EFNS guideline on treatment of multiple sclerosis relapses: report of an EFNS task force on treatment of multiple sclerosis relapses

EUROPEAN JOURNAL OF NEUROLOGY, Issue 12 2005
F. Sellebjerg
Relapses, exacerbations or attacks of multiple sclerosis are the dominating feature of relapsing-remitting multiple sclerosis (MS), but are also observed in patients with secondary progressive MS. High-dose methylprednisolone is the routine therapy for relapses at present, but other treatments are also in current use. The objective of the task force was to review the literature on treatment of MS relapses to provide evidence-based treatment recommendations. Review was carried out on the literature with classification of evidence according to the EFNS guidelines for scientific task forces. Short-term, high-dose methylprednisolone treatment should be considered for the treatment of relapses of MS (level A recommendation). The optimal glucocorticoid treatment regimen, in terms of clinical efficacy and adverse events, remains to be established. A more intense, interdisciplinary rehabilitation programme should be considered as this probably further improves recovery after treatment with methylprednisolone (level B recommendation). Plasma exchange is probably efficacious in a subgroup of patients with severe relapses not responding to methylprednisolone therapy, and should be considered in this patient subgroup (level B recommendation). There is a need for further randomized, controlled trials in order to establish the optimal treatment regimen for relapses of MS. [source]


A Magnetization Transfer MRI Study of Deep Gray Matter Involvement in Multiple Sclerosis

Jitendra Sharma MD
ABSTRACT Background/Purpose: Gray matter involvement in multiple sclerosis (MS) is of growing interest with respect to disease pathogenesis. Magnetization transfer imaging (MTI), an advanced MRI technique, is sensitive to disease in normal appearing white matter (NAWM) in patients with MS. Design/Methods: We tested if MTI detected subcortical (deep) gray matter abnormalities in patients with MS (n= 60) vs. age-matched normal controls (NL, n= 20). Magnetization transfer ratio (MTR) maps were produced from axial proton density, conventional spin-echo, 5 mm gapless slices covering the whole brain. Region-of-interest,derived MTR histograms for the caudate, putamen, globus pallidus, thalamus, and NAWM were obtained. Whole brain MTR was also measured. Results: Mean whole brain MTR and the peak position of the NAWM MTR histogram were lower in patients with MS than NL (P < .001) and mean whole brain MTR was lower in secondary progressive (SP, n= 10) than relapsing-remitting (RR, n= 50, P < .001) patients. However, none of the subcortical gray matter nuclei showed MTR differences in MS vs. NL, RR vs. SP, or SP vs. NL. Conclusions: The MTI technique used in this cohort was relatively insensitive to disease in the deep gray matter nuclei despite showing sensitivity for whole brain disease in MS. It remains to be determined if other MRI techniques are more sensitive than MTI for detecting pathology in these areas. [source]


A 3-year magnetic resonance imaging study of cortical lesions in relapse-onset multiple sclerosis

Massimiliano Calabrese MD
Objective We assessed the occurrence, extent, and frequency of formation of cortical lesions (CLs) in patients with relapsing-remitting (RR) and secondary progressive (SP) multiple sclerosis (MS), and their relationship with cortical atrophy and disability progression. Methods One-hundred seven MS patients (76 RRMS and 31 SPMS), enrolled in a prospective, longitudinal magnetic resonance imaging (MRI) study, were assessed clinically and by brain MRI (including a double inversion recovery sequence) 3 years after study initiation. CL number and volume, T2 white matter (WM) lesion volume, gray matter fraction, and expanded disability status scale (EDSS) were measured. Results At baseline, CLs were detected in 64.4% of RRMS and 74.2% of SPMS patients. During follow-up, 132 new CLs were found in 44 RRMS patients (57.9%; 0.8 new CL/patient/yr) and 61 in 15 SPMS patients (48.4%; 1.0 new CL/patient/yr). Among these patients, only 31 also showed at least 1 new WM lesion. CL number and volume increases were higher in the 52 patients with a clinical worsening compared with those without (p < 0.001). Baseline CL volume correlated with baseline EDSS (r = 0.36, p < 0.001) and EDSS changes over time (r = 0.51, p < 0.001). Baseline CL volume was an independent predictor of EDSS accumulation and GM volume change at follow-up in both patient groups. In SPMS patients, baseline T2 WM lesion volume was another independent predictor of EDSS worsening. Interpretation In relapse-onset MS, CLs accumulate over time and are associated with disability progression. The quantification of CLs might represent an additional useful paraclinical tool to monitor MS evolution. ANN NEUROL 2010;67:376,383 [source]


Gray matter atrophy in multiple sclerosis: A longitudinal study

ANNALS OF NEUROLOGY, Issue 3 2008
Elizabeth Fisher Ph.D.
Objective To determine gray matter (GM) atrophy rates in multiple sclerosis (MS) patients at all stages of disease, and to identify predictors and clinical correlates of GM atrophy. Methods MS patients and healthy control subjects were observed over 4 years with standardized magnetic resonance imaging (MRI) and neurological examinations. Whole-brain, GM, and white matter atrophy rates were calculated. Subjects were categorized by disease status and disability progression to determine the clinical significance of atrophy. MRI predictors of atrophy were determined through multiple regression. Results Subjects included 17 healthy control subjects, 7 patients with clinically isolated syndromes, 36 patients with relapsing-remitting MS (RRMS), and 27 patients with secondary progressive MS (SPMS). Expressed as fold increase from control subjects, GM atrophy rate increased with disease stage, from 3.4-fold normal in clinically isolated syndromes patients converting to RRMS to 14-fold normal in SPMS. In contrast, white matter atrophy rates were constant across all MS disease stages at approximately 3-fold normal. GM atrophy correlated with disability. MRI measures of focal and diffuse tissue damage accounted for 62% of the variance in GM atrophy in RRMS, but there were no significant predictors of GM atrophy in SPMS. Interpretation Gray matter tissue damage dominates the pathological process as MS progresses, and underlies neurological disabillity. Imaging correlates of gray matter atrophy indicate that mechanisms differ in RRMS and SPMS. These findings demonstrate the clinical relevance of gray matter atrophy in MS, and underscore the need to understand its causes. Ann Neurol 2008 [source]

Verbeek MM, Notting EA, Faas B, Claessens-Linskens R, Jongen PJH. Increased cerebrospinal fluid chitotriosidase index in patients with multiple sclerosis. Acta Neurol Scand: 2010: 121: 309,314. © 2009 The Authors Journal compilation © 2009 Blackwell Munksgaard. Objective,,, To investigate chitotriosidase (CTTS) activity in serum and cerebrospinal fluid (CSF) in multiple sclerosis (MS) patients in relation to disease course and CSF markers for immune activation or inflammation. Materials and methods,,, We studied 80 patients with relapsing,remitting MS (RRMS), 24 with secondary progressive MS (SPMS), 20 with primary progressive MS (PPMS) and 29 patients with other neurological disorders (OND). We measured CTTS activity and studied the correlation with CSF mononuclear cell count (MNC) and intrathecal IgG production. Results,,, CTTS activity was significantly higher in CSF, but not in serum, from the total MS group compared with OND and controls. In RRMS and SPMS CTTS, index was increased compared with controls (RRMS, 0.10 ± 0.21; SPMS, 0.10 ± 0.15; controls, 0.021 ± 0.020), but not in PPMS (0.061 ± 0.052). CTTS index was higher in MS patients with elevated MNC or CSF-restricted oligoclonal IgG bands than in MS patients without these CSF findings. Conclusions,,, CTTS index is elevated in RRMS and SPMS. The CTTS index is related to CSF markers of inflammation or immune activation. [source]
