Objectives: To verify the value of indirect scrum markers in the non-invasive assessment of liver fibrosis in patients with persistently normal or near normal alanine aminotransferases levels (NALT). Design and methods: Forty HCV RNA positive, untreated patients with NALT (30 non-drinkers) underwent two liver biopsies, with a median interval of 78.5 months. The AST/ALT ratio, age-platelet index, AST to platelet ratio index (APRI), Foms fibrosis index and Bonacini's discriminant score were simultaneously determined. Results: In 19 patients, worsening of fibrosis was observed at the second biopsy in comparison to the index biopsy. Among non-drinkers, an APRI > 0.4 had a 100% sensitivity in identifying subjects with significant liver fibrosis (Ishak staging score > 2) and an APR <= 0.4 had a 100% negative predictive value in excluding significant liver fibrosis. Conclusions: APRI performs better, in comparison to all other markers, in correctly classifying patients with NALT with no progression to significant liver fibrosis.
