PURPOSE: Although studies have suggested a link between gut microbiota and endometriosis pathophysiology, the effects of treatment for endometriosis remain unclear. METHODS: In this prospective observational study, 27 patients with stage II…

Endometriosis, a chronic disease that affects about 10% of women of reproductive age, is characterized by severe pain and growth of endometrium-like tissues outside the uteri. Although several theories have been advanced for the cause of en…

The fibrosis mechanism in endometriosis is not elucidated. We investigated the role of eosinophil in fibrosis of endometriosis. The endometriotic stromal cells (ESCs) and endometrial epithelial cells (EECs) were subjected to in vitro experi…

Human relaxin-2 (H2 relaxin) is a peptide hormone of about 6 kDa, first identified as a reproductive hormone involved in vasoregulation during pregnancy. It has recently attracted strong interest because of its diverse functions, including …

Objectives: This prospective study evaluated whether endometriosis is associated with chronic endometritis (CE) and affects the uterine endometrium microbiome (UEM) in women with repeated implantation failure (RIF). Methods: Forty-three wom…

Objectives: The objective of this study was to observe the influence of laparoscopic adenomyomectomy on perinatal outcomes. Materials and Methods: The retrospective cohort study included 43 pregnant cases with adenomyosis who did not underg…

Abstract Purpose It is unknown whether surgery for endometriosis or recurrence of endometriosis affects obstetric outcomes. Methods A total of 208 pregnant women with a history of endometriosis were analyzed. Patients who had endometriomas …

In endometriosis, M2 MΦs are dominant in endometriotic lesions, but the actual role of M2 MΦ is unclear. CD206 positive (+) MΦ is classified in one of M2 type MΦs and are known to produce cytokines and chemokines. In the present study, we u…

INTRODUCTION: Although various perinatal complications have been reported to be increased in the pregnant patients with adenomyosis, it is not clear what type of patients with adenomyosis is more likely to cause obstetric complications. In …

Sphingosine 1-phosphate (S1P), an inflammatory mediator, is abundantly contained in red blood cells and platelets. We hypothesized that the S1P concentration in the peritoneal cavity would increase especially during the menstrual phase due …

子宮内膜症患者では、腹腔内の免疫環境の異常が指摘されている。Macrophage(MΦ)は、腹腔内の主な免疫細胞で、炎症性疾患である子宮内膜症患者の腹腔内においては、抗炎症・免疫抑制性のM2 MΦが優位と報告されているが、なぜM2 MΦ優位なのか、M2 MΦが子宮内膜症の増悪あるいは抑制因子であるのか、その意義は明らかにされていない。我々は逆流月経血中のalarmin IL-33に着目し、IL-33が腹腔内免疫環境をM2 MΦ優位に誘導する因子の1つであることをin vitr…

In endometriosis, M2 macrophages (MΦ) are dominant and promote the development of endometriosis lesions. However, the factor(s) which induces M2 MΦ are unknown. In the present study, we focused on interleukin (IL)-33, known as an alarmin an…

Background: Relaxin (RLX)-2, produced by the corpus luteum and placenta, is known to be potentially effective in fibrotic diseases of the heart, lungs, kidneys, and bladder; however, its effectiveness in endometriosis has not yet been inves…

Endometrioma is known to be an occurrence site of ovarian cancer, but there is no evidence on how to reduce the risk of canceration. Here, we report three cases of ovarian cancer arising from endometrioma during hormone therapies of GnRH an…

BACKGROUND: Endometriosis is a gynaecological disease exhibiting severe pelvic pain, but the mechanism of pain production remains unknown. Bradykinin (BK) is known as an inflammatory mediator, and shows elevated levels in inflammatory disea…

OBJECTIVE: We investigated α-7 nAchR expression in human peritoneal macrophages and examined whether activation of nAchR might be a new therapy for endometriosis. MATERIALS AND METHODS: Human peritoneal fluid mononuclear cells (PFMC) were s…
