The association between cognitive impairment, health-related quality of life (HRQoL) and vocational status has been studied in recent years in cross-sectional studies in multiple sclerosis (MS), but ...longitudinal data are still lacking. This study assesses this association in a sample of 65 newly diagnosed MS patients followed longitudinally. Each patient underwent a standardised clinical assessment, cognitive tests and the HRQoL SEP-59 questionnaire six months after the MS diagnosis (baseline) and seven years later (y7).Vocational status was also established at baseline and at y7 in MS patients. The HRQoL at baseline was severely reduced in MS patients compared with healthy subjects. The independent predictors for HRQoL composite scores at y7 were the baseline depression score and the memory
Z
-score. Accordingly, 81.5 % of MS patients worked at baseline and only 54.4 % worked at y7. Among the MS patients who did not work at y7, 72.7 % of them were cognitively impaired, while 27.3 % were unimpaired at baseline. The vocational status at y7 was significantly associated with the baseline IPS
Z
-score, EDSS and age. Vocational status at y7 and its change over 7 years was significantly associated with cognitive deterioration. IPS or memory dysfunction in the early stages of MS is correlated with a decreased level in health perception, independent of fatigue, depression and physical disability. Cognitive impairment at the diagnosis of MS increases the risk of changing vocational status in MS patients seven years later.
Introduction
No randomized controlled clinical trial of therapeutic plasma exchanges (TPE) has yet been performed for moderate‐to‐severe relapses of multiple sclerosis (MS).
Objective
To compare TPE ...to sham‐TPE in patients with a recent steroid‐resistant moderate‐to‐severe MS relapse.
Methods
Patients presenting with an MS relapse of less than 2 months without improvement and 15 days after a course of steroids were randomized. Specific criteria were used for each relapse type to define moderate‐to‐severe disability. The primary endpoint was the proportion of patients with at least a moderate improvement based on objective and functional evaluation after 1 month.
Results
Thirty‐eight patients were randomized. The intention‐to‐treat analysis included 14 patients in the TPE group and 17 in the Sham‐TPE group. The proportion of patients with at least moderate improvement at 1 month did not differ between the groups (P = .72), although 57.1% of the TPE group had full recovery compared with 17.6% of the sham group. Considering optic neuritis (ON), a significant difference in the proportion of different levels of improvement was observed in favor of the TPE group (P = .04). The combined Kurtzke's functional systems scores were significantly more improved in the TPE group than in the sham‐TPE group at months 1 (P < .01), 3 (P < .05), and 6 (P < .05). No major side effects were observed.
Conclusions
A significant difference between TPE and Sham‐TPE at the primary endpoint was only observed in patients with ON. Neurological function improved significantly more often in the TPE group than in the sham‐TPE group.
Therapeutic options are limited in secondary progressive multiple sclerosis (SPMS). Open-label studies suggested efficacy of monthly IV cyclophosphamide (CPM) without induction for delaying ...progression but no randomized trial was conducted so far.
To compare CPM to methylprednisolone (MP) in SPMS.
Randomized, double-blind clinical trial on two parallel groups. Patient with SPMS, with a documented worsening of the Expanded Disability Status Scale (EDSS) score during the last year and an EDSS score between 4·0 and 6·5 were recruited and received one intravenous infusion of treatment (CPM: 750 mg /m2 body surface area-MP: 1g) every four weeks for one year, and every eight weeks for the second year. The primary endpoint was the time to EDSS deterioration, when confirmed sixteen weeks later, analyzed using a Cox model.
Due to recruitment difficulties, the study was terminated prematurely after 138 patients were included (CPM, n = 72; MP, n = 66). In the CPM group, 33 patients stopped treatment prematurely, mainly due to tolerability, compared with 22 in the MP group. Primary endpoint: the hazard ratio for EDSS deterioration in the CPM in comparison with the MP group was 0.61 95% CI: 0·31-1·22(p = 0·16). According to the secondary multistate model analysis, patients in the CPM group were 2.2 times more likely (1·14-4.29; p = 0.02) to discontinue treatment than those in the MP group and 2.7 times less likely (HR = 0.37, 95% CI: 0.17-0.84; p = 0.02) to experience disability progression when they did not stop treatment prematurely. Safety profile was as expected.
Although the primary end-point was negative, secondary analysis suggested that CPM decreases the risk of progression in SPMS, but its use may be limited by low tolerability.

Depressive mood and other emotional symptoms are common in multiple sclerosis (MS). The patient-reported outcome version of the "Echelle d'Humeur Dépressive" (EHD-PRO) aims to differentiate between ...two dimensions of depressive mood in people living with MS (PwMS).
First, to compare EHD-PRO assessment and its two dimensions, lack of emotional control and emotional blunting, between a large sample of healthy controls (HCs) and two samples of PwMS, relapsing-remitting MS (RRMS) and primary progressive MS (PPMS); and second, to analyse the relationships between EHD-PRO scores with neurological disability, cognitive function, fatigue and health-related quality of life (HR-QOL).
Regardless of their phenotype, PwMS had significantly higher EHD-PRO scores than HCs. EHD-PRO scores did not differ between the two MS groups. EHD-PRO scores did not correlate with disability and fatigue scores, disease duration or cognitive z scores. In RRMS, the lack of emotional control was independently associated with a decrease in HR-QOL.
The EHD-PRO is able to easily detect depressive mood and to differentiate between two clinical dimensions, emotional blunting and lack of emotional control. The scale is sensitive and seems robust to confounding factors. Lack of emotional control seems to contribute significantly to altered HR-QOL in RRMS.

Preliminary observations of humoral immunity against the myelin oligodendrocyte glycoprotein (MOG) in experimental allergic encephalomyelitis (EAE) and human multiple sclerosis (MS) suggest that a ...subset of anti‐MOG autoantibodies directed against conformational epitopes is of pathogenic predominance. Here, we provide proof that in marmoset EAE, autoantibodies reactive against conformational epitopes of MOG are not only responsible for aggravating demyelination, but also an essential factor for disease dissemination in space within the central nervous system, a hallmark for typicalforms of human MS. In terms of effector mechanisms, IgG deposition and complement activation occur exclusively in association with presence of these conformational antibodies, while microglial/macrophage activation appears to be a common immunopathological finding regardless of the fine determinant specificity of anti‐MOG antibodies. These findings highlight for the first time the complex heterogeneity of function and pathogenicity in the polyclonal anti‐MOG antibody repertoire of outbred species. Because the linear and conformational antibody determinants of MOG are shared between marmosets and humans, these results are directly relevant to understanding effector mechanisms of organ damage in MS.

Cerebellar damage has been implicated in information processing speed (IPS) impairment associated with multiple sclerosis (MS) that might result from functional disconnection in the frontocerebellar ...loop. Structural alterations in individual posterior lobules, in which cognitive functioning seems preponderant, are still unknown. Our aim was to investigate the impact of grey matter (GM) volume alterations in lobules VI to VIIIb on IPS in persons with clinically isolated syndrome (PwCIS), MS (PwMS) and healthy subjects (HS).
69 patients (37 PwCIS, 32 PwMS) and 36 HS underwent 3 T MRI including 3-dimensional T1-weighted MRIs. Cerebellum lobules were segmented using SUIT V.3.0 to estimate their normalised GM volume. Neuropsychological testing was performed to assess IPS and main cognitive functions.
Normalised GM volumes were significantly different between PwMS and HS for the right (p<0.001) and left lobule VI (p<0.01), left crus I, right VIIb and entire cerebellum (p<0.05 for each comparison) and between PwMS and PwCIS for all lobules in subregions VI and left crus I (p<0.05). IPS, attention and working memory were impaired in PwMS compared with PwCIS. In the whole population of patients (PwMS and PwCIS), GM loss in vermis VI (R
=0.36; p<0.05 when considering age and T2 lesion volume as covariates) were associated with IPS impairment.
GM volume decrease in posterior lobules (especially vermis VI) was associated with reduced IPS. Our results suggest a significant impact of posterior lobules pathology in corticocerebellar loop disruption resulting in automation and cognitive optimisation lack in MS.

Neuromyelitis optica (NMO) is a life-threatening disease without any validated treatment strategy. Recent retrospective studies suggested the efficacy of B cell depletion without any distinction ...between first-line or rescue therapy. To assess whether rituximab as first-line therapy in NMO could efficiently control the occurrence of relapses. A retrospective analysis of NMO patients from NOMADMUS network found 32 patients receiving rituximab as first-line therapy. Main measures were number of relapse-free patients, changes in the annualized relapse rate (ARR), and changes in the EDSS. Tolerance was reported. At baseline, NMO patients were 45 ± 12.1 years old, with a sex ratio of 5.4, and 87.5 % of them had AQP4 antibodies. The median disease duration was 6.5 months (1–410), the mean EDSS was 5.8 ± 2.4 and the mean ARR was 3.8 ± 4.3. After rituximab with a mean follow-up of 28.7 ± 21 months, twenty-seven patients (84.3 %) were relapse free. Patients presented a 97 % decrease of ARR (
p
= 0.00001). EDSS decreased significantly to 3.9 ± 2.6 (
p
= 0.01). No relevant side effect was noted. New retrospective data are presented on RTX use in NMOSD. When used as first-line therapy RTX is highly effective and well tolerated.
Exogenous sexual steroids together with pregnancy have been shown to influence the risk of relapses in multiple sclerosis (MS). Treatments used during assisted reproductive techniques may ...consequently influence the short term evolution of MS by modifying the hormonal status of the patient. The objective of this study was to determine if there was an increased risk of developing exacerbations in women with MS after in vitro fertilisation (IVF).
MS and IVF data were either automatically extracted from 13 French university hospital databases or obtained from referring neurologists. After matching databases, patient clinical files were systematically reviewed to collect information about MS and the treatments used for IVF. The association between IVF and the occurrence of MS relapses was analysed in detail using univariate and multivariate statistical tests.
During the 11 year study period, 32 women with MS had undergone 70 IVF treatments, 48 using gonadotrophin releasing hormone (GnRH) agonists and 19 using GnRH antagonists. A significant increase in the annualised relapse rate (ARR) was observed during the 3 month period following IVF (mean ARR 1.60, median ARR 0) compared with the same period just before IVF (mean ARR 0.80, median ARR 0) and to a control period 1 year before IVF (mean ARR 0.68, median ARR 0). The significant increase in relapses was associated with the use of GnRH agonists (Wilcoxon paired test, p=0.025) as well as IVF failure (Wilcoxon paired test, p=0.019).
An increased relapse rate was observed in this study after IVF in patients with MS and may be partly related both to IVF failure and the use of GnRH agonists.
Domains encompassing emotional disorders in relapsing-remitting MS (RRMS) patients are still unclear.
We performed a 24-month, multicenter, single-arm, prospective study. RRMS patients started IFN-β ...treatment at baseline. The primary endpoint was lack of emotional control, measured using the “Echelle d'HumeurDépressive” (EHD) scale three times at baseline and at 10 post-treatment visits. Secondary endpoints were emotional blunting, irritability, fatigue, depression and anxiety. A linear mixed covariance model assessed change from baseline on an intention-to-treat basis, under the assumption of no mood disorder effect (one-sided 97.5% level), in which autoregressive type of autocorrelation was tested.
Out of 79 recruited patients, 70 were analyzed: 80% female; mean (SD) age, 37.0 (11.5) years. Mean (SD) lack of emotional control score at baseline and Month 24 was 12.7 (4.4) and 12.6 (5.5), respectively, versus 10.1 (3.2) in a healthy control population matched for age and sex. Stepwise analysis identified younger age, male sex and antidepressant use as significant predictors of higher lack of emotional control values.
Based on 24 months of prospective follow-up, the results of this study highlights a broad spectrum of emotional disorders in the MS population at the time of disease modifying drugs initiation but no major IFN-β-related emotional disorders (mood dyscontrol, anxiety, depression) were observed. However, sporadic occurrences of severe mood disorders and suicidality cannot be excluded.
