Active clinical trials for "Sleep Apnea Syndromes"

The purpose of this study is to evaluate the hypnotic efficacy of ezopiclone in subjects with mild to moderate OSAS.

Metabolic syndrome is a constellation of risk factors for cardiovascular disease. The prevalence of metabolic syndrome in persons with obstructive sleep apnea syndrome (OSAS) is known to be very high, about 70%. However, it is unclear whether this association is causal or not. Results of earlier studies have been conflicting. The investigators hypothesize that treatment with auto-titrating continuous positive airway pressure (auto-CPAP) for a duration of 3 months improves the metabolic syndrome in subjects with OSAS.

The primary objective of this study is to observe if Sibutramine is effective in improving the symptoms and signs of sleep apnea in obese patients. The secondary objectives are to document the effects of Sibutramine on heart rate variability and 24-h arterial pressure values. We hypothesized that sibutramine will improve sleep disordered breathing, cardiac autonomic function and systemic blood pressure in obese patients with obstructive sleep apnea (OSA).

C-reactive protein (CRP) is directly implicated in atherogenesis and associated cardiovascular morbidity in patients with obstructive sleep apnea (OSA). Effective Continuous Positive Airway Pressure (CPAP) treatment has been shown to gradually decrease CRP levels and thus consequently improve disease-related cardiovascular morbidity. However, the influence of gender on the CRP evolution pattern has never been assessed before. The aim of our study was to investigate possible gender differences in CRP evolution in OSA patients 3 and 6 months after the start of effective CPAP treatment.

Objective of the study: To determine whether Perioperative Auto-CPAP treatment prevent postoperative worsening of OSA and improve nocturnal oxygen saturation in surgical patients with moderate and severe OSA.

The purpose of this study is to determine the effects of the anticholinesterase drug donepezil on sleep in Alzheimer disease patients. Sleep structure and respiratory parameters will be analyzed by polysomnography.

Multicenter randomized double blind study versus placebo during 12 weeks with at first, an escalating dose period followed by stable dose period at the selected dose. This double-blind period can be followed by a 9 months open-label period if the patient wishes to continue with the study product.

The purpose of this study is to assess the feasibility of conducting a comparative effectiveness study comparing a medical versus surgical approach to the initial management of obstructive sleep apnea (OSA) in the setting of obesity.

This study is being conducted to find out if the use of inhaled corticosteroids has an affect on upper airway (UAW) collapsibility and sleep apnea risk. An inhaled corticosteroid is a common asthma controller medication like Flovent. Sleep apnea or sleep deprived breathing (SDB) is when someone stops breathing for a short period of time during sleep. For some reason, people with asthma have more sleep apnea and upper airway (UAW) collapsibility (weakness) than the general population. There are many possible reasons for this and one might be related to the use of inhaled corticosteroids. The overall hypothesis of this study is to determine whether inhaled fluticasone propionate (FP) increases UAW collapsibility and to assess tongue (genioglossus muscle) dysfunction as a potential underlying mechanism.

Obstructive sleep apnea (OSA) is a serious sleep disorder in which a person's breathing is restricted during sleep. Obese individuals with OSA are at an increased risk of inflammation and heart conditions, but it is unknown whether this risk is related to the effects of OSA or obesity. This study will evaluate whether OSA or obesity plays the primary role in inflammation related to heart disease. The study will also determine the independent effects of OSA and obesity on insulin resistance and blood vessel function.
