Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective of this study is to evaluate the decrease of inflammation of adipose tissue in obese and non-obese patients having a sleep apnea syndrome and treated or not by continuous positive airway pressure (cPAP).

An interim analysis will be performed when 40 patients will be included.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Inflammation of adipose tissue will be evaluated by RT-PCR on mRNA of pro and anti-inflammatory cytokines (IL-1, IL-6, IL-4, IL-10, IL-12, RANTES, TNFa, leptin, adiponectin, CD68).
