В исследование включено 33 больных РА, получающих МТ (средний возраст 53,2±11,7 года), у которых проводили терапевтический лекарственный мониторинг с определением концентрации свободного МТ, а также МТ полиглутаматов (МТПГ) с 2, 3 и 4 глутаматными остатками (МТПГ 2–4) в ЭР и МО с помощью тандемной хроматомасс-спектрометрии после 4, 12 и 24 нед терапии.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Через 12 нед концентрация МТПГ4 в МО была выше у больных, получавших статины, а концентрация МТ и МТПГ2 в ЭР оказалась значимо ниже у курильщиков. На 24-й неделе в ЭР у больных старшего возраста отмечены более высокий уровень МТ и более низкая концентрация МТПГ4.</p></sec><sec><title>Заключение</title><p>Заключение. После 24 нед терапии в ЭР у больных старшего возраста концентрация МТПГ4 была ниже, а уровень МТ – выше, чем у остальных пациентов, что подтверждает данные о более медленном метаболизме МТ в пожилом возрасте. Прием статинов, вероятно, оказывает положительное влияние на накопление МТПГ. У курильщиков выявлена статистически значимо более низкая концентрация МТПГ в ЭР на 12-й неделе терапии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to assess the time course of changes in the concentration of methotrexate (MTX) and its main metabolites in the red blood cells (RBC) and mononuclear cells (MNC) of patients with rheumatoid arthritis (RA), by taking into account individual characteristics (age, statin therapy, and smoking).</p></sec><sec><title>Patients and methods</title><p>Patients and methods. The investigation enrolled 33 MTX-treated patients (mean age 53.2±11.7 years) with RA, who underwent therapeutic drug monitoring to measure the RBC and MNC concentrations of free MTX and MTX polyglutamates (MTXPGs) with 2, 3, and 4 glutamate residues (MTXPG 2–4) in using tandem chromatomass spectrometry after 4, 12, and 24 weeks of therapy.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. Following 12 weeks, the concentration of MTXPG4 in the MNC was higher in patients taking statins, while that of MTX and MTXPG2 in the RBC were significantly lower than in smokers. At 24 weeks, older patients were observed to have a higher MTX level and a lower MTXPG4 concentration in the RBC.</p></sec><sec><title>Conclusion</title><p>Conclusion. After 24 weeks of therapy, the RBC concentration of MTPG4 was lower and that of MTX was higher in older patients than in others, which confirms data on a slower MTX metabolism in the elderly. The use of statins is likely to have a positive impact on the accumulation of MTXPG. There is a statistically significantly lower RBC concentration of MTXPG in at 12 weeks of therapy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>терапевтический лекарственный мониторинг</kwd><kwd>метотрексат</kwd><kwd>ревматоидный артрит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>therapeutic drug monitoring</kwd><kwd>methotrexate</kwd><kwd>rheumatoid arthritis</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">Stamp LK, Barclay M.
