简要总结
Pelvic endometriosis is a complex estrogen-dependent inflammatory syndrome of unknown etiology, altering the microenvironment of the peritoneal cavity and probably endometrial receptivity, and adversely affecting the physiological processes associated with fertilization. Literature data suggest that the distribution of immune system cells in the eutopic endometrium in the presence of endometriosis differs from the physiological state. The functioning of the immune system seems to be significantly modified not only in the foci of endometriosis, but also in the eutopic endometrium, affecting its physiological functions. Chronic endometritis (CE) is a potential factor impairing endometrial receptivity in the course of endometriosis. However, it is not known whether CE is one of the complications of endometriosis or perhaps an element of its pathogenesis. At the moment, endometrial diagnostics is not obligatory in the treatment of endometriosis in women of reproductive age, but it could potentially bring additional benefits and contribute to the improvement of obstetric results and increase the effectiveness of infertility treatment in women with endometriosis.
详细描述
The aim of the study is:
i) Evaluation of the incidence and activity of CE (expressed as the number of plasma cells / 1 High Power Field, HPF) in women undergoing surgical treatment for pelvic endometriosis due to pain or infertility; ii) Evaluation of the correlation of CE activity (expressed as the number of plasma cells/ 1 HPF) with endometriosis staging according to the American Society for Reproductive Medicine Classification System iii) Evaluation of the impact of surgical removal of pelvic endometriosis foci on CE activity iv) Comparison of the percentage of women with persistent CE after surgery in the subgroup receiving empiric antibiotics (Amoxicillin + Clavulanic Acid 875 mg + 125 mg, twice daily orally for 7 days) and the subgroup without antibiotics. The study will include women aged 18-45 undergoing laparoscopic surgery for pelvic endometriosis. Additionally, an endometrial aspiration biopsy will be performed. Endometriosis will be confirmed by histopathology. The stage of endometriosis will be determined according to revised American Society for Reproductive Medicine Classification. CE will be confirmed by histopathology and immunohistochemical staining with monoclonal murine antibodies against human plasma cells CD138, and will be defined as the presence of plasma cells in the endometrial stroma, the value will be given as the number of plasma cells/1 High Power Field (HPF) and the cut-off will be calculated using the receiver operating characteristic (ROC) curve. A control endometrial biopsy to confirm the effectiveness of empiric antibiotic therapy will be performed up to 3 cycles after the primary procedure.
