Protein-energy malnutrition is an inevitable consequence of chronic liver disease, particularly in the developing infant. Severe malnutrition with loss of fat stores and muscle wasting affects between 60% and 80% of infants with liver disease (Beath, 1993a; Holt et al, 1997). Reduced energy intake secondary to anorexia, vomiting and fat malabsorption, in association with a disordered metabolism of carbohydrate and protein, increased energy requirements and vitamin and mineral deficiencies, contributes towards growth failure. Reversal of malnutrition is one of the key aims of liver transplantation and is achieved in the majority of long-term survivors. The aetiology of persistent growth failure post-transplantation is multifactorial and is related to pre-operative malnutrition, glucocorticoid administration, feeding problems and post-operative complications. Strategies to prevent pre- and post-transplant growth failure include early referral for liver transplantation and a multidisciplinary approach to nutritional support, which may increase survival and improve the quality of life and outcome of liver transplantation.
蛋白质 - 能量营养不良是慢性肝病不可避免的后果,在发育中的婴儿中尤为如此。严重营养不良伴有脂肪储备减少和肌肉消瘦,影响60%至80%的肝病婴儿(比思,1993a;霍尔特等人,1997)。由于厌食、呕吐和脂肪吸收不良导致能量摄入减少,再加上碳水化合物和蛋白质代谢紊乱、能量需求增加以及维生素和矿物质缺乏,导致生长发育迟缓。营养不良的逆转是肝移植的关键目标之一,大多数长期存活者都能实现这一目标。移植后持续生长发育迟缓的病因是多因素的,与术前营养不良、糖皮质激素的使用、喂养问题和术后并发症有关。预防移植前后生长发育迟缓的策略包括尽早转诊进行肝移植以及采用多学科方法进行营养支持,这可能会提高生存率并改善肝移植的生活质量和预后。
