title: Cytokine Profiling in the Eutopic Endometrium of Adenomyosis During the Implantation Window After Ovarian Stimulation.
abstract: In this study, we aimed to clarify the inflammatory cytokine profile of endometrium in patients with adenomyosis during the implantation window after ovarian stimulation. Eighteen patients with adenomyosis and 24 control patients undergoing in vitro fertilization treatment were included in this prospective case-control study. Regular gonadotropin-releasing hormone antagonist protocol was used for ovarian stimulation. Endometrial samples were obtained 7 days after human chorionic gonadotropin (hCG) injection (hCG + 7). Cytokine levels in endometrium secretions from women with and without adenomyosis were assayed by multiplex immunoassay, levels of interleukin (IL) 6 (25.9 ± 6.6 vs 12.4 ± 3.4 pg/mL; P = .001), IL-10 (10.4 ± 2.9 vs 15.6 ± 4.2 pg/mL; P = .001), IL-17 (11.9 ± 3.0 vs 14.2 ± 3.9 pg/mL; P = .046), interferon-γ (11.7 ± 3.5 vs 8.0 ± 3.4 pg/mL; P = .001), and monocyte chemoattractant protein-1 (MCP-1; 37.1 ± 6.5 vs 16.4 ± 3.2 pg/mL; P = .001) were significantly different between patients with adenomyosis and control groups, respectively. Immunohistochemistry and quantitative real-time polymerase chain reaction showed that CD-68+, IL-6, and MCP-1 expression were higher and IL-10 was lower in adenomyosis endometrium epithelia compared to controls. In conclusion, within the implantation window of ovarian stimulation cycles, macrophages, IL-6, IL-10, and MCP-1 are expressed differently in the endometrium of women with adenomyosis, which may correlate with compromised endometrium receptivity. We postulated that cytokines of endometrial secretions expressed differently in patients with adenomyosis may contribute to impaired endometrium receptivity in these patients.
