Background and aimsObesity is frequently associated with cirrhosis, and cirrhotic patients may develop simultaneous loss of skeletal muscle and gain of adipose tissue, culminating in the condition of sarcopenic obesity. Additionally, muscle depletion is characterized by both a reduction in muscle size and increased proportion of muscular fat, termed myosteatosis. In this study, we aimed to establish the frequency and clinical significance of sarcopenia, sarcopenic obesity and myosteatosis in cirrhotic patients.MethodsWe analysed 678 patients with cirrhosis. Sarcopenia, sarcopenic obesity and myosteatosis were analysed by CT scan using the third lumbar vertebrae skeletal muscle and attenuation indexes, using previously validated gender‐and body mass index‐specific cutoffs.ResultsPatients were predominately men (n = 457, 67%), and cirrhosis aetiology was hepatitis C virus in 269 patients (40%), alcohol in 153 (23%), non‐alcoholic steatohepatitis/cryptogenic in 96 (14%), autoimmune liver disease in 55 (8%), hepatitis B virus in 43 (6%), and others in 5 patients (1%). Sarcopenia was present in 292 (43%), 135 had sarcopenic obesity (20%) and 353 had myosteatosis (52%). Patients with sarcopenia (22 ± 3 vs. 95 ± 22 months, P < 0.001), sarcopenic obesity (22 ± 3 vs. 95 ± 22 months, P < 0.001), and myosteatosis (28 ± 5 vs. 95 ± 22 months, P < 0.001) had worse median survival than patients without muscular abnormalities. By multivariate Cox regression analysis, both sarcopenia [hazard ratio (HR) 2.00, 95% confidence interval (CI) 1.44–2.77, P < 0.001], and myosteatosis (HR 1.42, 95% CI 1.02–1.07, P = 0.04) were associated with mortality.ConclusionsSarcopenia, sarcopenic obesity and myosteatosis are often present in patients with cirrhosis, and sarcopenia and myosteatosis are independently associated with a higher long‐term mortality in cirrhosis.

OBJECTIVES:Limitations of the Model for End-Stage Liver Disease (MELD) score include its failure to assess the nutritional and functional status of cirrhotic patients. Our objectives were to evaluate the impact of sarcopenia in cirrhosis and whether the inclusion of muscularity assessment within MELD could improve the prediction of mortality in patients with cirrhosis.METHODS:We included 669 cirrhotic patients who were consecutively evaluated for liver transplantation. Skeletal muscle index at the third lumbar vertebra (L3 SMI) was measured by computed tomography, and sarcopenia was defined using previously published gender and body mass index–specific cutoffs. Using Cox proportional hazards regression, a novel MELD-sarcopenia score was derived.RESULTS:Sarcopenia was present in 298 patients (45%); sarcopenic patients had shorter median survival than non-sarcopenic patients (20±3 vs. 95±24 months, P<0.001). By Cox regression analysis adjusted for age, gender, and hepatocellular carcinoma, both MELD (hazard ratio (HR) 1.08, 95% confidence interval (CI) 1.06–1.10, P<0.001), and the L3 SMI (HR 0.97, 95% CI 0.96–0.99, P<0.001) were associated with mortality. Overall, the c-statistics for 3-month mortality were 0.82 (95% CI 0.78–0.87) for MELD and 0.85 (95% CI 0.81–0.88) for MELD-sarcopenia (P=0.1). Corresponding figures for 1-year mortality were 0.73 (95% CI 0.69–0.77) and 0.77 (95% CI 0.73–0.80), respectively (P=0.03). The c-statistics for 3-month mortality in patients with MELD<15 (0.85 vs. 0.69, P=0.02) and refractory ascites (0.74 vs. 0.71, P=0.01) were significantly higher for MELD-sarcopenia compared with MELD.CONCLUSIONS:Modification of MELD to include sarcopenia is associated with improved prediction of mortality in patients with cirrhosis, primarily in patients with low MELD scores. External validation of this prognostic index in larger cohorts of cirrhotic patients is warranted.

Muscle depletion or sarcopenia is associated with increased mortality in patients with cirrhosis; how it affects mortality after liver transplantation requires further study. In this study, we aimed to establish whether sarcopenia predicts increased morbidity or mortality after liver transplantation. We analyzed 248 patients with cirrhosis who had a computed tomography (CT) scan including the third lumbar vertebra before liver transplantation. Data were recovered from medical charts, the skeletal muscle cross-sectional area was measured with CT, and sarcopenia was defined with previously published sex-and body mass index-specific cutoffs. One hundred sixty-nine patients (68%) were male, and the mean age at transplantation was 55 6 1 years. The etiologies of cirrhosis were hepatitis C virus (51%), alcohol (19%), autoimmune liver diseases (15%), hepatitis B virus (8%), and other etiologies (7%). Sarcopenia was present in 112 patients (45%), and it was more frequent in males (P 5 0.002), patients with ascites (P 5 0.02), and patients with higher bilirubin levels (P 5 0.05), creatinine levels (P 5 0.02), international normalized ratios (P 5 0.04), Child-Pugh scores (P 5 0.002), and Model for End-Stage Liver Disease scores (P 5 0.002). The median survival period after liver transplantation was 117 6 17 months for sarcopenic patients and 146 6 20 months for nonsarcopenic patients (P 5 0.4). Sarcopenic patients had longer hospital stays (40 6 4 versus 25 6 3 days; P 5 0.005) and a higher frequency of bacterial infections within the first 90 days after liver transplantation (26% versus 15%, P 5 0.04) in comparison with nonsarcopenic patients. In conclusion, sarcopenia is one of the most common complications in patients with cirrhosis and is predictive of longer hospital stays and a higher risk of perioperative bacterial infections after liver transplantation, but it is not associated with increased mortality.

The ESAS-r retains core elements of the ESAS, with improved interpretation and clarity of symptom intensity assessment. It represents the next generation of ESAS development, with further validation recommended for drowsiness, appetite, and well-being.

Sarcopenia is present in almost one third of patients with HCC, and constitutes a strong and independent risk factor for mortality. Our results highlight the importance of body composition assessment in clinical practice.
