Vitamin D reduces mortality in critically ill hospitalized patients


  • Conducted among 200 hospitalized patients with Covid-19, the study presented in ENDO 2021 showed that vitamin D supplementation reduces the risk of severe disease, as well as the risk of death.

Excellent for the immune system and the cardiovascular system, it promotes the intestinal absorption of calcium and its fixation in the bones, and vitamin D is also beneficial against severe forms of Covid-19.

This is highlighted by a new study from the Montefiore Health System and Albert Einstein College of Medicine in New York (USA), which was presented at ENDO 2021, the Endocrine Society’s annual meeting. According to its authors, patients with low vitamin D levels hospitalized due to a severe form of Covid-19 may see a reduced risk of death or the need for respiratory aid. Receive vitamin D supplements At least 1,000 IU per week.

Less risk of respiratory aid

In October 2020, a study was conducted on The Journal of Endocrinology and Metabolism It showed that 82% of the 200 patients were hospitalized in Spain due to Covid-19 They had a vitamin D deficiency. This new work aims to determine whether receiving vitamin D supplementation prior to hospitalization resulted in less severe Covid-19 disease in patients with vitamin D deficiency.

To find out, the researchers followed 124 adult patients with low levels of vitamin D, measured up to 90 days before they entered Covid-19. They compared people who received a supplement of at least 1,000 international units of vitamin D per week with those who did not, to see if this had an effect on the onset of respiratory support or the risk of death.

When analyzing the results, the researchers then found that patients who received vitamin D were less likely to receive life support or death after being admitted to the ICU. However, the results are not that great, the researchers admit, because these risks are for 37.5% of patients who did not take the supplement versus 33.3% of those who took the supplement.

“ Although we have not been able to show a definitive link to severe forms of Covid-19, it is clear that patients with vitamin D deficiency should receive supplements not only for their bone health, but also for better protection against severe forms of Covid-19. , Corinne Levitus, co-author of the work appreciated. We hope this research encourages clinicians to discuss adding these supplements with their vitamin D-deficient patients, as it may reduce their risk of severe disease.

Optimism should be calmed down?

If the conclusions of this study, like the results of previous work, confirm the effectiveness of vitamin D. Against respiratory infectionsThey are not unanimous. Last February, he worked at the University of São Paulo Medical School and Ibirapuera Field Hospital (Brazil), and Posted in GammaOn the contrary, the use of vitamin D to treat hospitalized patients for moderate to severe cases of Covid disease does not provide greater efficacy compared to a placebo.
