We had studied functional and metabolic activity of blood lymphocytes in allergic rhinosinusitis (ARS) - atopic ARS and polypous rhinosinusitis (PRS). ARS is characterized by the increased level of CD25+ and HLA-DR+-lymphocytes in peripheral blood, IgA concentration in blood serum and sIgA in nasal secretion. At the same time the deviation of immune response is directed towards Th2-lymphocytes and is accompanied by high content of IL-4 and IL-6 in blood serum and nasal secretion. The activity of metabolic enzymes in blood lymphocytes in ARS is caused by exasperation of plastic processes, intensification of lipoid catabolism and increase of the speed of both anaerobic and aerobic oxidation. There are the following specific features of PRS: high level of CD19+-cells, activation of Thl-lymphocytes and high level of those cytokines, which they produce (IFN-γ and IL-2 in blood serum and nasal secretion). At the same time intensification of aerobic enzymes and lipoid metabolism and decreasing of anaerobic processes and aminoacid metabolism in blood lymphocytes are in the progress.

Objective. To investigate the prevalence and clinical manifestations of FA to fish in children in Tomsk region. Patients and methods. In the screening stage the crosssectional study based on screening questionnaires in random samples of children aged 7-10 years (n=13 010) was performed as a part of EuroPrevall project (EuroRrevall, № FP62006TTCTU5 Proposal 045 879). Those, who reported adverse reactions to food in the screening stage were considered as cases (n=652), children without reported reactions were controls (n=636). The casecontrol stage included the completion of a clinical questionnaire, skinprick test to fish (ALK Abellö, Spain), measurement of serum total and specific IgE to fish, componentresolved diagnostics: Cyp c 1, Gad m 1 (ImmunoCAP, ISAC, Phadia, Sweden). Results. The prevalence of verified FA to fish in children 7-10 years in the Tomsk region amounted to 0,32%; in urban children - 0,32%, in rural children - 0,31% (p=0,9). The main manifestations were skin symptoms, oral allergy syndrome, gastrointestinal symptoms. Anaphylactic shock developed in 15% of children with FA to fish. Conclusion. Fish is one of the main triggers of FA in children in Tomsk region, which leads to severe clinical manifestations , including lifethreatening conditions.

The best way to prevent recurrent respiratory infections in children considers the forming of adequate immune response against pathogenic bacteria. In this article efficacy and safety of bacterial lysate Broncho-Vaxome have been comprehensively reviewed.
