Abstract

High levels of profibrinogenic cytokine transforming factor beta TGF-β, metalloprotease MMP2, and tissue inhibitor of matrix metalloprotease 1 TIMP1 contribute to fibrogenesis in hepatitis C virus HCV infection and in alcohol-induced liver disease ALD. The aim of our study was to correlate noninvasive serum markers in ALD and HCV patients with various degrees of inflammation and fibrosis in their biopsies. Methods. Serum cytokines levels in HCV-infected individuals in the presence or absence of ALD were measured. Student-s-t-test with Bonferroni correction determined the significance between the groups. Results. Both tumor-necrosis-factor- TNF-α and TGF-β levels increased significantly with the severity of inflammation and fibrosis. TGF-β levels increased significantly in ALD patients versus the HCV patients. Proinflammatory cytokines’ responses to viral and-or toxic injury differed with the severity of liver inflammation. A combination of these markers was useful in predicting and diagnosing the stages of inflammation and fibrosis in HCV and ALD. Conclusion. Therapeutic monitoring of TGF-β and metalloproteases provides important insights into fibrosis.
