AIM: To determine factors associated with fibrosis progression in hepatitis C virus (HCV)-infected patients without significant initial pathological lesions.
METHODS: Seventy six untreated HCV-infected patients with initially normal liver as defined by a Knodell score < or = 3, with 2 liver biopsies and detectable HCV-RNA were included. Markers of fibrosis progression were assessed.
RESULTS: Median duration of infection and time between paired biopsies was 13 (95% CI: 1-28) and 4 (95% CI: 2-16) years respectively. Alanine-transaminase (ALT) activity was normal in 43.4% of cases. 50% demonstrated progression of the necro-inflammation and 34% of fibrosis after a median time evolution of 4 years (95% CI: 2-16). The median difference in the necro-inflammation and fibrosis score between biopsies was low, 1.5 and 0.0 respectively. Univariate analysis showed there was no difference between fibrosis activity or evolution according to genotype or viral load. A higher fibrosis progression (P = 0.03) was observed in patients with body mass index (BMI) > 25. Fibrosis progression correlated with the time interval between biopsies (P = 0.01). A significant progression of activity (1.7 vs 0.4, P < 0.05) or fibrosis (0.9 vs 0.0, P 25 and the time interval between 2 biopsies.
CONCLUSION: There is no fibrosis progression in 66% of patients without significant initial histopathological lesion. Fibrosis progression is associated with elevated ALT and BMI > 25.https://www.ncbi.nlm.nih.gov/pubmed/18609710
