More than 80% of patients with Covid-19 suffer from vitamin D deficiency and this deficiency is more common in men than in women, according to a study conducted on 216 patients and published in the Journal of Clinical Endocrinology & Metabolism.
After following 216 patients with Covid-19 at Marqués de Valdecilla University Hospital in the city of Santander, the researchers noted that 82.2% of them suffered from a vitamin D deficiency and that the men had lower levels. than women.
In particular, according to this study published in the Journal of Clinical Endocrinology & Metabolism, patients with Covid-19 with low levels of vitamin D also had high serum levels of inflammatory markers such as ferritin and D-dimer (a marker linked to blood clotting problems). blood).
Limitations of the study
No relationship was found between vitamin D levels or deficiencies and disease severity.
The authors acknowledge that the work has some limitations, for example that it was performed in a single hospital center, so the data cannot be generalized to other contexts, people or countries.
The study is therefore observational and the role of vitamin D in the prevention of Covid-19 remains to be clarified.
These studies are “certainly needed” to accurately define the role of supplementation with this vitamin in future waves of SARS-CoV-2 infections, the authors summarize.
Role of Vitamin D
Vitamin D is a hormone produced by the kidneys that controls the calcium concentration in the blood and affects the immune system, explains a press release from the Society for Endocrinology, which brings together more than 18,000 experts from 122 countries.
Its shortage is linked to a variety of health problems, but the scientific community is still investigating why.
Likewise, more and more studies are pointing out the beneficial effect of this vitamin on the immune system, especially as regards protection against infections.
