[Glucose-1-phosphate associated with total parenteral feeding. Study of various metabolic effects and leukocyte...

The effects of glucose-1-phosphate (250-500 ml given by i.v. infusion over a period of 3-4 h for 3-5 days) on the quantity of exogenous insulin administered and on leukocyte adhesion and chemotaxis were studied in 4 groups of post-operative patients submitted to TPN (total parenteral nutrition), TPN + glucose-1-phosphate, standard infusion therapy and standard infusion therapy + glucose-1-phosphate respectively. With the use of glucose-1-phosphate the quantity of insulin administered could be significantly reduced (P less than 0.01) thereby an increased utilization of glucose, induced by the phosphorylated saccharide, was confirmed. Moreover, glucose-1-phosphate, through its action on intracellular sugar metabolism, increased leukocyte adhesion during TPN. This phenomenon might have a favourable effect on some of the functions carried out by these cells on the inflammatory response.
