Official title: Endothelial Dysfunction Among Woman With Endometriosis After Surgical Treatment

Endometriosis is a chronic disease defined as an ectopic endometrial tissue outside the, and associated with chronic inflammatory state and increased risk of atherosclerosis.

Endothelial dysfunction plays an important and elementary role in the development of atherosclerosis.

There are number of non-invasive tests for evaluating the endothelial function. One of them is FMD - "Flow Mediated Dilatation". Clinical studies proved the efficacy of this method in predicting cardio-vascular events in patients with established heart disease and also as an independent risk factor, better than the traditional ones.

An alternative method, developed in recent years, is evaluation of peripheral blood vessels tone - "Peripheral Arterial Tonometry" - (PAT). It evaluates the pulsatile blood volume of the blood vessels in the fingertips during reactive hyperemia. The obtained value "reactive hyperemic index" (RHI) correlates well with FMD as well with coronary arteries endothelial dysfunction.

it well suited as a clinical tool or as a test for a large-scale clinical study.

Endothelial dysfunction has been demonstrated among woman with endometriosis. After surgical removal of endometrial implants there was a substantial improvement in the endothelial function, by imaging (using FMD) and by inflammatory markers

In this study the investigators will follow the endothelial function among women undergoing endometrial implants surgical removal, before and after the surgery, using PAT technology (ENDOPAT system). Inflammatory markers and quality of life parameters will also be evaluated.

The follow-up will include one meeting 6 weeks after the procedure The investigators expect an improvement in the endothelial function among women who had endometriosis implants removal.

Read the detailed description

Endometriosis is a chronic disease defined as an ectopic endometrial tissue outside the uterus, mostly in the pelvis. It is related to major morbidity and infertility. It is also associated with chronic inflammatory state and increased risk of atherosclerosis.

Endothelial dysfunction plays an important and elementary role in the development of atherosclerosis.

There are number of non-invasive tests for evaluating the endothelial function. One of them is FMD - "Flow Mediated Dilatation". It refers to dilation (widening) of an artery when blood flow increases in that artery after An intentional block of the blood flow. Clinical studies proved the efficacy of this method in predicting cardio-vascular events in patients with established heart disease and also as an independent risk factor, better than the traditional ones.

An alternative method, developed in recent years, is evaluation of peripheral blood vessels tone - "Peripheral Arterial Tonometry" - (PAT). It evaluates the pulsatile blood volume of the blood vessels in the fingertips during reactive hyperemia. The obtained value "reactive hyperemic index" (RHI) correlates well with FMD as well with coronary arteries endothelial dysfunction.

The test is performed by attaching two sensors to the patient's fingertips. Using this method requires short training interval, completely user-independent and the accepted result is a quantitive index. Because it takes only 15 minute to complete the test it well suited as a clinical tool or as a test for a large-scale clinical study.

Endothelial dysfunction has been demonstrated among woman with endometriosis. After surgical removal of endometrial implants there was a substantial improvement in the endothelial function, by imaging (using FMD) and by inflammatory markers, so no difference was shown between them and healthy women, 2 years thereafter.

In a large meta-analysis, evaluating 5,547 patients, every 1% improvement in the FMD scale resulted in a 13% decrease in the rate of cardio-vascular events.

In a meta-analysis evaluating 5,547 patients a 13% reduction in the risk to cardio-vascular events was demonstrated for every 1% improvement in the FMD score.

In this study the investigators will follow the endothelial function among women undergoing endometrial implants surgical removal, before and after the surgery, using PAT technology (ENDOPAT system). Inflammatory markers and quality of life parameters will also be evaluated.

The follow-up will include one meeting 6 weeks after the procedure the investigators expect an improvement in the endothelial function among women who had endometriosis implants removal.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • • Endothelial function using ENDOPAT systemDiagnostic test

    All of the participants will follow an non-invasive test for endothelial function using ENDOPAT 2000 device before surgery. A consecutive assessment will be held 6 weeks and 2 years post-surgery, using the same method.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline endothelial function at 6 weeks

    RHI index - "Reactive Hyperemia Index"

    Measured: before and 6 weeks after surgery

  2. Change from baseline inflammatory markers at 6 weeks

    C-reactive protein

    Measured: before and 6 weeks after surgery

Secondary outcomes (2)
  1. Change from baseline pain score at 6 weeks

    visual analog scale (VAS)- scale for patient self-reporting of pain. 0 represents no pain, 1-3 represents mild pain, 4-6 represents moderate pain, 7-10 represents severe pain). a lower pain level 6 weeks after surgery is a better outcome

    Measured: before and 6 weeks after surgery

  2. Change from baseline quality of life score at 6 weeks

    The Short Form (SF-36) Health Survey is a 36-item, patient-reported survey of patient health.The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability. a higher score 6 weeks after surgery is a better outcome

    Measured: before and 6 weeks after surgery

Questions about this trial

What is this clinical trial studying?

A study testing • Endothelial function using ENDOPAT system in people with Endometriosis, run by HaEmek Medical Center, Israel at 1 site in Israel.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 22 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: slow recruitment rate). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline endothelial function at 6 weeks (time frame: before and 6 weeks after surgery). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Sep 2023.
