About this study

Official title: Multiple Sclerosis: The Role of Mitochondrial Dysfunction in Insulin Resistance

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system (CNS) and is one of the most common neurological diseases, often leading to disability of the patients. The MS pathogenesis includes vascular and inflammatory components, however recently also the role of mitochondrial dysfunction being a hot topic in neurodegeneration.

Read the detailed description

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system (CNS) and is one of the most common neurological diseases, often leading to disability of the patients. The MS pathogenesis includes vascular and inflammatory components, however recently also the role of mitochondrial dysfunction being a hot topic in neurodegeneration. Current project is based on previous project results, where the investigators of this project found signs of insulin resistance (IR) with hyperinsulinemia in patients with MS, which seem not to be related to chronic inflammation or low physical activity. Therefore aim of the present project is to elucidate impact of mitochondrial dysfunction in the pathogenesis of impaired insulin action and its role in the neurodegenerative process. To test the hypothesis, mitochondrial function, endothelial function, changes in membrane proteins and function of autonomic nervous system will be assessed. Those parameters will be measured non-invasively and in samples of blood, cerebrospinal fluid and skeletal muscle. MS patients will be examined at the time of diagnosis and after 12 months of treatment; healthy subjects will be used as controls. Elucidation of insulin resistance cause and the role of mitochondrial dysfunction in pathogenesis of disease is expected. Potential outcome of the project could be the answer, if pharmacological or non-pharmacological intervention might lead to improvement of mitochondrial function and therefore represent a new approach to prevent MS progression.

What is being measured

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

  1. Insulin sensitivity

    Insulin sensitivity indices calculated from plasma glucose and insulin concentrations during oral glucose tolerance test

    Measured: 2017-2019

Secondary outcomes (1)
  1. Expanded Disability Status Scale (EDSS)

    Expanded Disability Status Scale (EDSS) was developed for rating overall disability in MS. Patients are graded on the basis of presenting symptoms in eight different functional systems (FS), including pyramidal, cerebellar, brainstem, sensory, bowel and bladder, visual, mental, and other functions. Scoring of the EDSS uses a 0 to 10, 20-step scale, with 0 equal to normal neurological function, 6.0 requires an assistive device for walking and 10.0 equal to death due to MS. The final score is based on grades obtained in the FS assessment.

    Measured: 2017-2020

Questions about this trial

What is this clinical trial studying?

An observational study of Multiple Sclerosis and Mitochondrial Alteration, run by Slovak Academy of Sciences at 1 site in Slovakia.

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 4 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: finished, as of the sponsor's last update on 12 Apr 2023. 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 Slovakia. 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?

Insulin sensitivity (time frame: 2017-2019). 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 NCT03052595, which also lists 3 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 12 Apr 2023.
