Sodium Lactate Infusion in GLUT1DS Patients

2019-10-08 08:47:33 | BioPortfolio


This study investigates the effect of lactate infusion on epileptic discharges on EEG and seizure frequency in glucose transporter 1 deficiency syndrome (GLUT1DS) patients.


In glucose transporter 1 deficiency syndrome (GLUT1DS) cerebral glucose uptake from the systemic blood circulation is limited, because of deficient transport of glucose across the blood-brain barrier by the transporter protein (GLUT1). Classically patients present with developmental problems, movement disorders and severe epilepsy. There is no curative treatment for GLUT1DS, and anti-epileptic drugs usually have little to no effect. The ketogenic diet, providing ketones as an alternative energy substrate for the brain is an effective treatment option for the epilepsy and movement disorders in many GLUT1DS patients. Unfortunately, not in all GLUT1DS patients the ketogenic diet has a positive effect and other treatment options for these patients are very limited.

Traditionally, lactate is seen as a waste product of glycolysis during anaerobic conditions and a marker of ischemia. Interestingly, research has shown the beneficial side of lactate as an energy source for different organs. It seems that the brain can indeed use lactate as an alternative energy metabolite, besides glucose and ketones. The aim of this study is to investigate whether lactate can be an alternative energy metabolite in the GLUT1DS brain, and reduce epileptic discharges on EEG when intravenously administered in patients with GLUT1DS.

Medical and Biotech [MESH] Definitions

A syndrome of DYSPHAGIA with IRON-DEFICIENCY ANEMIA that is due to congenital anomalies in the ESOPHAGUS (such as cervical esophageal webs). It is known as Patterson-Kelly syndrome in the United Kingdom.

An autosomal recessive disorder of CHOLESTEROL metabolism. It is caused by a deficiency of 7-dehydrocholesterol reductase, the enzyme that converts 7-dehydrocholesterol to cholesterol, leading to an abnormally low plasma cholesterol. This syndrome is characterized by multiple CONGENITAL ABNORMALITIES, growth deficiency, and MENTAL RETARDATION.

A syndrome characterized by abdominal wall musculature deficiency, cryptorchism, and urinary tract abnormalities. The syndrome derives its name from its characteristic distended abdomen with wrinkled skin.

Rare, autosomal recessive disorder caused by deficiency of the beta 2 integrin receptors (RECEPTORS, LEUKOCYTE-ADHESION) comprising the CD11/CD18 family of glycoproteins. The syndrome is characterized by abnormal adhesion-dependent functions, especially defective tissue emigration of neutrophils, leading to recurrent infection.

A dietary deficiency of riboflavin causing a syndrome chiefly marked by cheilitis, angular stomatitis, glossitis associated with a purplish red or magenta-colored tongue that may show fissures, corneal vascularization, dyssebacia, and anemia. (Dorland, 27th ed)
