Cirrhosis is a late-stage liver disease characterised by extensive scarring of the liver tissue, which interferes with liver function. It is often caused by long-term alcohol abuse, but non-alcoholic causes are also common, such as metabolic dysfunction-associated steatohepatitis (MASH) and hepatitis C infection. Cirrhosis is associated with muscle wasting, also known as sarcopenia, which is a frequent complication of the disease. This condition leads to a progressive and generalised loss of skeletal muscle mass and strength, affecting patients' quality of life and survival rates, even after liver transplantation.

Cirrhosis is a late stage of liver disease, causing scarring in the liver tissue
Cirrhosis is a late stage of liver disease, characterised by scarring in the liver tissue. This scarring is caused by chronic inflammation in the liver, interfering with its ability to function. Alcohol-induced hepatitis is a common cause of cirrhosis, but non-alcoholic causes are also prevalent. Metabolic dysfunction-associated steatohepatitis (MASH), for example, is a non-alcoholic cause of cirrhosis, resulting from excess fat storage in the liver. Other causes include viral hepatitis C and B infections, autoimmune diseases, and chronic inflammation.
Cirrhosis is associated with muscle loss, or sarcopenia, which is a significant complication of the disease. Sarcopenia is defined as the loss of skeletal muscle mass and strength and is observed in 40%-70% of patients with cirrhosis. It is more common in men, with 50% of cirrhotic men and 18% of cirrhotic women exhibiting sarcopenia. Sarcopenia is a major predictor of adverse clinical outcomes, including reduced survival rates, decreased quality of life, and the development of further complications, even after liver transplantation. It is also linked to a higher risk of death from sepsis.
The mechanisms underlying sarcopenia in cirrhosis are complex. Malnutrition is a contributing factor, with poor oral intake and lack of physical activity playing a role. Cirrhosis is considered a state of accelerated starvation, leading to anabolic resistance and impairing the body's ability to utilise nutrients for muscle maintenance and growth. Additionally, metabolic and hormonal alterations, medications, hepatic encephalopathy, and inflammatory cytokines may contribute to muscle loss.
The standard clinical approach to managing sarcopenia in cirrhotic patients involves nutritional supplementation with specific amino acids and calorie-controlled diets. However, nutritional interventions alone have shown limited effectiveness. Physical activity and exercise programs, including progressive resistance training, can help improve muscle function and reduce sarcopenia. Short-term exercise programs of 3 to 6 months, with intervals of two to three times a week, can lead to improvements in muscle mass and strength.

Muscle wasting is a common feature of chronic liver disease, affecting around 40% of cirrhosis patients
Cirrhosis is a late stage of liver disease, characterised by extensive scarring of the liver tissue. This scarring interferes with the liver's ability to function properly. Muscle wasting, or sarcopenia, is a common feature of cirrhosis, affecting around 40% of patients. It is defined as the progressive and generalised loss of muscle mass. Sarcopenia is prevalent in ageing, malignancy, and rheumatoid arthritis. It is also observed in patients with end-stage liver disease, where it can have detrimental effects on survival.
The presence of sarcopenia is a significant predictor of mortality in patients with cirrhosis, independent of the severity of liver dysfunction. Patients with rapid muscle loss are more likely to succumb to liver disease. Sarcopenia is associated with decreased survival rates, lower quality of life, and increased risk of complications from cirrhosis. It can also worsen post-liver transplant outcomes. Approximately 20% of patients awaiting liver transplantation exhibit sarcopenic obesity, a condition characterised by muscle loss and dysfunction accompanied by the pathological accumulation of adipose tissue.
Malnutrition is a common issue in cirrhosis and is closely linked to muscle wasting. Malnutrition can lead to muscle depletion, and cirrhotic patients often experience a decline in skeletal muscle mass. This loss of muscle mass contributes to reduced survival rates and a lower quality of life, even after liver transplantation. The standard clinical approach to addressing malnutrition involves nutritional supplementation to ensure adequate calorie and protein intake. However, supplemental nutrition alone may not improve clinical outcomes in cirrhosis patients as they are believed to be in a state of anabolic resistance, preventing appropriate skeletal muscle responses to nutrient administration.
To assess muscle size in cirrhosis, cross-sectional analytic morphometry using computed tomography (CT) scans or magnetic resonance imaging (MRI) is considered the gold standard for research purposes. These methods provide unbiased evaluations by accounting for fluid accumulation. While CT scans are valuable for research, they are not suitable for routine clinical practice due to their cost and inconvenience. Therefore, there is a need for alternative tools that are cost-effective, user-friendly, and accurate for assessing muscle wasting in clinical settings.

Sarcopenia is a term used to describe the loss of skeletal muscle mass
Cirrhosis is a late stage of liver disease, characterised by extensive scarring of the liver tissue. This scarring interferes with the liver's ability to function properly. Muscle wasting is a common feature of chronic liver disease, and cirrhosis is no exception. It is observed in approximately 40% of patients with cirrhosis.
The loss of skeletal muscle mass due to sarcopenia can be counteracted by resistance-based strength training. Exercise can dramatically slow the rate of muscle loss. Additionally, a healthy diet, particularly one rich in protein, can help reverse the effects of sarcopenia. β-hydroxy β-methylbutyrate (HMB), a metabolite of leucine, has been reported to prevent the loss of lean body mass in older adults. However, there are currently no FDA-approved medications to treat sarcopenia.
Sarcopenia is also observed in patients with cirrhosis. Dr Srinivasan Dasarathy, a hepatologist, observed malnutrition and loss of skeletal muscle mass in patients with end-stage liver disease. Despite muscle loss being the most frequent complication of cirrhosis, it remains understudied. The loss of muscle mass in patients with cirrhosis can impact their survival rates, with mortality being higher in patients with ongoing muscle loss.

Malnutrition is a common feature of cirrhosis, and can lead to muscle loss
Cirrhosis is a late stage of liver disease, characterised by extensive scarring in the liver. This scarring interferes with the liver's ability to function properly. It is often caused by chronic inflammation in the liver, which can be triggered by long-term heavy alcohol use, non-alcoholic fatty liver disease, viral hepatitis, autoimmune diseases, and more.
Malnutrition is a common feature of cirrhosis, affecting approximately 20% to 60% of patients, according to various studies. This is due to the decreased utilisation of nutrients caused by fat malabsorption, bile acid deficiency, portal hypertension, bacterial overgrowth, and the chronic use of lactulose, all of which are complications of cirrhosis. The altered metabolism of carbohydrates and proteins, resulting from insulin resistance, abnormal amino acid metabolism, and increased protein catabolism, can lead to a starvation state. This, in turn, causes muscle loss, also known as sarcopenia or cachexia. Sarcopenia specifically refers to the loss of skeletal muscle mass and function, which is highly prevalent in ageing, malignancy, and rheumatoid arthritis.
The loss of muscle mass is a major predictor of poor clinical outcomes in patients with cirrhosis. It can lead to reduced survival rates, a decreased quality of life, and the development of further complications, even after a liver transplant. In fact, muscle depletion, or muscle wasting, is observed in approximately 40% of patients with cirrhosis. It is assessed using cross-sectional analytic morphometry with computed tomography (CT) scans or magnetic resonance imaging, which are considered the gold standards for research purposes.
The impact of malnutrition and muscle wasting on the survival of patients with cirrhosis has been recognised early on. Nutritional interventions and exercise programmes may help improve muscle wasting and, consequently, survival rates. However, despite aggressive interventions, malnutrition-induced muscle mass loss in cirrhosis may not always be reversible.

Sarcopenic obesity is prevalent in cirrhosis patients awaiting liver transplants
Cirrhosis is a late-stage liver disease characterised by scarring of the liver tissue, which interferes with its ability to function. It is caused by chronic inflammation in the liver, which can be triggered by long-term heavy alcohol use, non-alcoholic fatty liver disease, hepatitis C infection, hepatitis B infection, and autoimmune diseases. Cirrhosis is associated with several symptoms, including unexplained weight loss and muscle loss.
Muscle wasting, or muscle depletion, is a common feature of chronic liver disease, affecting approximately 40% of patients with cirrhosis. It is defined as the progressive and generalised loss of muscle mass, which can be assessed using computed tomography (CT) scans or magnetic resonance imaging. The prevalence of muscle wasting increases with the severity of the disease. Studies have shown that decreased muscle size, as assessed by CT scan, is an independent predictor of mortality in patients with cirrhosis awaiting liver transplantation.
Sarcopenia, a term coined in 1988 by Tufts University clinical nutritionist Irwin Rosenberg, MD, refers to the loss of skeletal muscle mass and function. It is often observed in patients with cirrhosis and is considered a major predictor of poor clinical outcomes, including reduced survival and decreased quality of life, even after liver transplantation. Sarcopenia can occur independently of weight or body mass index (BMI). Approximately 20-35% of patients with cirrhosis experience both significant muscle wasting and the accumulation of body fat, a condition known as sarcopenic obesity.
The management of sarcopenic obesity in cirrhosis patients is challenging due to conflicting advice regarding specific nutritional needs. While some studies advise against weight loss in this population, others propose that nutritional management should follow general guidelines for cirrhosis. However, it is generally agreed upon that excessive energy restriction through very low-calorie diets should be avoided due to the risk of worsening sarcopenia. Nutritional care for these patients should be directed by an expert dietitian experienced in nutritional support for cirrhosis. Additionally, exercise interventions may be considered for patients with a poor general condition, carefully balancing the benefits against the risk of adverse events.
