About this study

The incidence of venous thrombosis (venous thromboembolic disease: VTE) in women of childbearing age in France is in the order of 0.3 to 0.5 / 1000 women / year. It is a rare disease, but the majority of events occurring in women of childbearing age are associated with a particular hormonal context (mainly pregnancy and hormonal contraception). VTE is a multifactorial disease and the risk depends on the simultaneous presence of several triggers.

Read the detailed description

Certain frequent gynecological pathologies are emerging in the literature as new venous thrombotic risk factors independently of hormonal treatment. Indeed, in endometriosis, the prevalence of which is estimated to be around 10%, biological data are in favor of hypercoagulability. Only one epidemiological study has analyzed this parameter. It is a Japanese cohort study in 103,070 pregnant women including 77 VTE during pregnancy. Endometriosis and recurrent pregnancy loss (RPL) were identified as risk factors for VTE (OR: 2.70 (95%CI, 1.21-6.00) for endometriosis and 6.13 (95% 2.48-15.16) for RPL. In polycystic ovary syndrome (PCOS), whose prevalence is estimated at 7-12%, the associated risk of VTE is better known (OR 1.89, 95%CI 1.60-2.24) and was the subject of a recently published meta-analysis in which the principal investigator collaborated. To the investigators knowledge, no study describes the prevalence of gynecological pathologies in women with VTE.

Concerning hormonal contraception, estrogen-progestin contraception (EPC) is widely used in France and is associated with an increase in the risk of VTE of a factor of 3 to 6. After a venous thrombotic episode, EPC is contraindicated, and non-hormonal or progestin-only contraception (POC) can be used. Nevertheless, to date, few studies have focused on the management of hormonal contraceptive treatment at the time of a VTE episode. Moreover, the contraceptive options presented to patients are often based on multiple actors (vascular physicians, gynaecologists, midwives, general practitioners, etc.) and the experience of the VTE episode, for both patients and prescribers, may influence the contraceptive options proposed or chosen, as well as their compliance.

    Measured: Day 1

Secondary outcomes (2)
  1. Analyze the characteristics of VTE according to the presence or absence of a gynecological pathology

    Characteristics of VTE

    Measured: Day 1

  2. Describe of hormone therapy used after VTE

    Percentage of women using hormonal treatment

    Measured: Day 1

Questions about this trial

What is this clinical trial studying?

An observational study of Venous Thromboembolism, run by Fondation Hôpital Saint-Joseph at 1 site in France.

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 2 inclusion and 4 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: finished, as of the sponsor's last update on 8 Mar 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 France. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Retrospectively assess the prevalence of gynecological pathologies in women at the time of VTE (time frame: Day 1). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04920487, which also lists 1 linked publication.

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 8 Mar 2023.
