Active clinical trials for "Sleep Apnea Syndromes"

This investigator-initiated study aims to determine the effects of BAY2586116 (a novel TASK channel blocker nasal spray) on sleep apnoea severity and the potential influence of route of breathing.

Obstructive sleep apnea (OSA) is a type of sleep-related breathing disorders that is characterized by a sleep-related constriction (obstruction) of the upper airways. The treatment with continuous application of positive airway pressure (CPAP) via respiratory mask forms the therapeutical standard of OSA. The autoCPAP (automatic positive airway pressure: APAP) therapy is an additional treatment option for patients with more unstable conditions (e.g. due to sleep position) which is characterized by a dynamic adaption of the applied airway pressure according to patients therapeutical needs. Device usage time and therapy adherence are crucial for treatment success. The purpose of this study is to assess the effect of a digital patient support (DPS) tool, complementary to standard care on continuous and automatic positive airway pressure (CPAP, APAP) adherence and daytime sleepiness after 12 weeks in patients diagnosed with severe obstructive sleep apnea (OSA). All patients with apnea-hypopnea index (AHI) ≥ 30 per hour are prospectively included and randomized to receive standard care (SC) or standard care with personalized DPS via prisma APP prototype version (SC+DPS). In both arms, initiation of therapy and standardized therapy control after 12 weeks is carried out identically. Patients in the SC+DPS arm received additionally automated feedback on their therapy and motivational messages, as well as therapy recommendations.

This observational study aims at establishing the proportion of patients suffering from endometriosis and for whom an Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) diagnosis is established. The study participation will be offered to endometriosis patients displaying symptoms that may suggest an underlying OSAHS. OSAHS diagnosis will be made according to standard of care practice and patients will be followed up to 12 months after initiating the OSAHS treatment to fill in questionnaires assessing the impact of OSAHS treatment on various endometriosis-related symptoms

Background. Atrial fibrillation is one of the most common complications in the postoperative period of coronary artery bypass grafting (CABG) surgery and usually associated with increased length of hospital stay and higher hospital costs. Among the main mechanisms involved, excessive sympathetic activation, oxidative stress and inflammation are fundamental elements in the pathophysiology of obstructive sleep apnea. Objectives. To evaluate the effects of continuous positive airway pressure (CPAP) in reduction of atrial fibrillation after CABG in patients with obstructive sleep apnea. Methodological procedures: A multicenter randomized controlled study to compare the incidence of atrial fibrillation between the intervention group and the control group, both monitored seven days with Holter.

Adenotonsillectomy (AT) is one of the most common pediatric surgeries performed, and is estimated to comprise 530,000 procedures in children under 15 years of age. Historically, the leading cause for these procedures was recurrent infections; however, more recently surgical indications include sleep disordered breathing and obstructive sleep apnea (OSAS). Pre-operative polysomnography (PSG) is recommended for all children with suspected OSAS prior to undergoing AT, although it is unclear whether sleep disordered breathing characteristics predict post-operative outcomes or complications. Obesity has become an epidemic in the pediatric population. More recently, an increased population of obese children are presenting for AT with upper airway obstruction with or without tonsillar hypertrophy, which is similar to the adult etiology of OSAS. Obesity is a multisystem disease, causing fatty liver and cardiac disease, defects in glucose metabolism, insulin resistance, leptin resistance, and creates a state of chronic inflammation. Markers for inflammation, including tumor necrosis factor (TNF)-α, C-reactive protein (CRP), leptin, interleukin (IL)-6 and IL-10, are abnormal in obese patients and have also been linked to more severe OSAS disease in children even after controlling for BMI. In pediatrics, medication dosing is based on an actual body-weight calculation, however, recent reports suggest that this dosing method is over-dosing patients with obesity. Therefore, increased respiratory complications after surgery may be related to inappropriate intra-operative opioid dosing. Specific Aim 1 (SA1): To compare morphine pharmacokinetics in normal children <=12 years of age, non-obese children with severe OSAS, and obese children with severe OSAS. The investigators hypothesize that obesity independently enhances morphine pharmacokinetics. Specific Aim 2 (SA2): To determine whether biomarkers related to obesity, chronic inflammation, and OSAS predict changes to morphine pharmacokinetics. The investigators hypothesize that inflammatory and obesity-related biomarkers are elevated in overweight children with OSAS, more so in obese children with OSA, compared to lean children with OSAS. In addition, the investigators hypothesizes that leptin independently is linked to altered morphine pharmacokinetics.

This investigation is designed to evaluate the performance (leak and comfort) as well as the participant's overall acceptance of the trial nasal mask amongst Obstructive Sleep Apnea (OSA) participants. An important factor in this investigation will be the testing of two different seal sizes on the participants (medium and large size). A total number of 12 participants who currently use nasal or nasal pillow masks will be recruited for the trial. Participants have been selected based on their anthropometric measurements collected in previous trials (CIA-103). Participants from previous NZ trials may be recruited into this trial with their consent. All the participants will be recruited from the Fisher & Paykel Healthcare Database of subjects with OSA (Ethics Reference NTY/08/06/064), Auckland District Health Board (ADHB) and New Zealand Respiratory and Sleep Institute (NZRSI). Participants will use the trial mask in home for a period of 7 ± 3 days and also 1 overnight polysomnography session at the Fisher & Paykel Healthcare sleep lab. Baseline data will be collected from the participant during the first visit, 7 days of CPAP usage data will be downloaded and stored for analysis. The participant will use the trial device on their usual Continuous or Auto Positive Airway Pressure (CPAP/APAP) setting and device for the duration of the trial.

The overall purpose of this study is to determine whether the oral medication dimethyl fumarate is an effective treatment for obstructive sleep apnea in patients who are unable, unwilling, or uneager to use positive airway pressure therapy.

Obstructive sleep apnea (OSA) syndrome affects up to 5% of the general population. The prevalence is multiplied by 13 in coronary artery disease (CAD) patients. Many studies have shown that OSA syndrome was the main risk factor for cardiovascular morbidity and mortality (RR = 9.1 [95%, 2.6 to 31.2]). If the value of treatment with Continuous Positive Airway Pressure (CPAP) in symptomatic CAD patients (daytime sleepiness and/or 2 clinical symptoms with Apnea Hypopnea Index (AHI) ≥ 20) appears to be established, treatment with CPAP in asymptomatic CAD patients (with AHI> 30) may be too demanding. Alternative treatments are rare and results are highly variable. Therefore, it would be interesting to suggest other treatment modalities with moderate coronary and/or minimally symptomatic OSA syndrome.

To study the effects of compression stockings on sleep apnea in hemodialysis patients with diagnosed obstructive sleep apnea. The rationale of this study consists in the fluid shift theory, which consists in the nocturnal rostral fluid shift from legs, which causes upper airways edema. The aim of this study is to evaluate if compression stockings could improve such nocturnal volume redistribution and, therefore, improve obstructive sleep apnea.

Published data indicate that obstructive sleep apnea syndrome (OSAS) worse the prognosis of coronary artery disease (CAD) and that oxidative stress can link this 2 diseases. Investigators hypothesise that oxidative stress decrease after 3 months of continuous positive airway pressure (CPAP) in this specific population. The results may have major implication in the comprehension of physiopathologic processes linking OSAS and CAD and in the treatment of OSAS in this specific population.
