Эндогенные окислительные процессы дыхательных путей можно определять с помощью измерения рН КВВ. С целью оценки уровня рН КВВ были обследованы 153 здоровых добровольцев, из них — 51 курильщик и 615 пациентов с заболеваниями легких (131 — с бронхиальной астмой (БА), 205 — с хронической обструктивной болезнью легких (ХОБЛ), 43 — с бронхоэктазами, 72 — с идиопатическим фиброзирующим альвеолитом (ИФА), 142 — с пневмонией, и 22 — с муковисцидозом). КВВ собирали стандартизованным методом с помощью аппарата ECoScreen ("Erich Jaeger", Германия). Уровень рН КВВ определяли с помощью ф32 рН-метра ("Beckman", США) со стеклянным микроэлектродом. Средний уровень рН КВВ у больных БА составил 6,16 ± 0,52, ХОБЛ — 6,35 ± 0,56, бронхоэктазами — 6,13 ± 0,46, ИФА — 5,98 ± 0,30, пневмонией — 5,96 ± 0,37, муковисцидозом — 6,35 ± 0,23, и был значимо ниже, чем у здоровых людей (6,97 ± 0,31; р &lt; 0,0001). При обострении БА и ХОБЛ уровень рН КВВ был достоверно ниже, чем при ремиссии этих заболеваний. После лечения у больных пневмонией обнаружен достоверный прирост значения рН. При ИФА обнаружена корреляционная связь уровня рН КВВ со степенью фиброзно-воспалительных изменений паренхимы легких при КТВР (r = –0,62; p = 0,01), с общей диффузией легких (r = 0,51; p = 0,01) и с индексом Тиффно (r = 0,68; p = 0,004). Таким образом, рН КВВ является четким маркером активности воспаления в дыхательных путях при патологии органов дыхания. Динамическое определение уровня рН КВВ при заболеваниях легких можно использовать для оценки степени выраженности воспаления и эффективности проводимого противовоспалительного лечения.</p></abstract><trans-abstract xml:lang="en"><p>Investigation of inflammatory markers in the exhaled breath condensate (EBC) is a non-invasive method for evaluation and monitoring of bronchopulmonary inflammation. Endogenous oxidative processes in the airways can be evaluated by pH measurement in the EBC. We examined 153 healthy volunteers (of them, 51 smokers) and 615 patients with lung pathology (of them, 131 asthma (BA) patients, 205 COPD patients, 43 patients with bronchiectasis, 72 patients with idiopathic lung fibrosis (ILF), 142 pneumonia patients, and 42 cystic fibrosis patients). EBC was collected with ECoScreen equipment (Erich Jaeger, Germany) using a standardized method. The EBC pH was measured using the f32 PH-meter (Beckman, USA) with a glass microelectrode. The average ECB pH was 6.16 ± 0.52 in BA, 6.35 ± 0.56 in COPD, 6.13 ± 0.46 in bronchiectasis, 5.98 ± 0.30 in ILF, 5.96 ± 0.37 in pneumonia, and 6.35 ± 0.23 in cystic fibrosis. It was significantly lower than in the healthy volunteers (6.97 ± 0.31, р &lt; 0.0001). In patients with exacerbation of BA and COPD ECB pH was considerably lower compared with those in stable condition. A reliable growth of pH was noted in pneumonia patients after treatment of the disease. There was a correlation between ECB pH and severity of fibrotic and inflammatory disorders of lung tissue according to HRCT (r = –0.62, p = 0.01), lung diffusing capacity (r = 0.51, p = 0.01), Tiffeneau index (r = 0.68, p = 0.004) in ILF. Therefore, the ECB pH is a distinct marker of the airway inflammatory severity in lung pathology. The ECB pH monitoring can assess the inflammatory activity and efficacy of anti-inflammatory therapy in lung diseases.</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">Клемент Р.Ф., Лаврушин А.А., Котегов Ю.М., Тер)Пога) сян П.А.
