Цель настоящего исследования – выявить частоту встречаемости дефицита и недостаточности витамина D у пациентов с РА, установить ассоциации плазменной концентрации 25(ОН)D с показателями активности заболевания. В исследование включены 156 пациентов с РА, средний возраст 60,2 ± 13,9 лет. Пациентам проводилась оценка клинической картины заболевания, выполнялось определение уровня ревматоидного фактора (РФ), С-реактивного белка (СРБ), содержание общего витамина D (25(OH)D), антител к циклическому цитруллинированному пептиду (АЦЦП). Активности РА оценивались с применением расчетных индексов DAS28 (Disease Activity Score), SDAI (Simplified Disease Activity Index) и CDAI (Clinical Disease Activity Index). Средние уровни 25(OH)D в обследованной выборке составили 25,2 ± 13,2 нг/мл. Нормальные показатели витамина D, его недостаточность и дефицит наблюдались у 47 (30,3 %), 45 (28,7 %) и 64 (40,7 %) пациентов соответственно. Результаты проведенного исследования свидетельствуют о высокой распространенности гиповитаминоза D у пациентов с РА. Низкий уровень 25(OH)D у пациентов с РА ассоциируется с более высокими показателями активности заболевания по индексам DAS28, SDAI и СDAI и большим количеством болезненных суставов. Назначение витамина D целесообразно использовать в качестве дополнительной терапии у пациентов с активным РА с потенциальной иммуномодулирующей целью, а также для профилактики и лечения нарушений костного метаболизма.</p></abstract><trans-abstract xml:lang="en"><p>Vitamin D deficiency is an important environmental risk factor that influences the prevalence and severity of several autoimmune diseases, including rheumatoid arthritis (RA). The aim of this study was to determine the incidence of vitamin D insufficiency and deficiency in patients with RA, to establish the relationship between serum vitamin D levels and indicators of disease activity. 156 patients with RA were included in the study, mean age 60.2 ± 13.9 years. Assessment of clinical status was performed, serum concentrations of rheumatoid factor (RF), C-reactive protein (CRP), total vitamin D (25(OH)D), antibodies to cyclic citrullinated peptide (ACCP) were determined. RA disease activity was evaluated using DAS28 (disease activity score), SDAI (Simplified Disease Activity Index) и CDAI (Clinical Disease Activity Index) scores. Average levels of 25(OH)D in the surveyed sample were 25.2 ± 13.2 ng/ml. The results of the study indicate a high prevalence of vitamin D deficiency in patients with RA. Normal indicators of vitamin D, its insufficiency and deficiency were observed in 47 (30.3 %), 45 (28.7 %) and 64 (40.7 %) patients, respectively. Low level of serum 25(OH)D was associated with higher indices of RA activity according to DAS28, SDAI and CDAI, as well as with greater tender joint count. Vitamin D should be prescribed as an adjunctive therapy in patients with active RA due to its potential immunomodulatory effect, as well as for the prevention and treatment of bone metabolism disorders.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>активность</kwd><kwd>витамин D</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>disease activity</kwd><kwd>vitamin D</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">Asystematic review of vitamin D status in populations worldwide / J.
