Abstract
Glucose turnover rates were estimated with [2H2]glucose in five children with glycogen storage disease type I (GSD I) during sequential withdrawal of an infusion of glucose to determine whether their hypoglycemia was the result of decreased glucose production or increased rates of glucose utilization. Plasma glucose concentrations were 78 +/- 5 mg/dl during infusion of glucose at 6 mg X kg-1 X min-1 and decreased to 53 +/- 3 and 45 +/- 7 mg/dl during the 3 and 1.5 mg X kg-1 X min-1 glucose infusions, respectively. Total glucose flux during the 6 mg X kg-1 X min-1 glucose infusion was 7.3 +/- 0.7 mg X kg-1 X min-1 and decreased with reduction in the rate of glucose infused. Endogenous glucose production increased with each decrease in the rate of exogenous glucose infused. Following discontinuation of glucose infusion, endogenous glucose production was 3.9 +/- 0.3 mg X kg-1 X min-1, a value that was lower (P less than 0.05) than that observed in overnight-fasted normal children (6.3 +/- 0.3 mg X kg-1 X min-1) but not statistically different from the Ra of normal children fasted for 30 h (4.1 +/- 0.5 mg X kg-1 X min-1). Thus, children with GSD have glucose production rates that are 40% lower than those of normal children fasted overnight but equal to those of normal children fasted 30 h. Rates of glucose utilization during the 6 mg X kg-1 X min-1 glucose infusion were higher (0.05 less than P less than 0.1) than those of overnight-fasted normal children, despite lower plasma glucose concentrations when expressed on a body weight basis but not when expressed on the basis of estimated brain weight.
