Active clinical trials for "Sleep Apnea Syndromes"

The main diagnostic challenge in patients with OSA (obstructive sleep apnea) is to determine the location of obstruction of the upper airway during sleep. This is so, because the otorhinolaryngology examination, which states probable site of obstruction of upper airways, is performed in the awake status. Therefore, drug-induced sleep endoscopy (DISE) has been introduced in the diagnostic algorithm of OSA patients during the last decade. The advantage of DISE is, that the collapse of upper airways, which is not visible during the awake status can be observed and targeted therapy according to the location and degree of obstruction of the upper airway can be applied. As a result, higher treatment success in patients with OSA can be reached.

This study evaluates the effect of the use of mandibular advancement devices (MAD) on dental occlusion and masticatory function during the first two years of obstructive sleep apnea (OSA) treatment. 52 participants diagnosed with obstructive sleep apnea will be studied, 26 will be treated with MAD and 26 participants will be treated with continuous positive airway pressure (CPAP) as a control group. Participants will perform masticatory tests to assess masticatory performance in comminute and mixing capacity. Masticatory satisfaction perceived by the participants will be evaluated by questionnaires. Occlusal contact area and other occlusal characteristics will be assessed using occlusal silicone and T-Scan registrations and 3D digital models obtained with intraoral scan. Data collection will be performed before treatment with MAD or CPAP, and at 3, 6, 12, and 24 months from the start of treatment.

The investigators planned to investigate the effect of close monitoring on compliance and the factors affecting compliance among patients receiving PAP treatment due to OSA.This study was a single-center, prospective, randomized, controlled study approved by the hospital's ethics committee.One hundred twenty-eight patients were randomized as group one or two as group 1 is the study and group 2 is the control group. The first group was called by phone on the 15th day to ask if there were any complaints or problems with the device. Sequentially, they were called for controls at the end of the first, third, and sixth months. The second group was accepted as the control group, following our clinic's standard procedure in the first and sixth months. The patients who came to the control were asked if there were any problems with the device and any difficulties in use, and they were again informed about the devices and masks.

This is a prospective, interventional cohort study of drug-induced sleep endoscopy (DISE). The goal is to evaluate the upper airway in a cohort of patients with obstructive sleep apnea hypopnea syndrome (OSAHS) diagnosed in a prior polysomnography. This study correlates the sedation level measured by entropy during DISE using propofol via a TCI pump with the local obstruction patterns of the upper airway according to the VOTE classification. As OSAHS is a widespread disease and the DISE procedure has become a common tool for diagnosis and evaluation of further treatment, a growing number of research articles deal with this topic. These articles are available through pubmed.

The purpose of this study is to determine whether 3-week of SPA therapy improves sleep apnea in patients with chronic venous insufficiency and concomitant Obstructive Sleep Apnea Syndrome (OSAS).

This is a single center pilot study evaluating the immediate effects of low-dose acetazolamide on respiratory control in subjects with treatment emergent sleep disordered breathing. The purpose of this study is to assess the immediate effect one-time low-dose acetazolamide on sleep breathing in (Treatment Emergent Sleep Disordered Breathing) TE-CSA subjects compared to subjects' baseline evaluation without acetazolamide. Investigators will also try to determine the immediate effect of one-time low-dose acetazolamide on subjects' resting ventilation and ventilatory response slope compared to subjects' baseline evaluation without acetazolamide.

A prospective study measuring changes in upper airway anatomy, quality of life measures, and polysomnographic parameters using a functional dental appliance (Homeoblock)

A previous pilot study on the use of self neck grasp, ESAP (Easy Sleep Apnea Predictor), showed a positive maneuver (unable to wrap hands completely around neck) to be 100% predictive of sleep apnea in a sleep clinic population. The investigators now would like to compare ESAP to other tests used to diagnose and screen for Sleep Apnea in type 2 diabetics. The tests will included Home Sleep Testing, sleep questionnaires Berlin and STOP-BANG and polysomnogram (PSG). Patients with type 2 diabetes in the Bassett Endocrine Clinic who are scheduled for a routine evaluation will be recruited to undergo; a Home Sleep Test along with two sleep questionnaires PSG. The screen test wil be compared to the results of the gold standard diagnostic test the PSG for their predictive value os OSA in the type 2 diabetic population.

It is often clinically impossible to differentiate children with an isolated snoring from those with OSA. The diagnosis of OSA is currently based on nocturnal, laboratory-based polysomnography. This expensive examination is poorly accessible due to appointments delays at hospital. Our study is designed to compare the characteristics of a home polysomnography versus standard polysomnography for the diagnosis of pediatric OSA.
