. Risk factors for a poor outcome of COVID-19 have so far been identified as older age and co-morbidity including chronic respiratory conditions such as chronic obstructive pulmonary disease (COPD) and current smoking status. Previous studies found, that vitamin D deficiency is more prevalent among patients with these risk factors. There are observational studies reporting independent associations between low serum concentrations of 25-hydroxyvitamin D (the major circulating vitamin D metabolite) and susceptibility to acute respiratory tract infection. Vitamin D substitution in patients with COVID-19 who show a vitamin D deficiency should therefore be investigated for efficacy and safety. The study is designed as a randomized, placebo-controlled, double blind study. The objective of the study is to test the hypothesis that patients with vitamin D deficiency suffering from COVID-19 treated under standardized conditions in hospital will recover faster when additionally treated with a single high dose of vitamin D compared to standard treatment only.

It is known that vitamin D has been found to decrease incidence of viral respiratory infections, as well as have effects on multiple cytokines involved in immunomodulation and the bradykinin/renin-angiotensin system. Recently, data was released showing a correlation between baseline vitamin D deficiency status and increased risk of contracting COVID-19. Separate analysis shows that many of the deleterious effects of COVID-19 may be due to the bradykinin/RAS system, and that vitamin D is one plausible treatment option to modulate these effects. Studies are currently ongoing to determine if vitamin D supplementation of those hospitalized with COVID-19 has a beneficial effect on patient outcomes. Healthcare resources have been strained during the pandemic in areas of heavy caseload. It is possible that those with concurrent vitamin D deficiency and COVID positivity have an increased need for escalation of care. A small study has been conducted in this area, but was limited by small number of subjects.
