The Effect of Magneto-Laser Therapy on the Phenotype of Basophils in Children With Atopic Asthma

Abstract

In recent years there has been growing evidence to suggest a major role of basophils alongside eosinophils and mast cells in allergic inflammation. The aim of this study was to analyze the dynamics of the basophil phenotypes after the use of magneto-la-ser therapy in children with atopic bronchial asthma. Materials and methods. A total of 66 children with mild persistent atopic bronchial asthma (aged 6 to 18 years old) were examined. Group A included 34 children who received magneto-laser therapy together with basic asthma treatment (low dose of inhaled corticosteroids). Group B included 32 children who received only basic asthma therapy. The level of CD203с + , CD203с + CD63 + , CD203с + IgE + basophils was determined in peripheral blood in the beginning of the study, after 2 weeks and after 3 months. Results. A statistically significant decrease in the absolute levels of CD203с+CD63+ and CD203с + IgE + basophils and in the relative level of CD203с + IgE + among all CD203с + basophils was determined in group A after magneto-laser therapy. The comparison of group A and group B indices revealed a significant difference between the relative level of CD203с + IgE + basophils after 12-15 days from the beginning of the study. This indicator was significantly lower in group A than in group B (p<0.05). The absolute level of CD203с + IgE + basophils was significantly lower in group A in comparison with group B after 82-90 days (p<0.05). Conclusions. Magneto-laser therapy can change the phenotype of basophils in children with atopic bronchial asthma, causing suppression of proallergic pa-rameters. Considering these results there is reason to believe, that it is possible to use this method as an additional immunocorrective treatment in patients with basophilic phenotype of atopic asthma.
