Sleep Apnea, Obstructive

Study type: Interventional

Study phase: N/A

Overall status: Recruiting

Study design:

Allocation: Randomized

Intervention model: Parallel Assignment

Primary purpose: Treatment

Masking: Single (Participant)

Intervention:

Intervention type: Device
Intervention name: Continuous Positive Airway Pressure Device (CPAP)
Description: Metabolic studies will be performed before and after initiation of CPAP therapy, which is currently the first-line standard of care for treatment of patients with OSA, both with and without hypoxia.
Arm group label: CPAP Group

Intervention type: Other
Intervention name: Delayed Continuous Positive Airway Pressure Device (CPAP)
Description: Metabolic studies will be performed before and after the study period of 12 weeks. After 12 weeks, participants will immediate receive CPAP therapy, which is currently the first-line standard of care for treatment of patients with OSA, both with and without hypoxia.
Arm group label: Delayed CPAP Group

Summary: In this study, the researchers are trying to learn more about the relationship between Polycystic Ovary Syndrome and Obstructive Sleep Apnea (OSA). Obstructive Sleep Apnea is a sleep-related breathing disorder that involves a decrease or complete stop in airflow. The purpose of this study is to find out why some people with obstructive sleep apnea have higher levels of insulin resistance, and the investigators will study the role of hypoxia (low levels of oxygen in the blood at night) in insulin resistance and see if insulin resistance improves during your treatment with CPAP.

Detailed description: Today, approximately 5 million Americans of reproductive age have Polycystic Ovary Syndrome (PCOS). The personal and public health burden of PCOS is high. People with PCOS are at elevated risk of infertility, endometrial cancer, obesity, diabetes, dyslipidemia and nonalcoholic fatty liver disease (NAFLD). Moreover, there is a paucity of treatments that address the metabolic and reproductive concerns of this disorder. Obstructive sleep apnea (OSA) is a recognized co-morbidity of PCOS that may exacerbate both metabolic and reproductive aspects of PCOS. Thus, treating OSA represents a potentially attractive tool to improve outcomes in PCOS. Indeed, continuous positive airway pressure therapy (CPAP) is a relatively inexpensive treatment for OSA that is safe for use in women in the reproductive years, even when pregnant or trying to conceive. However, evidence regarding the impact of CPAP use in PCOS populations is lacking, and, currently, screening and treatment of OSA is only considered standard of care to treat symptoms of excessive sleepiness or hypertension. Because an estimated 15-45% of people with moderate/severe OSA do not have these symptoms, treatment is not considered standard of care for the majority of persons with OSA and PCOS. From another study looking at sleep and PCOS, we will identify 20 subjects with moderate-to-severe OSA without excessive daytime sleepiness who will enroll in a CPAP trial. These subjects will undergo intensive multi-tissue insulin resistance testing and will be assigned treatment with CPAP or delayed treatment after 12 weeks after which all measures will be re-assessed. Accordingly, this proposal will address an unanswered question: Does CPAP provide metabolic or reproductive benefits in PCOS? The results will also better define potential mechanistic pathways linking OSA to insulin resistance and will determine whether CPAP improves key outcomes.
