Cirrhosis Flashcards
(29 cards)
Define cirrhosis
End stage of chronic liver damage w/ replacement of normal liver architecture w/ diffuse fibrosis & nodules of regenerating hepatocytes
Decompensated cirrhosis if complicated by:
4
Ascites
Jaundice
Encephalopathy
GI bleed
Decompensated cirrhosis can be precipitated by:
8
Infection GI bleed Constipation High protein meal Electrolyte imbalance Alcohol & drugs Tumour development Portal vein thrombosis
Causes of cirrhosis
9
Chronic alcohol misuse Chronic viral hepatitis (Hep B/C) Autoimmune hepatitis Drugs (e.g. methotrexate, hepatotoxic drugs) Inherited Vascular Chronic biliary diseases (PBC, PSC, biliary atresia) Unknown (5-10%) Non-alcoholic steatohepatitis (NASH
Causes of cirrhosis - inherited
5
α1-antitrypsin deficiency Haemochromatosis Wilson’s disease Galactosaemia Cystic fibrosis
Causes of cirrhosis - vascular
2
Budd-Chiari syndrome
Hepatic venous congestion
NASH associated w/
6
obesity diabetes total parenteral nutrition short bowel syndromes hyperlipidaemia drugs (e.g. amiodarone, tamoxifen)
Epidemiology of cirrhosis
death, most common cause UK + world
1 of the top 10 causes of death world wide
Most common cause in UK - chronic alcohol misuse
Most common cause worldwide - chronic viral hepatitis
Presenting symptoms of cirrhosis
4 categories
Early non specific
Due to decreased liver synthetic function
Due to reduced detoxification function
Due to portal hypertension
Presenting symptoms of cirrhosis - early non specific
5
Anorexia Nausea Fatigue Weakness Weight loss
Presenting symptoms of cirrhosis - decreased liver synthetic function
(3)
Easy bruising
Abnormal swelling
Ankle oedema
Presenting symptoms of cirrhosis - reduced detoxification function
(5)
Jaundice Personality change Altered sleep pattern Amenorrhoea Galactorrhoea
Presenting symptoms of cirrhosis - portal hypertension
3
Abdominal swelling
Haematemesis
PR bleeding or melaena
Signs of cirrhosis on physical examination
16
Asterixis Bruises Clubbing Dupuytren’s contracture Palmar erythema Jaundice Gynaecomastia Leukonychia Parotid enlargement Spider naevi Scratch marks (from cholestatic pruritus) Ascites Enlarged liver Testicular atrophy Caput medusae Splenomegaly
Investigations for cirrhosis
7
Bloods Investigations to determine cause Ascitic tap Liver biopsy Imaging Endoscopy Child-Pugh grading
Investigations for cirrhosis - bloods
4
FBC low platelets & Hb LFTs may be normal but often: high AST, ALT, ALP, GGT, bilirubin & low albumin Clotting prolonged PT Serum AFP raised in chronic liver disease high levels may suggest hepatocellular carcinoma
Investigations for cirrhosis - cause
6
Viral serology α1-antitrypsin Caeruloplasmin (Wilson’s disease) Iron studies - serum ferritin, iron, total iron binding capacity TIBC (for haemochromatosis) Anti-mitochondrial antibody (PBC) ANA, ASMA (autoimmune hepatitis)
Investigations for cirrhosis - ascitic tap
4
MC&S - check for infection
Biochem (protein, albumin, glucose, amylase)
Cytology
Neutrophils >250/mm^3 = spontaneous bacterial peritonitis (SBP)
Investigations for cirrhosis - liver biopsy
4
Performed percutaneously or transjugular (if totting deranged or ascitic)
Histopathological features of cirrhosis
periportal fibrosis
loss of normal liver architecture
nodular appearance
Grade - indicates degree of inflammation
Stage - degree of architectural distortion (mild portal fibrosis —> cirrhosis)
Investigations for cirrhosis - imaging
3
US, CT, MRI
To detect complications e.g.: ascites, HCC, hepatic/portal vein thrombosis, exclude biliary obstruction
MRCP (if PSC suspected)
Investigations for cirrhosis - endoscopy
To examine varices
Investigations for cirrhosis - Child-Pugh grading
8
= score for estimating prognosis in chronic liver disease/cirrhosis
Based on: Albumin Bilrubin PT Ascites Encephalopathy
Class A = 5-6
Class B = 7-9
Class C = 10-15
Management of cirrhosis - general
5
Treat cause if possible Avoid alcohol, sedatives, opiates, NSAIDS & drugs that affect liver Nutrition important Enteral supplements should be given NG feeding may be indicated
Management of cirrhosis - complications (encephalopathy)
4
Treat infections
Exclude GI bleed
Lactulose & phosphate enemas
Avoid sedation
