About this study

Official title: Genetics of Fatty Liver Disease in Childhood Obesity.

This is a study to investigate genetic predisposition to hepatic steatosis and the expression of gluconeogenic and lipogenic genes in livers of obese children and adolescents.

Hypothesis 1: Common variants recently associated with variation in plasma TG levels identified in Genome Wide Association Studies (GWAS) (such as GCKR, PNPLA3) can affect accumulation of fat and subsequent development of Non Alcoholic Fatty Liver Disease (NAFLD). Gene variants act in additive or synergistic manner with progressive liver fat accumulation per additional risk allele.

Hypothesis 2: With increase in hepatic fat content NASH and fibrosis will increase. Furthermore, expression of lipogenic markers (SREBP1c) will increase.

Read the detailed description

To establish a cohort of obese youths to prospectively analyze potential factors (genetic and nutritional factors) that might affect the expression and progression of NAFLD. This study will determine genetic markers and their ability to convey susceptibility to NAFLD in obese children and adolescents. Furthermore, potential mechanisms that might contribute to the accumulation of hepatic Triglyceride (TG) accumulation will be, for the first time, assessed by genotyping. Additionally, we will examine the presence of intestinal microbiome in the development of fatty liver through stool collection.

Study groups in NCT01966627
Study groupRoleWhat they receive
Pediatric NAFLD CohortOverweight and obese children and adolescents at risk for non alcoholic fatty liver disease will undergo oral glucose tolerance testing (ogtt), genotyping, abdominal and liver magnetic resonance imaging (mri), and will provide a stool sample at baseline and at 2 year follow up. A small subset will undergo liver biopsy to test for hepatic steatosis and nonalcoholic steatohepatitis.
Receives: Other: ogtt; Other: genotyping; Other: abdominal and liver magnetic resonance imaging; Other: stool sample; Other: liver biopsy

What is being measured

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

  1. gene expression

    gene mutation allele variation identification measure via gene extraction

    Measured: Baseline

Secondary outcomes (2)
  1. hepatic fat content

    Abdominal MRI to measure liver fat and subcutaneous and visceral fat ratio done at baseline and 2 year follow up

    Measured: 2 years

  2. glucose tolerance

    glucose tolerance status measured by 3 hour oral glucose tolerance test done at baseline and 2 year follow up

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Non Alcoholic Fatty Liver Disease, run by Yale University 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 3 inclusion and 3 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 8 Dec 2017. 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?

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?

gene expression (time frame: Baseline). 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 NCT01966627, 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 8 Dec 2017.
