What is the most common cause of abnormal LFTs in the UK?

Features of NAFLD?
- Usually asymptomatic
- May cause non-specific symptoms (e.g. fatigue, malaise, abdominal discomfort)
- Risk factors present (metabolic syndrome)
- Deranged LFTs for >3 months
Initial management of NAFLD?
Conservative (e.g. weight loss)
What is the medical and surgical management of NAFLD?
- Medical: refer to specialist for vitamin E or pioglitazone if fibrosis
- Surgical: consider transplant in advanced disease
Investigation for NAFLD?
- Non-invasive liver screen
- Liver USS
- Enhanced liver fibrosis blood test to assess for fibrosis
Progression of alcoholic fatty liver disease?
1) Alcohol related fatty liver
2) Alcoholic hepatitis
3) Cirrhosis
What are the stigmata of chronic liver disease?
- Reduced liver function: jaundice and bruising

- Chronic liver disease: spider naevi, palmar erythema, asterixis, gynaecomastia
Bloods findings in alcoholic fatty liver disease?
- Elevated PT
- Raised MCV
- Rise in AST:ALT>2:1
- Raised GGT
What is the AST:ALT elevation pattern seen in AFLD?
2:1
Gold standard investigation for alcoholic fatty liver?
Liver biopsy
Management of alcoholic fatty liver disease?
- Alcohol cessation + thiamine supplement
- Steroids
- Treat complications of cirrhosis
- Liver transplant in severe disease (must be abstinent of 3 months)
What is used to determine benefit of steroid use in acute episodes of alcoholic hepatitis?
Maddrey’s fulminant (score >32)
Obesity/T2DM with abnormal LFTs might suggest?
Non-alcoholic fatty liver disease
What is Maddrey’s fulminant based on?
Bilirubin and PT
What are the complications of alcoholic fatty liver disease?
- Increased risk of breast, throat, oral and liver cancer
- Alcoholic liver disease
- Liver cirrhosis (+ further complications of alcoholic hepatitis)
- Alcohol dependence +/- withdrawal (=/- Korsakoff’s syndrome +/- Wernicke’s encephalopathy)
