Brief Summary

Obstructive sleep apnea (OSA) is a breathing disorder that is characterized by episodes of complete or partial cessation of respiration during sleep, associated with upper airway collapse, oxygen desaturation and sleep fragmentation. OSA is a condition frequently implicated in cognitive disturbances, as well as associated with health conditions such as hypertension, metabolic disturbances and heightened risk of heart disease, stroke and mortality. These conditions are also increased in persons living with HIV. Individuals suffering from OSA report an increase in daytime sleepiness, mood changes and decline in quality of life.OSA also portends economic and societal impact through lost productivity at work and motor vehicle accidents. The presence of OSA is therefore important to detect in those living with HIV as it is potentially treatable contributors to cognitive disturbances in HIV. Continuous Positive Airway Pressure (CPAP) is the recommended treatment of choice for OSA. CPAP has established efficacy in improving cognition (executive function, long-term verbal and visual memory, attention/vigilance and global cognitive functioning). Although CPAP has been associated with improvements in cognitive functioning in the general population, its effectiveness in improving cognition in HIV+ individuals has never been previously tested. Given that cognitive disturbances in this population are multi-factorial, determining whether treatment of OSA in this population improves cognition is key in improving the clinical management of HIV+ individuals, both for its negative impact on cognition, but also more generally for their health.

Outcome Measures

Primary Outcomes (1)

  • Changes in Cognitive Performance measure (B-CAM)

    The research team will be looking at changes on the B-CAM (brief cognitive ability measure) pre- and post-intervention

    Up to 5 months before the beginning of the intervention and up to 1 month after the end of the intervention.

Secondary Outcomes (2)

  • Changes Self-reported cognitive difficulties (C3Q)

    One week before the beginning of the intervention and up to 4 weeks after the end of the intervention

  • Adherence to the CPAP treatment

    During the treatment (between 4 to 7 months)

Study Arms (3)

CPAP intervention

EXPERIMENTAL

Over the course of 4-7 months, participants will have to wear the CPAP every night, at least 4 hours per night.

Behavioral: CPAP intervention

Control 1

NO INTERVENTION

Eligible participants who declined to participate in the study. Their main study visit data will be used to compare with the intervention group.

Control 2

NO INTERVENTION

Eligible participants who were not approached, hence not given the opportunity to accept or decline. Their main study visit data will be used to compare with the intervention group.

Interventions

Participants who agree to participate will be evaluated by a sleep specialist who will confirm eligibility for CPAP treatment.Eligible participants will be referred to VitalAire for initiation of treatment following a standard protocol for CPAP use at home. CPAP treatment will continue until the next visit for the main study, between 4-7 months, based on the timing of the evaluations, after which the study will end.
