Introduction. Despite new diagnostic methods contributing to an understanding of the etiopathogenesis of acute respiratory tract diseases and a variety of drugs for effective therapy, respiratory tract diseases continue to stand first in the overall morbidity profile in both children and adults. Frequently ill children are most susceptible to diseases, especially at the age of 3 to 6 years old, which accounts for up to 75% of all acute respiratory infection cases and shows no positive response to the medical-preventive activities. The article discusses the relationship between allergic rhinitis and recurrent respiratory diseases.Materials and methods. The possibility and effectiveness of complex treatment of allergic rhinitis in 65 frequently ill children aged 3 to 12 years are considered. The main group consisted of 35 children who were included in the traditional anti-allergic therapy with an isotonic solution of sea salt in an age-related dose for 10 days. The comparison group consisted of 30 children who received only traditional anti-allergic therapy, which was comparable in the compared groups. Patients underwent in-depth clinical and specific allergological examinations, as well as assessment of atopic response parameters of mucosal immunity, including determination of eosinophil levels, side, and Il-4 concentrations in nasal secretions.Results. Thus, the 12-month follow-up control over children with AR showed that the annual frequency of ARIs in the treatment group decreased by 1.4 times and, when averaged, was 5.2 cases, while in the comparison group it was 7.3 cases p < 0.05.Conclusions. In children with recurrent respiratory diseases, suffering from allergic rhinitis, the complex anti-allergic therapy, with the inclusion of elimination and irrigation therapy with a preparation based on isotonic sea salt solution, led to a decrease activity of markers of allergic inflammation in the nasal mucosa, which is confirmed by a decrease in the level of eosinophils, secretory IgE and IL-4 in nasal secretions against the background of a decrease in the frequency of acute respiratory diseases during follow-up for a year.
