Abstract

Background. Obstructive Sleep Apnea Syndrome OSAS is associated with inflammation, but obesity may be a confounding factor. Thus, the aim of this study was to explore differences in serum levels of inflammation markers between obese individuals with or without OSAS. Methods. Healthy individuals from an outpatient obesity clinic were examined by polysomnography and blood analysis, for measurement of TNF- , IL-6, CRP, and fibrinogen levels. According to Apnea-Hypopnea Index AHI, participants were divided into two BMI-matched groups: controls AHI < 15-h, and OSAS patients AHI   15-h, . Results. OSAS patients had significantly higher TNF- levels while no other difference in the examined inflammation markers was recorded between groups. Overall, TNF- levels were correlated with neck circumference , AHI , and Oxygen Desaturation Index . Conclusions. Obese OSAS patients have elevated TNF- levels compared to BMI-matched controls, suggesting a role of OSAS in promoting inflammation, possibly mediated by TNF-a.
