The efficacy of vitamin D3 supplementation in coronavirus disease 2019 (COVID-19) remains unclear.To investigate the effect a single high dose on hospital length stay patients with COVID-19.This was multicenter, double-blind, randomized, placebo-controlled trial conducted 2 sites Sao Paulo, Brazil. study included 240 hospitalized COVID-19 who were moderately to severely ill at time enrollment from June 2, 2020, August 27, 2020. final follow-up October 7, 2020.Patients randomly assigned receive oral 200 000 IU (n = 120) or placebo 120).The primary outcome stay, defined as date randomization discharge. Prespecified secondary outcomes mortality during hospitalization; number admitted intensive care unit; required mechanical ventilation and duration ventilation; serum levels 25-hydroxyvitamin D, total calcium, creatinine, C-reactive protein.Of randomized patients, 237 analysis (mean [SD] age, 56.2 [14.4] years; 104 [43.9%] women; mean baseline D level, 20.9 [9.2] ng/mL). Median (interquartile range) not significantly different between (7.0 [4.0-10.0] days) groups [5.0-13.0] (log-rank P .59; unadjusted hazard ratio for discharge, 1.07 [95% CI, 0.82-1.39]; .62). difference group significant in-hospital (7.6% vs 5.1%; difference, 2.5% -4.1% 9.2%]; .43), admission unit (16.0% 21.2%; -5.2% -15.1% 4.7%]; .30), need 14.4%; -6.8% 1.2%]; .09). Mean increased after (44.4 ng/mL 19.8 ng/mL; 24.1 19.5-28.7]; < .001). There no adverse events, but an episode vomiting associated intervention.Among COVID-19, D3, compared placebo, did reduce stay. findings do support use treatment moderate severe COVID-19.ClinicalTrials.gov Identifier: NCT04449718.

Abstract Background Vitamin D has an immunomodulatory role but the effect of therapeutic vitamin supplementation in SARS-CoV-2 infection is not known. Aim Effect high dose, oral cholecalciferol on viral clearance. Design Randomised, placebo-controlled. Participants Asymptomatic or mildly symptomatic RNA positive deficient (25(OH)D<20 ng/ml) individuals. Intervention were randomised to receive daily 60 000 IU (oral nano-liquid droplets) for 7 days with target 25(OH)D>50 ng/ml (intervention group) placebo (control group). Patients requiring invasive ventilation significant comorbidities excluded. 25(OH)D levels assessed at day 7, and was continued those <50 intervention arm. inflammatory markers fibrinogen, D-dimer, procalcitonin (CRP), ferritin measured periodically. Outcome measure Proportion patients negative before day-21 change markers. Results Forty individuals (n=16) control (n=24) group. Baseline serum 8.6 (7.1 13.1) 9.54 (8.1 12.5) (p=0.730), group, respectively. 10 out 16 could achieve by day-7 another two day-14 [day-14 51.7 (48.9 59.5) 15.2 (12.7 19.5) (p<0.001) respectively]. (62.5%) participants group 5 (20.8%) arm (p<0.018) became negative. Fibrinogen significantly decreased (intergroup difference 0.70 ng/ml; P=0.007) unlike other biomarkers. Conclusion Greater proportion D-deficient turned a decrease fibrinogen high-dose supplementation. Trial register number NCT04459247.

Vitamin D deficiency co-exists in patients with COVID-19. At this time, dark skin color, increased age, the presence of pre-existing illnesses and vitamin are features severe COVID disease. Of these, only is modifiable. Through its interactions a multitude cells, may have several ways to reduce risk acute respiratory tract infections COVID-19: reducing survival replication viruses, inflammatory cytokine production, increasing angiotensin-converting enzyme 2 concentrations, maintaining endothelial integrity. Fourteen observational studies offer evidence that serum 25-hydroxyvitamin concentrations inversely correlated incidence or severity The date generally satisfies Hill’s criteria for causality biological system, namely, strength association, consistency, temporality, gradient, plausibility (e.g., mechanisms), coherence, although experimental verification lacking. Thus, seems strong enough people physicians can use recommend supplements prevent treat COVID-19 light their safety wide therapeutic window. In view public health policy, however, results large-scale randomized controlled trials required currently progress.

The principal source of vitamin D in humans is its biosynthesis the skin through a chemical reaction dependent on sun exposure. In lesser amounts, can be obtained from diet, mostly fatty fish, fish liver oil and mushrooms. Individuals with deficiency, defined as serum level 25 hydroxyvitamin < 20 ng/dl, should supplemented. Vitamin deficiency prevalent global problem caused mainly by low exposure to sunlight. main role 1,25 dihydroxyvitamin maintenance calcium phosphorus homeostasis. However, receptors are found most human cells tissues, indicating many extra-skeletal effects vitamin, particularly immune cardiovascular (CV) systems. regulates blood pressure acting endothelial smooth muscle cells. Its has been associated various CV risk factors appears linked higher mortality incidence disease (CVD). Several mechanisms have proposed relating such renin-angiotensin-aldosterone system activation, abnormal nitric oxide regulation, oxidative stress or altered inflammatory pathways. latest randomized controlled trials no benefits supplementation for CVD confirmed. Although more work needed establish protective this setting, according current evidences supplements not recommended prevention.
