Background/Aims: Chronicity of inflammation or fibrosis of liver parenchyma in patients with hepatitis C virus infection can be related to features of immunological responses in the liver. Adhesive interactions and free radicals are two important aspects of this inflammatory response. The aim of this study was to investigate serum sICAM-1 and nitric oxide levels in the sera of patients with post-hepatitis C chronic hepatitis. Methodology: Twenty chronic hepatitis patients diagnosed histopathologically and positive for anti-hepatitis C virus antibody and 20 healthy carriers of hepatitis C virus were included as study and control groups, respectively. Serum hepatitis C virus-RNA, sICAM-I, nitric oxide, blb, albumin and ALT determinations were made in the specimens of each subject in the study and control group. Results: The mean serum sICAM-I levels of study and control subjects were 463.85±20.42ng/mL and 241.85±13.71ng/mL, respectively (p<0.01). The same values for nitric oxide levels were 53.57± 3.63pmol/L and 32.17±2.19μmol/L in the same order and also significantly different from each other (p<0.01). There was a close correlation between fibrosis scores and serum sICAM-I levels (r=0.77, p<0.001), serum albumin (r=-0.54, p=0.014) and ALT (r=0.49, p=0.02). Nitric oxide levels, on the other hand, negatively correlated with fibrosis scores (r=-0.59, p=0.006), sICAM-1 (r=-0.57, p=0.009) and ALT (r=-0.54, p=0.013). Conclusions: Increased serum levels of sICAM are associated with increased fibrotic changes of patients with hepatitis C virus infection, whereas, nitric oxide which may be a suppressor molecule for fibrosing levels are inversely related to fibrotic process.
