Selected AbstractsCerebral Atrophy Measurement in Clinically Isolated Syndromes and Relapsing Remitting Multiple Sclerosis: A Comparison of Registration-Based MethodsJOURNAL OF NEUROIMAGING, Issue 1 2007Valerie M. Anderson BSc ABSTRACT Background and Purpose. Brain atrophy is a proposed marker of disease progression in multiple sclerosis (MS). Many magnetic resonance imaging-based methods of atrophy quantification exist, but their relative sensitivity and precision is unclear. Our aim was to compare atrophy rates from the brain boundary shift integral (BBSI), structural image evaluation, using normalization of atrophy (SIENA) (both registration-based methods) and segmented brain volume difference, in patients with clinically isolated syndromes (CIS), relapsing remitting MS (RRMS), and controls. Methods. Thirty-seven CIS patients, 30 with early RRMS and 16 controls had T1-weighted volumetric imaging at baseline and 1 year. Brain atrophy rates were determined using segmented brain volume difference, BBSI, and SIENA. Results. BBSI and SIENA were more precise than subtraction of segmented brain volumes and were more sensitive distinguishing RRMS subjects from controls. A strong correlation was observed between BBSI and SIENA. Atrophy rates were greater in CIS and RRMS subjects than controls (RRMS P < .001). With all methods, significantly greater atrophy rates were observed in CIS patients who developed clinically definite MS relative to subjects who did not. Conclusion. Registration-based techniques are more precise and sensitive than segmentation-based methods in measuring brain atrophy, with BBSI and SIENA providing comparable results. [source] Health-related quality of life in multiple sclerosis: effects of natalizumabANNALS OF NEUROLOGY, Issue 4 2007Richard A. Rudick MD Objective To report the relationship between disease activity and health-related quality of life (HRQoL) in relapsing multiple sclerosis, and the impact of natalizumab. Methods HRQoL data were available from 2,113 multiple sclerosis patients in natalizumab clinical studies. In the Natalizumab Safety and Efficacy in Relapsing Remitting Multiple Sclerosis (AFFIRM) study, patients received natalizumab 300mg (n = 627) or placebo (n = 315); in the Safety and Efficacy of Natalizumab in Combination with Interferon Beta-1a in Patients with Relapsing Remitting Multiple Sclerosis (SENTINEL) study, patients received interferon beta-1a (IFN-,-1a) plus natalizumab 300mg (n = 589), or IFN-,-1a plus placebo (n = 582). The Short Form-36 (SF-36) and a subject global assessment visual analog scale were administered at baseline and weeks 24, 52, and 104. Prespecified analyses included changes from baseline to week 104 in SF-36 and visual analog scale scores. Odds ratios for clinically meaningful improvement or worsening on the SF-36 Physical Component Summary (PCS) and Mental Component Summary were calculated. Results Mean baseline SF-36 scores were significantly less than the general US population and correlated with Expanded Disability Status Scale scores, sustained disability progression, relapse number, and increased volume of brain magnetic resonance imaging lesions. Natalizumab significantly improved SF-36 PCS and Mental Component Summary scores at week 104 in AFFIRM. PCS changes were significantly improved by week 24 and at all subsequent time points. Natalizumab-treated patients in both studies were more likely to experience clinically important improvement and less likely to experience clinically important deterioration on the SF-36 PCS. The visual analog scale also showed significantly improved HRQoL with natalizumab. Interpretation HRQoL was impaired in relapsing multiple sclerosis patients, correlated with severity of disease as measured by neurological ratings or magnetic resonance imaging, and improved significantly with natalizumab. Ann Neurol 2007 [source] Quality of life in 1000 patients with early relapsing,remitting multiple sclerosisEUROPEAN JOURNAL OF NEUROLOGY, Issue 6 2009N. Putzki Background and purpose:, To examine the quality of life (QoL) in a large cohort of untreated patients with relapsing,remitting multiple sclerosis (RRMS) and to investigate the impact of intramuscular (IM) interferon beta-1a (IFNß-1a) treatment. Methods:, Prospective, observational, open-label, multicentre study conducted in Germany. Untreated patients with RRMS who initiated treatment with IM IFNß-1a were included and followed for 12 months. QoL was measured using the EQ-5D questionnaire. Clinical response was assessed by relapse rate and disability (Expanded Disability Status Scale; EDSS). Results:, A total of 1157 patients were included [mean age 37.6 years, median disease duration 13 months, mean relapse rate 1.7 (95%CI: 1.58,1.73), median EDSS score 2.0]. Relapse rate was reduced to 0.6 at 12 months (95%CI: 0.51,0.69, P < 0.0001). EDSS did not change significantly. At baseline, QoL was considerably lower in MS patients compared with the general German population, but was improved after treatment initiation [utilities of EQ-5D: 0.77 (95%CI: 0.75,0.78) vs. 0.75 (95%CI: 0.74,0.76) at baseline, 95%CI for difference: 0.01,0.03, P = 0.0046]. Higher disease activity and inability to work were negative predictors of QoL. 14.7% of patients were incapable of working for MS-related reasons. Conclusions:, Quality of life is considerably impaired in early stages of MS. Treatment initiation with IM IFNß attenuates MS disease activity and improves QoL. Inability to work early during the disease is a major challenge for the social security systems. [source] The effects of natalizumab on inflammatory mediators in multiple sclerosis: prospects for treatment-sensitive biomarkersEUROPEAN JOURNAL OF NEUROLOGY, Issue 4 2009M. Khademi Background:, Natalizumab affects systemic cytokine expressions and clinical course in relapsing,remitting multiple sclerosis (RRMS). We analyzed levels of inflammatory cytokines in cerebrospinal fluid (CSF) cells and peripheral blood mononuclear cells (PBMCs), levels of matrix metalloproteinase (MMP)-9 and osteopontin (OPN) in CSF, and clinical outcome measures in 22 natalizumab-treated RRMS patients. Methods:, mRNA levels of cytokines in cells were detected with real-time RT-PCR. Protein levels of OPN and MMP-9 were measured by ELISA. Results:, Natalizumab reduced CSF cell counts (P < 0.0001). Tumor necrosis factor (TNF) and interferon-, (IFN-,) mRNAs were significantly increased in PBMCs. In contrast, expressions of IFN-, and interleukin (IL)-23 were decreased but IL-10 increased in the CSF cells. OPN and MMP-9 were reduced in the CSF. Patients being in remission at baseline showed the same deviations of mediators as those in relapse after natalizumab treatment. The open label clinical outcome measures were either stable or improved during therapy. Conclusions:, Natalizumab attenuates pro-inflammatory mediators intrathecally and the reduced pro-inflammatory milieu may allow increased production of the anti-inflammatory mediator IL-10. The increased systemic cytokines may impede the improvement of certain clinical measures like fatigue. The affected mediators seem to be sensitive to an immune-modifying treatment which could be used as biomarkers for this therapy. [source] Epstein,Barr virus reactivation and multiple sclerosisEUROPEAN JOURNAL OF NEUROLOGY, Issue 1 2008Ø. Torkildsen Infection with Epstein,Barr virus (EBV) is considered one of the possible key environmental factors in the aetiology of multiple sclerosis (MS). Whether EBV plays an underlying role as an activator of MS remains, however, controversial. Sixty-one patients with definite relapsing,remitting multiple sclerosis (RRMS) according to the Poser criteria were followed for 1 year. Blood samples were drawn at baseline, months 3, 6 and 12, and in case of any clinical exacerbation. Twenty-three baseline,paired exacerbation samples in the same set were quantitatively analysed to examine whether exacerbations in MS were associated with a change in anti-diffuse component of the EBV-early antigen (EA-D) IgG ratio. All the 61 patients (100%) were anti-viral capsid antigen (VCA) IgG positive, one (2%) was anti-VCA IgM positive and 60 (98%) were anti-EBV nuclear antigen IgG positive. Mean anti-EA-D IgG at baseline was 0.57 (range 0.12,2.70) and at the time of exacerbations 0.61 (range 0.11,2.70). Wilcoxon signed rank test revealed no differences between the 23 baseline and paired exacerbation samples (P = 0.58). Our findings suggest that reactivation of latent EBV infection does not play a significant role for exacerbations in RRMS. [source] A longitudinal observational study of a cohort of patients with relapsing,remitting multiple sclerosis treated with glatiramer acetateEUROPEAN JOURNAL OF NEUROLOGY, Issue 11 2007M. Debouverie Immunomodulatory treatments for relapsing,remitting multiple sclerosis (RRMS) are not efficacious or tolerated in all patients. It is important to evaluate alternative classes of treatment in patients failing first-line therapy. The objective of this prospective observational study was to evaluate the efficacy and safety of glatiramer acetate in patients, to whom , -interferons could not be administered. The study included patients with RRMS who were intolerant to or had contraindications to , -interferon. After initiation of glatiramer acetate treatment, follow-up visits were made every 3 months, when data on neurologist-ascertained relapses and disability [Expanded Disability Status Scale (EDSS) score] were collected. Tolerability was evaluated by spontaneous adverse event reporting. Overall, 205 patients were studied and 113 (55.1%) treated for at least 4 years. The proportion of patients presenting over three relapses per year decreased from 51.2% to 8.4% in the 2 years following treatment initiation. Over 5 years of treatment, mean annualized relapse rates and mean EDSS scores remained stable (0.4,0.6 relapses/year and 3.6 ± 1.8,3.3 ± 2.1 respectively). Adverse events were reported by 179 patients, leading to discontinuation of treatment in 10 patients. Patients with RRMS to whom , -interferons cannot be prescribed can benefit from treatment with glatiramer acetate.

[source] Recombinant human interferon beta in relapsing,remitting multiple sclerosis: a review of the major clinical trialsEUROPEAN JOURNAL OF NEUROLOGY, Issue 4 2000M. Chofflon The beneficial effects of interferon beta (IFN-,) on disease activity in relapsing,remitting multiple sclerosis (RRMS) have been confirmed in several clinical trials. Three IFN-, products are currently available and licensed for use in RRMS at different dosages and with different routes of administration. For the prescribing physician, therefore, questions remain about the effect these differences may have on the success of therapy. This paper reviews the four large placebo-controlled clinical trials that have been conducted with IFN-, in patients with RRMS. The evidence available indicates that optimal results are likely to be achieved with the highest tolerable dosage of IFN-,. Furthermore, as inflammatory brain lesions in MS have been shown to exhibit more extensive and early axonal damage than previously suspected, early treatment may be advisable in order to delay disease progression in RRMS. [source] Should neurologists wait and see or see and treat RRMS?PROGRESS IN NEUROLOGY AND PSYCHIATRY, Issue 5 2009David Bates MA Early and aggressive treatment of rheumatoid arthritis (RA) is now regarded as best practice to limit irreversible joint damage. However, in the case of relapsing remitting multiple sclerosis (RRMS), current guidelines recommend that disease modifying therapy should only be initiated in patients with evidence of actively progressing disease. Here, the authors present the key findings of the Programme Identifying and Observing Novel Therapy Adoption in Chronic Diseases (PIONEER) study to examine the reasons for these different management approaches. Copyright © 2009 Wiley Interface Ltd [source] Quality of life in multiple sclerosis: a Kuwaiti MSQOL-54 experienceACTA NEUROLOGICA SCANDINAVICA, Issue 6 2008A. F. Alshubaili Objectives,,, We compared the quality of life (QOL) self-ratings of relapsing,remitting multiple sclerosis (RRMS) and progressive multiple sclerosis (PMS) patients with those of the general population; and assessed the association of demographic, clinical, and caregiver variables with patients' QOL. Methods,,, Consecutive clinic attendees were assessed with MSQOL-54, Beck's Depression Inventory, and Expanded Disability Status Scale. Caregivers rated their impression of patients' QOL and attitudes to patients' illness. Results,,, Of 170 patients (35.5% M, 64.5% F), 85.3% had RRMS and 14.7% PMS. RRMS had higher QOL domain scores (P < 0.001). Patients had lower QOL than controls (P < 0.001). Depression was the commonest significant covariate of QOL domains. After controlling for depression and disability, differences between the MS groups were less significant. Predictors of overall QOL were caregiver impression of patient's QOL, depression, and treatment side effects. Conclusion,,, Programs that address depression, disability, the impact of treatment side effects, caregiver attitudes and education should enhance QOL outcomes. [source] Interferon- ,1b treatment modulates cytokines in patients with primary progressive multiple sclerosisACTA NEUROLOGICA SCANDINAVICA, Issue 6 2006A. Dressel Objectives,,, It is unknown whether the immunological effects of , -interferon (IFN- ,) differ in primary progressive multiple sclerosis (PPMS) when compared with relapsing,remitting multiple sclerosis (RRMS). Therefore, we investigated the effects of IFN- ,1b treatment in PPMS on proliferation and cytokine pattern of peripheral blood mononuclear cells (PBMC) and interleukin-10 (IL-10) serum level. Methods,,, Eighteen patients were treated with IFN- ,1b for 12 months in an open-label trial. Serum and PBMC were collected longitudinally. Results,,, Interleukin-10 serum levels increased (P = 0.02) during treatment. Tumor necrosis factor- , was increased in anti CD3 (OKT3) antibody stimulated PBMC during treatment (P = 0.04), whereas secretion of IL-10 was decreased in OKT3 (P = 0.04), but increased in concavalin A stimulated PBMC (P = 0.02). Conclusions,,, Interleukin-10 serum levels rose in IFN- ,1b-treated patients as has been observed in RRMS. The changes in cytokine patterns secreted by T-lymphocytes of PPMS patients, however, differ from effects observed in RRMS supporting the hypothesis that PPMS differs in some immunological aspects from RRMS. [source] Interferon beta-1b treatment in patients with relapsing,remitting multiple sclerosis under a standardized protocol in SpainACTA NEUROLOGICA SCANDINAVICA, Issue 4 2000T. Arbizu Objective, A protocol system is being used in Spain for the prescription of innovative drugs including interferon beta-1b (IFN,-1b). Petitions for dispensing and reimbursement are based on the inclusion and exclusion criteria of pivotal trials, and are reviewed individually for approval by specialist committees. To estimate the performance of IFN,-1b in the clinical setting, data collected by the INSALUD and regional health services of Andalusia and Catalonia, together responsible for the healthcare of nearly 30 million individuals, were compiled in a common database for analysis. Methods, Data comprise demographic and disease characteristics at the time of petition and at follow-up 3 months after treatment initiation and every 6 months thereafter. Efficacy was estimated by mean number of relapses per year, proportion of relapse-free patients, and disease progression as measured by the Expanded Disability Status Scale (EDSS). Safety parameters included adverse events and laboratory analyses. Results, Between September 1995 and database cutoff in mid-1998, petitions of 1419 patients were approved for IFN,-1b treatment. Patients were homogenous across the three databases and in the subgroups of patients completing 1 year (n=940) and 2 years (n=302) of treatment. There was a marked decrease in the mean number of relapses in the first 12 months of IFN,-1b treatment for the 938 patients documented for 12 months, with a mean of 0.4 (±0.7 SD) relapses per patient and year, and a 2-year mean of 0.9 (±1.20 SD) in the 302 patients documented for 24 months. Of the 938 patients followed for ,12 months, 505 (53.8%) were documented as being relapse-free during 12 months of treatment, and 146 (48.3%) of the 302 patients followed for ,24 months, were relapse-free during 24 months of treatment. There were no differences in mean or median EDSS scores between baseline and months 12 and 24. Skin disorders were the most frequent adverse events, reported in over one-third of all patients; there were 159 injection site events, most frequently erythema (115 events). Systemic AEs pointing towards flu-like symptoms were reported in 288 of 1419 patients (20.3%). Leukopenia was the most frequently reported laboratory event. Elevations in liver transaminases were noted for 12 patients (0.8%) with SGOT increase and 7 (0.5%) with SGPT increase. Conclusion, The protocol system has helped make IFN, treatment available to 8,10% of the estimated 15,000,18,000 MS patients in the regions studied. In terms of efficacy, IFN,-1b performed in line with the pivotal study results. The safety profile of IFN,-1b was consistent with the published findings and the drug labelling, and no new side effects or increased incidence of known side effects was observed. [source] |
