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 the 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 presented lower levels than women.

Specifically, 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).

Limitations of the study

No relationship between vitamin D levels or deficiencies and disease severity was found.

The authors recognize that the work has certain limitations, for example, that it was performed in a single hospital center, so the data cannot be generalized to other contexts, peoples or countries.

The study is thus observational and the role of vitamin D for the prevention of Covid-19 remains to be elucidated.
These trials are “certainly necessary” to precisely define the role of supplementation with this vitamin in future waves of SARS-CoV-2 infections, summarize the authors.

Role of vitamin D

Vitamin D is a hormone produced by the kidneys that control the concentration of calcium in the blood and affects the immune system, explains a statement from the Society for Endocrinology, which brings together more than 18,000 experts from 122 countries.

Its deficiency is linked to a variety of health issues, but the scientific community is still investigating why.

Likewise, more and more studies emphasize the beneficial effect of this vitamin on the immune system, especially with regard to protection against infections.
