The importance of vitamin D adequacy for strengthening the immune system against the SARS-CoV-2 virus, especially in the elderly and those suffering from underlying diseases, comes to highlight another study.
Percentage above it 80% of patients with COVID-19 disease in a Spanish hospital presented vitamin D deficiency, as captured in a new study by his researchers University of Cantabria in Santander, Spain, which is published in Journal of Clinical Endocrinology & Metabolism.
Vitamin D is a hormone produced by the kidneys which controls the concentration of calcium in the blood and affects the immune system. Deficiency has been linked to a number of health problems, although it has not yet been scientifically answered why this hormone affects other systems in the body.
Many studies have already demonstrated beneficial effect of vitamin D. in the immune system, especially with regard to protection against infections.
The signatories of the study emphasize that the measurement of vitamin D levels and the treatment of deficiency should be encouraged., especially in high-risk groups such as elderly, people with comorbidities and those who live in nursing homes.
"Vitamin D treatment should be recommended in patients with COVID-19 with low levels of circulating vitamin D., as this approach can have beneficial results, both in musculoskeletal, as well as in the immune system "notes the co-author of the study José L. Hernández, Ph.D. of the University of Cantabria.
The researchers found that the 80% in total 216 patients with COVID-19 at the Universitario Marqués de Valdecilla hospital showed insufficiency Vitamin D. Men had lower levels vitamin D by women.
Patients with COVID-19 with lower vitamin D levels had, also, increased levels in markers of inflammation in serum.
