Optic Coherence Tomography in Patients With Amyotrophic Lateral Sclerosis
Amyotrophic Lateral SclerosisAmyotrophic Lateral Sclerosis (ALS) is an adult-onset, devastating, neurodegenerative disease characterized by the loss of cortical, brain stem, and spinal motor neurons. Visual evoked potentials studies in patients with ALS suggest visual pathway involvement. Optic coherence tomography (OCT) is a non-invasive cross-sectional imaging modality measuring the optical reflections in biological tissues. The main objective of this observational cohort study is to explore the correlation between changes on OCT retinal parameters and and clinical disability as measured by the ALS Functional Rating Scale (ALS-FRS-r) in patients with ALS at baseline, 3 and 6 months. A secondary objective is to explore the correlation between changes in retinal OCT parameters and pulmonary function tests (FVC and FEV1) in this cohort of patients with ALS. A parallel cohort of healthy age and sex matched subjects will participate as controls to obtain reference values of their retinal layers' thickness at baseline, 3 and 6 months.
Hypermetabolism in ALS Using Six REE Formulas
Amyotrophic Lateral SclerosisIntroduction: About 50-60% of Amyotrophic Lateral Sclerosis (ALS) is characterized by hypermetabolism, defined as 10% or more excess resting energy expenditure (REE) compared to theoretical values. Harris and Benedict's (HB) formula is the equation mainly used to predict REE, but others are also applied in current practice. The present study aimed to assess REE in ALS patients compared to control populations and to compare six formulas commonly used to predict REE. Nutritional assessments were performed in ALS patients and in two control populations without hypermetabolism: healthy elderly people (control 1) and patients with non-restrictive-eating disorders (control 2). Weight, height and body composition (by bioimpedance analysis) were assessed. EE was measured (mREE) by indirect calorimetry and calculated (cREE) using HB 1919 and 1984, World Schofield, De Lorenzo, Johnstone and Mifflin formulas. Mann-Whitney and Chi2 tests were used to compare the equations.
Intermediate Expanded Access Protocol (EAP) CNMAu8.EAP02
Amyotrophic Lateral SclerosisThe primary objective of the intermediate expanded access protocol is to provide access to the investigational product, CNM-Au8, to up to 300 people living with ALS (pALS). No formal clinical hypotheses are being evaluated with concurrent controls. Secondary objectives include assessment of the safety of CNM-Au8 treatment in pALS. Safety will be assessed through the frequency of serious adverse events (SAEs), treatment-emergent adverse events (TEAEs) assessed as 'severe', discontinuations due to TEAEs, and laboratory abnormalities assessed as clinically significant during routine clinical monitoring (as applicable).

Clinical Factors Associated With Position Sense in Patients With Multiple Sclerosis
Multiple SclerosisSensory impairment is an important problem for patients with Multiple Sclerosis (MS). Although there is no complete loss of sensation in patients, 80% of patients have a significant sensory impairment. The sensory system plays an important role in providing the feedback required to perform motor tasks. Cutaneous sensation, especially in the sole of the foot, is very important in maintaining balance and gait. There are studies showing decreased foot sole sensation in MS patients. Another sensation that is important during motor tasks is the proprioceptive sensation. The aim of this study is to examine the relationship between the sensation of foot sole and joint position, clinical features, attention, fatigue, body awareness and physical activity level in patients with MS.
Novel Assessment of Synaptic Density in Progressive MS
Primary Progressive Multiple SclerosisSecondary Progressive Multiple Sclerosis2 moreThe investigators propose to use the novel SV2a-PET ligand, [F-18]SDM-8 to assess synaptic density in progressive MS (including primary progressive multiple sclerosis (PPMS) and secondary progressive multiple sclerosis (SPMS)) as compared to relapsing-remitting multiple sclerosis (RRMS) patients and healthy controls, given its improved imaging characteristics and potential for large scale applicability. The specific aims of the study are: Aim 1: To compare the cortical and subcortical grey matter synaptic density in progressive MS patients, patients with relapsing-remitting MS, and healthy subjects, using a novel [F-18] labeled synaptic density PET ligand, [F-18]SDM8, also known as [F-18]SynvesT-1. Aim 2: To compare the relationship of synaptic density PET and standard 3T MRI measures including global and regional brain atrophy and lesion load with clinical measures of physical disability, cognitive impairment, fatigue and depression in MS patients. Aim 3: To assess the relationship of synaptic density PET with serum neurofilament light chain (NfL) and with serum measurements of inflammatory markers, IL-1β, TNF-α, IL-6, MCP-1 (Monocyte Chemoattractant Protein-1) and MIF-1 (Macrophage Migration Inhibitory Factor-1).
Quantitative Analysis of Precise Brain Volume in Amyotrophic Lateral Sclerosis
Amyotrophic Lateral SclerosisUsing the original MRI images of 16 ALS patients and 16 normal controls matched by gender, age and education level in the previous study, the differences of brain volume in different parts of ALS patients and normal controls, and the correlation between brain structure and clinical characteristics were compared by precise brain volume quantitative analysis technology.
Multiple Sclerosis and Voiding Symptoms: How to Assess?
Multiple SclerosisLower Urinary Tract Symptoms1 moreIn multiple Sclerosis (MS), storage and voiding symptoms are well described. Urodynamic patterns underlying storage symptoms are clearly defined, but the assessment of voiding phase in neurological diseases is a sensitive topic. The international continence society (ICS) recommended performing pressure flow studies to assess voiding phase. Assessments of sphincter relaxation and detrusor contractility during voiding phase are tough aims to achieve. Indeed, there is no consensus for the detrusor contractility assessment on women or on patients with neurogenic bladder. Similarly, assessment of sphincter during bladder filling and during the voiding phase is not included in ICS recommendations. In the end, it is the physicians who conclude from the non-formalized urodynamic data if there is a DSD or detrusor underactivity. In MS patients undergoing urodynamics, studies reported 43% DSD and 12% impaired contractility. These data should be interpreted with caution due to the variability of the assessment methods. This study aims to describe the voiding phase of MS patients with standardized urodynamic evaluation and parameters. This prospective observational study was conducted in a neuro-urology department of a French university hospital. All the MS patients consulting for a first urodynamic evaluation without urinary treatment were included. Standardized urodynamic evaluation included an uroflowmetry, urethral pressure profile, two pressure-flow studies. If no detrusor contractility was observed during the pressure flow studies, cystometries with 100ml/min filling rate and ice water test were performed. Anal sphincter activity was recorded using surface electromyography electrodes. Demographic data (age, sex), disease course of the MS, treatments, Expanded Disability Status Scale, urinary symptoms using the Urinary Symptom Profile and the Neurogenic Bladder Symptom Score were collected. For assessment of detrusor contractility, the following parameters are reported: the bladder voiding efficiency; the projected isovolumetric pressure (PIP) or bladder contractility index (BCI); the Watts factor. For women, the investigators presented 3 more parameters the PIP1; the Valentini-besson-Nelson parameter k and an urodynamic cut-off proposed by Gammie et al. for DUA. Presence of Detrusor-sphincter dyssynergia was reported if there were a detrusor contraction concurrent with an involuntary contraction of the periurethral striated muscle.

Clinical Decision Support System (CADIMS) for MS Diagnostic
Multiple SclerosisRelapsing-RemittingBackground The results obtained in clinical research led to a new paradigm for the treatment of patients affected with multiple sclerosis (MS): "no evidence of disease activity". This means having each patient monitored with high quality imaging. To this purpose, researchers have developed segmentation algorithms for automated reading of MRIs, facilitating longitudinal comparisons, and allowing an accurate assessment of the number and the volume of focal lesions. We have thus a powerful strategic biomarker for the treatment of MS. Due to the relevance of comparing over time the evolution of lesions (lesion load) and brain atrophy, the French Society of Neuroradiology edited standardized national recommendations. The MS French Observatory (OFSEP) has adopted these recommendations, in order to harmonize exams for all patients all over the country. At an international level as well, MRI have been put at the heart of the therapeutic strategy. Therefore, we need now to create the conditions able to implement, collect and analyze imaging data according to these recommendations. This is the meaning of the MUSIC project, which aims to develop and assess a standardized monitoring MRI control tool for therapeutic decision. CADIMS is this tool. It is based on an integration of several segmentation algorithms developed by INRIA and an image viewer developed by b<>com and included in a regional images-sharing server ETIAM Nexus. This tool is a help showing segmented brain T2 lesions, gadolinium-enhanced T1 lesions and news T2 lesions appeared from the previous MRI exam, in a multicenter clinical context. Objective To evaluate the accuracy of MS lesions detection on cerebral MRI by comparing the CADIMS tool to the expert consensus.
