The utilization of glucose, fructose, and galactose was studied by oral tolerance tests in four patients with liver glycogen disease, two having a phosphorylase deficiency, the other two a glucose-6-phosphatase deficiency.
The utilization of these sugars was evaluated by the estimation of glucose, total reducing capacity, non-esterified fatty acids (NEFA), and lactate in the blood. The data were plotted against time and the curves obtained in the two types of abnormal carbohydrate metabolism and in two control children were compared.
The curves in children with phosphorylase deficiency approached the normal pattern.
In children with glucose-6-phosphatase deficiency, however, the curves for fructose and galactose were highly abnormal.
It was concluded that in the latter case fructose and galactose should be excluded from the diet.
