Background: With the advent of MRI scanning, the value of lumbar puncture to assess oligoclonal band (OCB) statusfor the diagnosis of multiple sclerosis (MS) is increasingly uncertain. One major issue is that the reported frequency of cerebrospinal fluid (CSF)-restricted oligoclonal banding for the diagnosis of MS varies considerably in different studies. In addition, the relationship between OCB positivity and disease outcome remains uncertain, as reported studies are generally too small to assess comparative disability outcomes with sufficient power. Methods: In order to further investigate variation of OCB positivity in patients with MS, we utilized MSBase, a longitudinal, Web-based collaborative MS outcomes registry following clinical cohorts in several continents and latitudes. We also assessed whether OCB positivity affects long-term disability outcome. Results: A total of 13,242 patient records were obtained from 37 MS specialist centres in 19 different countries. OCB status was documented in 4481 (34%) patients and 80% of these were OCB positive. The presence of OCB was associated with degree of latitude ( p = 0.02). Furthermore, the outcome of patients negative for CSF-specific OCB was significantly better in comparison to the OCB positive patients, as assessed by Expanded Disability Status Scale change ( p < 0.001). Conclusions: The results of this study indicate that latitude could explain some of the inconsistencies in OCB status reported in different populations. The study confirms that OCB positivity in MS is associated with a worse long-term prognosis.

Background: Prognostic counselling is a sensitive issue in medicine and especially so in MS due to the highly heterogeneous disease course. However, people with MS (pwMS) seek prognostic information. The web-based ‘Evidence-Based Decision Support Tool in Multiple Sclerosis’ (EBDiMS) uses data of 717 patients from the London/Ontario cohort to calculate personalized long-term prognostic information. Objective: The aim of this study was to investigate the feasibility and effect of long-term prognostic counselling in pwMS using EBDiMS. Methods: Ninety consecutive pwMS were provided with personalized estimations of expected time to reach Expanded Disability Status Scale (EDSS) scores of 6 and 8 and time to conversion to secondary-progressive MS. Participants gave estimates on their own putative prognosis and rated the tool’s acceptability on six-step Likert-type scales. Results: Participants rated EBDiMS as highly understandable, interesting and relevant for patient–physician encounters, coping and therapy decisions. Although it provoked a certain degree of worry in some participants, 95% would recommend using the tool. Participants’ own prognosis estimates did not change significantly following EBDiMS. Conclusion: Long-term prognostic counselling using an online tool has been shown to be feasible in a clinical setting. EBDiMS provides pwMS with relevant, easy-to-understand, long-term prognostic information without causing relevant anxiety.

Objective: To describe the spatial relationship between relapse and disability in multiple sclerosis (MS). Methods: 141 relapse onset MS patients were studied. For each patient an examination was performed and a relapse history obtained. Multivariate logistic regression examined whether there was an association between localizing clinical signs and a history of relevant relapse in order to explore the spatial relationship between relapse and subsequent disability. Results: The presence of impaired vision or sensation was independently associated with a history of one or more anatomically related relapses. The presence of weakness or cerebellar ataxia in a limb was not associated with a single relevant relapse but was associated with multiple relevant relapses. A history of multiple episodes of weakness or ataxia in the same limb was uncommon. Conclusions: Our data suggest that motor pathways are relatively resistant to chronic impairment from acute relapse, whereas afferent pathways are more susceptible. This, in combination with prominent usage of the Expanded Disability Status Scale, which is dependent on mobility and motor function at higher scores, may explain the paradox between natural history studies that suggest relapses are irrelevant to long-term disability and shorter studies at lower disability levels suggesting relapses are responsible for disability accumulation.

Objective Large demyelinating lesions with possible mass effect (tumefactive multiple sclerosis or tumefactive demyelination) can be mistaken for tumour-like space-occupying lesions suggesting a malignant outcome. Methods We reviewed our own experience of multiple sclerosis subjects ( n = 28) with tumefactive demyelination to determine the relationship between clinical outcomes and lesion evolution, clinical outcomes and their relationship to different therapies. Patients with central nervous system demyelinating disease were identified from our database over the last 10 years. Results No patient increased in extended disability status scale (EDSS). Overall, lesion regression was associated with improved EDSS. Lesion regression was also associated with therapy versus no therapy. No specific therapy or corticosteroid infusions improved EDSS over the long term. The absence of enhancement on follow up on magnetic resonance imaging portended lesion regression. Conclusion Tumefactive demyelination may predict a more benign overall course and is susceptible to traditional immunomodulatory treatments.

Background: Benign multiple sclerosis (BMS) is a controversial concept which is still debated. However identification of this kind of patients is crucial to prevent them from unnecessary exposure to aggressive and/or long term medical treatments. Objectives: To assess two definitions of ‘clinically definite benign multiple sclerosis’ (CDBMS) using long-term follow-up data, and to look for prognostic factors of CDBMS. Methods: In 874 patients with definite relapsing–remitting MS, followed up for at least 10 years, disability was assessed using the Disability Status Scale (DSS). CDBMS was defined by either DSS score≤2 (CDBMS1 group) or DSS score≤ 3 (CDBMS2 group) at 10 years. We estimated the proportion of patients who were still benign at 20 and 30 years after clinical onset. Results: CDBMS frequency estimates were 57.7% and 73.9% when using CDBMS1 and CDBMS2 definitions, respectively. In the CDBMS1 group, only 41.7% (105/252) of cases were still benign 10 years later, and 41.1% (23/56) after an additional decade, while there were 53.8% (162/301) and 59.5% (44/74) respectively in the CDBMS2 group. Conclusions: This 30-year observational study, which is one of the largest published series, indicates that favourable 10-year disability scores of DSS 2 or 3 fail to ensure a long-term benign course of multiple sclerosis. After every decade almost half of the CDBMS were no longer benign. CDBMS, as currently defined, is an unwarranted conceptual hodgepodge. Other criteria using new biomarkers (genetic, biologic or MRI) should be found to detect benign cases of MS.

Background: The development of predictors of multiple sclerosis (MS) disability is difficult due to the complex interplay of pathophysiological and adaptive processes. Objective: The purpose of this study was to investigate whether combined evoked potential (EP)-measures allow prediction of MS disability after 20 years. Methods: We examined 28 patients with clinically definite MS according to Poser’s criteria with Expanded Disability Status Scale (EDSS) scores, combined visual and motor EPs at entry (T0), 6 (T1), 12 (T2) and 24 (T3) months, and a cranial magnetic resonance imaging (MRI) scan at T0 and T2. EDSS testing was repeated at year 14 (T4) and year 20 (T5). Spearman rank correlation was used. We performed a multivariable regression analysis to examine predictive relationships of the sum of z-transformed EP latencies ( s-EPT0) and other baseline variables with EDSST5. Results: We found that s-EPT0 correlated with EDSST5 (rho=0.72, p<0.0001) and ΔEDSST5-T0 (rho=0.50, p=0.006). Backward selection resulted in the prediction model: E (EDSST5)=3.91–2.22×therapy+0.079×age+0.057× s-EPT0 (Model 1, R2=0.58) with therapy as binary variable (1=any disease-modifying therapy between T3 and T5, 0=no therapy). Neither EDSST0 nor T2-lesion or gadolinium (Gd)-enhancing lesion quantities at T0 improved prediction of EDSST5. The area under the receiver operating characteristic (ROC) curve was 0.89 for model 1. Conclusions: These results further support a role for combined EP-measures as predictors of long-term disability in MS.

Cladribine is currently registered as a 10-milligram tablet formulation with a fixed cumulative dosage of 3.5 mg/kg over 2 years. It is important to investigate if an increased dosage may lead to further clinical stability with preserved safety. This study used an off-label subcutaneous (s.c.) formulation of cladribine and compared outcomes (Expanded Disability Status Scale (EDSS) scores and disease progression) between 52 relapsing multiple sclerosis (RMS) patients receiving different s.c. dosing regimens with up to 20 years of follow-up. The study group received induction therapy with s.c. cladribine (1.8 mg/kg cumulative dose; consistent with 3.5 mg/kg of cladribine tablets). Patients were subsequently offered maintenance therapy (repeated courses of 0.3 mg/kg s.c. cladribine during 5–20-year follow-up). Forty-one patients received an increased cumulative dose (higher than the induction dose of 1.8 mg/kg); 11 received the standard induction dose. Risk of progression on the EDSS correlated with lower cumulative dose (p < 0.05) and more advanced disability at treatment initiation (p < 0.05) as assessed by EDSS change between year 1 and years 5 and 10 as the last follow-up. Maintenance treatment was safe and well-tolerated, based on limited source data. Subcutaneous cladribine with increased cumulative maintenance dosage was associated with disease stability and favorable safety over a prolonged period of follow-up (up to 20 years) in RMS patients.

This chapter demonstrates the importance of a well-formulated and articulated information security policy by integrating best practices with a case analysis of a major Japanese multinational automotive manufacturer and the security lessons it learned in the implementation of its Web-based portal. The relationship between information security and business needs and the conflict that often results between the two are highlighted. The case also explores the complexities of balancing business expedience with long-term strategic technical architecture. The chapter provides insight and offers practical tools for effectively developing and implementing information security policies and procedures in contemporary business practice.

Background: The association between cognitive impairment and physical disability was examined in a larger, more representative sample of patients with multiple sclerosis (MS) than in previous studies. Method: Two hundred and fifty-three patients attending an MS clinic were assessed with respect to physical disability using the Expanded Disability Status Scale and cognitive impairment using a battery of neuropsychological tests. Results: Physical disability correlated with duration of disease; cognitive impairment did not. Virtually all measures derived from the cognitive battery were significantly correlated with physical disability. Three measures of speeded information processing and one involving delayed recall of verbal material were unique predictors of disability status. The relationship between cognitive impairment and physical disability was equivalent for patients with shorter (<3 years) versus longer (>10 years) disease duration. Cognitive impairment correlated with the rate of disability progression as reflected by the progression index. Conclusion: Cognitive impairment is more closely associated with physical disability than most previous studies indicate. This relationship appears to be stable throughout the duration of MS, although this conclusion is qualified by the cross-sectional design of the study. Further attention should be paid to cognitive impairment as a possible predictor of the rate of patients’ physical decline.

To evaluate the safety and efficacy of long-term glatiramer acetate (GA) therapy, 46 patients with relapsing—remitting multiple sclerosis (RRMS) were treated for up to 22 years in an ongoing, open-label study. Kurtzke expanded disability status scale (EDSS) was measured every six months, relapses were reported at occurrence and patients self-reported adverse events (AEs). At GA initiation, disease durations ranged from 0—20 years (median 6.0 years) and at data cut-off (October 2004), GA therapy duration ranged from 1—22 years (median 12.0 years). Mean EDSS score increased 0.9 ± 1.9 from the pretreatment score (3.0 ± 1.8; P = 0.076). Only 10/28 (36%) patients with baseline EDSS <4.0 had a last observed value ≥ 4.0 and 8/34 (24%) with entry EDSS < 6.0 reached EDSS ≥ 6.0. A majority (57%) maintained improved or unchanged EDSS scores. Annualized relapse rate decreased to 0.1 ± 0.2 from 2.9 ± 1.4 prestudy ( P < 0.0001). Of the 18 remaining patients in October 2004 (average disease duration 23 years), 17% with baseline EDSS scores < 4.0 reached EDSS ≥ 4.0 and 28% with baseline scores < 6.0 reached EDSS ≥ 6.0. Adverse events were similar to those reported in short-term clinical trials. This study shows a low rate of relapses and EDSS progression in RRMS patients on GA for up to 22 years.
