Requirements for protein and amino acids: applications to parenteral nutrition

摘要: In several clinical conditions, such as cancer, injury, burning, and malabsorption, there is often significant loss of body protein, in some other diseases, notably hepatic cirrhosis uremia, are abnormalities protein metabolism. the treatment all these maintenance or restoration content correction metabolic become major therapeutic objectives. order to reverse pathological changes metabolism, an important strategy adjustment diet, a potent way ensuring this by parenteral nutrition. It therefore design nutritional for various conditions along lines that will take advantage our current knowledge metabolism requirements. This contribution symposium describe three areas significance objectives: (i) current concepts regulation ; (ii) requirements normal subjects amino acids, alterations requirements caused disease modifications nutrient intake may be required delivery route ; (iii) parameters measuring depletion repletion.
