Introduction. Acute respiratory viral infections hold a dominant place in the infectious diseases pattern. There are many drugs that can affect separate arms of the immune response.Aim. To analyze the effectiveness of the systemic use of a combined drug containing interferon-α-2b and a complex immunoglobulin preparation in the treatment of respiratory diseases in frequently ill children.Material and methods. We examined 103 children aged 2-12 years. Upon admission, the children were treated with a combined drug containing interferon a-2b and a complex immunoglobulin preparation (CIP) (Kipferon®) rectally. Children in the control group received standard therapy.Results. Children were admitted to the hospital in the first days of the disease (66.02%), mainly in the moderate form of the disease (96.12%). 81.55% had symptoms of intoxication, catarrhal phenomena and respiratory syndrome. Comparing the time from the onset of the disease when prescribing IFN-α-2b to children, their significantly significant differences were established. Introduction in the early stages of the disease contributes to a faster elimination of all symptoms: fever stopped on average (M ± SD) after 1.76 ± 0.33 and 2.05 ± 0.29 days, respectively, from the moment of admission to the hospital, which was on average 2 days less than in the control group. The transition to a productive cough in the main group occurred on average (M ± SD) after 3.25 ± 0.27 days, in the comparative group - after 5.23 ± 0.31, in the control group - after 8.19 ± 0.42 days. In patients of the main and comparative groups, the length of stay in the hospital was significantly shorter - on average (M ± SD) 8.04 ± 0.81 days than in the control group - 10.56 ± 1.42 days. Hematological parameters returned to normal at an earlier time.Discussion. Rectal route of recombinant IFNi-a2b delivery as suppositories is substantiated with regard to etiopathogenesis and immunology.Conclusion. The article presents the outcomes of the clinical use of Kipferon® as part of the combination therapy and prevention of complications of acute respiratory viral infections in children: reduced duration of intoxication, fever, faster improvement of the auscultatory status of the lungs, improvement of immune status indicators.
