BACKGROUND Autoimmune hepatitis (AIH) is an immune-mediated chronic liver disease that can lead to severe fibrosis and cirrhosis. Transient elastography (TE, FibroScan) can assess the fibrotic stages of chronic liver diseases by liver stiffness measurement (LSM). Studies on the diagnostic accuracy of FibroScan for the detection of fibrosis in AIH patients are still limited. MATERIAL AND METHODS This study enrolled 108 AIH patients who underwent liver biopsies. Using the METAVIR scoring system as the reference, Spearman's rank correlation was performed to explore the relationship between the markers and stages of fibrosis. The area under the receiver operating characteristic curve (AUROC) was used to evaluate the diagnostic accuracy. The optimal LSM cut-off values for predicting the stages of fibrosis were calculated. RESULTS LSM was superior to other non-invasive markers in differentiating the stages of fibrosis in AIH patients. AUROC value of LSM was 0.885 for stage F2, 0.897 for stage F3, and 0.878 for stage F4. The optimal LSM cut-off value was 6.27 kPa for stage F2, 8.18 kPa for F3, and 12.67 kPa for F4. CONCLUSIONS FibroScan is a valuable non-invasive method for the evaluation of liver fibrosis of AIH patients.
