About this study

Official title: Study of the Role of Insulin Resistance in the Pathogenesis of the Metabolic Syndrome and of Non-alcoholic Steatohepatitis

The purpose of this study is to assess how the macronutrient composition of the diet effects

  • lipid and glucose metabolism
  • intrahepatic lipids
  • insulin sensitivity in healthy lean subjects and in subjects with a high metabolic risk (ie overweight and offsprings of patients with type 2 diabetes mellitus).
Read the detailed description

The study is aimed at assessing the effects of changes in total energy, sugars, lipids, and protein intake on intrahepatic lipids, plasma lipids, and hepatic and whole body insulin resistance in

  • lean men and women with no family history of diabetes
  • overweight men and women
  • lean men with a family history of type 2 diabetes

Subjects are studied after a 6-day period of

  • isocaloric diet with 100% calorie requirement, of which 55% carbohydrate, 15% protein, and 30% fat)
  • the same isocaloric diet supplemented with 3g/kg body weight/day fructose
  • hypercaloric high fat diet with 130% energy requirement, of which 55% carbohydrate, 15% protein, 60% fat
  • hypercaloric high fat+protein diet with 145% energy requirement, of which 55% carbohydrate, 30% protein, 60% fat

Measurements performed after 6 days on each diet include

  • intrahepatic and intramyocellular lipids (1H-MRS)
  • hepatic and whole body insulin sensitivity (hyperinsulinemic-euglycemic clamp)
  • body weight
  • plasma concentrations of hormones and substrates
  • gene expression profile in skeletal muscle (vastus lateralis) and adipose tissue (subcutaneous abdominal)

Questions about this trial

What is this clinical trial studying?

A study testing diet intervention in people with Metabolic Syndrome X and Liver Diseases, run by University of Lausanne 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 5 inclusion and 8 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 14 Jun 2018. 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?

plasma triglycerides (time frame: 6 days). 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?

On the ClinicalTrials.gov record for NCT00523562, 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 14 Jun 2018.
