Diagnostic criteria for autoimmune liver disease

The diagnostic criteria of autoimmune liver disease are immunological examination, liver biochemical examination, imaging examination, etc. The specific analysis is as follows:

1. Immunological examination

generally examines antibodies in blood. If the examination results are anti-smooth muscle antibodies, anti-nuclear antibodies and IgG levels are elevated, autoimmune hepatitis can be diagnosed; The result of examination is anti-mitochondrial antibody and IgM level is increased, which can be diagnosed as primary biliary cholangitis; the result of examination is IgG4-related hepatobiliary disease.

2. Liver biochemical examination

usually checks the contents of aspartate aminotransferase, serum alkaline phosphatase, alanine aminotransferase, glutamyl transferase, etc. in blood. If the examination results are elevated serum alkaline phosphatase and glutamyl transferase, it can be diagnosed as primary sclerosing cholangitis and primary biliary cholangitis. Examination results for aspartate aminotransferase and alanine aminotransferase elevated, can assist in the diagnosis of autoimmune hepatitis.

3, imaging examination

by endoscopic retrograde cholangiopancreatography results for intrahepatic and extrahepatic bile duct segmental dilatation and stenosis, bead-like changes, can be diagnosed as primary sclerosing cholangitis.
