About this study

Official title: Exhaled Breath Proton Mass Spectrometry and Assessment of Endothelial Dysfunction in Patients With Respiratory Diseases

Assessment of cardiovascular disorders using echocardiography and arterial stiffness; comparative noninvasive assessment of volatile organic compound (eVOC) exhale breath patterns in patients with different chronic respiratory diseases with age and gender-matched healthy adults in order to identify a disease-specific exhaled eVOCs profiles and markers of respiratory and cardiovascular disorders.

Read the detailed description

Evaluating of eVOCs profiles by proton mass spectrometry with a time-of-flight (PTR-TOF) in patients with different chronic respiratory diseases is of great interest for assessing the prognosis and development of severe ventilation and cardiovascular disorders.

The aim of our study is to determine the diagnostic significance of PTR-TOF analysis in patients with chronic respiratory diseases and to identify specific eVOC markers of a severe ventilation and cardiovascular disorders in patients with different chronic respiratory diseases.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Breath test using the Compact PTR-TOF-MSDiagnostic test

    Breath samples will be analyzed with a proton-transfer reaction mass spectrometer (Compact PTR-MS, Ionicon, Austria) to obtain eVOCs profiles listed as ions at various mass-to-charge ratios (m/z).

  • Portable cardiac monitor "CardioQvark"Diagnostic test

    Record an electrocardiogram (ECG) in one lead with an assessment of the pulse wave using a portable cardiac monitor "CardioQvark" (Russia, LLC "L Card" , RU No. RZN 2019/8124 dated February 15, 2019) once. Devices automatically transfer data to the A\&D Connect app paired with it (link). When transferring data, they are completely protected. The data obtained using the application must be sent to the specialists of the research group in a depersonalized form.

  • Assessment of arterial stiffness using the VaSera VS-1500NDiagnostic test

    Assessment of arterial stiffness using the VaSera VS-1500N Fukuda Denshi device by non-invasive measurement of blood pressure in four limbs with simultaneous recording of ECG, PCG and pulse waves on the carotid, femoral arteries, as well as on the arteries of four limbs.

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Respiratory Diseases and Cystic Fibrosis, run by I.M. Sechenov First Moscow State Medical University at 1 site in Russia.

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 3 inclusion and 9 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: enrolling by invitation, as of the sponsor's last update on 30 Jul 2024. 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 Russia. 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?

This study is still under way. Results are not available in the source record yet.

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?

Molecular composition of exhaled breath analysed by proton-transfer reaction mass spectrometer (Compact PTR-MS, Ionicon, Austria) (time frame: up to 3 years). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 30 Jul 2024; AzTrials last refreshed its copy on 8 Nov 2026.
