|metadata.artigo.dc.description.abstract:||Background The 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. Methods The 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. Results Seventeen patients were included. REE was elevated at 30 days and reduced at the end of the study (P<0.05). Hypermetabolism/hypometabolism were low but present at the end of the study (11.8% of each). Increases in body weight and fat mass were observed (P<0.05). Handgrip strength and phase angle improved after LTx (P<0.05). Energy balance was positive at all times after LTx, and an increase in fat intake occurred (P<0.05). After multivariate analyses (P<0.05), the REE before transplantation and triceps skinfold thickness were positively associated and the cumulative dose of prednisone was negatively associated with REE after LTx. The presence of hypermetabolism was significantly associated with the presence of hypermetabolism before LTx and the cumulative dose of prednisone. Percentage of fat intake and fat mass before LTx was associated with hypometabolism. Conclusion Some potential modifiable factors are related to resting energy metabolism in patients undergoing LTx. Adequate and individualized nutritional guidance should be started before LTx.|
