    ABSTRACT: Cognitive impairment affects half of the multiple sclerosis (MS) patient population and is an important contributor to patients' daily activities. Most cognitive impairment studies in MS are, however, cross-sectional or/and focused on the early disease stages.OBJECTIVE: We aim to assess the time course of decline of different cognitive domains.METHODS: We collected neuropsychological data on 514 MS patients to construct Kaplan-Meier survival curves of the tests included in the Neuropsychological Screening Battery for MS (NSBMS) and the Symbol Digit Modalities Test (SDMT). Cox-proportional hazard models were constructed to examine the influence of MS onset type, age at onset, gender, depression and level of education on the time course, expressed as age or disease.RESULTS: Survival curves of tests focusing on information processing speed (IPS) declined significantly faster than tests with less specific demands of IPS. Median age for pathological decline was 56.2 years (95% CI: 54.4-58.2) on the SDMT and 63.9 years (95% CI: 60-66.9) on the CLTR, a memory task.CONCLUSION: In conclusion, IPS is the cognitive domain not only most widely affected by MS but it is also the first cognitive deficit to emerge in MS.

    ABSTRACT: There is accumulating data suggesting an association between serum lipids, apolipoproteins and disability in multiple sclerosis (MS). To investigate the associations between serum lipids, apolipoproteins and disability in MS. A cohort of 178 participants with clinically-definite MS in southern Tasmania, Australia were prospectively followed from 2002 - 2005, and serum samples were obtained at study entry and at each biannual review, to measure lipid profile and apolipoprotein levels. Associations with disability and annual change in disability were evaluated using linear regression and multilevel mixed-effects linear regression. In the unadjusted analyses, nearly all lipid-related variables were positively associated with Expanded Disability Status Scale (EDSS). After adjustment for confounders, total cholesterol (TC) (p = 0.037), apolipoprotein B (ApoB) (p = 0.003), and the apolipoprotein B to apolipoprotein A-I ratio (ApoB/ApoA-I ratio) (p = 0.018) were independently associated with a higher EDSS. Higher body mass index (BMI) was also independently associated with higher EDSS (p = 0.013). With the progression analysis, the total cholesterol to high density lipoprotein (HDL) ratio (TC/HDL ratio) (p = 0.029) was prospectively associated with subsequent change in EDSS. In this prospective population-based cohort study, an adverse lipid profile was associated with high levels of MS disability and disease progression. Improving serum lipids may be beneficial for MS patients, to potentially improve clinical outcomes and vascular comorbidities.

    ABSTRACT: Neuromyelitis optica (NMO), or Devic's disease, is a rare demyelinating disorder of the central nervous system that has a predilection for the optic nerve and spinal cord. Magnetic resonance imaging (MRI) is required to diagnose NMO. Longitudinally extensive transverse myelitis is NMO's imaging hallmark and the presence of a brain MRI that is not diagnostic of multiple sclerosis (MS) also remains part of the diagnostic criteria. It is increasingly recognised that MS and NMO brain imaging can, however, have similar appearances but differences do exist: hypothalamic, periaqueductal grey and area postrema lesions implicate NMO whilst cortical, U-fibre or Dawson's finger lesions are suggestive of MS. The timing of image acquisition, age, ethnicity and aquaporin-4 antibody status are all likely to alter the findings at MRI. This review therefore aims to overview and update the reader on NMO imaging, to provide clinically relevant guidance for diagnosing NMO and differentiating it from MS in order to guide management, and to highlight recent research insights.

    ABSTRACT: Interleukin-7 (IL-7) is a non-redundant cytokine for T-cell development and survival. The IL-7 signaling pathway has been genetically and functionally associated with several autoimmune diseases including multiple sclerosis (MS). The objective of this paper is to elucidate the effect of the widely used immunomodulatory MS therapy interferon beta (IFNβ) on IL-7 homeostasis. Swedish MS patients were screened for IL-7 concentration in serum and blood cell counts. IL-7 receptor alpha chain (IL-7Rα) expression was determined by semi-quantitative real-time polymerase chain reaction (PCR) and flow cytometry. IFNβ treatment led to significantly increased serum IL-7 levels (mean: 17 pg/ml) compared with healthy controls (mean: 7.6 pg/ml) and natalizumab-treated patients (mean: 5.3 pg/ml). In vitro and in vivo, peripheral blood leukocytes showed decreased IL-7Rα expression and IL-7 consumption upon IFNβ exposure, suggesting that their IL-7 responsiveness is impaired during treatment. MS patients undergoing IFNβ treatment have increased serum IL-7 levels and decreased IL-7 consumption. Given IL-7's important role in T-cell immunity, this relationship may be highly relevant for IFNβ's treatment efficacy.

    ABSTRACT: Microglia, a unique type of myeloid cell, play a key role in the inflammation-mediated neurodegeneration occurring during both acute and chronic stages of multiple sclerosis (MS). These highly specialized cells trigger neurotoxic pathways, producing pro-inflammatory cytokines, reactive oxygen and nitrogen species and proteolytic enzymes, causing progressive neurodegeneration. Microglia have also been associated with development of cortical lesions in progressive MS, as well as with alterations of synaptic transmission in experimental autoimmune encephalomyelitis (EAE). However, they also play an important role in the promotion of neuroprotection, downregulation of inflammation, and stimulation of tissue repair. Notably, microglia undergo changes in morphology and function with normal aging, resulting in a decline of their ability to repair central nervous system damage, making axons and neurons more vulnerable with age. Modulation of microglial activation for therapeutic purposes must consider suppressing deleterious effects of these cells, while simultaneously preserving their protective functions.

    ABSTRACT: Patients with multiple sclerosis (MS) lose brain volume (BV) faster than healthy individuals. Our purpose, within the 12-month phase 3 TRANSFORMS study, was to examine the effect of treatment on BV loss in patient subgroups, establish correlations between baseline normalized BV (NBV) and baseline disease parameters, to identify variables predictive of baseline NBV and on-study percentage BV change (PBVC), and to establish correlations between on-study PBVC and on-study efficacy outcomes. Patients received fingolimod 0.5 mg or 1.25 mg, or intramuscular (IM) interferon β-1a (IFNβ-1a) for 12 months. The effect of treatment on PBVC was examined in patient demographic, disease and magnetic resonance imaging (MRI) characteristic subgroups. Pearson's correlation analyses and a stepwise linear regression model were used to identify variables predictive of NBV and PBVC. Fingolimod reduced BV loss over 12 months versus IFNβ-1a IM in all patient subgroups assessed, including individuals with or without gadolinium (Gd)-enhancing lesions at baseline. Baseline T1 hypointense lesion volume had the strongest correlation with baseline NBV. Baseline Gd-enhancing T1 lesion count was most predictive of change in PBVC over 12 months. Our results improve understanding of the contributions of different baseline demographic, clinical and MRI characteristics to NBV, including factors that may be predictive of future BV loss.

    ABSTRACT: The majority of patients with multiple sclerosis (MS) present with spinal cord pathology. Spinal cord atrophy is thought to be a marker of disease severity, but in long-disease duration its relation to brain pathology and clinical disability is largely unknown. Our aim was to investigate mean upper cervical cord area (MUCCA) in patients with long-standing MS and assess its relation to brain magnetic resonance imaging (MRI) measures and clinical disability. MUCCA was measured in 196 MS patients and 55 healthy controls using 3DT1-weighted cervical images obtained at 3T MRI. Clinical disability was measured using the Expanded Disability Status Scale (EDSS), Nine-Hole-Peg test (9-HPT), and 25 feet Timed Walk Test (TWT). Stepwise linear regression was performed to assess the association between MUCCA and MRI measures, and between MUCCA and clinical disability. MUCCA was smaller (mean 11.7%) in MS patients compared with healthy controls (72.56±9.82 and 82.24±7.80 mm(2) respectively; p<0.001), most prominently in male patients. MUCCA was associated with normalized brain volume, and number of cervical cord lesions. MUCCA was independently associated with EDSS, TWT, and 9-HPT. MUCCA was reduced in MS patients compared with healthy controls. It provides a relevant marker for clinical disability in long-standing disease, independent of other MRI measures.

    ABSTRACT: The use of natalizumab has likely been limited by its association with progressive multifocal leukoencephalopathy (PML), an infection caused by the human polyomavirus John Cunningham (JC). Three factors were recently identified that contribute to the overall risk of natalizumab-associated PML: (1) Positive serostatus for anti-JCV antibodies, (2) prior use of immunosuppressants, and (3) duration of natalizumab therapy. This risk stratification algorithm has not led to a reduction in the incidence of PML in natalizumab-treated patients with multiple sclerosis between April 2010 and February 2014. This observation may appear perplexing, as treatment duration and JCV serostatus are modifiable risk factors. Potential reasons for the lack of success of companion diagnostics that determine the overall risk of natalizumab-associated PML are discussed.

    ABSTRACT: Iron accumulation in deep grey matter (GM) structures is a consistent finding in multiple sclerosis (MS) patients. This study focused on the identification of independent determinants of iron accumulation using R2* mapping. Ninety-seven MS patients and 81 healthy controls were included in this multicentre study. R2* mapping was performed on 3T MRI systems. R2*in deep GM was corrected for age and was related to disease duration, disability, T2 lesion load and brain volume. Compared to controls, R2* was increased in all deep GM regions of MS patients except the globus pallidus and the substantia nigra. R2* increase was most pronounced in the progressive stage of the disease and independently predicted by disease duration and disability. Reduced cortical volume was not associated with iron accumulation in the deep GM with the exception of the substantia nigra and the red nucleus. In lesions, R2* was inversely correlated with disease duration and higher total lesion load. Iron accumulation in deep GM of MS patients is most strongly and independently associated with duration and severity of the disease. Additional associations between cortical GM atrophy and deep GM iron accumulation appear to exist in a region specific manner.

    ABSTRACT: Potential differences between primary progressive (PP) and relapsing-remitting (RR) multiple sclerosis (MS) have been controversially discussed. In this study, we compared lesion morphology and distribution in patients with PPMS and RRMS (nine in each group) using 7 T MRI. We found that gray and white matter lesions in PPMS and RRMS patients did not differ in their respective morphological characteristics (e.g. perivascular p = 0.863, hypointense rim p = 0.796, cortical lesion count p = 0.436). Although limited by a small sample size, our study results suggest that PPMS and RRMS, despite differences in disease course and clinical characteristics, exhibit identical lesion morphology under ultrahigh field MRI.

    ABSTRACT: The aim was to analyse risk of relapse phenotype recurrence in multiple sclerosis and to characterise the effect of demographic and clinical features on this phenotype. Information about relapses was collected using MSBase, an international observational registry. Associations between relapse phenotypes and history of similar relapses or patient characteristics were tested with multivariable logistic regression models. Tendency of relapse phenotypes to recur sequentially was assessed with principal component analysis. Among 14,969 eligible patients (89,949 patient-years), 49,279 phenotypically characterised relapses were recorded. Visual and brainstem relapses occurred more frequently in early disease and in younger patients. Sensory relapses were more frequent in early or non-progressive disease. Pyramidal, sphincter and cerebellar relapses were more common in older patients and in progressive disease. Women presented more often with sensory or visual symptoms. Men were more prone to pyramidal, brainstem and cerebellar relapses. Importantly, relapse phenotype was predicted by the phenotypes of previous relapses. (OR = 1.8-5, p = 10(-14)). Sensory, visual and brainstem relapses showed better recovery than other relapse phenotypes. Relapse severity increased and the ability to recover decreased with age or more advanced disease. Relapse phenotype was associated with demographic and clinical characteristics, with phenotypic recurrence significantly more common than expected by chance.

    ABSTRACT: Previous magnetic resonance imaging (MRI) studies have demonstrated increased iron deposition in the basal ganglia of multiple sclerosis (MS) patients. However, it is not clear whether these alterations are associated with changes of iron metabolism in body fluids. The purpose of this study was to investigate if iron metabolism markers in cerebrospinal fluid (CSF) and serum of clinically isolated syndrome (CIS) and MS patients differ from controls and how they relate to clinical and imaging parameters. We analysed serum ferritin, transferrin and soluble transferrin-receptor and CSF ferritin and transferrin by nephelometry in non-anaemic CIS (n=60) or early MS (n=14) patients and 68 controls. In CIS/MS we additionally assessed the T2 lesion load. CSF transferrin was significantly decreased in CIS/MS compared to controls (p<0.001), while no significant differences were seen in serum. Higher CSF transferrin levels correlated with lower physical disability scores (r= -0.3, p<0.05). CSF transferrin levels did not correlate with other clinical data and the T2 lesion load. Our biochemical study provides evidence that altered iron homeostasis within the brain occurs in the very early phases of the disease, and suggests that the transporter protein transferrin may play a role in the increased iron deposition known to occur in the brain of MS patients.

    ABSTRACT: Identification of MS registries and databases that are currently in use in Europe as well as a detailed knowledge of their content and structure is important in order to facilitate comprehensive analysis and comparison of data. National MS registries or databases were identified by literature search, from the results of the MS Barometer 2011 and by asking 33 national MS societies. A standardized questionnaire was developed and sent to the registries' leaders, followed by telephone interviews with them. Twenty registries were identified, with 13 completing the questionnaire and seven being interviewed by telephone. These registries differed widely for objectives, structure, collected data, and for patients and centres included. Despite this heterogeneity, common objectives of the registries were epidemiology (n=10), long-term therapy outcome (n=8), healthcare research (n=9) and support/basis for clinical trials (n=8). While physician-based outcome measures (EDSS) are used in all registries, data from patients' perspectives were only collected in six registries. The detailed information on a large number of national MS registries in Europe is a prerequisite to facilitating harmonized integration of existing data from MS registries and databases, as well as comprehensive analyses and comparison across European populations.

    ABSTRACT: Little information exists about how cognitive impairment in multiple sclerosis (MS) patients impacts on their caregivers' health-related quality of life (HRQoL). The objective of this paper is to examine the extent to which cognitive impairment in MS patients contributes to caregivers' HRQoL. A total of 63 MS patients, 63 caregivers and 59 matched controls were recruited. Patients and controls underwent a neuropsychological assessment, including tests of working memory, speed of information processing, executive function, and verbal fluency. HRQoL of the caregivers was assessed by CAREQOL-MS. In logistic regression models, we adjusted for the effects of confounding variables. In these models, the dependent variable was the CAREQOL-MS (higher median of CAREQOL-MS (worse HRQoL) vs. lower median of CAREQOL-MS (better HRQoL) (reference)), and the independent variable was the impairment on each neuropsychological test vs. its integrity (reference). Cognitive impairment in MS patients was significantly associated with worse caregiver HRQoL (adjusted odds ratio (OR) = 3.10, 95% confidence interval (CI) = 1.07-11.55, p = 0.04). In secondary analyses in which each neuropsychological test was entered in the analyses separately, only Symbol Digit Modalities Test (a measurement of information processing speed) impairment (OR = 4.22, 95%, CI = 1.16-14.53, p = 0.03) was significantly associated with worse caregiver HRQoL. MS patients' caregivers' HRQoL is significantly influenced by information processing speed impairment of MS patients.

    ABSTRACT: auto-antibodies against the potassium channel inward rectifying potassium channel 4.1 (Kir4.1) have previously been identified in 46% of patients with multiple sclerosis (MS). to confirm these findings. we evaluated the presence of anti-Kir4.1 antibodies by enzyme-linked immunosorbent assay (ELISA) and immunofluorescence in 268 MS patients, 46 patients with other neurological diseases (OND) and 45 healthy controls. anti-Kir4.1 antibodies were found in 7.5% of MS patients, 4.3% of OND patients and 4.4% of healthy controls. Immunofluorescence analysis did not identify any specific staining. we confirmed the presence of anti-Kir4.1 antibodies in MS patients, but at a much lower prevalence than previously reported.

    ABSTRACT: Adherence to medical interventions is a global problem. With an increasing amount of partially effective but expensive drug treatments adherence is increasingly relevant in multiple sclerosis (MS). Perceived lack of efficacy and side effects as well as neuropsychiatric factors such as forgetfulness, fatigue and depression are major determinants. However, research on adherence to behavioural interventions as part of rehabilitative interventions has only rarely been studied. In a one-day meeting health researchers as well as patient representatives and other stakeholders discussed adherence issues in MS and developed a general draft research agenda within a focus group session. The focus group addressed four major areas: (1) focussing patients and their informal team; (2) studying health care professionals; (3) comparing practice across cultures; and (4) studying new adherence interventions. A focus on patient preferences as well as a non-judgemental discussion on adherence issues with patients should be at the core of adherence work.
