Resting Energy Expenditure, Body Composition, and Dietary Intake: A Longitudinal Study Before and After Liver Transplantation

BACKGROUNDThe loss of hepatic innervations after liver transplantation (LTx) might affect the energy metabolism of the patients. The aim of this study was to assess the resting energy expenditure (REE), body composition, and dietary intake before and during the first year after the LTx. METHODSThe REE was measured by indirect calorimetry. Nutritional status was assessed by anthropometric assessment, bioimpedance, handgrip strength, and dietary intake (before and 30, 90, 180, 270, and 370 days after LTx). Social, clinical, and nutritional variables were assessed as being potentially associated with REE or hypermetabolism and hypometabolism after LTx. RESULTSSeventeen patients were included. REE was elevated at 30 days and reduced at the end of the study (P
