Options for correction of local immune status in patients with chronic endometritis

Abstract: Введение. Наиболее частой причиной повторных неудач имплантации при проведении экстракорпорального оплодотворения является хронический эндометрит с нарушением рецептивности эпителиального слоя полости матки — «тонким» эндометрием. Хроническое воспаление, сопровождающееся аутоиммунными реакциями слизистой, может приводить к извращению иммунного ответа лимфоцитарных клеток с изменением каскада цитокиновых реакций, что препятствует результативности проведения деконтаминационной терапии и, в дальнейшем, способству… Show more

“…Several major factors are currently considered responsible for reproductive dysfunction in CE [20]: this is primarily the abnormal uterine microbiome, as demonstrated by a suffi cient number of microbiological studies [1,[47][48][49][50], the disruption of cytobiochemical and immune processes in the endometrium [28,36,[51][52][53][54], and also confi rmed by the improved fertility following antibacterial therapy in CE patients [34,55,56]. The abnormal uterine microbiome leads to immune deviations primarily affecting the leukocyte pool of immunocompetent cells with a change in the ratio of pro-and anti-infl ammatory cytokines, which results in the reduced implantation capacity of the endometrium and prevents embryo invasion [19,20,22,57]. In addition, prolonged activation of proliferation gene regulation with the downregulation of apoptotic genes (necessary for maintaining adequate endometrial responses) may contribute to the development of proliferative lesions such as polyps [25,34,55,58,61], whereas changes in the vascularization and decidualization of secretory endometrium in the presence of CE may additionally contribute to its receptivity impairment [9,59,60,62].…”
