Brief Summary:
The purpose of this study is to determine whether nonalcoholic fatty liver disease NAFLD is associated with altered peripheral and hepatic insulin sensitivity and to investigate potential mechanisms underlying insulin resistance in NAFLD by determining associations between hepatic and peripheral insulin sensitivity hepatic steatosis dyslipidemia inflammatory cytokines glucose metabolism beta-cell function and body fat distribution
Detailed Description:
NAFLD and nonalcoholic steatohepatitis NASH are common liver disorders that are strongly associated with obesity type 2 diabetes and dyslipidemia The underlying pathophysiology of fatty infiltration of the liver is thought to be related to insulin resistance which is an almost universal finding in patients with NAFLD It is also possible that fat infiltration and inflammation in the liver may impair insulin sensitivity either locally in the liver or peripherally via the actions of inflammatory cytokines We hypothesize that insulin resistance is a major causal factor leading to fat deposition in the liver and NAFLD and thus interventions aimed at improving insulin sensitivity will result in a reduction of hepatic inflammation and steatosis
Specific Aim 1 To determine in a cross-sectional study whether NAFLD is associated with altered peripheral and hepatic insulin sensitivity and to study their relationships with hepatic steatosis dyslipidemia inflammatory cytokines glucose metabolism -cell function and body fat distribution Specific Aim 2 To determine in a 6 month placebo-controlled double-blinded treatment study if treatment with rosiglitazone an insulin sensitizer or fenofibrate a triglyceride lowering agent will improve both hepatic as well as peripheral insulin sensitivity and thereby improve hepatic steatosis and inflammation in subjects with NAFLD
The results of the proposed study will have important implications for our understanding of the mechanisms underlying insulin resistance and abnormalities in lipid and glucose metabolism in subjects with NAFLD and for the design of future studies aimed at the prevention and treatment of this condition
