The controlled cross-sectional study included 33 patients with EGE comprising main group, and 30 healthy women enrolled to control group. All women underwent assessment of hormonal status and cytokine expression levels in peripheral blood. Level of blood hormones estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL) was carried out using enzyme-linked immunosorbent and chemiluminescent assays. Expression levels of cytokines such as interleukin (IL) IL-6, IL-8, tumor necrosis factor alpha (TNF-α) were analyzed by an enzyme-linked immunosorbent assay. Taxonomic composition of intestinal microbiota at the level of phyla and genera was carried out by 16S ribosomal RNA gene sequencing. Microbial community a-diversity, the Chao1, ACE, and Sobs indices were used.</p></sec><sec><title>Results</title><p>Results. The concentration of blood E2 in main group was significantly higher compared to control group. Also, women with EGE had higher plasma concentrations for IL-6, IL-8, IL-17 and TNF-a compared to those in control group (p &lt; 0.001). While analyzing bacterial community a-diversity in main group, Chao1 index was found to be significantly decreased. At the phylum level, the Firmicutes/Bacteroidetes ratio was increased in patients with EGE compared with that in control group. Among the 20 largest genera in patients with EGE, significant abundance was observed for Lachnospira, Blautia, Dorea, Streptococcus, Eubacterium hallii_group paralleled with significant decline in Bifidobacterium and Eubacterium eligens_group. A positive correlation was obtained between estrogen levels and the number of representatives from the genera Eubacterium hallii_group and Streptococcus, IL-8 and Streptococcus, TNF-α and Streptococcus and Lachnospira, as well as a negative correlation between TNF-α and Bifidobacterium.</p></sec><sec><title>Conclusion</title><p>Conclusion. A relation between dysbiotic intestinal alterations and developing endometriosis was found. The identified correlations between altered taxonomic composition of the intestinal microflora and parameters of hormonal and immune status in patients with EGE suggest that intestinal microbiota is involved in pathophysiology of endometriosis.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель: системная оценка особенностей таксономического состава микробиоты кишечника во взаимосвязи с показателями гормонального и иммунного статуса у пациенток с наружным генитальным эндометриозом (НГЭ).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В сравнительное одномоментное исследование были включены 33 пациентки с НГЭ, которые составили основную группу, и 30 здоровых женщин, составивших контрольную группу. Всем женщинам производили оценку гормонального статуса и определение уровней экспрессии цитокинов в периферической крови. Измерение содержания гормонов - эстрадиола (Е2), фолликулостимулирующего гормона (ФСГ), лютеинизирующего гормона (ЛГ), пролактина (ПРЛ) осуществляли с помощью иммуноферментного и хемилюминесцентного анализа. Определение уровней экспрессии цитокинов - интерлейкинов (англ. interleukin, IL) IL-6, IL-8, фактора некроза опухоли альфа (англ. tumor necrosis factor alpha, TNF-α) производили с использованием иммуноферментного анализа. Изучение таксономического состава кишечной микробиоты на уровне фил и родов проводили методом секвенирования гена 16S рибосомальной РНК. Для оценки альфа-разнообразия сообщества использовали индексы Chao1, ACE, Sobs.</p></sec><sec><title>Результаты</title><p>Результаты. Концентрация Е2 в крови пациенток основной группы была статистически значимо выше по сравнению с женщинами контрольной группы. Также у женщин с НГЭ были отмечены более высокие плазменные концентрации IL-6, IL-8, IL-17 и TNF-a по сравнению с аналогичными показателями группы контроля (р &lt; 0,001). При анализе альфа-разнообразия бактериального сообщества в основной группе было установлено достоверное снижение индекса Chao1. На уровне филумов соотношение Firmicutes/Bacteroidetes у пациенток с НГЭ было увеличено по сравнению с таковым в группе контроля. Среди 20 крупнейших родов у пациенток с НГЭ было отмечено статистически значимое повышение численности Lachnospira, Blautia, Dorea, Streptococcus, Eubacterium hallii_group и достоверное снижение Bifidobacterium и Eubacterium eligens_group. Получена положительная корреляция уровня эстрогена с численностью представителей родов Eubacterium hallii_group и Streptococcus, IL-8 - со Streptococcus, TNF-α - со Streptococcus и Lachnospira, а также отрицательная корреляция между TNF-α и Bifidobacterium.</p></sec><sec><title>Заключение</title><p>Заключение. Установлена связь дисбиотических изменений кишечника с развитием эндометриоза. Выявленные корреляции нарушений таксономического состава кишечной микрофлоры с показателями гормонального и иммунного статуса у пациенток с НГЭ указывают на вовлеченность микробиоты кишечника в патофизиологию эндометриоза.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>наружный генитальный эндометриоз</kwd><kwd>НГЭ</kwd><kwd>микробиота кишечника</kwd><kwd>гормональный статус</kwd><kwd>эстрогены</kwd><kwd>цитокины</kwd><kwd>интерлейкины</kwd><kwd>IL</kwd><kwd>фактор некроза опухоли альфа</kwd><kwd>TNF-α</kwd></kwd-group><kwd-group xml:lang="en"><kwd>external genital endometriosis</kwd><kwd>EGE</kwd><kwd>intestinal microbiota</kwd><kwd>hormonal status</kwd><kwd>estrogens</kwd><kwd>cytokines</kwd><kwd>interleukins</kwd><kwd>IL</kwd><kwd>tumor necrosis factor alpha</kwd><kwd>TNF-α</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">Клинические рекомендации - Эндометриоз - 2020 (02.11.2020).
