Brief Summary:
Nonalcoholic fatty liver disease (NAFLD) is a clinical and pathological condition, whose spectrum can range from steatosis to steatohepatitis and cirrhosis, in patients without a history of alcohol abuse. Nonalcoholic steatohepatitis (NASH), the severe form of (NAFLD), has emerged as a clinically important type of chronic liver disease in industrialized countries and is characterized pathologically by hepatocellular ballooning, Mallory's hyaline, scattered inflammation and perisinusoidal fibrosis. NASH associated with cirrhosis can decompensate into subacute liver failure, progress to hepatocellular cancer and reoccur post transplantation.In the absence of established treatment, therapy is generally directed to treatment of risk factors for metabolic syndrome. Recently, some studies have been demonstrated that Polyunsaturated fatty acids (PUFAs), omega3 type, could reduced TNFalfa, IL6, aminotransferases, insulin resistance and steatosis verified by ultrasound. Neverthless, this is the first study that evaluate liver histology after six months of PUFA (omega3) in the treatment of patients with NASH.
