NCT ID: NCT03642405 Active, not recruiting - Depression Clinical Trials

Drug-induced Repolarization ECG Changes

Start date: August 15, 2018
Phase:
Study type: Observational

Studies have shown that the risk of developing heart arrhythmias, is increased in patients receiving medication for Attention-deficit hyperactivity disorder (ADHD) and depression. The QT-interval on a electrocardiogram (ECG) is often used to assess the patients risk of developing heart arrhythmias. The QT-interval defines the hearts electrical resting period and a long interval is linked to an increased risk of developing heart arrhythmias. In this project the investigators wish to examine possible side-effects in patients receiving medication for ADHD and depression and their dynamic QT-interval changes, by analysing the ECG changes that occur during "Brisk Standing".

NCT ID: NCT03548779 Active, not recruiting - Clinical trials for Autism Spectrum Disorder

North Carolina Genomic Evaluation by Next-generation Exome Sequencing, 2

NCGENES2
Start date: September 28, 2018
Phase: N/A
Study type: Interventional

The "North Carolina Clinical Genomic Evaluation by Next-gen Exome Sequencing, 2 (NCGENES 2)" study is part of a larger consortium project investigating the clinical utility, or net benefit of an intervention on patient and family well-being as well as diagnostic efficacy, management planning, and medical outcomes. A clinical trial will be implemented to compare (1) first-line exome sequencing to usual care and (2) participant pre-visit preparation to no pre-visit preparation. The study will use a randomized controlled design, with 2x2 factorial design, coupled with patient-reported outcomes and comprehensive clinical data collection addressing key outcomes, to determine the net impact of diagnostic results and secondary findings.

NCT ID: NCT03211039 Active, not recruiting - Genetic Diseases Clinical Trials

Perinatal Precision Medicine

NSIGHT2
Start date: June 29, 2017
Phase: N/A
Study type: Interventional

This study will seek to determine if rapid genomic sequencing improves outcomes for acutely ill infants. The investigator will enroll up to 1,000 acutely ill infants in a prospective, randomized, blinded study to either rapid Whole Genome Sequencing (WGS) or rapid Whole Exome Sequencing (WES, which is 2% of the genome and ~4-fold less expensive). 213 infants were actually enrolled. Outcomes will be measured both by objective clinical measures and family perceptions (patient/family centered outcomes). Primary analysis of WGS or WES will be in infants alone. Secondary analysis, in infants who do not receive a diagnosis, will be of families - ideally trios (mother, father, and affected infant), which is ~2-fold more expensive. Trios will be analyzed within the same randomization arm (WGS or WES). This study is designed to quantify which acutely ill infants benefit from rapid genomic sequencing, by how much they benefit, how they benefit, which rapid genomic sequencing method is superior, and the cost effectiveness of such testing.

NCT ID: NCT02921321 Active, not recruiting - Clinical trials for Musculoskeletal Diseases

Pilot Study of Cardiac MR in Patients With Muscular Dystrophy

Start date: January 2014
Phase:
Study type: Observational

Muscular Dystrophy can affect the skeletal muscles and also the heart and breathing muscles, causing significant morbidity and mortality. As patients are now living longer, treatment of muscular dystrophies involves drugs that help improve heart function. However, better types of heart imaging studies are needed to understand how these treatments work. Researchers want to improve heart imaging to identify earlier indicators of heart dysfunction in muscular dystrophy patients and how these are changed by medical treatment. The new imaging indicators will also help identify candidates for entry into future clinical trials.

NCT ID: NCT01851447 Active, not recruiting - Genetic Disorder Clinical Trials

Skeletal Muscle Biomarkers in People With Fragile Sarcolemmal Muscular Dystrophy

Start date: November 3, 2014
Phase:
Study type: Observational

Background: - Some kinds of muscular dystrophy affect the skeletal muscle membrane. In these conditions, the muscle membrane is more fragile. This affects how the muscles contract and relax, which causes movement problems. Researchers are looking at several muscle enzymes, or chemicals that affect how muscle cells function. By studying changes in these enzymes, they may be able to better understand how muscular dystrophy affects the cells. Researchers want to collect biomarkers (chemicals from blood samples) from people with fragile sarcolemmal muscular dystrophy. This information may provide better treatments for this condition. Objectives: - To study biomarkers that may affect the muscles of people with fragile sarcolemmal muscular dystrophy. Eligibility: - Individuals at least 18 years of age with fragile sarcolemmal muscular dystrophy. Design: - Participants will be screened with a medical history and physical exam. - Participants will be asked to come for four visits to the National Institutes of Health Clinical Center. The visits will be at least 2 months apart. Each visit will require participants to stay for 5 days at the clinical center. - During each visit, participants will provide frequent small blood samples. These samples will be collected while at rest and after physical exercise. - Participants will also have a physical therapy assessment. They will perform standard motor function tests and imaging tests (MRI, MRS). These tests may take up to 1 hour each time. - Treatment will not be provided as part of this study.

NCT ID: NCT01278277 Active, not recruiting - Genetic Disease Clinical Trials

Saffron Supplementation in Stargardt's Disease

STARSAF02
Start date: February 2011
Phase: Phase 1/Phase 2
Study type: Interventional

The general area of research in which this project has been designed is that of retinal degeneration related to mutations in the ABCR gene, responsible of Stargardt disease/fundus flavimaculatus retinal dystrophy (STD/FF). STG/FF is one of the major causes of vision impairment in the young age. STG/FF originates typically from the dysfunction and loss of cone and rod photoreceptors, developing through a photo-oxidative mechanism. The major disease locus is the central retina, i.e. the macula, whose neurons have the highest density and underlie critical functions such as visual acuity, color vision and contrast sensitivity. There is currently no cure for STG/FF. Recent experimental findings indicate that Saffron, derived from the pistils of Crocus Sativus, may have a role as a retinal neuro-protectant against oxidative damage. The stigmata of Crocus sativus contain biologically high concentrations of chemical compounds including crocin, crocetin, whose multiple C=C bonds provide the antioxidant potential. In addition it is well known that this compound is safe and free of adverse side effects. The aim of this research is to investigate the influence of short-term Saffron supplementation on retinal function in STG/FF patients carrying ABCR mutations. The macular cone-mediated electroretinogram (ERG) in response to high-frequency flicker (focal flicker ERG) will be employed as the main outcome variable. Secondary outcome variable will be the psychophysical cone system recovery after bleaching.

NCT ID: NCT00852943 Active, not recruiting - Immune Deficiency Clinical Trials

Screening Protocol for Genetic Diseases of Allergic Inflammation

Start date: November 2, 2010
Phase:
Study type: Observational

Background: - Mast cells are responsible for most symptoms of allergic reactions. In some allergic diseases, it is unusually easy to cause mast cells to release their contents and cause allergic reactions. In other cases, mast cells grow abnormally and, in rare cases, can result in tumors. Mast cells also control other parts of the immune system. - Understanding why mast cells behave abnormally in allergic diseases is important to finding better ways for diagnosing and treating these potentially life-threatening disorders. Objectives: - To screen mast cells at the genetic and functional levels to characterize abnormalities, identify mutations, detect carrier states, and/or develop therapies for such disorders. - To create a library of information about inherited diseases of mast cell homeostasis and activation, including piebaldism (problems with skin and hair pigmentation), anaphylaxis (severe allergic reaction), allergies, asthma, atopic dermatitis (eczema), allergic rhinitis ( hay fever ), food allergies, urticaria/angioedema (hives/swelling), immunodeficiency diseases, and autoimmune diseases. Eligibility: - Patients between the ages of 1 and 80 years who have been referred by a physician and are known to have or be suspected of having an inherited disorder of mast cells, in particular patients (and their relatives) with piebaldism, allergies, or anaphylaxis that is not caused by allergies. Design: - Study population will consist of up to 1000 participants in a 5-year period. One third of the study population will consist of patients; the other two thirds will consist of biological relatives. - Evaluation is limited to testing on blood specimens; no treatment will be provided. - Clinical and research laboratory evaluations of patients will include the following: - Clinical evaluation and previous laboratory tests as documented in outside medical records by health care providers. A standard questionnaire will also be administered at the time of subject enrollment. - Blood collection for clinical laboratory testing, tailored to each subject s clinical evaluation where appropriate (5 ml). - Blood collection for research laboratory testing, tailored to each subject s clinical evaluation including genetic screening and assessment of mast cell growth and functioning and storage of additional frozen blood specimens for future studies (up to an additional 30 ml). - Evaluations of blood relatives will include the following: - Clinical evaluation as documented from outside medical records by health care providers and administration of a standard questionnaire. - Blood collection where indicated for diagnostic or research purposes. - After 12 consecutive months on the study, results from initial evaluation will be reviewed. Subjects with findings deemed to be of continued interest will be contacted and invited to remain as active participants to this protocol for another year, provided that they renew their consent to participate.
