NCT ID: NCT06376305 Completed - Obesity Clinical Trials

EndoBarrier in Obstructive Sleep Apnoea Study

End-OSA
Start date: March 2016
Phase: N/A
Study type: Interventional

Obstructive sleep apnoea (OSA) is a common condition in which the upper airways (windpipe) collapse repeatedly during sleep, blocking the flow of air into the lungs. It is characterized by repetitive pauses in breathing during sleep, despite the effort to breathe, and is associated with a reduction in the amount of oxygen in the blood (oxygen saturation). People with OSA are at risk of heart disease, high blood pressure, stroke, depression, and premature death. OSA is usually treated using a continuous positive airway pressure (CPAP) machine. This involves the patient wearing a face mask during sleep which is connected to the machine which supplies a constant steam of air to help keep the airways open. This improves the symptoms and hopefully the long-term outlook, but it is an uncomfortable solution. OSA is associated with obesity and weight loss can improve or even cure it. Treatment with EndoBarrier (placement of a thin flexible tube that is placed inside your intestine creating a physical barrier between the intestinal wall and the food so less can be absorbed) can be associated with significant weight loss and can improve blood sugar control in patients with type 2 diabetes related to their weight (diabesity). This study aims to find out if EndoBarrier treatment can improve OSA in patients with diabesity to the extent that some patients no longer require their CPAP machine treatment.

Minimally invasive off the shelf medical devices will be used and observation of the characteristic physiological responses to stimulation of the HGN, will be assessed.

NCT ID: NCT06265129 Completed - Clinical trials for Obstructive Sleep Apnea

The Association Between Obstructive Sleep Apnea Severity and Red Blood Cells Indices

Start date: March 20, 2023
Phase:
Study type: Observational [Patient Registry]

Obstructive sleep apnea syndrome (OSAS) is characterized by recurrent episodes of obstructive events (apnea and hypopnea) and intermittent hypoxia, which in turn contributes to the systemic inflammation that underlies this disease and its consequences (Ryan et al 2009, Gileles-Hillel et al 2014). This systemic inflammation leads to endothelial dysfunction, which contributes to the pathogenesis of cardiovascular complications in OSAS, in addition to the exposure to risk factors, such as male gender, older age, obesity, and lack of exercise (Lorenzi Filho et al 2010). Some red blood cells (RBC) and platelets indices have emerged as inflammatory biomarkers in various diseases (Tertemiz et al 2016) The severity of OSA is significantly associated with increase hematocrit, even after controlling for possible confounding variables. However, nocturnal hypoxemia in OSA does not usually lead to clinical polycythemia (Choi et al 2006). In patients referred with a clinical diagnosis of OSAS, RDW may be a marker for the severity of the condition. As RDW is usually included in a complete blood count, it could provide an inexpensive tool for triaging OSAS patients for polysomnography evaluation (Sökücü et al 2012). The hematological indices white blood cell count (WBC), neutrophil count, lymphocyte count, mean platelet volume (MPV), platelet distribution width (PDW), and red blood cell distribution width (RDW) have been proposed as alternative markers to those normally used clinically, e.g., interleukin-6 (IL6) and C-reactive protein, to evaluate the burden of inflammation in OSAS (Wu et al 2018)

NCT ID: NCT06161389 Completed - Apnea Clinical Trials

Applied Forces During Neonatal Face Mask Ventilation With Different Face-mask Air Cushion Volumes

ForVol
Start date: December 11, 2023
Phase: N/A
Study type: Interventional

Positive pressure ventilation (PPV) is the most important intervention in neonatal resuscitation. During PPV, it is important to hold the face-mask with care, as applying excessive pressure could cause injury to the infant, while insufficient pressure could be a contributor of mask leak and reduced effective ventilation. Application of positive pressure to face structures may trigger a vagally mediated reflex via the trigeminal nerve that innervates the skin of the face leading to apnoea and a decrease in heart rate (TCR, trigeminal-cardiac reflex). In neonatal manikins, ventilation with a partially or fully inflated face mask does not seem to result in differences in mask leak. The force exerted by providers to improve mask seal might result in pressure lesions and in the elicitation of the trigeminal-cardiac reflex. However, information about the applied forces is unknown.

NCT ID: NCT06152692 Completed - Clinical trials for Obstructive Sleep Apnea

Circadian Intraocular Pressure Patterns in Patients With Sleep Apnea Syndrome and Treatment With Continuous Air Pressure

Start date: January 2016
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate the influence of sleep apnea-hypopnea syndrome (SAHS) syndrome and treatment with continuous air pressure (CPAP) on the circadian intraocular pressure (IOP) patterns and its structural impact on the nerve fiber layer of the retina to analize the relationship between SAHS and glaucoma. OBJECTIVES: 1. To study the PIO and its fluctuations in patients with SAHS before starting treatment with CPAP. Objective 2. To assess the effect of CPAP on circadian IOP patterns. 3. Evaluate the effect of changes in IOP in patients with OSA treated with CPAP in the nerve fiber layer of the retina. METHODS: A prospective study to be monitored continuously for 24 hours IOP by contact lens device Sensimed Triggerfish (Sensimed AG, Switzerland). Objective 1. To monitore and compare the IOP for 24 hours at 74 patients diagnosed with SAHS before starting treatment with CPAP and 37 patients without OSA. Objective 2. To study the impact of CPAP treatment by a study design in two stages CPAP / sham CPAP. A first monitoring of IOP will be compared before starting treatment with CPAP, with monitoring a month (CPAP-sham CPAP) and 12 months after initiation of treatment with CPAP. Objective 3. To correlate the values obtained from the monitoring of IOP in the thickness of the nerve fiber layer of the retina, as measured by optical coherence tomography, at baseline and at 12 months after starting treatment with CPAP.

NCT ID: NCT06119841 Completed - Clinical trials for Obstructive Sleep Apnea

Tonsillectomy and Expansion Sphincter Pharyngoplasty Operations

Start date: January 1, 2022
Phase: N/A
Study type: Interventional

Background: To compare the efficacy of tonsillectomy and expansion sphincter pharyngoplasty (ESP) in the surgical treatment of obstructive sleep apnea (OSA). Methods: Patients with Friedman grade III-IV tonsil hypertrophy and OSA diagnosed with polysomnography were separated into two groups according to the surgery performed, as the classic tonsillectomy group (Group 1) and the ESP group (Group 2). The primary endpoint of the study was to determine the Apnea-Hypopnea Index (AHI) value. The preoperative and postoperative AHI scores and the decreases in these scores were noted. The change in AHI was calculated as a percentage (preoperative AHI - postoperative AHI/ preoperative AHI x 100) and the two groups were compared. An AHI value of <10 events/hour was accepted as cure.
