Since it began affecting the world’s population, COVID-19 has attracted the attention of specialists in the field of medicine.
For this reason, several studies are carried out day after day.
However, this Tuesday (10/27), a scientific research conducted by members of the University of Cantabria and the Marqués de Valdecilla Hospital (in Santander, Spain).
Then, published in the magazine Journal of Clinical Endocrinology & Metabolism brought information.
On the relationship between vitamin D and the disease responsible for this pandemic in which we live.
According to the analysis in question, low levels of vitamin D were more frequent in:
- A group of 216 patients hospitalized with the disease in a hospital in Spain compared to 197 people outside the hospital.
- The researchers found a vitamin D deficiency in 82.2% of hospitalized people, compared to 47.2% in the group used for comparison, called “control”.
Therefore, hospitalized people low in vitamin D:
- They showed a higher rate (26.6%, with 12 days) of hospitalization in the Intensive Care Unit (ICU)
- Compared to people with satisfactory levels of vitamin D (12.8%, with 8 days in hospital).
- Interestingly, in the study, those hospitalized with COVID-19 and with low vitamin D levels were only more likely to have chronic illness as well.
Finally, the authors noted an association between the presence of:
“But it’s not a causation, so I can’t yet say that vitamin D deficiency leads to disease or that increased vitamin D can protect against disease.”
“Vitamin D levels should be interpreted with caution, as the population at risk for severe Sars-CoV-2 (virus) infection is likely the same at risk for vitamin D deficiency,” the article states.
Experts who signed the analysis note that published results indicate that increasing vitamin D may be important for risk groups:
- As older people vulnerable to fractures,
- Osteoporosis and muscle loss,
But they reiterate that the conclusion obtained, therefore, is initially limited to just one hospital, which prevents generalization, at least for now.
Of course, COVID-19 and vitamin D.
This isn’t the first time a relationship has been established between COVID-19 and vitamin D:
- In mid-September, researchers from Boston University School of Medicine, also published by the scientific journal Science One Public Library (PLOS ONE).
They pointed out that vitamin D sufficiency is linked:
- A significant decrease in the level of inflammatory markers within the body
- And higher levels of immune cells in the blood.
In this case, the team collected blood samples from 235 patients admitted to hospitals and diagnosed with COVID-19.
So, from that:
- They measured vitamin D levels,
- Associating them with the severity of the infection,
- Loss of consciousness
- And the difficulty in breathing.
The analysis found that:
- patients over the age of 40 who had sufficient levels of vitamin D were 51% less likely to die from COVID-19.
In addition, the University of Córdoba, Spain, published:
- an RCT-type study (randomized and controlled), with vitamin D administered to patients with COVID-19.
In this study, 76 patients with this condition were evaluated.
Of the total, 50 people received vitamin D along with basic hospital care for coronavirus cases.
The other 26 were part of the control group and received only basic treatment.
The therapy consisted of a combination of hydroxychloroquine and azithromycin.
