[Peculiarities of joint course of allergic rhinitis and bronchial asthma in population of school-age children].

Purpose of the work was to investigate clinical-allergic peculiarities of allergic rhinitis, together with bronchial asthma in school-age children. There were studied random representative group of children, in total 3000 subjects from 6 to 17. According to the results of epidemiological research in school-age children's population, prevalence of allergic rhinitis was 13,2%. In 19,1% of cases, allergic rhinitis was accompanied with bronchial asthma and in 8% of the patients there was indicated bronchial spasm of physical load (verified as clinically, also through the test with physical load), coughing version of asthma was observed in 4,5% of children. Thus, in children with allergic rhinitis, within the structure of clinical versions (by the criteria of severity) of rare bronchial asthma prevailed (69,8%, among which 65% - intermitting form and 4,8% - persisting form), without statistically significant difference between the boys and girls. Combination of inherited predisposition to allergy with the atopic dermatitis, in the in the anamnesis of children with the increased level of general IgE in the blood serum may be considered as early diagnostic predictor of atopic phenotype as for the allergic rhinitis, also for its combination with the bronchial asthma.
