Abstract

To assess the role of transforming growth factor-beta1 (TGF-beta1), vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in the pathogenesis of fibrosis associated with chronic hepatitis C (CHC) and to evaluate the influence of the antiviral therapy on above parameter levels depending on the treatment results (complete response or no response). Study group included 100 patients with CHC, in whom fibrosis in liver specimens was assessed (Scheuer fibrosis score: 1-4 points). Control group included 30 subjects with antibodies anti-HCV present and persistently normal ALT level, without fibrosis (Scheuer fibrosis score: 0 points). Concentration of studied parameters was assayed in the serum by immunoenzymatic method before and after the therapy with interferon alpha-2b and ribavirin. TGF-beta1 levels were significantly higher in the study group compared to the control group (35.89 vs 32.37 ng/mL; P=0.023). Such differences were not found in VEGF and bFGF levels. In patients showing complete response (negative HCV RNA and normal ALT level), significant increase in VEGF (112.8 vs 315.03 pg/mL; P<0.05) and bFGF (2.51 vs 15.79 pg/mL; P=0.04) levels were found. Significant decrease in TGF-beta1 level was ob...Continue Reading
