Alcoholic liver disease Flashcards
What is alcoholic liver disease?
Hint; what 3 conditions does it entail?
Alcoholic liver disease is a term that encompasses the liver manifestations of alcohol overconsumption, including;
fatty liver,
alcoholic hepatitis
chronic hepatitis with liver fibrosis or cirrhosis.
What is the aetiology and risk factorsof ALD?
chronic, heavy alcohol ingestion
a constant high alcohol intake for 10-20 years - estimated not absolute
hepatitis C, smokers, obese = higher risk
some genetic predispostion
Hispanic people
females are at higher risk as capacity for alcohol is less!
What are the presenting symptoms
- Right upper abdominal discomfort
- can include epigastric
others;
weight loss/gain
cachexia
fatigue
malnutrition
Fever - low - alcoholic hepatitis no infection
Pruritis - bile salt accumulation - jaundice
Peripheral neuropathy - toxic effect of alcohol
What are the signs
Major;
1. Hepatomegaly;
May be present in patients with alcoholic fatty liver (steatosis) or alcoholic hepatitis
Less common;
- Jaundice
- Splenomegaly
- haematemesis, malaena - gastric irritation
- Telangiectasis;
- there are man forms of this, can include spider naevi,
- infact 3+ spider naevi points to Liver disease - Palmar erythema
- Asterixis
- dupytrens
- clubbing fingers
- gynaecomastia
- Ascites
- Parotid enlargement
Identify appropriate investigations for ALD
Bloods - LFTs
AST, ALT, AKP, Bilirubin - in short they are all high!
- AST and ALT are considered to be 30 units/L for men and 19 units/L for women.
- so the results will exceed this hugely with upper limit of 300. - AST/ALT ratio
The classic ratio of AST/ALT >2 is seen in about 70% of cases - ALP
- normal or elevated
- If elevated may represent cholestasis associated with ALD. - Bilirubin
Both conjugated and unconjugated bilirubin are increased in varying proportion. - GGT
- High. more sensitive than ast but less specific for ALD.
FBC
anaemia, high WCC, thrombocytopenia, high MCV
PT/INR
normal or elevated
Hepatic ultrasound - hepatomegaly, fatty liver etc
more specific tests for the cause;
liver biopsy, hepatitis serology etc
Generate a management plan for alcoholic liver disease
1st line;
Alcohol abstinence + withdrawal management
- Oxezapam. or lorazepam.
Weight loss, smoking stop
Nutritional supplements and multivitamins*
Immunisation
- hep A, B, influenza, pneumococcal
*tend to be thiamine, folic acid, riboflavin (vitamin B2), niacin (vitamin B3), and pyridoxine (vitamin B6) deficient, so given multiviatamins. enteral feeding preferred first over other ways.
2nd line;
Liver transplant
- must be able to demonstrate rehabilitation and sustained abstinence.
What is the meaning of a high bilirubin in lft?
impaired METABOLIC function of liver
in the absence of biliary obstruction
What is the meaning of a low serum albumin?
impaired SYNTHETIC function of liver
