Muscle Mass Via UltraSound in Cirrhosis (MMUSCLE)

In this study, the investigators will assess the prevalence and development of sarcopenia in the large in- and outpatient population with cirrhosis (n= 1346) of the University Hospital of Antwerp, using ultrasound assessment of muscle mass and quality in the lower as well as the upper limb muscles. Handgrip strength will be tested for muscle functional status. Findings will be correlated with clinical outcome (MELD, survival, decompensating events). The etiology of the cirrhosis and its underlying activity will be taken into account as dependent variables, e.g. whether there is a difference between compensated vs. decompensated cirrhosis. The investigators will screen for malnutrition using the RFH-NPT and compare with the GLIM criteria. The effect of sarcopenia on the quality of life will be evaluated using the validated "SarQoL®" (Sarcopenia Quality of Life) questionnaire.
