Study Description

Brief Summary

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.

Condition or Disease Intervention/Treatment Phase
  • Diagnostic Test: Endometrial aspiration biopsies for CE diagnosis
N/A

Detailed Description

The aim of the study is:
  1. 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.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Endometriosis + empiric antibiotic therapy

Women undergoing laparoscopic removal of endometriotic foci due to pain/infertility and endometrial aspiration biopsy for diagnosis of CE followed by empirical antibiotic therapy of CE, if confirmed

Diagnostic Test: Endometrial aspiration biopsies for CE diagnosis
1 ml of aspirate will be taken from the uterine cavity for histopathological examination and immunohistochemistry for CE during general anesthesia for scheduled surgery

Active Comparator: Endometriosis + no empiric antibiotic therapy

Women undergoing laparoscopic removal of endometriotic foci due to pain/infertility and endometrial aspiration biopsy for diagnosis of CE without empirical antibiotic therapy of CE, if confirmed

Diagnostic Test: Endometrial aspiration biopsies for CE diagnosis
1 ml of aspirate will be taken from the uterine cavity for histopathological examination and immunohistochemistry for CE during general anesthesia for scheduled surgery

Outcome Measures

Primary Outcome Measures

  1. The incidence and activity of CE in study population of women undergoing surgical treatment for pelvic endometriosis due to pain or infertility [up to 3 months]

    The number of plasma cells/1 High Power Field (HPF) in endometrial stroma collected by aspiration biopsy determined by immunohistochemistry

Secondary Outcome Measures

  1. The correlation of CE activity with endometriosis stage in study population of women undergoing surgical treatment for pelvic endometriosis due to pain or infertility [up to 3 months]

    The correlation between the number of plasma cells/ 1HPF in endometrial stroma and the stage of endometriosis (I-IV) according to the American Society for Reproductive Medicine classification

  2. Comparison of the frequency of persistent CE in the group subjected to postoperative empirical antibiotic therapy and in the untreated group [up to 6 months]

    The number of plasma cells/1 High Power Field (HPF) detected by immunohistochemistryin in endometrial stroma collected by aspiration biopsy 3 months after surgery in the group receiving postoperative empiric antibiotic therapy and in the untreated group
