The research goal is to study the performance of INF-а, INF-y and IL-1(3 in children with acute respiratory viral infection (ARVI) depending on etiology, the presence of mixed infection, disease severity, presence of complications, the concentration of thyroid hormones. Material and Methods. Examined 147 patients aged from 1 to 10 years at the outbreak of the ARVI and 15 healthy children. Patients in the midst of acute respiratory infections was conducted to determine levels of IL-1(3, INF-а, INF-y, triiodothyronine (T3) and free thyroxine free (T4) by ELISA using standard test kits JSC "Vector-best" (Koltsovo, Novosibirsk region). Results. It was showed elevated level of INF-y in patients with PC-infection in comparison with the same indicator in healthy children. Set the increased level of INF-а in severe ARVI and the level of INF-y at medium severe form. It was showed increased levels of INF-y in patients with mixed infection. In children with complications, the level of IL-1 (3 was lower almost in 2.4 times, than in children without complications. Among patients with complications, the highest numbers of INF-а were detected in children with pneumonia and INF-y increased in patients with bronchitis. When conducting correlation analysis, the highest rates of INF-а were observed in children with the syndrome of "low T3", and INF-y in children as low T3 and low T4. Conclusion. An increase in the level of INF-y in patients with RS infection was found. Revealed that in children in acute period of SARS levels IL-1 IS, INF-а do not depend on the etiological factor of SARS. These indicators are influenced by the severity of the disease, which in our study was due to the development of mixed infection, the presence and nature of complications. High rates of INF-а and INF-y have significant inverse correlation with the level of T3, which reflects the degree of intoxication in the acute period of infectious diseases.
