NUTRISEP: Assessment of the nutritional status of patients with multiple sclerosis and link to fatigue.

BACKGROUND: Fatigue is a common complaint in patients with multiple sclerosis (PwMS) and reduces quality of life. Several hypotheses for the pathogenesis of fatigue in MS are proposed ranging from neurological lesions to malnutrition, but none has been conclusively validated through clinical research. OBJECTIVES: The goal of this study was to examine the correlation between fatigue and nutritional status and dietary habits in PwMS. METHODS: This was a cross-sectional, multicenter study conducted at 10 French MS centers and enrolling PwMS with an Expanded Disability Status Scale (EDSS) score between 0 and 7. Plasma level of albumin, magnesium, calcium, iron, vitamin D and B12 evaluated nutritional status. A semi-structured eating behavior questionnaire has been developed to evaluate dietary habits. Evaluation of fatigue used specific questionnaire (EMIF-SEP). Quality of sleep was evaluated by visual analogue scale (VAS), depression with Beck Depression Inventory (BDI-II); dysphagia by DYsphagia in MUltiple Sclerosis questionnaire (DYMUS) and taste disorders by gustometry. Association between nutritional deficiencies and different data such as socio-demographic data, disease characteristics, swallowing and taste disorders, food intake, depression and sleep quality was investigated. RESULTS: A total of 352 patients mean age: 48.1±10.1 years, mean duration of MS: 15.3±9.1 years and median EDSS: 4 were analyzed. Bivariate and multivariate analyses showed a statistically significant correlation between fatigue and depression and use of sleeping pills, while none of the variables related to dietary habits or nutritional status correlated significantly with fatigue. CONCLUSIONS: Dietary habits and nutritional status have little impact on fatigue and general population nutrition recommendations remain the rule for PwMS. In cases of fatigue, specific attention should be paid to depression and use of sleeping pills.

Pulse-triggered DTI sequence with reduced FOV and coronal acquisition at 3T for the assessment of the cervical spinal cord in patients with myelitis.

BACKGROUND AND PURPOSE: DTI is a promising technique for imaging of the spinal cord, but the technique has susceptibility-induced artifacts. We evaluated a pulse-triggered DTI sequence with an rFOV technique and coronal acquisition for the assessment of the cervical spinal cord in patients with myelitis at 3T. MATERIALS AND METHODS: A rFOV acquisition was established by a noncoplanar application of the excitation and the refocusing pulse in conjunction with outer volume suppression. The DTI sequence was performed in the coronal plane in 12 healthy volunteers and 40 consecutive patients with myelitis. Probabilistic tractography of the posterior and lateral funiculi was performed from the C1 to C7 levels. FA, MD, aD, rD, and ratios of aD and rD were measured. RESULTS: In healthy volunteers, mean DTI indices within the whole-fiber pathways were the following: FA = 0.61, MD = 1.17 × 10(-3) mm(2)/s, aD = 1.96 × 10(-3) mm(2)/s, rD = 0.77 × 10(-3) mm(2)/s, and ratios of aD and rD = 2.5. Comparison of healthy controls and patients with myelitis identified statistically significant differences for all DTI parameters. Different patterns of myelitis, including spinal cord atrophy and active inflammatory lesions, were recognized. There was a significant correlation between clinical severity and DTI parameters. CONCLUSIONS: The present work introduces a new approach for DTI of the cervical spinal cord at 3T, enabling a quantitative follow-up of patients with myelitis.

[Epidemiology and clinical assessment of spasticity in multiple sclerosis]. / Épidémiologie et évaluation clinique de la spasticité dans la sclérose en plaques.

Spasticity is a commonly seen symptom in patients with multiple sclerosis (MS). The vast majority of patients will suffer from this symptom during the course of the disease, and one- third of patients considers that spasticity contributes to a greater part of their disability. The symptom is frequently disabling. It can, however, allow some activities to be performed. Treatment of the symptom is sometimes deleterious, which is why strict assessment of the consequences of spasticity and anticipation of the outcome of antispastic treatment are necessary. Clinical scales, such as the Ashworth and Tardieu scales, are used in clinical practice. The essential element is not, however, assessment of the symptom, but its repercussions on activities of everyday life. It is important to make a list of what patients consider to be disabling situations to verify that they are truly consequences of spasticity. Considering the heterogeneity of clinical expression of spasticity in patients with MS, the use of a scale such as goal attainment scaling (GAS) can probably be totally adapted for the assessment of the effects of antispastic treatment.

Evaluation of health-related quality of life, fatigue and depression in neuromyelitis optica.

BACKGROUND: The burden of multiple sclerosis (MS) includes fatigue, depression and worsening of health-related quality of life (HRQOL). These changes have not been yet measured in neuromyelitis optica (NMO). Our aim was to assess the HRQOL, fatigue and depression in NMO. METHODS: We administered French validated self-questionnaires on HRQOL (SEP-59), fatigue (EMIF-SEP) and depression (EHD) to 40 patients followed up in two centres. We assessed the relationship of these parameters with gender, age, disability, disease duration, visual acuity and NMO-antibody status and also compared our results with equivalent data in MS and normal subjects derived from previous studies. RESULTS: Health-related quality of life scores were lower (P < 0.01) in patients with NMO when compared to normal subjects. No significant difference was noted between patients with NMO and MS for most scores, the exceptions being HRQOL related to cognitive function (better in NMO than in MS), HRQOL related to sphincter dysfunction (worse in NMO than in MS) and the psychological dimension of fatigue (milder in NMO than in MS). Disability was the main predictive factor of an unfavourable evolution. DISCUSSION: This study reveals the strong impact of NMO on HRQOL, fatigue and depression and the importance of screening patients, especially the more disabled, so as to initiate suitable treatment.

[Pure subacute pandysautonomia: an assessment of treatment with intravenous polyvalent immunoglobulins]. / Pandysautonomie isolée subaiguë: intérêt du traitement par immunoglobulines polyvalentes.

INTRODUCTION: Acute or sub-acute pure dysautonomia is uncommon. We report a case of sub-acute pure pandysautonomia with favorable outcome after intravenous immunoglobulin therapy. CASE REPORT: A 29-year-old right-handed student, with an uneventful medical history presented, for one month, bilateral loss of visual acuity and digestive disorders, associating diarrhea, vomiting and anorexia. Physical examination revealed bilateral intrinsec oculomotor nerve palsy, a dryness syndrome and severe orthostatic hypotension. Ophthalmologic examination showed bilateral diffuse parasympathic impairment associating an Argyll Robertson pupil and full pupil light reflex abolition. Elevated protein level (0.93g/l) was the only cerebrospinal fluid anomaly. Serum tests were negative for anti-gangliosides antibodies. The patient improved slowly after two series of intravenous immunoglobulin infusions. CONCLUSION: Clinical course and laboratory findings suggest that acute or sub-acute pure pandysautonomia events are likely to be related to acute polyradiculoneuritis. Therefore intravenous polyvalent immunoglobulin infusions should be attempted, even if their efficacy needs to be confirmed.

[Medical-social aspects of multiple sclerosis]. / Les aspects médico-sociaux de la sclérose en plaques.

On a daily basis the quality of life of patients suffering from multiple sclerosis (MS) partially depends on social measures. These are not specific to MS. Patients often need to be helped by hospital or town social services for the numerous and complicated administrative steps to be taken. The information given to a patient is of prime importance concerning his rights, particularly his occupational rights. Many organisations have to be contacted to obtain financial and material aids, even if the latter are considered insufficient in many fields especially for improvements in accommodation. An invalidity card may entitle its holder to certain tax reductions. The competences of the COTOREP are wide-ranging and include the recognition of the handicapped worker, his training and his regarding at work, his orientation and admission into a specialised structure, the degree of his invalidity rate and should his handicap justify it, benefits such as the handicapped adults allowance and the compensatory third person's allowance. It is essential to adopt a multidisciplinary way when dealing with MS in order to provide a better care, experiments in specialised structures and networks are being undertaken. Numerous partners are taking part in these new approaches and patient associations may find their place there. Social aspects have to be taken into account as well in the way the cost of the disease is evaluated in terms of money and humanity.

A semiquantative rating scale for the assessment of signal hyperintensities on magnetic resonance imaging.

Differences in grading signal hyperintensities on magnetic resonance imaging may explain earlier reported conflicting results in studies of normal aging and dementia. We designed a new rating scale in which periventricular and white matter signal hyperintensities as well as basal ganglia and infratentorial signal hyperintensities are rated separately in a semiquantative way. In this study we compared the inter- and intra-observer agreements of this scale to the widely used rating scale of Fazekas. We confirmed the poor to reasonable intra- and inter-observer agreements of the Fazekas scale. The new scale, although more elaborate, provided good agreements with respect to the white matter, basal ganglia and infratentorial signal hyperintensities. In rating periventricular hyperintensities this scale yielded no advantage. It is concluded that this scale may be of use in studies especially focussing on deep white matter pathology on MRI, because it provides more detailed information, with good intra- and inter-observer reliability.
