Clinical and immunological aspects of bronchoobstructive syndrome in children

Respiratory diseases occupy a leading place in the structure of morbidity in young children. In the acute period, these diseases are very often complicated by bronchoobstructive syndrome, with both infectious etiology and allergic nature. Up to 30% of young children had obstructive bronchitis at least once, and bronchial asthma, the clinical equivalent of which is BOS, is registered in almost 10% of the entire child population. At the present stage, the concept of "bronchial obstructive syndrome" is collective, it can accompany various nosological forms of respiratory pathology, including a symptom complex of specifically outlined clinical manifestations of bronchial patency disorders, which are based on narrowing or occlusion of the respiratory tract.
