Hypovitaminosis d - a risk factor for obstructive bronchitis recurrences in children

Аннотация

Respiratory pathology, including obstructive bronchitis in young children, remains one of the urgent problems of modem pediatrics. It is known that acute lower respiratory tract infections arc one of the leading causes of child mortality in the world, accounting for about 1.4 million deaths annually in children under 5 years of age. The prevalence of acute obstructive bronchitis, according to various sources, is 25-30%, while in 30-50% of cases the disease has a recurrent course. A family or individual history of allergy and eosinophilia arc well-studied risk factors for recurrent episodes of broncho-obstructive syndrome. At the same time, the role of vitamin D is being actively studied today, as well as the importance of its deficiency in the tendency to recurrent respiratory infections.
