Overview

Brief Summary

Recent years have witnessed major advances in the understanding of the hormonal, metabolic, and biochemical changes that occur in obstructive sleep apnea (OSA). This project evaluates the biomarkers that measure the most significant health impacts of this disorder and creates a specimen bank that will facilitate evaluations of additional biomarkers in the future.

Detailed Description

This is a case-control study to examine the relationship between obstructive sleep apnea (OSA) and elevated levels of leptin, homocysteine, and C-reactive protein (CRP) in moderate or severe OSA and control patients. This is followed by a prospective cohort study to examine the relationship between surgical treatment of moderate or severe OSA and serum levels of these biomarkers. The short-term goals of this study consider the abnormalities in biomarker levels associated with OSA and specific aspects of the disorder as well as whether the changes seen after surgical treatment of OSA mirror those demonstrated after efficacious non-surgical treatment. The long term goals are in two areas: 1) the development of measures to determine which patients require treatment for sleep-disordered breathing and to monitor the effectiveness of therapy, and 2) a deeper understanding of the connection between OSA and its adverse health consequences.

Eligibility Criteria

Inclusion Criteria

•OSA group is adults with moderate or severe OSA (apnea \>= 15 based on preoperative sleep study) undergoing surgical treatment. Assessment is done prior to surgery.
•Control group is overweight (body mass \>25) adults without OSA (apnea-hypopnea index \<5 based on sleep study) or other sleep disorders. Assessment is prior to treatment.
