• Women metabolise slower than men
State two effects that alcohol can have on the liver
- Steatosis (fatty liver)
* Steatohepatitis (fatty liver with inflammation)
Describe the features of steatohepatitis
- Neutrophil infiltration

What is the Aspartate Amino Transferase (AAT) test?
AST is found in the highest concentrations in your liver, muscles, heart, kidney, brain and red blood cells. Abnormal levels can be associated with liver injury.
Test measures the amount of AST in your blood that has been released from injured tissue
Describe the lab results your would expect to see in liver disease
- Aspartate Amino Transferase (AAT) > Alanine Amino Transferase (ALT). Ratio > 2
- Raised Gamma Glutamyl Transferase
- Macrocytosis
- Thrombocytopenia (low platelets)
Blood tests not specific to alcohol
What investigations are used in liver disease?
- Labs - AST, AAT, GGT, blood count
* USS fatty liver
What is the pathology behind hepatic encephalopathy?
- Liver failure
* Cannot process toxins properly and so leads to a build up of ammonia
How is hepatic encephalopathy graded?
Graded 1-4:
• 1 - mild confusion
• 4 - coma
Name 5 causes of hepatic encephalopathy
- Infection
- Drugs
- Constipation
- GI Bleed
- Electrolyte disturbance
What is the treatment of hepatic encephalopathy?
• Bowel clear out, lactulose, enemas (constipation cause build-up of toxins from gut causing confusion) • Antibiotics • Supportive: o ITU, airway support o Nasogastric tube for meds
What are three conditions you need to exclude before diagnosing hepatic encephalopathy?
- Infection
- Hypoglycaemia
- Intra-cranial bleed
What is the complication of spontaneous bacterial peritonitis?
Ascites – build-up of fluid in abdomen and there is a risk of it becoming infected
