Background: The widespread prevalence of infertility, the low effectiveness of assisted reproductive technologies (ART), and the high incidence of chronic endometritis (CE) in infertile women determine the relevance of the considered problem. The aim of the study was to determine the clinical and anamnestic, laboratory, and instrumental features of CE associated with infertility and unsuccessful IVF cycles in women of reproductive age. Materials and methods: The study enrollred 150 women of reproductive age with morphologically established CE (main group, n=120) and without CE (control group, n=30). A subgroup I of the main group included 64 patients with infertility and IVF failures, a subgroup II - 56 fertile women. In addition to anamnesis collection and identification of CE clinical features, all patients underwent infectious screening, immunological and immunohistochemical analysis, ultrasound examination of pelvic organs with dopplerometry, and office hysteroscopy. A comparative analysis of the data obtained from subgroups of the main group was conducted. Results: Histological study of endometrial pipelle-biopsy specimens on the 7-10th day of the cycle revealed CE in all patients of the main group. We found prevalence of mean duration of CE in the subgroup I relative to subgroup II - 5.5±0.06 years and 2.4±0.07 years, respectively (p<0.001). Infectious screening showed that 58 (90.6%) patients of the I subgroup had sterile endometrial seeding which was 16.9 times higher than in subgroup II (p<0.0001). Immunological analysis determined the presence of AEAT in all patients of the subgroup I, 43 of which (67.2%) were above 265 U/ml, while 51 (91.1%) of subgroup II had no AEAT (p<0.001). Immunohistochemical analysis of the endometrium on the 18th-24th day of the cycle established high expression of CD16, CD20, CD56, and HLADRII in 58 (90.6%) patients of the subgroup I, whereas in 54 patients (96.4%) of II subgroup high expression of CD16 and CD20 with low amount of CD56- and HLA-DRII-positive cells was registered (p<0.001). We determined prognostically significant clinical and anamnestic risk factors predisposing to the development of infertility in patients with CE (p<0, 05). We revealed certain echographic, dopplerometric, and hysteroscopic criteria of CE demonstrating the critical disruption of endometrial receptivity in infertile women. Conclusion: Most patients (90.6%) with infertility had autoimmune component of CE characterized by prolonged (more than 5 years) course, high serum level of AEAT, sterile endometrial crops, and high expression of inflammation markers CD16, CD20, CD56 and HLA-DRII .
