研究概览
简要总结
This is a prospective, Single time point, discovery study intending to identify biomarkers that can differentiate endometriosis from other underlying reasons for pelvic pain. Patients undergoing laparoscopy for evaluation of chronic pelvic pain or elective tubal ligation will be enrolled for collection of tissue samples at the time of laparoscopy.
详细描述
This study will be a prospective collection of blood, urine, and endometrial tissue from women with chronic pelvic pain symptoms, with or without infertility, who require evaluation by laparoscopy. Women undergoing laparoscopy for elective tubal ligation will also be investigated similarly and serve as the negative control. Subjects will be queried regarding sociodemographic characteristics, medical and reproductive history, pain and lifestyle as well as assessment for differential diagnoses such as interstitial cystitis and idiopathic bowel syndrome. Endometriosis severity will be captured by rASRM staging during laparoscopy.

结局指标
主要结局
The identification of biomarker(s) that are differentially expressed in endometriosis in the context of pelvic pain
时间窗: Baseline (pre-operative)
The primary variables will be the DiscoveryMAP analytes identified in blood and/or urine and the mRNA transcriptome in endometrial tissue. DiscoveryMAP is a comprehensive, quantitative platform of immunoassays evaluating multiple analytes in various body system categories: cytokines, chemokines, metabolic markers, hormones, growth factors, tissue remodeling proteins, angiogenesis markers, acute phase reactants, and cancer markers
次要结局
- The identification of biomarker(s) that are associated with endometriosis severity(Baseline (pre-operative))
