ARTICLE HIGHLIGHTS
Research background

Transient elastography (TE) can reliably stage liver fibrosis via liver stiffness measurement (LSM) in chronic liver disease. However, the accuracy of TE for assessment of liver fibrosis in patients with autoimmune hepatitis-primary biliary cholangitis (AIH-PBC) overlap syndrome is still unclear.

Research motivation

It is important to identify non-invasive markers of liver fibrosis to predict disease progression.

Research objectives

We evaluated the performance and usefulness of TE for detection of fibrosis in these patients and compared TE with other non-invasive diagnostic tools.

Research methods

The diagnostic accuracy of LSM for the prediction of fibrosis stages was calculated using a receiver operator characteristic (ROC) curve. Optimal LSM cut-off values for F2-4 fibrosis were determined based on the highest combined sensitivity and specificity.

Research results

TE can accurately detect hepatic fibrosis as a non-invasive method in patients with AIH-PBC overlap syndrome.

Research conclusions

For the first time, the current study evaluated TE as a non-invasive assessment of liver fibrosis in patients with AIH-PBC overlap syndrome and demonstrated that it was a reliable tool that was superior to serum biomarker scores for predicting severe fibrosis.

Research perspectives

The impact of hepatic inflammation on LSM values was not analyzed due to the relatively small number of patients in each subgroup. Larger studies are needed to confirm these results.
