[Interferons and neurologic diseases].

PURPOSES: Therapeutic strategies using interferons in neurology are limited to multiple sclerosis. In this disease, only beta interferons are used and now considered as a first line treatment in the relapsing-remitting forms of the disease. MAIN POINTS: Beta interferons have reduced the relapse rate by approximately 3% and also reduced the risk of disability progression. They have also favorably influenced the brain lesions on MRI. Numerous data have stressed the importance of starting treatment as early as possible. In the secondary form of the disease, the impact of beta interferons are still discussed. In some clinical endpoints, a dose-response has been demonstrated, probably related to the frequency of injections. Side effects are acceptable despite the high frequency of flu-like syndrome. PERSPECTIVES: Recent data argue for beta interferon treatment after the first demyelinating episode in subjects at risk for early new relapses. In some patients, in cases of treatment failure, combination strategies, including beta interferons, should be addressed in the near future. Interferons were also tested with disappointing results in other neuro-inflammatory disorders, such as chronic inflammatory demyelinating neuropathies.

Quality of life in multiple sclerosis: influence of interferon-beta1 a (Avonex) treatment.

BACKGROUND: Numerous data argue for initiating treatment with interferon-beta (IFN-beta) at an early stage in multiple sderosis (MS). The consequences of its use may negatively influence the MS patient's quality of life (QoL). OBJECTIVE: To evaluate the QoL of MS patients before and after a one-year period of treatment with IFN-beta1a (Avonex). PATIENTS AND METHODS: QoL was assessed using the SF-36 in 121 relapsing-remitting MS patients. We compared QoL before and after treatment and with data from a normal population. We also studied the possible influence of disease progression on the SF-36 scores. RESULTS: One hundred six patients completed the study (87%). Compared to a normal population, patients were, at baseline, worse off for all QoL scales, varying from a minimum decrease of 0.73 SD in mental health, to a maximum decrease of 1.55 SD in general health. After treatment, we found no significant changes in any of the QoL scores, except for physical function, where we noted a slight but significant decrease (p = 0.03). Furthermore, there was no significant change either in the physical component summary (PCS) or mental component summary (MCS). The 'reported health transition' item was significantly improved compared to baseline (p = 0.001). At indusion, significant correlations were found between EDSS scores and scores of physical function (p < 0.001), role - physical (p < 0.01), general health and social function (both p < 0.01), and with the PCS (p < 0.01). Patients with dinical relapses and/or disability progression had a more significant decease in physical function (p < 0.05) and also in social function (p < 0.05). CONCLUSION: The QoL, assessed by the SF-36 scale, is correlated with disability in MS. IFN-beta1a treatment (Avonex) has no negative effect on MS patient's QoL.

[Treatment of progressive multiple sclerosis with cyclophosphamide].

Intravenous (IV) cyclophosphamide is currently used in secondary progressive (SP) and Primary progressive (PP) Multiple Sclerosis (MS) but its efficacy remains uncertain. Furthermore, it is necessary to determine which MS should be successfully treated with IV cyclophosphamide. We retrospectively investigated 111 consecutive patients with progressive MS (21 PPMS and 90 SPMS) treated in an open label fashion with IV cyclophosphamide. We analysed clinical data (gender, age, duration of progression, primary versus secondary MS). The treatment response was assessed by EDSS change after 6 months and 1 year of treatment. The annual relapse average decreased from 1.92 before treatment to 0.39 during the treatment. Age and gender did not influence response to therapy. We did not find any difference of response between PPMS and SPMS. Duration of the progressive phase in SPMS was not a predictive factor of efficacy. A better response was noted in SPMS patients with surimposed relapses than in patients without relapses during the year before treatment (p<0.05). Furthermore, the better response in SPMS patients with relapses before treatment suggests that it is necessary to treat when MS is still in an inflammatory stage.

[Primary progressive forms of multiple sclerosis: application of the new diagnostic criteria in French].

Approximately 15 p.100 of all cases of multiple sclerosis (MS) are primary progressive multiple sclerosis (PPMS). Diagnosis is however frequently delayed due to the lack of relapse. The commonly used Poser criteria established in 1983 are not directly applicable to this subgroup of MS patients. In 2000, Thompson et al proposed new diagnostic criteria for PPMS. The aim of our study was to apply retrospectively these new criteria to a cohort of patients from northern France (G-SEP cohort). The cohort included 184 patients (94 women and 90 men, sex ratio=1.04). Mean age at disease onset was 40.3 years (18-67 years) and mean follow-up was 9.9 (1-39 years). Only one patient was older than 65 years but 13 patients (7.1 p.100) were younger than 25 years. Patients were classed as having definite, probable or possible PPMS on the basis of clinical, MRI, cerebrospinal fluid and visual evoked potential (VEP) data. Most of the patients (61.4 p.100) had one symptom at onset; spastic paraparesis was frequent (79 p.100). Mean delay to diagnosis was 4.4 years. Ten patients (5.4 p.100) were surgically treated for cervic arthrosic myelopathy. Mean EDSS score at the end of follow-up was 5.8 (3-10). MRI was positive in 87.3 p.100 of the patients. Oligoclonal bands were found in 78.2 p.100. VEPs ware abnormal in 79.9 p.100 of the patients. Applying the Thompson criteria, 57.7 p.100 of the patients had definite PPMS, 38.7 p.100 probable PPMS. Our results are very similar to previous studies and confirm the usefulness of the new proposed criteria, which however should be prospectively tested to determine sensitivity and specificity in a new cohort of patients.

[Chronic polyradiculoneuritis disclosing sarcoidosis].

Peripheral Nervous System (PNS) involvement occurs in 10 to 40 percent of patients presenting with sarcoidosis. Axonal polyneuropathies and mononeuropathies are the most frequently reported whereas acute or chronic polyradiculoneuritis are rarely described. We report the case of a 54 year-old-woman admitted for a progressive sensorimotor deficit of the lower limbs. Bilateral ocular redness corresponding to an uveitis was also observed. Neurological examination and electrophysiological data were consistent with a chronic polyradiculoneuritis. The neurological status of the patient improved after six months of treatment with oral corticotherapy associated with immunosuppressive treatment. Our case allows a review of the literature concerning PNS involvements and treatments in sarcoidosis.

[Candida albicans meningoencephalomyeloradiculitis].

A 25-year-old immunocompetent male heroin addict was admitted for acute confusion associated with gait disorders of three month duration. The diagnosis was meningoencephalomyeloradiculitis secondary to Candida albicans infection. Outcome was good after a 6-month regimen with antifungal drugs. Neurological complications of Candida albicans infection are rare and prognosis is generally poor. This case report illustrates diagnostic and therapeutic difficulties encountered.

[Epstein-Barr meningoencephaloradiculitis in a immunocompetent woman].

Neurological manifestations of viral diseases are predominantly secondary to herpes viridae infections. Among them Epstein-Barr (EBV) infections are rare particularly in immunocompetent adults. A 52 year old right-handed woman was admitted for progressive walking difficulties. She presented a proximal limb weakness with proprioceptive ataxia and pain because of lumbosacral radiculopathy confirmed by electromyography. Drowsiness and mnesic troubles were explained by encephalitis on electroencephalography. Brain MRI showed an enhancement of the sub-arachnoïd spaces. The diagnosis of meningoencephaloradiculitis due to primary EBV infection was supported by a mononucleosis syndrome, an increased antibody level and positive EBV PCR in the CSF. Clinical features spontaneously improved without antiviral treatment. Primary EBV infections are rare in adults, as more than 95p.cent of them are positive for EBV serology after 20 years of age. EBV PCR is CSF in an important diagnostic tool allowing to stop antiviral therapies in these cases having a good prognosis.

[Late onset multiple sclerosis].

Multiple sclerosis (MS) with clinical onset after 50 years old is unusual and frequently misdiagnosed. Clinical presentation and course seem also to be different that in MS occurring between 20 and 50 years old. The aim of this study was to evaluate the clinical and paraclinical characteristics of late onset MS. We respectively studied MS patients older than 50 years at the onset of the disease. We evaluated demographical data, clinical symptoms, cerebrospinal fluid (CSF), visual evoked potentials (VEPs) and MRI of these patients. We also studied clinical data during the follow-up with the occurrence of new symptoms and the evolution of the disease by the index of progression (EDSS unit per year). In a population of 1 417 MS, 3.4 p.cent had their first symptoms at 50 years old or older and 0.45 p.cent after 59 years old. At the time of the study patients had more frequently a progressive form: 37 p.cent had a primary progressive form and 35 p.cent a secondary progressive MS. None of the patients with onset after 60 years old had relapsing remittent MS. Motor symptoms were the most common neurologic presentation (54 p.cent of patients). Very few patients had a clinical optic nerve involvement during the follow-up. The mean progression index was 1 suggesting a most severe evolution in this subgroup of MS patients. 76 p.cent of patients had oligoclonal banding detected by CSF electrophoresis. The VEPs were abnormal in 81 p. cent of patients tested. 71 p.cent of the brain MRI were consistent with the diagnosis of MS. 60 p.cent of patients had spinal cord MRI abnormal. This study highlights the differences between the late onset MS and earlier onset. As previously reported, our study underlines the high frequency of progressive course, motor function involvement and poor prognosis.

[Bilateral phrenic nerve paralysis, dysautonomia and restrictive cardiomyopathy in a case of POEMS syndrome].

We report a case of POEMS syndrome (Polyneuropathy, Organomegaly, Endocrinopathy, M protein and Skin changes) with unusual clinical features. A 62-year-old woman presented a severe polyneuropathy with dysphonia and vegetative symptoms, including bradycardia and sphincterial disorders. The clinical examination showed facial hyperpigmentation, cachexia, anasarca and splenomegaly. She also presented restrictive cardiomyopathy and endocrine disturbances. Nerve conduction studies revealed a severe demyelinating sensorimotor neuropathy. Cerebrospinal fluid analysis showed an elevated protein level. We detected a biclonal gammapathy (Ig G and Ig A with lambda light chain) and lytic pelvic bone lesions. Later, she developed a severe ventilatory failure due to a bilateral phrenic nerve paralysis leading to a mechanical ventilation. Steroids followed by localized radiotherapy partially improved the respiratory status and stabilized the neuropathy. Phrenic nerve paralysis, restrictive cardiomyopathy, vegetative symptoms and cranial nerve palsy are exceptional in POEMS syndrome. Moreover, this case emphasizes the importance of radiological investigations since the discover of plasmocytoma may improve the prognosis of POEMS syndrome.

The prevalence of Sjögren syndrome in patients with primary progressive multiple sclerosis.

OBJECTIVE: To assess the prevalence of Sjögren syndrome (SS) in patients with primary progressive MS (PPMS). BACKGROUND: SS may be considered in the differential diagnosis of MS. Age at onset and clinical presentation are similar in SS and PPMS. However, occurrence of SS in definite cases of PPMS has been recently reported. METHODS: Proposed clinical and laboratory diagnostic criteria for SS were systematically assessed in 60 consecutive patients with PPMS. The authors questioned all patients about xerophthalmia and xerostomia, biopsied minor salivary glands, and performed a Schirmer test, a salivary gland scintigraphy, and anti-Ro (SSa) and anti-La (SSb) serologies. RESULTS: Ten patients (16.6%) met four or more criteria for SS. This prevalence is higher than in the general population (1 to 5%) and implies that SS can mimic PPMS. CONCLUSIONS: The authors propose that SS should be screened for systematically in patients with PPMS.

Long-term follow-up of neurosarcoidosis.

The authors evaluated the long-term clinical outcome of neurosarcoidosis and determined predictive factors of disease course. Twenty-seven patients with neurosarcoidosis were followed for at least 5 years from the onset of neurologic symptoms. Patients with CNS involvement during the course of the disease had a higher Modified Oxford Handicap Scale score than those with peripheral nervous system involvement (p < 0.02). CNS involvement may be a predictive factor for a less favorable disease course. Early and intensive treatment should be considered in such cases.

Pupillary disturbances in multiple sclerosis: correlation with MRI findings.

UNLABELLED: Autonomic nervous system disturbances such as pupillary abnormalities have rarely been evaluated in multiple sclerosis (MS). However, pupillary impairment is not uncommon in MS and its origin is still unclear. The aim of this study was to investigate pupillary disturbances in MS and to try to correlate pupillary defects with spinal cord and brainstem magnetic resonance imaging (MRI) findings. We prospectively studied 45 MS patients and 30 normal subjects. METHODS: The pupillary contraction latency and the amplitude of contraction were recorded by pupillometry. We also determined afferent and efferent pathway defects by comparing the direct and consensual pupillary reflexes. We evaluated brainstem and spinal cord demyelinating lesions and spinal cord cross-sectional area on MRI. At least one pupillometric parameters were significantly impaired in 60% of patients and in none of the controls. We did not find any correlation between pupillary defect and demyelinating lesions on MRI. The most frequent abnormality was efferent pathway shift and this was correlated with spinal cord atrophy (P<0.02). These results confirm that the autonomic nervous system, and especially pupillary function, is frequently impaired in MS. The parasympathetic system is most commonly affected and this is most likely linked to axonal loss (demonstrated by spinal cord atrophy) rather than to demyelinating lesions.

Autonomic dysfunction in multiple sclerosis: cervical spinal cord atrophy correlates.

Autonomic dysfunction has rarely been studied in patients suffering from multiple sclerosis (MS). Some hypotheses have concerned the pathophysiology, especially with regard to a possible spinal cord origin. However, there have been no previous studies on autonomic dysfunction in MS and spinal cord lesions. This study assessed the frequency of autonomic dysfunction (AD) in MS and the correlation to spinal cord magnetic resonance imaging (MRI) findings. We prospectively studied 75 MS patients (25 with relapsing-remitting forms, 25 with secondary progressive forms and 25 with primary progressive forms). We performed sympathetic skin response, R-R interval variability and orthostatic hypotension testing. Spinal cord MRI was performed to detect demyelinating lesions (sagittal and axial plane) or spinal cord atrophy. Clinical and laboratory evidence of AD was found in 84% and 56% of MS patients, respectively. The correlation of the latter with disability was evaluated using the Extended Disability Status Scale. AD was more frequent in primary progressive MS than in the other two forms. AD was correlated with spinal cord cross-sectional area reduction but not with spinal cord hyperintensities. This study confirms that the frequency of AD in MS, especially in primary progressive forms, has until now been underestimated. Furthermore, AD appears to be more closely related to axonal loss, as demonstrated by spinal cord atrophy, than to demyelinating lesions.

Congenital myopathy with central cores and fingerprint bodies in association with malignant hyperthermia susceptibility.

A 26-year-old man had proximal weakness in the shoulder and the pelvic girdle since infancy. His sister, aged 16 years, presented a similar phenotype with more pronounced pelvic weakness. His muscle biopsy showed dense non-reducing inclusions which had a lamellar pattern at the ultrastructural level. These structures showed the typical features of fingerprint inclusions which were widely distributed in the fibers. Several central cores and other structural changes such as Z-line streaming were also observed. In view of the central cores, the male patient was investigated for malignant hyperthermia susceptibility. After exposure to halothane or caffeine, unusual intense contractures were observed on fiber preparations. The coexistence of central cores associated with fingerprint inclusions is suggestive of mixed congenital myopathy, which is in our case associated with malignant hyperthermia susceptibility.

Acute myelopathies: Clinical, laboratory and outcome profiles in 79 cases.

The main aetiologies of acute myelopathy (AM) are: multiple sclerosis, systemic disease (SD), spinal cord infarct (SCI), parainfectious myelopathy (PIM) and delayed radiation myelopathy (DRM). Although a large amount of data have been published for each individual aetiology, comparison studies are scarce. The aim of this study was to assess the various aetiological and outcome profiles of AM. We studied 79 cases: 34 (43%) in multiple sclerosis; 13 (16.5%) in SD; 11 (14%) in SCI; five (6%) in PIM; and three (4%) in DRM. Myelopathies were of unknown origin in 13 (16.5%) patients. We evaluated clinical, spinal cord and brain MRI, CSF and evoked potentials data at admission, MRI outcome at 6 months and clinical outcome at 12 months. A statistical comparison of clinical, laboratory and outcome data was only performed between multiple sclerosis, SD and SCI patients due to the small number of cases in the other groups. A motor deficit was more frequent in SD and SCI than in multiple sclerosis where initial symptoms were predominantly sensory (P < 0.001). Spinal cord MRI showed lateral or posterior lesions of less than two vertebral levels in multiple sclerosis, in contrast to SD and SCI, where lesions involved more vertebral levels and were centromedullar (P < 0.001). Brain MRI was most frequently abnormal in multiple sclerosis (68%), but was also abnormal in 31% of SD patients (P < 0.05). Oligoclonal bands in CSF were more frequent in multiple sclerosis than in SD (P < 0.001) and were never found in SCI. Clinical outcome at 12 months was good in 88% of multiple sclerosis cases, and poor or fair in 91% of SCI and 77% of SD. Aetiologies of AM may be differentiated on the basis of clinical, spinal cord and brain MRI, CSF and outcome data, and allow a probable diagnosis to be made in previously undetermined cases. These findings may have therapeutic implications for cases with a questionable diagnosis.

[Kjellin syndrome].

A previously healthy 30-year-old woman who had cognitive impairment since childhood suddenly developed progressive spastic paraparesis. Visual impairment and characteristic retinal macular spots supported the diagnosis of Kjellin syndrome. This disease, probably transmitted by autosomal recessive inheritance, is seldom observed in clinical practice. We describe the characteristics of Kjellin syndrome and the differential diagnosis, including other macular changes associated with spastic paraparesis.
