В исследование были включены 60 больных РА (44 женщины и 16 мужчин старше 18 лет), соответствовавших критериям Американской коллегии ревматологов и Европейской антиревматической лиги (ACR/EULAR) 2010 г. и получавших МТ ≥20 мг/нед подкожно в течение ≥12 нед. Больные были разделены на две сопоставимые по возрасту, полу, приему алкоголя, количеству курильщиков, индексу массы тела (ИМТ) группы в зависимости от наличия (группа 1; n=30) либо отсутствия (группа 2; n=30) лечебного эффекта МТ, согласно критериям эффективности терапии EULAR (DAS28). Концентрацию МТПГ (суммарный МТПГ и метаболиты МТПГ 1, 2, 3, 4, 5) определяли в эритроцитах методом высокоэффективной жидкостной хроматографии с масс-спектрометрическим детектированием.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Установлено, что уровни суммарного МТПГ и МТПГ 1, 2, 3, 5 в эритроцитах не различались в группах с разным эффектом МТ, при этом доза МТ была сопоставимой у всех больных. В то же время уровень МТПГ4 в первой группе был достоверно выше (26,4±6,1 нмоль/л; р=0,023), чем во второй (22,1±6,8 нмоль/л). Оценка ROC-кривой показала, что значения МТПГ4 &lt;22,5 нмоль/л соответствовали отсутствию лечебного эффекта МТ. Площадь под кривой составила 0,672 (95% доверительный интервал 0,536–0,808; р=0,022). Чувствительность – 77%, специфичность – 53,3%.</p></sec><sec><title>Заключение</title><p>Заключение. Для эффективного лечения больных РА необходимо назначение таких доз МТ, чтобы достигнутый уровень МТПГ4 в эритроцитах был ≥22,5 нмоль/л.</p></sec></abstract><trans-abstract xml:lang="en"><p>Therapeutic control of the methotrexate (MT) polyglutamates (MTPG) level in erythrocytes can be an objective marker of the effective dose of MT prescribed for rheumatoid arthritis (RA).</p><sec><title>Objective</title><p>Objective: to assess the relationship between the level of MTPG in red blood cells and efficacy of the MT dose used by RA patients.</p></sec><sec><title>Subjects and methods</title><p>Subjects and methods. The study included 60 patients with RA (44 women and 16 men over 18 years) who met the criteria of the American College of Rheumatology and the European League Against Rheumatism (ACR/EULAR) 2010 and received MT ≥20 mg/week subcutaneously for ≥12 weeks. The patients were divided into two groups of comparable age, sex, alcohol intake, number of smokers, body mass index (BMI), depending on the presence (group 1; n=30) or absence (group 2; n=30) of the effect of MT, according to the EULAR efficacy criteria (DAS28). The concentration of MTPG (total MTPG and metabolites of MTPG 1, 2, 3, 4, 5) was determined in erythrocytes by high-performance liquid chromatography with mass spectrometric detection.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. It was found that the levels of total MTPG and MTPG1, 2, 3, 5 in erythrocytes did not differ in groups of responders and nonresponders, and the dose of MT was comparable in both groups. At the same time, the level of MTPG4 in the first group was significantly higher (26.4±6.1 nmol/l; p=0.023) than in the second one (22.1±6.8 nmol/l). Analysis of the ROC curve showed that the values of MTPG4 &lt;22.5 nmol/l corresponded to the absence of effect of MT. The area under the curve was 0.672 (95% confidence interval 0.536–0.808 (p=0.022), sensitivity 77%, specificity 53.3%.</p></sec><sec><title>Conclusion</title><p>Conclusion.
