The objective of this work was to compare characteristics of clinical condition and immune status of children with repeated respiratory diseases of different clinical and nosological forms after standard treatment and magnetotherapy. It was shown that magnetotherapy produces well-apparent immunocorrective effects in children with the affected upper and lower respiratory tracts including patients with bronchial obstruction syndrome. Positive changes of both cellular and humoral immunity characteristics were documented coupled to the improvement of serum cortisol levels. Results of the study give reason to recommend inclusion of magneotherapy in the combined treatment of children with repeated respiratory diseases.
