Low levels of vitamin D in the blood are associated with an increased risk of coronary heart disease – This emerges from a new study by Leumit Health Services and Bar Ilan University. The study, published in recent days in the journal FEBS, examined whether there was a link between the level of vitamin D in the blood and the chance of contracting the corona virus.
The researchers located all the insured in the national health services who had been tested for the corona virus and also performed a vitamin D level test in the blood (a total of 7,807 people), of which 782 (10.1%) were found to be positive for the corona virus. The study found that among patients infected with the coronavirus, the average level of vitamin D was Significantly lower Than those who were not infected. That is, patients with low vitamin levels were more likely to be infected with the virus than patients with normal levels.
“The main finding of the study is the significant link between a fairly low level of vitamin D in the blood and the chance of being infected with the SARS-Cob-2 virus, which causes coronary artery-coon-19 disease,” said Dr. Yevgeny Marzon, director of the National Health Services Department of Medicine. Furthermore, in the data analysis of the group of positive patients for the virus was found That among patients with low levels of vitamin D in the blood there was a higher chance of more serious illness and the need for hospitalization. Age over 50 was another significant risk factor for serious illness. “Dr. Ilan Green, director of the National Institutes of Health Research Institute, added that” the findings in our study are consistent with results from other studies in the field, but the study conducted at Leumit is the largest and most comprehensive. “.
“According to our analysis, the positive patients for Covid-19 were younger than those who were not infected. The peak of infection was between the ages of 25 and 50,” said Dr. Milena Frenkel-Morgenstern, head of the Complex Diseases Laboratory at Bar Ilan University’s Faculty of Medicine. The first peak around the age of 25 we identify due to the customs of gathering at these young ages. The peak around the age of 50 may be related to the lifestyle, which involves a lot of social connections combined with chronic diseases. ”
The research partners, Dr. Dmitry Taborovsky and Dr. Alessandro Gurochovsky from Dr. Frenkel-Morgenstern’s laboratory, think that the study is of great clinical significance. However, it should be noted that although it is a large and population-based epidemiological study, it is not a clinical trial. Randomization which can establish a causal link between the administration of vitamin D and the prevention of infection with the corona virus.
Vitamin D is known to be important for bone health and its deficiency can lead to diseases such as rickets in children and similar conditions in adults such as osteomyelitis (decreased / impaired bone mineralization) and osteoporosis (decreased bone mass and strength). There are also speculations that the vitamin improves the immune system and helps fight various viral infections, and there is scientific evidence for its contribution to reducing the risk of acute respiratory infections.
