Liver Cirrhosis
Liver cirrhosis is the final stage of chronic liver disease, characterized by diffuse fibrosis and regenerative nodules. Common UK causes include alcohol-related liver disease (ArLD), Metabolic dysfunction-Associated Steatotic Liver Disease (MASLD — formerly NAFLD), and Hepatitis B/C. Management involves treating the underlying cause and complications: Carvedilol (preferred per BAVENO VII) for variceal prophylaxis, diuretics for ascites, and 6-monthly HCC surveillance.
📌 Learning Objectives

- Apply principles of management for compensated and decompensated liver cirrhosis, including treatment of complications.
- Discuss the indications and contraindications for liver transplantation in patients with cirrhosis.
- Recognise the importance of screening for hepatocellular carcinoma in cirrhotic patients.
📋 Overview
Cirrhosis represents irreversible end-stage scarring of the liver. The most common causes in UK clinical practice are Alcohol-related Liver Disease (ArLD), Non-Alcoholic Fatty Liver Disease (NAFLD/MASLD), and Chronic Hepatitis C. Cirrhosis is classified as 'compensated' (asymptomatic) or 'decompensated' (presence of jaundice, ascites, encephalopathy, or variceal bleeding). Portal hypertension develops as fibrosis increases resistance to blood flow through the liver, leading to splenomegaly and portosystemic shunts (oesophageal varices). The Child-Pugh and MELD scores are used to assess prognosis and prioritize for liver transplantation. Clinical signs include spider naevi, palmar erythema, leuconychia, and hepatosplenomegaly. Diagnostic evaluation involves blood tests (low albumin, high bilirubin, prolonged PT/INR), imaging (ultrasound showing a nodular liver), and increasingly, transient elastography (FibroScan). Screening for hepatocellular carcinoma (HCC) with 6-monthly ultrasound and alpha-fetoprotein (AFP) is mandatory for all cirrhotic patients. Management is multifaceted, focusing on smoking/alcohol cessation, sodium restriction for ascites, and beta-blockers for varices.
🔬 Basic Science
The central pathogenetic cell is the hepatic stellate cell (Ito cell). In response to chronic injury and inflammation (from toxins, viruses, or fat), stellate cells are 'activated' and transform into myofibroblast-like cells. These cells secrete excessive amounts of extracellular matrix proteins, specifically Type I and III collagen, into the space of Disse. This leads to the 'capillarization' of the hepatic sinusoids, which destroys the normal exchange between blood and hepatocytes. The shrinking of the liver and the formation of regenerative nodules disrupt the intrahepatic vascular flow, raising portal venous pressure. This portal hypertension leads to the opening of collateral vessels (varices), splenomegaly (due to congestion), and the shift of fluid into the peritoneal cavity (ascites) driven by both high pressure and low oncotic pressure from hypoalbuminaemia.
🏥 Clinical Relevance
Examination signs: Stigmata of chronic liver disease include spider naevi (in the SVC distribution), palmar erythema, gynaecomastia, and testicular atrophy (due to hyperoestrogenism). Dupuytren’s contracture and parotid swelling are often seen in alcoholic cases. Portal hypertension signs: Splenomegaly, caput medusae (peri-umbilical veins), and ascites (shifting dullness). Decompensation signs: Jaundice, encephalopathy (confusion, asterixis), and bruising (impaired clotting factor synthesis). Complications: 1. Ascites: Can lead to Spontaneous Bacterial Peritonitis (SBP), which presents with fever and abdominal pain; neutrophil count >250/mm3 in ascitic fluid is diagnostic. 2. Hepatic Encephalopathy: Driven by toxins (like ammonia) crossing the blood-brain barrier. 3. Oesophageal varices: High risk of catastrophic GI bleeding.
🧪 Investigations
Bloods: LFTs (Low albumin, high bilirubin), FBC (thrombocytopenia from hypersplenism), Coagulation screen (raised PT/INR). Liver screen: Viral serology, Autoantibodies (AMA for PBC, SMA for AIH), Ferritin/Transferrin (haemochromatosis), Alpha-1-antitrypsin. Imaging: Ultrasound (nodular liver, splenomegaly, portal vein flow). FibroScan: Non-invasive assessment of liver stiffness. Ascitic Tap: Mandatory in all new ascites/suspected SBP for WCC, culture, and protein (SAAG score).
💊 Management
**Treat the cause:** Alcohol abstinence (ArLD), antivirals for Hep B/C, weight loss and metabolic risk factor management for MASLD (Metabolic dysfunction-Associated Steatotic Liver Disease — previously NAFLD).
**Portal Hypertension (Variceal Prevention):** Carvedilol (non-selective beta-blocker with additional alpha-1 blocking activity) is now preferred over Propranolol per BAVENO VII 2021 consensus — greater reduction in hepatic venous pressure gradient. Start at 6.25mg BD, titrate to 12.5mg BD if tolerated. Propranolol remains an alternative.
**Ascites:** Low sodium diet (<2g/day), diuretics (Spironolactone first-line, add Furosemide if insufficient). Large volume paracentesis + albumin infusion for tense ascites.
**Spontaneous Bacterial Peritonitis (SBP):** IV Cefotaxime (or Tazobactam/Piperacillin as per local guidelines); IV Albumin 1.5g/kg at diagnosis + 1g/kg on day 3 (reduces hepatorenal syndrome risk). Long-term prophylaxis: Ciprofloxacin/Norfloxacin OD.
**Hepatic Encephalopathy:** Lactulose (titrated to 2-3 soft stools/day) and Rifaximin 550mg BD as secondary prophylaxis.
**HCC Surveillance:** 6-monthly ultrasound + AFP in all cirrhotic patients.
**Liver Transplantation:** For patients with decompensated cirrhosis meeting UKELD criteria (UKELD ≥49 predicts mortality >9% at 1 year).
**Portal Hypertension (Variceal Prevention):** Carvedilol (non-selective beta-blocker with additional alpha-1 blocking activity) is now preferred over Propranolol per BAVENO VII 2021 consensus — greater reduction in hepatic venous pressure gradient. Start at 6.25mg BD, titrate to 12.5mg BD if tolerated. Propranolol remains an alternative.
**Ascites:** Low sodium diet (<2g/day), diuretics (Spironolactone first-line, add Furosemide if insufficient). Large volume paracentesis + albumin infusion for tense ascites.

**Hepatic Encephalopathy:** Lactulose (titrated to 2-3 soft stools/day) and Rifaximin 550mg BD as secondary prophylaxis.
**HCC Surveillance:** 6-monthly ultrasound + AFP in all cirrhotic patients.
**Liver Transplantation:** For patients with decompensated cirrhosis meeting UKELD criteria (UKELD ≥49 predicts mortality >9% at 1 year).

A patient with cirrhosis, abdominal pain, and fever has SBP until proven otherwise. Perform an ascitic tap immediately. Remember: 'Albumin, Bilirubin, Clotting' are the most reliable markers of liver function (synthetic capacity), not the ALT/AST.

Exam Pearls ⌄
⭐ High Yield
Alcohol-related liver disease (ArLD) and MASLD (Metabolic dysfunction-Associated Steatotic Liver Disease, formerly NAFLD) are the most common causes of cirrhosis in the UK.
Portal hypertension is a key complication, leading to varices, ascites, and encephalopathy.
Child-Pugh and MELD scores are crucial for assessing prognosis and transplant eligibility.
Decompensated cirrhosis is defined by the presence of jaundice, ascites, encephalopathy, or variceal bleeding.
Regular surveillance for hepatocellular carcinoma (HCC) with ultrasound and AFP is essential for all cirrhotic patients.
Clinical signs like spider naevi, palmar erythema, and ascites indicate chronic liver disease.
Management involves treating the underlying cause and specific complications, e.g., beta-blockers for varices, diuretics for ascites.
💡 Clinical Pearl
Upper GI Bleeding: Oesophageal varices, a complication of portal hypertension in cirrhosis, are a major cause of upper GI bleeding.
Hepatocellular Carcinoma: Cirrhosis is the strongest risk factor for developing hepatocellular carcinoma, necessitating regular screening.
Spontaneous Bacterial Peritonitis: Patients with ascites due to cirrhosis are at high risk of developing spontaneous bacterial peritonitis, a life-threatening infection.
⚠️ Exam Tip — Common Mistakes
Confusing compensated and decompensated cirrhosis and their management implications.
Underestimating the importance of screening for HCC in all cirrhotic patients.
Failing to recognise the systemic effects of cirrhosis beyond the liver, e.g., coagulopathy, renal dysfunction.
Not appreciating that NAFLD is now a leading cause of cirrhosis, alongside alcohol.
Misinterpreting isolated abnormal LFTs as definitive cirrhosis without further investigation.
