Latest revision as of 20:54, 7 September 2022
Background
- Autosomal recessive
- Impairment of biliary cellular copper excretion with accumulation in organs (mostly liver, brain, cornea)
- Liver becomes cirrhotic with ~5% developing liver failure
Clinical Features
- Hepatic
- Kayser-Fleischer rings (highly specific)
- Asymptomatic (steatosis, chronic hepatitis, compensated cirrhosis)
- Abdominal pain (acute liver failure/hepatitis)
- Jaundice, hepatomegaly, splenomegaly, ascites
- Upper GI bleeding; sequela of cirrhosis with varices
- Neurologic symptoms
- Dysarthria
- Gait abnormalities
- Dystonia
- Tremor
- Parkinsonism
- Psychiatric symptoms
- Depression, personality changes, impulsiveness, psychosis
Differential Diagnosis
Hepatic Dysfunction
Infectious
- Hepatitis
- Malaria
- HIV (present in 50% of AIDS patients)[1]
- EBV
- Babesiosis, leptospirosis
- Typhoid
- Hepatic abscess, amebiasis
Neoplastic
Metabolic
Biliary
- Biliary cirrhosis
Drugs
- Alcoholic cirrhosis
- Alcoholic hepatitis
- Hepatotoxic drugs
Miscellaneous
- Other causes of cirrhosis
- Autoimmune hepatitis
- Veno-occlusive disease
- CHF (right heart failure)
Neuro/psychiatric symptoms
- Essential tremor
- Parkinson's disease
- Generalized dystonia
- Primary psychiatric disorder (e.g. depression, bipolar disorder, schizophrenia
- Dementia
- Drug abuse
Evaluation
Workup
- LFTs to assess ALT/AST
- CBC to assess for anemia (followed by testing for Coombs-negative hemolytic anemia)
- Ocular slit-lamp to assess for Kayser-Flesicher rings
Diagnosis
- Outpatient ceruloplasmin concentration, serums copper concentration, 24-hour urinary copper excretion +/- genetic testing can be done to confirm diagnosis
Management
- Potent chelators: D-penicillamine (first-line), trientine (second-line), oral zinc
- Low-copper diet
Disposition
- Hepatology consult should be made for follow up
- Screening for hepatocellular carcinoma (HCC) recommended but unclear association
