Before treatment and three months after the start of methotrexate therapy, all patients underwent videodermatoscopy with dimension of the density and size of dilated skin capillaries, ultrasonography of psoriatic plaques and nail bed of affected nails and measurement of doppler blood flow parameters and concentration of VEGF and En-1 in blood plasma.</p> <p><bold>Results.</bold> A direct correlation was established between the average diameter of dilated skin capillaries (vascular glomeruli), the degree of increased blood flow in the doppler energy study of psoriatic plaques skin area and the plasma concentration of VEGF and En-1 and values of PASI, BSA, sPGA and DLQI indices, as well as the severity of doppler blood flow of the nail bed and NAPSI index (<italic>r</italic> = 0.21–0.73). Under the influence of methotrexate treatment, a decrease in diameter and density of vascular glomeruli (16.2 [12.9; 22.5] versus 25.2 [17.1; 33.7] µm before treatment (<italic>p</italic> = 0.002) and (44.6 [31.6; 53.3] versus 53.5 [34.6; 67.4] before treatment (<italic>p</italic> = 0.04), respectively), the degree of blood flow in area of psoriatic plaques and the concentration of VEGF and En-1 (12.5 [6.7; 26.8] pg/ml versus 19.5 [4.7; 48.1] pg/ml after treatment (<italic>p</italic> = 0.002) and En-1 (168.2 [97; 319] versus 274.5 [146; 439] pg/ml(<italic>p</italic> = 0.003), respectively) was observed.</p> <p><bold>Conclusions.</bold> Studied indicators of angiogenesis can be used as additional criteria for assessing the degree of activity and achieving clinical improvement/remission during systemic therapy in patients with moderate and severe psoriasis.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Оценка выраженности патологического ангиогенеза у больных псориазом может рассматриваться в качестве перспективного направления мониторинга активности болезни и эффективности системной терапии.</p> <p><bold>Цель исследования.</bold> Оценка взаимосвязи показателей ангиогенеза в коже и ногтевом ложе больных псориазом с клиническими особенностями течения заболевания и терапевтическим ответом на применение метотрексата путем комплексного изучения динамики морфометрических данных видеодерматоскопии сосудистого русла кожи, выраженности кровотока в дерме и ногтевом ложе при ультразвуковой энергетической допплерографии, плазменных концентраций сосудистого эндотелиального фактора роста (VEGF) и эндотелина-1 (ET-1).</p> <p><bold>Методы.</bold> В основу работы положен анализ данных обследования 82 больных вульгарным псориазом среднетяжелой и тяжелой степени тяжести в стадии обострения, которым впервые назначался метотрексат в виде подкожных инъекций в дозе 10–15 мг в неделю в комбинации с фолиевой кислотой 5 мг в неделю. До лечения и через три месяца от начала терапии метотрексатом всем больным проводили видеодерматоскопию с изучением плотности и размеров расширенных капилляров кожи, ультрасонографию псориатических бляшек и ногтевого ложа пораженных ногтей с определением допплеровских параметров кровотока и изучали концентрацию VEGF и ET-1 в плазме крови.</p> <p><bold>Результаты.</bold> Была установлена прямая корреляционная связь между средним диаметром расширенных капилляров кожи (сосудистых клубочков), степенью повышения кровотока при допплеровском энергетическом исследовании кожи в области псориатических бляшек и величиной плазменной концентрации VEGF и ET-1, значениями индексов PASI, BSA, sPGA и DLQI, а также степенью выраженности допплеровского кровотока ногтевого ложа и индексом NAPSI (<italic>r</italic> = 0,21–0,73). Под влиянием лечения метотрексатом наблюдалось снижение диаметра и плотности сосудистых клубочков: до лечения 25,2 [17,1; 33,7] мкм, после — 16,2 [12,9; 22,5] (<italic>р</italic> = 0,002) и до лечения 53,5 [34,6; 67,4] мкм, после — 44,6 [31,6; 53,3] (<italic>р</italic> = 0,04) соответственно; степени кровотока в области псориатических бляшек и снижение концентрации VEGF и ET-1: VEGF до лечения 19,5 [4,7; 48,1] пг/мл, после — 12,5 [6,7; 26,8] (<italic>р</italic> = 0,002) и ET-1 до лечения 274,5 [146; 439] пг/мл, после — 168,2 [97; 319] (<italic>р</italic> = 0,003) соответственно.</p> <p><bold>Заключение.</bold> Изучаемые показатели ангиогенеза могут применяться в качестве дополнительных критериев оценки степени активности и достижения клинического улучшения/ремиссии при проведении системной терапии больных псориазом среднетяжелого и тяжелого течения. </p></trans-abstract><kwd-group xml:lang="en"><kwd>psoriasis</kwd><kwd>VEGF</kwd><kwd>angiogenesis</kwd><kwd>endothelin-1</kwd><kwd>dermatoscopy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>псориаз</kwd><kwd>ангиогенез</kwd><kwd>VEGF</kwd><kwd>эндотелин-1</kwd><kwd>дерматоскопия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Кубанов А.А., Карамова А.Э., Артамонова О.Г.
