Active clinical trials for "Metabolic Diseases"

The objective of this study is to determine the percentage of children with genetic markers putting them at increased risk of developing type 1 diabetes, and to offer the opportunity for these children to be enrolled into a phase II b primary prevention trial.

The aim of the present study is to determine if there is a change in quality and quantity of sleep perceived by adults and children with GSD and their parents while starting a modified UCCS (Glycosade) to prevent nocturnal hypoglycemia. The investigators also aim to evaluate if there is a change in quality of life perceived by adults and children and their parents with Glycosade.

The investigators will retrospectively analyze and compare data of 2 groups of overweight and obese patients: subjects who followed a diet based on Resting Energy Expenditure (REE) measured by indirect calorimetry and subjects who followed a diet based on REE estimated by the Harris-Benedict equation. Propensity score adjustment will be used to adjust for known differences between the 2 groups

To study, prospectively, the association between dietary patterns and risk of health outcomes (cardiovascular, metabolic, endocrine, neurological, skeletal muscular, cancer) in cohort study of 116,671 women age 24 to 44 years at baseline in 1989 (the Nurses' Health Study II; NHS II).

Chronic hepatitis C infection is associated with changes of glucose metabolism end increased frequency of impaired glucose tolerance. This might be a additional risk factor for disease and fibrosis progression. The study aims to evaluate whether a therapy with direct-acting antiviral agents leading to a sustained virologic response directly impacts parameters reflecting glucose metabolism and fibrosis.

The purpose of this study is to collect a variety of clinical data and blood glucose changes using a continuous glucose monitoring device for high-risk diabetes patients (prediabetes) in order to develop a personalized diabetes prevention and management platform based on artificial intelligence model using mathematical analysis.

The study aims to test web-based strategies, in overweight or obese participants at risk or affected by Type 2 Diabetes Mellitus , to promote adherence over time to a healthy lifestyle and nutritional medical therapy (TMN). The study population includes 40 subjects, randomly allocated to web group (therapeutic reinforcement through web-based strategies) or traditional group (traditional educational approach). Anthropometric and clinical parameters will be collected, as well as scores of validated questionnaires will be administered up to 12 months from the enrollment.

Chronic alcoholic and metabolic liver diseases are the two main liver diseases in France. The long-term prognosis of these two diseases are not well known because main studies are retrospective and with only alcoholic patients. The knowledge of the natural history of these diseases should improve the management of patients with such diseases. The aim of this prospective cohort is to describe the natural history of patients with chronic liver disease due to alcohol or metabolic disease and to identify factors associated with complications of these liver diseases (cirrhosis, hepatocellular carcinoma, ascites. ..).

This study will provide medical evaluations for patients with known or suspected metabolic and genetic disorders. It will allow NICHD investigators and trainees experience in diagnosing, managing, and treating patients with metabolic and genetic disorders who may not be eligible for an active NIH research trial. Participants in this protocol will only have tests and procedures used in the standard practice of medicine; there will be no experimental tests or treatments. Patients who are found eligible for an active research protocol will be offered participation in that study. The medical evaluations in this trial may uncover new disease processes that prompt new research initiatives. People of all ages with a suspected or diagnosed genetic or metabolic condition may be eligible for this study. In addition, children with unexplained developmental delay, deafness, dysmorphism, congenital malformations, acidosis, failure to thrive, feeding problems, short stature, birth defects, and other syndromes of unknown cause may qualify. Participants will have a medical history, including a family history, with possible review of previous medical records, and a physical examination. Other procedures may include: Consultation with medical specialists. Hearing and/or vision tests. Imaging studies, such as X-rays, ultrasound and magnetic resonance imaging (MRI). Blood drawing Blood samples (2 to 4 tablespoons from adults and 1 to 2 tablespoons from children) may be used for routine lab tests, genetic study, and other research purposes. Cheek swab DNA may be obtained by a cheek swab. A small brush is rubbed against the inside of the cheek to collect some cells. Skin biopsy Under local anesthetic, a small circle of skin (about 1/8-inch) is removed with a sharp cutting instrument similar to a cookie cutter. Muscle biopsy Under local anesthetic, a small piece of muscle tissue is removed to aid in diagnosis. Participants will undergo only diagnostic procedures that are clinically indicated; that is, only tests needed to confirm or rule out a diagnosis will be done. Tissue samples collected for diagnostic purposes may also be used to obtain DNA for genetic studies and to establish cell lines (cells grown in the laboratory to be maintained indefinitely) for future research. The results of the medical evaluation may indicate whether or not the participant has the disease that runs in the family (if a genetic disorder is indeed confirmed). Unless he or she requests otherwise, the subject (and parent in the case of a minor) will receive counseling regarding the test results. The implications of a positive test result will be explained, specifically, the participant s risk of having the disease, and the risk of passing the condition on to offspring.

The purposes of this study are to identify gene mutations in patients with the muscle diseases phosphofructokinase (PFK) deficiency, acid maltase deficiency (GAA deficiency) and to learn more about how these diseases develop. PFK deficiency is a mild, exercise-related illness. The childhood form of GAA deficiency (Pompe disease) affects the heart and liver and is rapidly fatal. The adult form begins in midlife and involves degeneration of skeletal muscles, leading to weakness and muscle wasting. The following groups of individuals may be eligible for this study: Group A: Patients with PFK deficiency, acid maltase deficiency, and relatives who also are affected. Participants in this group will undergo a brief medical and family history, blood sample collection, and possibly a physical examination, review of medical records, and interview with the patient's physician. Group B: Unaffected family members of patients in group A, including both blood relatives and spouses. People in this group may be asked to provide a history and genetic information. A review of medical records, interview with the individual's physician, and blood sample may also be requested. Group C: Control subjects. This group will provide a small blood sample or buccal mucosal sample (tissue sample collected by brushing the inside of the cheek). The samples will be coded and the investigators will not know the participants' identities. DNA from these samples will be analyzed for frequency of gene mutations. Genetic counseling will be arranged for patients, as appropriate.
