After successful liver transplantation (LTx), excessive weight gain is common among recipients. This rapid change in body morphology has been attributed to immunosuppressive regimens. The liver's role as a metabolic sensor and its autonomic innervation are pivotal in relaying humoral and neural information to the hypothalamus, where ingestive behavior is determined and has largely been ignored. We examined and assessed the contribution of drugs, energy intake, and energy expenditure on weight gain after LTx. Twenty-three patients were followed up at 3-mo intervals after LTx. Energy expenditure was measured by indirect calorimetry and dietary intake by diet diaries, and body composition was assessed with anthropometry and multifrequency bioelectrical impedance analysis. Cumulative drug doses were calculated, and associations between body composition and immunosuppressive regimens and energy expenditure were examined. Nine months after LTx, 20 of 23 (87%) recipients were overweight or obese, despite three-fourths of this cohort being on weight-reduction regimens. After LTx, a decrease in measured energy expenditure was observed (60.3 +/- 1.6 kJ/kg of body cell mass pre-LTx versus 53.7 +/- 2.2 kJ/kg of body cell mass after 9 mo; P < 0.05). Multiple stepwise regression analysis showed that, when adjusted for body weight, the strongest predictor of fat mass at 9 mo after LTx was resting energy expenditure. Weight gain after LTx is not predicted by immunosuppressive drug dosage. The strong association between weight gain and energy economy might be a consequence of the loss of hepatic metabolic integration and accelerated further by increased energy intake. Effective management of weight gain will not be achieved until the mechanisms involved in altered energy homeostasis are elucidated.
