About this study

The primary goal of this study is to identify a set of genotypes that increase the risk for nonalcoholic fatty liver disease (NAFLD) and predispose individuals to increased de novo lipogenesis (DNL) and liver fat accumulation when exposed to fructose intake. The proposed goal will be achieved through the completion of following aims:

  1. To determine the impact of prolonged exposure of fructose on hepatic lipid accumulation in Caucasian individuals with high and low genetic risk for NAFLD,
  2. to determine the impact of acute exposure of fructose on hepatic DNL, and
  3. to determine the relationship between markers of DNL, liver fat accumulation and serum concentrations of lipids, uric acid and liver function markers before and after the fructose challenge.
Read the detailed description

BACKGROUND AND RATIONALE Non-alcoholic fatty liver disease (NAFLD) is characterized by fat accumulation in liver cells not caused by alcohol. A leading cause of chronic liver disease in the US, NAFLD represents a group of disorders including steatosis, nonalcoholic steatohepatitis with fibrosis. It has substantially risen in prevalence over the last two decades with the estimated prevalence being 20% among US adults and 25% in young adults (18-39 years). Over 64 million individuals are believed to have NAFLD with annual medical costs rising to more $100 billion. More common in individuals who are obese or diabetic and/or have metabolic syndrome, NAFLD has been associated with increased cirrhosis, liver-related mortality and hepatocellular carcinoma.

Both genetic and environmental, including nutritional, factors contribute to the onset and progression of NAFLD. Increased consumption of sugar-sweetened, fructose-rich beverages has been linked to NAFLD. Fructose, commonly found in soft drinks, fruit juices and energy drinks, affects many metabolic processes, foremost being an increase in fat accumulation in the liver and hence, NAFLD. Genome-wide and candidate gene studies have identified several genes associated with NAFLD. However, none of these studies have shown the cumulative effects of single nucleotide polymorphisms (SNPs) on changes in liver fat when exposed to fructose. The results from this study can be extrapolated to larger cohorts and other ethnicities and are therefore, expected to lay the foundation for developing personalized nutritional plans.

What participants receive

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

  • Sugar drinkOther

    A sugar drink made with 1.2 g/kg body weight of added sugar( 0.75g/kg body weight of fructose + 0.45g/kg body weight of glucose) and 24oz water

Study groups in NCT03783195
Study groupRoleWhat they receive
High GRS groupExperimentalThis group consists of individuals who are in the highest quartile of the genetic risk score (GRS) and will ingest one sugar drink (equal to 2 soft drinks) per day for 3 weeks. The GRS is computed by adding the number of alleles that increase the risk for liver lipogenesis or fatty liver.
Receives: Other: Sugar drink
Low GRS groupExperimentalThis groups consists of individuals who are in the lowest quartile of the genetic risk score (GRS) and will ingest one sugar drink (equal to 2 soft drinks) per day for 3 weeks. The GRS is computed by adding the number of alleles that increase the risk for liver lipogenesis or fatty liver.
Receives: Other: Sugar drink

Questions about this trial

What is this clinical trial studying?

A study testing Sugar drink in people with NAFLD, run by University of North Carolina, Chapel Hill at 1 site in United States.

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 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 23 Oct 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 United States. 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 23 Oct 2024). 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?

Mean Change in Liver Fat Content Based on Elastography (time frame: between week 0 (Baseline) and week 3). The study lists 4 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 NCT03783195, which also lists 27 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 23 Oct 2024.
