Predictors of successful acceptance of home telemanagement in veterans with Multiple Sclerosis.
Results confirm a favourable effect on relapses as pregnancy proceeds, and an early postpartum peak. Pre-conception DMT exposure and low ARR were independently protective against postpartum relapse. This novel finding could provide clinicians with a strategy to minimise postpartum relapse risk in women with MS planning pregnancy.


Younger age, female sex, and high number of awakenings and arousals are predictive of fatigue in sleep-disordered patients. Further investigations are needed to find the pathophysiological explanation for these relationships.

Copaxone (Glatiramer acetate) treatment effects on gene expression in monocytes of multiple sclerosis patients.
Overall, the observed gene regulatory effects of GA on monocytes were modest and not stable over time. However, our study revealed several genes that are worthy of investigation in future studies on the molecular mechanisms of GA therapy.

Treatment patterns in disease-modifying therapy for patients with multiple sclerosis in the United States.
Most MS patients initiating DMT started on platform therapy. Natalizumab initiators tended to stay on index therapy, have fewer treatment gaps, and switch less than platform initiators in the 2 years after treatment initiation. Switching between platform therapies is common despite evidence that MS patients on platform therapy may benefit from switching to natalizumab.

[Cavitary lesions in multiple sclerosis: Multicenter study on twenty patients.]
MS patients with large cavitary lesions seem to represent a MS subgroup, predominantly women, with relatively late disease onset, predominantly primary-progressive type, relatively high EDSS scores, and severe cognitive dysfunction.

Safety and efficacy of mitoxantrone in pediatric patients with aggressive multiple sclerosis.
Our results suggest MX is a good candidate for treatment of children with worsening RRMS and SPMS. Recommendations regarding patient selection, treatment administration, and close follow-up should be considered. Continuing research is needed to establish its efficacy and safety profile in a multinational collaboration with careful follow-up of adverse events.



The demographic characteristics of the White MS patients in our cohort are very similar to those recently described in another UK-based geographically-linked MS cohort of 620 patients in Wales which was 97% White (J Neurol, Neurosurg & Psychiatry 80 (4):386-391). They described a mean age of 51, a female:male ratio of 2.4:1, and a prevalence of 146 per 100,000. However, what is unique to our cohort is its ethnic diversity, allowing us to show prevalences for ethnic minorities. What is more, when data coding is complete, we will be able to conduct further epidemiological studies, including migration studies, treatment effectiveness studies, and case-control studies of risk factors.


Multiple Sclerosis (MS) is a complex neurological disorder most likely caused by gene-environment interactions. There is a latitudinal gradient of MS prevalence and vitamin D deficiency has been strongly implicated in MS aetiology. Iran is a country of high levels of sunshine which has previously been considered a low-risk MS region. However, Iran has recently observed an 8.3-fold rise in the incidence of MS between 1989-2006.


There was a high frequency of both low BMD and Vitamin D deficiency in this cohort of relatively young and largely ambulatory patients with an acute relapse. Current tools, such as the WHO FRAX algorithm, are inadequate in assessing bone status and fracture risk in this patient group, predominantly as they are focused on older age groups. We present a simple clinical management algorithm.
 
Our study provides a comprehensive picture of the prevalence and incidence of MS throughout the UK. We estimate that 126,669 people were living with MS in the UK in 2010 (2,034 pm population), and that 6,003 new cases were diagnosed that year (96.4 pm/yr). There is an increasing population living longer with MS, which has important implications for resource allocation for MS in the UK.

Comparative effectiveness of GILENYA (fingolimod) versus interferons or glatiramer acetate for relapse rates in multiple sclerosis: a retrospective US claims database analysis.
Results: The study enrolled 525 patients (fingolimod, n = 128; combined IFN/GA cohort, n = 397) of the 31,041 initially identified. Similar findings for fingolimod and IFN/GA were observed for the unadjusted proportion of patients experiencing relapses (31.3% vs. 34.0%, respectively; p = 0.5653) and ARRs (0.50 vs. 0.55, respectively) while persistent to treatment. After adjusting for baseline differences, fingolimod was associated with a 52% reduction in the probability of having a relapse (odds ratio, 0.48; 95% confidence interval [CI], 0.28-0.84; p = 0.0097) and a 50% reduction in ARR (rate ratio, 0.50; 95% CI, 0.34-0.75; p = 0.0006) compared with IFN/GA.

267 Occupation and Multiple Sclerosis: an Italian case-control study
Our preliminary findings indicate that solvent exposures could be related to the risk of MS, as both shoe/leather workers and mechanical manufacturing industry workers are exposed to organic solvents. Interestingly, a major risk of MS was also found among workers engaged in agriculture, suggesting a role of pesticides, whose neurotoxic effect is well known.

Dalfampridine improves walking speed, walking endurance, and community participation in veterans with multiple sclerosis: a longitudinal cohort study 
Dalfampridine-ER was associated with short-term improvements in walking speed and community participation, and sustained improvements in walking endurance and self-perceived impact of MS on walking for one year. Our study supports the utility of this medication in late MS.  

Disease modification in multiple sclerosis: an update
Oligoclonal bands and age at onset correlate with genetic risk score in multiple sclerosis 
The MSGB score was associated with specific clinical MS characteristics, such as OCBs and AAO. This study underlines the need for well-characterized, large cohorts of MS patients, and the usefulness of summarizing multiple genetic risk factors of modest effect size in genotype-phenotype analyses.  

Childhood obesity and risk of pediatric multiple sclerosis and clinically isolated syndrome
Characterising aggressive multiple sclerosis
AMS was identified in 4–14% of patients, depending on the definition used. Although there was a relative preponderance of men and primary progressive MS presenting with AMS, the majority of patients were still women and those with relapsing-onset MS.  

Evidence-based patient information programme in early multiple sclerosis: a randomised controlled trial
The intervention significantly increased informed choice and relevant risk knowledge without negative side effects.  

A SERVICE DEVELOPMENT AUDIT OF FAMPRIDINE (AMPYRA) USE IN MS.
The 2MWT and accelerometry are good objective measures of walking disability in addition to the T25FW. Accelerometry provides additional real-life data regarding activity during the day, and offers information regarding the impact of fatigue on a patient. The MSWS-12 subjectively measures impact of walking disability and the ABC score predicts falls. The use of an assistive device identifies walking disability and predicts risk of falls. Given the uncertainty regarding falls risk in patients using fampridine, physicians should consider using these tools to monitor patients under consideration for the drug.

Significant increases in sodium were seen in lesions and normal appearing brain tissues in MS. Increased concentration of sodium in lesions, cortical grey matter, NAWM and basal ganglia in SPMS versus RRMS indicates greater neuroaxonal metabolic dysfunction and/or loss in the former group. MRI measurement of sodium concentration in vivo is likely to reflect clinically relevant neuroaxonal pathophysiology and may be a useful outcome measure in trials of putative neuroprotective treatments.

LATE–ONSET MULTIPLE SCLEROSIS IN SOUTH–EAST WALES

A DECADE OF DATA FOR THE UK MULTIPLE SCLEROSIS RISK–SHARING SCHEME

USING ROUTINE POINT–OF–CARE DATA FOR RESEARCH: THE EAST LONDON MULTIPLE SCLEROSIS COHORT
The demographic characteristics of the White MS patients in our cohort are very similar to those recently described in another UK–based geographically–linked MS cohort of 620 patients in Wales which was 97% White (J Neurol, Neurosurg & Psychiatry 80 (4):386–391). They described a mean age of 51, a female:male ratio of 2.4:1, and a prevalence of 146 per 100,000.

Predictors and dynamics of postpartum relapses in women with multiple sclerosis
Results confirm a favourable effect on relapses as pregnancy proceeds, and an early postpartum peak. Pre-conception DMT exposure and low ARR were independently protective against postpartum relapse. This novel finding could provide clinicians with a strategy to minimise postpartum relapse risk in women with MS planning pregnancy.

NEUTRALISING ANTIBODIES TO INTERFERON–BETA PREDICT CONVERSION TO SECONDARY PROGRESSIVE MULTIPLE SCLEROSIS IN PATIENTS WITH MULTIPLE SCLEROSIS 
This study demonstrates a significantly increased risk of progression from RRMS to SPMS in patients who become NAb positive. As no current disease modifying treatments are effective in this phase of the disease patients at risk should be detected early and routine NAb testing can help to inform this decision.

A bird's-eye view of T cells during TYSABRI (natalizumab) therapy

Epstein-Barr virus in oral shedding of children with multiple sclerosis
Children with MS demonstrate abnormally increased rates of EBV viral reactivation and a broader range of genetic variants, suggesting a selective impairment in their immunologic control of EBV.  

Natalizumab affects the T-cell receptor repertoire in patients with multiple sclerosis
Profound TCR repertoire restrictions in CSF of patients treated with natalizumab reflect an altered immune surveillance of the CNS, which may contribute to an increased risk of developing PML. Natalizumab seems to prompt an impaired or delayed peripheral expansion of antigen-specific T cells, whereas increased reconstitution of peripheral T-cell expansion following plasma exchange may trigger PML-IRIS. Our data suggest that treatment with natalizumab results in broader changes in the T-cell immune repertoire beyond lymphocyte migration.

CHANGING FACE OF MULTIPLE SCLEROSIS IN THE UNITED KINGDOM 1990-2010. AN INCIDENCE AND PREVALENCE STUDY.

Presentation of MS in older adults is often atypical, with sensorimotor and cerebellar symptoms constituting the predominant clinical syndrome, negative investigations including OCBs, fewer relapses and earlier progression of disability. This may make diagnosis of LOMS problematic. Once LOMS is established, disability progresses more rapidly than in younger onset patients. Although at present there are no effective treatments for progressive neurodegeneration in MS, it is important to identify this group of patients who are likely to require greater input from MS services, and who may benefit from early treatments for progression of disease in the future.

Autologous MSCs can be safely administered in secondary progressive MS with evidence to suggest structural, functional and physiological improvement following treatment consistent with neuroprotection. The transient treatment response seen implied a likely requirement for repeat infusions to sustain benefit in the long-term.

White cell pleocytosis was the most frequent abnormality (48%) followed by raised CSF protein (54%) and positive OCBs (41%) and were most commonly observed within 30 days of relapse. Cell counts of >50/ml and CSF protein of >1.0 g/dl, contrary to popular belief, were unusual. In addition CSF changes in NMO were frequently dynamic and likely to relate to recent disease activity. Whilst these changes may be useful in monitoring some aspects of disease activity OCBs should not be employed to discriminate between NMO and other neuroinflammatory disorders and in particular MS, and also challenge the concept that development of positive OCB status is irreversible.

Application of the Oxford 2012 diagnostic criteria in a clinical setting resulted in an 85% specificity for differentiating NMO from RRMS, the most common differential diagnosis compared to only 67% for Barkhof's criteria. This data should be considered in the MRI assessment of patients in whom the diagnosis of NMO is being considered. In particular patients fulfilling Barkhof's criteria should also be assessed with the Oxford 2012 criteria to improve the interpretation of brain MR imaging and its diagnostic accuracy.

There was a high frequency of both low BMD and Vitamin D deficiency in this cohort of relatively young and largely ambulatory patients with an acute relapse. Current tools, such as the WHO FRAX algorithm, are inadequate in assessing bone status and fracture risk in this patient group, predominantly as they are focused on older age groups. We present a simple clinical management algorithm.


Our data indicate significant variation in practice amongst Scottish neurologists regarding the diagnosis of MS. It seems that few are enthusiastic about applying the current diagnostic criteria after a single attack (CIS), even if the diagnostic criteria are met. Case mix, clinical expertise and experience may explain some of this variation, and given the lack of evidence for aggressive treatment of CIS, such diagnostic caution is perhaps justified. It would be of interest to repeat the audit UK wide, and internationally, and our prediction would be that some countries may embrace the criteria with more enthusiasm than others. This will inevitably affect future epidemiological and therapeutic studies.


Using PSIR at 3T, lesions involving CGM were visible in all lobes. A higher number of CGM lesions were noted in the frontal and temporal lobes both relapsing remitting and progressive MS subgroups. Occipital CGM lesions were uncommon.


MULTIPLE SCLEROSIS AND THE IRANIAN REVOLUTION.


In this interim analysis of UK TOP results, patients treated with natalizumab had significantly improved ARRs, regardless of baseline treatment or relapse history. EDSS scores remained stable over time. Safety data were consistent with natalizumab's known safety profile. Analyses of UK TOP data over longer periods of time will further characterise the effect of natalizumab on disability, as well as on other long-term efficacy and safety parameters in a real-world setting.

Younger age, female sex, and high number of awakenings and arousals are predictive of fatigue in sleep-disordered patients. Further investigations are needed to find the pathophysiological explanation for these relationships.

The dimeric Tβ4 exhibited enhanced activity on wound healing than native Tβ4, and the purification process was simple and cost-effective. This data could be of significant benefit for the high pain and morbidity associated with chronic wounds disease. A better strategy to develop Tβ4 as a treatment for other diseases caused by injuries such as heart attack, neurotrophic keratitis, and multiple sclerosis was also described.

Internet-based FS and EDSS show good agreement with physician-measured scores. Agreement was better in patients with higher scores, indicating that internet-based assessment may be useful for patients with greater disability. Interestingly, >90% patients self-scored higher in the bowel/bladder FS than the physician-rated scores, highlighting that a web-based assessment may be useful for patient who have difficulty describing personal symptoms. Overall patient satisfaction with the web-based assessment was high. An internet-based assessment tool is likely to prove an invaluable tool in the long-term monitoring in MS; not least for those patients who have difficulty travelling to see physicians regularly due to the severity of their disease.





This study demonstrates the validity of the risk score generated, which integrates genetic and environmental risk factors. Siblings have a risk score intermediate to PwMS and HC, confirming their "at risk" position in the endophenotype construct. Much of the MS risk in siblings can be attributed to genetics, with environmental factors potentially providing the trigger for clinically apparent disease.

Our study begins to explore possible epistatic effects between genes in MS employing extremes of outcome, which increases power and may be able to detect effects that conventional models are underpowered for. Our findings suggest that interactions between antigen presenting cell activation and other components of the inflammatory cascade predispose patients to early-onset disease, and indicate a possible role for KIF21B in the onset of disease progression. We have set out a methodology for exploration of epistatic effects on MS phenotype which requires confirmation in replication studies.

The BRAIN test is a widely-available, objective test of upper limb motor function in neurological disease and can be use in the outpatient clinic, home and in clinical trials. Tapping speed is reduced in MS patients when compared to healthy controls and by a similar extent to that seen in PD. MS patients do not have prolonged dwell time when pressing keys, which is a feature of the PD patient group and perhaps extra-pyramidal slowing. This potential for the BRAIN test in differentiating pyramidal from extra-pyramidal motor dysfunction requires further study.

Assuming that reduced GM MTR implies demyelination and atrophy reflects neuronal loss, the results suggest that: (i) in progressive (SP and PP) MS there is overall more extensive GM demyelination than neuronal loss; (ii) in RRMS there is overall more extensive GM neuronal loss with less noticeable demyelination, (iii) cortical demyelination occurs in more regions in SPMS and PPMS than RRMS; (iv) demyelination and neuronal loss often occur in different locations in the cortex, and (v) co-existent demyelination and neuronal loss is most evident in the thalamus. The variation in regional abnormalities argue against a single common mechanism for demyelination and neuronal loss in MS GM.

This study demonstrates a significantly increased risk of progression from RRMS to SPMS in patients who become NAb positive. As no current disease modifying treatments are effective in this phase of the disease patients at risk should be detected early and routine NAb testing can help to inform this decision.

In addition to a prominent global influence on cognitive performance, patients with progressive MS commonly exhibit independent language and visuospatial deficits. Evaluation of these abilities should therefore be included in clinical assessment of cognition in progressive MS. The underrepresentation of frontal-executive dysfunction also seen in our study raises the possibility that language and visuospatial deficits may be characteristic of cognitive impairment in progressive MS.

The demographic characteristics of the White MS patients in our cohort are very similar to those recently described in another UK-based geographically-linked MS cohort of 620 patients in Wales which was 97% White (J Neurol, Neurosurg & Psychiatry 80 (4):386-391). They described a mean age of 51, a female:male ratio of 2.4:1, and a prevalence of 146 per 100,000. However, what is unique to our cohort is its ethnic diversity, allowing us to show prevalences for ethnic minorities. What is more, when data coding is complete, we will be able to conduct further epidemiological studies, including migration studies, treatment effectiveness studies, and case-control studies of risk factors.
