Active clinical trials for "Endometriosis"

The purpose of this study is to determine a difference in participant reported pain after endometriosis surgery in participants given oral metronidazole versus placebo.

The ENDOFERT Study is an open, multicenter, randomized, parallel-group, controlled trial. This study includes patients presenting colorectal DIE and infertility. Patients will be randomized in two parallel-groups; one group underwent complete surgery of colorectal DIE prior to ART and the other group underwent ART alone (ratio 1:1)

To test the hypothesis that estrogen suppression impairs endothelial dysfunction in endometriosis.

The EFFORT study compares the impact on fertility of operation or fertility treatment (IVF, in vitro fertilization) in a multicenter randomized controlled trial. The study population consists of women with colorectal deep infiltrating endometriosis and a pregnancy intention. These women will be randomized to either of the two treatment groups: Group A = Operation or Group B = fertility treatment (IVF). Group A will be further divided postoperatively into spontaneous conception or IVF depending on the Endometriosis Fertility Index score.

Pelvic endometriosis is a complex estrogen-dependent inflammatory syndrome of unknown etiology, altering the microenvironment of the peritoneal cavity and probably endometrial receptivity, and adversely affecting the physiological processes associated with fertilization. Literature data suggest that the distribution of immune system cells in the eutopic endometrium in the presence of endometriosis differs from the physiological state. The functioning of the immune system seems to be significantly modified not only in the foci of endometriosis, but also in the eutopic endometrium, affecting its physiological functions. Chronic endometritis (CE) is a potential factor impairing endometrial receptivity in the course of endometriosis. However, it is not known whether CE is one of the complications of endometriosis or perhaps an element of its pathogenesis. At the moment, endometrial diagnostics is not obligatory in the treatment of endometriosis in women of reproductive age, but it could potentially bring additional benefits and contribute to the improvement of obstetric results and increase the effectiveness of infertility treatment in women with endometriosis.

This is a Phase IIa, open-label, non-randomised and non-placebo-controlled study. The study is designed to evaluate the diagnostic value and safety of a single intravenous dose of SN132D in up to 18 participants with suspected endometriosis. Magnetic resonance imaging (MRI) will be performed pre- and post-infusion of SN132D.

The pathogenesis of endometriosis is very complex as several factors, including genetic, environmental and lifestyle-related factors, are involved in the development, progression and maintenance of the disease. In particular, there are emerging evidences that prostaglandin metabolism, chronic inflammatory processes and circulating estrogen levels are involved in the pathogenesis of endometriosis. Pelvic pain, in particular dysmenorrhea, is the most typical symptom caused by the production of prostaglandins and pain mediators associated with the peritoneal inflammatory state. Metabolomics strives to measure all metabolites, such as sugars, amino acids, acylcarnitines, organic acids, and lipids, present in a given biological sample. Thus, metabolomics represents a reflection of phenotypic changes in an organism in response to the presence of a certain disease, genetic changes, and nutritional, toxicological, environmental, and pharmacological influences, providing a means to more accurately capture exogenous exposures and evaluate endogenous biomarkers. Regarding endometriosis, the targeted metabolomics studies focused mainly on lipids, and the non-targeted studies also identified mainly lipids, amino acids, and intermediary metabolites as the most important variables. The combinations of metabolomics data together with clinical ones are of utmost importance in endometriosis research. This approach might lead to the construction of models/algorithms useful to better define diagnostic/prognostic characteristics of women who have endometriosis, identify environmental and modifiable risk factors, elucidate pathogenetic mechanisms, and contribute to better tailor medical treatments. In particular, metabolomics may provide a means to capture exogenous exposures and evaluate endogenous biomarkers more accurately. The main objective of the present research project is to evaluate potential variations in the plasma metabolomic profile of women affected by endometriosis (as compared with a control group) as a consequence of pathophysiologic alterations associated with this disorder. Secondary objectives are: to evaluate potential variations in the plasma metabolomic profile of endometriosis patients with different phenotypes of the disease: peritoneal endometriosis, ovarian endometriosis, deep infiltrating endometriosis; to evaluate potential variations in the plasma metabolomic profile of endometriosis patients in relation to the presence of endometriosis-related painful symptoms and/or infertility. There is strong evidence that endometriosis has a negative impact on women's quality of life, with severe long-term consequences and substantial social costs. Our findings might lead to the construction of models/algorithms useful to better define diagnostic/prognostic characteristics of women who have endometriosis, identify environmental and modifiable risk factors, elucidate pathogenetic mechanisms, and contribute to better tailoring medical treatments.

Removing in situ and metastasis lesions completely during gynecological surgery is central to reduce the recurrence and death, and the identification of lesions in traditional gynecological surgery often depends on the experience of surgeons. The identification of nerves is often needed in gynecological surgery, such as the obturator nerves in pelvic lymphadenectomy, and the pelvic autonomic nerves in nerve-sparing radical hysterectomy for cervical cancer. Nerve identification also relies heavily on the experience of surgeons. This project aims to realize the identification of lesions and nerves under the navigation of indocyanine green fluorescent imaging, and evaluate the accuracy of fluorescent imaging of lesions and the effectiveness of nerves identification by near-infrared imaging. This project may reduce the recurrence or death caused by residual lesions and postoperative dysfunction caused by nerves injury, thus, improve the survival rate and quality of life for patients with gynecological diseases.

To evaluate the effectiveness of VR as a distraction technique in the management of acute pain and anxiety during ultrasound exam in patients with endometriosis in the outpatient setting.

Endometriosis is a chronic inflammatory disease that affects approximately 10-15% of women of reproductive age. Symptoms include dysmenorrhoea, chronic pelvic pain, dyspareunia and infertility. Removal of the endometriotic cyst (chocolate cyst) by surgery is a well-established treatment for symptomatic relief. However, recurrence of endometriotic cyst after surgical removal of the cyst is up to 30-50% after ovarian surgery. Oral contraceptive pills for 18-24 months after the surgery is widely used as a postoperative hormonal therapy because it has been shown to reduce the chance of recurrence of the endometriotic cyst, but recurrence is still high even after taking oral contraceptive pills. Letrozole is an aromatase inhibitor. There are some preliminary reports that letrozole can cause shrinkage of endometriotic cysts and improve endometriosis-related pelvic pain by reducing oestrogen level, inflammation and stem cell recruitment that may be important in recurrence of endometriotic cyst. This is a randomized double-blinded placebo-controlled trial. The aim of this study is to assess whether taking letrozole in addition to oral contraceptive pills in the first 6 months after laparoscopic surgery (key-hole surgery) to remove the endometriotic cyst can reduce the risk of recurrence compared to oral contraceptive pills alone. The study also involves laboratory parts from a small portion of the endometriotic cyst specimens (removed during laparoscopy ovarian cystectomy) and endometrial biopsy (if the patient agrees) to assess the role of stem cells in the pathogenesis of endometriotic cysts.
