Trial summary

The purpose of this study is to help us understand how HIV and/or Anti-Retroviral Therapy (ART) may predispose individuals to Obstructive Sleep Apnea (OSA). The traditional risk factors for OSA are weight and age. However, people living with HIV on ART seem to have OSA even when they are thin and young. Read more about this study

About this study

The purpose of this study is to help us understand how HIV and/or Anti-Retroviral Therapy (ART) may predispose individuals to Obstructive Sleep Apnea (OSA). The traditional risk factors for OSA are weight and age. However, people living with HIV on ART seem to have OSA even when they are thin and young. The study involves a detailed physiological sleep study and an MRI of the head and neck to understand the underlying cause of OSA in those with and without HIV.

Read the detailed description

Participants who have sleep apnea and are using positive airway pressure (PAP) with and without HIV will be enrolled if they otherwise meet all the inclusion criteria, and none of the exclusion criteria.

Subjects will undergo two overnight sleep studies (polysomnograms, PSGs) and a MRI scan of the upper airway. The first sleep study will evaluate the severity of sleep disordered breathing and will be identical to a clinical PSG. The second sleep study will measure the physiological traits most important for OSA, such as upper airway anatomy, control of breathing, sleep stability, and upper airway muscle activation. These measurements are performed while subjects sleep using PAP, but the PAP level is adjusted during the night, and the subject's response is measured. The MRI scan will be of the head and neck and will occur during the evening time. Subjects will be encouraged to sleep during this portion of the study, as well.

What participants receive

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

Study groups in NCT03064204
Study groupRoleWhat they receive
OSA+CPAP+HIV+Individuals (40 years or older) diagnosed with OSA and using CPAP, also with HIV treated to viral suppression.
OSA+CPAP+HIV-Individuals (40 years or older) diagnosed with OSA and using CPAP.

What is being measured

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

  1. Upper airway collapsibility (Vpassive)

    Upper airway collapsibility, as assessed by rapid withdrawal of PAP

    Measured: Night 2 (Visit 2 - to occur within 6 weeks of enrollment)

Secondary outcomes (2)
  1. Upper airway muscle responsiveness

    As assessed by rapid withdrawal of PAP

    Measured: Night 2 (Visit 2 - to occur within 6 weeks of enrollment)

  2. Pharyngeal fat pad thickness

    As measured by MRI of the head and neck

    Measured: MRI study (Visit 3 - to occur within 6 weeks of enrollment)

Questions about this trial

What is this clinical trial studying?

An observational study of Obstructive Sleep Apnea and HIV/AIDS, run by University of California, San Diego at 1 site in United States.

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 3 inclusion and 7 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 18 Feb 2022. 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 United States. 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?

Upper airway collapsibility (Vpassive) (time frame: Night 2 (Visit 2 - to occur within 6 weeks of enrollment)). 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 NCT03064204, which also lists 2 linked publications.

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 18 Feb 2022.
