|Official Title:||Biomarkers in Obstructive Sleep Apnea Surgery|
- Leptin, homocysteine, and C-reactive protein levels. [ Time Frame: Before and after surgery ]
|Study Start Date:||June 2005|
|Study Completion Date:||June 2007|
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.
