Nonalcoholic steatohepatitis(NASH) is the progressive form of Non-alcoholic fatty liver disease (NAFLD), is characterized by hepatocellular damage, inflammation, and liver fibrosis that can progress to cirrhosis, in 25% of patients, NAFLD progresses to NASH, which increases the risk for the development of cirrhosis, liver failure, and hepatocellular carcinoma. In patients with NASH, liver fibrosis is the main determinant of mortality.~Pentoxifylline (PTX) is a xanthine derivative drug with a wide range of actions at the cellular and molecular level. PTX possess anti-inflammatory, antioxidant activities. PTX have potential role in improvement of NASH . Also, PTX inhibits a number of pro-inflammatory cytokines including interleukin-1, interleukin-6 and tumor necrosis factor (TNF-α ) which play an important role in the pathogenesis and progression of NASH.
The aim of the present study is to evaluate the efficacy and safety of pentoxifylline in the treatment of non-alcoholic steatohepatitis patients.
