The aim: To study the clinical and spirographic features persistence of the bronchial asthma in schoolchildren against the background of the alternative daily doses of inhaled
corticosteroids to increase the effectiveness of anti-inflammatory therapy for this disease.
Materials and methods: A complete comprehensive clinical-paraclinical examination of 65 schoolchildren with persistent asthma was conducted. According to the average
daily dose of inhaled corticosteroids (ICS) the patients were divided into two clinical groups. The first (I) group consisted of 46 children who received ICS in the regimen of
low-to-medium equipotent doses (253.95±9.98 μg per day), and the second (II) comparison group was formed of 19 patients who controlled the pBA using high doses of ICS
(494.74±5.56 μg per day).
Results: The patients of the І clinical group compared to patients of the ІІ group have a higher risk of the mild bronchial obstructive syndrome during asthma attacks. In assessing
the level of control of persistent bronchial asthma using the CIA-scale, it was found that in II group cases of the controlled course of the disease were observed almost two times
less than in children of the I group of comparison. In conducting spirography in children of comparison groups, it was shown that the ratio of indices of bronchospasm (FEV1/
FVC) was worse in patients receiving high doses of ICS.
Conclusions: So, сharacteristic clinical feature of asthma controlled by high doses of ICS is more severe nature of bronchial obstructive syndrome during the period of exacerbation
(OR=1.9-3.0). In the management of persistent bronchial asthma, the Gensler index which has high specificity (94.4%) and accuracy (92.2%) should be used for disease control
verification.
