We studied clinical efficacy of sublingual immunotherapy in children with combined respiratory forms of pollen allergy before and after three courses of treatment. The levels of G-CSF, GM-CSF, IL-10, IL-12p70, IFNγ, IL-13, IL-17A, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-7, TNFα, IL-8, MCP-1, MIP-1β were measured in nasal secretions. In remission state, the children with combined forms of respiratory allergy to pollen allergens showed local signs of chronic inflammatory process (in the nasal mucosa) associated with disturbed immune response, with increased synthesis of proinflammatory cytokines and decreased production anti-inflammatory cytokines, as well as enhanced reactions aimed for allergen elimination. Following clinical success of sublingual immunotherapy, we have shown a reduction in immunological imbalance, due to decreased activity of the systems modulating severity of inflammation and production of pro-inflammatory cytokines.
