STUDY QUESTION: Is mRNA expression of LDL receptors altered in deep bowel endometriotic foci? SUMMARY ANSWER: mRNA expression of LDL receptors is up-regulated in deep bowel endometriotic foci of patients with endometriosis. WHAT IS KNOWN A…

STUDY HYPOTHESIS: Loss of protein BAF250a (ARID1A) expression is present in women with rectovaginal deep-infiltrating endometriosis (DIE) and endometriosis affecting the pelvic sentinel lymph nodes (PSLN). STUDY FINDING: Partial loss of pr…

Endometriosis has clearly three distinct clinical presentations and deep endometriosis, especially compromising the rectosigmoid is probably the most concerning one for both patients and surgeons. Currently, with the available tools, it is …

Chemokines have been associated with endometriosis. Our study was aimed at evaluating the levels of six chemokines--CXCL8 (IL-8), CXCL12 (SDF-1), CCL2 (MCP-1), CCL5 (RANTES), CCL19 (MIP-3β), and CCL21 (6-Ckine)--in the peritoneal fluid (PF)…

INTRODUCTION: Environmental toxicants can act as endocrine disrupters on the female reproductive system. 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is resistant to degradation and due to its lipophilic nature, accumulates in the fat tissue …

BACKGROUND: Deep endometriosis invading the bowel constitutes a major challenge for the gynecologist. In addition to the greater impact on pain, the high incidence of surgical morbidity involved with bowel endometriosis poses a therapeutic …

Endometriosis is a prevalent benign disease, despite sharing several similarities with malignancies, such as the possibility of lymphatic spread. In malignancies, chemokines play a sovereign role in the process of metastasis. Metastasis-rel…

Endometriosis, defined as the presence of endometrial glands and/or stroma outside the uterine cavity, is an estrogen-dependent disease that affects about 10% of reproductive age women. Theories to explain the etiology of endometriosis abou…

Rectosigmoid endometriosis is one of the most advanced forms of the disease affecting 3% to 37% of patients with endometriosis. Some patients are asymptomatic but others can develop severe symptoms such as abdominal and pelvic pain, diarrhe…

Endometriosis is characterized by the presence of endometrial-like tissue located outside the uterine cavity. Recent evidence suggests that endometriosis may be an epigenetic disease, as well as an estrogen-dependent disease. Based on the u…

STUDY OBJECTIVE: To evaluate the external validity of the validated French model of the quality-of-life questionnaire (QOL) SF-36 in predicting improvement after colorectal resection for endometriosis. DESIGN: Italian and Brazilian cohort …

Endometriosis is a benign gynecological disease that is related to immune response alterations. T regulatory cells modulate immune response, and Foxp3 seems to be the best marker of these cells. This study evaluated Foxp3 mRNA expression in…

OBJECTIVE: To evaluate antimüllerian hormone (AMH) and AMH receptor II (AMHRII) mRNA and protein expression in endometrium and in ovarian or deep lesions of women with endometriosis. DESIGN: Prospective study. SETTING: University hospital…

BACKGROUND: Endometriosis is regarded as a complex and heterogeneous disease in which genetic and environmental factors contribute to the phenotype. The Vascular Endothelial Growth Factor (VEGF) plays important roles in the pathogenesis of …

STUDY QUESTION: Can we use chemokines as biomarkers to diagnose patients with endometriosis in clinical practice? SUMMARY ANSWER: Some chemokines, especially CXCL8 (IL-8), CCL-2 (MCP-1) and CCL5 (RANTES), have the potential to work as biom…

Our understanding of the pathogenesis of endometriosis is rapidly evolving as early molecular events are increasingly identified. Endometriosis is associated with increased risk of ovarian cancer and exhibits neoplastic phenotypes including…

Endometriosis is a chronic benign disease that affects women of reproductive age causing abdominal pain and infertility. Its pathogenesis remains obscure despite all the research conducted over the past 100 years. However, there is a consen…

OBJECTIVE: To evaluate serum and peritoneal concentrations of amyloid protein A in women with endometriosis and to compare them with those of women without endometriosis. STUDY DESIGN: A prospective study evaluated 76 women suspected of ha…

BACKGROUND: There is increasing evidence that oxidative stress is one of the key factors for progression of endometriosis. In this prospective controlled trial, we measured 6 different biomarkers of oxidative stress targeting protein, lipid…

OBJECTIVE: To evaluate the expression of chemokines that regulate natural killer (NK) and T-regulatory (T-reg) cell activity in eutopic and ectopic endometrial tissue samples from endometriosis patients. DESIGN: Case-control study (Canadia…

BACKGROUND: Endometriosis is a multifactorial gynecological disease characterized by the presence of functional endometrium-like tissue in ectopic sites. Several studies have focused on elucidating the immunological, endocrine, environmenta…

BACKGROUND: Activin A is a growth factor, produced by the endometrium, whose actions are modulated by the binding protein follistatin. Both proteins are detectable in the peripheral serum and their concentrations may be increased in women w…

OBJECTIVE: To evaluate serum concentrations of CA-125 and soluble CD-23 and to correlate them with clinical symptoms, localization and stage of pelvic endometriosis and histological classification of the disease. METHODS: Blood samples wer…
