Trial summary

Sleep apnea is a common disease in the general population and more particularly in elderly subjects in whom prevalence can reach 30 % after 70 years old. In adults (<55 years old) cardiovascular consequences are well known and make sleep apnea treatment necessary. Read more about this study

About this study

Sleep apnea is a common disease in the general population and more particularly in elderly subjects in whom prevalence can reach 30 % after 70 years old. In adults (<55 years old) cardiovascular consequences are well known and make sleep apnea treatment necessary. However elderly (>70 years old) apneic subjects are less symptomatic in terms of sleepiness, they usually present a lower index of respiratory events and cardiovascular consequences in this population are still discussed, driving some authors to consider sleep apnea in the elderly as a specific disease and making the need for a treatment questionable.

In this study the investigators will focus on the comparison between adult and elderly apneic subjects in terms of cognitive and cardiovascular consequences. Adult apneic patients suffer from a decrease of cognitive performance as well as grey matter local atrophy, particularly in the hippocampus and in the frontal lobes. According to fewer studies, white matter can also be affected by a demyelinisation process. These structural modifications are sometimes associated with disorders of executive and memory functions. In the elderly, no clear association can be drawn between cognitive decline and sleep apnea. Moreover, to our knowledge, the cerebral state of elderly symptomatic apneic subjects has mostly not be investigated.

Read the detailed description

The goal of this project is to evaluate the impact of sleep apnea on the brain according to age. Our hypothesis is that adult apneic subjects would present local cerebral modification in the areas implied in cognition and memory, such as the hippocampus or the frontal areas, whereas elderly patients would present focal affects related to a deficit in the ventilatory and autonomic control without any major cognitive consequences.

Understanding the consequences of sleep apnea according to age could permit to refine the indications of sleep apnea treatment, mainly in elderly patients.

What participants receive

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

  • Magnetic resonance imaging (MRI)Device

    The acquisition of the image will last 45 minutes with 6 sequences.

    • Before any examination, the manipulator will check the absence of contraindication to MRI.
    • During the fifth sequence, Gadolinium (Gadovist®) will be injected intravenously to the concentration 0.1 mmol / kg. For this, a venous catheter will be placed before the first sequence and then removed after the examination. This injection will be carried out according to the usual practice of MRI.
    • Throughout the examination, a physician will always be present.
  • Cognitive assessmentBehavioural

    This cognitive assessment will include the following executive tests :

    • test of Stroop
    • left Trail Making Test A and B
    • verbal fluence test
    • test of memory of figures direct and inverse in order
    • completion of matrices
    • Paced Auditory Serial Addition Test (PASAT)

What is being measured

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

  1. Level of grey of each of the voxels of the cerebral grey matter

    We will use a technique widely used in neuroimage : the voxel-based morphometry (VBM) which allows a precise comparison by assessing local subtle differences at a voxel level (a voxel being a 3D-pixel).

    Measured: During the MRI procedure

Secondary outcomes (3)
  1. Level of grey of each of the voxels of the cerebral white matter

    We will use a technique widely used in neuroimage : the voxel-based morphometry (VBM) which allows a precise comparison by assessing local subtle differences at a voxel level (a voxel being a 3D-pixel).

    Measured: During the MRI procedure

  2. Cognitive score

    It is the sum of the scores of the following tests :

    • test of Stroop
    • left Trail Making Test A and B
    • verbal fluence test
    • test of memory of figures direct and inverse in order
    • completion of matrices
    • Paced Auditory Serial Addition Test (PASAT)

    Measured: At the inclusion

  3. Dosage of the markers of the inflammation

    The blood markers of the inflammation are : C reactive protein (CRP US), Il1β, Il6, Il10, Tumor Necrosis Factor(TNFα) et Mitochondrial Pyruvate Carrier 1 (MPC1)

    Measured: At the inclusion

Questions about this trial

What is this clinical trial studying?

An observational study of Obstructive Sleep Apnea (SAOS) and Aging, run by Centre Hospitalier Universitaire de Saint Etienne 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 6 inclusion and 8 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 13 Mar 2024. 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 was stopped early (reason given: change of Magnetic resonance imaging (MRI) research). 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?

Level of grey of each of the voxels of the cerebral grey matter (time frame: During the MRI procedure). 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 13 Mar 2024.
