Levonorgestrel-releasing Intrauterine System Compared to Low Dose Combined Oral Contraceptive Pills for Treatment of Adenomyosis: a Randomized Controlled Trial

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.

Conditions

Conditions

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
62

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
  • Phase 2

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 45 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Visual analogue score (VAS) for dysmenorrhea or chronic pelvic pain will be measure before after use LNG_IUS and COCs.
Time Frame: 6 month
6 month

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Menstrual blood loss: assessment of blood loss, measured at the beginning of intervention and for 3 months
Time Frame: 6 month
6 month
