About this study

Official title: Mid-and Long-term Efficacy of Ventilation Non-invasive and Continuos Positive Airway Pressure in Obesity Hypoventilation Syndrome

Primary objectives: evaluate the efficacy of noninvasive ventilation (NIV) treatment versus continuous positive airway pressure (CPAP) and life style modification treatment in Obesity Hypoventilation Syndrome (OHS), with PCO2 (first phase) and days of hospitalization (second phase) analyzed as a primary variables and percentage of dropouts for medical reasons and mortality as operative variables. As secondary variables: Measure functional and clinical improvement during sleep and wakefulness, quality of life, echocardiography and the incidence and blood pressure and evolution of cardiovascular events. Objectives secondaries:role of apneogenic sleep events on molecular inflammation, endothelial damage and the genesis of diurnal hypercapnia. Methods:prospective, randomized controlled trial. Patients with OHS will be divided initially into two groups based on their apnea-hypopnea index (AHI) score, >=30 and < 30, using conventional polysomnography. The AHI >=30 group will be randomized to CPAP, NIV or life style modification treatments. The AHI <=30 groups will be randomized to NIV or life style modification treatments. Treatment efficacy at the medium- and long-term will be analyzed by comparing groups. The role of apneic events and leptin in the genesis of daytime alveolar hypoventilation will be analyzed by comparing the daytime PCO2/AHI coefficient between responders and non-responders to CPAP treatment, and the evolution of leptin levels in the four branches of the study. The role of apneic events in metabolic and biochemical alterations and endothelial dysfunction will be analyzed by comparing basal and post-treatment levels of related substances between groups, with and without significant AHI.

Read the detailed description

The AHI >=30 group will be analyzed to CPAP, NIV or life style modification treatments for two mouths.Once an evaluation is done during this period, the life style modification treatment will be randomized with the NIV/CPAP treatment for a continuation of three years.

Questions about this trial

What is this clinical trial studying?

A study testing life style modification, noninvasive ventilation, CPAP in people with Obesity Hypoventilation Syndrome, run by Sociedad Española de Neumología y Cirugía Torácica at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Sep 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Days of hospitalization (time frame: at least three years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01405976, which also lists 10 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Sep 2017.
