However, studies on clinically measurable indicators of endothelial dysfunction and their changes during systemic therapy in psoriasis are limited and inconsistent.</p> <p><bold>AIM:</bold> Сomparative assessment of the clinical effect of the IL-17 inhibitor Netakimab and Methotrexate on the values of laboratory markers of endothelial dysfunction in patients with psoriasis in comparison with the dynamics of clinical efficacy indicators over 6 months of therapy.</p> <p><bold>MATERIALS AND METHODS:</bold> The study observed 66 PsA patients initially prescribed Methotrexate (Group 1: 30 patients) or Netakimab (Group 2: 36 patients). Group 1 received Methotrexate 15 mg weekly with Folic acid, while Group 2 received Netakimab 120 mg subcutaneously at weeks 0, 1, 2, then every 4 weeks. Clinical data were analyzed before, 3 months, and 6 months after treatment. Plasma levels of VEGF, endothelin-1 (En-1), and nitric oxide (NO) were measured before treatment and after 3 months.</p> <p><bold>RESULTS:</bold> In psoriasis patients, plasma levels of endothelial dysfunction markers were higher than in the control group: VEGF (19.8 [4.5; 49.4] pg/ml vs. 5.2 [0.5; 9.8] pg/ml, p=0.004), En-1 (286.4 [154; 439] pg/ml vs. 96.5 [32; 188] pg/ml, p=0.002), and NO (4.3 [2.1; 12.5] pg/ml vs. 2.2 [0.2; 5.0] pg/ml, p=0.02). By the third month of therapy, VEGF, En-1, and NO levels decreased, with more significant reductions in Group 2: VEGF decreased by 10.2 [8.4; 13.7] vs. 7.0 [5.6; 11.7] (p=0.043) and En-1 by 184.6 [167; 202] vs. 112.7 [97; 136] (p=0.008) in Group 1. Group 2 also showed a more pronounced decrease in PASI and NAPSI scores at 3 and 6 months.</p> <p><bold>CONCLUSION:</bold> The work demonstrated the ability of the IL-17 inhibitor netakimab to reduce initially elevated values of laboratory markers of endothelial dysfunction.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование</bold><bold>.</bold> Эндотелиальная дисфункция является одним из механизмов, лежащих в основе атеросклеротического поражения сосудистой стенки, и ассоциируется с повышенным риском развития сердечно-сосудистой патологии у больных вульгарным псориазом. В то же время исследования, посвящённые изучению клинически определяемых показателей эндотелиальной дисфункции и их динамики при системной терапии пациентов с псориазом, немногочисленны и противоречивы.</p> <p>Цель исследования ― сравнительный анализ воздействия ингибитора ИЛ-17 нетакимаба и метотрексата на содержание лабораторных маркеров эндотелиальной дисфункции (плазменная концентрация фактора роста эндотелия сосудов, эндотелина-1 и оксида азота) у пациентов с псориазом в сопоставлении с динамикой клинических показателей на протяжении 6 месяцев лечения.</p> <p><bold>Материалы и методы.</bold> В основу исследования положены данные динамического наблюдения за 66 больными псориазом, которым впервые назначались метотрексат (в дозе 15 мг в неделю подкожно в сочетании с приёмом фолиевой кислоты по 5 мг в неделю внутрь; подгруппа 1; <italic>n</italic>=30) или нетакимаб (в дозе 120 мг подкожно по следующей схеме: на 0, 1 и 2-й неделях, затем 1 раз в 4 недели; подгруппа 2; <italic>n</italic>=36). Оценка клинической динамики проводилась до начала терапии, а также через 3 и 6 месяцев лечения. Всем пациентам проведено исследование содержания плазменных концентраций факторов роста эндотелия сосудов, эндотелина-1 и оксида азота как до начала лечения, так и по истечении третьего месяца терапии. Контрольную группу составили 20 практически здоровых добровольцев.</p> <p><bold>Результаты.</bold> У пациентов с псориазом по сравнению с контрольной группой зарегистрирована повышенная концентрация маркеров эндотелиальной дисфункции, однако к концу третьего месяца терапии отмечалось снижение их содержания в плазме крови. Различия в снижении этих показателей между началом лечения и третьим месяцем наблюдения более выражены в подгруппе пациентов, получавших нетакимаб. Анализ клинической динамики лечения показал, что у пациентов подгруппы 2 был зафиксирован более значительный прогресс по снижению индексов PASI (распространённость и тяжесть псориаза) и NAPSI (оценка тяжести поражения ногтей при псориазе) через 3 и 6 месяцев по сравнению с пациентами группы 1.</p> <p><bold>Заключение.</bold> В работе продемонстрирована способность ингибитора ИЛ-17 нетакимаба к снижению исходно повышенных значений лабораторных маркеров эндотелиальной дисфункции.</p></trans-abstract><kwd-group xml:lang="en"><kwd>psoriasis</kwd><kwd>endothelial dysfunction</kwd><kwd>methotrexate</kwd><kwd>netakimab</kwd><kwd>vascular endothelial growth factor</kwd><kwd>endothelin-1</kwd><kwd>nitric oxide</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>псориаз</kwd><kwd>эндотелиальная дисфункция</kwd><kwd>метотрексат</kwd><kwd>нетакимаб</kwd><kwd>фактор роста эндотелия сосудов</kwd><kwd>эндотелин-1</kwd><kwd>оксид азота</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">BIOCAD</institution></institution-wrap><institution-wrap><institution xml:lang="en">BIOCAD</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Lockshin B, Balagula Y, Merola JF.
