| Popis: | We have evaluated the histological progression of liver disease in 29 untreated patients with chronic hepatitis C. All patients were positive to antibodies to hepatitis C virus by ELISA2 and RIBA2. Two liver biopsies were carried out for each patient, with an interval ranging between 12 and 126 months (mean 50.2±30.7). In all cases the usual histological classification was applied and the histological activity index scoring system according to Knodell et al. was determined. Fifteen cases worsened (51.7%), 12 cases showed no histological changes (41.4%) and two patients improved (6.9%). Cirrhosis was found in five patients (18.5%) in the second liver biopsy. Epidemiological, clinical, biochemical and histological parameters were compared between the group without histological progression and the group with impairment in liver histology. Factors related to histological worsening were: more advanced age (p=0.002), high levels of aspartate aminotransferase (p=0.04), high global histological activity index (p=0.03) and piecemeal necrosis and bridging necrosis scores (p=0.02) at first biopsy. The histological activity index can be applied to assess the natural history of chronic viral hepatitis, and is a good tool to evaluate the prognosis. Thus chronic hepatitis C virus infection is a histologically progressive disease in at least half the cases. |
