BACKGROUND: [corrected] Hepatic steatosis is a common finding in patients with hepatitis C, mainly virus C genotype 3. Steatosis in these cases might be associated with antiviral treatment response and with prognosis of chronic hepatitis.

AIMS: To determine the presence of steatosis and non-alcoholic steatohepatitis in chronic hepatitis C and its correlation with genotype and hepatic fibrosis.

PATIENTS AND METHODS: One hundred and twenty patients with chronic hepatitis C were retrospectively evaluated; genotype was done in 102 patients. All specimens were stained with hematoxylin-eosin, picrosirius and perls. Staging of hepatitis C was scored by Brazilian Classification and the diagnosis of non-alcoholic steatohepatitis by the American Association for the Study of Liver Diseases criteria

RESULTS: Steatosis was found in 65 of 120 cases (54.2%); it was mild in 37/65 (56.9%), moderate in 12/65 (18.5%) and severe in 10/65 (15.4%). In relation to fibrosis, 80 of 120 patients had mild fibrosis F0-F2 (66.6%) and 40 (33.3%) had more advanced fibrosis (F3 or F4). Steatosis was associated with genotype 3 (76.7%) in comparison with other genotypes (49,0%). There were no relationship between steatosis and advanced fibrosis F3/F4 (52,5%) or mild fibrosis (54,4%). Non-alcoholic steatohepatitis was diagnosed in 8/120 cases (6.7%) and was significantly associated with hepatitis C virus genotype 3 and with advanced fibrosis (F3 and F4)

CONCLUSIONS: The presence of steatosis and non-alcoholic steatohepatitis in chronic hepatitis C are associated to genotype 3; moreover non-alcoholic steatohepatitis was correlated with more advanced fibrosis.
