title: [Glycogen storage disease by amylo 1,6-glucosidase deficiency (author's transl)].
abstract: A case of liver glycogen storage disease with amylo 1,6-glucosidase deficiency is reported. Enlarged liver was found at birth, and it is now accompanied by splenomegaly, low fasting blood glucose with ketonuria, elevation of transaminase values and glycogen accumulation with connective periportal tissue in liver histological study. In this glucogenosis results of functional tests on carbohidrate metabolism and glycogen enzymatic assay showed a direct relationship between functional and biochemical behaviour of liver cells. Amylo 1,6-glucosidase deficiency is accompanied by absence of glucogenolysis when glucagon is administrated after a long fast, and an increase of blood glucose when glucagon is administrated after food ingestion. Glycolisis tests show blood lactate elevation when some hexose or alanine are administrated; glyconeogenesis tests show blood glucose elevation when hexose, alanine or glycerol are administrated.
