Core Tip

Core tip: The loss of skeletal muscle mass, termed sarcopenia, is common in the setting of cirrhosis and liver transplant. Before liver transplant, it has been associated with increased morbidity and mortality. The long term effect of sarcopenia upon morbidity and mortality after transplant has been less rigorously studied. Data linking sarcopenia to adverse outcomes such as diabetes in the non-transplant setting are of interest especially with the high prevalence of post transplant metabolic syndrome. Current research on sarcopenia is limited by heterogeneity in the method to measure muscle mass and varied definitions of sarcopenia.
