Active clinical trials for "Sleep Apnea Syndromes"

Study objective: To assess the nocturnal changes in mechanosensitivity and chemosensitivity in hypertensive sleep apnea-hypopnea syndrome (SAHS) patients and in SAHS patients with isolated nocturnal hypertension. To value the continuous positive airway pressure (CPAP) effect on these parameters. Design: Controlled cross-over longitudinal study. Settings: Madrid metropolitan area. Patients: Day-night sustained hypertensive and isolated nocturnal hypertensive patients with SAHS without previous treatment. At least 30 patients are needed. Interventions: Patients will allocate in each treatment arm (CPAP vs. sham CPAP) during three months. Explorations will perform before and immediately after sleep at 0-, 3-, and 6-months of trial. Measurements: 24-h urinary catecholamine, local vascular factors, angiotensin and aldosterone levels. Diaphragmatic tension-time index, metabolic rate, hypoxic withdrawal test, and ventilatory and inspiratory neural drive responses to progressive isocapnic hypoxia.

Recent evidences from small studies show potential benefit of acupuncture in the treatment of obstructive sleep apnea (OSA). These studies did not evaluate the benefit of the treatment on the cardiovascular system. Primary end-point: To investigate the effects of acupuncture in improving OSA severity among hypertensive patients. Secondary end-point To investigate the effect of acupuncture in improving the quality of life and sleep assessed by the Short Form 36 (SF-36) questionnaire and Pittsburgh Questionaire (PSQI); To investigate the effect of acupuncture in blood pressure and arterial stiffness

This is a randomized control trial in people with diabetes and obstructive sleep apnea who will be randomly assigned for 3 months to PAP therapy along with healthy lifestyle and sleep education or healthy lifestyle and sleep education.

The aim of the study was to determine the long term effects of compliance with positive airway pressure therapy on blood pressure in both hypertensive and normotensive patients with obstructive sleep apnoea hypopnoea syndrome.

The hypothesis is that APAP with SensAwake improves wake-after sleep onset compared to APAP without SensAwake in a patient population with Obstructive Sleep Apnea Syndrome (OSAS) and Insomnia.

This research is being conducted to examine the effects of nasal insufflation of warm and humidified air through a small nasal cannula on sleep, breathing pulmonary function, and daytime exercise capability.

The objective of the study is to confirm the safety and efficacy in patients utilizing the aura6000 System for the treatment of Obstructive Sleep Apnea (OSA).

Aim: To assess if six months of treatment with CPAP associated with conventional drug therapy, contribute to improved glycemic control in patients with type 2 diabetes and sleep apnea-hypopnea syndrome SAHS)

The aim of the study is to test the hypothesis that a new device would produce a significant decrease in obstructive breathing events during sleep as indexed by the Apnea Hyperpnoea Index (AHI) or Respiratory Disturbance Index (RDI) and measures of oxygen saturation during sleep.

Many individuals with Down syndrome (DS) have breathing problems during sleep. This is called obstructive sleep apnea syndrome (OSAS). OSAS is very common in individuals with Down syndrome because of the shape of their face and tongue and because of their low muscle tone. OSAS can cause a lot of health problems including behavioral and learning problems as well as heart problems. The purpose of this research study is to look at the effects of treating OSAS in individuals with Down syndrome with a machine called Continuous Positive Airway Pressure (CPAP). The investigators want to see if treatment of OSAS improves learning, behavior and heart problems.
