PLoS Pathogens; Mohan M, Cherian JJ et. al.

Sep 18th, 2020 - Coronavirus Disease 2019 (COVID-19) pandemic remains a major public health threat in most countries. The causative severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus can lead to acute respiratory distress syndrome and result in mortality in COVID-19 patients. Vitamin D is an immunomodulator hormone with established effectiveness against various upper respiratory infections. Vita...

Obesity, vitamin D deficiency and old age a serious combination with respect to coronav...
Current Opinion in Clinical Nutrition and Metabolic Care; Biesalski HK

Sep 17th, 2020 - Old age, obesity and vitamin D deficiency are considered as independent risk factors for severe courses of COVID-19. The aim of the review is to discuss common features of these risk factors and the impact of vitamin D. The recently discovered relationship between vitamin D and the infection pathway of the virus via the renin--angiotensin system (RAS) and the adipokines leptin and adiponectin p...

SARS-CoV-2 positivity rates associated with circulating 25-hydroxyvitamin D levels.
PloS One; Kaufman HW, Niles JK et. al.

Sep 17th, 2020 - Until treatment and vaccine for coronavirus disease-2019 (COVID-19) becomes widely available, other methods of reducing infection rates should be explored. This study used a retrospective, observational analysis of deidentified tests performed at a national clinical laboratory to determine if circulating 25-hydroxyvitamin D (25(OH)D) levels are associated with severe acute respiratory disease c...

Sunlight, UV Radiation, Vitamin D, and Skin Cancer: How Much Sunlight Do We Need?
Advances in Experimental Medicine and Biology; Holick MF

Sep 12th, 2020 - Vitamin D is the sunshine vitamin for good reason. During exposure to sunlight, the ultraviolet B photons enter the skin and photolyze 7-dehydrocholesterol to previtamin D3 which in turn is isomerized by the body's temperature to vitamin D3. Most humans have depended on sun for their vitamin D requirement. Skin pigment, sunscreen use, aging, time of day, season, and latitude dramatically affect...

Drug Design, Development and Therapy; Liu G, Hong T et. al.

Sep 9th, 2020 - There is no specific and effective medication for coronavirus disease 2019 (COVID-19), and avaccine is not available in recent months. Here, we hypothesize that a single large dose of vitamin D (Vit D) could be an option for trial in COVID-19. Vit D deficiency or insufficiency is very common in the general population as well as in patients with COVID-19. It has been shown that low Vit D level i...

JAMA Network Open; Meltzer DO, Best TJ et. al.

Sep 3rd, 2020 - Vitamin D treatment has been found to decrease the incidence of viral respiratory tract infection, especially in patients with vitamin D deficiency. Whether vitamin D is associated with coronavirus disease 2019 (COVID-19) incidence is unknown. To examine whether the last vitamin D status before COVID-19 testing is associated with COVID-19 test results. This retrospective cohort study at an urba...

Evidence for possible association of vitamin D status with cytokine storm and unregulat...
Aging Clinical and Experimental Research; Daneshkhah A, Agrawal V et. al.

Sep 2nd, 2020 - We present evidence for a possible role of Vitamin D (VitD) deficiency in unregulated cytokine production and inflammation leading to complications in COVID-19 patients. The time-adjusted case mortality ratio (T-CMR) was estimated as the ratio of deceased patients on day N to the confirmed cases on day N-8. The adaptive average of T-CMR (A-CMR) was calculated as a metric of COVID-19 associated ...

Vitamin D supplementation to prevent COVID-19 in patients with COPD: a research perspec...
Advances in Respiratory Medicine; Chaabouni M, Feki W et. al.

Sep 1st, 2020 - There is increased evidence that the massive release of pro-inflammatory cytokines leading to the cytokine storm syndrome shapes the evolution of COVID-19 and is responsible of the severity of COVID-19 in some patients. A recent review argued that vitamin D deficiency could have increased the COVID-19 outbreak and suggested vitamin D supplementation as a preventive action. In fact, many factors...

Vitamin D status and outcomes for hospitalised older patients with COVID-19.
Postgraduate Medical Journal; Baktash V, Hosack T et. al.

Aug 28th, 2020 - Older adults are more likely to be vitamin D deficient. The aim of the study was to determine whether these patients have worse outcomes with COVID-19. We conducted a prospective cohort study between 1 March and 30 April 2020 to assess the importance of vitamin D deficiency in older patients with COVID-19. The cohort consisted of patients aged ≥65 years presenting with symptoms consistent with ...

Reviews in Medical Virology REFERENCES; Teymoori-Rad M, Marashi SM

Aug 27th, 2020 - Evidence suggests that vitamin D supplementation could potentially be effective either in treatment or prevention of coronavirus disease 2019 (Covid-19). Indeed, several studies and trials have begun to investigate the impact of vitamin D supplementation on patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. In this review, we focus on the potential mechanisms ...

Vitamin D and COVID-19 infection and mortality in UK Biobank.
European Journal of Nutrition; Hastie CE, Pell JP et. al.

Aug 27th, 2020 - Low blood 25-hydroxyvitamin D (25(OH)D) concentration has been proposed as a potential causal factor in COVID-19 risk. We aimed to establish whether baseline serum 25(OH)D concentration was associated with COVID-19 mortality, and inpatient confirmed COVID-19 infection, in UK Biobank participants. UK Biobank recruited 502,624 participants aged 37-73 years between 2006 and 2010. Baseline exposure...
