About this study

assess the relationship between obstructive sleep apnea and endocrine, inflammatory, and metabolic bio-markers in consecutively enrolled adult male patients with a clinical suspicion of obstructive sleep apnea.

Read the detailed description

Obstructive sleep apnea (OSA) is a disorder with high prevalence, estimated to occur in 34% of men and 17% of women , afflicting more than 100 million adults worldwide.

OSA is the third most common serious respiratory condition after Asthma and COPD.

Patients with untreated OSA are at increased risk for hypertension, cardiovascular disease, heart failure, stroke, obesity, metabolic dysregulation, diabetes mellitus, daytime sleepiness, depression, accidents and are a significant burden on the healthcare system.

Unfortunately, up to 90% of individuals with OSA remain without a diagnosis or therapy.

The association between OSA and adverse health consequences has led the American Heart Association and others to suggest that OSA screening be integrated into routine clinical care.

Current tools for OSA screening rely on questionnaires with low diagnostic accuracy from low-quality studies, as reported in meta-analyses, OSA screening measures that are frequently used include the Epworth Sleepiness Scale (ESS) and STOP-Bang questionnaires.

The ESS assesses subjective daytime sleepiness but is nonspecific for OSA, was not designed nor validated for OSA screening.

The recent American Academy of Sleep Medicine (AASM) clinical practice guidelines report that more accurate and user-friendly screening tools, such as blood bio-markers, are needed to better predict OSA diagnosis and severity, a recent review of potential OSA bio-markers concludes that an optimal screening test should be clinically sensitive, specific, simple, timely, inexpensive, and correlate to disease severity.

Furthermore, bio-markers should make pathophysiological sense, reflecting functional changes that accompany OSA.

Numerous individual OSA blood bio-markers have been studied previously dysfunctions in metabolic and endocrine systems induced by OSA, chronic inflammation, hypoxemia, sleep fragmentation, and stress are associated with alterations in bio-markers. These bio-markers include glycated hemoglobin (HbA1c), C-reactive protein (CRP), erythropoietin (EPO), and uric acid,Unfortunately, the diagnostic utility of individual bio-markers or combinations of markers is inconclusive in identifying OSA.

  • biomarkersDiagnostic test

    bio-markers testing will be made to all suspected OSA patients(CRP, Hba1C,uric acid, ESR, plasma fibrinogen, pentraxin3), and to control cases.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Validity of biomarkers to screen for obstructive sleep apnea

    analysis of biomarkers results (which include Pentraxin 3, HbA1C,Uric acid,CRP,ESR,Plasma fibrinogen) will be assessed and compared to the results of polysymnography

    Measured: baseline

Secondary outcomes (1)
  1. Inflammatory biomarker level in OSA patients compared to controls

    Inflammatory biomarkers which include ESR , CRP and pentraxin 3 will be measured and compared in both cases and controls.

    Measured: baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Obstructive Sleep Apnea, run by Assiut University.

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 1 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 17 Sep 2019. 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?

Results are not available in the source record.

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

Contact Abuzaid (01064756136, anaover32@yahoo.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Validity of biomarkers to screen for obstructive sleep apnea (time frame: baseline). 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 NCT04093102, 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 17 Sep 2019.
