    Abstract:
    Nonalcoholic steatohepatitis (NASH), which is considered the hepatic manifestation of the metabolic syndrome is an increasingly cause of chronic liver disease in Japan. NASH is finally lead to liver cirrhosis and hepatocellular carcinoma as viral hepatitis, therefore, medical treatment should be considered, when NASH occurs. Treatment of patients with metabolic syndrome has been focused on the management of associated conditions such as obesity, hyperlipidemia, hypertension and hyperinsulinemia. Insulin resistance, that could accelerate liver inflammation and fibrosis by up-regulation of TNFa seems to be most important factor in many cases of NASH. The insulin-sensitizing drugs, which were biguanides (metformin) and thiazolidinediones (pioglitazone) have been shown to correct not only insulin resistance but also steatosis and inflammation in the liver. Metformin and pioglitazone might be useful drugs against NASH, however further investigations were needed.
