Despite the proven efficacy and safety of biologics in the treatment of psoriasis (Ps), a number of patients experience heterogeneity in response to therapy in both the short-term and long-term perspectives.</p> <p><bold>Aims</bold>. To identify correlations between the blood cytokine levels, clinical severity indices and the effectiveness of the IL-12/IL-23 inhibitor (ustekinumab) therapy.</p> <p><bold>Methods</bold>. The study enrolled 25 patients with psoriasis. The severity of the disease was assessed using PASI, BSA, sPGA. The clinical efficacy of ustekinumab was determined by the percentage of PASI reduction: good response(≥90) moderate response (≥75) and low efficacy (≤50). Blood cytokine levels were determined by multiplex immunological analysis (xMAP) technology. Statistical analysis was performed using RStudio and the R programming language.</p> <p><bold>Results</bold><bold>.</bold> Moderate Ps was diagnosed in 15 patients (60%), severe — in 10 (40%). The baseline levels of IL31, sCD40L and VEGF were respectively 2.3 (<italic>p</italic> = 0.018),2.3 (<italic>p</italic> = 0.010), and 2.0 (<italic>p</italic> = 0.033) times higher in severe Ps. By the 16th week, therapy was effective in 92% of patients and was accompanied by a 3.47 fold decrease in IL-31 (<italic>p</italic> = 0.002) and an increase in ICAM1 and VEGF by 35.8% (<italic>p</italic> = 0.026) and 4.2 times (<italic>p </italic>&lt; 0.001) respectively. A correlation between ∆PASI and IL-12, IL-17F, IL-20, IL-22, IL-31, sCD40L, VEGF was found. Ustekinumab significantly modified cytokine interactions and neutralized their correlation with ∆PASI.</p> <p><bold>Conclusion</bold><bold>.</bold> IL-31, sCD40L and VEGF baseline levels correlate with Ps severity, IL-17F, IL-20 and IL-31 — with ∆PASI, demonstrating their potential use in objectively determining Ps severity and predicting the ustekinumab therapy effectiveness.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Несмотря на подтвержденную эффективность и безопасность генно-инженерных биологических препаратов в лечении псориаза, не у всех пациентов достигаются хорошие результаты — описана гетерогенность ответа на терапию как в кратко-, так и долгосрочной перспективе.</p> <p><bold>Цель исследования. </bold>Выявить взаимосвязи между цитокиновым профилем крови, клиническими индексами тяжести псориаза и эффективностью терапии ингибитором IL-12/IL-23 устекинумабом.</p> <p><bold>Методы. </bold>В исследовании приняло участие 25 пациентов с обыкновенным псориазом (L40.0 по МКБ-10). Степень тяжести заболевания оценивали по стандартизированным клиническим индексам — PASI, BSA, sPGA. Клиническая эффективность устекинумаба считалась по достижению уровня РАSI 50/75/90/100: хороший ответ — РАSI ≥90; удовлетворительный — РАSI 75, плохой — РАSI ≤50. Цитокины крови определялись методом мультиплексного иммунологического анализа с использованием технологии xMAP. Статистический анализ и визуализация полученных данных проведены с использованием RStudio и языка программирования R.</p> <p><bold>Результаты. </bold>Среднетяжелая степень тяжести псориаза диагностирована у 15 (60%) пациентов, тяжелая — у 10 (40%). Выявлены различия в исходных уровнях IL-31, sCD40L, VEGF, которые были соответственно в 2,3 (<italic>р</italic> = 0,018); 2,3 (<italic>р</italic> = 0,010) и 2,0 (<italic>р</italic> = 0,033) раза выше при тяжелом псориазе. К 16-й неделе терапия была эффективной у 92% пациентов и сопровождалась снижением IL-31 в 3,47 раза (<italic>р</italic> = 0,002) и повышением ICAM1 и VEGF соответственно на 35,8% (<italic>р</italic> = 0,026) и в 4,2 раза (<italic>р </italic>&lt; 0,001). Выявлены положительные межцитокиновые взаимодействия средней и высокой силы и корреляция изменения PASI с IL-12, IL-17F, IL-20, IL-22, IL-31, sCD40L, VEGF. Устекинумаб значимо модифицировал межцитокиновые взаимодействия и нивелировал их корреляцию с изменением PASI.</p> <p><bold>Заключение. </bold>Исходные уровни IL-31, sCD40L, VEGF коррелируют с тяжестью псориаза, а IL-17F, IL-20 и IL-31 — с изменением PASI, что демонстрирует возможность их применения в качестве объективизации степени тяжести псориаза, а также в прогнозе эффективности терапии устекинумабом.</p></trans-abstract><kwd-group xml:lang="en"><kwd>psoriasis</kwd><kwd>blood cytokines</kwd><kwd>cytokine network</kwd><kwd>psoriatic arthritis</kwd><kwd>IL-12/IL-23 inhibitor ustekinumab</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>псориаз</kwd><kwd>цитокины крови</kwd><kwd>цитокиновая сеть</kwd><kwd>псориатический артрит</kwd><kwd>ингибитор IL-12/IL-23 устекинумаб</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was carried out within the framework of State Assignment to State Research Center of Dermatovenereology and Cosmetology of the Ministry of Health of Russia (No. 056-00102-22-00).</funding-statement><funding-statement xml:lang="ru">Исследование проведено за счет финансирования по месту работы авторов в рамках государственного задания ФГБУ «ГНЦДК» Минздрава России № 056-00102-22-00.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Кубанов А.А., Богданова Е.В.
