Filter by:The investigators hypothesize that hypogammaglobulinemia (defined as IgG serum concentration <7.0g/L) is a treatable cause of fatigue in people with MS: The primary objective is to prove the link between hypogammaglobulinemia and fatigue in patients with multiple sclerosis. The secondary objective is to show that fatigue is mediated via frequent infections in people with MS and hypogammaglobulinemia.
People with Parkinson's disease and Multiple Sclerosis experience disabling motor and non-motor symptoms, which respond insufficiently to medication. To adequately alleviate disease burden, physical training is increasing acknowledged as an assisting therapy; however, the optimal dose of exercise in unknown.
The primary goal of this project is providing evidence that a home-based combined cognitive-motor training program improves cognition in persons with multiple sclerosis (MS), compared to single cognitive and motor rehabilitation. Secondary goals are to assess the effects on walking performance and to identify the mechanisms of improvement and predictors of treatment response. The main backbone of this project will be a randomized controlled two-centre clinical trial, in which an at-home computerised cognitive-motor rehabilitation program using telemedicine aimed at improving working memory in persons with MS will be evaluated. Based on the information gathered during this trial, possible mechanisms of improvement will be identified by analysing anatomical and neurophysiological changes on structural MRI and resting-state and task-related EEG before and after rehabilitation. Furthermore, factors that can predict treatment response to the rehabilitation program will be identified.
Amyotrophic lateral sclerosis (ALS) is a rare neuromuscular disease that occurs in adults. It is characterized by a progressive degeneration of the first and second motor neurons leading to muscle failure. In its spinal form, ALS manifests by a progressive worsening of limb involvement, whereas the bulbar form presents with swallowing disorders, dysarthria and feeding difficulties. Respiratory impairment is the most serious feature of ALS. Phrenic nerve damage causes diaphragmatic weakness, which inevitably leads to chronic restrictive respiratory failure. At the stage of symptomatic nocturnal or diurnal alveolar hypoventilation, non-invasive ventilation (NIV) prolongs survival while improving quality of life by relieving respiratory symptoms. The indication for the initiation of NIV is based on the appearance of respiratory symptoms but also on the demonstration of diaphragmatic insufficiency. A quarterly follow-up of diaphragmatic function has been recommended by the French Health Authority since 2006. It is based on functional respiratory explorations (VC in sitting and lying position, measurement of maximal inspiratory pressure) and screening for diurnal or nocturnal hypoventilation with the measurement of PaCO2 or the nocturnal recording of SpO2. Access to these examinations remains limited and they are sometimes complex to perform (in particular issues with mouth occlusion during respiratory manoeuvres in case of bulbar damage). Thus, only 60% of patients undergo a complete evaluation. Moreover, these explorations are only late markers of diaphragmatic dysfunction, and it has recently been shown that they do not correlate with histological diaphragmatic amyotrophy. The development of new, reliable, and easily available tools for the evaluation of diaphragmatic function, and that are capable of detecting diaphragmatic insufficiency early in the course of the disease, are therefore necessary. Such tools would make it easier to implement NIV at the optimal time, preventing episodes of acute respiratory distress. Recently, diaphragmatic ultrasound has appeared in the ICU as a new tool for assessing diaphragmatic function. It has the advantage of being highly available, inexpensive, non-irradiating, quick to perform, reproducible and very sensitive and specific for the diagnosis of diaphragmatic dysfunction. In ALS, few studies have investigated the contribution of ultrasound for the diagnosis or follow-up of diaphragmatic dysfunction. In addition, no study so far has compared diaphragmatic ultrasound to complete pulmonary function test (PFT) data or to direct measurement of diaphragmatic pressure (Pdi). Very few publications report the how the diaphragm changes on ultrasound imaging during the disease. Moreover, these studies do not analyse the interest of diaphragmatic ultrasound in the prediction of progression towards respiratory failure with respiratory support, or death. Finally, these studies use different ultrasound measurements of the diaphragm (stroke, thickness, thickening fraction, and thickening fraction ratio, among others) rather than a simple, consensual parameter. The aim of this study is to describe the evolution of diaphragmatic ultrasound parameters, to identify the parameter that best correlates with other respiratory measures (PFT, PaCO2, nocturnal oximetry) and to determine the prognostic value of diaphragmatic ultrasound in predicting the initiation of NIV or death at 6 and 12 months.
The purpose of this study is to assess the safety of metformin for treatment of progressive multiple sclerosis
Systemic sclerosis (SSc) is a heterogeneous systemic autoimmune disease with distinct prognosis according to patients. In patients with systemic sclerosis, interstitial lung disease (ILD) concerns almost 50 % of patients and represents the main cause of mortality. Disease course in SSc-ILD is highly variable: patients can experience stable disease, slow or fast progression. Prevention of ILD progression now represents a key objective of SSc-ILD management. The understanding of the course and patterns of SSc-ILD progression is necessary, as reliable prediction tools that allow the stratification of the risk of progression. We aimed to identify the longitudinal trajectories of ILD in SSc patients using latent class mixed models and to examine their associations with SSc characteristics.
This is an observational, non-interventional, multicenter, open-label study in patients being treated with any approved injectable Disease-modifying Therapy (DMT) for Relapsing Multiple Sclerosis in Germany. Prospective, primary data will be collected via questionnaires and an electronic case report form (eCRF) over a period of up to approx. two years of treatment. Additionally, medical history of participants will be collected including disease duration, EDSS, MRI parameters and relapses.
Multiple Sclerosis (MS), a chronic inflammatory disease of the central nervous system, is a disease characterized by myelin, oligodendrocyte and axon damage. Research continues on the autoimmune, infectious, environmental, vascular and genetic origins of this disease, which affects approximately 2.5 million people in the world and is seen 2-3 times more in women than in men. Although the signs and symptoms of the disease vary according to the location of the lesion; frequently, loss of strength, spasticity, sensory disturbances, fatigue, ataxia, autonomic dysfunction, and decreased visual acuity are observed. With these approaches, the effect of Kinesiotape application on balance will be investigated in individuals with ataxic MS. Based on this idea, our work; It was planned to investigate the effect of kinesiotape application on balance in individuals diagnosed with ataxic multiple sclerosis.
In ALS models, it was shown that receptors, that bind an important messenger substance (glutamate) in the brain, are increased. In this research project, the investigators want to use a specific radioactive substance to find out whether these receptors are more detectable in people with ALS than in healthy people and increase over the course of the disease.
Rationale: Clemastine fumarate has been identified as potential remyelinating therapy for multiple sclerosis (MS). The (long-term) effects of clemastine need to be confirmed in clinical models for MS. Internuclear ophthalmoparesis (INO) may be used as a clinical model for investigating remyelinating therapies by measuring horizontal eye movements with infrared oculography. Furthermore, infrared oculography combined with a single dose of fampridine may be used to identify individuals with MS that are most likely to benefit from remyelinating therapy. Objective: To assess the (long-term) efficacy of clemastine fumarate in improving dysconjugacy of eye movements in patients with internuclear ophthalmoparesis and multiple sclerosis. Secondly, to assess whether a response to a single dose of fampridine can predict the effects of clemastine treatment. Study design: A single-centre double-blind randomized placebo-controlled trial consisting of a 6 months (180 days) treatment period followed by a 30 months follow-up period. Study population: 80 MS patients, age 18-70 years, with INO. Intervention: The intervention group will receive 4 mg of clemastine fumarate twice daily (8 mg/day) for 6 months (180 days), the control group will receive an equivalent amount of placebo. At baseline all participants will receive a single 10 mg dose of fampridine. Main study parameters/endpoints: The primary outcome measure is the change in versional dysconjugacy index (VDI) of area under the curve (AUC) measured by infrared oculography. Secondary outcome measures include changes in other VDI measures (peak velocity per amplitude (PV/Am) and peak velocity (PV)), changes in VDI after single fampridine dose, other oculography parameters (e.g. saccadic latency, anti-saccades), (peripheral) retinal nerve fibre layer (pRNFL) and (macular) ganglion cell inner plexiform layer (mGCIPL) thickness measured by OCT, SDMT, EDSS, high and low contrast visual acuity, subjective visual functioning (NEI-VFQ-25 and NOV-AU questionnaire), quality of life (EQ5D-5L) and fatigue (CIS20R and NFI-MS questionnaire). Nature and extent of the burden and risks: Participation in the study will consist of a total of 7 study visits. Study visits will include physical/neurological examination, infrared oculography, OCT, visual acuity tests, a cognition test (SDMT), 5 questionnaires and blood samples for safety laboratory tests. Considering both clemastine and fampridine are registered and well-established drugs and have been used in clinical practice, the estimated risk of unexpected adverse reactions is low.
