Filter by:This study will evaluate the use of autologous bone marrow derived stem cells (BMSC) for the treatment of retinal and optic nerve damage or disease.
Patients who are genetically diagnosed with the recently reported and rare Wolfram syndrome type 2 ( WFS2) and have the degenerative and symptomatic disease including signs such as diabetes, platelet aggregation defect or visual problems will be asked to participate in this study. Knowing the pathomechanism of WFS2 with rapid cell death, after doing baseline investigations to asses the severity of their disease, the participants will be offered a chelator therapy with in addition to the antioxidant Acetylcystein, in diabetic patients an Incertin (GLP-1 ) therapy will be offered as well. The baseline investigations will be repeated after 2 months and after 5 months of therapy in order to asses the progression of the disease and to show if the chelator and anti oxidant therapy and in diabetic patients the GLP-1 therapy could stop the progression of the disease.
In this study, the investigators hypothesize that studying monogenic variants with strong effect associated with severe insulin deficiency of Wolfram syndrome will provide important insights into the more complex type 1 and type 2 diabetes mellitus. Aim 1. Establish and maintain a registry of patients with Wolfram syndrome. An Internet based registry will be employed to enroll participants with the clinical diagnosis of Wolfram syndrome (insulin dependent DM and bilateral OA). Clinical information regarding age of diagnosis and progression of the disease will be collated and analyzed to better define its natural history, along with potential metabolic phenotypes such as glucose intolerance of heterozygous parents and unaffected sibs. If not already completed, blood for WFS1 sequence analysis will be obtained on the participants (parents and sibs also for control purposes) and sent to a CLIA certified lab to define the mutation. This information will benefit patient families and referring physicians by providing a genetic diagnosis and where indicated. The Wolfram Syndrome Registry will foster international collaborations to more efficiently and systematically collect Wolfram syndrome patients and their clinical and experimental data.
Wolfram syndrome is a rare genetic disorder characterized by juvenile-onset diabetes mellitus, diabetes insipidus, optic nerve atrophy, hearing loss, and neurodegeneration. The purpose of this study is to assess the safety and tolerability of dantrolene sodium in patients with Wolfram syndrome. In addition, we will assess the efficacy of dantrolene sodium on the cardinal manifestations of Wolfram syndrome, including visual acuity, remaining beta cell functions, and neurological functions. There is a screening period up to 56 days, a 6-month treatment period with an optional extension phase up to 24 months, and a 4-week safety follow-up period. Study assessments include medical & medication history, physical exams, neurological exams, eye exams, endocrine exams, vital signs, height, weight, electrocardiograms, blood and urine tests, pregnancy test if applicable, and questionnaires.
This is a Single arm, Single centre trial to check the safety and efficacy of bone marrow derived autologous mono nuclear cell(100 millions per dose )clinical trial to be conducted for 36 months in patients with optic nerve diseases.
CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.
The purpose of this study is to determine the anatomy of the retina and the optic nerve in patients with autosomal dominant optic atrophy (ADOA). Based on these findings the aim of the study is to determine why patients with the same type of genetic material, i.e. the same mutation, have such large variations of symptoms, spanning from unaffected subjects to blindness. The project requires examination of both healthy and affected family members.
This is an open-label, dose escalation, safety, tolerability and pharmacokinetic study, where active study drug (QPI-1007) will be given to all patients who participate. This study will determine whether QPI-1007 is safe when it is injected into the eye. The study will also reveal if there are any side effects of the drug and how long it takes for the body to clear the drug.
Transcorneal stimulation may enable neurons to survive degeneration processes via enhanced secretion of neurotrophic substances and direct stimulation of neurons.
Background Leber's Hereditary Optic Neuropathy (LHON) is a maternally inherited ocular disorder associated with a mutation in mtDNA . The common manifestation is visual loss which caused by the respiratory chain enzymes complex dysfunction resulting in increased oxidative stress enzymes production. Purpose To determine whether curcumin which is an antioxidant agent is beneficial to the patients with 11778 LHON mutation. Material and Method Seventy patients with 11778 LHON mutation were randomly treated with oral curcumin (500 mg/day) and placebo for 1 year. The visual acuity, computerized visual field, electrophysiologic parameters and oxidative stress enzymes in plasma were compared before and after treatment at 3, 6, and 12 months interval.
