A combination of LSM ≥ 7.0 kPa and Mac-2 binding protein glycosylation isomer ≥ 1.00 cut-off index could predict late-stage PBC (i.e. moderate to advanced disease progression) with a sensitivity of 0.58, specificity of 0.82, and accuracy of 0.74.
A glycoproteomics study aimed at identifying such markers discovered Mac 2-Binding Protein Gylcan Isomer (M2BPGi), which is a reliable marker for assessing liver fibrosis in patients with viral hepatitis and other fibrotic liver diseases such as primary biliary cholangitis, biliary atresia, autoimmune hepatitis, and nonalcoholic fatty liver disease.
