Под наблюдением находилось 15 больных атопической БА средней тяжести течения, которые в течение 2 нед получали сальбутамол в режиме "по требованию", а затем в течение 12 нед получали будесонид (пульмикорт турбухалер в дозе 400 мкг/сут). Концентрацию Н2O2 в КВВ изучали спектрофотометрическим методом ("Gallati&amp;Pracht”, 1985). Бронхиальную проходимость (ОФВ1) изучали методом спирометрии. Для оценки гиперреактивности бронхов (ПД20) использовали бронхопровокационный тест с гистамином.Уровень Н2O2 в процессе лечения сальбутамолом (0,19±0,03 мкМ) существенно не изменялся по сравнению с исходным (0,19±0,04 мкМ), а при назначении будесонида достоверно снижался (0,038±0,005). Изменение Н2O2 происходило параллельно с улучшением клинического состояния больных, увеличением ОФВ1 и снижением ПД20.Таким образом, β2-агонисты не влияют, а ИГКС снижают концентрацию Н2O2 в КВВ у больных БА, что, вероятно, отражает их различное влияние на активность воспалительного процесса. Это подтверждает возможность использования Н2O2 в качестве маркера воспаления в дыхательных путях у пациентов с астмой.</p></abstract><trans-abstract xml:lang="en"><p>Exhaled hydrogen peroxide is a marker of airway inflammation. However, its utility for monitoring of asth­ma is still uncertain. The aim of this study was to assess the effect of short-acting β2-agonists and inhaled steroids on the hydrogen peroxide (H202) concentration in expired breath condensate in asthmatic patients. Fifteen patients with moderate atopic asthma were treated with salbutamol as required for 2 weeks followed 12-week treatment with budesonide (Pulmicort Turbuhaler, 400 meg daily). The exhaled H202 concentration as measured using a colorimetric assay (Gallati&amp;Pracht, 1985). FEV1 was assessed using dry spirometer. Airway hyperresponsiveness was considered as a provocative concentration of inhaled histamine causing the 20%-fall in FEV1 (PD20).The H202 baseline level in the asthmatic patients (0.19±0.03 μ‎M) was elevated compared to healthy sub­jects (0.028±0.003, p&lt;0.001). The exhaled H202 concentration did not change during the treatment with salbutamol but it was diminished by Pulmicort Turbuhaler. This was associated with significant improvement in clinical symptom score, FEV1 and PD20 in asthma patients.We conclude that the short-acting β2-agonists do not influence the H202 concentration in the exhaled air condensate of the asthma patients but the inhaled steroids decrease it. This may reflect different anti-inflam­matory activities of these medications.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Емельянов A.B., Щербак И.Г., Абулимити А. и др.
