[Ambulatory parenteral nutrition in short bowel syndrome: a retrospective study].

Parenteral nutrition via an indwelling central venous catheter was undertaken at home over a total period of 24,747 days in 34 patients with the short-bowel syndrome (of various causes). In some of the patients there developed complete adaptation of the residual intestine so that parenteral nutrition could be terminated. Complications were: infection, thrombosis, pulmonary embolism and metabolic problems. But the method proved to be suitable for improving the quality of life of these patients.

Parenteral nutrition with an amino acid solution containing a mixture of dipeptides. Evidence for efficient utilization of dipeptides in man.

Ten healthy human subjects received parenteral nutrition consisting of 80 g of a dipeptide-amino acid mixture and 900 carbohydrate calories infused over a period of 12 h, and then fasted for another period of 12 h. The dipeptides included in the mixture were: glycyl-L-glutamine, glycyl-L-tyrosine, glycyl-L-leucine, glycyl-L-isoleucine, and glycyl-L-valine. Parenteral nutrition with the dipeptide-amino acid mixture was without any adverse reaction in any of the subjects. The urinary excretion of the 5 dipeptides during parenteral nutrition ranged between 1 and 2% of the amount infused. Plasma concentrations of dipeptides during parenteral nutrition, which ranged from 8-96 microM reflected their plasma half-lives. Glycyl-L-glutamine had the longest half-life, glycyl-L-leucine and glycyl-L-tyrosine the shortest half-lives. During parenteral nutrition there were increases in plasma amino acid concentrations including those of glutamine and tyrosine. Discontinuation of parenteral nutrition resulted in the disappearance of dipeptides from plasma, and the dissipation of increased plasma amino acid concentrations. In conclusion, the present results show efficient utilization of glycyl-dipeptides as substrates for parenteral nutrition in man. The results further show that the structure of amino acids in the C-terminal position has a significant influence on the metabolism of dipeptides.

Decrease in plasma amino acid level after secretin and pancreozymin as an indicator of exocrine pancreatic function.

Total plasma amino acids were determined by the ninhydrin method in 37 controls and 30 patients with chronic pancreatitis and normal (n = 7) pancreatic enzyme output or mildly (n = 6), moderately (n = 8), and severely (n = 9) reduced pancreatic enzyme output. Intravenous injection of synthetic secretin did not change plasma amino acid levels. During a combined intravenous infusion of secretin (1 CU/kg X h) and pancreozymin (1 Ivy dog unit/kg X h), amino acid concentrations decreased maximally by 31% +/- 19% (mean +/- SD) in controls, but only by 6.3% +/- 4.7% in patients with exocrine pancreatic insufficiency (p less than 0.001 vs. controls). At a cutoff limit of less than or equal to 12% for the decrease in total amino acids, mild exocrine insufficiency (20%-40% of mean normal chymotrypsin output) was identified with a sensitivity of 67%, whereas moderately to severely impaired function was detected in every case (overall sensitivity 91%). Pancreatic function, as assessed by duodenal intubation and the tubeless amino acid test, was significantly correlated (e.g., rs = 0.73 for chymotrypsin output, p much less than 0.001). In 15 controls and 13 patients with mildly (n = 5) to severely impaired pancreatic function, individual amino acids were estimated. Plasma serine kinetics completely distinguished both groups. Kinetics of serine, valine, isoleucine, and histidine correlated even better with pancreatic function than those of total amino acids.
