Background Aims: Liver biopsy is the gold standard for assessing hepatitis B virus (HBV)-related histology. The aim was to determine the diagnostic utility of noninvasive serum markers in patients with chronic hepatitis B. Methods: The aminotransferases and indices including alpha(2)-macroglobulin, apolipoprotein A1, haptoglobin, gamma-glutamyl-transpeptidase (GGT), and total bilirubin (Fibrotest), and ALT (Actitest) were compared with liver histology. The primary outcomes were A2-A3 activity and F2-F4 fibrosis (METAVIR). Results: Two hundred and nine patients were included. Forty-one patients (20%) had A2-A3 activity and 61 (29%) had F2-F4 fibrosis. AST and GGT (P < 0.001) were independently associated with A2-A3 activity. AST, ALT, and Actitest accurately predicted activity ((areas under receiver operating characteristic (ROC) curves (AUROC), 0.81-0.82 +/- 0.04)); an AST or ALT <= 30 IU/l excluded significant activity with 96% certainty. Fibrotest accurately predicted F2-F4 fibrosis (AUROC, 0.78 +/- 0.04). Fibrotest scores (range, 0-1.0) <= 0.20 and >0.80 had negative and positive predictive values of 92%, respectively. Restricting biopsy to patients with intermediate scores (>0.20 and less than or equal to0.80) may prevent liver biopsies in 46 % of patients while maintaining 92 % accuracy. Conclusions: The aminotransferases and an index including five biochemical markers are accurate noninvasive markers of HBV-related activity and fibrosis, respectively.
