OBJECTIVES: Describe the clinical and biochemical characteristics of patients with histopathological findings compatible with steatohepatitis of HNAL patients between 2010-2012. Determine the frequency of alcoholic and non-alcoholic steatohepatitis, presence of metabolic syndrome and other factors associated to non-alcoholic steatohepatitis, its main indications for liver biopsy and biochemical characteristics according to the severity of the histological findings. MATERIALS AND METHODS: We evaluated all histological slides of liver biopsies of the period between 2010-2012, of which, those with the diagnosis of steatohepatitis were selected. Their medical records were then reviewed. RESULTS: 32 patients met inclusion criteria. 28 were female and 4 male, the average age was 49±12 years. Two patients had a history of chronic alcohol consumption, representing the group of alcoholic steatohepatitis. The more frequent clinical finding in patients with NASH (non-alcoholic steatohepatitis), was obesity (37%). 50% of patients had AST/ALT ratio <1. CONCLUSIONS: Among population studied, non-alcoholic steatohepatitis was more common than alcoholic steatohepatitis, being obesity the most associated factor.
