Brief Summary
Polycystic ovary syndrome (PCOS) is one of the most common disease caused by hormonal imbalance and is also associated with overweight and obesity. It affects 5-10% of adolescent girls and women capable of having children. Polycystic ovary syndrome is associated with missed menstrual periods, hormonal imbalance, being overweight, and with a form of diabetes. Girls with polycystic ovary syndrome may have a breathing problem known as "sleep apnea." Sleep apnea may cause a person to stop breathing for short periods of time while sleeping. People with polycystic ovary syndrome are thirty times more likely to develop sleep apnea than those who do not have PCOS. If sleep apnea is not treated, it may lead to daytime sleepiness, poor school performance, high blood pressure, heart disease and diabetes. The purpose of this study is to understand how insulin function is affected in presence of sleep apnea in girls with polycystic ovary syndrome between 13-21 years of age as compared to girls with PCOS without sleep apnea. Insulin is one of the hormones made in your body to convert food into energy. In people with increase weight body cannot use insulin properly. The investigators also want to see if insulin action is also affected by sleep apnea.

Outcome Measures
Primary Outcomes (1)
The purpose of this study is to understand how insulin function is affected and how endothelial function as a surrogate marker for cardiovascular risk is affected in presence of sleep apnea as compared to girls (13-21 yrs) with PCOS without sleep apnea
Obese adolescents with PCOS will be assessed for presence or absence of Obstructive Sleep Apnea (OSA) at baseline. Obese PCOS with OSA will be compared with obese PCOS with out OSA for difference in Glucose Infusion Rate (GIR) as a measure of insulin resistance and for Reactive Hyperemia Peripheral Arterial Tonometry (RHPAT) score
baseline to two years
Secondary Outcomes (1)
We also want to see if there is any change in the levels of adipocytokines (Leptin, adiponectin, C Reactive Protein (CRP), Tumor Necrosis Factor (TNF) alpha, Free fatty acids) because of sleep apnea in obese PCOS adolescents.
baseline to two years
Other Outcomes (1)
The purpose of this study is to to determine the role that PCOS plays in insulin resistance in non-obese adolescents by comparing insulin resistance in adolescent girls ages 13-21 with lean PCOS to normal weight adolescents ages 18-21 without PCOS.
baseline to two years
Study Arms (5)
Obese PCOS and sleep apnea
BMI \>95%ile AND Polysomnography with AHI \>2.5 Will initiate Nasal Continuous positive airway pressure (CPAP)
Obese PCOS without sleep apnea
BMI \>95%ile AND Polysomnography with AHI \<2.5
Normal weight Controls
BMI \<85%ile AND regular menses
Lean PCOS and sleep apnea
BMI \<85%ile AND Polysomnography with AHI \>2.5 Will initiate Nasal Continuous positive airway pressure (CPAP)
Lean PCOS without sleep apnea
BMI \<85%ile AND Polysomnography with AHI \<2.5
Interventions
We will initiate treatment of OSA with CPAP for 3 months in PCOS adolescents with moderate to severe OSA. Compliance will be defined as the average number of hours for which CPAP was used per night over the 12-wk treatment period. Adherence with CPAP will be defined as CPAP use ≥4 hours daily. The primary outcome variable will be insulin sensitivity measured as change in GIR. Changes in cardio metabolic variables after CPAP treatment will be expressed as a percentage of the corresponding baseline values.
