Acute hypoglycemia in children is not an uncommon disease that can be encountered in the Emergency Department. Most cases of childhood hypoglycemia are caused by ketotic hypoglycemia due to missed meals. Often, hypoketotic hypoglycemia can also occur, which suggests hyperinsulinemia or a defect in fatty acid oxidation. Carnitine is essential for long chain fatty acids transfer into mitochondria...
Introduction Familial Mediterranean fever (FMF) is an autosomal recessive disease characterized by recurring self-limited fever, abdominal pain and chest pain caused by serositis. FMF mainly affects Middle-East populations with a high prevalence in Sephardic Jews, Turkish, Arabs and Armenians. Carnitine is an important molecule in cellular energy metabolism. Secondary carnitine deficiency can b...
Carnitine/organic cation transporter (OCTN) 2 (SLC22A5) plays a pivotal role in renal tubular reabsorption of carnitine, a vitamin-like compound, on apical membranes of proximal tubules, but its role in relation to therapeutic drugs remains to be clarified. The purpose of the present study was to elucidate the involvement of OCTN2 in renal disposition of a beta-lactam antibiotic, cephaloridine ...
Deficiency of 3-hydroxy-3-methylglutaryl-coenzyme A (CoA) lyase affects the metabolism of leucine as well as ketogenesis. This disorder is one of an increasing list of inborn errors of metabolism that presents clinically like Reye's Syndrome or nonketotic hypoglycemia. Four patients with proven 3-hydroxy-3-methylglutaryl-CoA lyase deficiency were shown to excrete a new diagnostically specific m...
Background. Carnitine deficiency may contribute to cardiovascular disease (CVD) in patients with hemodialysis (HD). Dyslipidemia plays a role in CVD and its prevalence is also high in HD patients. We examined here the effects of switching from oral administration (PO) to intravenous (IV) injection of L-carnitine on lipid metabolism in patients with HD. Methods. Nine HD patients who had received...

Dopamine transporter deficiency syndrome due to SLC6A3 mutations is the first inherited dopamine 'transportopathy' to be described, with a classical presentation of early infantile-onset progressive parkinsonism dystonia. In this study we have identified a new cohort of patients with dopamine transporter deficiency syndrome, including, most significantly, atypical presentation later in childhoo...
Elevated propionyl C3 carnitine is the most common abnormality seen in tandem mass spectrometry newborn screening profiles, with an incidence of 0.15% seen in our South Australian newborn screening programme. The most common cause for this result in our population is vitamin B12 deficiency but differential diagnoses include the inherited disorders of propionic and methylmalonic acid metabolism ...
The aim of this study was to examine whether organic cation/carnitine transporter 2 (OCTN2/SLC22A5) plays a role in the human blood-brain barrier (BBB) by evaluating its functional activity in human brain endothelial cells (hCMEC/D3), which are considered to be a model of the BBB. The uptake of [(3)H]L-carnitine by hCMEC/D3 cells was time-, extracellular sodium- and concentration-dependent, w...
