В проспективное исследование включены 40 пациентов с ТВП. Контрольную группу составили 20 практически здоровых добровольцев. Методом лазерной допплеровской флоуметрии при поступлении и через 14 дней терапии оценивали состояние микроциркуляции в слизистой оболочке главного бронха. Анализировали показатели перфузии (M) и амплитуды вазомоторных колебаний. Данные представлены как M±SD. Сравнение групп проводили с помощью U-критерий Манна–Уитни, корреляцию осуществляли по Спирмену. Значимость определяли при p&lt;0,05.Результаты. У пациентов с ТВП при поступлении выявлено статистически значимое снижение перфузии до 14,5±2,8 пф. ед. (в контрольной группе — 25,1±3,5 пф. ед., p&lt;0,001). Отмечено угнетение амплитуды эндотелиального компонента вазомоций (p&lt;0,01), что свидетельствует об эндотелиальной дисфункции. Через 14 дней лечения показатель перфузии вырос до 21,3±3,2 пф. ед. (p&lt;0,05). Установлена обратная корреляционная связь между исходным уровнем перфузии и концентрацией С-реактивного белка (r= -0,58; p&lt;0,05).Заключение. ТВП характеризуется выраженными нарушениями микроциркуляции в бронхиальном русле, которые коррелируют с активностью системного воспаления. Лазерная допплеровская флоуметрия является информативным методом мониторинга локальных гемодинамических расстройств и оценки эффективности терапии.</p></abstract><trans-abstract xml:lang="en"><p>Objective: To assess the state of the microcirculatory bed in the bronchial mucosa of patients with severe community-acquired pneumonia (SCAP) and its association with systemic inflammation markers.Materials and methods: The prospective study included 40 patients with SCAP. The control group consisted of 20 apparently healthy volunteers. Microcirculation in the main bronchial mucosa was evaluated by laser Doppler flowmetry upon admission and on day 14 of therapy. Perfusion (M) and amplitudes of vasomotor oscillations were analyzed. Data are presented as mean±standard deviation (M±SD). Intergroup comparisons were performed using the Mann–Whitney U test; correlations were assessed using Spearman’s rank correlation coefficient. Statistical significance was set at p&lt;0.05.Results: On admission, SCAP patients exhibited a statistically significant reduction in perfusion to 14.5±2.8 perfusion units (PU), compared to 25.1±3.5 PU in controls (p&lt;0.001). Suppression of the endothelial component of vasomotion amplitude was also observed (p&lt;0.01), indicating endothelial dysfunction. After 14 days of treatment, perfusion increased to 21.3±3.2 PU (p&lt;0.05). An inverse correlation was found between baseline perfusion and C-reactive protein (CRP) concentration (r= -0.58; p&lt;0.05).Conclusion: SCAP is associated with marked disturbances in bronchial microcirculation that correlate with the intensity of systemic inflammation. Laser Doppler flowmetry is an informative tool for monitoring local hemodynamic impairments and evaluating therapeutic efficacy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тяжелая внебольничная пневмония</kwd><kwd>микроциркуляция</kwd><kwd>лазерная допплеровская флоуметрия</kwd><kwd>эндотелиальная дисфункция</kwd><kwd>воспаление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>severe community-acquired pneumonia</kwd><kwd>microcirculation</kwd><kwd>laser Doppler flowmetry</kwd><kwd>endothelial dysfunction</kwd><kwd>inflammation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Metlay J.P., Waterer G.W., Long A.C., et al.
