Endocrine Society – According to a new study, over 80 percent of 200 COVID-19 patients in a hospital in Spain have vitamin D deficiency.
Vitamin D is a hormone the kidneys produce that controls blood calcium concentration and impacts the immune system. Vitamin D deficiency has been linked to a variety of health concerns, although research is still underway into why the hormone impacts other systems of the body. Many studies point to the beneficial effect of vitamin D on the immune system, especially regarding protection against infections.
The study was published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism. Co-author José L. Hernández, Ph.D., of the University of Cantabria in Santander, Spain said:
“One approach is to identify and treat vitamin D deficiency, especially in high-risk individuals such as the elderly, patients with comorbidities, and nursing home residents, who are the main target population for the COVID-19,”
“Vitamin D treatment should be recommended in COVID-19 patients with low levels of vitamin D circulating in the blood since this approach might have beneficial effects in both the musculoskeletal and the immune system.”
The researchers found 80 percent of 216 COVID-19 patients at the Hospital Universitario Marqués de Valdecilla had vitamin D deficiency, and men had lower vitamin D levels than women. COVID-19 patients with lower vitamin D levels also had raised serum levels of inflammatory markers such as ferritin and D-dimer.
The manuscript, “Vitamin D Status in Hospitalized Patients With SARS-Cov-2 Infection,” was published online, ahead of print.
