Пациенток набирали в исследование в 2023–2024 гг. в 15 клинических центрах 5 федеральных округов Российской Федерации. Включали женщин, которых гинеколог, репродуктолог или терапевт направлял к ревматологу для исключения системного аутоиммунного ревматического заболевания (САРЗ). Исследование предусматривало два визита: первый – скрининговый и второй – завершающий (через 2–6 нед), во время которого проводилась верификация САРЗ. Для анализа данных были использованы методы описательной статистики. Частота признаков в двух независимых группах объектов исследования сравнивалась при помощи χ2 (критерий Пирсона), отношения шансов с 95% доверительным интервалом. Связь уровня антител с клиническими проявлениями оценивали с помощью построения регрессионной модели</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Из 631 обследованной критериям включения в исследование соответствовали 612 (97,0%); 19 женщин были исключены, так как не имели ПРЗ (бесплодие или невынашивание беременности) либо признаков САРЗ. Антинуклеарный фактор (АНФ) определяли у 590 из 612 женщин. Позивность по АНФ выявлена у 238 (40,3%) из 590 пациенток. У 71 из 238 женщин обнаружены антиядерные антитела, у 55 – снижение уровня компонентов комплемента (С3 – у 28 и С4 – у 27). САРЗ диагностировано в 71 (11,6%) случае: в 27 (4,4%) – СКВ (в 23 – достоверная и в 4 – вероятная, неполная), в 36 (5,9%) впервые установлено смешанное заболевание соединительной ткани, в 4 (0,7%) – болезнь Шегрена и еще в 4 (0,7%) – системная склеродермия. Не имели САРЗ 167 (70,2%) из 238 АНФ-позитивных пациенток с ПРЗ.</p></sec><sec><title>Заключение</title><p>Заключение. В многоцентровом пилотном исследовании частота СКВ у пациенток российской популяции с ПРЗ составила 4,4% (27 из 612 женщин), общая частота САРЗ – 11,6% (71 из 612). Позитивность по АНФ встречалась более чем в 3 раза (40,3%) чаще, чем случаи впервые диагностированного САРЗ, что указывает на необходимость проведения дальнейших исследований для уточнения причин появления АНФ у женщин детородного возраста с ПРЗ и их динамического наблюдения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to assess the prevalence of systemic lupus erythematosus (SLE) in the Russian population of patients with reproductive health problems (RHP).</p></sec><sec><title>Material and methods</title><p>Material and methods. Patients were enrolled in 2023–2024 at 15 clinical centers in 5 federal districts of the Russian Federation. Women referred by a gynecologist, reproductive specialist, or general practitioner to a rheumatologist to rule out a systemic autoimmune rheumatic disease (SARD) were included. The study comprised two visits: the first screening visit and the second (final, 2–6 weeks later) visit, during which SARD verification was performed. Descriptive statistics methods were used for data analysis. The frequency of features in two independent study groups was compared using χ2 (Pearson’s test), odds ratios with 95% confidence intervals. The association between antibody levels and clinical manifestations was assessed by constructing a regression model.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. Of 631 women examined, 612 (97.0%) met the inclusion criteria; 19 women were excluded because they did not have RHP (infertility or pregnancy loss) and/or signs of SARD. Antinuclear factor (ANF) was determined in 590 of 612 women. ANF positivity was detected in 238 (40.3%) of 590 patients. Of these 238 women, antinuclear antibodies were detected in 71, and decreased complement component levels were found in 55 (C3 in 28 and C4 in 27). SARD was diagnosed in 71 (11.6%) cases: SLE in 27 (4.4%) (definite in 23 and probable/incomplete in 4), mixed connective tissue disease was newly diagnosed in 36 (5.9%), Sjцgren’s disease in 4 (0.7%), and systemic sclerosis in 4 (0.7%). Among ANF-positive patients with RHP, 167 (70.2%) of 238 had no SARD.</p></sec><sec><title>Conclusion</title><p>Conclusion. In this multicenter pilot study, the frequency of SLE in the Russian population among women with RHP was 4.4% (27 of 612 women), and the overall frequency of SARD was 11.6% (71 of 612). ANF positivity occurred more than three times (40.3%) more often than newly diagnosed SARD cases, indicating the need for further studies to clarify the reasons for ANF occurrence in women of childbearing age with RHP and for their longitudinal follow-up.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>системная красная волчанка</kwd><kwd>системные аутоиммунные ревматические заболевания</kwd><kwd>проблемы репродуктивного здоровья</kwd><kwd>антинуклеарный фактор</kwd><kwd>многоцентровое пилотное исследование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>systemic lupus erythematosus</kwd><kwd>systemic autoimmune rheumatic diseases</kwd><kwd>reproductive health problems</kwd><kwd>antinuclear factor</kwd><kwd>multicenter pilot study</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено при поддержке компании «АстраЗенека».
