Résumé
BACKGROUND: Hepatitis C is a worldwide chronic liver disease. Different factors have been found to be associated with an increased progression to severe liver fibrosis, such as alcohol intake higher than 30 g/day, older age at infection and co-infection. Nevertheless, different research centers have found conflicting data concerning the liver iron overload fibrogenic role. AIM: To assess the association between hepatic iron overload and fibrosis stage grades in hepatitis C Virus carriers, hepatic steatosis and demographic variables. METHODS: In this descriptive study we recruited 290 positive anti-HCV and qualitative HCV-RNA, treatment naive chronic hepatitis C outpatients registered fom 2007 to 2009 at the Federal University of Bahias Hospital. The variables studied in the liver biopsy results were: 1) fibrosis stage according to META VIR score (F0-F4), 2) iron overload presence or absence according to Perls staining, and 3) presence or absence of steatosis. Fibrosis stages were categorized as mild/moderate (F0-F2) and severe (F3-F4). Exclusion criteria were hepatitis B virus and human immunodeficiency virus co-infection, and primary or secondary hemochromatosis. The statistical analysis was performed using Chi-square and Students t tests, with the ssoftware: SPSS 17. A P value < 0.05 was considered as significant. RESULTS: Severe fibrosis was statistically associated with older age, iron overload presence (P = 0.003) and steatosis (P = 0.01). CONCLUSIONS: In this study hepatic iron overload and hepatic steatosis were associated with severe hepatic fibrosis (METAVIR F3-F4).
