Objective: to assess the effectiveness of anti-inflammatory therapy in children suffering from non-atopic bronchial asthma (BA) depending on acetylation polmorphism.

Materials and methods. The 1st and 2nd degree comprehensive clinical and immunological examination of 45 children with non-atopic asthma has been held. The genetic marker, namely the acetylation type, on the method of W.M. Proebsting — V.I. Gavrilova, modified by Tymofeeva, was determined. According to the acetylation type two clinical groups were formed: the first group included 22 patients with non-atopic type of disease and slow acetylation phenotype, the second one comprised 23 patients suffering from non-atopic BA with fast acetylation phenotype.

Results. The conducted investigations revealed the distinct controlling effect of inhaled corticosteroids in the patients with slow acetylation type, as evidenced by an increase of relative risk by 57.6% and absolute risk by 45.0% of retention control non-atopic BA phenotype, with a minimum number of patients that need to be treated to achieve at least one positive result (NNT) — 1.7.

Conclusions. The slow acetylation status in patients with non-atopic BA increased the chances of disease control with using inhaled corticosteroids by 4.9–6.9 times.

Key words: asthma, children, acetylation status, anti%inflammatory therapy.
