About this study

Official title: Fructose Consumption Aggravates Dysregulation of Postprandial Lipid Metabolism in Obese Hypertriglyceridemic Men With High Cardiometabolic Risk Profile and Associates With Liver Fat Deposition

High fructose intake is increasingly recognized as causative in development of prediabetes, metabolic syndrome and cardiovascular disease (CVD). The mechanisms underlying fructose-induced metabolic disturbances are unclear but are beginning to be unraveled. In contrast to metabolism of glucose, the breakdown of fructose leads to the generation of metabolites that stimulate hepatic de novo lipogenesis (DNL) and increased levels of both fasting and postprandial triglycerides. The key lipogenic transcription factor seems to be activated by fructose independently of insulin. However, it is still controversial whether fructose consumption increases DNL in man to the extent that it induces metabolic disturbances. Animal studies have shown that also the adipose tissue is responsive to fructose feeding fructose, and that high fructose-feeding induces insulin resistance and inflammation in the adipose tissue. The role of intestinal insulin resistance in fructose-induced dysmetabolism has not been studied in detail. The critical question is whether the metabolic disturbances are induced by calorie excess or by fructose per se.

Read the detailed description

Detailed description: Study subjects will participate to studies 1-4 before and 3 m after fructose diet:

  1. An oral fat load or a kinetic study with stable isotopes combined with an oral fat load.
  2. Determination of liver, subcutaneous and intra-abdominal fat. (Proton magnetic resonance spectroscopy )
  3. Lipolytic enzymes, advanced lipid analysis, fat biopsies and genetic studies and gut microbiota profiling
  4. Oral glucose tolerance test and analysis of incretins and inflammatory biomarkers.

What is being measured

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

  1. TG Plasma AUC

    Before vs. after fructose challenge: Triglycerides (TG) plasma Area Under Curve (AUC)

    Measured: Form the baseline (time point 1) to end of treatment at 3 months (time point 2)

  2. B48 Plasma AUC

    Before vs. after fructose challenge: apolipoprotein (apo)B48 plasma Area Under Curve (AUC)

    Measured: Form the baseline (time point 1) to end of treatment at 3 months (time point 2)

  3. TG Plasma iAUC

    Before vs. after fructose challenge:Triglycerides (TG) plasma incremental Area Under Curve (iAUC)

    Measured: Form the baseline (time point 1) to end of treatment at 3 months (time point 2)

Secondary outcomes (4)
  1. DNL

    Before vs. after fructose challenge: de novo lipogenesis (DNL)

    Measured: Form the baseline (time point 1) to end of treatment at 3 months (time point 2)

  2. ApoC-III

    Before vs. after fructose challenge: Apolipoprotein C-III (ApoC-III)

    Measured: Form the baseline (time point 1) to end of treatment at 3 months (time point 2)

  3. β-OH Butyrate

    Before vs. after fructose challenge: beta-OH butyrate (β-OH butyrate)

    Measured: Form the baseline (time point 1) to end of treatment at 3 months (time point 2)

  4. Liver Fat

    Before vs. after fructose challenge

    Measured: Form the baseline (time point 1) to end of treatment at 3 months (time point 2)

Questions about this trial

What is this clinical trial studying?

A study testing Fructose in people with Central Obesity and Hypertriglyceridemia, run by Marja-Riitta Taskinen at 4 sites in 4 countries.

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 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: finished, as of the sponsor's last update on 15 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 4 sites in Canada, Finland, Italy, Sweden. 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?

Yes. Results are posted in the registry (first posted 15 Jun 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

TG Plasma AUC (time frame: Form the baseline (time point 1) to end of treatment at 3 months (time point 2)). 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 NCT01445730, which also lists 1 linked publication.

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 15 Jun 2021.
