Abstract

Introduction: The clinical efficacy of sublingual immunotherapy (SLIT) has already been proven and is known to be high. Its influence on the immunological system of patients suffering from bronchial asthma was also examined. However, it is still unclear how the polysensitisation, coexistence of other atopic disease and asthma treatment step influence the response to treatment with specific immunotherapy. Herein we evaluate the impact of one-year SLIT on selected markers of immunological response depending on different individual and clinical factors of children suffering from atopic asthma and allergic rhinitis.

Material and methods: Twenty-five patients aged 8.1 ± 3.1 years (range 5–15 years), 21 boys and 4 girls, suffering from asthma and allergic rhinitis with polysensitisation to seasonal and non-seasonal allergens, shortlisted for SLIT, were included in the study. Th1 cell and Th2 cell percentages, Bcl-2 expression in T cells, and basophil activation after allergen challenge (house dust mite and/or grass pollen antigen in solution used for skin prick tests) in peripheral blood were measured using flow cytometry. The association between clinical features of asthma and the influence of SLIT on immunological parameters was evaluated with exact Fisher test.

Results: No association between the influence of one-year sublingual immunotherapy on immunological system and patients’ age, polysensitisation, asthma treatment step, or coexistence of any other atopic diseases was observed. However, an increase of the Th1 percentage in children sensitised against more than three allergens was found more often (at the limit of statistical significance) than in the group of children sensitised against three or less allergens.

Conclusions: Based on our results, we cannot point to any subgroup isolated in the study, in which the response of the immunological system to sublingual immunotherapy is more satisfactory than any other. Nevertheless, the increase of Th1 cells may be more specific for polysensitised children.
