About this study

To identify the early effects of obstructive sleep apnea on the cardiovascular system of children.

Read the detailed description

BACKGROUND:

Obstructive sleep apnea (OSA) is an important clinical disorder occurring in men, women, and children with a prevalence of 4 percent, 2 percent and 1-3 percent, respectively. OSA is under active study in adults and is definitely linked with increased cardiovascular morbidity, even in its mild to moderate clinical forms. In contrast, OSA has not been well studied in children and the potential deleterious consequences on cardiovascular function have received little or no attention.

DESIGN NARRATIVE:

The study will examine in children 1) The interaction between OSA and baroreflex dysfunction, 2) The relation of OSA severity and baroreflex dysfunction to abnormalities in blood pressure control during wakefulness and sleep, 3) The association of the diminished baroreflex gain and impaired blood pressure control with an index of end organ damage, the left ventricular mass index, and 4) Whether effective treatment of OSA results in significant improvement in baroreceptor function, blood pressure control and a decrease in left ventricular mass index. A cross-sectional study will be conducted in 8-12 year old children with OSA and a matched group of normal children. Studies include baroreceptor function, 24-hour ambulatory blood pressure and left ventricular mass index. Baroreceptor function will be measured by non-invasive techniques based on combined computer analysis of heart rate and blood pressure measured by portapres. 24-hour ambulatory blood pressure will be measured by a Spacelab monitor and left ventricular mass index will be measured by direct M-mode echocardiogram. A longitudinal study will be conducted on the effect of adequate treatment of OSA on baroreceptor function, daytime and nocturnal blood pressure and left ventricular mass index. A cohort of children with OSA and a matched group of normal controls will be followed for a period of 12 months after treatment of the disorder. Results are expected to show that children with OSA have decreased baroreceptor sensitivity, elevated nocturnal blood pressure and increased left ventricular mass index and that effective therapy for OSA, as determined by polysomnography, will improve or normalize baroreceptor sensitivity as well as nocturnal blood pressures and will lead to a decrease in left ventricular mass index.

Questions about this trial

What is this clinical trial studying?

An observational study of Cardiovascular Diseases and Heart Diseases, run by Children's Hospital Medical Center, Cincinnati.

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

Who may be eligible to take part?

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 4 May 2017. Status can change between updates, so confirm with the study contact before making plans.

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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00059111, which also lists 4 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 4 May 2017.
