Обследовано 84 пациента с РА умеренной и высокой активности (DAS28 составлял 6,35±0,92), с недостаточной эффективностью терапии базисными противовоспалительными препаратами. Больные получали ЭТЦ 50 мг/нед подкожно в течение 24 нед. Для оценки активности РА использовали суставной счет, оценку пациентом боли и общей активности болезни по 100-миллиметровой визуальной аналоговой шкале (ВАШ), оценку общей активности болезни врачом по ВАШ, DAS28. Функциональный статус определялся с помощью опросников HAQ и RAPID3. Эффективность лечения оценивали по критериям Европейской антиревматической лиги (EULAR) и Американской коллегии ревматологов (ACR). Сывороточная концентрация КП определялась до начала лечения, на 12-й и 25-й неделях. </p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Обнаружено статистически значимое (р&lt;0,0001) снижение концентрации КП к 12-й неделе терапии ЭТЦ. В дальнейшем (к 25-й неделе) уровень КП существенно не менялся. Выявлена корреляция КП с СОЭ, уровнем С-реактивного белка, числом припухших суставов, индексом DAS28. Исходный уровень КП не являлся предиктором в достижении ответа на терапию по критериям EULAR и ACR.В группе не ответивших на лечение по критериям EULAR уровень КП к 25-й неделе повышался, тогда как на фоне клинического улучшения он снижался. У больных, достигших 50% и 70% улучшения по критериям ACR, динамика уровня КП была достоверно лучше, чем у остальных пациентов. </p></sec><sec><title>Заключение</title><p>Заключение. Терапия ЭТЦ приводила к существенному снижению уровня КП и клинико-лабораторных показателей активности РА. Исходная концентрация КП не являлась предиктором в достижении ответа на лечение ЭТЦ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to analyze changes of serum calprotectin (CP) concentration, its relationship to the clinical and laboratory parameters of rheumatoid arthritis (RA) activity, and the significance of baseline CP level for predicting therapeutic response in RA patients treated with etanercept (ETC).</p></sec><sec><title>Subjects and methods</title><p>Subjects and methods. A total of 84 patients with moderate and high RA activity (mean DAS28 6.35±0.92) who had been ineffectively treated with disease-modifying antirheumatic drugs were examined. The patients received ETC 50 mg/week subcutaneously for 34 weeks. To assess RA activity, tender and swollen joint count, pain, patient’s and physician’s assessment of global disease activity on 100-mm visual analogue scale and DAS28 were used. Functional status was evaluated by HAQ and RAPID3. Treatment efficacy was assessed according to the European League against Rheumatism (EULAR) criteria and the American College of Rheumatology (ACR) criteria. Serum concentration of CP was tested before, 12 and 25 weeks after start of therapy.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. There was a statistically significant (p &lt; 0.0001) decrease in CP concentrations after 12 weeks of ETC therapy. Later (after 25 weeks) CP level remained essentially unchanged. CP concentration correlated with erythrocyte sedimentation rate, C-reactive protein level, swollen joint count, and DAS28. Baseline CP level was not a predictor for achieving the therapeutic response according to the EULAR and ACR criteria. In a group of patients unresponsive to treatment according to the EULAR criteria, CP levelrose at 25 weeks whereas it fell during clinical improvement. In the patients achieving ACR 50 and 70% response, changes of CP level were significantly better than those in the other patients.</p></sec><sec><title>Conclusion</title><p>Conclusion. ETC therapy caused a considerable reduction of CP level, clinical and laboratory parameters of RA activity. The baseline concentration of CP was not a predictor for achieving the response to ETC treatment.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кальпротектин</kwd><kwd>СОЭ</kwd><kwd>уровень С-реактивного белка</kwd><kwd>ревматоидный артрит</kwd><kwd>этанерцепт</kwd><kwd>DAS28</kwd><kwd>ACR 20/50/70</kwd></kwd-group><kwd-group xml:lang="en"><kwd>calprotectin</kwd><kwd>erythrocyte sedimentation rate</kwd><kwd>C-reactive protein level</kwd><kwd>rheumatoid arthritis</kwd><kwd>etanercept</kwd><kwd>DAS28</kwd><kwd>ACR 20/50/70</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">Александрова ЕН, Новиков АА, Насонов ЕЛ.
