Abstract

Objective:To assess whether chronic white matter inflammation in patients with multiple sclerosis (MS) as detected in vivo by paramagnetic rim MRI lesions (PRLs) is associated with higher serum neurofilament light chain (sNfL) levels, a marker of neuroaxonal damage. Methods:In 118 patients with MS with no gadolinium-enhancing lesions or recent relapses, we analyzed 3D-submillimeter phase MRI and sNfL levels. Histopathologic evaluation was performed in 25 MS lesions from 20 additional autopsy MS cases. Results:In univariable analyses, participants with ≥2 PRLs (n = 43) compared to those with ≤1 PRL (n = 75) had higher age-adjusted sNfL percentiles (median, 91 and 68;p< 0.001) and higher Multiple Sclerosis Severity Scale scores (MSSS median, 4.3 and 2.4;p= 0.003). In multivariable analyses, sNfL percentile levels were higher in PRLs ≥2 cases (βadd, 16.3; 95% confidence interval [CI], 4.6-28.0;p< 0.01), whereas disease-modifying treatment (DMT), Expanded Disability Status Scale (EDSS) score, and T2 lesion load did not affect sNfL. In a similar model, sNfL percentile levels were highest in cases with ≥4 PRLs (n = 30; βadd, 30.4; 95% CI, 15.6-45.2;p< 0.01). Subsequent multivariable analysis revealed that PRLs ≥2 cases also had higher MSSS (βadd, 1.1; 95% CI, 0.3-1.9;p< 0.01), whereas MSSS was not affected by DMT or T2 lesion load. On histopathology, both chronic active and smoldering lesions exhibited more severe acute axonal damage at the lesion edge than in the lesion center (edge vs center:p= 0.004 andp= 0.0002, respectively). Conclusion:Chronic white matter inflammation was associated with increased levels of sNfL and disease severity in nonacute MS, suggesting that PRL contribute to clinically relevant, inflammation-driven neurodegeneration.

Abstract

Objective: To evaluate the safety, tolerability, and efficacy of glatiramer acetate (GA) 40mg compared to a 20mg dose. Methods: Patients with multiple sclerosis (MS) with ≥1 documented relapse in 12 months prior to screening, or ≥2 documented relapses in 24 months prior to screening, and Expanded Disability Status Scale (EDSS) score 0 to 5.5 were enrolled. Patients were evaluated at screening, baseline, and at months 1, 2, 3, 6, 9, and 12. Primary endpoint was rate of confirmed relapses observed during 12-month study. Analysis was by intent-to-treat. Results: A total of 1,155 patients randomized to GA 20mg (n = 586) or 40mg (n = 569). The groups were well-matched at baseline on demographic, clinical, and magnetic resonance imaging (MRI) characteristics. The primary endpoint was similar in both groups (relative risk [RR] = 1.07; 95% confidence interval [CI], 0.88–1.31; p = 0.486) with mean annualized relapse rates (ARRs) of 0.33 for the 20mg group, 0.35 for the 40mg group, and 0.27 for patients from both groups who completed the entire 1-year treatment. A total of 77% of patients remained relapse-free in both groups. Both groups showed a reduction in mean number of gadolinium-enhancing and new T2 lesions over time with trend for faster reduction in the first trimester with the 40mg dose compared with 20mg dose. Both doses were well-tolerated with a safety profile similar to that observed in previous studies of 20mg GA. Interpretation: In relapsing-remitting MS patients, both the currently-approved GA 20mg and 40mg doses were safe and well-tolerated, with no gain in efficacy for the higher dose.

Abstract

To assess in a large population of patients with clinically isolated syndrome (CIS) the relevance of brain lesion location and frequency in predicting 1-year conversion to multiple sclerosis (MS).In this multicenter, retrospective study, clinical and MRI data at onset and clinical follow-up at 1 year were collected for 1,165 patients with CIS. On T2-weighted MRI, we generated lesion probability maps of white matter (WM) lesion location and frequency. Voxelwise analyses were performed with a nonparametric permutation-based approach (p0.05, cluster-corrected).In CIS patients with hemispheric, multifocal, and brainstem/cerebellar onset, lesion probability map clusters were seen in clinically eloquent brain regions. Significant lesion clusters were not found in CIS patients with optic nerve and spinal cord onset. At 1 year, clinically definite MS developed in 26% of patients. The converting group, despite a greater baseline lesion load compared with the nonconverting group (7 ± 8.1 cm3 vs. 4.6 ± 6.7 cm3, p0.001), showed less widespread lesion distribution (18% vs. 25% of brain voxels occupied by lesions). High lesion frequency was found in the converting group in projection, association, and commissural WM tracts, with larger clusters being in the corpus callosum, corona radiata, and cingulum.Higher frequency of lesion occurrence in clinically eloquent WM tracts can characterize CIS subjects with different types of onset. The involvement of specific WM tracts, in particular those traversed by fibers involved in motor function and near the corpus callosum, seems to be associated with a higher risk of clinical conversion to MS in the short term.

Abstract

""In this multicentre study involving eight European centres, we characterized the spatial pattern of functional connectivity (FC) in the sensorimotor network from 61 right-handed patients with multiple sclerosis (MS) and 74 age-matched healthy subjects assessed with the use of functional magnetic resonance imaging (fMRI) and a simple motor task of their right dominant hand. FC was investigated by using: (i) voxel-wise correlations between the left sensorimotor cortex (SMC) and any other area in the brain; and (ii) bivariate correlations between time series extracted from several regions of interest (ROIs) belonging to the sensorimotor network. Both healthy controls and MS patients had significant FC between the left SMC and several areas of the sensorimotor network, including the bilateral postcentral and precentral gyri, supplementary motor area, middle frontal gyri, insulae, secondary somatosensory cortices, thalami, and right cerebellum. Voxel-wise assessment of FC revealed increased connectivity between the left SMC and the right precentral gyrus, right middle frontal gyrus (MFG) and bilateral postcentral gyri in MS patients as compared with controls. ROI analysis also showed a widespread pattern of altered connectivity, characterized by increased FC between the right MFG, the left insula and the right inferior frontal gyrus in comparison with many regions of the sensorimotor network. These results provide further evidence for increased bihemispheric contributions to motor control in patients with MS relative to healthy controls. They further suggest that multicentre fMRI studies of FC changes are possible, and provide a potential imaging biomarker for use in experimental therapeutic studies directed at enhancing adaptive plasticity in the disease.""
