Active clinical trials for "Multiple Sclerosis"

This project aims to contribute knowledge to early MS disease mechanisms at the brain-blood interface using a combined immunological and neuroimaging approach. The aim is to provide a novel vascular model to assess MS disease activity, and to explore its potential as an early diagnostic biomarker, prior to blood-brain barrier disruption. Additionally, the investigators want to investigate influence of immune receptor defects upon disease activity and MS brain vascular system. These aims are addressed by investigating immune receptor signals and vascular imaging modalities acquired in newly diagnosed untreated MS cohort, followed at our institution.

Using an automatic software tool, Pixyl.Neuro, to conduct a retrospective analysis (detection of lesions + segmentation of images + tracking over time) of cerebral MRI images acquired during a prospective study of patients presenting with clinically isolated syndrome, and comparing the results against manual analysis.

The main aim of the present study is to assess the prevalence, the topography and the clinical counterpart of cortical lesions in patient included early after the first clinical episode of multiple sclerosis. A second aim is to assess the direct contribution of cortical lesions - independent of WM injury - on the diffuse grey matter damage. Thirty MS patients will be included in the six months after the first clinical episode of multiple sclerosis for a monocentric transversal MRI study at 7T to assess cortical MS injury. Clinical (EDSS) and neuropsychological assessments will be performed in the population the same day of a multi-parametric MRI. MRI protocol is designed to increase the detection rate of CL using multiple contrasts at high isotropic resolution (600µm3) on a whole brain exploration. Thus, MRI acquisition will include MP2RAGE, T2*, FLAIR and DIR as previously published but also recent MRI technique like FLAWS, focusing on the grey matter by attenuating the white matter and CSF signal. Finally, QSM sequences will be performed. QSM measures tissue magnetic susceptibility mostly influenced by iron, myelin and calcium content in the brain. Due to physical properties of the technique (bipolarity), we suppose that high resolution QSM will be more sensitive that previous used sequences to depict cortical lesions. Using this multi-contrast approach with relevant MRI sequence and with a high resolution whole brain exploration might improve the detection of CL in early MS. Furthermore, MRI protocol allow us to estimate neuronal loss (T1 relaxation time), myelin and iron content (QSM and T2* relaxation time) within and outside cortical lesions in GM. The present study is an opportunity to assess cortical pathology in MS from the onset of the disease, allowing to a better understanding of its origins and its impact and disease severity. This study is a preliminary requirement to longitudinal studies to precisely depict the kinetic of cortical lesion accumulation and the links with disease aggravation.

The study aimed to provide insights in the coordination between trunk, shoulder and upper limb while reaching. Two main phases are present in this study: In phase A: the psychometric properties of two tests: Clinical Scapular protocol (ClinScaP) in PwMS (Persons with Multiple Sclerosis) and healthy controls. To investigate the test-retest reliability of the Clinical Scapular Protocol (ClinScaP) and the Reaching Performance Scale (RPS) in PwMS To investigate the discriminative of the ClinScaP between PwMS and healthy controls To investigate the discriminative of the RPS between PwMS and healthy controls To investigate the concurrent validity of ClinScaP and RPS in PwMS, compared with upper limb dysfunction measurements. In phase B: To investigate the prevalence of trunk, scapula and upper limb impairments in PwMS and stroke patients. To investigate the interaction between trunk, scapula and upper limb impairments in PwMS and stroke patients.

Balance and gait disturbances are among the most common problems in patients with Multiple Sclerosis (MS). There is evidence of decreased foot sole sensation in MS patients. Studies conducted in healthy individuals have revealed the relationship between balance and foot sole sensation. These studies have demonstrated that sensory feedback from the cutaneous receptors of the foot sole plays an important role in maintaining balance. However, it is not yet known clearly to what extent the sensory impairment seen in MS patients affects balance and gait disorders. The aim of this study is to examine the relationship between lower extremity position sense and foot sole sense with gait and balance in MS patients.

This study series consists of four related studies and aims to explore and describe many important elements of alopecia areata over three key areas: (1) the current epidemiology of alopecia areata, (2) the prevalence and incidence of psychiatric co-morbidities in people with alopecia areata, (3) the prevalence and incidence of autoimmune and atopic conditions in people with alopecia areata, and (4) the incidence of common infections in people with alopecia areata.

The primary objective(s) of the study is to evaluate the impact of exposure to SC Peginterferon beta-1a or IM Interferon beta-1a before and during pregnancy on pregnancy outcome in female participants who had registered in the German Patient Support Program (PSP) and of whom a pregnancy report and pregnancy outcome report is available. The secondary objectives of this study are applicable for a subpopulation of the above-mentioned population, i.e. for participants of whom data on a standardized questionnaire collected during a telephone interview is available.

Unemployment is particularly common among women with multiple sclerosis (MS). This study uses a vocational rehabilitation program involving neuropsychological testing as an intervention. The use of in-person feedback and case management following neuropsychological testing is compared to phone feedback only. Adherence to treatment and employment outcomes will be evaluated over three years.

The overarching aim is to assess the role of microglial activation and norepinephrine transporter binding in pathogenesis of MS-related fatigue, using novel Positron Emission Tomography (PET) radiotracers, [F-18]PBR06 and [C-11]MRB. Specific Aims: Specific Aim 1: To determine the relationship of cerebral microglial activation, as assessed by [F-18]PBR06 PET, with MS-related fatigue. Specific Aim 2: To determine the relationship of norepinephrine transporter (NET) binding, as assessed by [C-11]MRB PET, with MS-related fatigue. Specific Aim 3: To determine the relationship of microglial activation and NET binding, with grey matter pathology (lesion load and brain atrophy) assessed using 7T MRI, and evaluate their independent contribution in development of MS-related fatigue.

This project aims to analyse eye movements, their alterations and influence in reading performance in patients with acquired CNS diseases and compare them with people of the same age, without neurological or ocular pathology and with normal reading speed and pattern. The exploration is focused on the oculomotor system in patients with CNS diseases, even without involvement of the primary visual pathway, and reveals more involvement than the one obtained by a simple ophthalmological examination.
