Epigenetics Modifications in Obstructive Sleep Apnea (EPIOSA)
Changes in epigenetic regulation of genes involved in systemic inflammation and metabolic dysfunction in OSA are linked with accelerated cardiovascular morbidity.

Obstructive slep apnea patients
Patients with OSA
Subjects without OSA
Design. EPIOSA is a 5-yr non-interventional longitudinal prospective study being conducted at the Sleep Clinic of the Hospital Miguel Servet, a large teaching hospital in Zaragoza (Spain). Following a baseline visit, subjects are to be followed-up at 3 months, and then every year.
Subject participation. The investigators will enroll a total 300 consecutive OSA male patients aged 20-60 yrs, with baseline apnea-hypopnea index ≥ 5 events per hour of sleep (AHI). In addition, 50 control subjects (AHI < 5) aged 20-60 yrs and matched by body mass index (BMI) are also to be recruited. Exclusion criteria will include any comorbid condition including alcohol and tobacco use.
Measurements: Routine clinical assessment, full sleep study, bilateral carotid ultrasonography, biochemistry, circulating inflammatory cytokines, T cell subsets and epigenetics studies at baseline and every year until at least 5 years of follow-up.
