Wilsons disease Flashcards
define Wilsons disease
excessive accumulation of copper In the body and tissues
what are the causes of Wilsons disease ?
- autosomal recessive mutation of ATP7B copper binding protein on chromosome 13
— therefore reduced removal of copper in liver
— therefore excess body copper
what are the risk factors for Wilsons disease?
- family history
-male - 5-35
describe the pathology behind Wilsons disease
- impaired Cu biliary excretion and normal transport bound to Ceruloplasmin.
- Cu accumulates in liver + CNS ( basal ganglia)
what are the three types of symptoms of Wilsons disease?
- Hepatic
- Neurological
- Opthalomogical
what are the hepatic symptoms for Wilsons disease?
- liver disease e.g jaundice
what are the neurological symptoms for Wilsons disease?
- parkinsonism
- memory issues
- dystonia
-dysarthia
what are the opthalomogical symptoms for Wilsons disease?
- kayser- Fleisener ring
( copper deposits in cornea)
how is Wilsons disease diagnosed?
- Cu tests
- liver biopsy
- MRI brain
- 24- hour urine Cu assay ( high)
in Wilsons disease : what would copper tests show?
- Low serum copper ( more copper in tissue, not blood)
-low Ceruloplasmin
in Wilsons disease : what would a liver biopsy ( GS) show?
- high Cu
- Hepatitis
in Wilsons disease : what would a MRI of the brain show?
- cerebellar and Basal Ganglia degeneration
what is the treatment for Wilsons disease?
1st line- D-Penicillamine ( cu chelation)
- diet changes, avoid shellfish and mushroom
- last resort– liver transplant
