Active clinical trials for "Metabolic Diseases"

The proposed randomized controlled trial will test the effect of a low-carbohydrate diet on hemoglobin A1c among individuals with elevated hemoglobin A1c that are within the range of prediabetes or diabetes. Results may provide evidence about the role of carbohydrate restriction in individuals with or at high risk of type 2 diabetes.

The growing prevalence of obesity and type 2 diabetes (T2D) is a major public health problem. Recent studies have clearly established that the gut microbiota plays a key role in the investigator's propensity to develop obesity and associated metabolic health disorders. The gut microbiota compositions plays a decisive role in glucose metabolism and the chronic inflammatory state associated with insulin resistance. Consuming prebiotic rich diet, including polyphenol and inulin rich food could help modulate favorably the gut microbiota which could lead to a reduction of endotoxemia and beneficial metabolic health effects.

The purpose of this study is to determine the safety, tolerability, action and effectiveness of repeated doses of Erythrocyte Encapsulated Thymidine Phosphorylase (EE-TP) for the treatment of patients with Mitochondrial Neurogastrointestinal Encephalomyopathy (MNGIE). MNGIE is a rare inherited disease that mainly affects the digestive and nervous system and is caused by a defect in the function of an enzyme called thymidine phosphorylase. This loss of function causes certain molecules (thymidine and deoxyuridine) to accumulate in cells which leads to toxic damage to these cells. The disease can be confirmed by detecting variations (mutations) in the thymidine phosphorylase gene (TYMP). Currently there are no specific treatments for patients with MNGIE, whose effectiveness has been shown through clinical trials. The potential treatment for MNGIE offered in this trial is an enzyme replacement therapy, i.e. replacing functional thymidine phosphorylase. This treatment uses the patients own red blood cells in which thymidine phosphorylase is encapsulated to produce EE-TP (the study drug). EE-TP is created using a machine named a Red Cell Loader (RCL) and is then administered back to the patient.

The purpose of the study is to investigate, in healthy middle age subjects, effects of whole grain rye on cognitive functions, mood, and cardiovasculair risk markers

Iron deficiency is considered the most common nutritional deficiency worldwide and affects children and women in both non-industrialized as well as industrialized countries. The main regulatory molecule of iron metabolism is hepcidin, a hormone produced in the liver that regulates intestinal iron absorption, placental transport, recycling of iron by macrophages and release from stores. The expression of hepcidin is regulated by many mediators, one of which is Matriptase-2 - a transmembrane protease. Complete loss of function leads to the rare disease iron-refractory iron deficiency anemia (IRIDA). Matriptase-2 is encoded by the gene TMPRSS6 and the single nucleotide polymorphism (SNP) rs855791 causes a non-synonymous substitution (V736A) that reduces the activity of the protease to inhibit hepcidin transcription. Genome wide association studies have identified the TMPRSS6 SNP rs855791 has a strong association with red blood cell and iron parameters in the general population. The objectives of the study is to measure oral iron absorption and systemic iron utilization into red blood cells (RBC) using oral isotopic labels in subjects homozygotes for common variants of the TMPRSS6 gene with the SNP rs855791 (A736V); AA vs. VV subjects. The aim is to conduct an iron absorption study in 80 Taiwanese women of reproductive age, non-pregnant, non-anemic, investigating the effect of the genetic variants of the SNP rs855791. The participants will be split in two groups of equal size; wild type AA vs. mutation VV. Iron absorption and systemic utilization will be assessed by two test meals containing stable isotopes of iron.The primary outcome of the trial is the oral iron absorption from a test meal as compared between the two genotypes AA vs. VV. Secondary outcomes are the comparison iron status markers between the two genotypes.

The aim of this study is to compare the effect of fixed and free combination of atorvastatin/perindopril/amlodipine on blood pressure and lipid levels.

Comparative study between conventional fasting versus overnight infusion of lipid or carbohydrate on free fatty acids and insulin in obese patients undergoing elective first time on-pump coronary artery bypass grafting.

The primary purpose of this project is to evaluate effects in healthy humans on glucose tolerance of cereal products with high amounts of fermentable dietary fibre. Secondary issues are to investigate effects of the test foods on subjective appetite variables, mood variables and gut microbiota composition. The test food products will be consumed in the evening and test variables will be determined the next morning. The study will apply a randomized crossover study design.

Investigators will test the health effects of eating a dairy-based protein-rich breakfast or isocaloric breakfast and performing regular physical exercise training for 12 weeks in young overweight women (2 x 2 factorial design). Measurements of body composition, physical fitness, metabolic health parameters, faeces and urine metabolites, and food diary will be collected.

This is a dietary intervention study in students and staff of Westlake University, which is designed to provide evidence in support of N-of-1 methods as an approach to advance personalized nutrition. The primary aim is using a series of N-of-1 trials to determine the impacts of a high fat, low carbohydrate diet (HF-LC) on glucose metabolism and gut microbiota in subjects versus a low fat, high carbohydrate diet (LF-HC) at both the individual and group level.
