As detected by cross-sectional imaging, severe muscle depletion, which is termed sarcopenia, holds promise for prognostication in patients with cirrhosis. Our aims were to describe the prevalence and predictors of sarcopenia in patients with cirrhosis listed for liver transplantation (LT) and to determine its independent prognostic significance for the prediction of waiting-list mortality. Adults listed for LT who underwent abdominal computed tomography/magnetic resonance imaging within 6 weeks of activation were retrospectively identified. The exclusions were hepatocellular carcinoma, acute liver failure, prior LT, and listing for multivisceral transplantation or living related LT. Sixty percent of the 142 eligible patients were male, the median age was 53 years, and the median Model for End-Stage Liver Disease (MELD) score at listing was 15. Fortyone percent were sarcopenic; sarcopenia was more prevalent in males versus females (54% versus 21%, P < 0.001) and increased with the Child-Pugh class (10% for class A, 34% for class B, and 54% for class C, P ¼ 0.007). Male sex, the dry-weight body mass index (BMI), and Child-Pugh class C cirrhosis (but not the MELD score) were independent predictors of sarcopenia. Sarcopenia was an independent predictor of mortality (hazard ratio ¼ 2.36, 95% confidence interval ¼ 1.23-4.53) after adjustments for age and MELD scores. In conclusion, sarcopenia is associated with increased waiting-list mortality and is poorly predicted by subjective nutritional assessment tools such as BMI and subjective global assessment. If this is validated in larger studies, the objective assessment of sarcopenia holds promise for prognostication in this patient population. Liver Transpl 18:1209-1216, 2012. V C 2012 AASLD. See Editorial on Page 1136The adoption of the Model for End-Stage Liver Disease (MELD) score for the allocation of deceased donor hepatic grafts has resulted in reductions in waiting-list mortality and the time to liver transplantation (LT). 1,2 Despite these advantages, the MELD score has recognized limitations, 3,4 including inferior performance in predicting mortality in a subgroup of patients with lower MELD scores. [5][6][7] In order to optimize the utility of the MELD score for the prediction of waiting-list mortality in a broader range of patients and to identify those patients at the greatest risk of deterioration,

A significant proportion of patients with a very high risk of CSPH, and a population with a very low risk of VNT can be identified with simple, noninvasive tests, suggesting that these can be used to individualize medical care. (Hepatology 2016;64:2173-2184).

In a retrospective analysis of almost 2000 patients, we found 60% to have SPSS; prevalence increases with deterioration of liver function. SPSS increase risk for HE and with a chronic course. In patients with preserved liver function, SPSS increase risk for complications and death. ClinicalTrials.gov ID NCT02692430.

5mm 5 mm Highlights Total cross-sectional SPSS area (TSA) predicts survival in patients with advanced chronic liver disease. The cutoff for TSA that is associated with worse survival corresponds to a single shunt of >10 mm diameter. This study may impact on the clinical use of TSA/SPSS for risk stratification and decision-making in the management of patients with cirrhosis.

Patient's listed for liver transplant have significant functional limitations, with a weighted mean VO2 below the threshold level required for independent living. Although heterogeneity in study designs with respect to timing, CPET variables, and cut-off values precluded the determination of CPET mortality thresholds, the studies support CPET as an objective and independent predictor of pre- and post-transplant mortality.

SUMMARY BackgroundMalnutrition is a common and clinically significant problem in patients with cirrhosis. The impact of nutritional therapy remains unclear.

In this large cohort of liver transplant waitlisted patients, very low protein intake was prevalent and independently associated with malnutrition and mortality. Unlike many other prognostic factors, protein intake is potentially modifiable. Prospective studies are warranted to evaluate the effect of targeted protein repletion on clinically relevant outcomes such as muscle mass, muscle function, immune function, and mortality.
