Хроническая тромбоэмболическая легочная гипертензия (ХТЭЛГ) является одним из наиболее тяжелых осложнений тромбоэмболии легочной артерии (ТЭЛА). Фиброзное ремоделирование сосудов малого круга кровообращения на фоне ХТЭЛГ приводит к необратимому увеличению жесткости сосудистой стенки и снижению эффективности лечения ХТЭЛГ. Участие янус-киназы (JAK) в регуляции процессов воспаления и фиброза в сосудистой стенке и легочной ткани позволяет предположить возможную эффективность ингибиторов JAK 1,2 (иJAK) в лечении ХТЭЛГ. Цель – исследование антифибротического действия иJAK для профилактики и лечения ХТЭЛГ. Материалы и методы. Исследование проводили на крысах-самцах стока Wistar. Моделирование ХТЭЛГ выполняли путем многократной эмболизации сосудистого русла частично биодеградируемыми микросферами из альгината натрия. Через 2 недели после последнего введения микросфер было начато применение иJAK в низких, средних и высоких дозах. Для оцеки эффективности применяемой субстанции были использованы тредмил-тест, эхокардиографическое исследование, катетеризация сердца с манометрией правого желудочка (ПЖ), гистологическое исследование легких. Результаты. Было продемонстрировано значимое снижение толерантности к физической нагрузке во всех точках наблюдения животных, перенесших эмболизацию сосудистого русла, по сравнению со здоровыми животными. Отмечалось значимое повышение среднего давления в ПЖ в группе плацебо (15,5±7,7 мм рт. ст.) и группе применения низких доз иJAK (13,4±6,4 мм рт. ст.), по сравнению со здоровыми животными (9,4±2,2 мм рт. ст.). Индекс гипертрофии сосудистой стенки ветвей легочной артерии был значимо ниже в группе применения средней дозы и JAK, по сравнению с группой плацебо (54,9±19,0 и 68,9±23,1 % соответственно). Заключение. Таким образом, подавление асептического воспаления и опосредованного им фиброза с помощью иJAK приводит к снижению выраженности ремоделирования малого круга кровообращения в экспериментальной модели ХТЭЛГ. Этот подход может быть использован в комплексном лечении и профилактике ХТЭЛГ.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Chronic thromboembolic pulmonary hypertension (CTEPH) is the most common complication of pulmonary thromboembolism (PE). Fibrous remodeling of the pulmonary circulation vessels against the background of CTEPH leads to an irreversible increase of the vessel wall stiffness and the ineffectiveness of CTEPH treatment. The involvement of Janus kinase (JAK) in the regulation of vascular wall and lung tissue inflammation and fibrosis allows for the possible effectiveness of JAK 1,2 inhibitors (iJAK) in the course of CTEPH. Purpose – to study the antifibrotic effect of iJAK for the prevention and treatment of CTEPH. Materials and methods. The study was conducted on male Wistar rats. Modeling of CTEPH was performed by sequential embolization of the vascular bed with partially biodegradable sodium alginate microspheres. 2 weeks after the last administration of the microspheres, low, medium and high doses of iJAK were initiated. To assess the effectiveness of the substance, the following tests were used: treadmill test, echocardiography, cardiac catheterization with right ventricular (RV) manometry, histological examination of the lungs. Results. Animals undergone vascular embolization demonstrated decreased exercise tolerance at all observation points compared to healthy animals. The placebo group, in contrast with the group getting treatment and iJAK, was found to have an increased mean RV pressure compared to healthy animals. There was an increase in mean RV pressure in the placebo group (15.5±7.7 mmHg) and in the low dose and iJAK group (13.4±6.4 mmHg) compared with healthy animals (9.4±2.2 mmHg). Vascular hypertrophy of the pulmonary artery branches was lower in group getting average dosages and iJAK compared with the placebo group (54.9±19.0 and 68.9±23.1 %, respectively). Thus, the suppression by iJAK of aseptic inflammation and following fibrosis leads to the decreasing of severity of pulmonary circulation remodeling in the experimental model of CTEPH. This approach can be used in the comprehensive bypass and prevention of CTEPH.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тромбоэмболия легочной артерии</kwd><kwd>хроническая тромбоэмболическая легочная гипертензия</kwd><kwd>альгинат натрия</kwd><kwd>микросферы</kwd><kwd>экспериментальная модель</kwd><kwd>крыса</kwd><kwd>ХТЭЛГ</kwd><kwd>фиброзное ремоделирование</kwd><kwd>янускиназа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pulmonary embolism</kwd><kwd>chronic thromboembolic pulmonary hypertension</kwd><kwd>sodium alginate</kwd><kwd>microspheres</kwd><kwd>experimental model</kwd><kwd>rat</kwd><kwd>CTEPH</kwd><kwd>fibrous remodeling</kwd><kwd>Janus kinase</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке государственного задания № 122041800020-2</funding-statement><funding-statement xml:lang="en">The study was financially supported by state task No. 122041800020-2.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Grosse SD, Nelson RE, Nyarko KA, Richardson LC, Raskob GE.
