Amiloride Hydrochlorothiazide as Treatment of Acute Inflammation of the Optic Nerve
Optic; NeuritisWith DemyelinationFollowing acute inflammation of the optic nerve region, as commonly seen in multiple sclerosis patients, the optic nerve often undergoes atrophy, thus representing permanent damage. Data from animal studies suggest that amiloride may prevent this process. The aim of this study is to assess a potential neuroprotective effect of amiloride in acute autoimmune inflammation of the optic nerve region.

Contrast-enhanced 3D T1-weighted Gradient-echo Versus Spin-echo 3 Tesla MR Sequences in the Detection...
Magnetic Resonance ImagingCentral Nervous System3 moreGadolinium-enhanced magnetic resonance imaging (MRI) is currently the imaging gold standard to detect active inflammatory lesions in multiple sclerosis (MS) patients. The sensitivity of enhanced MRI to detect active lesions may vary according to the acquisition strategy used (e.g., delay between injection and image acquisition, contrast dose, field strength, and frequency of MRI sampling). Selection of the most appropriate T1-weighted sequence after contrast injection may also influence sensitivity. Several clinical studies performed at 1.5 Tesla have shown that conventional 2D spin-echo (SE) sequences perform better than gradient recalled-echo (GRE) sequences for depicting active MS lesions after gadolinium injection. As relates to MS, 3.0 Tesla systems offer some advantages over lower field strengths, such as higher detection rates for T2 and gadolinium-enhancing brain lesions, an important capability for diagnosing and monitoring MS patients. Recent studies have shown that at 3 Tesla, 3D GRE or 3D fast SE sequences provide higher detection rates for gadolinium-enhancing MS lesions, especially smaller ones, than standard 2D SE, and better suppress artefacts related to vascular pulsation. However, the comparison of the performance of 3D GRE versus 3D SE sequences has not been investigated yet. Objectives To compare the sensitivity of enhancing multiple sclerosis (MS) lesions in gadolinium-enhanced 3D T1-weighted gradient-echo (GRE) and turbo-spin-echo (TSE) sequences.
CSF Free Kappa Light Chain for The Diagnosis of Demyelinating Disorders
Multiple SclerosisMultiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS) which commonly leads to disability. The current preferred clinical laboratory test for the diagnosis is the detection of oligoclonal bands (OCBs) in the cerebrospinal fluid (CSF) by isoelectric focusing electrophoresis (IEF) followed by immunoblotting.Measuring the levels of Kappa Free Light Chain (K-FLC) in CSF has been proposed as a potential alternative to the qualitative assessment of OCBs. The aim of this study is to validate and determine the diagnostic yield of K-FLC in CSF against OCBs via IEF as gold standard.
Pharmacological Recruitment of Endogenous Neural Precursors to Promote Pediatric White Matter Repair:...
Demyelinating DiseaseThe neural circuits in our brains require a layer of insulation in order to transmit signals in a rapid and efficient fashion. This insulation is called White Matter and is comprised of a specific type of brain cell called an oligodendrocytes. Damage to brain white matter occurs following injury and in disorders like Multiple Sclerosis and results in sensory, motor, and cognitive problems. Currently there are no effective medical therapies to promote brain repair and reduce disability following damage to white matter. In this project, we hope to change the situation by encouraging the brain itself to generate new oligodendrocytes and thus new white matter. Our first step is to find measures sensitive to white matter growth.
Pathologic-MRI Findings in Atypical IIDD
Idiopathic Inflammatory Demyelinating Disorders of the Central Nervous SystemOur objective is to describe the pathologic and MRI findings in a series of patients with presumed demyelinating lesion of the central nervous system.
Oligodendrocyte Progenitor Cell Culture From Human Brain
Demyelinating DiseasesRecent developments in the understanding of stem- and progenitor cell differentiation raises hopes that brain damage in chronic neurological diseases may become repaired by systemic or focal transplantation of such cells. Clinical trials of stem- or progenitor cell transplantation in multiple sclerosis are currently premature. The researchers developed a protocol for human oligodendrocyte progenitor cell culture from human brain for the treatment of demyelinating disease.
Humoral and T-Cell Responses to COVID-19 Vaccination in Multiple Sclerosis Patients Treated With...
Multiple SclerosisDemyelinating Autoimmune Diseases7 moreThe primary goal of this study is to provide additional data regarding B and T-cell mediated responses to COVID-19 vaccines in MS patients treated with OCR and to determine which clinical and paraclinical variables correlating with vaccine immunogenicity. B-cell mediated humoral responses and adaptive T-cell mediated cellular responses were measured in patients treated with OCR who received any of the available SARS-CoV-2 vaccines, 3-4 weeks after completion of vaccination.
