The severity of the disease was assessed using standard clinical indices — PASI and BSA. The clinical efficacy was determined by the percentage of PASI reduction 50/75/90/100: good response (PASI ≥ 75) and low efficacy/poor response (PASI ≤ 50). The findings were statistically analyzed and visualized using RStudio and the R programming language. To identify factors associated with treatment efficacy, three analytical approaches were used: multivariate logistic regression, random forest algorithm, and regularized logistic regression (LASSO).</p> <p><bold>RESULTS:</bold><bold> </bold>By<bold> </bold>Week 16, PASI scores ≥ 75 were achieved in 113 patients (72%), insufficient efficacy (PASI ≤ 50) was observed in 43 patients (27%); by Week 26 — in 129 (84%) and 24 (16%), respectively. The highest proportion of patients with insufficient responses was observed in the adalimumab and etanercept groups at Weeks 16 and 26 (46% and 57%; 27% and 25%, respectively). It has been established that the key and most consistent predictor of the efficacy of biologic therapy in patients with moderate-to-severe psoriasis is body mass index: an increase in this indicator is associated with a reduced likelihood of achieving a good clinical response. Arterial hypertension is also associated with lower treatment efficacy, while a higher HDL level can be considered an additional favorable prognostic factor.</p> <p><bold>CONCLUSION:</bold> Consideration of the metabolic and cardiovascular patient characteristics may increase the validity of the choice of biologic therapy in clinical practice.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Несмотря на накопленные данные о значении клинических показателей для прогнозирования эффективности терапии ингибиторами интерлейкинов, полученные результаты противоречивы.</p> <p><bold>Цель.</bold> Определить значимость ряда клинических признаков в качестве предикторов эффективности или неэффективности терапии тяжёлого и среднетяжёлого псориаза генно-инженерными биологическими препаратами.</p> <p><bold>Методы.</bold> В исследование включены 156 пациентов с обыкновенным псориазом (L40.0 по МКБ-10). Степень тяжести заболевания оценивали по стандартизированным клиническим индексам — PASI, BSA. Клиническая эффективность считалась по достижению уровня РАSI 50/75/90/100: хороший ответ — РАSI ≥ 75; недостаточная эффективность/плохой ответ — РАSI ≤ 50. Статистический анализ и визуализация полученных данных проведены с использованием среды R-Studio и языка программирования R. Для выявления факторов, ассоциированных с эффективностью терапии, применяли три аналитических подхода: многомерную логистическую регрессию, алгоритм случайного леса (random forest) и регуляризованную логистическую регрессию (LASSO).</p> <p><bold>Результаты.</bold> К 16-й неделе значений РАSI ≥ 75 были достигнуты у 113 пациентов (72%), недостаточная эффективность (РАSI ≤ 50) наблюдалась у 43 пациентов (27%); к 26-й неделе — у 129 (84%) и 24 (16%) соответственно. Наибольшая доля пациентов с недостаточным ответом наблюдалась в группах терапии адалимумабом и этанерцептом к 16-й и 26-й неделе лечения (46 и 57%; 27 и 25% соответственно). Установлено, что ключевым и наиболее устойчивым предиктором эффективности монотерапии генно-инженерными биологическими препаратами у пациентов со среднетяжёлым и тяжёлым псориазом является индекс массы тела: увеличение показателя ассоциировано со снижением вероятности достижения хорошего клинического ответа. Наличие артериальной гипертензии также связано с меньшей эффективностью лечения, тогда как более высокая концентрация холестерина липопротеинов высокой плотности может рассматриваться как дополнительный благоприятный прогностический фактор.</p> <p><bold>Заключение.</bold> Учёт метаболических и сердечно-сосудистых характеристик пациента может повысить обоснованность выбора генно-инженерных биологических препаратов в клинической практике.</p></trans-abstract><kwd-group xml:lang="en"><kwd>psoriasis</kwd><kwd>clinical predictors</kwd><kwd>biologic therapy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>псориаз</kwd><kwd>клинические предикторы</kwd><kwd>генно-инженерные биологические препараты</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>AlQassimi S, AlBrashdi S, Galadari H, Hashim MJ.
