BACKGROUND AND STUDY AIMS: Hepatic steatosis seems to be frequently found histopathologically in chronic hepatitis C virus (HCV)-infected patients. The aim of this study is to determine the influence of steatosis on HCV disease severity  (fibrosis) and to evaluate its impact on sustained virological response (SVR) to  antiviral therapy.

PATIENTS AND METHODS: From April 2008 to April 2010, 148 consecutive adults (87 females (59%) and 61 males (41%); mean age: 55.2 years) with HCV admitted for liver biopsy were included in this retrospective study. At least one element of metabolic syndrome was identified in all cases: Obesity (n=44), hyperlipidaemia (n=40), hypertension (n=29) and diabetes (n=21). Liver fibrosis was classified according to the Metavir score and hepatic steatosis described as following: S0:  absent; S1: minimal (<30%); S2: moderate (30-60%); and S3: severe (>60%). Patients were divided into two groups: S0S1 group (absent or minimal steatosis) and S2S3 group (moderate to severe steatosis). Of the 148 patients, 53 were treated with pegylated interferon and ribavirin combination therapy.

RESULTS: Steatosis was found in 40 patients (27%): S1 in 72.5%, S2 in 17.5% and S3 in 10% of cases. The distribution of patients according to the degree of fibrosis was as follows: in the S0S1 group, F1=12.4%, F2=36.5%, F3=21.1% and F4=21.1% and in the S2S3 group, F1=9%, F2=45.5%, F3=18.2% and F4=27.3%. There was no difference between the two groups regarding the degree of fibrosis (p≥0.80). The rate of SVR was 64%: 63% in the S0S1 group and 75% in the S2S3 group. The difference was not statistically significant (p=1).

CONCLUSION: Steatosis was found in 25% of cases. Liver steatosis in chronic hepatitis C is not a negative prognostic factor of response to combined antiviral therapy. These results must be confirmed by a large series of patients.
