Background: The role of gender in the progression of fibrosis in chronic hepatitis C is still under investigation., Aim: To investigate whether gender affects the progression of liver disease and/or hides other risk factors., Methods: A prospective series of 121 consecutive patients with chronic hepatitis C underwent liver biopsy. Grading and staging for chronic hepatitis were each evaluated according to Ishak's classification., Results: In univariate and multivariate analysis on the whole group of patients, male gender was not associated either with significant liver fibrosis (Ishak's score > 2) or with cirrhosis (Ishak's score > 4). On the contrary, in univariate analysis on patients aged < or = 50 years, male gender was nearly significantly (P = 0.06) predictive of liver fibrosis, whereas it was not in patients > 50 years. Hepatic iron grading, along with age, was an independent factor associated with fibrosis. Moreover, the values of all the variables which describe iron status were significantly higher in males aged < or = 50 years in comparison with females of the same age., Conclusions: In chronic hepatitis C, male gender may be predictive of liver fibrosis only in patients aged < or = 50 years. Among fibrogenetic factors hidden by gender, iron status could play a major role.

Background/aims: In patients with chronic hepatitis C, hepatic iron concentration correlates with liver fibrosis. However, it is not clear whether this correlation merely reflects the presence of more active disease, or iron exacerbates chronic hepatitis C virus (HCV)-induced damage through activation of hepatic stellate cells and regeneration of hepatocytes., Materials and Methods: We studied 72 HCV-positive patients, staged according to the Ishak's score system. We measured hepatic iron concentration with spectrophotometry and evaluated the number of hepatic stellate cells (using monoclonal antibody against alpha smooth muscle actin) and proliferating hepatocytes (using monoclonal antibody against Ki67). Iron and ferritin serum levels were also determined., Results: Hepatic iron concentration correlated statistically with ferritin serum level (r = 0.59, P < 0.001), with grading (r = 0.47, P < 0.001) and staging (r = 0.51, P < 0.001) scores for chronic hepatitis in the whole group of patients. Hepatic iron concentration correlated positively with stellate cell number (r = 0.55, P = 0.004) and Ki67-positive hepatocyte number (r = 0.36, P = 0.08) in patients with chronic hepatitis C and low grading score (< 3)., Conclusions: In patients with chronic hepatitis C and low grading score, hepatic iron could play a role in the activation of hepatic stellate cells and in the progression of fibrosis.

Aim: To evaluate the prevalence of iron overload in chronic hepatitis C and its relationship with liver histology., Patients and Methods: Serum iron, unsaturated iron binding capacity and ferritin levels were determined in 204 consecutive anti-hepatitis C virus positive subjects, whereas hepatic iron concentration, hepatic histological grading and staging, hepatitis C virus genotypes were further assessed in a subgroup of 50 patients who underwent liver biopsy for chronic hepatitis., Results: An increase in the serum markers of iron metabolism was more frequently found in subjects with aminotransferase activities above the normal range, whereas hepatic iron overload, established by direct hepatic iron determination, was found only in 9/50 (18%) patients with chronic hepatitis C. No serum iron marker could reliably predict hepatic iron stores. Patients with mild iron overload usually showed active hepatitis and fibrosis, whereas iron overload was not present in patients without fibrosis or with very mild fibrosis. Two out of nine patients with iron overload were shown to be beta thalassaemia heterozygous, and two were heterozygous carriers of a putative haemochromatosis gene mutation (His63Asp)., Conclusions: Many anti-hepatitis C virus positive patients with elevated aminotransferase activities have serum ferritin levels above the normal range, but only a minority of patients with chronic hepatitis C have a mild iron overload. In chronic hepatitis C, a relationship does exist between hepatic iron content and liver fibrosis.
