Patients underwent Doppler ultrasound examination of the skin in psoriatic plaques area and digital dermatoscopy to study the characteristics of vascular angiogenesis loci before treatment and at 1, 3 and 12 months of methotrexate therapy.</p> <p><bold><italic>RESULTS</italic><italic>:</italic></bold> As a result of comparative correlation analysis of dermatoscopy and ultrasonographic Dopplerography indicators dynamics and psoriasis clinical index values during the treatment of patients with methotrexate, moderate and strong correlations were established between the values of the average diameter of the vascular glomerulus and the degree of increased blood flow in psoriatic plaque area after 1 month of methotrexate treatment and the values of PASI at 3, 6 and 12 months from the start of treatment (r=0.54–0.76, <italic>p</italic>=0.002–0.005), as well as between the mean vascular glomerulus diameter values and the degree of skin blood flow increase after 3 months and PASI and BSI indices after 6 and 12 months (r=0.36–0.74, <italic>p</italic>=0.001–0.036). Disappearance of Doppler signals in psoriatic plaques skin and decrease in vascular glomeruli average diameter after 1 month from the start of therapy in 1.76 [1.38; 2.30] and 1.30 [1.38; 2.30] times increase the probability of achieving clinical improvement after three months of methotrexate treatment. The correlation coefficient between the degree of NAPSI reduction after 6 and 12 months of treatment and the dynamics of Doppler blood flow in the nail bed and resistance index of arterial vessels in the nail bed after three months from the start of treatment varied from 0.53 to 0.73.</p> <p><bold><italic>CONCLUSIONS</italic><italic>: </italic></bold>The dynamics of instrumental methods indicators for studying pathological angiogenesis correlates with the probability of achieving clinical improvement in psoriasis symptoms during systemic methotrexate therapy.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Одним из важных патогенетических звеньев псориаза является патологический ангиогенез. В то же время прогностическое значение инструментальных методов в исследовании выраженности ангиогенеза в псориатических бляшках остаётся малоизученным.</p> <p><bold>Цель исследования</bold> ― клиническая оценка взаимосвязи между динамикой показателей ангиогенеза (морфометрические показатели сосудистых клубочков и показатели допплеровского кровотока в коже и ногтевом ложе) и показателями клинической эффективности метотрексата в течение 12 месяцев терапии.</p> <p><bold>Материал и методы.</bold> В основу работы положен анализ клинических данных 82 больных вульгарным псориазом среднетяжёлой и тяжёлой степени тяжести в стадии обострения, которым после первичного осмотра был назначен метотрексат. Пациентам проводили ультразвуковое допплеровское исследование кожи в области псориатических бляшек и цифровую дерматоскопию с изучением характеристик сосудистых локусов ангиогенеза до начала лечения и на 1, 3 и 12-м месяцах терапии метотрексатом.</p> <p><bold>Результаты.</bold> Сравнительный корреляционный анализ динамики показателей дерматоскопии и ультрасонографической допплерографии и индексов, отражающих клиническую симптоматику псориаза, в процессе лечения больных метотрексатом продемонстрировал корреляционные связи средней и сильной степени между значениями среднего диаметра сосудистого клубочка и степенью повышения кровотока в коже в области псориатической бляшки через 1 месяц от начала лечения метотрексатом и значениями индекса PASI через 3, 6 и 12 месяцев от начала лечения (r=0,54–0,76, <italic>p</italic>=0,002–0,005), а также между значениями среднего диаметра сосудистого клубочка и степенью повышения кровотока в коже через 3 месяца и индексами PASI и BSI через 6 и 12 месяцев (r=0,36–0,74, <italic>p</italic>=0,001–0,036). Исчезновение допплеровских сигналов в коже псориатических бляшек и уменьшение среднего диаметра сосудистых клубочков через 1 месяц от начала терапии в 1,76 [1,38; 2,30] и 1,30 [1,38; 2,30] раза повышают вероятность достижения клинического улучшения псориаза через 3 месяца от начала лечения метотрекcатом. Коэффициент корреляционной связи между степенью снижения NAPSI через 6 и 12 месяцев лечения и динамикой показателей допплеровского кровотока в ногтевом ложе и индекса резистивности артериальных сосудов в ногтевом ложе через 3 месяца от начала лечения варьировал от 0,53 до 0,73.</p> <p><bold>Заключение.</bold> Динамика показателей инструментальных методов изучения патологического ангиогенеза коррелирует с вероятностью достижения клинического улучшения симптомов псориаза под влиянием системной терапии метотрексатом.</p></trans-abstract><kwd-group xml:lang="en"><kwd>psoriasis</kwd><kwd>angiogenesis</kwd><kwd>dermatoscopy</kwd><kwd>methotrexate</kwd><kwd>ultrasonography</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>псориаз</kwd><kwd>ангиогенез</kwd><kwd>дерматоскопия</kwd><kwd>метотрексат</kwd><kwd>ультрасонография</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Olisova OY, Anpilogova EM.
