AbstractLiver steatosis could affect the accuracy of FibroScan in patients with chronic hepatitis B (CHB) and nonalcoholic fatty liver disease (NAFLD). This study aimed to assess the accuracy and cut-off values of FibroScan for diagnosing liver fibrosis and cirrhosis in patients with concomitant CHB and NAFLD.A total of 116 patients with concomitant CHB and NAFLD who underwent FibroScan test and liver biopsy were retrospectively enrolled. Liver fibrosis was staged according to the METAVIR scoring system. Calculations of the areas under receiver-operating characteristic curves (AUROC) were performed and compared for the staging of liver fibrosis.The AUROCs for FibroScan, gamma-glutamyl transpeptidase to platelet ratio (GPR), aspartate aminotransferase to platelet ratio index (APRI), fibrosis index based on 4 factors (FIB-4), and NAFLD Fibrosis Score (NFS) were 0.87, 0.73, 0.69, 0.57, and 0.57 for the diagnosis of significant liver fibrosis (METAVIR ≥ F2); 0.89, 0.77, 0.75, 0.68, and 0.60 for severe liver fibrosis (METAVIR ≥ F3); and 0.94, 0.86, 0.80, 0.74, and 0.63 for cirrhosis (F4), respectively. The cutoff values of FibroScan for staging liver fibrosis with sensitivity at least 90% were: 8.0 kPa for significant liver fibrosis, and 10.5 kPa for cirrhosis. The cutoff values of FibroScan for staging liver fibrosis with specificity at least 90% were: 10.8 kPa for significant liver fibrosis, and 17.8 kPa for cirrhosis.FibroScan provides high value for the diagnosis of liver fibrosis and cirrhosis in patients with concomitant CHB and NAFLD.
