Clinical Nutrition ESPEN; Neves FF, Pott-Junior H et. al.

Jul 26th, 2022 - Several studies have shown conflicting results for the relationship between vitamin D deficiency and COVID-19 outcomes. Here, we aimed to evaluate whether plasma 25(OH)D levels predict mortality in adults admitted with COVID-19, considering potential confounders. We conducted a retrospective cohort study that included 115 adults (age 62.1 ± 17.6 years, 65 males) admitted to a Brazilian public h...

Nature Reviews Immunology; Martineau, A.R. et. al.

Jul 22nd, 2022 - Early in the COVID-19 pandemic, a lack of vaccines and therapies prompted interest in a potential role for vitamin D in reducing risk or severity of disease. This was based on the recognized effects of vitamin D on host responses to other respiratory viruses, and evidence from randomized controlled trials (RCTs) showing the efficacy of vitamin D supplementation for the prevention of other acute...

Jul 22nd, 2022 - Coronavirus disease 2019 (COVID-19) is an infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but the pathogenesis is unclear. Host genetic background is one of the main factors influencing the patients' susceptibility to several viral infectious diseases. This study aimed to investigate the association between host genetic polymorphisms of two genes, ...

Jul 15th, 2022 - Coronavirus disease-2019 (COVID-19) is associated with thromboembolism. Antiphospholipid antibody (APLa) formation is one of the mechanisms. Vitamin D deficiency has been associated with thrombosis in antiphospholipid antibody syndrome. Measure APLa and vitamin D in hospitalized COVID-19 patients with and without thrombosis to evaluate if thromboembolism is associated with concomitant APLa and ...

Journal of Endocrinological Investigation; Coperchini F, Greco A et. al.

Jul 14th, 2022 - A more severe course of COVID-19 was associated with low levels of Vitamin D (VitD). Moreover in vitro data showed that VitD up-regulates the mRNA of the Angiotensin Converting Enzyme 2 (ACE-2), the SARS-COV-2 receptor in different type of cells. ACE-2 is expressed in several type of tissues including thyroid cells, on which its mRNA was shown to be up-regulated by interferon-gamma (IFN-γ). The...
