title: [Hepatic steatosis: clinical-statistical study of patients diagnosed by histological or ultrasonographic methods].
abstract: OBJECTIVE
  This study wants to document eziopathogenetic factors and clinical, instrumental and hystological characters that associate to the various types of hepatic steatosis.
  
  
  METHODS
  In this retrospective study have been examined two different groups of randomized patients. The "Group 1" comprehended 70 patients with hystologic diagnosis of hepatic steatosis (steatohepatitis--SH--60%; steatosis--SE--40%). The "Group 2" comprehended 70 patients with ultrasonographic pattern of fatty liver (slight degree: 70%; severe degree: 30%).
  
  
  RESULTS
  Analysis of results relative to the "Group 1" showed the role of HCV-infection in etiopathogenesis of the SH, significantly greater than in SE (76.2% vs 25%; p < 0.0001). SE is often associated with exogenous noxae (alcoholism: 28.6%; use of long-term medications: 14.3%) or metabolic disorders (hyperglycemia 28.6%, hyperlipidemia 42.8%, obesity 25%). Haven't seen differences of clinical data or serum liver tests between SE and SH. Histological features that predicted the development of cirrhosis and/or fibrosis are more frequent in SH (SH: 40.4% vs SE: 10.7%; p < 0.01). The analysis of "Group 2" hasn't shown differences of clinical data or serum liver tests between slight and severe degree.
  
  
  CONCLUSIONS
  Analysis of results relative to the two groups of patients ones has shown that SE and SH are thick asymptomatics and associated at hepatomegaly and at increase of ALT, AST, gamma GT. The increase of ALT and/or AST leads to search for the markers of HBV and HCV; when they are positive, hepatobiopsy is necessary for the diagnosis of possible SH or evolutive state to liver cirrhosis.
