“…An increase of the adminis- tration rate by this value amounts to a rise o f the plasma level by 9.0 mg/100 ml and an additional urinary fructose loss o f 7.56 mg/kg/h. The utilization is en hanced under these circumstances by 0.094 g/kg/h (26). These values are in good agreement with those by Strack et al (22) in the rabbit.…”

“…Compared to glucose (15) and fructose (6,14) it takes much longer to obtain a constant blood level when maltose is infused. The reasons remain to be determined.…”

Utilization of Intravenous Maltose

Ten healthy male subjects received an infusion of 10 % maltose solution at a rate of 0.5 g/kg body weight/h for 345 min. Blood maltose levels rose continuously for the first hours; after 285 min a constant level was maintained. Concomitantly increasing maltosuria occurred; the total renal maltose excretion averaged 30.4 % of the administered dose. In addition to maltose losses, considerable glucosuria (up to 16 % of total carbohydrate excretion) was found. The glucosuria occurred in spite of normal blood glucose levels. Serum insulin did not rise during maltose infusion. In the majority of cases, glucose is the carbohydrate of choice for parenteral nutrition (6, 10). Nevertheless, other sugars need to be studied. Maltose, a disaccharide consisting only of glucose, is currently attracting attention. There is evidence that intravenous maltose is metabolized in man (9, 12, 13); however, data on the degree of the utilization of maltose are lacking. We report blood level, urinary excretion and utilization of maltose in healthy subjects during maltose infusion. Blood glucose, serum insulin, and urinary glucose excretion were also studied.

Fructose turnover and utilization in dependence on age were examined in 55 pre-term and term newborns appropriate for gestational age during continuous intravenous infusion of fructose (0.25–1.0 g . kg^––¹ · h^––1). (1) The linear turnover range of fructose is exceeded during the first 3 days of life independently of gestational age with infusions of 1.0 g · kg^––1 · h^––1. This, however, is not the case in pre-term and term infants 10–12 days old. For the postnatal development of the fructose metabolism, the age of life is important, but not the gestational age. (2) During the first 3 days of life in pre-term and term infants, less than 10% of the fructose infused are eliminated. Thus, the fructose utilization is high even in the neonatal period, amounting to more than 90%. (3) The influence of fructose on the blood glucose concentration is not uniform and depends on fructose intake rate, gestational age, and age of life. Hypoglycemias were not observed.
