Researchers at Leumit Health Services’ research institute collaborated with researchers from the Azrieli Faculty of Medicine at Bar Ilan University to check whether there is a link between vitamin levels D In the blood and the chance of being infected with the corona virus.

The researchers located all the insured in Leumit Health Services, who were tested for the corona virus and also performed a vitamin level test. D In the blood – a total of 7,807 people, of whom 782 (10.1%) were found to be positive for the corona virus. The study found that among patients infected with the virus, the average level of the vitamin D Blood levels were significantly lower than those not infected. Patients with vitamin level D Lower than 30 ng / ml were more likely to be infected with the virus compared to patients with normal vitamin D levels D.

“The main finding of our study is the significant association between vitamin level D Low blood pressure and the chance of contracting the corona virus, “says Dr. Yevgeny Marzon, director of the Department of Managed Medicine at Leumit Health Services. Furthermore, an analysis of the data of the group of positive patients for the virus found that among patients with a low level of vitamin D In the blood, there was a higher chance of more serious illness and the need for hospitalization. “According to Dr. Marzon,” age over 50 was another significant risk factor for serious illness. “

Dr. Ilan Green, director of the research institute of Leumit Health Services, notes: “The findings in our study are consistent with results of other studies in the field, but the research conducted at Leumit is the largest and most comprehensive done so far in the world.”

Dr. Milena Frenkel-Morgenstern, head of the Laboratory for Complex Diseases at the Faculty of Medicine at Bar Ilan University, added: “According to our analysis, patients who were positive for the virus were younger than those who were not infected. The levels of infection were between the ages of 25 and 50. “

“We may recognize the first peak around age 25 due to the gathering habits at these young ages,” explains Dr. Frenkel-Morgenstern. “The peak around age 50 may be related to a lifestyle that involves a lot of social connections combined with chronic illness.”

According to the medical literature, vitamin D It is an important component of bone health and its deficiency can lead to diseases such as rickets in children and similar conditions in adults such as osteomyelitis (decrease / impairment of new bone mineralization) and osteoporosis (decrease in bone mass and strength, and tendency to fractures). There are also speculations that the vitamin improves the immune system and helps fight various viral infections. There is scientific evidence for the contribution of the vitamin D To reduce the risk of acute respiratory infections.

Recently, following the outbreak of the corona plague, there has been a wide-ranging debate about the link between the vitamin D For the treatment or prevention of viral disease. In early May, a small study was published from Switzerland, which showed that patients with positive coronary heart disease (27 people in total) had a vitamin level D Lower than in patients with a negative result (a total of 80 subjects), but the difference was not statistically significant.

In another study, data were published that indicated a link between regions in Europe whose inhabitants have low levels of vitamin D And among higher mortality rates from coronary heart disease. However, this study did not directly examine vitamin levels D In the blood among patients who died from corona compared to people who recovered from the disease.

According to Prof. Shlomo Winker, head of the medical division of Leumit Health Services, “It is surprising that chronic conditions, such as dementia, cardiovascular disease and chronic lung disease, which were considered risk factors in previous studies, were not found in our study as a factor increasing the rate of infection. “This finding is related to adherence to the Ministry of Health’s guidelines on social exclusion among chronic patients.”

The research partners believe that it has great clinical significance. However, they emphasize that although this is a large and population-based epidemiological study, it is not a randomized clinical trial that could establish a causal relationship between vitamin administration. D And preventing infection with the corona virus.
