Active clinical trials for "Sleep Apnea, Obstructive"

The purpose of this research study is to examine the effects of two commonly used anesthetic drugs, dexmedetomidine and propofol, have on the shape and muscle tone of the upper airway in children, adolescents, and young adults with a history of obstructive sleep apnea (OSA) having an MRI scan. The results of this study will help in making the best decisions regarding the anesthesia medications that are most appropriate for children, adolescents, and young adults with OSA during MRI studies.

Automatically titrating continuous positive airway pressure (APAP) and continuous positive airway pressure (CPAP) are considered first-line treatments for obstructive sleep apnea. There is a growing body of evidence that suggests that early patient education and intervention may improve adherence with positive airway pressure. The investigators plan a prospective, randomized trial to see if telemonitoring in the first several weeks of PAP therapy improves adherence following 3 months of treatment.

This trial is a 12 week, randomized, double-blind, placebo controlled, multicenter, 5-arm parallel group study of safety and efficacy of JZP-110 in the treatment of excessive sleepiness in adult subjects with OSA.

Obstructive sleep apnea (OSA) affects up to 1% of the general pediatric population and is associated with adverse behavior and quality of life, as well as long term cardiopulmonary system complications. Trisomy 21 (Down Syndrome) is the most common chromosomal disorder, with a incidence of approximately 1 per 660-800 births. Patients with Down Syndrome have a higher incidence of OSA than the general pediatric population, with rates of 30-60%, resulting in increased morbidity and decreased quality of life for affected individuals. In children, adenotonsillectomy (T&A) is often a contributing factor to OSA, and adenotonsillectomy is a first line treatment. Children with Down Syndrome often undergo T&A for obstructive sleep apnea, however 30-50% will have persistent obstructive sleep patterns requiring continuous positive pressure airway support (CPAP) or tracheotomy. Persistent obstruction is attributed to anatomic and physiologic differences in this population, including reduced muscular tone, macroglossia, maxillary hypoplasia, and lingual tonsil hypertrophy. This pilot study is designed to determine if the Inspire® Upper Airway Simulation System, Model 3024 IPG, and any subsequent iteration thereof that are approved under P130008 for the treatment of obstructive sleep apnea, which has already been approved for use in adults with OSA, can be safely implanted and used in adolescents and young adults with Down Syndrome.

The purpose of this study is to obtain additional safety and efficacy data on the use of Inspire® therapy for the treatment of subjects with moderate to severe Obstructive Sleep Apnea.

Obstructive Sleep Apnea (OSA) is a common condition that may induce hemodynamic and metabolic dysregulation. However, it is not clear if OSA is a mere epiphenomenon or contributes to increase the morbidity associated with metabolic syndrome. This study was designed to evaluate the impact of OSA treatment with CPAP in consecutive patients with metabolic syndrome.

Background: Patients with obstructive sleep apnea run an increased risk of cardiovascular disease including hypertension. Continuous positive airway pressure (CPAP) is the first line of treatment. However, many patients skip CPAP for some nights. Aims: The primary aim was to investigate the cardiovascular effects of short-term CPAP withdrawal for five nights because of obstructive sleep apnea. Design: Randomized, parallel controlled trial Inclusion criteria: 100 patients with successful CPAP treatment for moderate to severe obstructive sleep apnea. Exclusion criteria: Dementia, heart infarction within 3 months, apnea hypopnea index > 10 with CPAP treatment. Randomization: 50 patients are randomized to sleep 5 days without CPAP and 50 patients to continue with CPAP treatment during the trial. Primary outcomes: Arterial stiffness, 24-hour blood pressure. Secondary outcomes: Effects of gender on outcome. Effects on brain natriuretic peptide, apnea-hypopnea index, oxygen desaturation-index, urine-catecholamines, blood lipids, C-reactive protein, glucose metabolism (S-glc, HBA1c), insulin resistance, serum creatinine, hemoglobin, daytime sleepiness (ESS, KSS), lung function (FVC, FEV1), airway inflammation (exhaled NO) Procedures: Sleep apnea investigation while patients are treated with CPAP for one night. Urinary samplings during the same night. They are also investigated with 24 h blood pressure measurements. Blood samples are taking fasting in the morning followed by measuring the arterial stiffness (Vicorder, Skidmore Medical UK) including pulse wave analysis using sphygmomanometer (Omron Japan). The same investigations are done at follow-up 5 days later where half of the patients have continued using CPAP treatment and half of them has slept without CPAP.

The purpose of this study is to assess the safety and effectiveness of TranQuillTM Sling (a suture or thread used in surgery that is knotless) in snoreplasty (surgery procedure) for the treatment of snoring and mild OSA in adult subjects. The TranQuill Sling Snoreplasty (QSS) is a procedure where the suture will be inserted into the soft palate tissues for the treatment of snoring and/or mild obstructive sleep apnea. Soft palate tissues are tissues in the back of the roof of the mouth. The research results will be used to provide data on feasibility (strengths and weaknesses), safety, performance, and effectiveness data for the Surgical Specialties, Inc as a therapy for snoring and/or mild obstructive sleep apnea. The TranQuillTM Sling is approved by the U.S. Food and Drug Administration (FDA). The TranQuillTM Sling is used in all types of surgery that involved deep tissues in the body. The investigator in charge of the study is Dr. Boyd Gillespie. MUSC and Dr. Gillespie receive financial support from Surgical Specialties, Inc. to conduct the study. MUSC is the only place that this study will be conducted. For this research study the investigators plan to enroll a total of up to 20 subjects at the Medical University of South Carolina.

Prospective, multicenter, double-blind, phase II, randomized, dose-response study in 5 parallel groups (dose-range).

The present research intends to focus clinically on selecting the right type of patient for mandibular advancement devices (MAD) therapy using screening tools such as advanced imaging and computational methods based on CT-Scan images as well as drug-induced sleep nasendoscopy techniques with simulation of the mandibular repositioning. The core of the research project relies on known and established methods accepted in several neighboring fields, but aims at the transfer of this knowledge by integrating it into this new domain. Doing so, the proposed biomedical research is directed towards clinical applications that incorporate innovative developments on the level of the diagnosis and therapy of a specific disease, being obstructive sleep apnea syndrome (OSAS). Furthermore, this study aims at registering objective compliance during MAD therapy.
