Врачам важно понимать, какие факторы связаны с изменением ОФВ1 у пациентов, не получающих терапию CFTR-модуляторами.</p><p>Целью работы явился поиск факторов, оказывающих влияние на изменения ОФВ1 у пациентов с МВ, не получающих терапию CFTR-модуляторами.</p><sec><title>Материалы и методы</title><p>Материалы и методы. Ретроспективно были проанализированы истории болезни пациентов (n = 225) моложе 18 лет, получавших стационарное лечение в педиатрическом отделении Российской детской клинической больницы – филиала Федерального государственного автономного образовательного учреждения высшего образования «Российский национальный исследовательский медицинский университет имени Н.И.Пирогова» Министерства здравоохранения Российской Федерации, а также пациентов старше 18 лет (n = 181), наблюдаемых специалистами Федерального государственного бюджетного учреждения «Научно-исследовательский институт пульмонологии» Федерального медико-биологического агентства России».</p></sec><sec><title>Результаты</title><p>Результаты. Ключевое влияние на показатель ОФВ1 в детском возрасте оказывает нутритивный статус и характер патогенной микрофлоры нижних дыхательных путей. В группе взрослых пациентов ведущая роль принадлежит таким осложнениям, как МВ-ас социированный сахарный диабет и наличие перенесенного пневмоторакса.</p></sec><sec><title>Заключение</title><p>Заключение. Регулярный контроль над ФВД – неотъемлемая часть ведения пациентов с МВ. В данной работе показана взаимосвязь между параметром ОФВ1 и рядом факторов у пациентов, не получающих патогенетическую терапию.</p></sec></abstract><trans-abstract xml:lang="en"><p>One of the most important predictors of the prognosis of cystic fibrosis (CF) is the pulmonary function test – forced expiratory volume in 1 second (FEV1). It is important for physicians to understand the factors associated with changes in FEV1 in patients not receiving CFTR modulators.</p><p>The aim of this study was to identify factors influencing changes in FEV1 in patients with CF not receiving CFTR modulators.</p><sec><title>Methods</title><p>Methods. Retrospective analysis was conducted using medical records of patients (n = 225) under 18 years who received inpatient treatment in the pediatric department of the Russian Children’s Clinical Hospital, the Branch of the Russian National Research Medical University named after N.I.Pirogov, as well as patients over 18 years (n = 181) who were followed by specialists of the Pulmonology Scientific Research Institute under Federal Medical and Biological Agency of Russian Federation.</p></sec><sec><title>Results</title><p>Results. Nutritional status and the nature of pathogenic microflora of the lower respiratory tract have a key impact on the FEV1 indicator in childhood. In the group of adult patients, the leading role belongs to complications such as CF-associated diabetes mellitus and the presence of pneumothorax.</p></sec><sec><title>Conclusion</title><p>Conclusion. Regular monitoring of external respiratory function is an integral part of patient management in CF. This study demonstrates the relationship between FEV1 and a number of factors in patients not receiving pathogenetic therapy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>муковисцидоз</kwd><kwd>объем форсированного выдоха за 1-ю секунду</kwd><kwd>муковисцидоз-зависимый сахарный диабет</kwd><kwd>микрофлора</kwd><kwd>пневмоторакс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cystic fibrosis</kwd><kwd>forced expiratory volume in 1 second</kwd><kwd>cystic fibrosis-related diabetes mellitus</kwd><kwd>microflora</kwd><kwd>pneumothorax</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">Амелина Е.Л., Каширская Н.Ю., Кондратьева Е.И. и др., ред.
