Filter by:Neuromyelitis optica (NMO) is an inflammatory disease of the central nervous system that is associated with autoantibodies to aquaporin-4. Treatment options for prevention of clinical relapses of NMO include immunosuppressive medications. Plasma exchange (PLEX) is commonly used as a rescue therapy for NMO relapses but ongoing, regular PLEX procedures (maintenance PLEX) is sometimes used to prevent relapses. This observational registry will record feasibility, tolerability, safety, and preliminary efficacy data regarding maintenance PLEX for NMO.
Transverse myelitis is an inflammatory disorder of the spinal cord that leads to disabilities of gait. Dalfampridine, a sustained-release potassium channel blocker that has been shown to be effective in improving gait and other neurologic functions in multiple sclerosis. Dalfampridine has the potential to improve gait and neurologic function in patients with transverse myelitis as this rare disorder shares a similar pathogenic process with multiple sclerosis. The investigators propose a clinical trial to test the efficacy of dalfampridine in this particular cohort of patients. The clinical trial that the investigators propose to conduct will focus on monophasic idiopathic Transverse Myelitis (TM) and will evaluate the efficacy of dalfampridine in primary neurologic outcome, 25-foot timed walk, and several secondary outcomes including valid behavioral and neurophysiological measures. To better understand the mechanisms underlying the proposed behavioral gains, the investigators will use Transcranial Magnetic Stimulation as the neurophysiologic measure to identify changes in corticomotor excitability in the spinal cord.
This research is being done to see how different amounts of Functional Electrical Stimulation (FES) affect cycling on factors in blood and spinal cord in people with spinal cord inflammation.
Under normal conditions our immune system protects us against infections and tumors. The immune system does this by recognizing that the infecting organism or the tumor is foreign to the body and attacking it. One way the immune system attacks a foreign target is by making proteins called antibodies that bind to the target. Sometimes, for reasons we poorly understand, the immune system wrongly identifies part of our own body as being foreign and attacks it. This can result in disease such as some forms of diabetes and thyroid disease, as well as some neurological diseases. In this study, one tablespoon of blood will be removed from each subject and tested to see if the immune system is making antibodies against components of the nerves and muscles. We also hope to learn if these antibodies contribute to the development or worsening of illnesses of the nervous system. Only one blood draw is required, but subjects may be asked to give up to 8 additional blood samples to see if the level of antibodies changes over time. Any additional blood draws would be performed at regularly scheduled clinic visits. There would be at least 3 months between blood draws over a period of up to 3 years, if requested by the physician. Depending on your diagnosis, the physician may also request the collection of mouth (buccal) cells. This takes about one minute and is painless. The cells are collected by swishing a swab around your mouth. This cheek swab would be done with each blood draw. Please note that this study is conducted ONLY at UC Davis and that all participants must be seen in our clinic located in Sacramento, CA. Results of the testing performed in this study are not given to the participants. This study is not intended to treat or diagnose any condition.
To establish a large, longitudinal collection of high quality samples and data from subjects with MS, selected other demyelinating diseases (Transverse Myelitis (TM), Neuromyelitis Optica (NMO) or Devic's, Acute Disseminated Encephalomyelitis (ADEM), and Optic Neuritis (ON)), and related and unrelated unaffected controls. Samples and data will be available as a shared resource to scientists researching the causes, sub-types, and biomarkers of MS and related demyelinating diseases.
Neuromyelitis optica (NMO) is a severe demyelinating disease that selectively involves the optic nerves and the spinal cord but usually spares the brain. NMO is considered to have a B cell induced pathogenesis. Mitoxantrone (MITO, Novantrone®), a synthetic anthracenedione approved for worsening relapsing-remitting multiple sclerosis (MS) and secondary progressive MS, has been shown to primarily suppress the humoral response. We conducted a prospective 2-year study to evaluate the benefit of MITO in five relapsing NMO patients.
The current study is an extension of the previous phase III CHAMPS study (see reference). This study was designed to determine if immediate initiation of therapy with Interferon Beta-1a (AVONEX) after a first attack of multiple sclerosis continues to delay the development of further attacks and the development of neurological disability over a 10 year period of observation.
This study will examine how West Nile virus (WNV) infection affects the body. Some people infected with WNV have no symptoms. In others, symptoms may vary from fever and headache to a polio-like syndrome with paralysis, to coma and brain changes like those of a stroke. Many patients recover with no lasting effects, while a few can have long-lasting neurological damage or may die. This study will collect clinical, laboratory, diagnostic, and radiographic information on people thought to have WNV to better understand the disease. Patients 18 years of age and older diagnosed with or suspected of having West Nile virus infection may be eligible for this study. Patients will be hospitalized until they are well enough to go home and will undergo the following tests and procedures: - Medical history and physical examination: A thorough history and physical examination will be done on the first day of the study. Then, brief physical exams, including measures of blood pressure, heart rate, breathing rate, and temperature, will be done during each day of hospitalization and at every follow-up clinic visit (at 2 weeks and at 1, 3, and 6 months). - Blood tests: Blood samples will be collected on the first day of the study, at day 7, at hospital discharge, and at follow-up visits to determine if virus remains in the blood and how it is affecting the body. - Magnetic resonance imaging (MRI): MRI scans will be done within 72 hours of beginning the study and 1 month after that. This test uses a strong magnetic field and radio waves to produce images of the brain that might show abnormalities in the brains of patients with WNV and reveal whether the abnormalities can predict how an individual will recover. For the procedure, the patient lies on a table that is moved into the narrow tunnel-like scanner. During the procedure, a contrast agent that brightens the images is injected through a catheter placed in an arm vein. - Neurological examination and neurological function tests: Participants will be tested to see if the West Nile virus has affected their thinking and ability to perform normal daily activities. These tests will be done at the start of the study, on days 3 and 7 (also days 2, 4, 5, and 6 if patients are still in the hospital), at discharge, and at follow-up visits. The tests involve answering a number of questions and performing simple tasks, such as squeezing a hand or lifting a foot. - Patients who develop weakness in their arms or legs will also have the following studies: 1. Electromyography (EMG) to study the electrical activity of the muscle. For this test, needles are placed into a muscle to record the electrical activity at that site. 2. Nerve conduction studies to measure how well the nerves are working. A small charge of electricity is delivered to a nerve in the affected limb, triggering a muscle to tighten or bend. Small wire electrodes are attached to the skin to measure the time is takes for the nerve to move the electrical current from one part of the limb to another. 3. Spinal MRI to see if the virus is affecting the spinal cord. Results of other tests done by the patient's local doctor (such as lumbar puncture, electroencephalogram, x-rays, etc.) will be requested. If a lumbar puncture is done, a small amount of cerebrospinal fluid will be requested for testing for WNV.
The participant will receive weekly intramuscular treatment with AVONEX® (interferon beta 1-a) and a one-time high dose intravenous methotrexate with Leucovorin rescue, along with the standard solumedrol treatment before beginning AVONEX® treatment.
OBJECTIVES: I. Evaluate the effectiveness of plasma exchange in the treatment of acute severe attacks of inflammatory demyelinating disease in patients who have failed intravenous steroid therapy.
