Glycogen storage disease type I. Results of treatment with frequent daytime feeding, combined with nocturnal intragastric feeding and with administration of an alpha-glucosidase inhibitor.

Seven patients with glycogen disease type I have been treated with nocturnal intragastric feeding combined with frequent daytime feeding. Follow-up shows a striking improvement in their clinical condition including growth rate. Determination of biochemical parameters reveals a significant increase in mean blood glucose levels and a significant decrease of lactate, pyruvate, alanine, uric acid, triglycerides, and SGOT in blood. Additional administration of an alpha-glucosidase inhibitor in four patients caused a significant increase in blood lactate despite unchanged blood glucose levels.
