General Information

The EUROLINE Autoimmune Liver disease profile measures human IgG autoantibodies to 9 different antigens: AMA-M2, M2-3E, Sp100, PML, gp210, LKM-1, LC-1, SLA/LP and Ro-52, in serum or plasma. It is largely used in the diagnosis of autoimmune liver diseases, such as primary biliary cirrhosis, primary sclerosing cholangitis, suspected autoimmune hepatitis or where there is an increase in transaminases for unclear reasons.

Notes

Autoantibody

Clinical Relevance

AMA-M2

Has a prevalence of approximately 85-95% in PBC. It is also seen in 30-96% of overlap-syndrome cases.

M2-3E

Occur with a prevalence of 90-95% in PBC cases. Also found in AIH patients with a prevalence of 4%.

Sp100

Detected in PBC patients with a prevalence of 15-31%.

PML

Associated with PBC (prevalence 13%) and AIH (prevalence 4%).

Gp210

Detected with a prevalence of 26% in PBC and 4% in AIH.

LKM-1

Has a prevalence of around 70% in AIH Type 2.

LC-1

Detected in approximately 10% of AIH Type 1 and 35% of AIH Type 2 patients.

SLA/LP

Found in AIH patients with a prevalence of 15-30% (Europe, North America) and 7% (Japan).

Ro-52

Has a prevalence of 5-19% in AIH. Not specific for autoimmune liver disease and can be found in sera from patients with myositis, SSc and other collagenoses.
