Summary
Definition
History and exam
Key diagnostic factors
- fatigue/malaise
- anorexia
- abdominal discomfort
- hepatomegaly
- jaundice
- encephalopathy
Other diagnostic factors
- pruritus
- arthralgia
- nausea
- fever
- spider angiomata
- gastrointestinal bleeding
- splenomegaly
- ascites
Risk factors
- female sex
- genetic predisposition
- immune dysregulation
- measles virus
- cytomegalovirus
- Epstein-Barr virus
- hepatitis viruses A, C, and D
- certain drugs
Diagnostic investigations
1st investigations to order
- aspartate transaminase
- alanine transaminase
- bilirubin
- gamma glutamyl transferase (gamma-GT)
- alkaline phosphatase
- serum globulin
- serum albumin
- prothrombin time
Investigations to consider
- antinuclear antibodies (ANAs)
- smooth muscle antibodies (SMAs)
- anti-soluble liver antigens or liver/pancreas (anti-SLA/LP)
- perinuclear antineutrophil cytoplasmic antibodies (pANCA)
- antibodies against single-stranded DNA (anti-ssDNA)
- antibodies against double-stranded DNA (anti-dsDNA)
- antibodies to liver/kidney microsome type 1 antigen (anti-KLM-1)
- antibodies to liver/kidney microsome type 3 antigen (anti-LKM-3)
- antibodies to liver cytosol 1 antigen (anti-LC1)
- antimitochondrial antibodies (AMAs)
- antibodies against asialoglycoprotein receptor (anti-ASGP-R)
- IgM antibodies to hepatitis A virus (IgM anti-HAV)
- antibodies to hepatitis B core antigen (anti-HBc)
- hepatitis C antibodies and viral RNA
- ceruloplasmin
- alpha-1 antitrypsin
- serum iron and total iron binding capacity
- thiopurine methyltransferase (TPMT) activity
- abdominal ultrasound
- liver biopsy
Treatment algorithm
acute severe disease
active disease
inactive disease or minimally active disease with comorbidities
AIH-primary biliary cirrhosis overlap syndrome
inadequate response to initial therapy or single relapse: without hepatic decompensation
multiple previous relapses: without hepatic decompensation
decompensated liver disease
