Материал и методы. Исследование проведено в рамках программы РЕМАРКА (Российское исслЕдование МетотрексАта и биологических препаратов при Раннем аКтивном Артрите). Включены 85 пациентов с очень ранним РА с длительностью симптомов не более 6 мес, не получавших базисные противовоспалительные препараты (БПВП) и генно-инженерные биологические препараты (ГИБП). Результаты и обсуждение. При анализе распределения генотипов и аллелей полиморфизма rs7574865 гена STAT4 показано, что частоты генотипов G/G, G/T и T/T различаются на уровне выраженной тенденции к статистической значимости между больными РА и контрольной группой (р=0,05). Частота минорного аллеля Т при РА статистически достоверно превышает таковую в группе контроля, и данный аллель ассоциирован с предрасположенностью к развитию РА [отношение шансов (ОШ) 1,7; 95% доверительный интервал (ДИ) 1,1–2,8; p=0,03]. При исследовании взаимосвязи «генотип – фенотип» полиморфизм гена STAT4 коррелировал с эрозивным поражением суставов (r2=0,289; p=0,008). У носителей гомозиготного генотипа TT количество эрозий при включении в исследование было достоверно выше по сравнению с носителями генотипов GG/GT (медиана 5,50 [0,754; 7,5] и 0,00 [0,00; 2,00] соответственно; p=0,003). Риск развития эрозий также связан с полиморфизмом гена STAT4 (ОШ 8,6; 95% ДИ 1,0–204,9; p=0,03). Было выявлено различие в количественном содержании АЦЦП в зависимости от полиморфизма гена STAT4: у носителей хотя бы одного минорного аллеля T (G/T+T/T) концентрация АЦЦП статистически значимо превышала таковую у носителей гомозиготного генотипа GG: 248,97±151,00 и 179,51±147,01 Ед/мл соответственно; p=0,048). Заключение. Проведенное исследование показало, что у российских пациентов с очень ранним РА полиморфизм rs7574865 гена STAT4 ассоциирован как с предрасположенностью к заболеванию, так и с прогностически неблагоприятными проявлениями (фенотипами) заболевания, а именно – развитием эрозий на ранних сроках болезни и повышением уровня АЦЦП.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study was investigation of association of the rs7574865 polymorphism of STAT4 gene (Signal Transducer and Activator of Transcription 4, a family of signal transduction and transcription activation molecules 4) with very early rheumatoid arthritis (RA) in Russian patients, and the study of the relationship of "phenotype – genotype", particularly of positivity for antibodies to cyclic citrullinated peptides (ACCP), their concentration, the presence of erosive joint damage at inclusion in patients the study with the STAT4 gene polymorphism. Material and methods. The study was conducted in the framework of the program REMARKA (Russian study of Methotrexate and biological drugs in Early active Arthritis). 85 patients with very early RA with a duration of symptoms no more than 6 months, not receiving disease modifying anti-rheumatic drugs (DMARD) and biologicals were included. Results and discussion. The analysis of the distribution of genotypes and alleles of STAT4 rs7574865 polymorphism showed that the frequencies of g/G, G/T and T/T genotypes differ at the level of the prominent tendency to statistical significance between patients with RA and the control group (p=0.05). The frequency of minor allele T in RA is significantly higher than that in the control group, and this allele is associated with a predisposition to RA [odds ratio (OR) 1.7; 95% confidence interval (CI) 1.1–2.8; p=0.03]. In the study of the "genotype – phenotype" relationship, STAT4 gene polymorphism correlated with erosive joint damage (r2=0.289; p=0.008). In carriers of the homozygous genotype TT, the number of erosions at inclusion in the study was significantly higher compared with carriers of genotypes GG/GT (median 5.50 [0.754; 7.5] and 0.00 [0.00; 2.00], respectively; p=0.003). The risk of erosion is also associated with the polymorphism of the STAT4 gene (OR 8.6; 95% CI 1.0–204.9; p=0.03). A difference of the ACCP level depending on STAT4 gene polymorphism was revealed: carriers of at least one minor allele T (G/T+T/T) had significantly higher concentration of ACCP than that in carriers of homozygous GG genotype: 248.97±151.00 and 179.51±147.01 U/ml, respectively; p=0.048).</p><p>Conclusion. The study showed that in Russian patients with very early RA, the STAT4 gene rs7574865 polymorphism is associated with both predisposition to the disease and prognostically unfavorable manifestations (phenotypes) of the disease, namely, with the development of erosion in the early stages of the disease and an increase of the ACCP level.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>ген STAT4</kwd><kwd>однонуклеотидный полиморфизм</kwd><kwd>деструктивное поражение суставов</kwd><kwd>антитела к циклическим цитруллинированным пептидам</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>STAT4 gene</kwd><kwd>single nucleotide polymorphism</kwd><kwd>destructive joint damage</kwd><kwd>antibodies to cyclic citrullinated peptides</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.
