Brief Summary

Accumulating evidence suggests that the peritoneal microenvironment of women affected by endometriosis undergoes a number of local inflammatory-reparative phenomena, with the involvement of resident macrophages, and the attraction and recruitment of peripheral mononuclear cells (monocytes and lymphocytes) from the blood into the peritoneal cavity: during endometriosis a breakdown occurs in endometrial and peritoneal homeostasis caused by cytokine-addressed cell proliferation and dysregulation of apoptosis. The surrounding microenvironment may address the macrophage plasticity towards a transient and reversible polarization. These polarized phenotypes reflects the proinflammatory or anti-inflammatory status and may change over the time. They could be functionally classified in two main populations: "classically activated" macrophages (M1) and "alternatively activated" macrophages (M2). Considering that published data so far are still not robust enough to drawn firm conclusion, the aim of this research project will be to evaluate M1 and M2 macrophages in endometriotic tissue from women affected by endometriosis at different stages.

Outcome Measures

Primary Outcomes (1)

  • Quantification of M1 and M2 macrophages in endometriotic tissue for each stage of endometriosis.

    To assess surface expression of macrophage markers, endometrial tissue cells will be stained for flow cytometry with fluorochrome-conjugated monoclonal antibodies against CD14, CD68, CCR7 and CD80 to identify M1, whereas fluorochrome-conjugated monoclonal antibodies against CD14, CD68, CD163 and CD206 to identify M2.

    Day 1

Secondary Outcomes (2)

  • Correlation of M1 and M2 macrophages quantity in endometriotic tissue to the presence of endometriosis-associated infertility.

    Day 1

  • Correlation of M1 and M2 macrophages quantity in endometriotic tissue to the presence of endometriosis-associated chronic pelvic pain.

    Day 1

Study Arms (2)

Endometriosis

Patients affected by endometriosis (histologically confirmed) at different stages, who will undergo laparoscopic surgery.

Diagnostic Test: Evaluation of M1 and M2 macrophages by flow cytometry.

Ovarian functional cysts

Patients affected by ovarian functional cysts, who will undergo laparoscopic surgery.

Diagnostic Test: Evaluation of M1 and M2 macrophages by flow cytometry.

Interventions

To assess surface expression of macrophage markers, tissue samples will be stained for flow cytometry with fluorochrome-conjugated monoclonal antibodies against CD14, CD68, CCR7 and CD80 to identify M1, whereas fluorochrome-conjugated monoclonal antibodies against CD14, CD68, CD163 and CD206 to identify M2.
