Background: Carnitine is the essential cofactor for various enzyme activities of human metabolism, especially for the mitochondrial carnitine shuttle that transfers long-chain fatty acids as acylcarnitine esters across the inner mitochondrial membrane for Beta-oxidation and energy production. Intracellular carnitine deficiency induces an impairment of long-chain fatty acid oxidation. In human, approximately 75% of carnitine comes from the diet and 25% from endogenous liver synthesis. In the neonatal period, more specifically in the premature, liver synthesis capacity is reduced because of imma…

Insulin resistant subjects and type 2 diabetic patients are characterized by a decreased metabolic flexibility: a reduced capability to switch from fat oxidation in the basal state to carbohydrate oxidation in the insulin-stimulated state. This metabolic inflexibility is an early hallmark in the development of diabetes. Recent evidence suggests that a low carnitine availability may limit acetylcarnitine formation, thereby reducing metabolic flexibility. We propose to test the hypothesis that metabolic inflexibility in pre-diabetic subjects and diabetic patients is due to a reduced capacity to …

Sepsis is a severe and overwhelming response to an infection in the body. Over 750,000 patients in the United States develop sepsis every year. As sepsis becomes progressively more severe, a patient's blood pressure drops to dangerous levels and the body cannot pump oxygen to the rest of the body, which is necessary for normal cell function. This is called septic shock. When someone develops septic shock, it is very common for the smallest blood vessels in the body called the microcirculation to clog, like a highway during rush hour. Even with the best medical care, more than one in three pati…

Oxidative stress in renal cells may be a critical factor in the pathogenesis of pyelonephritis whereas pharmacological management of the oxidative stress response may provide a therapeutic effect in preventing renal pa…

There are some adults with skeletal muscle weakness (called "myopathy") and heart muscle weakness (called "cardiomyopathy") who have low blood levels of a compound called carnitine as a cause of their problems. Carnitine is very important to energy production in muscles. In fact, there are reports of some people with carnitine deficiency who have developed myopathy and cardiomyopathy that was completely reversed with carnitine treatment. The main objective of our project is to determine the number of patients who have carnitine deficiency as a cause of their myopathy and cardiomyopathy. The in…

Spinal muscular atrophy (SMA), an autosomal recessive disorder, is characterized by muscle weakness due to degeneration of anterior horn cells in the spinal cord and brain stem nuclei. It has a variable incidence of 1 in 6700 to 1 in 25000 live births and prevalence of 0.12 to 25 per 10,000 populations in different geographic areas and genetic constitution. A homozygous deletion/mutation involving exon 7 in SMN1 (survival motor neuron 1) is present in around 95% of the cases, resulting in the biochemical deficiency of the SMN protein. A genomic duplication at the same locus produces nearly ide…

The purpose of this study is to learn how treatment with acetyl-L-carnitine (ALCAR) will affect the hearts of patients with Friedreich's Ataxia as well as how it may affect other symptoms of Friedreich's Ataxia such as difficulties with balance, walking, or upper arm function.

The purpose of this study is determine whether combination Q10 , L-carnitine and multivitamin and mineral complex is effective in treatment of patients with low and intermidiate1-2 risk Myelodysplastic syndrome

Adding L-carnitine is more successful than clomiphene as a first line therapy for ovulation induction in women with clomiphene resistant PCOS

CIAKI is a common iatrogenic. Up to date the suggested treatments for CIAKI are partially effective and have not been approved by the Food and Drug Administration yet. The lack of effective nephroprotective drug for CIAKI, emphasizes the need not only for additional new drugs but also for new strategies that might also clarify CIAKI pathophysiology. To the best of our knowledge, the potentially beneficial effect of carnitine and PDE5 inhibitors on CIAKI prevention has not been examined, so far.

Diabetes mellitus (DM) is a growing disease and it is a public health concern, and projections of its future effect are alarming. About one third of those affected will develop diabetic nephropathy at 20 years after diagnosis. Of these patients, 20% will develop clinically end-stage renal disease ESRD, requiring renal replacement therapy (RRT). Patients with type 2 diabetes account for most patients with end stage renal disease (ESRD) and RRT. To the best of the investigators knowledge, the effects of MMF on diabetic nephropathy in patients with DM type II were not studied so far. Therefore, …

Attention-deficit hyperactivity disorder (ADHD) is the most common neurobehavioural disorder of childhood. The investigators hypothesized that carnitine would be beneficial for treatment of ADHD, and this could be evaluated in a double blind, randomized, parallel group comparison of carnitine+methylphenidate and methylphenidate +placebo. This will be a six-week, parallel group, randomized clinical trial undertaken in an outpatient child and adolescent clinic at Roozbeh Psychiatric Hospital in Tehran, Iran during April 2010-May 2010. 40 male and female subjects, ages 6 to 17 years with a Diag…

Many cases of male infertility are poorly understood and regarded as unexplained. Therefore, a etiological treatment for this condition can not be offered in most cases. A beneficial effect on sperm motility was found in trails using antioxidants such as carnitine, zinc and folic acid. However, most studies lacked a sufficient power to detect a significant effect on pregnancy rates. In this study, infertile men with abnormal sperm quality parameters will be randomized to receive either carnitine-based food supplement (Porimore) or folate and Zinc Tablets.

This is a study designed to test the hypothesis that treatment with L-carnitine will improve the quality of life and some specific symptoms and signs in patients with renal failure submitted to hemodialysis.

The purpose of this study is to determine whether Acetyl L-carnitine can prevent the development of nerve damage, known as neuropathy, in individuals taking anti-HIV drugs over a 48-week period. In addition the safety and tolerability of Acetyl L-carnitine will be assessed. This study compares the use of Acetyl L-carnitine or placebo (a dummy drug) in the prevention of nerve damage. The current standard of care is to use painkillers to manage the pain, with little or no effect. The possible beneficial effects of taking Acetyl L-carnitine is to prevent nerve damage as a result of anti-HIV medi…

The purpose of this study is to see if it is safe and effective to give adefovir (a new anti-HIV drug) plus nelfinavir to HIV-infected children who are already receiving other anti-HIV medications.
