Infections ACLF Death Different clinical courses of acutely decompensated cirrhosis Pre-ACLF Unstable decompensated cirrhosis Stable decompensated cirrhosis 0 90 180 270 360 Days Highlights Patients with acutely decompensated cirrhosis without ACLF develop 3 different clinical courses. Patients with pre-ACLF develop ACLF within 90 days and have high systemic inflammation and mortality. Patients with unstable decompensated cirrhosis suffer from complications of severe portal hypertension. Patients with stable decompensated cirrhosis have less frequent complications and lower 1-year mortality risk.
This study offers an easy-to-apply MRI-based measurement of fat-free muscle mass as a marker of sarcopenia in decompensated patients; while TIPS might improve sarcopenia and thereby survival, persistence of sarcopenia after TIPS is associated with a reduced response to TIPS and a higher risk of acute-on-chronic liver failure development and mortality.

Liver and spleen SWE correlate with portal pressure and can both be used as a non-invasive method to investigate CSPH. Even though external validation is still missing, these algorithms to rule-out and rule-in CSPH using sequential SWE of liver and spleen might change the clinical practice.
Assessing the patients' risk for malnutrition by RFH-NPT may be a useful predictor of disease progression and outcome for patients with chronic liver disease.
Hepatic JAK2/ARHGEF1/ROCK expression is associated with portal hypertension and decompensation in human cirrhosis. The deletion of Jak2 in myofibroblasts attenuated experimental fibrosis and acute inhibition of JAK2 decreased PP. Thus, JAK2 inhibitors, already in clinical use for other indications, might be a new approach to treat cirrhosis with portal hypertension.
INTRODUCTION:
Muscle mass has been shown to be a prognostic marker in patients with liver cirrhosis. Transversal psoas muscle thickness normalized by height (TPMT/height) obtained by routine computed tomography is a simple surrogate parameter for sarcopenia. TPMT/height, however, is not sex specific, which might play a role in risk stratification. Its association with acute-on-chronic liver failure (ACLF) has not been established yet. ACLF is associated with systemic inflammatory dysregulation. This study aimed at evaluating the role of sarcopenia in ACLF development of patients with decompensated cirrhosis receiving transjugular intrahepatic portosystemic shunt (TIPS) using sex-specific TPMT/height.
METHODS:
One hundred eighty-six patients from the prospective Non-invasive Evaluation Program for TIPS and Follow Up Network cohort (observational, real-world TIPS cohort with structured follow-up) were analyzed. TPMT/height was measured from routine computed tomography. The sex-specific cutoff was determined to classify patients as sarcopenic and nonsarcopenic for 1-year mortality after TIPS. Clinical outcome was compared. Primary end points were ACLF and 1-year mortality after TIPS. Secondary end points were development of decompensations (hepatic encephalopathy and ascites) after TIPS.
RESULTS:
The sex-specific cutoff increases the diagnostic accuracy with regard to primary and secondary end points compared with the unisex cutoff. Sex-specific sarcopenia classification is an independent predictor of 1-year mortality and ACLF development in patients with cirrhosis receiving TIPS. Patients in the sarcopenia group showed significantly higher rates of mortality, ascites, overt hepatic encephalopathy, and ACLF after TIPS compared with the nonsarcopenia group. The Chronic Liver Failure Consortium Acute Decompensation score as a marker of systemic inflammation was significantly higher in sarcopenic patients.
CONCLUSIONS:
This study demonstrates for the first time that sarcopenia is related to ACLF development and systemic inflammation. The prognostic value of TPMT/height can be improved by using sex-specific cutoffs.
