Inflammatory Markers in Obstructive Sleep Apnea (OSA) Patients.

The aim of our study was to assess the levels of inflammatory biomarkers in a large sample of OSA patients and to investigate any correlation between these markers with clinical and polysomnographic (PSG) parameters. Subjects undergone a PSG for OSA diagnosis were recruited. Patients with known comorbidities were excluded from the study. Included patients were grouped according to apnea-hypopnea index (AHI) as mild, moderate and severe. Patients with AHI \< 5 served as control group. Demographic, PSG data, serum levels of hs-C-reactive protein (hs-CRP), fibrinogen, erythrocyte sedimentation rate (ESR) and Uric Acid (UA) were measured and compared between groups.
