В последние годы ведется активный поиск клинико-лабораторных маркеров (фенотипов ревматоидного артрита (РА), способных на этапе инициации терапии метотрексатом (МТ) спрогнозировать его эффективность, позволяя врачам практического звена определиться с тактикой выбора стартового препарата. Цель исследования: установить клинико-лабораторные предикторы разного ответа на метотрексат у больных ревматоидным артритом. Материалы и методы. Исследуемую группу составили 294 пациента с достоверным диагнозом РА. В качестве базисного препарата первой линии все больные получали МТ в дозе от 10 до 25 мг в неделю. Через 6 месяцев, по динамике индекса DAS28 (Disease Activity Score), проведена оценка эффективности лечения и выделены группы «ответчиков» и «неответчиков». Далее выполнена обработка следующих клинико-лабораторных данных: пол, индекс массы тела (ИМТ), статус курения, иммунологические показатели (РФ – ревматоидный фактор, АЦЦП – антитела к циклическому цитруллинированному пептиду), возраст дебюта болезни, активность по индексу DAS28, нарушение жизнедеятельности по опроснику HAQ (Health Assessment Questionnaire), системные проявления и нежелательные явления. Оценка взаимосвязи ответа на МТ с клинико-лабораторными маркерами проводилась с использованием двух методов статистической обработки данных: нелинейного анализа главных компонент (Nonlinear Principal Component Analysis (NLPCA) и сравнения групп с использованием критерия χ2 Пирсона. Результаты. Методом NLPCA выделена 1-ая главная компонента, объясняющая сильную связь терапевтического эффекта МТ с исходными значениями DAS28 и HAQ (нагрузка у всех трех компонентов была более 0,7), т.е. пациенты с высокими индексами DAS и HAQ могут хуже отвечать на лечение. Метод сравнения групп с использованием критерия χ2 Пирсона позволил подтвердить вышеуказанный вывод: у неответчиков в дебюте заболевания DAS28 достоверно был более 5,1, а HAQ в диапазоне 2,1-3,0 (p0,05, 95%CI включает 1. Выводы. Неэффективность МТ достоверно ассоциирована с ранним дебютом РА (до 40 лет), высокой воспалительной активностью болезни, значительным нарушением жизнедеятельности и избыточной массой тела вне зависимости от пола и иммунологических маркеров (РФ и АЦЦП). Курение и системные проявления также оказывают негативное влияние на терапию на уровне вероятности. Развитие любых побочных эффектов в ходе лечения служит сильным предиктором неэффективности МТ. Начало болезни в среднем возрасте (40-60 лет), умеренная и низкая активность по DAS28, незначительные функциональные нарушения – клинические маркеры эффективности МТ. </p></abstract><trans-abstract xml:lang="en"><p>Introduction. In recent years an active search is conducted for clinical and laboratory markers (phenotypes of rheumatoid arthritis (RA), capable of predicting its effectiveness at the initiation of methotrexate (MT) therapy, allowing practitioners to determine the tactics of starting drug selection. Objective: to determine clinical and laboratory predictors of different response to methotrexate in patients with rheumatoid arthritis. Materials and methods. The study group consisted of 294 patients with a reliable diagnosis of RA. All patients received MT in the dosage from 10 to 25 mg per week as a first-line baseline drug. After 6 months, according to the dynamics of DAS28 index (Disease Activity Score), the efficacy of treatment was evaluated and "responders" and "non-responders" groups were distinguished. Then the following clinical and laboratory data were processed: gender, body mass index (BMI), smoking status, immunological parameters (RF - rheumatoid factor, ADCP - antibodies to cyclic citrullinated peptide), age of disease onset, activity on the DAS28 index, impaired vital signs on the HAQ (Health Assessment Questionnaire), systemic manifestations and adverse events. The relationship between methotrexate response and clinical and laboratory markers was assessed using two methods of statistical data processing: Nonlinear Principal Component Analysis (NLPCA) and group comparison using Pearson's χ2 criterion. Results. The NLPCA method highlighted the 1st principal component explaining the strong clinical relationship of MT effectiveness from baseline DAS28 and HAQ values (loadings for all three components were greater than 0.7). That is, patients with high DAS and HAQ indices may respond worse to MT monotherapy. The method of group comparison using Pearson's χ2 criterion allowed to confirm the above conclusion: Nonresponders had DAS28 significantly greater than 5.1 and HAQ in the range of 2.1-3.0 (p0.05, 95%CI included 1. Conclusions. The ineffectiveness of MT is significantly associated with the early onset of RA (before 40 years), high inflammatory activity of the disease, significant impairment of vital functions and excess body weight, regardless of gender and immunological markers (RF and ACCP). Smoking and systemic manifestations also have a negative impact on therapy at the probability level. The development of any side effects during treatment is a strong predictor of MT failure. The onset of the disease in middle age (40-60 years), moderate and low activity according to DAS28, minor functional impairments are clinical markers of the effectiveness of MT.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>метотрексат</kwd><kwd>эффективность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>methotrexate</kwd><kwd>efficacy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Насонов ЕЛ, Каратеев ДЕ, Балабанова РМ.
