Nutrition in acute renal failure.
An important prognostic factor of acute renal failure (ARF) is the nutritional status of the patient. Malnutrition in ARF is mainly a consequence of profound catabolism, caused by alterations of the hormonal milieu, physical inactivity, infection, an enhanced proteolytic activity and the hemodialysis process. In the management of these patients, optimal nutritional intake must especially be discussed under the aspect of reducing catabolism. In catabolic ARF, an energy intake of about 50 kcal/kg/day provided by hypertonic glucose, may be adequate. The requirement of essential and nonessential amino acid solutions in respect of their composition and quantity is not clearly defined. High doses of amino acids failed to improve negative nitrogen balance in catabolic ARF. Recent approaches in order to reduce net protein breakdown imply new combinations of amino acid formulations or pharmacological trials for instance with antiproteolytic substances.
