COVID-19 – инфекционное высококонтагиозное заболевание, вызываемое новым коронавирусом SARS-CoV-2. После острой фазы и выписки из стационара у выздоравливающих людей сохраняются респираторные жалобы, изменения функции системы дыхания (ФВД) и показателей компьютерной томографии органов грудной клетки (КТ ОГК).</p></sec><sec><title>Цель</title><p>Цель. Оценить изменения функциональных и количественных КТ ОГК-показателей легких у больных, перенесших коронавирусную пневмонию тяжелого течения.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено поперечное обсервационное исследование: было обследовано 55  пациентов  (из них 28 мужчин в возрасте от 32 до 78 лет) с диагнозом «интерстициальный процесс в легких вследствие перенесенной новой коронавирусной инфекции». Всем больным было выполнено комплексное исследование ФВД (спирометрия, бодиплетизмография, измерение диффузионной способности легких: DLCO) в интервале 24–305 дней после отрицательного результата теста на SARS-CoV-2  и выписки из стационара. КТ ОГК проводили одновременно с функциональным обследованием (±30 дней), рассчитывали показатели: участки «матового стекла», функциональный объем легочной ткани (ФО), объем пораженной ткани (ОП), CovidQ (соотношение ОП/ФО).</p></sec><sec><title>Результаты</title><p>Результаты. Снижение DLCO было выявлено у 28 человек. Рестриктивные нарушения – у 13 человек, обструктивные нарушения – у 2. На момент обследования у всех пациентов сохранялись резидуальные изменения обоих легких различной степени выраженности. Функциональные показатели (ФЖЕЛ, ОЕЛ и DLCO) статистически значимо коррелировали с данными КТ ОГК.</p></sec><sec><title>Выводы</title><p>Выводы. В период выздоровления у пациентов после COVID-19, по данным КТ ОГК, сохраняются структурные изменения легких, по крайней мере, в течение 3 мес. Показатели легочной вентиляции у большинства пациентов нормализуются в течение этого времени, у половины пациентов сохранялось снижение диффузионной способности легких. Благодарности. Исследование выполнено в рамках выполнения государственного задания по теме: «Влияние новой коронавирусной инфекции SARS-CoV-2 на функциональные показатели системы дыхания в период реконвалесценции» (шифр: «Пост-COVID-функциональная диагностика»).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. COVID-19 is a highly contagious infectious disease caused by the novel coronavirus SARS-CoV-2. After the acute phase and discharge from the hospital, convalescent people continue to have respiratory symptoms, changes in pulmonary function (PF) and indicators of chest computed tomography (CT).</p></sec><sec><title>Aim</title><p>Aim. To evaluate changes in PF and quantitative CT data in patients after severe coronavirus pneumonia.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A cross-sectional observational study was conducted: 55 patients (including 28 men, aged 32–78 years) with a diagnosis of “lung interstitial process due to a coronavirus infection” were examined. All patients underwent a study of PF (spirometry, body plethysmography, measurement of the diffusion lung capacity: DLCO) in the interval of 24–305 days after discharge from the  hospital. CT scan of  the chest was performed simultaneously with the  functional examination (±30 days), the parameters were calculated: ground glass areas, functional lung tissue volume (FV), affected tissue volume (AV), CovidQ (AV/FV ratio).</p></sec><sec><title>Results</title><p>Results. A decrease in DLCO was found in 28 patients. Restrictive disorders – in 13 patients, obstructive disorders – in 2 patients. At the time of the CT examination, all patients had residual changes in both lungs of varying severity. Functional parameters (FVC, TLC and DLCO) were statistically significantly correlated with the CT data.</p></sec><sec><title>Conclusion</title><p>Conclusion. During the  recovery period in  patients after COVID-19, lung structural changes, according to CT scans, persist for at least 3 months. Pulmonary ventilation indicators in most patients normalize during this time, half of the patients retained a decrease in diffusion lung capacity. Acknowledgment. The study was carried out as part of the state task on the topic: “The impact of the new coronavirus infection SARS-CoV-2 on the functional parameters of the respiratory system during the convalescence period” (code: “PostCOVID-functional diagnostics”).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>постковидный период</kwd><kwd>функция системы дыхания</kwd><kwd>спирометрия</kwd><kwd>диффузионная способность легких</kwd><kwd>бодиплетизмография</kwd><kwd>компьютерная томография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>post-COVID period</kwd><kwd>lung function</kwd><kwd>spirometry</kwd><kwd>diffusion lung capacity</kwd><kwd>body plethysmography</kwd><kwd>computed tomography</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">Frija-Masson J., Debray M.P., Gilbert M., Lescure F.X., Travert F., Borie R. et al.
