Filter by:The clinical project "Eight At One Stroke: Attention Gangliosidoses" represents a clinical registry for recording the clinical manifestation and the disease progression of gangliosidoses. The intention of this project is to better understand the manifestation and progression of gangliosidoses and to raise awareness of these disorders in the public health service. The patients or their families, respectively, will be integrated in the study in order to measure Patient Outcome and to objectify the psychosocial burden for the patient and his family. The study has a retrospective and a prospective part. It is planned to transfer the data of the study into a continuous registry.
GM2 gangliosidosis is an autosomal recessive subtype of Lysosomal Storage Diseases in which, Hexosaminidase A-B deficiency is caused by HEXA-B gene. HEXA deficiency is seen in Tay sachs and HEXB deficiency causes Sandhoff disease. Infantile forms of Sandhoff and Tay sachs are often lethal and management of the patients is supportive including nutrition, hydration, seizure control and management of respiratory problems. Recent studies have suggested new methods of treatment, such as enzyme replacement therapy, bone marrow transplantation and substrate reduction therapy. The first drug used in SRT was Miglustat. It was introduced in 1980 as an anti HIV agent and later, it was registered under the trademark of Zavesca in 2009 and was used in treatment of Gaucher and Niemann-Pick disease. Zavesca passes blood brain barrier, so causes reduction of cholesterol and glycosphingolipids CNS neurons and relief of neurologic manifestations. Improvements were seen in oculomotor function, cognition, swallowing, motor disturbances and psychological problems after treatment with Zavesca. No effect has been proved on visceral involvement. Weight loss during first year of treatment, diarrhea and dyspepsia are seen as side effects. Studies on SRT in lysosomal storage disease have different results. Some show improvements in manifestations of Gausche, Sandhoff & Tay sachs disease, while others show no valuable benefit for this method of treatment. Finding an effective treatment for these chronic diseases can improve quality of life for the patients and their families, and also reduce costs for healthcare services. The controversy persists and more studies are needed for judgment. So this study is done to evaluate the effect of Miglustat therapy in Sandhoff and Tay sachs disease, and is believed to help for further studies in this field.
The purpose of this study is to understand the course of rare genetic disorders that affect the brain. This data is being analyzed to gain a better understanding of the progression of the rare neurodegenerative disorders and the effects of interventions.
The Myelin Disorders Biorepository Project (MDBP) seeks to collect and analyze clinical data and biological samples from leukodystrophy patients worldwide to support ongoing and future research projects. The MDBP is one of the world's largest leukodystrophy biorepositories, having enrolled nearly 2,000 affected individuals since it was launched over a decade ago. Researchers working in the biorepository hope to use these materials to uncover new genetic etiologies for various leukodystrophies, develop biomarkers for use in future clinical trials, and better understand the natural history of these disorders. The knowledge gained from these efforts may help improve the diagnostic tools and treatment options available to patients in the future.
The primary objective of the study is to determine the safety and feasibility of intrathecal administration of DUOC-01 as an adjunctive therapy in patients with inborn errors of metabolism who have evidence of early demyelinating disease in the central nervous system (CNS) who are undergoing standard treatment with unrelated umbilical cord blood transplantation (UCBT). The secondary objective of the study is to describe the efficacy of UCBT with intrathecal administration of DUOC-01 in these patients.
Hypothesis: To characterize and describe disease progression and heterogeneity of the gangliosidosis diseases. This research study seeks to develop a quantitative method to delineate disease progression for the gangliosidosis diseases (Tay-Sachs disease, Sandhoff disease, and GM1 gangliosidosis) in order to better understand the natural history and heterogeneity of these diseases. Such a quantitative method will also be essential for evaluating any treatments that may become available in the future, such as gene therapy. The data from this study will be necessary to provide end-points for future therapies, guide medical decisions about treatment, provide objective measurement of treatment outcomes, and accurately inform parents regarding potential outcomes.
