Active clinical trials for "Apnea"

Patients with Obstructive Sleep Apnea Syndrome (OSAS) will evidence higher levels of salivary cortisol and alpha-amylase levels prior to use of placebo and continuous positive airway pressure (CPAP) and will evidence a decrease in these levels after consistent use of continuous positive airway pressure (CPAP) therapy as compared to placebo. Their level of sleepiness will also decrease with the use of CPAP therapy and will correlate with the levels of salivary cortisol and alpha-amylase in relation to their subjective sleepiness scale, Psychomotor Vigilance Test (PVT), and pupillometry.

Objective: to evaluate the effects of a speech therapy exercises program in the treatment of Obstructive Sleep Apna Syndrome (OSAS) patients based on the clinical and polysomnography (PSG) parameters. Methods: 80 patients with OSAS will be evaluated: men, 25-65 years old, body mass index < 35 kg/m2 and scores of Epworth Sleepiness Scale > 9. Patients will be divided into four groups: I: 20 patients with OSAS underwent speech therapy; II: 20 patients with OSAS underwent placebo therapy of Speech Therapy; III: 20 patients starting treatment with CPAP underwent speech therapy; IV: 20 patients starting treatment with CPAP without speech therapy or placebo. The speech therapy include isometric and isotonic exercises to improve posture, mobility and muscle tone of the soft palate, pharyngeal constrictor muscles, tip and base of tongue, cheeks and lips. Placebo therapy includes relaxation exercises and stretching neck, without therapeutic purpose. Both therapies are applied for three months, three times a day, lasting 20 minutes each session. During the treatment, the subjects will be monitored in weekly meetings, for orientation and description of the exercises and return of the fulfilled exercises diary. The subjects will also be followed at the CPAP clinic in returns after one week, a month and at the end of the study. Conduct assessments before and after treatment and after twenty one days washout, including: assessing the upper airway, anthropometric investigation of the facial skeleton and speech of Orofacial, questionnaires (Epworth Sleepiness Scale, FOSQ, General Segment and use of CPAP, WHOQOL-BREF, snoring), Psychomotor Vigilance Test and PSG.

This study will evaluate the effect and safety of adalimumab in approximately 20 subjects with mild to moderate psoriasis and sleep apnea and will be conducted in one treatment center located in Montreal. Patients with psoriasis often have additional disorders such as obesity. Obese patients are more at risk of developing obstructive sleep apnea. This is believed to be caused by both the collapse of upper airways and inflammation (swelling). Adalimumab, a drug currently approved by Health Canada for the treatment of psoriasis, blocks tumor necrosis factor-alpha (TNF-alpha). This chemical is present at higher levels in patients with sleep apnea. It is believed that adalimumab could improve obstructive sleep apnea by lowering the levels of TNF-alpha.

Randomised, placebo-controlled trial of continuous positive airway pressure therapy (CPAP) versus Provent® and Placebo-Provent® to define the effects of Provent® on the severity of obstructive sleep apnea, daytime symptoms as well as on measures of cardiovascular risk.

The aim is to evaluate the effect of treatment with Continuous Positive Airway Pressure (CPAP) device on clinic and ambulatory blood pressures (BP) of 200 resistant hypertensive patients with moderate-severe obstructive sleep apnea syndrome (OSAS).

Sleep Apnea Hypopnea Syndrome (OSAHS), is common in patients with OHS, compared to single Obesity Hypoventilation Syndrome (OHS) or OSAHS ,patients with both of them are more susceptible to have serious hypoxia and carbon dioxide retention during sleep, and much more likely to result in pulmonary hypertension and cor-pulmonale. At present, the most widely and valid method for these patients is the Bilevel Positive Airway Pressure (BiPAP) ventilation, while, recently, the investigators discovered a completely novel device, namely auto-trilevel Ventilator. In contrast to the traditional therapy, auto-trilevel Ventilator has a more flexible expiratory positive airway pressure (EPAP), with which it can removing residual obstructive sleep apnea hypopnea events and correcting hypercapnia without contradiction. Treated with auto-trilevel ventilator may delay the progression of disease and improve life quality. The overall purpose of this study is to determine the curative effects of auto-trilevel ventilators on patients with OHS and OSAHS.

In children, enlarged adenoids and/or tonsils are the most common cause of obstructive sleep apnea (OSA), which is temporary blockage of breathing during sleep. Surgery to remove the tonsils and adenoids is the first-line treatment for disorder, and has been shown to cure the majority of children. However, for children with only a mild degree of OSA and few symptoms, surgery is less clear-cut, since two-thirds of these children do not develop worsening disease. Research shows that some children with mild OSA and behavior problems are helped by removing the tonsils and adenoids. In children with all degrees of OSA, surgery has improved scores on tests that measure quality of life (QOL). The investigators hypothesize that children with mild OSA will demonstrate changes on QOL assessment following adenotonsillectomy. These findings may help to guide the surgeon in selecting the children with mild OSA who are more likely to benefit from surgery.

The purpose of this study is to evaluate the associations of circadian variations, sleep architecture, hypertension and prostanoids in the patients with sleep apnea. In addition, the patients introduced to continuous positive airway pressure(CPAP) treatment, the effects of CPAP are also evaluated.

This is a study of the safety and efficacy of MK-7288 for the treatment of excessive daytime sleepiness (EDS) in participants with obstructive sleep apnea (OSA)/hypopnea syndrome (HS) who are compliant with effective nasal continuous positive airway pressure (nCPAP) therapy. The goal of this study is to determine the effect of MK-7288 after single dose administration on promoting wakefulness as measured by sleep latency on Maintenance of Wakefulness Tests, and on driving performance as measured by standard deviation of lane position in simulated driving (country vigilance driving).

In children with mild apnea combined therapy with an inhaled nasal steroid and a medication that decreased nasal congestion (montelukast) was shown to be effective. We are testing to see if this combination works in adults with mild apnea as well.
