While the increased rates of survival in childhood cancers have increased progressively in recent decades, many childhood cancer survivors will have at least one chronic health condition within 40 years of age. In this regard, cardiovascular complications have emerged as a leading cause of long-term morbidity and mortality in long-term survivors of childhood cancer, likely due to exposure to anthracycline chemotherapy, and outcomes in patients with anthracycline-related cardiomyopathy remain poor. Some progress has been made in understanding the mechanisms at the basis of anthracycline-related cardiomyopathy, which appear to involve generation of reactive oxygen species, leading to mitochondrial dysfunction, followed by myocyte apoptosis and maladaptive left ventricular remodeling...

Lipoprotein (a) [Lp(a)] is an independent risk factor for cardiovascular disease. There are currently limited therapeutic options to lower Lp(a) levels. L-Carnitine has been reported to reduce Lp(a) levels. The aim of this study was to compare the effect of L-carnitine/simvastatin co-administration with that of simvastatin monotherapy on Lp(a) levels in subjects with mixed hyperlipidemia and elevated Lp(a) concentration. Subjects with levels of low-density lipoprotein cholesterol (LDL-C) >160 mg/dL, triacylglycerol (TAG) >150 mg/dL and Lp(a) >20 mg/dL were included in this study...

BACKGROUND: Frailty is a biological syndrome of decreased reserve and resistance to stressors due to decline in multiple physiological systems. Amino acid deficiency, including L-carnitine, has been proposed to be associated with its pathophysiology. Nevertheless, the efficacy of L-carnitine supplementation on frailty status has not been documented. Thus, this study aimed to determine the effect of 10-week L-carnitine supplement (1.5 g/day) on frailty status and its biomarkers and also physical function, cognition, and nutritional status among prefrail older adults in Klang Valley, Malaysia...

The identification of impurities in l-carnitine by mass spectrometry is difficult because derivative reagents or ion pair reagents are usually used to separate and increase the retention of l-carnitine on the reversed-phase column. In this study, four impurities including 3-chloro-2-hydroxy-N,N,N-trimethylpropan-1-aminium, 3-cyano-2-hydroxy-N,N,N-trimethylpropan-1-aminium, 3-carboxy-N,N,N-trimethylprop-2-en-1-aminium and 4-chloro-2,3,4-trihydroxy-N,N,N-trimethylbutan-1-aminium were identified in l-carnitine and its tablets by using two-dimensional column-switching high-performance liquid chromatography coupled with linear ion trap mass spectrometry...

Ischemia is one of the most prominent risk factors of neurodegenerative diseases such as Alzheimer's disease. The effects of oxygen and glucose depletion in hippocampal tissue due to ischemia can be mimicked in vitro using the oxygen and glucose deprivation (OGD) model. In this study, we applied OGD on acute rat hippocampal slices in order to design an elementary yet quantitative histological technique that compares the neuroprotective effects of (l)-carnitine to known neuroprotectors, such as the N-methyl-d-aspartate (NMDA) receptor antagonist memantine and the gamma-aminobutyric acid (GABA)-B receptor agonist baclofen...

BACKGROUND: L-carnitine supplementation has been suggested to show several favorable effects on patients with liver cirrhosis (LC). However, there have been no reports regarding the effect of L-carnitine on energy metabolism in patients with LC using indirect calorimetry which is a well-established method for assessing the degree of liver malnutrition. We examined the effect of L-carnitine in patients with LC on energy metabolism using indirect calorimetry. METHODS: A total of 13 LC patients who are scheduled to be treated with L-carnitine (1,800 mg/day) were analyzed in this study...

The authors present a case of carnitine transporter deficiency, which was unmasked after an episode of respiratory distress resistant to treatment with bronchodilators. Chest radiograph showed cardiomegaly; electrocardiogram showed left ventricular hypertrophy and echocardiography revealed dilated cardiomyopathy. Heart failure therapy was initiated and metabolic screening was requested, as family history was indicative of inborn errors of metabolism. Very low levels of free carnitine and carnitine esters in blood were found and genetic testing confirmed the diagnosis of carnitine transporter deficiency...

BACKGROUND: The potential of fermented buckwheat as feed additives was studied to increase L-carnitine and gamma-aminobutyric acid (GABA) in designer eggs. Buckwheat contains high levels of lysine, methionine, and glutamate, which are precursors for the synthesis of L-carnitine and GABA. Rhizopus oligosporus was used for the fermentation of buckwheat to produce L-carnitine and GABA that exert positive effects like enhanced metabolism, antioxidant activities, immunity, and blood pressure control...

l-Carnitine, in addition to playing a fundamental role in the β-oxidation of fatty acids, has been recently identified as a modulator of immune function, although the mechanisms that underlie this role remain to be clarified. In this study, we addressed the modulation of l-carnitine transport and expression of related transporters during differentiation of human monocytes to macrophages. Whereas monocytes display a modest uptake of l-carnitine, GM-CSF-induced differentiation massively increased the saturable Na(+)-dependent uptake of l-carnitine...

This study performed untargeted metabolomics for plasma samples from 40 coronary heart disease patients and 43 healthy controls by high-performance liquid chromatography coupled with mass spectrometry technology to find a set of effective biomarkers for CHD diagnosis and prognosis. The discriminating metabolites were extracted and analyzed by univariate and multivariate analysis methods. We found five metabolites (1-naphthol, 2-naphthol, methylitaconate, N-acetyl-d-glucosamine 6-phosphate and l-carnitine) contributing to the separation of CHD patients from healthy controls, and a subset of two metabolites in these five were identified as potential plasma biomarkers for CHD diagnosis...
