Active clinical trials for "Obesity Hypoventilation Syndrome"

The Hypercapnia Telemedicine Outreach Program (E-TOUCH Study) aims to utilize telemedicine technology, as well as emergency medical services (EMS) home visits to address the problem with poor follow-up and compliance among Einstein's hypercapnic patients. The hypothesis is that reaching out to the subjects' homes will allow more consistent healthcare delivery, increase healthcare efficiency and compliance with therapy, and overall decrease acute decompensated states / hypercapnic respiratory failure, decreasing ED visits and hospitalization.

The aim of the study is to compare the efficacy and tolerance of autotitrating non-invasive ventilation (NIV) versus standard NIV in patients admitted to hospital with acute exacerbation of chronic respiratory failure. The investigators hypothesise that autotitrating NIV will ventilate patients with acute exacerbations of chronic respiratory failure as effectively as standard NIV.

This study aims to compare, in subjects with obesity-hypoventilation syndrome (OHS) treated by long-term non-invasive ventilation (NIV), resting energy expenditure (REE) in spontaneous breathing and under NIV. The hypothesise of this study is that REE will be lower under NIV than under spontaneous breathing.

We propose to carry out a large multicentric, multinational, randomized controlled trial with two phases (two sequential randomized controled trials) to answer two questions: 1) Should hospitalized patients with recently diagnosed OHS be discharged from the hospital on an auto-titratable NIV treatment until the diagnosis of OHS is confirmed in 3 months? 2) Is the long-term effectiveness of outpatient titrated CPAP non-inferior to titrated NIV in ambulatory patients with OHS 3 months after hospital discharge? Clinical practice, multicenter open-label controlled randomized clinical trial with preset allocation rate (1:1) with two parallel-groups conducted in centers from Spain, France, Portugal and USA. The study will have two phases with two randomizations. The first phase will be a superiority study and the second phase will be a non-inferiority study.

Investigate whether the course of an isolated nocturnal alveolar hypoventilation can predict the future occurrence of obesity-hypoventilation syndrome (OHS) in obese subjects

The ETAPES Program, a French national Experimentation in Telemedicine for the Improvement of Healthcare Pathways, was launched in 2018 for 4 years. Its objectives were to provide a temporary public reimbursement for medical telemonitoring in order to determine the benefits for the patient and the impact on medical organization and healthcare costs. In particular, this program applies to patients suffering from hypercapnic chronic respiratory failure and requiring home non invasive ventilation (NIV). For these patients, the ETAPES program combines NIV telemonitoring and therapeutic education. e-VENT study aims at evaluating the ETAPES program, implemented using the Chronic Care Connect™ telemonitoring solution, versus Standard of Care, on the effectiveness of home NIV, measured by average PtCO2, reflecting the level of nocturnal alveolar hypoventilation.

Patients with chronic hypercapnic respiratory failure can be successfully treated with home nocturnal non-invasive ventilation. Bi-level pressure support ventilators are at present the most frequently used ventilators for long term home ventilation. A recently commercialized bi-level ventilator offers the feature of automatically adjusting pressure support on the basis of a pre-determined ideal effective ventilation. Because this option may induce important swings in pressure support, and thus patient discomfort, and maybe increase leaks, we chose to analyse the impact of average volume assured pressure support (AVAPS) on patient comfort, subjective and objective quality of sleep and efficacy of ventilatory support.

Obesity is a major risk factor for obstructive sleep apnea (OSA). However, OSA is still largely under diagnosed in patients with a high cardiovascular risk. In this population the STOP-BANG questionnaire facilitates OSA screening. Moreover, blood bicarbonate concentration is a simple tool to screen for chronic respiratory disease and if elevated, is a marker of cardiometabolic comorbidities in obese patients. A combination of blood bicarbonate concentration and STOP BANG score could provide a cost-effective method of screening for OSA in obese patients. Such screening could enable earlier management and might significantly reduce the costs of treatment and improve the quality of life of patients at 2 years.

The critical nature of respiratory diseases, the continuously increasing prevalence of these conditions, and the subjective perception of patients vis-à-vis their pulmonary function and health status underscore the importance of home telemonitoring. These conditions are critical and necessitate close and regular monitoring that may be achieved at distance using telemonitoring. This study will assess a number of measures both at baseline and post-intervention from a number of domains, including Arterial Blood Gases (ABG), BiPAP-related data, chronic respiratory failure symptoms, health-related quality of life, patients satisfaction and utilization of healthcare resources.

The European Home Mechanical Ventilation Registry (EHMVR) will enable a thorough evaluation of HMV by documenting the characteristics of HMV patients and their treatment. This will facilitate a prospective, observational study to identify the primary indications for HMV, describe patterns of HMV use in European countries, and characterize changes in the initiation and utilization of HMV over time. The registry will target all adult individuals who have an indication for HMV. In the EHMVR, patient data from routine clinical care will be documented using an electronic case report form (eCRF). The eCRF will record: patient demographic data; diagnostic information (including primary diagnosis, 6-minute walk time, the presence of depression, and quality of life); blood gases; ventilation treatment (including type of ventilator, modes and settings, interfaces used); follow-up data (including failure rates, side effects, technical issues). An initial Pilot Phase will be launched with the aim to enrol at least 200 patients over a 6-month period to determine the feasibility of the registry. Steering committee members and their institutions will be the main participants in the Pilot Phase. After completion of the Pilot Phase, the registry will be expanded across Europe with the goal of enrolling approximately 10,000 patients over 5 years.
