About this study

Official title: Non-invasive Assessment of Endothelial Function in Children and Adolescents With Type 1 Diabetes Mellitus Using Isometric Handgrip Exercise -MRI: A Feasibility Study

This project aims to assess coronary vessel response to isometric handgrip exercise (IHE) during magnetic resonance imaging (MRI) in children with T1D children and healthy controls. The investigators will compare the groups in terms of surrogate markers of intima media alteration and arterial stiffness, i.e. carotid intima media thickness (CIMT) and aortic pulse wave velocity (PWV).

Read the detailed description

Background Type 1 diabetes mellitus (T1D) in children and adolescents is associated with significant cardiovascular morbidity and mortality. Early detection of vascular dysfunction is key to management yet assessment is invasive - which is particularly challenging when considering pediatric patient populations. Recently, a novel approach using isometric handgrip exercise (IHE) during magnetic resonance imaging (MRI) has been developed to evaluate coronary endothelial function in adults.

This project aims to assess coronary vessel response to IHE using MRI in children with T1D children and healthy controls. In addition, the investigators will compare the groups in terms of surrogate markers of intima media alteration and arterial stiffness, i.e. carotid intima media thickness (CIMT) and aortic pulse wave velocity (PWV).

Community-dwelling healthy volunteers (<18 years-old) and children with type 1 diabetes mellitus (disease duration ≥ 5 years) are recruited. IHE-MRI studies are conducted and measurements are recorded at rest (baseline) and under stress (IHE at 30% maximal effort). Carotic Ultrasound and Sphygmocor CPV System are used to assess CIMT and PWV respectively. Student's T-tests are used to compare results between groups.

What participants receive

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

  • Isometric Handgrip Exercise during magnetic resonance imagingDiagnostic test

    Coronary endothelial function are assessed by MRI with imaging studies done at baseline (at rest) and during IHE (under stress). Maximum grip strength is determined using an MRI-compatible dynamometer (Grip Force Fiber Optic Response Pad, Current Designs Inc., Philadelphia, USA) prior to baseline imaging.

What is being measured

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

  1. Change in coronary cross sectional area (mm2)

    Change from rest to that during isometric handgrip exercise (IHE).

Questions about this trial

What is this clinical trial studying?

A study testing Isometric Handgrip Exercise during magnetic resonance imaging in people with Type 1 Diabetes Mellitus and Coronary Artery Disease, run by University of Lausanne Hospitals at 1 site in Switzerland.

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 2 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 22 Jun 2021. 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 Switzerland. 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?

Change in coronary cross sectional area (mm2) (time frame: Baseline and up to 3 years). 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 NCT03506711, which also lists 2 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 22 Jun 2021.
