Active clinical trials for "Endometriosis"

Endometriosis is a common disease, causing significant pain (dysmenorrhea, dysuria, dyspnea, dyspareunia, and chronic pelvic pain) and infertility, drastically reducing patients' quality of life. Endometriosis surgery is often a stressful event for the patient. For that reason, psychological support can improve patients' general health state.

Pathological specimens of 40 women that had been operated for endometriosis will be included in this study. These tissues will be stained with a marker named as PDL-1 in pathological examination. "programmed cell death (PD-1)" is expressed on T cells. The immunotherapies in which antibodies against these PD-1 and its ligands (PDL-1) have been used are accepted as very effective in the treatment of many cancers. If these ligands can be shown in the endometriosis, it will be an important step for the treatment of endometriosis.

Women with PCOS have been observed to be potential diabetics.Recently,American Diabetes Association has suggested screening of women with PCOS for HbA1C.

The purpose of the study is to assess the telomere array of different endometriosis tissue and endometrium from women with endometriosis compared to healthy women. Our hypothesis is that telomere shortening and high telomerase activity will be found in tissues from women with endometriosis.

Our aim was to evaluate the efficacy of examining endometrial biopsy specimens for nerve fibers as a diagnostic test for endometriosis and endometrioma in a double-blind comparison with diagnostic laparoscopy.

Nowadays, one in six couples consults for fertility problems. If the standard examination and tests do not reveal any cause of infertility, the woman may undergo a laparoscopic exploration which reveals endometriosis in more than 50% of cases. Endometriosis is an inflammatory disease defined as the presence of endometrial tissue out of the uterine cavity. It is frequent (1 in 10 women) and associated with a high economic burden (22 billion dollars in 2002 in the USA) and important decrease in quality of life. Physiopathological mechanisms and risk factors for endometriosis are not well identified. A woman with endometriosis is 20 times more at risk of infertility. Fecundity rate of a 25-year-old couple is about 15 to 20% in the general population and only 2 to 10% in case of endometriosis. There are many manifestations of this disease (infertility, pelvic pain) and the anatomo-clinical correlation is not good. The presently used international classification (American Fertility Society revised in 1985, AFSr) does not predict the chance of pregnancy. New scores such as the Endometriosis Fertility Index (EFI) have been proposed to do so, but need to be validated. Treatment for endometriosis-related infertility is not consensual. A prospective cohort study would give access to clinical data of patients followed in our center, so as to identify clinical factors predicting pregnancy and to help treatment decision for women with endometriosis suffering from infertility.

To compare changes in follicular ovarian reserve in women before and six months after laparoscopic operation: endometrioma stripping surgery. Also, to compare follicular ovarian reserve in women with endometrioma(s) with follicular ovarian reserve of healthy infertile women of the same age group.

Ovarian endometriotic cyst (endometrioma) is one of the most common endometriotic lesions, and conservative laparoscopic surgery is the treatment of choice. However, the recurrence after surgery is common. As repetitive surgery leads to morbidities and ovarian function decrease, recurrence after surgery frustrates both patients and clinicians. In this aspect, medical treatments have been offered after surgery to prevent or delay the recurrence. Gonadotropin-releasing hormone agonist (GnRHa) is frequently used in women with advanced endometriosis, but the efficacy is rather controversial. On the other hand, it has been demonstrated that oral contraceptives (OCs) could reduce or delay endometrioma recurrence, but data are still limited. Consequently, no one type of postoperative medical therapy has been shown to be superior in reducing the recurrence of endometrioma. The rationale of postoperative medical therapy is that it could eradicate microscopic lesions which were not found and not treated sufficiently during surgery. Therefore, the maintenance of strongly suppressed condition induced by postoperative GnRHa treatment by addition of OCs could be a promising treatment to prevent the recurrence, but it has not been widely investigated. We performed this retrospective cohort study to evaluate the efficacy of cyclic monophasic low-dose OCs as a maintenance therapy after GnRHa treatment for the suppression of endometrioma recurrence.

Long term treatment of progestin has been demonstrated to have an inhibitory effect on endometrial angiogenesis and the proliferation of endometrial stromal cells. As a result, progestin is now widely employed in the treatment of endometrial cancer, endometrial hyperplasia, and dysfunction uterine bleeding. In the treatment of adenomyosis, however, the beneficial effect of progestin was limited. It might imply that the behavior of endometrial cells in women with adenomyosis is different from that in women without adenomyosis. Our previous study revealed that the expression of killer inhibitory receptors (KIRs) on NK cells was decreased in eutopic endometrium in women with adenomyosis. It may be a compensatory effect in which the NK cytotoxicity is activated in order to wipe out the abnormal endometrial cells that might go out of the eutopic site of endometrium. It implies that the formation of adenomyosis might be due to "abnormal" endometrial tissues, but not the aberrant local immunological dysfunction in myometrium. This finding is compatible with previous reports in which eutopic endometrium obtained from women with endometriosis or adenomyosis was found to behave differently from endometrium in unaffected women. In this study, we try to collect endometrial tissues from women with and without adenomyosis, and then purify the endometrial stromal cells from endometrium. The endometrial stromal cells are cultured for 8 days with the supplement of medroxyprogesterone (MPA) or danazol. Quantification of IL-6 and IL-8 mRNA in endometrial cells, and the concentrations of IL-6 and IL-8 in cultured media will be done with real time RT-PCR and ELISA respectively. The expression of different cytokines of endometrial cells in response to progestin might be further elucidated after our experiment.

Endometriosis can affect quality of life, including physical, psychological and social aspects. It is important to include quality of life measures in evaluating disease severity and response to any given treatment. The 30-item Endometriosis Health Profile (EHP-30) from in-depth interviews with patients with endometriosis is currently the most reliable questionnaire for the measurement of health-related quality of life in women with endometriosis. It includes specific questions addressing the problems faced by patients with endometriosis. The aim of the present study is to validate the Turkish version of EPH 30, a self reported questionnaiere already used internationally, in order to determine the quality of life in women with endometriosis, assess their psychological health and the effectiveness of therapies.
