Active clinical trials for "Sleep Apnea Syndromes"

CPAP is the most effective treatment of obstructive sleep apnea. Oro-nasal masks may be used in case of mouth leaks but these are associated with higher positive pressure needs and lower compliance to treatment. The present investigation evaluates if CPAP compliance would increase when an oral appliance is used in combination with a nasal mask compared to the use of an oro-nasal mask. Eligible patients are those demonstrating a low compliance when using an oro-nasal mask during CPAP therapy. Patients will be treated with automatic CPAP with one of the above-detailed interfaces for 4 weeks and data will be extracted from the machine report in each condition.

The aim of this study is to determine the usefulness of a telemedicine system for the follow-up of OSA patients with a high cardiovascular risk. Our hypothesis is that the telemedicine system will enhance compliance and thus reduce self-measured blood pressure.

Hypothesis: Portable sleep testing of hospitalized medical inpatients suspected of having OSA is accurate in determining the need for positive airway pressure (PAP) therapy when compared to outpatient laboratory-based polysomnography. Hospitalized medical inpatients referred for suspected OSA will be tested with a portable sleep apnea testing device during hospitalization. These patients will then undergo an outpatient laboratory-based attended polysomnography after hospital discharge. Results of the inpatient portable sleep apnea test will be compared to the outpatient laboratory-based polysomnography in terms of diagnostic accuracy.

Obstructive sleep apnea (OSA) is independently associated with important heart remodeling that further contributes to overt heart failure. Recent evidences using echocardiogram suggested that continuous positive airway pressure (CPAP) has beneficial effects mainly on left ventricle parameters. However, the evidences regarding the right ventricle are scanty. In addition, no previous studies evaluated morphological and functional characteristics in OSA by magnetic resonance imaging (MRI) as well as the impact of CPAP.

This is a research study of the effect of treating laryngomalacia (floppiness of tissue on top of the voice box that can possibly block breathing) found in association with obstructive sleep apnea (blockage of breathing while sleeping). The purpose of this study is to determine which is the best treatment for children with obstructive sleep apnea and laryngomalacia: adenotonsillectomy alone or adenotonsillectomy with laser supraglottoplasty (removal of tissue on top of the voice box to open the airway).

Polycystic ovary syndrome (PCOS) affects 5-10% of women in the United States. Its onset is usually at the time of puberty with manifestations of menstrual irregularity, hirsutism, and obesity. Women with PCOS suffer at an early stage of adulthood from all of the components of the metabolic syndrome, a syndrome that typically has its peak in mid-life in other subject populations. Women with PCOS are more insulin resistant than weight-matched control women and have exceptionally high rates of early-onset impaired glucose tolerance and type 2 diabetes, as well as a substantially elevated risk for hypertension, dyslipidemia, coronary, and other vascular diseases. While recent evidence indicates that the prevalence of sleep-disordered breathing (SDB) is 30-40 fold higher in PCOS than in weight-matched control women, the possible role of SDB in causing the increased metabolic and cardiovascular risks of PCOS has not been evaluated. The overall objective of the proposed study is to analyze the direction of causality between sleep disturbances and markers of the metabolic syndrome in PCOS.

Adenotonsillectomy is one of the most common surgical procedures performed in the pediatric population in the United States. It is generally a well-tolerated procedure with post-operative bleeding risk ranging from 3-5% in children. Post-operative pain following adenotonsillectomy has significant morbidity and may result in prolonged hospital stay or re-admission to the hospital. Post-operative analgesia is most commonly managed with narcotic-containing pain medication. In recent years however, there is evidence that some patients may manifest increased sensitivity to narcotics, resulting in life-threatening respiratory compromise. Though there is a theoretical risk that nonsteroidal anti-inflammatory drugs (NSAIDs) increase bleeding time by disrupting platelet aggregation, evidence of detrimental effects (i.e. increased risk of postoperative bleeding) remains inconclusive for these generally well-tolerated medications. The goal of this study is to determine the incidence of post-operative bleeding and to determine the efficacy of NSAIDs in the management of post-operative pain following pediatric adenotonsillectomy, versus more commonly used narcotic pain medication. The study design will be an initial retrospective study to collect pilot data on the incidence of postoperative hemorrhage and indicators of adequate/inadequate pain control in children age 4 to 17 undergoing adenotonsillectomy. This will be followed by a prospective, randomized, single-blind controlled study in which orally-administered ibuprofen (test intervention) is compared to acetaminophen-hydrocodone (control intervention) in the postoperative period following adenotonsillectomy.

Evaluation of the add-on effect on endothelial dysfunction of treatment of periodontitis in patients with chronic periodontitis and severe obstructive sleep apnea treated by CPAP. Patients with and without chronic periodontitis will be treated by CPAP for 20 weeks. At V2 (10 weeks), endothelial dysfunction will be assessed by the Reactive Hyperemia- Peripheral Artery Tone index. The endothelial dysfunction of the patients will be also assessed at V3 (20 weeks) after periodontitis treatment for the group of patients with chronic periodontitis.

The aim of this randomized control study is to evaluate the effect of tonsillectomy with or without uvulopalatoplasty in treating adults with moderate to severe sleep apnea.

This is a multicenter, randomized, parallel-group, open label study of the efficacy of AVAPS-AE to prevent re-hospitalization in hospitalized patients with comorbid Chronic Obstructive Pulmonary Disease (COPD).
