Chronic Liver Disease Flashcards
What are the clinical features of uncomplicated chronic liver disease?
- Palmar erythema
- Dupytren’s
- Loss of axillary hair
- Gynaecomastia
- Spider naevii
How should CLD be presented?
Signs of CLD
- ? Any sign of portal hypertension
- ?any sign of decompensation
- Size of liver - can be large or small in cirrhosis depending on stage
What are the clinical features of portal hypertension? (2)
- Caput medusa
- Splenomegaly
What are the clinical features of chronic liver disease decompensation? (4)
- Jaundice
- Ascites
- Encephalopathy - constuction dyspraxia (can they draw a 5 point star)
- Aterixis
What are the causes of hepatomegaly/chronic liver disease? 3 Cs 4 Is
Cirrhosis - alcoholic or fatty (body size)
Cancer - HCC (cachexia)
Congestive - congestive cardiac failure or Budd-Chiari (look for fluid overload)
Infective - hepatitis
Immune - PSC, PBC, autoimmune
Infiltrative - amyloid or myeloproliferative
Iron - haemochromatosis (tan or slate grey)
alpa 1
methotrexate
Wilson’s
What investigations should be done in CLD/ hepatomegaly? (6)
- Bloods including:
- FBC and U&E
- LFTs (ALT:AST 2:1 - alcohol)
- Clotting
- Iron and ferritin
- Albumin
- Glucose
- AFP for HCC - Hepatitis and HIV screen
- USS liver with doppler - fibroscan and portal vein
- Ascitic tap if iascites
- Liver biopsy - transjugular if ascites present
- Endoscopy
What tests should be done on ascitic fluid? (4)
- Protein:creatinine ratio >1.1g/L
- If raised suggests a systemic cause such as cirrhosis or CCF, Budd Chiari, nephrotic
- If low suggests malignancy, TB or pancreatitis - Cytology can look for malignancy
- WCC >250 = Spontaneous Bacterial Peritonitis - Amylase can look for pancreatitis
- CS&U for infection
What are the 4 categories for causes of ascites?
- Vascular
- Low albumin
- Peritoneal
- Miscellaneous
What are the 4 vascular causes of ascites?
- Portal hypertension
- Budd-Chiari
- CCF
- Constrictive pericarditis
What are the 2 causes of low albumin ascites?
- Nephrotic syndrome
- Protein losing enteropathy
What are the 3 peritoneal causes of ascites?
- Meig’s syndrome (benign ovaran tumour + ascites + plueral effusion)
- Infection e.g. TB, fungal
- Malignancy (GI, ovarian)
How is ascites managed? (5)
- Fluid restriction
- Diuresis
- Drain (discomfort, CVS compromise)
- TIPs
- Transplant
Which scores can be used to prognositcate cirrhosis? (2)
- Child-Pugh
- MELD (Mortality for End-stage Liver Disease)
What is included int he Child Pugh score? AABIE
AABIE
Ascites
Albumin
Bilirubin
INR
Encephalopathy
What is included in the MELD score?
- Dialysis (2/7) or CVVHD (1/7)
- Creatinine >400
- Bilirubin
- INR
- Sodium
What is cirrhosis?
Late hepatic fibrosis causing distorition of the hepatic architecture, necorsis, regenerative nodules
What are the complications of cirrhosis? (2)
- Portal hypertension
- Hepatocellular carcinoma
What is primary billiary cirrhosis?
immune system attacks the small bile ducts (canals of hering, interlobar)
Causes cholestasis
Back pressure and disease process leads to fibrosis -> cirrhosis and failure - portal hypertension
What are the features of primary billiary cirrhosis? (6)
- Raised bilirubin - jaundice, pruritis
- Raised cholesterol - xanthalasmus, corneus arcus, ACS/CVD
- Malabsorption and steatorrhoea
- Fatigue
- Abdo pain
- Liver failure
What risk factors are associated with PBC? (2)
- Other autoimmune e.g. crohn’s, coeliac, RA,
- Female, young
What are the investigations for PBC? (4)
- Bloods - raised ALP, later raised bilirubin, ESR, IgM
- anti-mitochondrial and ANA
- USS liver
- Liver biopsy for staging
How is PBC managed? (4)
- Ursodeoxycholic acid reduced cholesterol absorption
- Colestyramine - bile acid sequestration
- Liver transplant
- Immunsupression e.g. steroids
What are the complications of cirrhosis?
- Portal hypertension
- Hepatocellular carcinoma
What is primary sclerosing cholangitis?
The intra hepatic and extra hepatic bile ducts become inflamed, strictured and fibrotic
Cholestasis
Backpressure into the liver hepatitis -> fibrosis -> cirrhosis -> failure
What is PSC linked with?
UC
Young male
Family history
What are the features of primary sclerosing cholangitis?
- Raised bilirubin - jaundice, pruritis
- Raised cholesterol - xanthalasmus, corneus arcus, ACS/CVD
- Malabsorption and steatorrhoea
- Fatigue
- Abdo pain
- Liver failure
What are the investigations for PSC?
- Bloods, LFTs - cholestatic, raised ALP
- Auto-antibodies (not that helpful to diagnose but may guide immunosupression ) p-ANCA, ANA, anti-cardiolipin
- MRCP ?bile duct lesions/strictures
What are the risks of PSC? (5)
- Cholangitis (infection)
- Cholangiocarcinoma
- Colorectal cancer
- Cirrhosis and liver failure
- ADEK vitamin deficiency (fat soluble)
How is PSC managed? (4)
- ERCP -> stenting
- Ursodeoxycolic acid
- Colestyramine (bile acid sequestration)
- Transplant only definitive treatment
