Objective:To determine the cumulative incidence of epilepsy in a population-based cohort of patients with multiple sclerosis (MS) and to investigate the association between epilepsy and clinical features of MS.Methods:All available patients in the Swedish MS register (n = 14,545) and 3 age- and sex-matched controls per patient randomly selected from the population register (n = 43,635) were included. Data on clinical features of MS were retrieved from the Swedish MS register, and data on epilepsy and death were retrieved from comprehensive patient registers.Results:The cumulative incidence of epilepsy was 3.5% (95% confidence interval [CI] 3.17–3.76) in patients with MS and 1.4% (95% CI 1.30–1.52) in controls (risk ratio 2.5, 95% CI 2.19–2.76). In a Cox proportional model, MS increased the risk of epilepsy (hazard ratio 3.2, 95% CI 2.64–3.94). Patients with relapsing-remitting MS had a cumulative incidence of epilepsy of 2.2% (95% CI 1.88–2.50), whereas patients with progressive disease had a cumulative incidence of 5.5% (95% CI 4.89–6.09). The cumulative incidence rose continuously with increasing disease duration to 5.9% (95% CI 4.90–7.20) in patients with disease duration ≥34 years. Patients with an Expanded Disability Status Scale (EDSS) score ≥7 had a cumulative incidence of epilepsy of 5.3% (95% CI 3.95–7.00). Disease duration and EDSS score were associated with epilepsy after multiple logistic regression (odds ratio [OR] 1.03, 95% CI 1.01–1.04 per year, p = 0.001; and OR 1.2, 95% CI 1.09–1.26 per EDSS step, p < 0.0001).Conclusions:Epilepsy is more common among patients with MS than in the general population, and a diagnosis of MS increases the risk of epilepsy. Our data suggest a direct link between severity of MS and epilepsy.

Activity Prognosis

Early multiple sclerosis (MS) predictive markers of disease activity/prognosis have been proposed but are not universally accepted. Aim of this pilot prospective study is to verify whether a peculiar hyperactivity, observed at baseline (T0) in early relapsing-remitting (RR) MS patients, could represent a further prognostic marker. Here we report results collected at T0 and at a 24-month follow-up (T1). Eighteen RRMS patients (11 females, median Expanded Disability Status Scale-EDSS score 1.25, range EDSS score 0–2) were monitored at T0 (mean age 32.33 ± 7.51) and T1 (median EDSS score 1.5, range EDSS score 0–2.5). Patients were grouped into two groups: responders (R, 14 patients) and non-responders (NR, 4 patients) to treatment at T1. Each patient wore an actigraph for one week to record the 24-h motor activity pattern. At T0, NR presented significantly lower motor activity than R between around 9:00 and 13:00. At T1, NR were characterized by significantly lower motor activity than R between around 12:00 and 17:00. Overall, these data suggest that through the 24-h motor activity pattern, we can fairly segregate at T0 patients who will show a therapeutic failure, possibly related to a more active disease, at T1. These patients are characterized by a reduced morning level of motor activation. Further studies on larger populations are needed to confirm these preliminary findings.

Although neuromyelitis optica (NMO) is known to be a more severe disease than relapsing-remitting multiple sclerosis (RRMS), few studies comparing both conditions in a single center have been done.Methods:Comparison of our previously published cohort of 41 NMO patients with 177 RRMS patients followed in the same center, from 1994 to 2007.Results:Mean age of onset was 32.6 for NMO and 30.2 for RRMS (p=0.2062) with mean disease duration of 7.4 years for NMO and 10.3 years for RRMS. Patients with NMO had a higher annualized relapse rate (1.0 versus 0.8, p=0.0013) and progression index (0.9 versus 0.6, p≪0.0001), with more patients reaching expanded disability status scale (EDSS) 6.0 (39 versus 17%, p=0.0036). The odds ratio for reaching EDSS 6.0 and being deceased due to NMO in comparison to RRMS were, respectively, 3.14 and 12.15.Conclusion:Patients with NMO have a more severe disease than patients with RRMS, including higher risk of dying of a demyelinating disease.

We linked several population-based clinical and health administrative databases in British Columbia, Canada. We identified and compared birth outcomes of pregnancies fathered by men with multiple sclerosis (MS) ( n=202) and men from a frequency-matched general population cohort ( n=981) between 1996 and 2010. Using multivariate models, we analyzed the association of paternal MS, disease duration at conception and disability (as measured by the Expanded Disability Status Scale) with birth weight and gestational age. Paternal MS and MS-related clinical factors were not significantly associated with birth outcomes ( p>0.05). This study provides assurance to expecting fathers with MS and their families.

Background: Pregnancy is considered to influence the disease course in women with multiple sclerosis (MS). Objective: The aim of this study was to investigate the effect of pregnancy on long-term disability accrual in women with MS. Methods: The Danish Multiple Sclerosis Registry (DMSR) was used to identify women diagnosed with clinically isolated syndrome or relapsing-remitting MS. Cox models with pregnancy as a time-dependent exposure and propensity score (PS) models were used to evaluate time to reach confirmed Expanded Disability Status Scale (EDSS) score of 4 and 6. Results: A total of 425 women became parous and 840 remained nulliparous. When including pregnancy as a time-dependent exposure, a non-significant association with time to reach EDSS 4 (hazard ratio (HR) 0.86, 95% confidence interval (CI) 0.61–1.20) and EDSS 6 (HR 0.70, 95% CI 0.40–1.20) was found. Correspondingly, the PS model showed no association with pregnancy on time to reach EDSS 4 (HR 0.85, 95% CI 0.56–1.28). Conclusion: This study concludes that pregnancy does not affect long-term disability accumulation.

Previous studies have shown a preferential loss of grey matter in fronto-temporal regions in patients with multiple sclerosis. Studies of correlates of disease severity are more controversial, because some studies have suggested an association between sensorimotor cortex atrophy and Expanded Disability Status Scale score, while others did not find such a correlation. The objective of this study was to assess the correlation of regional loss of grey matter and white matter with indexes of clinical and radiological severity in relapsing—remitting multiple sclerosis, including the Expanded Disability Status Scale and lesion load. Correlations between Expanded Disability Status Scale, lesion load and disease duration were assessed in 128 patients with relapsing—remitting multiple sclerosis (Expanded Disability Status Scale range 1.0—6.0) using optimized voxel-based morphometry. Bilateral loss of grey matter in sensorimotor cortices was correlated with Expanded Disability Status Scale, and tissue loss also involved adjacent white matter, extending along pyramidal tracts to the brainstem. Increasing lesion load was correlated with loss of deep grey matter and white matter. No specific region of grey matter or white matter showed a significant correlation with disease duration. These findings support the hypothesis that motor neuron involvement plays a major role in the progression of physical disability. Lesion load accrual affects mainly highly interconnected subcortical structures, while disease duration has a less significant impact on brain atrophy, probably owing to the inter-subject heterogeneity of the clinical course of the disease.

Introduction. The Expanded Disability Status Scale (EDSS) is the most widely used disability measure in multiple sclerosis (MS). The effect of fatigability on EDSS components has been underreported to date. Objective We investigated daytime variability in EDSS score and EDSS components - functional scores (FS) and walking distance (WD) up to 500 m, in MS patients who underwent a standardized fatiguing exercise. Methods. Twenty-four patients with relapsing-remitting MS (n = 7), secondary-progressive MS (n = 8) and primary-progressive MS (n = 9) were included. Exclusion criteria were as follows: current MS relapse, infection/fever/flu-like symptoms, conditions prohibiting safe exercise testing, current medication affecting fatigue. One trained examiner performed baseline (BL) and follow-up (FU) assessments (FU1 after a standardized fatiguing exercise, FU2 after rest) over a single day. EDSS score change of ?1 point if BL EDSS score was <5.5 or of ?0.5 point if BL EDSS score was ?5.5 were considered clinically meaningful. Results. In progressive MS subtypes, WD decreased at FU1, but recovered at FU2, more so in secondaryprogressive MS subgroup with the highest BL EDSS score. Although BL EDSS scores (median, 5.0; range 4.0-6.5) and FS remained relatively stable over repeated assessments in the total group, a clinically meaningful transitory post-exercise EDSS score increase was observed in three patients with progressive MS. Conclusion. WD seems to be more influenced by fatigability than the total EDSS score, more so in patients with progressive MS and higher disability. WD should be assessed after rest and this strategy should be implemented into protocols of clinical trials recruiting patients with progressive MS phenotypes.

Abstract Background: Expanded Disability Status Scale (EDSS) scores of 4.0 or greater are determined primarily by maximum walking distance (MWD). Estimation of MWD by persons with multiple sclerosis (MS) is often used due to the impracticality of formally walking a person with MS in a clinic setting. Previous studies have demonstrated discrepancies between estimated and actual MWDs. Whether Timed 25-Foot Walk test (T25FW) values can be used to predict MWD is currently unknown. This study aimed to determine whether T25FW time is predictive of MWD in persons with MS. Methods: This study is a post hoc analysis of a previously described prospective cohort study. Persons with MS with an EDSS score of 3.5 to 5.5 were included. The participant’s T25FW values and MWD were measured. Results: Of the 38 adult participants (mean age, 50.8 years; 27 women [71%]), 24 (63%) had relapsing-remitting MS. The median EDSS score was 4.5 (range, 3.5–5.5). The T25FW times were divided into seven categories (&lt;5.0, 5.0–5.9, 6.0–6.9, 7.0–7.9, 8.0–8.9, 9.0–9.9, and ≥10.0 seconds). The MWDs were divided into corresponding EDSS score categories: ≥500, 300–499, 200–299, 100–199, and ≤99 m. Ordinal logistic regression, when controlled for age, found the T25FW categories to be predictive of EDSS score (χ2 = 17.630, df = 7, P = .014). Conclusions: The T25FW value may be used as a surrogate estimate of MWD. Further studies are needed to confirm the reliability of the T25FW in predicting MWD.

ABSTRACTObjectives: The objectives of this study were to assess the prevalence of temporomandibular disorders (TMDs) in patients with relapsing-remitting multiple sclerosis (MS) and to investigate whether an association exists between the presence of TMD symptoms and the degree of MS-related disability. Materials and Methods: In all, 120 individuals were evaluated: 60 patients with a diagnosis of relapsing-remitting MS and 60 age- and sex-matched controls without neurological impairments. A questionnaire recommended by the European Academy of Craniomandibular Disorders for the assessment of TMD symptoms was administered. For those who answered affirmatively to at least one of the questions, the RDC/TMD Axis I instrument was used for a possible classification of TMD subtypes. The Expanded Disability Status Scale (EDSS) was the measure of the degree of MS-related disability. Statistical Analysis Used: Fisher’s exact test was used to analyze the data. ANOVA was used to detect significant differences between means and to assess whether the factors influenced any of the dependent variables by comparing means from the different groups. Results: The prevalence of TMD symptoms in patients with MS was 61.7% versus 18.3% in the control group (CG). A diagnosis of TMD was established for 36.7% in the MS group and 3.3% in the CG (P = 0.0001). There were statistically significant differences between degrees of MS-related disability and the prevalence of TMD (P = 0.0288). Conclusions: The prevalence of both TMD and TMD symptoms was significantly greater in the MS group. EDSS scores and TMD prevalence rates were inversely related.

Objective To investigate levels of regulatory B (Breg) cells, plasma cells, and memory B cells in the peripheral blood, and interleukin (IL)-10 in the serum of multiple sclerosis (MS) patients, and to determine the correlation between Breg cell levels and the Expanded Disability Status Scale (EDSS) score. Methods Levels of Breg cells, plasma cells, and memory B cells in the peripheral blood of 12 MS patients were measured using flow cytometry. IL-10 serum levels were measured by enzyme-linked immunosorbent assay. The correlation between Breg cell levels and MS EDSS score was measured using Pearson’s correlation coefficient. Results Compared with healthy controls, MS patients had decreased levels of CD19+CD24hiCD38hi Breg cells in their peripheral blood and reduced serum levels of IL-10; however, the ratios of CD19+CD27hiCD38hi plasma cells and CD19+CD27+CD24hi memory B cells to total B cells did not differ significantly between healthy controls and MS patients. CD19+CD24hiCD38hi Breg cell levels in the peripheral blood of MS patients were not significantly correlated with MS EDSS score. Conclusion Peripheral blood CD19+CD24hiCD38hi Breg cell levels and serum IL-10 levels were reduced in MS patients compared with controls, but Breg cell levels were not correlated with MS EDSS score.

Abstract Background: There is no consensus regarding assessment of the brain function functional system (FS) of the Expanded Disability Status Scale (EDSS) in patients with multiple sclerosis (MS). We sought to describe brain function FS assessment criteria used by Argentinian neurologists and, based on the results, propose redefined brain function FS criteria. Methods: A structured survey was conducted of 113 Argentinian neurologists. Considering the survey results, we decided to redefine the brain function FS scoring using the Brief International Cognitive Assessment for MS (BICAMS) battery. For 120 adult patients with MS we calculated the EDSS score without brain function FS (basal EDSS) and compared it with the EDSS score after adding the modified brain function FS (modified EDSS). Results: Of the 93 neurologists analyzed, 14% reported that they did not assess brain function FS, 35% reported that they assessed it through a nonstructured interview, and the remainder used other tools. Significant differences were found in EDSS scores before and after the inclusion of BICAMS (P &lt; .001). Redefining the brain function FS, 15% of patients modified their basal EDSS score, as did 20% of those with a score of 4.0 or less. Conclusions: The survey results show the importance of unifying the brain function FS scoring criteria in calculating the EDSS score. While allowing more consistent brain function FS scoring, including the modified brain function FS led to a change in EDSS score in many patients, particularly in the lower range of EDSS scores. Considering the relevance of the EDSS for monitoring patients with MS and for decision making, it is imperative to further validate the modified brain function FS scoring.
