Health related quality of life and perceived social support in French and Lebanese MS patients: A comparative study.

BACKGROUND: The perception of diagnosis announcement, the social support and the coping strategies seem to be determining factors for the quality of life of multiple sclerosis (MS) patients, with possible transcultural variations. This study explores these psychosocial dimensions in Lebanese and French MS patients. METHODS: For this cross-sectional multi-center study, 8 questionnaires were used to assess quality of life, family support, coping strategies, mood, fatigue, stress, and hopelessness in MS patients. 7 were translated into Arabic and then back translated into French. These were administered to a group of Lebanese MS patients and compared to an MS sample from France. The data was collected for both populations and analyzed. RESULTS: A total of 107 patients were included, 46 Lebanese and 61 French. The majority of MS patients were young females with a high level of education, relapsing remitting form of MS and a low level of disability. Both populations exhibited comparable quality of life and answers on the questionnaires regarding mood disorders, hopelessness, and perceived stress. However, the French patients had significantly more fatigue. Perceived social support given by family was considered greater in the French group compared to the Lebanese one. Also, maladaptive coping strategies (such as self-distraction, denial, behavioral disengagement, substance use, self-blame, venting) were used more frequently by the French population compared to the Lebanese, and this correlated with higher anxiety scores. Diagnosis communication was overall brief, informative, and satisfying in both populations. CONCLUSION: This study highlighted transcultural differences between French and Lebanese MS patients mainly in social support and coping strategies.

Clinical, imaging and follow-up study of optic neuritis associated with myelin oligodendrocyte glycoprotein antibody: a multicentre study of 62 adult patients.

BACKGROUND AND PURPOSE: There are few clinico-radiological data on optic neuritis (ON) with myelin oligodendrocyte glycoprotein antibody (MOG-IgG). The objective was to characterize the clinico-radiological phenotype and outcome of patients with MOG-IgG-related ON. METHODS: The records of all adult patients admitted in three medical centres with MOG-IgG-associated ON who underwent orbital and brain magnetic resonance imaging (MRI) at the acute phase were reviewed. Spinal cord MRI within 1 month from the ON and all of the follow-up MRI were reviewed. RESULTS: Of 62 patients, 41.9% had bilateral ON and 66.2% optic disc swelling. On initial MRI, lesions were anterior (92%), extensive (63%) and associated with optic perineuritis (46.6%). Silent brain lesions were found in 51.8% of patients but were mainly non-specific (81%). Of 39 individuals with spinal MRI at onset, nine had abnormal findings (four were asymptomatic). Two symptomatic patients had longitudinally extensive myelitis with concurrent H-sign. At last follow-up, 5% of patients had visual acuity ≤0.1. Brain MRI remained unchanged in 41 patients (87%). CONCLUSIONS: Our study supports a mostly benign ophthalmological course of MOG-IgG-associated ON, despite initially longitudinally extensive lesions and development of optic nerve atrophy on orbital MRI. Spinal MRI could be of interest in detecting silent suggestive lesions.

Acute idiopathic optic neuritis: not always benign.

BACKGROUND AND PURPOSE: Few recent data are available concerning idiopathic optic neuritis (ON). We aimed to describe a large cohort of patients with idiopathic ON. We compared this cohort with patients with ON related to myelin oligodendrocyte glycoprotein (MOG) or ON related to aquaporin-4 (AQP4) antibodies. METHODS: This was a monocentric retrospective observational study. Inclusion criteria for idiopathic ON were as follows: age ≥ 16 years, follow-up of at least 2 years, negative for antibodies against MOG and AQP4 immunoglobulin G, and no magnetic resonance imaging (MRI) lesions suggestive of demyelination (two brain MRI scans, one at baseline and one during follow-up, and one spinal cord MRI scan). RESULTS: Among 23 patients with idiopathic ON (female, 82.6%; median age, 36 years; median follow-up time, 41.4 months), 56.5% had recurrent ON (median time to a second ON episode, 6 months). The final visual acuity in this group (median, 0; mean, 0.43; range, 0-3) was similar to that in the AQP4 group (n = 18; P-value after Bonferroni correction = 0.936) but worse than that in the MOG group (n = 25; P-value after Bonferroni correction = 0.019). At the last evaluation, visual acuity levels were ≤0.5 and <0.2, respectively, in 36.8% and 21% of the idiopathic ON group, 58.3% and 26.7% of the AQP4 group, and 0% and 0% of the MOG group. CONCLUSION: The recovery of visual acuity among patients with idiopathic ON was poor, similar to that observed in the AQP4 group.

Is the Choosing Wisely® campaign model applicable to the management of multiple sclerosis in France? A GRESEP pilot study.

BACKGROUND: Launched in the US in 2012, Choosing Wisely® is a campaign promoted by the American Board of Internal Medicine (ABIM) Foundation with the goal of improving healthcare effectiveness by avoiding wasteful or unnecessary medical tests, treatments and procedures. It uses concise recommendations produced by national medical societies to start discussions between physicians and patients on the relevance of these services as part of a shared decision-making process. The Multiple Sclerosis Focus Group (Groupe de Reflexion Autour de la Sclérose en Plaques; GRESEP) undertook a pilot study to assess the relevance and feasibility of this approach in the management of multiple sclerosis (MS) in France. METHODS: Recommendations were developed using the formal consensus method from the guidelines of the French National Health Authority (HAS). A steering committee selected the themes and drafted concise evidence reviews. An independent rating group then assessed these recommendations for clarity, relevance and feasibility. RESULTS: Seven recommendations were accepted: (1) avoid systematic ordering of multimodal evoked potential studies for diagnosing MS; (2) do not treat MS relapses with low-dose oral corticosteroids; (3) when treating MS relapse with high-dose corticosteroids, the systematic use of the intravenous route is unnecessary if the oral route can be used; (4) systematic hospitalization is not necessary for treating MS relapse with high-dose corticosteroid therapy, particularly if the oral route is used, except for the first treated relapse and the presence of exclusion or non-eligibility criteria; (5) in the absence of clinical signs or symptoms of urinary infection, avoid systematic screening with urine microscopy and culture before the administration of corticosteroid therapy for MS relapse in patients using intermittent self-catheterization; (6) avoid antibiotic treatment of clinically asymptomatic MS patients using intermittent self-catheterization, even if urine microscopy and culture reveal the presence of microorganisms; and (7) avoid introducing symptomatic drug treatment for MS-related fatigue. CONCLUSION: This pilot study, the first of its kind in France, has demonstrated the relevance and feasibility of adapting the Choosing Wisely® model to MS by practitioners specializing in the disorder. However, the acceptability of these recommendations by other practitioners in other specialist fields as well as their impact on everyday clinical practices now need to be studied.

Etiologies of acute demyelinating optic neuritis: an observational study of 110 patients.

BACKGROUND AND PURPOSE: New criteria for the diagnosis of multiple sclerosis (MS) and discovery of myelin oligodendrocyte glycoprotein (MOG) or aquaporin-4 (AQP4) antibodies (Abs) have changed the management of optic neuritis (ON). Our aim was to specify, in view of these recent advances, the etiologies of acute demyelinating ON for consecutive patients. METHODS: Retrospective database analysis was undertaken of consecutive adult patients with acute ON admitted from 1 December 2014 to 31 January 2016. Diagnosis of MS was made according to the 2010 McDonald criteria. Patients with Abs to AQP4 or MOG were classified as ON-AQP4 and ON-MOG, respectively. Patients who did not fulfill the diagnostic criteria and were negative for AQP4 and MOG Ab tests were classified as having idiopathic ON. RESULTS: Of 110 patients assessed, 78 had ON related to MS (70.9%). All patients without MS were tested for AQP4 and MOG Abs: 11 had MOG Ab (10%), 5 had AQP4 Ab (4.5%) and 16 were considered as having idiopathic ON (14.5%). Presence of intrathecal IgG oligoclonal bands was strongly associated with MS (mean, 88.4% vs. 34.4% in patients without MS; after Bonferroni correction, P < 0.0001). CONCLUSIONS: Optic neuritis related to MOG Ab was the second cause identified of demyelinating ON in our center. Idiopathic ON was as frequent as both ON-AQP4 and ON-MOG combined.

Targeted clinical audits immediately following the establishment of clinical practice guidelines for multiple sclerosis in 17 neurology departments: A pragmatic and collaborative study.

UNLABELLED: Following the publication practice guidelines for multiple sclerosis by a group of neurologists (multiple sclerosis study group [GRESEP]), the primary objective of this study was to compare the reality of practice to the guidelines according to the targeted clinical audit (TCA) method. The study was conducted at 17 neurology sites and was administered during two periods of MS care (diagnostic - TCA-DIAG, and disease course - TCA-EVOL). Two complementary surveys were done on the record keeping and the root causes of the deviations. The percentages of compliance ranged from 8 to 98% for the TCA-DIAG, and from 15 to 99% for the TCA-EVOL, with wide disparity between sites. The audits were able to identify causes of the flaws in traceability or accessibility. At the end of the study, despite its limitations, we think that the sharing of the results from different sites provided interesting approaches for the use of the assessment criteria defined by GRESEP in a complete audit cycle. This study is to our knowledge the first report of an experiment in which guidelines were created, and subsequently followed by the development of assessment criteria and then the performance of targeted clinical audits using them, all by the same participants. CONTEXT: Clinical practice guidelines (CPGs) are intended to help practitioners and patients make informed treatment choices, but their integration into actual practice remains problematic. This study was done immediately following the publication of CPGs for multiple sclerosis (MS) by the multiple sclerosis study group [GRESEP]. The primary objective was to generate quality criteria, to test them within the same group, and to analyze the observed deviations. MATERIALS AND METHODS: The study was conducted in the 17 voluntary departments that had participated in the development of the CPGs. The targeted clinical audit method was administered during two periods of MS care (diagnostic - TCA-DIAG, and disease course - TCA-EVOL). All the files were evaluated by a clinical research technician using digital format, which ensured thoroughness of the collection. Two complementary surveys were done on the record keeping and the potential causes of the deviations. RESULTS: The percentages of compliance to the criteria ranged from 8 to 98% (out of 240 files) for the TCA-DIAG, and from 15 to 99% (221 files) for the TCA-EVOL, with wide disparity between sites (interquartile distance ranges: TCA-DIAG between 0% and 55%; TCA-EVOL between 0% and 70%). The mean percentage of compliance with all the criteria as measured by the TCA-DIAG was 83.9% for the sites with digital files vs. 76.4% for those with only paper files (P<0.01). For the TCA-EVOL, the difference was not significant. Explanations for the observed deviations were suggested (1 to 9 according to the participants). DISCUSSION AND CONCLUSION: The quantified results could not be compared to other studies given the unique nature of the experiment. The importance of the traceability of practices in the patient files was discussed and assessed with regard to continuity and safety of care, as well as the medical-legal perspectives. Causes of lack of compliance were suggested (particularly the absence of reminders, the lack of means and/or time). Despite the limitations of the study, we think it is advisable that when a group becomes involved in the development of CPGs that they follow with the development of assessment criteria in order to evaluate the validity as well as their character as intermediate indicators of the quality of practices.

Multiple sclerosis and pregnancy.

The question of pregnancy in patients with multiple sclerosis is regularly raised due to the prevalence of the disease in middle age women. The multiple sclerosis think tank (Groupe de Réflexion sur la Sclérose en Plaques [GRESEP]) decided to develop recommendations on this issue, with consideration to both the impact of multiple sclerosis on pregnancy, and that of pregnancy on the disease. As with topics of previous works, the formal expert consensus method was used. The working group was composed of hospital-based and private practice neurologists. The reading group was composed of neurologists, anaesthetists and obstetricians. Each recommendation is presented with the relevant level of consensus.

Recommendations for useful serum testing with suspected multiple sclerosis.

Several practical questions useful for management of patients with multiple sclerosis remain unanswered in the current scientific literature. Decisions are often made individually, without the support of solid scientific evidence. In order to facilitate concurring practices, we present guidelines concerning useful serum exams for the diagnosis of multiple sclerosis. The methodology used was that of a formal expert consensus. A working group performed a systematic analysis of the literature, taking into account both previously existing recommendations and original articles, and then drafted guideline proposals. These proposals were subjected to the critical review of a rating group. Three written drafts, followed by rating of the guideline proposals culminated in a consensual document, which was submitted for review to a second independent reading group. The final resulting document provided the material for the present article, in which each recommendation is presented with its grade according to the level of proof or its degree of consensus in the absence of scientific proof.

Recommendations for the detection and therapeutic management of cognitive impairment in multiple sclerosis.

The aim of the Multiple Sclerosis Think Tank (Groupe de réflexion sur la sclérose en plaques [GRESEP]) is to prescribe recommendations following a systematic literature search and using a Rand Corporation and California University (RAND/UCLA) appropriateness derived method, in response to practical questions that are raised in the management of patients with multiple sclerosis (MS). The topics of this working program were chosen because they were not addressed in the French recommendations and because of the few data in the literature that enabled practices to be based on validated data. Following the theme on useful serum testing with suspected multiple sclerosis, the subjects of the present work concern the detection and management of cognitive impairment in the beginning stages of the disease course. Two clinical questions were asked: which complementary exams (besides physical examination and neuropsychological tests) would help in the screening of cognitive impairment at the beginning of the disease? What care management should the person with MS and cognitive impairment be offered (treatments and neurocognitive rehabilitation)? The recommendations are the result of a consensus amongst a working group, a rating group and a reading group comprised of hospital neurologists involved in the management of patients with multiple sclerosis. Each recommendation is presented with the degree of consensus that it was accorded.

Recommendations for the management of multiple sclerosis relapses.

The aim of the Multiple Sclerosis Think Tank (Groupe de Réflexion sur la Sclérose en Plaques [GRESEP]), composed of hospital neurologists involved in the management of patients with multiple sclerosis, is to provide recommendations in response to clinical questions that are raised when managing these patients. After work done on the themes of useful serum testing with suspected multiple sclerosis, detection and management of cognitive disorders early in the course of the disease, and definition and early management of the disease, GRESEP wanted to develop recommendations on the management of multiple sclerosis (MS) relapse. Following a systematic analysis of the literature, the procedure of formal expert consensus enabled consensual recommendations among a working group, a rating group and a reading group to be written. Each recommendation is presented with its grade or the degree of consensus that it was accorded.

Recommendations for a definition of multiple sclerosis in support of early treatment.

The aim of the Multiple Sclerosis Think Tank (Groupe de Réflexion sur la Sclérose en Plaques: GRESEP), composed of hospital neurologists involved in the management of patients with multiple sclerosis, is to provide recommendations in response to clinical questions that are raised when managing these patients. After work done on the themes on useful serum testing with suspected multiple sclerosis, as well as the detection and management of cognitive disorders early in the course of the disease, the subject of the present work is the early definition and early treatment of the disease. Following a systematic literature review, a RAND/UCLA appropriateness-derived method enabled consensual recommendations among a working group, a rating group and a reading group to be developed and formulated. Each recommendation is presented with the degree of consensus that it was accorded.

[Current treatment of multiple sclerosis]. / Actualités thérapeutiques de la sclérose en plaques.

Since commercialisation of the first immunomodulatory drug (IMD) for multiple sclerosis (subcutaneous interferon beta-1b) in 1995, three new IMD have been on the market: two interferons (intramuscular interferon beta-1a and subcutaneous interferon beta-1a) and glatiramer acetate. These four immunomodulatory drugs have a similar efficiency: they reduce by about 30% the relapse rate of treated patients compared to untreated patients. Their effect on disability is moderate mainly due to the reduced relapse rate. Lately, in 2002, mitoxantrone was approved for aggressive relapsing-remitting MS and in 2007 the first monoclonal antibody (natalizumab) was approved for active relapsing-remitting MS.

[White matter lesions leading to the diagnosis of pseudoxanthoma elasticum]. / Hypersignaux de la substance blanche révélant un pseudoxanthome élastique.

Pseudoxanthoma elasticum (PXE) is an inherited connective tissue disease characterized by skin, eye, cardiovascular, and, less often, cerebrovascular manifestations. We report the case of a 32-year-old woman who presented with fortuitously discovered cerebral white matter lesions. The pattern of the lesions was compatible with vascular leucopathy. Neurological examination, CSF and biological assessment were normal. Physical examination demonstrated cutaneous lesions characterized by yellowish papules in the neck and axilla with calcification of elastic fibres showed on the skin biopsy and retinal angioid streaks, which made PXE a plausible diagnosis. Sequencing of the ABCC6 gene confirmed PXE. Thus, PXE must be considered when confronted with cerebral microangiopathy of undetermined origin.

Unexpected multiple sclerosis: follow-up of 30 patients with magnetic resonance imaging and clinical conversion profile.

The concept of preclinical multiple sclerosis is now well recognised, and a diagnosis of silent brain T2 lesions is frequent because of the ease of performing MRI. Nevertheless, patients with incidental brain MRI fulfilling Barkhof- Tintoré criteria are more rare. We report a descriptive retrospective study of clinical and 5 year MRI follow-up in patients with subclinical demyelinating lesions fulfilling MRI Barkhof-Tintoré criteria with a normal neurological examination. 30 patients were identified and the first brain MRI was performed for various medical events: headaches (n = 14), migraine with (n = 2) or without (n = 4) aura, craniocerebral trauma (n = 3), depression (n = 3), dysmenorrhoea (n = 2), epilepsy (n = 1) and cognitive changes (n = 1). Mean time for the second brain MRI was 6 months (range 3-30). 23 patients had temporospatial dissemination (eight with gadolinium enhancement). 11 patients had clinical conversion: optic neuritis (n = 5), brainstem (n = 3), sensitive symptoms (n = 2) and cognitive deterioration (n = 1). Eight (72%) already had criteria of dissemination to space and time before the clinical event. Mean time between the first brain MRI and clinically isolated syndrome (CIS) was 2.3 years. To our knowledge, this is the first cohort of CIS with preclinical follow-up. Early treatment should be discussed in view of the predictive value on conversion of the MRI burden of the disease.

[Contribution of cognitive evoked potentials for detecting early cognitive disorders in multiple sclerosis]. / Intérêt des potentiels évoqués cognitifs dans la détection des troubles cognitifs précoces dans la sclérose en plaques.

In Multiple Sclerosis (MS), one of the most frequent neurological diseases in young adults, cognitive dysfunctions have been under considered whereas their evolution may produce a fronto-sous-cortical deterioration and more than half of the MS patients present such dysfunctions. Nevertheless sensory evoked-potentials are classically used in this disease, event-related potentials (ERP) are not included in the clinical exploration of MS. Two studies are presented aimed at further tracking the usefulness of ERP for detecting early cognitive dysfunctions in MS. All of the patients presented a relapsing remitting MS for less than 5 years with a moderate physical handicap and complained from their memory. They performed a neuropsychological set and ERP were elicited using the oddball paradigm in both modalities, visual and auditory. In the first study, 10 patients without cognitive dysfunction at the neuropsychological evaluation and 10 patients with an attention deficit participated with 10 age-matched controls. In the second study, 10 patients with memory impairment at the neuropsychological evaluation and 10 age-matched controls were included. Our data argue for an earlier modification of ERP parameters in the visual modality than in the auditory one, even before the modification of cognitive scores. In both studies, P300 parameters were correlated to neuropsychological performances (and especially to the attention examination in the first study and to memory tests in the second study) in both modalities. Taking into account the clinical usefulness of ERPs, it is nowadays important to include this electrophysiological method in evaluation and follow-up of MS, and not only using the auditory modality but also the visual presentation in order to detect earlier cognitive dysfunctions even before modification of neuropsychological performances.

[Early detection of cognitive impairment in relapsing-remitting multiple sclerosis: functional-anatomical correlations and longitudinal follow-up]. / Troubles cognitifs et sclérose en plaques rémittente: intérêt de leur détection précoce: corrélations anatomo-fonctionnelles et suivi longitudinal.

INTRODUCTION: Cognitive impairment is frequent in relapsing remitting Multiple Sclerosis and is often diagnosed after disruption of occupational and social relations. METHODS: We studied at baseline a homogeneous population of 32 RRMS patients, diagnosed for less than 5 years, with spontaneous memory complaints, and 20 controls. Sixteen patients were followed for 2 years, combining physical examination, neuropsychological tests, and brain MRI. Neuropsychological tests used evaluated memory capacities, attentional capacities, executive functions, language, and visuo-constructive praxis. Lesion load on brain MRI was measured with semi-automatic segmentation procedures and manual control. RESULTS: Eighty percent of patients presented cognitive impairment, and this proportion was higher than that found in the literature. These disorders were more marked for verbal episodic memory, attention, and executive functions. Patients with brain MRI that initially fulfilled the Barkhof criteria and those with callous lesions had more memory disorders. No link between global T1 and T2 lesion loads and neuropsychological scores was found. A statistical link between posterior fossa lesions and attentional disorders was shown. In the longitudinal follow-up, patients had better performances in memory and attentional domains, and a lower number of cognitive domains with dysfunction for each patient. This improvement on neuropsychological tests, whereas EDSS levels were stable, underlined a possible test-retest effect. CONCLUSION: During the initial phase of the disease, most of the relapsing remitting patients present a mild cognitive impairment. Early detection, therapeutic propositions, and recognition of disorders are necessary.

[Recurrent aseptic meningitis associated with primary biliary cirrhosis]. / Méningite récurrente aseptique associée à une cirrhose biliaire primitive.

INTRODUCTION: The etiological diagnosis of recurrent aseptic meningitis often requires difficult investigations. We report a case of recurrent aseptic meningitis associated with a primary biliary cirrhosis. CASE REPORT: A 37-year-old woman presented four recurrences of isolated meningitic syndrome with fever. Intravenous steroid treatment was effective. Investigations revealed an old right tympano-labyrinthine fracture with, on MRI, an abnormal enhancement of the posterior wall of the internal auditory canal. Serum tests were also significantly positive for antimitochondria antibodies subtype M2. CONCLUSION: Definitive diagnosis was recurrent puriform aseptic meningitis secondary to an inflammatory non-septic ears-nose-throat focus in a latent autoimmune context of primary biliary cirrhosis. To our knowledge, this is the first case reported in literature.

[The contribution of automatic anatomical matching of sequential brain MRI scans in the monitoring of multiple sclerosis lesions]. / Intérêt du recalage automatique des IRM cérébrales dans le suivi des scléroses en plaques.

INTRODUCTION: Magnetic resonance imaging (MRI) has transformed management of patients with multiple sclerosis. The exact contribution of brain MRI remains a subject of debate, but it is generally considered to provide a more specific and more sensitive outcome measure for monitoring purposes and for testing new therapies. The choice of MRI techniques, and measurement reproducibility for multiple sclerosis brain lesions are not defined with precision for routine practice. There are many sources of error when comparing successive images which can be overcome to some extent with repositioning and image processing techniques. METHODS: We evaluated the impact of image repositioning on treatment decision-making for twelve relapsing remitting patients. Brain MRIs were performed every three months for a one-year period. Two neurologists interpreted the non-repositioned and repositioned images giving their analysis of changes in the lesions visualized on the T2 sequences and their therapeutic decisions. RESULTS: For the first neurologist, analysis of the non-repositioned images yielded six patients whose lesions had worsened while for the repositioned images there were only three. For the second neurologist, four patients had more lesions with the non-repositioned images and only three with repositioning. The subjective interpretations were the same for the two neurologists when they used repositioned images. CONCLUSIONS: Comparison by two neurologists of non-repositioned and repositioned MRI, with no other image processing, affected the analysis and in certain cases propositions for treatment.
