NCT ID: NCT05164211 Withdrawn - Clinical trials for Obstructive Sleep Apnea Syndrome

Didgeridoo Treatment to Improve Pharyngeal Compliance in Obstructive Sleep Apnea-hypopnea Syndrome in Children

SASDICO
Start date: September 5, 2022
Phase: N/A
Study type: Interventional

The therapeutic management of Obstructive Sleep Apnoea Syndrome in children remains a debated subject, only otorhinolaryngology surgery (adenoidectomy) has been studied on a large scale. Pathophysiologically, increased pharyngeal collapsibility is a major endotype of the disease and the investigators have shown that this surgery can improve pharyngeal compliance. The development of approaches to treat pharyngeal hypotonia by maxillofacial rehabilitation supports the treatment of this endotype. A study in adults showed a benefit from playing the didgeridoo, a wind instrument, for 3 months, without pathophysiological explanation. The investigators hypothesise that playing this instrument improves pharyngeal compliance (re-education effect) in a similar way to the effect observed after otorhinolaryngology surgery. This proof-of-concept study aims to demonstrate the effect of didgeridoo in children without syndromic pathology with a formal otorhinolaryngology surgical indication resulting from tonsillar hypertrophy (Brodsky grades III and IV) and symptomatology suggestive of Obstructive Sleep Apnoea Syndrome (Pediatric Sleep Questionnaire score ≥ 0.33). The investigators will take advantage of the long delay in performing the adenoidectomy (~6 months) in their university hospital to evaluate, before the scheduled surgery, the effect of the didgeridoo used for three months.

Intestinal Dysbiosis During Obstructive Sleep Apnea Syndrome

DYNAMIC
Start date: November 23, 2021
Phase: N/A
Study type: Interventional

Obstructive Sleep Apnea Syndrome (OSA) is one of the most common chronic diseases and is associated with prognostic cardiovascular and metabolic co-morbidities. OSAS is the recurrence of complete (apnea) or partial (hypopnea) collapse of the upper airway during sleep resulting in sleep fragmentation and chronic intermittent hypoxia (ICH) which are the major determinants of cardiovascular and metabolic complications including type 2 diabetes, obesity and non-alcoholic fatty liver. These comorbidities are associated with a change in intestinal microbial ecology. In most cases, there is a reduction in bacterial genetic diversity and more or less specific signatures of cardiovascular and metabolic diseases, making it possible to envisage personalized and innovative therapeutic treatments. In animals exposed to intermittent hypoxia, there is local hypoxia that increases intestinal permeability, produces a reduction in microbiota diversity and favors microbial species that are at the origin of pro-inflammatory factors. Continuous Positive Airway Pressure (CPAP) is the standard treatment for OSA. Its effect on the intestinal microbiota has not yet been evaluated.

NCT ID: NCT04938128 Withdrawn - Clinical trials for Sleep Apnea, Obstructive

Effect of CPAP vs Control on Nocturnal Dipping in Normotensive Patients With Obstructive Sleep Apnea

Start date: April 12, 2021
Phase: N/A
Study type: Interventional

This is an open-label, parallel, prospective, randomised control trial evaluating the effect of Continuous Positive airway pressure (CPAP), the standard treatment for obstructive sleep apnea (OSA) versus control (diet and lifestyle advice) on dipping status and blood pressure parameters in 100 non-dipper normotensive patients with moderate to severe obstructive sleep apnea and without established cardiovascular or metabolic disease.

NCT ID: NCT04922112 Withdrawn - Clinical trials for Obstructive Sleep Apnea

Sleep Apnea in Head and Neck Cancer Patients at the University of Colorado

OSA-HN
Start date: April 20, 2021
Phase: N/A
Study type: Interventional

Obstructive sleep apnea (OSA) is increasingly recognized in patients with squamous cell carcinoma of the head and neck (SCCHN). The prevalence prior and after cancer therapy is not well understood. OSA is identified as a contributing factor for daytime somnolence and quality of life (QOL), yet treatment of OSA in the SCCHN population has not been studied. The investigators hope to identify the disease course of sleep apnea, risk factors for development, and impact on QOL with treatment of OSA in a population of patients with SCCHN.

NCT ID: NCT04630639 Withdrawn - Clinical trials for Sleep Apnea, Obstructive

Sparkle Respiratory Effort Validation

Start date: March 2021
Phase: N/A
Study type: Interventional

This study has been developed in order to demonstrate the validity of the Sparkle respiratory effort signal.

NCT ID: NCT04473534 Withdrawn - Clinical trials for Obstructive Sleep Apnea

Web Based CBT-I in Patients With OSA and Insomnia

Start date: March 10, 2021
Phase: N/A
Study type: Interventional

Obstructive sleep apnea (OSA) and insomnia often occur in the same patient. Recent studies have demonstrated the efficacy of cognitive behavioral therapy (CBT-I) in patients with insomnia and OSA. Our aim is to verify the efficacy of web based CBT-I in patients with OSA and insomnia and the effect of web based CBT-I on the acceptance and adherence to CPAP (Continuous Positive Airway Pressure) therapy.

NCT ID: NCT04205136 Withdrawn - Clinical trials for Obstructive Sleep Apnea

Spironolactone to Improve Apnea and Cardiovascular Markers in Obstructive Sleep Apnea Patients

Start date: March 2022
Phase: Phase 4
Study type: Interventional

The purpose of this study is to test whether Spironolactone can improve the severity of obstructive sleep apnea and improve cardiovascular biomarkers in people who are not regularly using their Positive Airway Pressure (PAP) therapy.

NCT ID: NCT04190498 Withdrawn - Clinical trials for Hepatocellular Carcinoma

Sleep Apnoea Syndrome and Hepatocellular Carcinoma

ECHAPS
Start date: January 21, 2020
Phase:
Study type: Observational

Obstructive sleep apnea (OSA), one of the most frequent respiratory diseases, could represent a major worsening factor in a non alcoholic steatohepatitis and neoplastic context. Our hypothesis is that OSA promotes the prevalence of HCC related to NASH. This national, multicenter study aims to compare the prevalence of OSA in a group of patient curatively resected for NASH-related HCC with a group of HCV-related HCC.

NCT ID: NCT04063436 Withdrawn - Clinical trials for Obstructive Sleep Apnea

Evaluation of a New Nasal Pillows Mask for the Treatment of Obstructive Sleep Apnea

Start date: September 23, 2019
Phase: N/A
Study type: Interventional

This clinical trial is designed to evaluate the performance, comfort, and usability of a new nasal pillows mask for the treatment of obstructive sleep apnea (OSA) in a home environment.

NCT ID: NCT04053153 Withdrawn - Sleep Apnea Clinical Trials

Effects of Upper Airway Muscle Training on Obstructive Sleep Apnea Severity

Start date: May 1, 2021
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate the effect of Asate Silent Sleep Training on obstructive sleep apnea (OSA) severity in patients with mild to moderate OSA. The Asate Silent Sleep Training is a muscle strengthening program that uses exercise equipment (a musical instrument that is based on the didgeridoo). The equipment is connected to an application, which provides instruction on how to perform the strengthening exercises, measures the sound produced by the musical instrument, which enables the app to provide feedback on whether the individual should blow less or more and also tracks adherence to the strengthening program.
