Однако результаты исследований, посвященных изучению ассоциаций между этими полиморфизмами и риском развития СКВ у детей, неоднозначны и малочисленны.</p><p>Цель исследования – проверка гипотезы о возможной связи полиморфизма rs10499194 гена TNFA1P3 и rs1800629 гена TNF-α с предрасположенностью к ювенильной СКВ (юСКВ) и ее клиническим фенотипам в российской детской популяции.</p><sec><title>Материал и методы</title><p>Материал и методы. Оба полиморфизма были изучены методом аллель-специфической полимеразной цепной реакции в реальном времени у 63 детей (15 мальчиков и 48 девочек) с достоверным диагнозом юСКВ, средний возраст которых составил 12,3±3,2 года (3–17 лет), а средняя длительность заболевания – 4,1±2,4 года, В качестве контроля были использованы данные о частоте генотипов и аллелей соответствующих генных полиморфизмов TNFA1P3 и TNF-α у 309 здоровых неродственных доноров крови в возрасте старше 18 лет (20–45 лет).</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Исследование показало, что частота мутантного аллеля rs10499194Т гена TNFA1P3 у пациентов с юСКВ была значимо ниже по сравнению с контролем (20,6 и 30,7%; р=0,023), а его носительство незначительно снижало риск развития СКВ (отношение шансов, ОШ 0,58; 95% доверительный интервал, ДИ 0,32–1,05; р=0,053). Частота мутантного аллеля rs1800629A гена TNF-α была незначительно выше при юСКВ по сравнению с контролем (соответственно 38,1 и 26,2%; р=0,056), а его носительство незначительно повышало риск развития СКВ (ОШ 1,73; 95% ДИ 0,93–3,16; р=0,056). Анализ распределения частот генотипов rs10499194 в группах пациентов с артритом и без такового выявил значимые различия (р=0,003). Носительство генотипов с мутантным аллелем Т (СТ+ТТ генотипы) при юСКВ статистически значимо снижало риск развития артрита (р=0,003). В то же время у носителей хотя бы одного аллеля С риск возникновения артрита был в 3,76 раз выше, чем у носителей другого аллеля (р=0,006). Не выявлено связи rs1800629 полиморфизма гена TNF-α с клиническими фенотипами юСКВ.</p></sec><sec><title>Заключение</title><p>Заключение. Мутантный аллель rs10499194T статистически значимо снижает риск развития артрита как одного из клинических проявлений юСКВ, а мутантный аллель rs1800629А гена TNF-α связан с тенденцией к повышению риска развития юСКВ.</p></sec></abstract><trans-abstract xml:lang="en"><p>Numerous recent studies have shown that TNFAIP3 and TNF-α gene polymorphisms are associated with susceptibility to certain autoimmune and inflammatory diseases, including systemic lupus erythematosus (SLE), systemic scleroderma, rheumatoid arthritis, psoriasis, etc. However, the results of studies on associations between these polymorphisms and the risk of developing SLE in children are ambiguous and few in number.</p><sec><title>Objective</title><p>Objective: to test the hypothesis of a possible association between the rs10499194 polymorphism of the TNFA1P3 gene and the rs1800629 polymorphism of the TNF-α gene with susceptibility to juvenile SLE (jSLE) and its clinical phenotypes in the Russian pediatric population.</p></sec><sec><title>Material and methods</title><p>Material and methods. Both polymorphisms were studied by allele-specific real-time polymerase chain reaction in 63 children (15 boys and 48 girls) with a confirmed diagnosis of jSLE, whose mean age was 12.3±3.2 years (3–17 years), and the mean duration of the disease was 4.1±2.4 years. Data on the frequency of genotypes and alleles of the corresponding TNFA1P3 and TNF-α gene polymorphisms in 309 healthy unrelated blood donors over the age of 18 years (20–45 years) were used as controls.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The study showed that the frequency of the rs10499194T mutant allele of the TNFA1P3 gene in patients with jSLE was significantly lower compared to the control (20.6 and 30.7%; p=0.023), and its carriage slightly reduced the risk of developing SLE (odds ratio, OR 0.58; 95% confidence interval, CI 0.32–1.05, p=0.053). The frequency of the rs1800629A mutant allele of the TNF-α gene was slightly higher in jSLE compared with controls (38.1 and 26.2%, respectively; p=0.056), and its carriage slightly increased the risk of developing SLE (OR 1.73; 95% CI 0.93–3.16; p=0.056). An analysis of the frequency distribution of the rs10499194 genotypes in groups of patients with and without arthritis revealed significant differences (p=0.003). Carrying genotypes with the mutant T allele (CT+TT genotypes) in jSLE significantly reduced the risk of developing of arthritis (p=0.003). At the same time, the risk of arthritis in carriers of at least one C allele was 3.76 times higher than in carriers of the other allele (p=0.006). No relationship was found between the rs1800629 TNF-α gene polymorphism and the clinical phenotypes of jSLE.</p></sec><sec><title>Conclusion</title><p>Conclusion. The rs10499194T mutant allele statistically significant reduces the risk of arthritis development as one of the clinical manifestations of jSLE, and the rs1800629A mutant allele of the TNF-α gene is associated with a tendency to increase the risk of jSLE.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>системная красная волчанка с ювенильным началом</kwd><kwd>ген TNFA1P3</kwd><kwd>полиморфизм rs10499194</kwd><kwd>ген TNF-α</kwd><kwd>полиморфизм rs1800629</kwd><kwd>клинический фенотип</kwd><kwd>артрит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>systemic lupus erythematosus with juvenile onset</kwd><kwd>TNFA1P3 gene</kwd><kwd>polymorphism rs10499194</kwd><kwd>TNF-α gene</kwd><kwd>polymorphism rs1800629</kwd><kwd>clinical phenotype</kwd><kwd>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">Rahman A, Isenberg DA.
