Filter by:The purpose of the project is to investigate how aerobic exercise affects brain volume, specific brain regions, neurotrophins and cognition in patients with multiple sclerosis. The study will be a single blinded randomized controlled trial with a 6 months intervention. It is hypothesized that aerobic exercise can slow down brain atrophy, increase the size of hippocampus, upregulate the secretion of neurotrophins and improve cognitive performance in people with multiple sclerosis.
The purpose of this study is to determine whether Tcelna (imilecleucel-T, autologous T-Cell Immunotherapy) is effective in the treatment of secondary progressive multiple sclerosis (SPMS).
Study description: This is a natural history study that will evaluate any patient with enzyme or DNA confirmed GM1 or GM2 gangliosidosis, sialidosis or galactosialidosis. Patients may be evaluated every 6 months for infantile onset disease, yearly for juvenile onset and approximately every two years for adult-onset disease as long as they are clinically stable to travel. Data will be evaluated serially for each patient, and cross-sectionally for patients of similar ages and genotypes. Genotype-phenotype correlations will be made where possible although these are rare disorders and the majority of the patients are compound heterozygotes. Objectives: To study the natural history and progression of neurodegeneration in individuals with glycosphingolipid storage disorders (GSL), GM1 and GM2 gangliosidosis, and glycoprotein (GP) disorders including sialidosis and galactosialidosis using clinical evaluation of patients and patient/parent surveys. To develop sensitive tools for monitoring disease progression. To identify biological markers in blood, cerebrospinal fluid, and urine that correlate with disease severity and progression and can be used as outcome measures for future clinical trials. To further understand and characterize the mechanisms of neurodegeneration in GSL and GP storage disorders across the spectrum of disease beginning with ganglioside storage in fetal life. Endpoints: Exploring the natural history of Lysosomal Storage Diseases and Glycoprotein Disorders Study Population: Patients with enzyme or DNA confirmed GM1 or GM2 gangliosidosis, sialidosis or galactosialidosis. Accrual ceiling is 200 participants. No exclusions based on age, gender, demographic group, or demographic location. Patients included in our study are those that are seen at the NIH Clinical Center, subjects that have only sent in blood samples, as well as those who complete the questionnaire or provided head circumference measures.
