RESEARCH QUESTION: Are selected cell adhesion molecules useful as urinary biomarkers for diagnosing endometriosis? DESIGN: Prospective, longitudinal study (the Endometriosis Marker Austria) in patients who underwent laparoscopic surgery fo…

STUDY QUESTION: Are increased sVCAM-1 and sICAM-1 levels associated with tumor necrosis factor-alpha-converting enzyme (TACE) activity in endometriosis? SUMMARY ANSWER: Here we provide the first functional evidence that induced TACE activi…

Endometriosis is a common gynaecological condition characterized by severe pelvic pain and/or infertility. The combination of nonspecific symptoms and invasive laparoscopic diagnostics have prompted researchers to evaluate potential biomark…

To evaluate the incidence of endometriosis in polycystic ovary syndrome (PCOS) patients who did not present with any endometriosis symptoms and underwent laparoscopic ovarian drilling (LOD) for clomiphene citrate (CC) resistance, 225 and 63…

RESEARCH QUESTION: As microRNA (miRNA) are stable in circulation, this study tested whether they could serve as putative non-invasive biomarkers for endometriosis, and their expression differences between endometriosis patients and controls…

Endometriosis is a prevalent gynaecological disorder with a still unclear pathogenesis. So far inflammatory mechanisms are associated with disease progression and critical reviews have discussed the so-called 'danger theory' related to endo…

AIM: To evaluate preoperative levels of CA-125 and HE4 in patients with endometriosis-like symptoms and to construct diagnostic models. PATIENTS: Prospective case-control study included 124 endometriosis patients and 97 control patients. …

Much research has gone into developing medications that can be used to alleviate endometriosis-associated symptoms. In addition to already established medications, a new GnRH antagonist, elagolix, is in development. The novelty of this drug…

Endometriosis is characterized by growth of endometrial-like tissue outside the uterine cavity. Since its pathogenesis may involve epigenetic changes, we used Illumina 450K Methylation Beadchips to profile CpG methylation in endometriosis s…

The objective of our pilot clinical, prospective study was to determine the serum levels of mature brain-derived neurotrophic factor, in of women with endometriosis and controls and explore whether mature brain-derived neurotrophic factor i…

STUDY QUESTION: Do cell adhesion molecules play a role in endometriosis, and can they be used as a biomarker for diagnosing endometriosis? SUMMARY ANSWER: Altered expression of vascular cell adhesion molecule-1 (VCAM-1) and intercellular a…

OBJECTIVE: Endometriosis is a benign gynaecological disease, affecting women during their reproductive years. Angiogenesis represents a crucial step in the pathogenesis of endometriosis, because endometriotic lesions require neovascularizat…

BACKGROUND: Current evidence suggests that endometrial-derived stem cells, spilled in the peritoneal cavity via retrograde menstruation, are key players in the establishment of endometriotic lesions. The aim of this study was to determine t…

Endometriosis is a benign but troublesome gynecological condition, characterized by endometrial-like tissue outside the uterine cavity. Lately, the discovery and validation of noninvasive diagnostic biomarkers for endometriosis is one of th…

BACKGROUND: Epithelial to mesenchymal transition (EMT) is a process in which epithelial cells lose polarity and cell-to-cell contacts and acquire the migratory and invasive abilities of mesenchymal cells. These abilities are thought to be p…

OBJECTIVE: In addition to dysmenorrhea, dyspareunia, and subfertility, pain in the lower extremities has been described to be a further complaint in women affected by endometriosis, and lysis of nerve entrapment was thought to be associated…

Endometriosis compromises the quality of life of countless women worldwide and is a leading cause of disability. Clinical symptoms of endometriosis can be very heterogeneous leading to a long interval between onset of symptoms and surgical …

BACKGROUND Enhanced proliferation and survival of eutopic endometrial cells from patients with endometriosis compared with healthy women is associated with abnormal activation of extra-cellular signal-regulated kinases 1 and 2 (ERK1/2). Giv…

OBJECTIVE: To establish the prevalence of endometriosis metastatic to pelvic sentinel lymph nodes (PSLN) in women with ovarian and/or peritoneal endometriosis. DESIGN: Prospective clinical study. SETTING: Academic research institution. P…

BACKGROUND: Initial publications examining the hereditary aspects of endometriosis appeared in the early seventies and demonstrated an up to seven-fold risk for endometriosis in first-degree relatives of endometriosis patients. The aim was …

BACKGROUND: Implanon has been reported to be effective in the treatment of dysmenorrhea. We compared the therapeutic efficacies of depot medroxyprogesterone acetate (DMPA) and Implanon with regard to pain relief in women with endometriosis.…

OBJECTIVE: To evaluate the local matrix metalloproteinase 1 (MMP-1), estrogen receptor (ER) alpha, and ERbeta protein expression in eutopic and dystopic tissue from patients with endometriosis and to compare the endometrial expression patte…

BACKGROUND: Matrix metalloproteinases (MMP) play an essential role in tissue remodelling and menstruation and appear to be regulated by cytokines such as interleukin-1alpha (IL-1alpha). In order to investigate their role in the pathogenesis…

Interleukin (IL)-6 has been implicated in the etiology of endometriosis. A single nucleotide polymorphism (SNP) at position -174 in the IL-6 gene promoter appears to influence IL-6 transcription rates in vitro and basal IL-6 levels in vivo.…
