The aim of this study was the describe the Immunologic biomarker profile of cerebrospinal fluid in multiple sclerosis patients
Central Nervous System (CNS) demyelinating conditions include multiple sclerosis (MS), Acute Disseminated Encephalomyelitis (ADEM), Neuromyelitis Optica Spectrum Disorder (NMOSD), Optic Neuritis (ON) and Transverse Myelitis (TM). The symptoms of these conditions are quite variable from patient to patient, but can include motor, sensory, visual, gait and cognitive changes. Conventional MRI can be used to look for new anatomic changes, but fails to measure underlying biochemical changes in brain tissue. The purposes of this study are to identify the biologic and anatomic correlations between cognitive profiles and disease activity using MRI imaging techniques.
Neuromyelitis Optica Spectrum Disorders (NMOSD) are a group of inflammatory demyelinating disorders of the central nervous system. Although NMOSD occurs much more commonly in nations with a predominately non-Caucasian population, NMOSD are underestimated in Egypt and frequently misdiagnosed as multiple sclerosis (MS). In this study, by investigating serum anti-aquaporin (AQP) 4 and anti-MOG antibody of patients suspected to have NMOSD attending the Neurology and Psychiatry department of Assiut University Hospital, investigators aim to determine the relative frequency, clinical and radiological characteristics of NMOSD in upper Egypt community and compare it with other populations of different races.
This study is being done to develop a database of pediatric patients in order to study the cause, early detection and best treatment for neuromyelitis optica spectrum disorder (NMOSD) in pediatric patients.
A novel technology called Scrambler Therapy is a non-invasive pain modifying technique that utilizes transcutaneous electrical stimulation of C fibers with the intent of re-organizing maladaptive signaling pathways. This neuromodulatory therapy has been investigated for treatment of chronic neuropathic pain in several conditions including chemotherapy-induced peripheral neuropathy, post-herpetic neuralgia and post-surgical neuropathic pain with promising results. Patients report sustained relief after undergoing daily treatment sessions for 10 consecutive weekdays. This study is a randomized single blinded, sham-controlled trial of patients with Neuromyelitis Optica Spectrum Disorder who have central neuropathic pain using Scrambler Therapy added to standardized empiric medications using patient reported outcomes to determine if Scrambler Therapy is a feasible and effective add-on treatment of chronic neuropathic pain. This trial will recruit twenty-two adult patients diagnosed with NMOSD who have chronic neuropathic pain despite empiric treatment with an anti-epileptic, antidepressant, opioid and/or an NSAID medication. Patients will be randomized 1:1 to undergo Scrambler Therapy or blinded sham daily for 10 days. The primary outcomes will be acceptability and feasibility. The secondary outcome will be efficacy measured as a change in pain scores of more than two points recorded daily by the patient using an 11-point visual analog scale; quality of life (QoL), neurologic function, anxiety, depression, sleep disturbance and pain will also be evaluated at baseline, at the end of therapy, and at 4 & 8 weeks following completion of treatment. Investigators hypothesize that Scrambler Therapy will be an acceptable, feasible and efficacious intervention that significantly reduces pain in patients with neuromyelitis optica spectrum disorder.
In neuromyelitis optica spectrum disorder (NMOSD),interleukin-6 (IL-6) may play an important role in facilitating plasma cells to produce pathological aquaporin 4 (AQP4) autoantibody. Inhibition of IL-6 signaling pathway by Tocilizumab (ACTEMRA®), a humanized monoclonal antibody may have shown beneficial clinical effects in a few patients with NMOSD. Larger scale clincial trials may be needed to observe its efficacy and safety. Here, by choosing azathioprine, one of the most frequently used medication in case of relapses, the investigators compare the safety and efficacy of tocilizumab in preventing NMOSD attacks.
This study will determine the safety and tolerability of ABX-1431 in patients with central pain when added on to background pain therapy. During the course of this study, each participant will take a daily dose of 20 mg of ABX-1431 or a matching placebo for approximately 7 to 9 weeks.
Neuromyelitis Optica Spectrum Disorder (NMOSD) is a severe inflammatory disease of the central nervous system characterized by relapsing optic neuritis and longitudinal extensive transverse myelitis. The specific autoantibody against aquaporin 4 (AQP4-ab) has been suggested to contribute to the pathogenesis of the disease. Peripheral blood plasma cells are a major source of AQP4-ab. Previous studies have observed increased IL-6 levels in serum and cerebrospinal fluid of patients with NMOSD, particularly during relapses. Exogenous interleukin (IL)-6 promotes the survival of plasma cells and their production of AQP4-ab in vitro. And blockade of IL-6 receptor signaling by an anti-IL-6 receptor antibody reduces the survival of plasma cells in vitro. Tocilizumab (ACTEMRA®), a humanized monoclonal antibody against the IL-6 receptor, has shown beneficial clinical effects in some patients with NMOSD when concomitant immunosuppressive medications were administered. However, the long-lasting biological effects of preceding immunotherapies such as rituximab might overlap with the subsequent tocilizumab therapy. To reduce the side effects of concomitant treatments to large extent and verify the beneficial effects of tocilizumab, we evaluate the safety and efficacy of tocilizumab as monotherapy in patients with NMOSD.
The purpose of this study is to compare annual relapse rate, expanded disability status scale, and side effects of azathioprine and rituximab in patients with neuromyelitis optica spectrum disorder during a one year follow up through a randomized clinical trial.
