Abstract: Background: Dopamine responsiveness (dopa-sensitivity) is an important parameter in the management of patients with Parkinson’s disease (PD). For quantification of this parameter, patients undergo a challenge test with acute Levodopa administration after drug withdrawal, which may lead to patient discomfort and use of significant resources. Objective: Our objective was to develop a predictive model combining clinical scores and imaging. Methods: 350 patients, recruited by 13 specialist French centers and considered for deep brain stimulation, underwent an acute L-dopa challenge (dopa-sensitivity > 30%), full assessment, and MRI investigations, including T1w and R2* images. Data were randomly divided into a learning base from 10 centers and data from the remaining centers for testing. A machine selection approach was applied to choose the optimal variables and these were then used in regression modeling. Complexity of the modelling was incremental, while the first model considered only clinical variables, the subsequent included imaging features. The performances were evaluated by comparing the estimated values and actual values Results: Whatever the model, the variables age, sex, disease duration, and motor scores were selected as contributors. The first model used them and the coefficients of determination (R2) was 0.60 for the testing set and 0.69 in the learning set (p

Abstract: International audience; Background: Parkinson’s disease mild cognitive impairment (PD-MCI) is frequent and heterogenous. There is no consensus about its influence on subthalamic deep brain stimulation (STN-DBS) outcomes. Objective: To determine the prevalence of PD-MCI and its subtypes in candidates to STN-DBS. Secondarily, we sought to identify MRI structural markers associated with cognitive impairment in these subgroups. Methods: Baseline data from the French multicentric PREDISTIM cohort were used. Candidates to STN-DBS were classified according to their cognitive performance in normal cognition (PD-NC) or PD-MCI. The latter included frontostriatal (PD-FS) and posterior cortical (PD-PC) subtypes. Between-group comparisons were performed on demographical and clinical variables as well as on T1-weighted MRI sequences at the cortical and subcortical levels. Results: 320 patients were included: 167 (52%) PD-NC and 153 (48%) PD-MCI patients. The latter group included 123 (80%) PD-FS and 30 (20%) PD-PC patients. There was no between-group difference regarding demographic and clinical variables. PD-PC patients had significantly lower global efficiency than PD-FS patients and significantly worse performance on visuospatial functions, episodic memory, and language. Compared to PD-NC, PD-MCI patients had cortical thinning and radiomic-based changes in the left caudate nucleus and hippocampus. There were no significant differences between the PD-MCI subtypes. Conclusion: Among the candidates to STN-DBS, a significant proportion has PD-MCI which is associated with cortical and subcortical alterations. Some PD-MCI patients have posterior cortical deficits, a subtype known to be at higher risk of dementia.

Abstract: Background and ObjectivesKappa free light chains (KFLC) seem to efficiently diagnose MS. However, extensive cohort studies are lacking to establish consensus cut-offs, notably to rule out non-MS autoimmune CNS disorders. Our objectives were to (1) determine diagnostic performances of CSF KFLC, KFLC index, and KFLC intrathecal fraction (IF) threshold values that allow us to separate MS from different CNS disorder control populations and compare them with oligoclonal bands' (OCB) performances and (2) to identify independent factors associated with KFLC quantification in MS.MethodsWe conducted a retrospective multicenter study involving 13 French MS centers. Patients were included if they had a noninfectious and nontumoral CNS disorder, eligible data concerning CSF and serum KFLC, albumin, and OCB. Patients were classified into 4 groups according to their diagnosis: MS, clinically isolated syndrome (CIS), other inflammatory CNS disorders (OIND), and noninflammatory CNS disorder controls (NINDC).ResultsOne thousand six hundred twenty-one patients were analyzed (675 MS, 90 CIS, 297 OIND, and 559 NINDC). KFLC index and KFLC IF had similar performances in diagnosing MS from nonselected controls and OIND (p= 0.123 andp= 0.991 for area under the curve [AUC] comparisons) and performed better than CSF KFLC (p< 0.001 for all AUC comparisons). A KFLC index of 8.92 best separated MS/CIS from the entire nonselected control population, with better performances than OCB (p< 0.001 for AUC comparison). A KFLC index of 11.56 best separated MS from OIND, with similar performances than OCB (p= 0.065). In the multivariate analysis model, female gender (p= 0.003), young age (p= 0.013), and evidence of disease activity (p< 0.001) were independent factors associated with high KFLC index values in patients with MS, whereas MS phenotype, immune-modifying treatment use at sampling, and the FLC analyzer type did not influence KFLC index.DiscussionKFLC biomarkers are efficient tools to separate patients with MS from controls, even when compared with other patients with CNS autoimmune disorder. Given these results, we suggest using KFLC index or KFLC IF as a criterion to diagnose MS.Classification of EvidenceThis study provides Class III evidence that KFLC index or IF can be used to differentiate patients with MS from nonselected controls and from patients with other autoimmune CNS disorders.

Abstract: In France, two therapeutic strategies can be offered after fingolimod (FNG) withdrawal to highly active relapsing–remitting multiple sclerosis (RRMS) patients: natalizumab (NTZ) or anti-CD20. We compared the effectiveness of these two strategies as a switch for FNG within the OFSEP database. The primary endpoint was the time to first relapse. Other outcomes were the relapse rates over 3-month periods, time to worsening the EDSS score, proportion of patients with worsened 24-month MRI, time to treatment discontinuation, and incidence rates of serious adverse events. The dynamics of event rates over time were modeled using multidimensional penalized splines, allowing the possibility to model the effects of covariates in a flexible way, considering non-linearity and interactions. A total of 740 patients were included (337 under anti-CD20 and 403 under NTZ). There was no difference between the two treatments regarding the dynamic of the first occurrence of relapse, with a monthly probability of 5.0% at initiation and 1.0% after 6 months. The rate of EDSS worsening increased in both groups until 6 months and then decreased. No difference in the proportion of patients with new T2 lesions at 24 months was observed. After 18 months of follow-up, a greater risk of NTZ discontinuation was found compared to anti-CD20. This study showed no difference between NTZ and anti-CD20 after the FNG switch regarding the clinical and radiological activity. The effect of these treatments was optimal after 6 months and there was more frequent discontinuation of NTZ after 18 months, probably mainly related to JC virus seroconversions.

Abstract: Introduction: Recent studies suggested that anti-CD20 and fingolimod may be associated with lower anti-spike protein-based immunoglobulin-G response following COVID-19 vaccination. We evaluated if COVID-19 occurred despite vaccination among patients with multiple sclerosis (MS) and neuromyelitis optica (NMO), using the COVISEP registry. Case series: We report 18 cases of COVID-19 after two doses of BNT162b2-vaccination, 13 of which treated with anti-CD20 and four with fingolimod. COVID-19 severity was mild. Discussion: These results reinforce the recommendation for a third COVID-19 vaccine dose among anti-CD20 treated patients and stress the need for a prospective clinical and biological study on COVID-19 vaccine efficacy among MS and NMO patients.

Abstract: International audience; Functional Magnetic Resonance Imaging (fMRI) has been so far the golden standard to study the functional aspects of the cerebellum. In this paper, a low-cost alternative imaging, i.e. functional Near-Infrared Spectroscopy (fNIRS) is demonstrated to achieve successful measurements of the cerebellar hemodynamics towards the challenging observation of motor and cognitive processes at the cerebellar level. The excitation and reception optodes need to be properly placed to circumvent a major hindering from the shielding by the neck muscles. A simple experimental protocol, i.e. finger tapping task, was implemented to observe the subject’s engagement and the presence of functional asymmetries. Marked differences among subjects with different levels of lateralization were clearly noticed in terms of activation and latencies, together with peaks in the hemodynamic response following neural activation. These preliminary results suggest also differences in the hemodynamic behavior between the brain and the cerebellum and encourage future and extended analysis in this direction.Clinical Relevance—This establishes the possibility to use a novel technique (fNIRS) to study cerebellar hemodynamics instead of fMRI.

Abstract: International audience; The estimation of Event-Related Potentials (ERPs) from the ambient EEG is a difficult task, usually achieved through the synchronous averaging of an extensive series of trials. However, this technique has some caveats: the ERPs have to be strictly time-locked with similar shape, i.e. emitted with the same latency and the same profile, with minor fluctuations of their amplitudes. Also, the method requires a huge number of valid trials (~100) to efficiently raise the ERPs from the EEG trials. In the case of cognitive ERPs, as with the N400, the delivered stimulus has to be different for each trial, the latencies are varying, and the number of available trials is usually low. In this paper, an alternative method, coined Integral Shape Averaging (ISA) and its derivatives are detailed. ISA is robust to varying latencies and affine transforms of shape. Furthermore, a new method coined ISAD can be derived to extract ERPs even from a single trial experiment. The aim here is to illustrate the potential of ISAD for N400 component extraction on real EEG data, with emphasis on its general applicability for ERPs computation and its major assets like reduced experimental protocol. Some insights are also given on its potential use to study ERP variability, through shape and latency.Clinical Relevance— The proposed algorithm aims to be a helpful tool in clinical practice to analyze and interpret evoked responses in real experimental settings, especially for particularities in neurology.

Abstract: Objectives: We aim to (1) determine the frequency and distinctive features of short myelitis (SM) and longitudinally extensive transverse myelitis (LETM) in a cohort of adults with myelin oligodendrocyte glycoprotein (MOG)-antibody (Ab)-associated myelitis and (2) determine baseline prognostic factors among MOG-Ab-positive patients whose disease started with myelitis. Material and Methods: We retrospectively analyzed clinical and paraclinical variables from a multicentric French cohort of adults with MOG-Ab-associated myelitis. At last follow-up, patients were classified into two groups according to the severity of the Expanded Disability Status Scale (EDSS) as ⩽2.5 or ⩾3.0. Results: Seventy-three patients with at least one episode of myelitis over disease course were included; among them, 28 (38.4%) presented with SM at the time of the first myelitis. Motor and sphincter involvement was less frequently observed in SM (51.9% and 48.2%, respectively) than in LETM patients (83.3% and 78.6%, respectively), p = 0.007 and p = 0.017; 61% of LETM patients displayed brain lesions compared to 28.6% in the SM group, p = 0.008, and the thoracic segment was more frequently involved in the LETM (82.2%) than in the SM group (39.3%), p Conclusion: SM in MOG-Ab-associated disease is not rare. The severity at onset was the only independent factor related to the final prognosis in MOG-Ab-associated myelitis.

Abstract: International audience; Background and purposeTo determine the precise incidence of lesions at sites of high Aquaporin-4 expression (hAQP4) and their possible association with known neuromyelitis optica spectrum disease (NMOSD) lesions patterns.Materials and methodsA retrospective analysis of brain and, when available, spinal cord MRI scans of 54 NMOSD patients recruited among the French NMOSD cohort was performed. Brain lesions were annotated as MS-like, non-specific, or evocative of NMOSD. The topography of hAQP4 was reassessed by human brain atlas. The incidence of lesions in hAQP4 and their association with lesions evocative of NMOSD was estimated.ResultsAmong those included (41/54 female, mean age: 45 years) 47/54 (87%) presented brain lesions. Twenty-six/47 (55%) had lesions in hAQP4. Thirty-two/54 patients (60%) had lesions considered evocative of NMOSD. The majority of them also presented lesions in hAQP4 (65%, 21/32). Patients with lesions in hAQP4 and lesions evocative of NMOSD demonstrated more extensive myelitis compared to the other patients (7 [6–10] versus 4 [3–5] vertebral segments, P = 0.009).ConclusionThe coexistence of lesions evocative of NMOSD and in hAQP4 is associated with significantly more extensive myelitis, and might have pathophysiological and clinical significance.

Abstract: Background and ObjectivesTo determine whether patients with Parkinson disease (PD) eligible for subthalamic nucleus deep brain stimulation (STN-DBS) with probable REM sleep behavior disorder (RBD) preoperatively could be more at risk of poorer motor, nonmotor, and quality of life outcomes 12 months after surgery compared to those without RBD.MethodsWe analyzed the preoperative clinical profile of 448 patients with PD from a French multicentric prospective study (PREDISTIM) according to the presence or absence of probable RBD based on the RBD Single Question and RBD Screening Questionnaire. Among the 215 patients with PD with 12 months of follow-up after STN-DBS, we compared motor, cognitive, psycho-behavioral profile, and quality of life outcomes in patients with (pre-opRBD+) or without (pre-opRBD–) probable RBD preoperatively.ResultsAt preoperative evaluation, pre-opRBD+ patients were older (61 ± 7.2 vs 59.5 ± 7.7 years; p = 0.02), had less motor impairment (Movement Disorder Society–sponsored version of the Unified Parkinson’s Disease Rating Scale [MDS-UPDRS] III “off”: 38.7 ± 16.2 vs 43.4 ± 7.1; p = 0.03) but more nonmotor symptoms on daily living activities (MDS-UPDRS I: 12.6 ± 5.5 vs 10.7 ± 5.3; p < 0.001), had more psychobehavioral manifestations (Ardouin Scale of Behavior in Parkinson's Disease total: 7.7 ± 5.1 vs 5.1 ± 0.4; p = 0.003), and had worse quality of life (Parkinson's Disease Questionnaire–39: 33 ± 12 vs 29 ± 12; p = 0.03), as compared to pre-opRBD– patients. Both pre-opRBD+ and pre-opRBD– patients had significant MDS-UPDRS IV score decrease (−37% and −33%, respectively), MDS-UPDRS III “med ‘off’/stim ‘on’” score decrease (−52% and −54%), and dopaminergic treatment decrease (−52% and −49%) after surgery, with no between-group difference. There was no between-group difference for cognitive and global quality of life outcomes.ConclusionsIn patients with PD eligible for STN-DBS, the presence of probable RBD preoperatively is not associated with a different clinical outcome 1 year after neurosurgery.Trial Registration InformationNCT02360683.Classification of EvidenceThis study provides Class II evidence that in patients with PD eligible for STN-DBS, the presence of probable RBD preoperatively is not associated with poorer outcomes 1 year post surgery.

Abstract: International audience; * Introduction: Research about cerebellar functions has become a trendy field of study, especially regarding the cerebellum involvement in sensorimotor control. The heterogeneity of the findings encourages further investigations in cerebellar activation, hemisphere specificity, but also calls for new techniques to allow easier, cheaper routine assessments. In this study, we investigated hemispheric cerebellar activation during finger movements of the dominant and subdominant hand using functional near-infrared spectroscopy (fNIRS).* Methods: One healthy right-handed subject performed a finger-tapping task consisting of six repetitive blocks (task + rest), respectively, for the left and right hands. The task was repeated twice for each hand changing the activity periods: first, 10 seconds of tapping followed by 30 seconds of rest; then, 20 seconds of tapping followed by 30 seconds of rest. Cerebellar responses for each repetition were time-locked averaged.* Results: Similar haemodynamic responses were observed ipsilaterally and contralaterally for both tasks (10 vs 20 seconds activity). The dominant hemisphere (right-handed subject) proved to be involved even during subdominant hand movements. Higher synchronization of the right hemisphere for left-hand movement was observed and validated using frequency domain analysis.* Conclusion: fNIRS proved to be a good technique to capture cerebellar haemodynamics in a non-clinical setting. Furthermore, the observed asymmetries in cerebellar activation fully agree with similar fMRI studies that suggest the existence of different layers of controls from the cerebellum in the two hemispheres.

Abstract: International audience; Background: There are few head-to-head studies to compare highly active treatments in multiple sclerosis (MS) Objective: The aim of this study was to compare the effectiveness between natalizumab (NTZ) and fingolimod (FTY) in active relapsing–remitting MS Method: Best Escalation STrategy in Multiple Sclerosis (BEST-MS) is a multicentric, prospective study with a 12-month follow-up including patients with active MS. Treatment choice was at the discretion of physician. Clinical and magnetic resonance imaging (MRI) data were collected at baseline and at 12 months. The primary outcome was the proportion of patients reaching no evidence of disease activity (NEDA) at 12 months. Secondary outcomes included annualized relapse rate and MRI activity. Results: A total of 223 patients were included (NTZ: 109 and FTY: 114). Treatment groups were well balanced at baseline. Proportion of NEDA patients was 47.8% in NTZ group versus 30.4% in FTY group ( p = 0.015). This superiority was driven by annualized relapse rate and MRI activity. In the multivariate analysis, treatment group was the only factor associated with NEDA at 12 months with a lower probability in FTY group (odds ratio (OR) = 0.49, p = 0.029). Conclusion: BEST-MS is a prospective study that compared head-to-head the effectiveness of NTZ and FTY in active relapsing–remitting MS. Our results suggest a superiority of NTZ over FTY.

Abstract: International audience; Aim/Introduction: The design and validation of a reliable radiomic signature is challenging when few patients are available because the disease is rare, the imaging protocol is specific and/or the classes are unbalanced. In this context, we propose an approach to identify a signature and estimate its reliability. Materials and Methods: 84 patients with a clinical and MRI suspicion of recurrent glioblastoma were retrospectively included. Each patient underwent a 18F-FDOPA PET-CT scan. For each patient, the suspicious lesion was segmented and 49 radiomic features were calculated using LIFEx [1]. Our goal was to distinguish between tumor recurrence and radiation-induced necrosis as confirmed on pathological data, or on a 3-month clinical/imaging follow-up. A screening procedure was developed to identify a signature using leave-one-out (LOO) cross-validation. The procedure involved: 1) selection of all features with a p-value of univariate Wilcoxon test lower than alpha varying from 0.005 to 0.10 for (N-1) learning patients, 2) based on these features, selection of only one feature among correlated features using a Pearson correlation cutoff R varying from 0.95 to 0.50, 3) building of a radiomic signature involving the resulting features using a linear discriminant analysis, 4) test of the model on the Nth patient, 5) characterization of the model performance using the Youden Index (Y=sensitivity+specificity-1). The final model selection was based on the consistency of Y values as a function of alpha and R, on the consistency of selected features between the different models, and favored models involving a low number of features. To test the reliability of the selected signature, we repeated the process by excluding one patient using a jackknife procedure (ie, 84 LOO of 83 patients each). We compared the results with those obtained with the same alpha and R when randomly assigning a label to each patient (sham task). Results: 61 patients had tumor recurrence and 23 had radiation necrosis. Visual interpretation yielded Y equal to 0.35 (Lizarraga scale, Se=100%, Sp=35%). Using LOO, 10/28 radiomic models had Y>0.35. The largest Y (Y=0.49, Se=62%, Sp=87%) were obtained with 4 features on average, reflecting the volume, sphericity and heterogeneity (GLCM_Correlation, GLCM_Contrast) of the lesion uptake. Using the jackknife procedure, Y was 0.47±0.06 (range: [0.32;0.56]), significantly higher (Wilcoxon p < 0.05) than for the sham task (Y=0.06±0.18, range: [-0.52;0.47]). Conclusion: The proposed systematic screening procedure enabled the identification of a parsimonious radiomic signature from scarce data. References: [1] Nioche et al. Cancer Res 2018.

Abstract: International audience; Importance:Risk of developing progressive multifocal leukoencephalopathy (PML) is the major barrier to using natalizumab for patients with multiple sclerosis (MS). To date, the association of risk stratification with PML incidence has not been evaluated.Objective:To describe the temporal evolution of PML incidence in France before and after introduction of risk minimization recommendations in 2013.Design, Setting, and Participants:This observational study used data in the MS registry OFSEP (Observatoire Français de la Sclérose en Plaques) collected between April 15, 2007, and December 31, 2016, by participating MS expert centers and MS-dedicated networks of neurologists in France. Patients with an MS diagnosis according to current criteria, regardless of age, were eligible, and those exposed to at least 1 natalizumab infusion (n = 6318) were included in the at-risk population. A questionnaire was sent to all centers, asking for a description of their practice regarding PML risk stratification. Data were analyzed in July 2018.Exposures:Time from the first natalizumab infusion to the occurrence of PML, natalizumab discontinuation plus 6 months, or the last clinical evaluation.Main Outcomes and Measures:Incidence was the number of PML cases reported relative to the person-years exposed to natalizumab. A Poisson regression model for the 2007 to 2016 period estimated the annual variation in incidence and incidence rate ratio (IRR), adjusted for sex and age at treatment initiation and stratified by period (2007-2013 and 2013-2016).Results:In total, 6318 patients were exposed to natalizumab during the study period, of whom 4682 (74.1%) were female, with a mean (SD [range]) age at MS onset of 28.5 (9.1 [1.1-72.4]) years; 45 confirmed incident cases of PML were diagnosed in 22 414 person-years of exposure. The crude incidence rate for the whole 2007 to 2016 period was 2.00 (95% CI, 1.46-2.69) per 1000 patient-years. Incidence significantly increased by 45.3% (IRR, 1.45; 95% CI, 1.15-1.83; P = .001) each year before 2013 and decreased by 23.0% (IRR, 0.77; 95% CI, 0.61-0.97; P = .03) each year from 2013 to 2016.Conclusions and Relevance:The results of this study suggest, for the first time, a decrease in natalizumab-associated PML incidence since 2013 in France that may be associated with a generalized use of John Cunningham virus serologic test results; this finding appears to support the continuation and reinforcement of educational activities and risk-minimization strategies in the management of disease-modifying therapies for multiple sclerosis.

Abstract: International audience; Event-related potentials (ERPs) are reproducible electrophysiological responses after the administrationof an external stimulus, e.g. visual, auditory. They appear as weak signals with low amplitude and signal-to-noise ratio, typically masked by noise and spontaneous EEG activity. Thus, the classical experimentalprotocol used to measure ERPs consists in multiple presentations of the same kind of stimulus: epochs,that is the EEG time series after the stimulus onset, are time-locked averaged so as to cancel out noiseand observe the desired waveform. An example of an ERP component is the P300, i.e. a positivedeflection appearing around 300 ms after the stimulus presentation, which is typically elicited by theoddball paradigm: sequences of repetitive stimuli (non-target) are infrequently interrupted by a deviantstimulus (target). The P300 component concerns the evaluation and categorization of a stimulus,allowing to discriminate the subject’s brain states. Thus, the different neural responses can be used toinvestigate dysfunctions in sensory and cognitive processing, as well as being a suitable tool for brain-computer interface. Hence, novel signal processing and machine learning algorithms are gaining groundto achieve robust automatic ERPs classification, and consequently a more extensive and practical use ofEEG.In the current study, we examined the performance of a LSTM network to classify P300 componentbetween target and non-target stimuli in an auditory oddball paradigm. EEG recordings of 19 channelsof two subjects were acquired during an auditory oddball paradigm with the 80% of the tones at a lowfrequency pitch, and the remaining 20% at a high frequency pitch. The signals were re-referenced withrespect to the mastoids and band-passed filtered between 0.1 and 30 Hz. After extracting the epochsand removing the baseline, visual inspection and rejection was performed to end up with a total of 324trials (200 from S1, 124 from S2). A different classification problem was considered for each electrode.Interval features derived from signal segments of various length were extracted. For each time i of theinterval, segments with length varying as the power of two are formed, by keeping always i as thestarting point and including the rest of the time series until the length of the interval exceeds the epoch.Then, for each interval the average amplitude and the standard deviation were calculated and used asfeatures to feed the network. A single layer Long Short-Term Memory (LSTM) network was defined,followed by fully connected layers and a softmax activation function. Two approaches were tested: asubject-dependent one, by using 75% of S1 samples as training set and the other 25% as test; a subject-independent one, by using 200 samples (100 S1 + 100 S2) as training set and the remaining ones as test.The mean classification accuracy over all the electrodes for the first approach was 81.16%, while for thesecond approach 75.55%. These results are in line with the previous literature studies, in whichrecurrent neural network outperformed other common algorithms, such as SVM. In particular, F3, F4,Fp1 and Fp2 presents globally the best accuracies. Indeed, P300 is typically stronger on the frontal lobes.Also, compared to other feature extraction methods, the interval feature extraction is intuitive and easy-to-implement, and does not rely on any other parameter. The results encourage the use of thisclassifier, but further analyses need to be done. For example, it would be interesting to collect data witha more balanced number of events – target occur always less than non-targets. Moreover, the intervalfeature extraction could be combined to other features, e.g. in the frequency domain, and fed to a LSTMbidirectional layer.

Abstract: Background Safety of HPV vaccines is still in question due to reports of autoimmune diseases (ADs) following HPV immunization. Objectives To assess the risk of ADs associated with HPV vaccination of female adolescents/young adults in France. Methods Systematic prospective case-referent study conducted to assess the risks associated with real-life use of HPV vaccines. Cases were female 11–25 years old with incident ADs [central demyelination/multiple sclerosis (CD/MS), connective tissue disease (CTD), Guillain-Barre syndrome (GBS), type-1 diabetes (T1D), autoimmune thyroiditis (AT), and idiopathic thrombocytopenic purpura (ITP)]. Cases were consecutively and prospectively identified at specialized centers across France (2008–2014) and individually matched by age and place of residence to referents recruited in general practice. Risk was computed using multivariate conditional logistic regression models adjusted for family history of ADs, living in France (north/south), co-medications and co-vaccinations. Results With a total of 478 definite cases matched to 1869 referents, all ADs combined were negatively associated to HPV vaccination with an adjusted odds ratio of 0.58 (95% confidence interval: 0.41–0.83). Similar results were obtained for CD/MS, AT, CT, and T1D, the last two not reaching statistical significance. No association was found for ITP and GBS. Sensitivity analyses combining definite and possible cases with secondary time window showed similar results. Conclusion Exposure to HPV vaccines was not associated with an increased risk of ADs within the time period studied. Results were robust to case definitions and time windows of exposure. Continued active surveillance is needed to confirm this finding for individual ADs.

Abstract: ObjectiveTo compare the clinical features of patients showing a classical phenotype of facioscapulohumeral muscular dystrophy (FSHD) with genetic and epigenetic characteristics of the FSHD1 and FSHD2 loci D4Z4 and SMCHD1.MethodsThis is a national multicenter cohort study. We measured motor strength, motor function, and disease severity by manual muscle testing sumscore, Brooke and Vignos scores, clinical severity score (CSS), and age-corrected CSS, respectively. We correlated these scores with genetic (D4Z4 repeat size and haplotype; SMCHD1 variant status) and epigenetic (D4Z4 methylation) parameters.ResultsWe included 103 patients: 54 men and 49 women. Among them, we identified 64 patients with FSHD1 and 20 patients with FSHD2. Seven patients had genetic and epigenetic characteristics of FSHD1 and FSHD2, all carrying repeats of 9–10 D4Z4 repeat units (RU) and a pathogenic SMCHD1 variant. In the remaining patients, FSHD was genetically excluded or remained unconfirmed. All clinically affected SMCHD1 mutation carriers had a D4Z4 repeat of 9–16 RU on a disease permissive 4qA haplotype. These patients are significantly more severely affected by all clinical scales when compared to patients with FSHD1 with upper-sized FSHD1 alleles (8–10 RU).ConclusionThe overlap between FSHD1 and FSHD2 patients in the 9–10 D4Z4 RU range suggests that FSHD1 and FSHD2 form a disease continuum. The previously established repeat size threshold for FSHD1 (1–10 RU) and FSHD2 (11–20 RU) needs to be reconsidered.Clinicaltrials.gov identifierNCT01970735.

Abstract: ObjectivesThe study aimed to assess the potential for serum neurofilament light chain (NFL) levels to predict the risk of progressive multifocal leukoencephalopathy (PML) in natalizumab (NTZ)-treated patients with multiple sclerosis (MS) and to discriminate PML from MS relapses.MethodsNFL levels were measured with single molecule array (Simoa) in 4 cohorts: (1) a prospective cohort of patients with MS who developed PML under NTZ therapy (pre-PML) and non-PML NTZ-treated patients (NTZ-ctr); (2) a cohort of patients whose blood was collected during PML; (3) an independent cohort of non-PML NTZ-treated patients with serum NFL determinations at 2 years (replication cohort); and (4) a cohort of patients whose blood was collected during exacerbations.ResultsSerum NFL levels were significantly increased after 2 years of NTZ treatment in pre-PML patients compared with NTZ-ctr. The prognostic performance of serum NFL levels to predict PML development at 2 years was similar in the NTZ-ctr group and replication cohort. Serum NFL levels also distinguished PML from MS relapses and were 8-fold higher during PML compared with relapses.ConclusionsThese results support the use of serum NFL levels in clinical practice to identify patients with relapsing-remitting MS at higher PML risk and to differentiate PML from clinical relapses in NTZ-treated patients.Classification of EvidenceThis study provides Class I evidence that serum NFL levels can identify NTZ-treated patients with MS who will develop PML with a sensitivity of 67% and specificity of 80%.

Abstract: Objective: To investigate the efficacy of rituximab as rescue therapy in patients with relapsing-remitting multiple sclerosis (RRMS) and persistent disease activity confirmed by magnetic resonance imaging (MRI) despite immunosuppressive disease-modifying therapy (DMT). Methods: In this observational nationwide retrospective multicenter study, we first identified 351 off-label rituximab-treated patients through a cohort of 15,984 RRMS patients. In this group, we identified patients with disease activity prior to rituximab confirmed by MRI (one or more new T2 lesion and/or gadolinium-enhancing lesion) despite immunosuppressive DMT (fingolimod, natalizumab, or mitoxantrone) with a follow-up after rituximab initiation longer than 6 months. Outcome data were collected from the French Observatory of Multiple Sclerosis (OFSEP) register and medical charts. Results: A total of 50 patients were identified. Median rituximab treatment duration was 1.1 (0.5–6.4) year. Mean annualized relapse rate significantly decreased from 0.8 during last immunosuppressive DMT to 0.18 after rituximab ( p Conclusion: This study provides level IV evidence that rituximab reduces clinical and MRI disease activity in patients with active RRMS despite immunosuppressive DMT.

Abstract: Background: Younger age, male sex and presence of spinal cord lesion(s) increase the risk of conversion from radiologically isolated syndrome (RIS) to relapsing-remitting multiple sclerosis (RRMS). Elevated cerebrospinal fluid (CSF) chitinase-3-like protein 1 (CHI3L1) levels predict conversion from clinically isolated syndrome (CIS) to RRMS. Objective: To evaluate the prognostic value of CSF CHI3L1 in RIS patients for conversion to RRMS. Methods: We compared CSF CHI3L1 concentrations in RIS, CIS, RRMS and symptomatic controls (SCs). We analysed the influence of epidemiological, radiological and CSF parameters on the risk of clinical event. Results: A total of 211 patients (71 RIS, 48 CIS, 50 RRMS and 42 SC) were included. CSF CHI3L1 levels were lower in RIS than in RRMS and higher in RIS with positive CSF versus negative CSF and SC. The presence of at least one spinal cord lesion was the only independent predictor of faster conversion to RRMS. Association of high CSF CHI3L1 levels, positive CSF (presence of oligoclonal bands and/or an elevated IgG index) or four Barkhof criteria with any spinal cord lesion showed a tendency for reduced mean conversion time. Conclusion: CSF CHI3L1 correlates with positive CSF but is not an independent predictor of the risk of conversion from RIS to RRMS.

Abstract: Objective:To describe clinical and radiologic outcomes of children with incidental findings on neuroimaging suggestive of CNS demyelination (termed “radiologically isolated syndrome” or RIS).Methods:Clinical and radiologic data were obtained from a historical cohort of children with no symptoms of demyelinating disease who had MRI scans that met the 2010 MRI criteria for dissemination in space for MS.Results:We identified 38 children (27 girls and 11 boys) with RIS now being prospectively followed at 16 sites in 6 countries. The mean follow-up time was 4.8 ± 5.3 years. The most common reason for initial neuroimaging was headache (20/38, 53%). A first clinical event consistent with CNS demyelination occurred in 16/38 children (42%; 95% confidence interval [CI]: 27%–60%) in a median of 2.0 years (interquartile range [IQR] 1.0–4.3 years). Radiologic evolution developed in 23/38 children (61%; 95% CI: 44%–76%) in a median of 1.1 years (IQR 0.5–1.9 years). The presence of ≥2 unique oligoclonal bands in CSF (hazard ratio [HR] 10.9, 95% CI: 1.4–86.2, p = 0.02) and spinal cord lesions on MRI (HR 7.8, 95% CI: 1.4–43.6, p = 0.02) were associated with an increased risk of a first clinical event after adjustment for age and sex.Conclusions:We describe the clinical characteristics and outcomes of children with incidental MRI findings highly suggestive of CNS demyelination. Children with RIS had a substantial risk of subsequent clinical symptoms and/or radiologic evolution. The presence of oligoclonal bands in CSF and spinal cord lesions on MRI were associated with an increased risk of a first clinical event.

Abstract: International audience; OBJECTIVE:Despite its well-known effectiveness, the cost-effectiveness of epilepsy surgery has never been demonstrated in France. We compared cost-effectiveness between resective surgery and medical therapy in a controlled cohort of adult patients with partial intractable epilepsy.METHODS:A prospective cohort of adult patients with surgically remediable and medically intractable partial epilepsy was followed over 5 years in the 15 French centers. Effectiveness was defined as 1 year without a seizure, based on the International League Against Epilepsy (ILAE) classification. Clinical outcomes and direct costs were compared between surgical and medical groups. Long-term direct costs and effectiveness were extrapolated over the patients' lifetimes with a Monte-Carlo simulation using a Markov model, and an incremental cost-effectiveness ratio (ICER) was computed. Indirect costs were also evaluated.RESULTS:Among the 289 enrolled surgery candidates, 207 were operable-119 in the surgical group and 88 in the medical group-65 were not operable and not analyzed here, 7 were finally not eligible, and 10 were not followed. The proportion of patients completely seizure-free during the last 12 months (ILAE class 1) was 69.0% in the operated group and 12.3% in the medical group during the second year (p < 0.001), and it was respectively 76.8% and 21% during the fifth year (p < 0.001). Direct costs became significantly lower in the surgical group the third year after surgery, as a result of less antiepileptic drug use. The value of the discounted ICER was 10,406 (95% confidence interval [CI] 10,182-10,634) at 2 years and 2,630 (CI 95% 2,549-2,713) at 5 years. Surgery became cost-effective between 9 and 10 years after surgery, and even earlier if indirect costs were taken into account as well.SIGNIFICANCE:Our study suggests that in addition to being safe and effective, resective surgery of epilepsy is cost-effective in the medium term. It should therefore be considered earlier in the development of epilepsy.

Abstract: International audience; ObjectiveThe discovery of mutations in DEPDC5 in familial focal epilepsies has introduced a novel pathomechanism to a field so far dominated by ion channelopathies. DEPDC5 is part of a complex named GAP activity toward RAGs (GATOR) complex 1 (GATOR1), together with the proteins NPRL2 and NPRL3, and acts to inhibit the mechanistic target of rapamycin (mTOR) complex 1 (mTORC1) pathway. GATOR1 is in turn inhibited by the GATOR2 complex. The mTORC1 pathway is a major signaling cascade regulating cell growth, proliferation, and migration. We aimed to study the contribution of GATOR complex genes to the etiology of focal epilepsies and to describe the associated phenotypical spectrum.MethodsWe performed targeted sequencing of the genes encoding the components of the GATOR1 (DEPDC5, NPRL2, and NPRL3) and GATOR2 (MIOS, SEC13, SEH1L, WDR24, and WDR59) complex in 93 European probands with focal epilepsy with or without focal cortical dysplasia. Phospho-S6 immunoreactivity was used as evidence of mTORC1 pathway activation in resected brain tissue of patients carrying pathogenic variants.ResultsWe identified four pathogenic variants in DEPDC5, two in NPRL2, and one in NPRL3. We showed hyperactivation of the mTORC1 pathway in brain tissue from patients with NPRL2 and NPRL3 mutations. Collectively, inactivating mutations in GATOR1 complex genes explained 11% of cases of focal epilepsy, whereas no pathogenic mutations were found in GATOR2 complex genes. GATOR1-related focal epilepsies differ clinically from focal epilepsies due to mutations in ion channel genes by their association with focal cortical dysplasia and seizures emerging from variable foci, and might confer an increased risk of sudden unexplained death in epilepsy (SUDEP).SignificanceGATOR1 complex gene mutations leading to mTORC1 pathway upregulation is an important cause of focal epilepsy with cortical malformations and represents a potential target for novel therapeutic approaches.

Abstract: BACKGROUND: Recent studies in multiple sclerosis (MS) showed longer survival times from clinical onset than older hospital-based series. However estimated median time ranges widely, from 24 to 45 years, which makes huge difference for patients as this neurological disease mainly starts around age 20 to 40. Precise and up-to-date reference data about mortality in MS are crucial for patients and neurologists, but unavailable yet in France. OBJECTIVES: Estimate survival in MS patients and compare mortality with that of the French general population. METHODS: We conducted a multicenter observational study involving clinical longitudinal data from 30,413 eligible patients, linked to the national deaths register. Inclusion criteria were definite MS diagnosis and clinical onset prior to January, 1st 2009 in order to get a minimum of 1-year disease duration. RESULTS: After removing between-center duplicates and applying inclusion criteria, the final population comprised 27,603 MS patients (F/M sex ratio 2.5, mean age at onset 33.0 years, 85.5% relapsing onset). During the follow-up period (mean 15.2 +/- 10.3 years), 1569 deaths (5.7%) were identified; half related to MS. Death rates were significantly higher in men, patients with later clinical onset, and in progressive MS. Overall excess mortality compared with the general population was moderate (Standardized Mortality Ratio 1.48, 95% confidence interval [1.41-1.55]), but increased considerably after 20 years of disease (2.20 [2.10-2.31]). CONCLUSIONS: This study revealed a moderate decrease in life expectancy in MS patients, and showed that the risk of dying is strongly correlated to disease duration and disability, highlighting the need for early actions that can slow disability progression. journal article multicenter study observational study research support, non-u.s. gov't 2015 2015 07 06 imported

Abstract: BACKGROUND: 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. OBJECTIVE: To compare CPM to methylprednisolone (MP) in SPMS. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

Abstract: International audience; Functional and connectivity changes in corticostriatal systems have been reported in the brains of patients with obsessive-compulsive disorder (OCD); however, the relationship between basal ganglia activity and OCD severity has never been adequately established. We recently showed that deep brain stimulation of the subthalamic nucleus (STN), a central basal ganglia nucleus, improves OCD. Here, single-unit subthalamic neuronal activity was analysed in 12 OCD patients, in relation to the severity of obsessions and compulsions and response to STN stimulation, and compared with that obtained in 12 patients with Parkinson's disease (PD). STN neurons in OCD patients had lower discharge frequency than those in PD patients, with a similar proportion of burst-type activity (69 vs 67%). Oscillatory activity was present in 46 and 68% of neurons in OCD and PD patients, respectively, predominantly in the low-frequency band (1-8 Hz). In OCD patients, the bursty and oscillatory subthalamic neuronal activity was mainly located in the associative-limbic part. Both OCD severity and clinical improvement following STN stimulation were related to the STN neuronal activity. In patients with the most severe OCD, STN neurons exhibited bursts with shorter duration and interburst interval, but higher intraburst frequency, and more oscillations in the low-frequency bands. In patients with best clinical outcome with STN stimulation, STN neurons displayed higher mean discharge, burst and intraburst frequencies, and lower interburst interval. These findings are consistent with the hypothesis of a dysfunction in the associative-limbic subdivision of the basal ganglia circuitry in OCD's pathophysiology.

Abstract: BACKGROUND: Mutations in the LRRK2 gene, the most frequent of which is the G2019S mutation in exon 41, cause familial and sporadic Parkinson's disease (PD) with reduced penetrance. OBJECTIVES: To assess the frequency of the LRRK2 G2019S mutation in families thought to have autosomal recessive PD (siblings but not their parents were affected) and to determine the clinical features of LRRK2 mutation carriers. METHODS: We sequenced both strands of exon 41 of the LRKK2 gene in 90 index cases from French and North African families in which PD might have been inherited as a recessive trait. Patients with mutations underwent detailed clinical evaluations. RESULTS: We found heterozygous G2019S mutations in 1 Algerian and 1 French family (overall relative frequency = 2.2%). Four LRRK2-positive patients had typical PD, but their Mini Mental State Examination (MMSE) scores were lower than those of patients without this mutation. CONCLUSION: The LRRK2 G2019S mutation is as frequent in families with possible autosomal recessive PD (2.2%) as in the sporadic cases published elsewhere (1.9%). The clinical features in the LRRK2-positive patients were those of typical PD, except for lower MMSE scores.

40. [The contribution of automatic anatomical matching of sequential brain MRI scans in the monitoring of multiple sclerosis lesions].

Author: Lebrun C, Rey D, Chanalet S, Bourg V, Bensa C, Chatel M, Ayache N, and Malandain G
Subjects: Adolescent, Adult, Female, Humans, Male, Middle Aged, Magnetic Resonance Imaging methods, Multiple Sclerosis diagnosis
Abstract: Introduction: Magnetic resonance imaging (MRI) has transformed management of patients with multiple sclerosis. The exact contribution of brain MRI remains a subject of debate, but it is generally considered to provide a more specific and more sensitive outcome measure for monitoring purposes and for testing new therapies. The choice of MRI techniques, and measurement reproducibility for multiple sclerosis brain lesions are not defined with precision for routine practice. There are many sources of error when comparing successive images which can be overcome to some extent with repositioning and image processing techniques., Methods: We evaluated the impact of image repositioning on treatment decision-making for twelve relapsing remitting patients. Brain MRIs were performed every three months for a one-year period. Two neurologists interpreted the non-repositioned and repositioned images giving their analysis of changes in the lesions visualized on the T2 sequences and their therapeutic decisions., Results: For the first neurologist, analysis of the non-repositioned images yielded six patients whose lesions had worsened while for the repositioned images there were only three. For the second neurologist, four patients had more lesions with the non-repositioned images and only three with repositioning. The subjective interpretations were the same for the two neurologists when they used repositioned images., Conclusions: Comparison by two neurologists of non-repositioned and repositioned MRI, with no other image processing, affected the analysis and in certain cases propositions for treatment.

41. Voxel-based mapping of cortical ischemic damage using Tc 99m L,L-ethyl cysteinate dimer SPECT in acute stroke.

Abstract: Background and Purpose: When performed soon after stroke onset, single-photon emission computed tomography (SPFCT) with hexamethylpropylenamine oxime or Tc 99m L,L-ethyl cysteinate dimer (ECD) has significant added predictive value compared to neurological scores. With ECD SPECT, the degree of tracer uptake reduction predicts neurological recovery, and using a 40% threshold to characterize irreversibly damaged tissue (IDT), significant correlations have been observed. However, correlations between this uptake threshold and tissue outcomes have not been assessed. The purpose of this study was to validate the 40% ECD uptake threshold for the probabilistic mapping of IDT using an automatic, voxel-based approach., Methods: In 10 acute stroke patients, the authors first compared early ECD SPECT and late coregistered magnetic resonance imaging (MRI) data and assessed for IDT and "tissue at risk" (i.e., tissue with ECD uptake below and above 40%) the percentage of voxels ultimately infarcted and noninfarcted on late brain MRI. They then assessed the correlations between the volumes of brain tissue compartments and subsequent neurological recovery. Finally, to assess whether visual SPECT analysis is reliable compared to the more complex voxel-based approach, the authors compared the predictive value of the 2 methods for neurological recovery., Results: The majority of IDT voxels (average = 84%), defined by ECD uptake < 40%, evolved toward infarction, and 51.8% to 100% of at-risk voxels (average = 89%) escaped infarction. The extent of IDT correlated significantly with neurological recovery (P = .0009). There was good agreement between visual and voxel-based analyses (P = .0004)., Conclusion: The results support the validity of the ECD uptake thresholds chosen, suggesting that ECD uptake can reflect neuronal viability and that ECD SPECT can be useful for the early detection of potentially salvageable tissue and irreversible damage. These preliminary results encourage the use of this method in a clinical setting for fast decision making in choosing acute therapy.

42. [Castleman's disease located in the central nervous system].

Author: Delmont E, Lonjon M, Michiels JF, Chanalet S, Bourg V, Xerri L, Bondiau PY, and Lebrun C
Subjects: Adult, Antigens, CD immunology, Castleman Disease immunology, Castleman Disease surgery, Diplopia etiology, Exophthalmos etiology, Female, Humans, Magnetic Resonance Imaging, Trigeminal Neuralgia etiology, Castleman Disease pathology, Temporal Lobe pathology
Abstract: A 26-year-old woman complained of trijeminal nevralgy and ocular symptoms revealing a paracavernal tumor which had progressed for three months. Histopathological analysis after partial resection led to the diagnosis of Castleman's disease. Six months later, the patient was considered cured after focal adjuvant radiotherapy. Castleman's disease is a lymphoproliferative disorder. Solitary intracranial involvement is unusual. Unlike multifocal disease, localized Castleman's disease has an excellent prognosis.

Abstract: Multiple sclerosis is a demyelinating disease of central nervous system. Although many sub-types and clinical forms are identified, diagnosis is clearly related to the detection of MS lesions on brain MRI. We report data of 15 patients admitted in Nice for suspicion of MS after clinical relapsing-remitting or progressive symptoms. Extensive screening tests (i.e blood sample, CSF, MRI, spectroscopy) were performed at onset and at each relapse. All patients had normal-appearing white matter on spinal cord and brain MRI. Nevertheless, 11 patients can be considered as MS according to McDonald criteria.

44. [Neurologic complications of chemotherapy].

Author: Lebrun C, Frenay M, and Lanteri-Minet M
Subjects: Humans, Neoplasms drug therapy, Quality of Life, Antineoplastic Agents adverse effects, Nervous System Diseases chemically induced
Abstract: Introduction: Neurotoxicity can be induced by the synergistic or additive effects of cytotoxic treatments, and nervous system exposure is related to routes and doses., Current Knowledge and Key Points: The improvements in treating systemic malignancy have been accompanied by reports of neurologic toxicity, which has an important impact on the quality of life and may even limit the use of the treatment., Perspectives and Future Projects: It demands out a continuous clinical evaluation to detect their appearance. When neurological complications are diagnosed later, they are rarely reversible. Neuroprotective agents are still being evaluated.

45. Chemotherapy and immunotherapy in adult malignant gliomas.

Author: Chatel M, Lebrun C, and Frenay M
Subjects: Adult, Animals, Astrocytoma drug therapy, Astrocytoma therapy, Chemotherapy, Adjuvant, Clinical Trials, Phase II as Topic, Humans, Oligodendroglioma drug therapy, Oligodendroglioma therapy, Randomized Controlled Trials as Topic, Brain Neoplasms drug therapy, Brain Neoplasms therapy, Glioma drug therapy, Glioma therapy, Immunotherapy
Abstract: This review summarizes papers published during 1991 and 1992. The poor results obtained in the postneurosurgical treatment of gliomas led researchers to pursue attempts to try to overcome glioma cell resistance. The intra-arterial route was explored in several phase II studies with new drugs and even immunoconjugates; rates of response between 30% to 60% were obtained. New drugs (fotemustine, eflornithine, and estramustine) or combined protocols planned to circumvent chemoresistance were tested and showed some efficiency with moderate toxicity, enlarging the number of drugs available against malignant gliomas. On the contrary, two retrospective analyses warned about the risk of reduction of median time to survival due to adjuvant chemotherapy in anaplastic astrocytomas; this finding, if confirmed, would suggest to defer chemotherapy at the time of recurrence in this type of glial tumor. Immunobiologic therapies as immunomodifiers, immunoconjugates, or cytotoxic lymphocyte-activated killer cells and tumor-infiltrating lymphocytes were tested and allowed some responses to be obtained. In young children, chemotherapy regimens were found to be efficient in malignant plexus choroid carcinomas and low-grade gliomas, allowing radiation therapy to be deferred. Many studies were methodologically unsatisfactory because of uncertain pathology grouping, noncompliance to initial protocols, or too small populations of patients.
