Синдром поликистозных яичников (СПКЯ) – наиболее распространённое эндокринное расстройство среди женщин, являющееся частой причиной репродуктивных нарушений, однако данных об особенностях манифестации хронического эндометрита у пациенток с СПКЯ недостаточно. СПКЯ связан с метаболическим синдромом и ассоциирован с системным хроническим воспалением, однако сведения о роли системного хронического воспаления в патогенезе хронического эндометрита у женщин с СПКЯ отсутствуют.</p></sec><sec><title>Цель работы</title><p>Цель работы: определить клинические и морфологические особенности хронического эндометрита у женщин с синдромом поликистозных яичников и установить роль системного воспаления и гормонов гипоталамо-гипофизарно-овариальной системы при хроническом эндометрите, ассоциированном с СПКЯ.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В ходе кросс-секционного исследования в мае 2017 г. – декабре 2019 г. нами было обследовано 198 женщин репродуктивного возраста (33,71 ± 5,93 года), проходивших ежегодный профилактический осмотр. В работе применялись клинические, инструментальные и лабораторные методы исследования, включающие гормональные, биохимические, иммуногистохимические методы и статистический анализ полученных данных. </p></sec><sec><title>Результаты</title><p>Результаты. Из 198 обследованных женщин, 44 из которых имели СПКЯ, хронический эндометрит был диагностирован у 76 человек, в том числе – у 15 пациенток с СПКЯ. Особенностью проявлений хронического эндометрита при СПКЯ явилось относительное уменьшение продолжительности менструального цикла и меньшая выраженность лимфоидной инфильтрации ткани эндометрия в сравнении с таковыми при хроническом эндометрите, не ассоциированном с СПКЯ. Хронический эндометрит у женщин  репродуктивного возраста не был ассоциирован с изменениями гонадотропинов, пролактина, проявлениями клинической и биохимической  гиперандрогении. Независимо от наличия или отсутствия СПКЯ, хронический эндометрит не сопровождался повышением концентраций С-реактивного белка. Установлено, что женщины, не имеющие хронического эндометрита, имеют относительное повышение индекса массы тела, окружности талии и уровней лептина, в сравнении с пациентками с хроническим эндометритом. Однако эта закономерность характерна, в основном, для женщин, не имеющих СПКЯ.</p></sec><sec><title>Заключение</title><p>Заключение. Специфичность клинических проявлений хронического эндометрита при СПКЯ позволяет рассматривать их как диагностически значимые. Выявленные отрицательные ассоциации хронического эндометрита с индексом массы тела, окружностью талии и лептином требуют дальнейшего изучения роли продуктов жировой ткани в контроле над процессами как локального, так и системного воспаления.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. The prevalence of chronic endometritis among women of reproductive age reaches 68 %. Polycystic ovary syndrome (PCOS) is a common cause of reproductive disorders. Data on the characteristics of the manifestation of chronic endometritis in patients with PCOS are incredibly insufficient. PCOS is known as closely associated with metabolic syndrome and chronic systemic inflammation. However, there is no information on the role of chronic systemic inflammation in the pathogenesis of chronic endometritis in women with PCOS.</p></sec><sec><title>The objective</title><p>The objective. Determination of the clinical and morphological features of chronic endometritis in women  with polycystic ovary syndrome and to establish the role of systemic inflammation and hormones of the  hypothalamic-pituitaryovarian axis in chronic endometritis associated with PCOS. </p></sec><sec><title>Materials and methods</title><p>Materials and methods. We performed a cross-sectional study from May 2017 to December 2019 and examined 198 women of reproductive age (33.71 ± 5.93 years) during annual preventive examinations. We used clinical, instrumental, and laboratory research methods, including hormonal, biochemical,  immunohistochemical techniques, and statistical analysis.</p></sec><sec><title>Results</title><p>Results. Of the 198 women examined chronic endometritis was diagnosed in 76 patients, including 15 patients with PCOS. Chronic endometritis in PCOS is characterized by a relative decrease in the duration of the menstrual cycle and less pronounced lymphoid infiltration of endometrial tissue. The risk of chronic endometritis in women of reproductive age is not associated with changes in gonadotropins, prolactin, and  manifestations of clinical and biochemical hyperandrogenism. Chronic endometritis is not accompanied by an increase in the concentration of C-reactive protein. At the same time, BMI, waist circumference, and leptin are considered «anti-risk» factors for chronic endometritis.</p></sec><sec><title>Conclusion</title><p>Conclusion. The specific clinical manifestations of chronic endometritis in PCOS allows us to consider them as diagnostically significant. The revealed negative associations of chronic endometritis with BMI, waist  circumference, and leptin require further investigation of the role of adipose tissue products in the control of local and systemic inflammation. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хронический эндометрит</kwd><kwd>синдром поликистозных яичников</kwd><kwd>СПКЯ</kwd><kwd>ИМТ</kwd><kwd>лептин</kwd><kwd>С-реактивный белок</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic endometritis</kwd><kwd>polycystic ovary syndrome</kwd><kwd>PCOS</kwd><kwd>BMI</kwd><kwd>leptin</kwd><kwd>C-reactive protein</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">Cicinelli E, Matteo M, Tinelli R, Pinto V, Marinaccio M, Indraccolo U, et al.
