Active clinical trials for "Adenomyosis"

Adenomyosis is characterized by the appearance of endometrial cells in the muscular layer of the uterus. It affects about 15-20% of the female population. The symptoms of adenomyosis are heavy menstrual bleedings and painful menstruation (dysmenorrhea) and in addition chronic pelvic pain. Subfertility and infertility have been correlated with adenomyosis. Parity, age and uterine abrasion increase the risk of adenomyosis. Hormonal factors such as local hyperestrogenism and elevated levels of prolactin (PRL) have been identified, but autoimmune and mechanical factors are also hypothesized. Regarding treatment, the most effective measure is hysterectomy. As this is a very drastic measure in younger women, levonogestrel-releasing intrauterine devices, Gonadotropin releasing hormone (GnRH)-analogues, Danazol, uterine embolization and endometrial ablation have been tried, but studies are few in number, retrospective, and have small sample sizes. Adenomyosis has so far not been subject to extensive research efforts. The pathogenesis of adenomyosis remains still unclear, there are not many satisfying treatment options and diagnostics include mostly magnetic resonance imaging (MRI) and histology. The investigators designed a series of 3 studies with a broad approach in understanding adenomyosis. This is part 2. In this study the investigators take both tissue samples and blood samples that will be investigated in order to understand the basic processes leading to adenomyosis.

Objective: To investigate the effects of levonorgestrel-releasing intrauterine system (LNG-IUS) for symptomatic adenomyosis. Methods: From December, 2006 to December, 2014, symptomatic patients of adenomyosis diagnosed (with dysmenorrhea and/or menorrhea) by transvaginal ultrasound in outpatient or inpatient clinics of Peking Union Medical College Hospital were given the treatment of LNG-IUS. Before and after placement of LNG-IUS, during each following period, all the parameters were recorded prospectively, including carrying status of IUS, symptoms and scores of dysmenorrhea, menstruation scores, biochemical indicators, physical parameters, menstruation patterns and adverse effects. Primary outcome measures: symptoms and scores of dysmenorrhea and menorrhea Second outcome measures: carrying status of IUS

To date, there is no uniform agreement on the most appropriate therapeutic methods for managing women with uterine adenomyosis and/or adenomyoma who want to preserve their fertility. Management with hormonal treatment that aims to reduce the proliferation of endometrial cells is promising, but there is a paucity of well-designed studies to guide treatment. There is a strong need to develop pharmacological agents that provide an efficient outcome. Gonadotripn releasing hormone analogues (GnRHa) have been used in several studies, to produce a constant hypoestrogenic state in a woman with adenomyosis which cause amenorrhoea, control of pain and uterine shrinkage . Pure antiestrogens, however, may offer some advantage in the treatment of adenomyosis and trials are required to assess its usefulness. Leiomyoma and uterine volumes were successfully reduced by use of aromatase inhibitors (AIs). Assuming aromatase production activity in the adenomyosis lesion, Kimura et al, used GnRHa and an AI concomitantly for treatment of uterine adenomyosis. This lack of information stimulated us to run this trial to compare the efficacy of aromatase inhibitor vs. GnRHa in treating premenopausal women with uterine adenomyosis.

This will be a randomized, double-blind, placebo-controlled, proof-of-mechanism phase 2 trial investigating the effect of quinagolide extended-release vaginal ring on reduction of lesions assessed by high-resolution magnetic resonance imaging in women with endometrioma, deep infiltrating endometriosis, and/or adenomyosis.

Adenomyosis is a disease entity diagnosed when endometrial glands and stroma deep in the myometrium are associated with surrounding myometrial hypertrophy. The finding classically associated with adenomyosis is excessive uterine bleeding accompanied by worsening dysmenorrhea. The advent of endovaginal US has substantially improved the ability to diagnose adenomyosis. Different US features of adenomyosis have been reported, including uterine enlargement not explainable by the presence of leiomyomas, asymmetric thickening of the anterior or posterior myometrial wall, lack of contour abnormality or mass effect, heterogeneous poorly circumscribed areas within the myometrium, anechoic lacunae or cysts of varying sizes, and increased echotexture of the myometrium. Transvaginal power Doppler application is useful in studying the vascular tree of adenomyosis and can aid clinicians in planning the most appropriate therapeutic strategy. The differential diagnosis using power Doppler sonography is based on vascular characteristics. Adenomyosis is characterized by a preserved vascular texture supply that results in dilated spiral arteries running perpendicular toward the myometrium into the endometrial surface. Leiomyomata exhibits a vascular tree that typically circumscribes the solid mass. 2D transvaginal power Doppler angiography should be used to improve diagnostic sensitivity and facilitate appropriate therapeutic intervention. The levonorgestrel-releasing intrauterine system (IUS), Mirena, has been approved in Europe for contraception since 1990. Because of the suppressive effect of levonorgestrel on the endometrium, Mirena has also been proven to be effective for the management of menorrhagia and dysmenorrhea, and as a progestin component in postmenopausal hormone therapy. It was introduced in Taiwan in 1995 as an alternative therapy for idiopathic menorrhagia. Many cases of menorrhagia are caused by adenomyosis, and Mirena was, therefore, introduced for the treatment of adenomyosis in Taiwan. The current study is designed to evaluate the best treatment modality for treatment of adenomyosis clinical by assessment of dysmenorrhea and or chronic pelvic pain by visual analogue scale and menstrual blood loss by menstrual diary, imaging by ultrasound and Doppler indices.

Adenomyosis is a common disease in women aged 40-50 years. It associates with dysmenorrhea and menorrhagia. Hysterectomy was considered the main treatment that could definitively cure this disease. Other treatment options are increasingly offered, including hormonal suppression with gonadotropin-releasing hormone agonists or danazol and endometrial ablation. However, deep adenomyosis responds weakly to the above treatment options, which are commonly not considered for long-term management because of the associated side effects. Dienogest is a progestin medication which is used in birth control pills and in the treatment of endometriosis and adenomyosis. Low-dose combined oral contraceptive (COC) pills have been widely used as the primary treatment for menorrhagia. COCs can also be used to induce endometrial atrophy and to decrease endometrial prostaglandin production, which can consequently improve menorrhagia and dysmenorrhea that are associated with adenomyosis

This clinical trial is designed to study the effectiveness and safety of mifepristone in the treatment of symptomatic adenomyosis with multi center, random, double blind and controlled clinical trials. This multicenter study is performed in 150 subjects who are diagnosed as adenomyosis . Twelve weeks of randomization, allocation concealment, double-blind, placebo-controlled, parallel grouping. Subjects are randomly assigned to one of two treatment groups and received one of the following treatments: Mifepristone tablets of 10mg, 1 tablet daily, oral Placebo, 1 tablet daily, oral

Adenomyosis is defined when the endometrial tissue (gland and stroma) is present within the myometrium . The depth of endometrial penetration which uses in diagnosis of adenomyosis not yet agreed; opinions range from one high power field to 25% of the myometrial thickness. It is a common condition in women aged 40-50 years and is considered an important cause of dysmenorrhea and menorrhagia in around 65 % of cases. Until past few years; hysterectomy was the suggested definitive treatment, however; this may not be acceptable to women not willing to loss their fertility. Many treatment lines were studied and proved their beneficial effect on adenomyosis such as GnRH agonists, danazol, combined oral contraceptive pills, dienogest and finally endometrial ablation. However, these line of treatment are not commonly used because high incidence of side effects and relatively high cost of some of them. The levonorgestrel-releasing intrauterine system (LNG-IUS) was emerged as an effective line for treatment of adenomyosis associated pain and bleeding. It can successfully, within 6 to 12 months, down-regulate the estrogen receptors in adenomyotic tissues which lead to decidualization and atrophy of the adenomyosis . In fact, some adenomyotic women respond well to LNG-IUDs and show high acceptability and satisfaction, on the other hand; a group of women may not respond to LNG-IUDs and opt to remove it and start a new medical or surgical option for treatment. However, factors related to LNG-IUS effectiveness in patients with adenomyosis were not well available. Only one report states that a large uterine volume could be a factor associated with LNG-IUS treatment discontinuation in adenomyotic patient. For this reason; the prediction of the responsiveness to LNG-IUS is interesting issue which should be addressed. The present study examines the hypothesis that patient's data reported at baseline visit before using LNG-IUSfor controlling pain/bleeding with adenomyosis can help the prediction of the responsiveness for this important line of treatment at 6 months follow up visit. Up to our knowledge; no clinical trial had been registered or conducted to predict the responsiveness for LNG-IUS in controlling the pain/ bleeding with adenomyosis.
