AbstractTo compare the diagnostic utility of serum markers in nonalcoholic fatty liver disease (NAFLD) patients with chronic hepatitis B (CHB).This study enrolled 118 consecutive biopsy-proven NAFLD patients with or without CHB. Fibrosis scores of each marker were compared against histological fibrosis staging. Receiver operating characteristic curve (ROC) analysis helped assess the accuracy of each marker.In patients with both diseases, 12.96% (7/54) had advanced fibrosis on biopsy and aspartate aminotransferase (AST) to platelet ratio index was the best performing marker for predicting advanced fibrosis. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and area under the ROC (95% confidence interval) for AST to platelet ratio index (APRI) were 0%, 93.62%, 0%, 86.27%, and 0.676 (0.524-0.828), respectively. The markers ranked as follows from highest to lowest with respect to their accuracy: APRI; BARD; fibrosis-4; and AST to ALT ratio. In patients without CHB, fibrosis-4 was the best performing marker for predicting advanced fibrosis. The sensitivity, specificity, PPV, NPV, and area under the ROC (95% confidence interval) for fibrosis-4 were 77.78%, 85.45%, 46.67%, 95.92%, and 0.862 (0.745-0.978), respectively.Serum markers are less reliable in predicting advanced fibrosis in NAFLD patients with CHB; APRI is the most accurate predictor of the absence of advanced fibrosis.Copyright © 2021 the Author(s).
