Background: Neocortical lesions (NLs) largely contribute to the pathology of multiple sclerosis (MS), although their relevance in patients’ disability remains unknown. Objective: To assess the incidence of T1 hypointense NLs by 3.0-Tesla magnetic resonance imaging (MRI) in patients with MS and examine neocortical lesion association with cognitive impairment. Methods: In this case-control study, 21 MS patients and 21 age-, sex- and years of education-matched healthy volunteers underwent: (i) a neuropsychological examination rating cognitive impairment (Minimal Assessment of Cognitive Function in MS); (ii) a 3.0-Tesla MRI inclusive of an isotropic 1.0 mm3 three-dimensional inversion prepared spoiled gradient-recalled-echo (3D-IRSPGR) image and T1- and T2-weighted images. Hypointensities on 3D-IRSPGR lying in the cortex, either entirely or partially were counted and association between NLs and cognitive impairment investigated. Results: A total of 95 NLs were observed in 14 (66.7%) patients. NL+ patients performed poorer (p = 0.020) than NLpatients only on the delayed recall component of the California Verbal Learning Test. This difference lost statistical significance when a correction for white matter lesion volume was employed. Conclusions: Although T 1 hypointense NLs may be present in a relatively high proportion of multiple sclerosis patients, the impact that they have in cognitive impairment is not independent from white matter disease.

An imbalance of TNF signalling in the inflammatory milieu generated by meningeal immune cell infiltrates in the subarachnoid space in multiple sclerosis (MS), and its animal model may lead to increased cortical pathology. In order to explore whether this feature may be present from the early stages of MS and may be associated with the clinical outcome, the protein levels of TNF, sTNF-R1 and sTNF-R2 were assayed in CSF collected from 122 treatment-naïve MS patients and 36 subjects with other neurological conditions at diagnosis. Potential correlations with other CSF cytokines/chemokines and with clinical and imaging parameters at diagnosis (T0) and after 2 years of follow-up (T24) were evaluated. Significantly increased levels of TNF (fold change: 7.739; p < 0.001), sTNF-R1 (fold change: 1.693; p < 0.001) and sTNF-R2 (fold change: 2.189; p < 0.001) were detected in CSF of MS patients compared to the control group at T0. Increased TNF levels in CSF were significantly (p < 0.01) associated with increased EDSS change (r = 0.43), relapses (r = 0.48) and the appearance of white matter lesions (r = 0.49). CSF levels of TNFR1 were associated with cortical lesion volume (r = 0.41) at T0, as well as with new cortical lesions (r = 0.56), whilst no correlation could be found between TNFR2 levels in CSF and clinical or MRI features. Combined correlation and pathway analysis (ingenuity) of the CSF protein pattern associated with TNF expression (encompassing elevated levels of BAFF, IFN-γ, IL-1β, IL-10, IL-8, IL-16, CCL21, haptoglobin and fibrinogen) showed a particular relationship to the interaction between innate and adaptive immune response. The CSF sTNF-R1-associated pattern (encompassing high levels of CXCL13, TWEAK, LIGHT, IL-35, osteopontin, pentraxin-3, sCD163 and chitinase-3-L1) was mainly related to altered T cell and B cell signalling. Finally, the CSF TNFR2-associated pattern (encompassing high CSF levels of IFN-β, IFN-λ2, sIL-6Rα) was linked to Th cell differentiation and regulatory cytokine signalling. In conclusion, dysregulation of TNF and TNF-R1/2 pathways associates with specific clinical/MRI profiles and can be identified at a very early stage in MS patients, at the time of diagnosis, contributing to the prediction of the disease outcome.

AbstractBackground:The pathophysiological basis for differences in disability in patients with multiple sclerosis is unclear.Methods:We used magnetic resonance imaging to examine whether differences in disability in cohorts of multiple sclerosis patients with similar T2-weighted lesion volume and disease duration were associated with a more destructive disease process in the more disabled patients.Results:The benign and severely disabled groups had similar brain atrophy metrics and similar decreases of the neuronal marker, N-acetylaspartate, in the normal appearing white matter of the cerebrum on magnetic resonance spectroscopy examination in vivo. The severely disabled cohort had more spinal cord atrophy.Conclusion:The dissociation of spinal cord atrophy and cerebral atrophy between these two groups suggests that the difference between the more benign and more disabled groups cannot be explained by a more aggressive pathological process that is affecting the entire neuroaxis in a homogeneous fashion.

Background: Cerebrospinal fluid tissue specific imaging (CSF-TSI), a newly implemented magnetic resonance imaging (MRI) technique, allows visualization of a subset of chronic black holes (cBHs) with MRI characteristics suggestive of the presence of CSF-like fluid, and representing lesions with extensive tissue destruction. Objective: To investigate the relationship between lesions in CSF-TSI and disease measures in patients with multiple sclerosis (MS). Methods: Twenty-six patients with MS were imaged at 3.0 T, obtaining T1-weighted (T1-w) and T2-w spin echo (SE), T1 volumetric images and CSF-TSI images. We measured: (i) lesion volume (LV) in T1-w (cBH-LV) and T2-w SE images, and in CSF-TSI; (ii) brain parenchyma fraction (BPF). Differences between patients with and without CSF-TSI lesions were analyzed and association between clinical and MRI metrics were investigated. Results: cBHs were seen in 92% of the patients while lesions in CSF-TSI were seen in 40%. Patients with CSF-TSI lesions were older, with longer disease duration, higher disability scores, larger cBH-LV and T2-LV, and lower BPF than patients without CSF-TSI lesions (≤0.047). Partial correlation analysis correcting for T2-LV, cBH-LV and BPF showed an association ( p < 0.0001, r = 0.753) between CSF-TSI LV and disability score. Conclusions: CSF-TSI lesions characterize patients with more advanced disease and probably contribute to the progress of disability.

We amplified sequences of the Chlamydia pneumoniae (C P) major-outer membrane protein in the cerebrospinal fluid (CSF) from 23 of 107 (21.5%) relapsing-remitting or secondary progressive multiple sclerosis (MS) patients and two of 77 (2.6%) patients with other neurological diseases (OND) (P =0.00022). C P+ patients showed magnetic resonance imaging (MRI) evidence of more active disease (P =0.02) compared to CP-MS patients and tended to have an anticipation of age at disease onset (32.39-12 versus 28.59-10 years; P =ns) causing a longer disease duration (7.59-5 versus 4.49-4 years; P =0.016) at the time of clinical evaluation. These findings, although indirectly, suggest that C P infection of the central nervous system (C NS) might affect disease course in a subgroup of MS patients.

Purpose: To investigate the MRI characteristics in a large cohort of multiple sclerosis (MS) patients with and without a family history of MS. Methods: Enrolled in this prospective study were 758 consecutive MS patients (mean age 46.2 ± 10.1 years, disease duration 13.6 ± 9.2 years and EDSS 3.4 ± 2.1), of whom 477 had relapsing–remitting, 222 secondary-progressive, and 30 primary-progressive disease courses and 29 had clinically isolated syndrome. One hundred and ninety-six patients (25.9%) had a positive family history of MS. Patients were assessed using measurements of lesions, brain atrophy, magnetization transfer ratio (MTR) and diffusion-weighted imaging. Results: The familial MS group had greater T1-lesion volume ( p=0.009) and a trend for lower MTR of T1-lesion volume ( p=0.047) than the sporadic MS group. No clinical differences were found between familial versus sporadic group, or by a degree of affected relative subgroups. Conclusions: While familial MS was associated with more severe T1-lesion volume and its MTR characteristics, there were no clinical status differences between familial and sporadic MS patients. Therefore, a better understanding of the genetic and/or epigenetic influences causing these differences can advance the understanding and management of MS.

Reduced muscle strength is one of the most important factors in violation of life in multiple sclerosis (MS). Muscle spasticity – another significant common symptom in patients with MS, which is one of the main reasons for the deepening of disability. The objective: to determine the prevalence of pyramidal disorders (PD), and sensory disorders (SD) in patients with MS and to find out the characteristics of their curs in the aspect of comorbidity. Patients and methods. Neurological examination 216 MS patients with different forms of process was held a points assessment of the disturbed functional systems of the FS11 – FS17 (scale FS1 Functional System for J. Kurtzke, 1983), determined the level of disability (the EDSS), revealed the presence or absence PD and SD in the survey, to determine the degree of severity and character. Results. At 88,4% PC patients had PD. Changes in muscle tone were found in 73.2% of patients with MS. In 65.3% of MS patients the total sample were clinical signs of superficial and deep sensitivity changes. In addition to medication for relief of PD and SD in patients with MS were effectively used methods of acupuncture, which allowed more quickly and efficiently to reduce the severity of spasticity and pain. Conclusions. 1. The average prevalence of PD in our study of MS patients is 88.4%, and the average prevalence of the SD – 65.3%. 2. In the group with the presence of comorbid pathology PD significantly more often manifested tetraparesis and high spastic tone. 3. In the group with the presence of comorbid pathology SD significantly more often manifested dysesthesia, termogiperestesia, palleanestesia.

AbstractThe pathophysiological mechanisms for classical plaque characteristics and their predictive value for clinical course and outcome in multiple sclerosis is unclear. Connectivity-based approaches incorporating the distribution and magnitude of the extended brain network aberrations caused by lesions may offer higher sensitivity for axonal damage. Using individual brain disconnectome mapping, we tested the longitudinal associations between putative brain network aberrations and levels of serum neurofilament light chain (sNfL) as a neuroaxonal injury biomarker.Multiple sclerosis patients (n = 328, mean age 42.9 years, 71 % female) were prospectively enrolled at four European multiple sclerosis centres, and reassessed after two years (n = 280). Post-processing of 3 Tesla (3T) MRI data was performed at one centre using a harmonized pipeline, and disconnectome maps were calculated using BCBtoolkit based on individual lesion maps. Global disconnectivity (GD) was defined as the average disconnectome probability in each patient’s white matter. Serum NfL concentrations were measured by single molecule array (Simoa). Robust linear mixed models (rLMM) with GD or T2-lesion volume (T2LV) as dependent variables, patient and centre as a random factor, sNfL, age, sex, timepoint for visit, diagnosis, and treatment as fixed factors were run.Robust LMM revealed significant associations between higher levels of GD and increased sNfL (t = 2.30, β = 0.03, p = 0.02), age (t = 5.01, β = 0.32, p < 5.5 × 10−7), and diagnosis progressive multiple sclerosis (PMS); t = 1.97, β = 1.06, p = 0.05), but not for sex (t = 0.78, p = 0.43), treatments (effective; t = 0.85, p = 0.39, highly-effective; t = 0.86, p = 0.39) or sNfL change between base line and two-year follow up (t = −1.65, p = 0.10). Voxel-wise analyses revealed distributed associations in cerebellar and brainstem regions.In our prospective multi-site multiple sclerosis cohort, rLMMs demonstrated that the extent of global brain disconnectivity is sensitive to a systemic biomarker of axonal damage, sNfL, in patients with multiple sclerosis. These findings provide a neuropathological correlate of advanced disconnectome mapping and provide a platform for further investigations of the functional and clinical relevance in patients with brain disorders.
