ABSTRACT
BACKGROUND: Clinical studies and meta-analyzes have shown that reduced levels of 25-hydroxyvitamin D in the blood contribute to impaired immunity and stimulate excessive inflammation that adversely affects the health of children: The risk of developing bronchial asthma, obstructive bronchitis, and allergic rhinitis increases. AIM: The main purpose of this review is to summarize the present literature data on the relationship between Vitamin D, VRI, and other infectious diseases with a clinical example. MATERIALS AND METHODS: A comprehensive analysis was carried out under Vitamin D in respiratory viral infection and other diseases. RESULTS: The results of fundamental research allow us to assert that Vitamin D is fundamentally necessary for maintaining the normal physiological functioning of the immune system. CONCLUSION: Clinical studies and meta-analyzes have shown that reduced levels of 25 (OH) E in the blood contribute to impaired immunity and stimulate excessive inflammation, which adversely affects the health of children: The risk of developing bronchial asthma, obstructive bronchitis, and allergic rhinitis increases. © 2021 S.
