This new classification highlights the importance of assessing and identifying the dynamic changes in the quality of fibrosis, especially relevant in the era of antiviral therapy.(Hepatology 2017;65:1438-1450).
Our data indicate that hepatic steatosis is more frequently present in CHB patients than in the general population. We hypothesize that steatosis in CHB patients may be due to metabolic factors and the ability of HBV to indirectly facilitate the development of steatosis. In the present study, steatosis in CHB patients was not found to be associated with the severity of fibrosis.
Background and Aim: Liver stiffness measurement (LSM) using transient elastography (FibroScan) is a useful tool to assess fibrosis in various chronic liver diseases. However, studies were mainly performed in Western countries and largely focused on chronic hepatitis C (CHC). We therefore carried out a multicenter study to validate the accuracy of LSM in the assessment of liver fibrosis in a large cohort of Chinese patients with chronic hepatitis B (CHB). Methods: We compared LSM results to histological staging and serum fibrosis markers (five direct markers, APRI and FIB-4) using Spearman correlation analysis and area under receiver operating characteristic (ROC) curves (AUROCs). Results: Four hundred sixty-nine patients were enrolled and eligible for statistical analysis. LSM in F0 to F4 was 5.5 ± 1.7, 5.8 ± 2.2, 7.6 ± 3.4, 14.5 ± 10.8, and 22.3 ± 13.6 kPa, respectively (correlation with fibrosis stage r = 0.522, P < 0.001). AUROC for LSM to correctly allocate patients to histological fibrosis stage ≥ F2, ≥ F3, and F4 was 0.82, 0.88, and 0.90, respectively. LSM outperformed serum fibrosis markers for detection of fibrosis F ≥ 2 and F4. Patients with ALT levels 1-5x and > 5x the upper limit of normal values had significantly higher stiffness values than stage-matched patients with normal alanine aminotransferase. Conclusion: Transient elastography is a reliable noninvasive technique to predict significant liver fibrosis in Chinese patients with CHB, being superior to current biomarker panels. However, enhanced inflammatory activity can lead to elevated stiffness values unrelated to histological fibrosis stage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
