Problem: Endometriosis is an estrogen-dependent inflammatory disease. Progestins are a first-line treatment for endometriosis via activation of pituitary progesterone receptors and suppression of systemic estrogen: a less than optimal treatment. Increasing evidence is beginning to show that progestins may also influence local endometriotic cells, which may contribute to their clinical efficacy. Method of study: Endometrial stromal cells (ESC) isolated from women with endometriosis were cultured with TNF-α to simulate an inflammatory environment. ESC were treated with the progestins, medroxyprogesterone acetate (MPA), norethisterone acetate (NETA), or dienogest (DNG) and cytokine mRNA production, protein secretion, and cell viability measured. Results: DNG, NETA, and MPA suppressed the secretion of interleukin (IL)-6, IL-8, and monocyte chemotactic protein (MCP)-1 from ESC. DNG and NETA only reduced the TNF-α-stimulated mRNA production. All three progestins suppressed TNF-α-stimulated ESC proliferation. Conclusion: Progestins may influence endometriotic stromal cells altering the inflammatory microenvironment and their clinical efficacy.
