About this study

Official title: Pilot Epidemiological Study to Determine the Prevalence of Pharyngolaryngeal Reflux in Patients Treated for Obstructive Sleep Apnea Syndrome

The aim of the study is to find, using validated and efficient tools, a laryngopharyngeal reflux in patients receiving polysomnography for suspected obstructive sleep apnea syndrome.

It is proposed to carry out simultaneously, at the Sleep Center of the Polyclinique of Poitiers (CSPP), a polysomnography, a 24-hour Restech pharyngeal pH-metry (day and night), a Peptest (in the evening and in the morning of the polysomnography), with the RSS-12 questionnaire and the RSA score.

Being tested
Polysomnography, Pharyngeal ph-metry Restech, Peptest, Questionnaire RSS-12, Reflux Sign Assessment
Medical subject headings
Sleep Apnea, Obstructive, Laryngopharyngeal Reflux

What participants receive

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

  • PolysomnographyDiagnostic test

    A polysmnography is planned for every patients in order to evaluate the Apnea-Hypopnea Index (AHI).

  • Pharyngeal ph-metry RestechDiagnostic test

    Pharyngeal ph-metry Restech over 24 hours (night and day)

  • PeptestProcedure or surgery

    Saliva sample to look for an association between pharyngolaryngeal reflux and obstructive sleep apnea syndrome

  • Questionnaire RSS-12Behavioural

    Questionnaire with 12 items about quality of life. Score between 0 and 5.

  • Reflux Sign AssessmentProcedure or surgery

    RSA score about anatomy and morphology of the mouth

What is being measured

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

  1. Proportion of patients with Obstructive Sleep Apnea Syndrome diagnosed with pharyngolaryngeal reflux.

    the diagnosis of OSA is posed by the PSG as soon as the AHI is ≥ 15 / h

    Measured: 3 months

Secondary outcomes (3)
  1. RSS-12 score

    Positive (>11)

    Measured: 3 months

  2. RSA score

    Positive if > 14

    Measured: 3 months

  3. Peptest

    Positive if > 75 ng / mL

    Measured: 3 months
