NCT01966627

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • gene expression

    gene mutation allele variation identification measure via gene extraction

    Baseline

Secondary Outcomes (2)

  • hepatic fat content

    2 years

  • glucose tolerance

    As indicated by Pediatric Hepatolgist

Study Arms (1)

Pediatric NAFLD Cohort

Overweight 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.

  • overweight or obese with a BMI greater than the 85th percentile for age and gender, and
  • be otherwise healthy.

You may not qualify if:

  • the use of any medication that alters liver function, blood pressure, glucose or lipid metabolism and
  • no use of any antipsychotic medication
  • Youth on chronic anti-inflammatory medications or who consume alcohol are also excluded.
