Провести количественную оценку показателей невентилируемого объема легких и неравномерности легочной вентиляции и изучить их клиническое значение у пациентов с сочетанием идиопатического легочного фиброза и эмфиземы легких (СЛФЭ).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Были проанализированы материалы историй болезни 56 пациентов с СЛФЭ и 48 пациентов с идиопатическим легочным фиброзом (ИЛФ). Всем пациентам было выполнено комплексное исследование функции внешнего дыхания (ФВД), включающее проведение спирометрии, общей бодиплетизмографии и оценки диффузионной способности легких. Отдельно проанализированы невентилируемый объем (ΔОЕЛ) и индекс неравномерности вентиляции легких (НВЛ).</p></sec><sec><title>Результаты</title><p>Результаты. Показатели механики дыхания в группе пациентов с СЛФЭ были значимо более высокими по сравнению с пациентами с ИЛФ. Отношение объема форсированного выдоха за первую секунду (ОФВ1) к жизненной емкости легких (ЖЕЛ), (медиана – 0,76) и ОФВ1 к форсированной ЖЕЛ, (медиана – 0,78) были более низкими, но в большинстве случаев (89,3%) оставались нормальными. Значения ΔОЕЛ и НВЛ были значимо больше в группе пациентов с СЛФЭ (р &lt; 0,001), при этом выявлялись статистически значимые взаимосвязи этих показателей с параметрами, характеризующими бронхиальную проходимость (ОФВ1/ЖЕЛ (р = 0,001), ОФВ1/ФЖЕЛ (р = 0,003)). При увеличении ΔОЕЛ более 500 мл значительно чаще встречалась легочная гипертензия (отношение шансов – 3,102, р = 0,045), а увеличение НВЛ более 15% статистически чаще выявлялось перед наступлением летального исхода (отношение шансов – 7,800, р &lt; 0,001).</p></sec><sec><title>Заключение</title><p>Заключение. Полученные данные свидетельствуют о важности оценки ΔОЕЛ и НВЛ в комплексной диагностике работы аппарата внешнего дыхания при СЛФЭ. Взаимосвязи их с другими показателями проходимости дыхательных путей, а также частотой развития легочной гипертензии и летальных исходов, могут быть важным звеном в определении объема назначаемой терапии этим пациентам.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To quantify the parameters of unventilated lung volume and pulmonary ventilation heterogeneity and study their clinical significance in patients with a combination of idiopathic pulmonary fibrosis and pulmonary emphysema (CPFE).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The case histories of 56 patients with CPFE and 48 patients with idiopathic pulmonary fibrosis (IPF) were analyzed. The study of respiratory function included the measurement of static lung volumes and capacities, speed indicators and diffusion capacity of the lungs. The unventilated volume (ΔTLC) and the fraction of non-ventilated space (PCF) were also analyzed.</p></sec><sec><title>Results</title><p>Results. The respiratory mechanics parameters in the group of patients with CPFE were significantly higher compared to patients with IPF. The ratio of forced expiration volume in the first second (FEV1) to vital capacity (VC), (median – 0.76) and FEV1 to forced VC (FVC), (median – 0.78) parameters were lower, but in most cases (89.3%) remained normal. The values of ΔTLC and PCF were significantly higher in the group of patients with CPFE (p &lt; 0.001), while statistically significant relationships were found between these parameters and the parameters characterizing bronchial patency (FEV1/VC (p = 0.001), FEV1/FVC (p = 0.003)). With an increase in ΔTLC of more than 500 ml, pulmonary hypertension was significantly more common (OR – 3.102, p = 0.045), and an increase in PCF of more than 15% was statistically more often detected before the onset of death (OR – 7.800, p &lt; 0.001).</p></sec><sec><title>Conclusion</title><p>Conclusion. Our data indicate the importance of assessing ΔTLC and PCF in the complex diagnostics of the external respiratory system in the CPFE. Their relationships with other indices of airway patency, as well as the incidence of pulmonary hypertension and fatal outcomes, may be an important link in determining the volume of therapy prescribed to these patients.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сочетание легочного фиброза и эмфиземы легких</kwd><kwd>диффузионная способность легких</kwd><kwd>невентилируемый объем</kwd><kwd>неравномерность вентиляции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>combined pulmonary fibrosis and emphysema</kwd><kwd>diffusion capacity of the lungs</kwd><kwd>unventilated volume</kwd><kwd>ventilation heterogeneity</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">Cottin V., Selman M., Inoue Y., Wong A.W., Corte T.J., Flaherty K.R., Han M.K., Jacob J., Johannson K.A., Kitaichi M., Lee J.S., Agusti A., Antoniou K.M., Bianchi P., Caro F., Florenzano M., Galvin L., Iwasawa T., Martinez F.J., Morgan R.L., Myers J.L., Nicholson A.G., Occhipinti M., Poletti V., Salisbury M.L., Sin D.D., Sverzellati N., Tonia T., Valenzuela C., Ryerson C.J., Wells A.U.
