ENDOSAS: Assessment of the Occurrence of Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) in Women Suffering From Endometriosis
Study Details
Study Description
Brief Summary
This observational study aims at establishing the proportion of patients suffering from endometriosis and for whom an Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) diagnosis is established.
The study participation will be offered to endometriosis patients displaying symptoms that may suggest an underlying OSAHS.
OSAHS diagnosis will be made according to standard of care practice and patients will be followed up to 12 months after initiating the OSAHS treatment to fill in questionnaires assessing the impact of OSAHS treatment on various endometriosis-related symptoms

Detailed Description
The overall prevalence of endometriosis varies between 1% and 8% depending on the studies, and endometriosis would affect approximately one in 10 women in France. In 2022, A report was submitted to the President of the French Republic for the development of a national strategy to fight against endometriosis, proposing in particular the development of a national epidemiological database and an "easily identifiable and accessible diagnosis pathway throughout the territory".
The experience at the investigational site has led to note a significant prevalence of obstructive sleep apnea hypopnea syndrome (OSAHS) in the population of patients with endometriosis. There are no published studies on the relationships between OSAHS and endometriosis. However, intermittent hypoxemia and endothelial dysfunction are two important consequences of OSAHS that may be related to endometriosis. Moreover, it is now accepted that OSAHS is correlated with painful bladder syndrome (interstitial cystitis) and the relationship between endometriosis and a decrease in sleep quality as well as chronic fatigue syndrome has also been demonstrated.
Finally, the benefit of Continuous Positive Airway Pressure (CPAP) treatment on endothelial dysfunction has been demonstrated and, empirically, in cooperation with the investigational site's pain unit, a symptomatic improvement in women with endometriosis and OSAHS after initiation of CPAP treatment was observed.
The study aims at exploring the occurrence of OSAHS in patients with endometriosis followed in the site's dedicated pain unit and the impact of OSAHS treatment when it exists, on the symptoms of endometriosis and quality of life.
OSAHS diagnosis will be made according to standard of care practice in the investigation site. Patients with confirmed diagnosis of OSAHS will be treated according to national recommendations for this disease (CPAP or alternative treatments) and will complete questionnaires at 3, 6 and 12 months after start of OSAHS treatment to assess the impact of OSAHS treatment on various endometriosis-related symptoms.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Patients with confirmed Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) diagnosis Patients from site's pain unit with confirmed OSAHS diagnosis. OSAHS diagnosis will be made according to standard of care practice in the investigation site, through polysomnography and Epworth Sleepiness Scale (ESS). |
Other: questionnaires completion
Patients will complete the following questionnaires at 3, 6 and 12 months after start of the treatment for Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS):
Pain-related questionnaire
Endometriosis-specific questionnaire
Hospital Anxiety and Depression scale
Questionnaire McGill on Quality Of Life
Insomnia-related questionnaire

Outcome Measures
Primary Outcome Measures
- the number of patients suffering from endometriosis, followed in the site's dedicated pain unit, and who are diagnosed with Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) [12 months]
The diagnosis of OSAHS will be performed as per standard of care procedures (medical assessment and polysomnography).Patients with confirmed OSAHS diagnosis will be accounted for the study as positive (Yes) for the primary endpoint. Patients who are not diagnosed with OSAHS will be accounted for the study as Negative (No) for the primary endpoint and will discontinue from the study without being followed up to 12 months in the study
Secondary Outcome Measures
- Assessment of the impact of Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) treatment on endometriosis-associated pain [3, 6 and 12 months]
Patients with confirmed OSAHS diagnosis will complete Pain-related questionnaire at 3, 6 and 12 months after start of OSAHS treatment
- Assessment of the impact of Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) treatment on endometriosis-specific symptoms [3, 6 and 12 months]
Patients with confirmed OSAHS diagnosis will complete Endometriosis-specific questionnaire at 3, 6 and 12 months after start of OSAHS treatment
- Assessment of the impact of Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) treatment on anxiety and depression [3, 6 and 12 months]
Patients with confirmed OSAHS diagnosis will complete Hospital Anxiety and Depression scale at 3, 6 and 12 months after start of OSAHS treatment
- Assessment of the impact of Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) treatment on quality of life [3, 6 and 12 months]
Patients with confirmed OSAHS diagnosis will complete the Questionnaire McGill on Quality Of Life at 3, 6 and 12 months after start of OSAHS treatment
- Exploration of the correlation between answers to the Insomnia-related questionnaire and the sleep disorders objectified by the nocturnal recordings. [3, 6 and 12 months]
Patients with confirmed OSAHS diagnosis will complete Insomnia Severity Index questionnaire at 3, 6 and 12 months after start of OSAHS treatment
- Exploration of the relationship between cardiological symptoms (palpitations, malaise, chest pain) and the existence of Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) [12 months]
Cardiological symptoms occurrence (palpitations, malaise, chest pain) will be assessed from baseline up to the end of study.
