The cirrhosis stage describes the severity of liver cirrhosis. Staging helps doctors assess disease progression and plan the most appropriate treatment.
What Is the Cirrhosis Stage?
The cirrhosis stage refers to how advanced a patient´s liver cirrhosis has become. In liver cirrhosis, healthy liver tissue is progressively replaced by scar tissue (fibrosis), impairing the liver´s ability to function. Accurate staging is essential for guiding treatment decisions, estimating prognosis, and evaluating eligibility for liver transplantation.
Causes of Liver Cirrhosis
Liver cirrhosis can develop from various underlying conditions and risk factors, including:
- Chronic alcohol misuse (alcoholic liver disease)
- Chronic viral hepatitis (hepatitis B or C)
- Non-alcoholic fatty liver disease (NAFLD/NASH)
- Autoimmune hepatitis
- Primary biliary cholangitis (PBC) or primary sclerosing cholangitis (PSC)
- Inherited metabolic disorders such as haemochromatosis or Wilson disease
Classification Systems for Cirrhosis Staging
Several widely accepted systems are used to classify the stage of liver cirrhosis. The two most important are the Child-Pugh Score and the MELD Score.
Child-Pugh Score
The Child-Pugh Score classifies liver cirrhosis into three classes based on five clinical parameters:
- Serum bilirubin level (bile pigment)
- Serum albumin level (blood protein)
- Prothrombin time (clotting function)
- Presence of ascites (fluid accumulation in the abdomen)
- Hepatic encephalopathy (confusion or altered consciousness due to liver failure)
The three classes are:
- Child-Pugh A (5–6 points): Compensated cirrhosis with well-preserved liver function
- Child-Pugh B (7–9 points): Moderately impaired liver function
- Child-Pugh C (10–15 points): Decompensated cirrhosis with severely impaired liver function
MELD Score
The MELD Score (Model for End-Stage Liver Disease) is a numerical score calculated from laboratory values to assess the severity of chronic liver disease:
- Creatinine (kidney function)
- Bilirubin (liver function)
- INR (blood clotting)
- Serum sodium
A higher MELD score indicates a worse prognosis. It is primarily used to prioritise patients on liver transplant waiting lists.
Additional Staging Systems
In clinical research, the Baveno classification is also used, dividing cirrhosis into stages 1 through 5 based on clinical events such as ascites, variceal bleeding, and kidney failure.
Symptoms by Cirrhosis Stage
Symptoms vary considerably depending on the stage of disease:
- Early stage (compensated): Often no symptoms or only non-specific complaints such as fatigue, reduced performance, or mild upper abdominal discomfort
- Advanced stage (decompensated): Jaundice (icterus), ascites, leg oedema, increased bleeding tendency, confusion (hepatic encephalopathy), and dilated blood vessels in the oesophagus (oesophageal varices)
Diagnosis
The diagnosis and staging of liver cirrhosis involves:
- Blood tests (liver enzymes, full blood count, coagulation markers, MELD calculation)
- Abdominal ultrasound, CT scan, or MRI
- Liver biopsy for precise assessment of fibrosis stage (Metavir score F0–F4)
- Elastography (e.g. FibroScan) as a non-invasive method to measure liver stiffness
- Endoscopy to evaluate oesophageal varices
Treatment According to Cirrhosis Stage
Treatment depends on the severity of the disease:
- Compensated stage: Treating the underlying cause (e.g. antiviral therapy for hepatitis, alcohol abstinence), regular monitoring, and a healthy diet
- Decompensated stage: Managing complications such as ascites (diuretics), infections (antibiotics), encephalopathy (lactulose), and variceal bleeding
- End-stage: Evaluation for liver transplantation, which is the only curative treatment option
Prognosis
Prognosis depends critically on the cirrhosis stage. Patients with compensated cirrhosis have a significantly better life expectancy than those with decompensated disease. Without liver transplantation, the one-year mortality rate for Child-Pugh C cirrhosis can reach up to 85%. Early diagnosis and consistent treatment can slow disease progression considerably.
