Glucose-galactose malabsorption: demonstration of specific jejunal brush border membrane defect.

Glucose-galactose malabsorption: demonstration of specific jejunal brush border membrane defect.

Jejunal brush border glucose transport was studied in a patient with glucose-galactose malabsorption and in controls, using jejunal brush border membrane vesicles (BBMV) prepared from conventional jejunal biopsies. Whereas BBMV from controls showed a seven-fold enhancement of D-glucose uptake in the presence of an inwardly directed sodium gradient compared with its absence, no such enhancement ...

Congenital glucose galactose malabsorption.

Introduction Congenital glucose galactose malabsorption (CGGM) is a rare autosomal recessive disorder, which presents as a protracted diarrhoea in early neonatal life. It is due to a defect in sodium coupled transport of glucose and galac­ tose in the enterocyte (1). Diarrhoea in CGGM is osmotic, caused by accumulation of unabsorbed glucose and ga­ lactose in the intestine (2), which results in...

Genetic Disorders of Membrane Transport I. Glucose Galactose Malabsorption

Wright, Ernest M. Genetic Disorders of Membrane Transport. I. Glucose Galactose Malabsorption. Am. J. Physiol. 275 (Gastrointest. Liver Physiol. 38): G879–G882, 1998.—Glucose Galactose Malabsorption is a genetic disorder caused by a defect in glucose and galactose transport across the intestinal brush border. Normally, lactose in milk is broken down into glucose and galactose by lactase, an ect...

A Case Report of Glucose-Galactose Malabsorption in Iranian Child

Introduction Glucose-Galactose Malabsorption (GGM) is an autosomal recessive and rare disorder of intestinal transport of glucose and sodium-glucose cotransporter type (SGLT1). Case Report Our patient is a 32-day-old boy who was examined for severe diarrhea and acidosis and was treated with GGMdiagnosis. A number of laboratory tests were performed on this patient as well as positive test for r...
