摘      要：AIM: Transforming growth factor (TGF)-β1, metalloproteinase (MMP)-1 and its tissue inhibitor (TIMP)-I are considered predictive biomarkers of chronic hepatitis activity and *** aim of this study was to evaluate the effect of lamivudine treatment on the plasma levels of these peptides in patients with chronic hepatitis ***: TGF-β1, MMP-1 and TIMP-1 plasma concentrations were measured with an enzyme immunoassay in 40 patients treated with lamivudine for 48 wk. Elimination of HBV-DNA and HBV antigens was evaluated 24 wk after treatment ***: Baseline TGF-β1(29.6±2.2 ng/mL) and TIMP-1(1 578±93 ng/mL) significantly exceeded normal values(18.3±1.6 ng/mL and 1 102±67 ng/mL respectively). Lamivudine treatment resulted in a significant decrease of TGF-β1 and TIMP-1 during treatment with an increase after 24 wk of treatment. Pretreatment MMP-1 levels (6.7±0.7 ng/mL) were significantly lower than normal values (11.9±0.9 ng/mL) and increased during treatment and follow-up. A significant correlation was noted between TGF-β1 or TIMP-1 and aminotransferases as well as fibrosis scored in liver biopsy specimens. There were no statistically significant differences of TGF-β1, TIMP-1 and MMP-1 between four groups at baseline, 24 and 48 wk of treatment. TGF-β1 and TIMP-1 levels increased significantly in non-responders and normalized in responders at wk 72. MMP-1 also normalized in responders and decreased to values significantly lower than normal in ***: These findings support the role of TGF-β1,TIMP-1 and MMP-1 in the pathogenesis of chronic hepatitis *** of their association with hepatic injury and antiviral treatment efficacy, determination of these peptides may be useful in disease management.
