В это же время возникает возрастной дефицит половых гормонов, что считается основой развития метаболических нарушений, в том числе окислительного и карбонильного стресса, а это может быть одной из причин изменения содержания молекул средней массы (МСМ). Цель исследования – установить взаимосвязь между уровнем МСМ и представителями микробиоты кишечника у женщин в менопаузе.</p><sec><title>Материал и методы</title><p>Материал и методы. В исследовании приняли участие 98 женщин, соответствующих следующим критериям: возраст от 45 до 69 лет, аменорея или нарушения менструального цикла, уровень антимюллерова гормона менее 1,2 нг/мл. Критерии исключения: обострение хронических и наличие инфекционных заболеваний, сахарный диабет, прием антибактериальных препаратов в течение трех последних месяцев. Количественную оценку состояния микробиоты кишечника проводили с применением коммерческой тест-системы «Колонофлор-16 (премиум)» методом ПЦР. Содержание МСМ оценивали в сыворотке крови спектрофотометрически при длинах волн 238, 254, 260 и 280 нм с последующим расчетом коэффициентов распределения.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлено наличие линейной зависимости между уровнем МСМ и составом микробиоты кишечника: увеличение общей бактериальной массы, а также количество в образцах кала Bacteroides spp., Roseburia inulinivorans положительно коррелирует с содержанием МСМ, определяемых на всех длинах волн. Бактериальные показатели также ассоциированы с коэффициентами распределения 238/260 и 238/280.</p></sec><sec><title>Заключение</title><p>Заключение. У женщин в менопаузе уровень МСМ взаимосвязан с количественными параметрами микробиоты кишечника и отдельных ее представителей, однако изменения данных показателей нельзя однозначно трактовать как патологические, поскольку это может быть частью естественных физиологических процессов.</p></sec></abstract><trans-abstract xml:lang="en"><p>During menopause, the composition of the gut microbiota undergoes changes. At the same time, age-related deficiency of sex hormones occurs, which is considered the basis for the development of metabolic disorders, including oxidative and carbonyl stress, and this may be one of the reasons for the change in the medium mass molecules (MMM) content. Aim of the study was to establish the relationship between the MMM level and representatives of the gut microbiota in menopausal women.</p><sec><title>Material and methods</title><p>Material and methods. The study involved 98 women who met the following criteria: age from 45 to 69 years, amenorrhea or menstrual irregularities, anti-Müllerian hormone level less than 1.2 ng/ml. Exclusion criteria: exacerbation of chronic and presence of infectious diseases, diabetes mellitus, taking antibacterial drugs during the last three months. A quantitative assessment of the state of the gut microflora was performed using the test system Kolonoflor-16 (premium) by PCR. The MMM content was assessed in blood serum by a spectrophotometry at 238, 254, 260 and 280 nm with subsequent calculation of distribution ratio.</p></sec><sec><title>Results</title><p>Results. The presence of a linear relationship between the MMM content and the gut microbiome composition was revealed: an increase in the total bacterial mass, as well as the content of Bacteroides spp., Roseburia inulinivorans in fecal samples, positively correlates with the MMM level determined at all wavelengths. Bacterial indicators are also associated with distribution ratio 238/260 and 238/280.</p></sec><sec><title>Conclusions</title><p>Conclusions. In menopausal women, the MMM level is interconnected with the volume of gut microbiota and the content of its individual representatives, however, changes in these indicators cannot be unambiguously interpreted as pathological, since this can be part of natural physiological processes.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>средние молекулы</kwd><kwd>кишечный микробиом</kwd><kwd>менопауза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>medium mass molecules</kwd><kwd>gut microbiome</kwd><kwd>menopause</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">Fuhrman B.J., Feigelson H.S., Flores R., Gail M.H., Xu X., Ravel J., Goedert J.J.
