Systemic primary carnitine deficiency (SPCD), also known as carnitine uptake defect, carnitine transporter deficiency (CTD) or systemic carnitine deficiency is an inborn error of fatty acid transport caused by a defect in the transporter responsible for moving carnitine across the plasma membrane. Carnitine is an important amino acid for fatty acid metabolism. When carnitine cannot be transported into tissues, fatty acid oxidation is impaired, leading to a variety of symptoms such as chronic muscle weakness, cardiomyopathy, hypoglycemia and liver dysfunction. The specific transporter involved with SPCD is OCTN2, coded for by the SLC22A5 gene located on chromosome 5. SPCD is inherited in an autosomal recessive manner, with mutated alleles coming from both parents. Acute episodes due to SPCD are often preceded by metabolic stress such as extended fasting, infections or vomiting. Cardiomyopathy can develop in the absence of an acute episode, and can result in death. SPCD leads to increased ...
TY - JOUR. T1 - Genetic deficiency of short-chain acyl-coenzyme A dehydrogenase in cultured fibroblasts from a patient with muscle carnitine deficiency and severe skeletal muscle weakness. AU - Coates, P. M.. AU - Hale, D. E.. AU - Finocchiaro, G.. AU - Tanaka, K.. AU - Winter, S. C.. PY - 1988/1/1. Y1 - 1988/1/1. N2 - Genetic deficiency of short-chain acyl-coenzyme A (CoA) dehydrogenase activity was demonstrated in cultured fibroblasts from a 2-yr-old female whose early postnatal life was complicated by poor feeding, emesis, and failure to thrive. She demonstrated progressive skeletal muscle weakness and developmental delay. Her plasma total carnitine level (35 nmol/ml) was low-normal, but was esterified to an abnormal degree (55% vs. controls of , 10%). Her skeletal muscle total carnitine level was low (7.6 nmol/mg protein vs. controls of 14 ± 2 nmol/mg protein) and was 75% esterified. Mild lipid deposition was noted in type I muscle fibers. Fibroblasts from this patient had 50% of control ...
The level and profiles of blood free carnitine and acylcarnitines, obtained by acylcarnitine analysis using tandem mass spectrometry, reflect various metabolic conditions. We aimed to examine the level of free carnitine and acylcarnitines in liver cirrhosis patients by acylcarnitine analysis and determine the clinical and subjective factors associated with blood carnitine fraction levels in liver cirrhosis. We compared blood carnitine fractions in 54 liver cirrhotic patients to other laboratory test results and questionnaire answers. In almost all patients, the blood levels of free carnitine (C0) and acetylcarnitine (C2) were within the normal reference range. However, in some patients, the levels of long-chain acylcarnitines, such as C16 and C18:1-acylcarnitine, were higher than the normal reference range. Liver function, assessed by Child-Pugh score, was significantly correlated with the blood level of each carnitine fraction measured (C0, C2, C3, C4, C6, C10, C12, C12:1, C14:1, C16, C18:1, and C18:2
A total of 59 gilts were used to determine the effects of supplemental L-carnitine on reproductive performance. Experimental treatments were arranged in a 2 × 3 factorial with main effects of L-carnitine (0 or 50 ppm) and day of gestation (40, 55, or 70). All gilts received a constant feed allowance of 3.86 lb/day and a top-dress containing either 0 or 88 mg of L-carnitine, starting on the first day of breeding and continuing until the day of harvest. Total litter size, total litter weight, and crown-to-rump length of fetuses were not different (P,0.10) between treatments at any gestation length. By d 70 of gestation, average fetus weight was heavier (P = 0.06) for fetuses from gilts fed L-carnitine, compared with fetuses from gilts fed the control diet. In addition, at d 70, fetal insulin-like growth factor- II (IGF-II) concentrations were lower (P = 0.09) for fetuses from gilts fed L-carnitine than for fetuses from gilts fed the control diet. Feeding L-carnitine may have decreased fetal ...
The introduction of Highly Active AntiRetroviral Therapy (HAART) for AIDS and HIV has improved survival considerably. However, HIV patients treated with HAART show significant metabolic symptoms, such as lipodystrophy, dyslipidemia, and insulin resistance. A possible contribution to these dysmetabolic symptoms in HIV/HAART is a decrease in mitochondrial function, resulting in a decreased fatty acid oxidation. Life style modulation such as aerobic exercise and L-carnitine supplementation may be beneficial to mitochondrial function. Aerobic exercise improves the biogenesis and function of mitochondria. A combined regime of aerobic and resistance training has been demonstrated to increase lean body mass and reduce overall fat and truncal fat and the levels of triglyceride and LDL cholesterol. L-Carnitine plays an important role in the transfer of long-chain acyl groups into the mitochondrial matrix and potentially improves energy metabolism. Further, L-carnitine supplementation decreases serum ...

TY - JOUR. T1 - Enhanced uptake of carnitine by perfused rat liver following starvation. AU - Kispal, Gyula. AU - Melegh, Bela. AU - Alkonyi, Istvan. AU - Sandor, Attila. PY - 1987/1/9. Y1 - 1987/1/9. N2 - Previously, the release of carnitine from the perfused rat liver was found to be protein-mediated, dependent on the nutritional state but not on metabolic energy. Further, it was shown to exceed the physiological demand by about 10-fold (Sandor et al. (1985) Biochim. Biophys. Acta 835, 83-91). In the present study the uptake of carnitine by perfused rat liver has been investigated. (1) The liver tissue and the perfusate were in equilibrium when the carnitine concentration in the perfusate was close to 45 μM, physiological in the rat plasma. Under this condition, when no net carnitine transport occurred, an unidirectional uptake of l-[3H]carnitine was observed. Quantitatively, the uptake rate was 355 ± 60 (S.D.) nmol/h per 100 g body weight at 45-50 μM perfusate concentration. This uptake ...
Vegetarian athletes generally eat better than their meat-eating counterparts, but there are some nutrients (e.g. vitamin B12) that they lack including one crucial amino acid that is key to muscle performance and recovery: carnitine.. Normally, carnitine is supplied in meat and dairy products, items that vegetarians usually avoid unless they are ovo-lacto (able to consume eggs and dairy) (1, 2). Blood concentrations of carnitine in vegetarians are reported to be strikingly low or around 20-30 percent lower than their meat-eating counterparts and suggests that tissue carnitine stores in the body are also low in concentration (3).. Unfortunately, lower carnitine intake in vegetarians has received relatively little attention (4). But the role carnitine plays in the body is one of heavy involvement in energy metabolism and cellular protection. Additionally, 95 percent of the bodys carnitine is found in muscle tissue.. Carnitine supplementation is shown to correct low concentrations and support ...
AL-DARAJI, H.J. and TAHIR, A.O.. Effect of L-carnitine supplementation on drake semen quality. S. Afr. j. anim. sci. [online]. 2014, vol.44, n.1, pp.18-25. ISSN 2221-4062.. This study was conducted to determine the effect on semen quality traits of supplementing the diets of Iraqi drakes with L-carnitine. Forty eight male Iraqi ducks, 30 weeks old, were randomly allocated to four treatments with 12 drakes per treatment group, replicated three times, with four drakes per replicate. The treatment groups consisted of birds fed a diet free of L-carnitine (T1, control group); birds fed a diet containing 50 mg L-carnitine/kg diet (T2); birds fed a diet containing 100 mg L-carnitine/kg diet (T3); and birds fed a diet containing 150 mg L-carnitine/kg diet. The drakes were fed the experimental diets only during the experimental period, which lasted three months. The semen quality traits that were investigated were ejaculate volume, mass and individual motility of spermatozoa, spermatocrit, spermatozoa ...
L-carnitine is concentrated in the epididymis, where sperm mature and acquire their motility (86). Two uncontrolled trials of L-carnitine supplementation in more than 100 men diagnosed with decreased sperm motility found that oral L-carnitine supplementation (3 grams/day) for three to four months significantly improved sperm motility (87, 88). However, no information on subsequent fertility was reported. A cross-sectional study of 101 fertile and infertile men found that L-carnitine concentrations in semen were positively correlated with the number of sperm, the percentage of motile sperm, and the percentage of normal appearing sperm in the sample (89), suggesting that L-carnitine levels in semen may be useful in evaluating male infertility. More recently, a placebo-controlled,double-blind, cross-over trial in 86 patients with male infertility found that L-carnitine (2 grams/day) supplementation for two months led to significantly improvements in sperm quality, evidenced by increases in sperm ...
Without carnitine, fats cannot be burned for energy. This explains the fascination with carnitine supplementation as a fat burner. In two separate studies, supplementation of carnitine (3 grams per day) for 10 days resulted in significantly higher rates of fat oxidation (1,2). This work was recently validated by researchers in the United Kingdom (3). They studied healthy endurance-trained men who supplemented with 80 grams of carbohydrate 2 times per day for 24 weeks. One group also received 2 grams l-carnitine l-tartrate (LCLT) in their carbohydrate beverage. Resting muscle carnitine was unchanged after 12 weeks but increased by 21% after 24 weeks in the carnitine group. When the carnitine group exercised at a low intensity after 24 weeks of supplementation, they showed the higher muscle carnitine was linked to significant muscle glycogen sparing (55% less) compared to controls. Work output was 35% greater than controls. Several lines of evidence support a role of carnitine in other processes ...
The acylcarnitines in plasma and blood spots of 23 patients with proven deficiency of long-chain 3-hydroxyacylcoenzyme A dehydrogenase were reviewed. Long-chain 3-hydroxyacylcarnitines of C14:1, C14, C16 and C18:1 chain length, and long-chain acylcarnitines of C12, C14:1, C14, C16, C18:2 and C18:1 chain length were elevated. Acetylcarnitine was decreased. In plasma, elevation of hydroxy-C18:1 acylcarnitine over the 95th centile of controls, in combination with an elevation of two of the three acylcarnitines C14, C14:1 and hydroxy-C16, identified over 85% of patients with high specificity (less than 0.1% false positive rate). High endogenous levels of long-chain acylcarnitines in normal erythrocytes reduced the diagnostic specificity in blood spots compared with plasma samples. The results were also diagnostic in asymptomatic patients, and were not influenced by genotype. Treatment with diet low in fat and high in medium-chain triglyceride decreased all disease-specific acylcarnitines, often to normal,
Raising your carnitine levels will fight this visceral fat gain because it increases fat burning, which has the effect of taking triglycerides and low-density lipoproteins out of the system so that they dont build up causing high cholesterol and atherosclerosis. A new research study in the journal Food and Chemical Toxicology illustrates this. Researchers gave a carnitine supplement to mice who were fed a high-fat diet in order to make them gain weight. In comparison to a group of mice fed a placebo, the carnitine group gained substantially less visceral and subcutaneous fat (fat that is right below the surface of the skin that you can pinch with your fingers). The placebo group exhibited the beginning stages of non-alcoholic fatty liver disease and atherosclerosis, neither of which were evident in the carnitine group ...

Our previous studies have identified a progressive development of endothelial dysfunction in shunt lambs that is dependent, at least in part, on decreased nitric oxide (NO) signaling. The purpose of this study was to evaluate the possible role of a disruption in carnitine metabolism in shunt lambs and to determine the effect on NO signaling. Our data ...
L-Carnitine L Carnitine deficiency has been identified in some dogs with dilated cardiomyopathy. Unfortunately we know from animal models that carnitine deficiency can be created by making the heart beat at very rapid heart rate (using a pacemaker); we also know that very rapid heart rates are common in dogs with DCM. Therefore the carnitine deficiency that was reported in earlier years may be the result of, rather than the cause of, DCM. So while we had all hoped that carnitine supplementation would resolve or prevent DCN in dogs, unfortunately it hasn’t. Many people choose to supplement L-carnitine in the diets of dogs with DCM and it is not likely to cause them any harm, but it is costly and may not be of any real benefit. Boxers with DCM should get 2-3 grams every 12 hours. If you want to supplement a Cocker Spaniel with DCM, the recommended dose is 1 gram of L-carnitine every 12 hours. DO NOT GIVE D-CARNITINE OF D,L-CARNITINE.. Taurine In the late 1980s taurine deficiency was ...
The conversion of 6-N-[Me-14C]trimethyl-lysine into carnitine and 4-N-trimethylaminobutyrate (butyrobetaine) was demonstrated in rats kept on a lysine-deficient diet. After the rats were given [14C]trimethyl-lysine for 4 days, a total of 17% of the injected label was recovered as carnitine from carcass and urine extracts. Another 8% of the trimethyl-lysine label was converted into 4-N-trimethylaminobutyrate, most of which was recovered from the urine. The conversion of trimethyl-lysine into the above two metabolites supports the pathway of carnitine biosynthesis as lysine+methionine → 6-N-trimethyl-lysine → 4-N-trimethylaminobutyrate → carnitine. In addition, three other metabolites representing 2% of the injected dose were recovered. Only an insignificant portion of the label was recovered as free trimethyl-lysine from the carcass, whereas 22% of the injected label was recovered in the urine. A relatively low specific radioactivity in carnitine was found when ...

This case study suggest that CoQ deficiency and the concomitant significant reductions in complex I, I+III, and II+III enzymatic activities in respiratory chain (RC) were responsable for the mitochondrial disorders observed in this patient. The observed muscle carnitine deficiency is most likely related to an increased reduced nicotinamide adenine dinucleotide-nicotinamide adenine dinucleotide ratio associated with respiratory chain defects. The increased ratio could impair beta-oxidation at the level of 3-hydroxyacyl- coenzyme A dehydrogenases, with a subsequent accumulation of acyl-coenzyme A beta-oxidation intermediates. These intermediates, released as carnitine esters, are transported into plasma and eliminated in urine, leading to secondary carnitine deficiency ...
New research by the Cleveland Clinic has found another reason why consuming a lot of red meat increases your risk of heart disease. Researchers are now convinced that the association between red meat and arteriosclerosis is more complex than just consuming bad fat. A chemical compound in red meat called carnitine, and the type of gut bacterial flora that you have also play an important role.. Large amounts of diet sourced carnitine are found in red meats and pork. For most people, dietary carnitine isnt necessary since your liver and kidneys also produce carnitine from the amino acids lysine and methionine.. How Does Dietary Carnitine Increase Your Risk Of Heart Disease?. The cardio health problems associated with dietary carnitine comes when certain bacteria in your intestines convert it into a chemical called trimethylamine-N-oxide or TMAO. TMAO is known to increase your risk of developing arteriosclerosis or clogged arteries that can lead to heart attacks and death.. By eating large amounts ...
Carnitine is a natural substance that the body uses to process fats and produce energy. Carnitine deficiency is when not enough of the nutrient carnitine is available to cells in the body. This can cause muscle weakness and heart or liver problems.
We determined the effects of supplemental L-carnitine on the insulin-like growth factor (IGF) system in porcine embryonic myoblasts (PEM) from gilts. Forty gilts (BW = 303.6 lb) were allotted to 1 of 4 treatments that were arranged in a 2 × 2 factorial, with main effects of L-carnitine (0 or 50 ppm) and day of gestation (55 or 70). All gilts were fed 3.86 lb/day and a top-dress containing either 0 or 50 ppm of L-carnitine, starting on the first day of breeding and continuing through the allotted gestation length. At d 55 or 70 of gestation, fetuses were removed for isolation of PEM from the hind-limb muscles. Real-time quantitative PCR was used to determine growth factor messenger RNA (mRNA) expression in cultured PEM at 72-, 96-, 120-, and 144-h after plating. Flow cytometry was used to analyze percentage of myogenic cells with a myoblast/myotube specific monoclonal antibody 5.1H11, and for determination of cell cycle stage. There was no treatment differences (P,0.10) for the expression of ...

April 11, 2013 A study published in Nature Medicine claims that carnitine, a compound abundant in red meat, sold as a dietary supplement, and present in some energy drinks, may increase the risk of heart disease. Carnitine typically helps the body transport fatty acids into cells to be used as energy. But researchers at the Cleveland Clinic found that in both humans and mice, certain bacteria in the digestive tract convert carnitine to another metabolite, called TMAO, which promotes atherosclerosis, or a thickening of the arteries. The researchers tested the carnitine and TMAO levels of omnivores, vegans, and vegetarians, and examined records of 2,595 patients undergoing cardiac evaluations. In patients with high TMAO levels, the more carnitine in their blood, the more likely they were to develop cardiovascular disease, heart attacks, stroke, and death. The researchers speculated that carnitine could be compounding the danger. "Cholesterol is still needed to clog the arteries, but TMAO changes ...

Intestinal microbiota metabolism of choline and phosphatidylcholine produces trimethylamine (TMA), which is further metabolized to a proatherogenic species, trimethylamine-N-oxide (TMAO). We demonstrate here that metabolism by intestinal microbiota of dietary L-carnitine, a trimethylamine abundant in red meat, also produces TMAO and accelerates atherosclerosis in mice. Omnivorous human subjects produced more TMAO than did vegans or vegetarians following ingestion of L-carnitine through a microbiota-dependent mechanism. The presence of specific bacterial taxa in human feces was associated with both plasma TMAO concentration and dietary status. Plasma L-carnitine levels in subjects undergoing cardiac evaluation (n = 2,595) predicted increased risks for both prevalent cardiovascular disease (CVD) and incident major adverse cardiac events (myocardial infarction, stroke or death), but only among subjects with concurrently high TMAO levels. Chronic dietary L-carnitine supplementation in mice altered ...

Abstract: A factorial bioassay was made to evaluate 4 different levels of exogenous saponin (S); 0 mg (So), 25 mg (S1), 50 mg (S2) and 75 mg (S3) per kg and also a combination (SC) of 50 mg saponin plus 50 mg L-carnitine (S4) per kg maize-soybean meal based basal diet during the late autumn. In all, 5 experimental diets being iso-nutritive (as per NRC, 1994 recommendation) but for variable in presence and contents of saponin and L-carnitine were prepared. 8-day old male broiler chicks (n=150, Starboro) were distributed randomly into 15 groups of 10 chicks in each housed in separate pen of littered floor. Three such groups received each of 5 test diets ad libitum as mash up to 8 weeks of age. The plenty of water was made available to all chicks during the experimental period. It was found that S2 diet significantly improved body weight gain (BWG) during growing (8 days to 3 weeks) period when compared with S0, S1, S3 and S4. Dietary S and SC had no significant (p>0.05) effect separately and ...

Effective evaluation or prediction of therapy response could be helpful for treatment of chronic kidney disease (CKD), which may rely on accurate biomarkers. Acylcarnitines are involved with lipid metabolism and mitochondrial function. The relation of acylcarnitines with treatment response in patients with CKD is unknown. The purpose of this study is to investigate the association of plasma acylcarnitines with renal function and its alteration by intervention in patients with IgA nephropathy (IgAN). A retrospective study was performed in 81 IgAN patients with treatment by traditional Chinese medicine (TCM). Multivariate linear regression analyses were performed to identify the association of acylcarnitines with baseline estimated glomerular filtration rate (eGFR) and eGFR changes after treatment. Twenty-seven acylcarnitines were measured at baseline and after 1-year TCM intervention. Certain short-chain and median-chain acylcarnitines were independently associated with baseline eGFR and eGFR alterations

The researchers examined the records of 2,595 meat eaters and vegetarians undergoing cardiac evaluations and found that patients with high levels of TMAO were more likely to develop cardiovascular disease and suffer heart attacks, strokes and death.. Dr. Stanley Hazen, chief of cellular and molecular medicine at Lerner, said carnitine may be compounding the negative effects of the cholesterol and saturated fat found in beef, pork and other red meat.. However, Dr. Betsy Booren, chief scientist at the American Meat Institute, noted that cardiovascular disease is "a complex condition" thats associated with a number of factors, from genetics to lifestyle, and attempts to link it to "a single compound found at safe levels in red meat oversimplifies" the issue.. Many other studies examining carnitine have not shown adverse effects at a number of doses, she said, adding that a fact sheet from the National Institutes of Health concludes that carnitine is essential and safe.. In fact, Hazen said some ...

L-Carnitine is known to improve blood sugar levels and sperm production, lower cholesterol, counteract symptoms of hyperthyroidism and fight heart disease. Since L-carnitine demonstrates antioxidant activity, it is sometimes used as a complementary therapy in treating various conditions related to oxidative stress, most notably heart disease and angina. In fact, The American Journal of Cardiology reports that this nutrient permits angina patients to exercise more with less pain and also to reduce medication levels. A few studies indicate that carnitine may also permit heart failure patients to experience similar results.. L-carnitine (the CAS No. is 541-15-1) also plays a role in preserving bone density. Unfortunately, this nutrient becomes less concentrated in bone along with osteocalcin, a protein secreted by osteoblasts that is involved in bone mineralization. In fact, these deficiencies are the main factors that contribute to osteoporosis in postmenopausal women. Studies have shown that this ...

BACKGROUND.l-Carnitine, an abundant nutrient in red meat, accelerates atherosclerosis in mice via gut microbiota-dependent formation of trimethylamine (TMA) and trimethylamine N-oxide (TMAO) via a multistep pathway involving an atherogenic intermediate, γ-butyrobetaine (γBB). The contribution of γBB in gut microbiota-dependent l-carnitine metabolism in humans is unknown. METHODS. Omnivores and vegans/vegetarians ingested deuterium-labeled l-carnitine (d3-l-carnitine) or γBB (d9-γBB), and both plasma metabolites and fecal polymicrobial transformations were examined at baseline, following oral antibiotics, or following chronic (≥2 months) l-carnitine supplementation. Human fecal commensals capable of performing each step of the l-carnitine→γBB→TMA transformation were identified. RESULTS. Studies with oral d3-l-carnitine or d9-γBB before versus after antibiotic exposure revealed gut microbiota contribution to the initial 2 steps in a metaorganismal l-carnitine→γBB→TMA→TMAO ...
Background:While mitochondria play an important role in innate immunity, the relationship between mitochondrial dysfunction and inflammation in heart failure (HF) is poorly understood. In this study we aimed to investigate the mechanistic link between mitochondrial dysfunction and inflammatory activation in peripheral blood mononuclear cells (PBMCs), and the potential anti-inflammatory effect of boosting NAD level.Methods:We compared the PBMC mitochondrial respiration of 19 hospitalized Stage D HF patients with 19 healthy participants. We then created an in vitro model of sterile inflammation by treating healthy PBMC with MitoDAMP (Mitochondrial Damage-Associated Molecular Patterns) isolated from human heart tissue. Lastly, we enrolled Stage D HF patients and sampled their blood before and after taking 5-9 days of oral nicotinamide riboside, an NAD precursor.Results:We demonstrated that HF is associated with both reduced respiratory capacity and elevated proinflammatory cytokine gene ...
BACKGROUND.l-Carnitine, an abundant nutrient in red meat, accelerates atherosclerosis in mice via gut microbiota-dependent formation of trimethylamine (TMA) and trimethylamine N-oxide (TMAO) via a multistep pathway involving an atherogenic intermediate, γ-butyrobetaine (γBB). The contribution of γBB in gut microbiota-dependent l-carnitine metabolism in humans is unknown. METHODS. Omnivores and vegans/vegetarians ingested deuterium-labeled l-carnitine (d3-l-carnitine) or γBB (d9-γBB), and both plasma metabolites and fecal polymicrobial transformations were examined at baseline, following oral antibiotics, or following chronic (≥2 months) l-carnitine supplementation. Human fecal commensals capable of performing each step of the l-carnitine→γBB→TMA transformation were identified. RESULTS.
