Slow regression of liver fibrosis presumed by repeated biomarkers after virological cure in patients with chronic hepatitis C.

چکیده
BACKGROUND & AIMS Chronic hepatitis C is both a virologic and fibrotic disease and complications can occur in patients with sustained virologic response (SVR) with residual fibrosis. Due to the limitations of repeated biopsies, no studies have assessed the dynamic of fibrosis before and after treatment. Using biopsy as reference, FibroTest™ has been validated as a biomarker of fibrosis progression and regression, with similar prognostic values. The aim was to estimate the impact of SVR on the dynamic of fibrosis presumed by FibroTest™. METHODS In a prospective cohort, the main end point was the 10-year regression rate of fibrosis, defined as a minimum 0.20 decrease in FibroTest™, equivalent to one METAVIR stage. RESULTS A total of 933 patients with both repeated FibroTest™ and transient elastography were included. At 10 years, among the 415 patients with baseline advanced fibrosis, 49% (95% CI 33-64%) of the 108 SVR had a regression, which was greater than in the 219 non-responders [23% (14-33%; p < 0.001 vs. SVR)] and not lower than in the 88 non-treated [45% (10-80%; p = 0.39 vs. SVR)] patients. In all 171 SVR, cirrhosis regressed in 24/43 patients, but 15 new cirrhosis cases occurred out of 128 patients, that is only a net reduction of 5.3% [(24-15) = 9/171); (2.4-9.8%)]. Four cases of primary liver cancer occurred in SVR [4.6% (0-9.8)], and 13 in non-responders [5.6% (1.5-9.8); p = 0.07]. CONCLUSIONS In patients with chronic hepatitis C, and as presumed by FibroTest™, virological cure was associated with slow regression of fibrosis 10years later, a disappointing 5% decrease in cirrhosis cases, and a remaining 5% risk of primary liver cancer.

Up to 30% of Iranian adult multi-transfused thalassemic patients are infected with hepatitis C virus (HCV) which can intensify the progression of liver disease caused by iron overload in this group of patients. Our aim was to assess the biochemical and virological response of interferon alfa (INF-α) and its safety in thalassemic patients with chronic HCV infection. This trial was a single c...

BACKGROUND Liver biopsy and virological end points are standard references for assessing the effect of viral hepatitis treatments. We aimed to review evidence-based published data of biomarkers that have been validated as non-invasive alternatives to biopsy as end points for HBV and HCV infection trials. METHODS Studies were included if there were at least two repeated estimates of fibrosis p...

Background & Aim: Viral hepatitis has existed since the creation of human. The estimated prevalence of hepatitis is about 3-5%. For patients with chronic hepatitis C and moderate to severe liver fibrosis, antiviral therapy is strongly suggested, while the cases without fibrosis or with mild liver fibrosis are often followed up without receiving antiviral therapy. The purpose of the present s...
