Abstract
Significant liver fibrosis is recognized as the key link of therapy and prognosis in patients with chronic hepatitis B infection (CHB). The present study is designed to estimate the benefits of FibroScan (FS) in diagnosing significant fibrosis in patients with CHB. Two hundred and eight consecutive CHB patients, who underwent liver biopsy, FS and laboratory tests, were recruited. The receiver operating characteristic (ROC) curves were generated to assess the performance of non-invasive models. Liver stiffness measurement (LSM) and aspartate transaminase (AST) to platelet (PLT) ratio index (APRI), but not age-platelet index (API) or AST to alanine aminotransferase (ALT) ratio (AAR), were closely correlated with significant fibrosis; areas under ROC curves (AUROC) were 0.817 (p < 0.001), 0.705 (p = 0.003), 0.626 (p = 0.065) and 0.631 (p = 0.055), respectively. When combining LSM with APRI, the AUROC was 0.813, p < 0.001. FibroScan can predict the presence of significant liver fibrosis, so as to avoid liver biopsy. It seems that the combination of FS and APRI does not significantly improve the ability to predict significant fibrosis.
