An autopsy case of acute multiple sclerosis (Marburg's type) during pregnancy

We report a case of a 9-month pregnant woman who presented acute psychiatric and neurological symptoms with extensive involvement of the white matter on MRI and no oligoclonal bands on CSF examination. Despite high doses of intravenous steroids, plasmapheresis and immunosuppressive drugs, a fatal outcome (coma) was noted 8 months later. Neuropathological examination confirmed the diagnosis of Marburg's type of multiple sclerosis showing sharp-edged lesions of demyelination, giant astrocytes, numerous macrophages and little perivascular inflammation. We discuss the definition and limits of the Marburg entity with reference to acute disseminated encephalomyelitis, impact of pregnancy, unusual MRI features, neuropathology and treatment.

Isoelectric focusing of CSF proteins and the future evolution of multiple sclerosis: a clinical follow-up

Summary A clinical follow-up covering a period of 5–10 years after onset was performed in 150 patients with optic neuritis or other potential onset symptoms of MS. Thin-layer isoelectric focusing had been used for the initial CSF-protein analysis. No evidence for a more probable alternative diagnosis appeared in 147 patients while a non-MS diagnosis was established in 3 patients. Among these 147 subjects the planned follow-up was accomplished in 131 patients, but not in 16. An evolution into clinically definite MS occurred in 59 subjects, in whom oligoclonal CSF immunoglobulin was found in 92%. Further clinical activity without spatial dissemination—i.e. lesser degrees of diagnostic probability for MS—were found in 35 patients in whom oligoclonal CSF immunoglobulin components were detected in 86%. Among the 131 patients with a complete follow-up, 45 remained free from further clinical activity; oligoclonal CSF immunoglobulin components occurred in 40% of these patients. The frequency of further clinical activity with or without spatial dissemination was significantly higher in subjects exhibiting oligoclonal CSF immunoglobulin components than in those without such changes.The initial part of the investigation was performed at the Department of Neurology, Karolinska Hospital, Stockholm, Sweden     

Cognitive forms of multiple sclerosis: Report of a dementia case

Cognitive impairment is now well documented in patients with multiple sclerosis (MS), and series of MS patients with predominant cognitive problems have been published recently. We report the observation of a female patient with severe cognitive presentation at the onset of MS, with dramatically demented evolution, and show MRI examination results. We discuss the published reports of primary cognitive types of MS.     

Effective treatment of chronically progressive multiple sclerosis with low-dose cyclophosphamide with minor side-effects

Summary Twenty-one multiple sclerosis (MS) patients with a chronically progressive course were treated with a low dose of cyclophosphamide (CY). The control group consisted of 21 MS patients with a chronically progressive course who received the standard treatment (ACTH or cortisone). The control group consisted of patients who preferred the standard therapy because of its beneficial effects. In contrast, the patients of the CY group wanted to try a new therapy because the standard therapy was not effective. Thus before starting the study the progression of the disease was faster in the CY group than in the standard therapy group. As regards age, sex and degree of disability, the two groups were comparable. For 20 of the 21 patients in the CY group the degree of disability (Kurtzke scale) remained stable over 1 year; for 2 of the 20 stable patients there was even an improvement. In the standard therapy group, 7 out of 21 patients were stable over 1 year, while 14 showed progressive disability. A quantitative neurological score at the beginning and 1 year after the therapy showed a nearly identical difference between the CY group and the control group. The changes of the patients' abilities in daily-life activities (which were observed and recorded by the nurses) were similar to the Kurtzke scale data obtained by the physicians. The beneficial effect of CY in chronically progressive MS was thus highly significant (P<0.001). The side-effects of low-dose CY were fewer than those of ACTH.     

Sexual function in multiple sclerosis. A 5-year follow-up study

Sexual dysfunction is known to occur in multiple sclerosis (MS). The purpose of the study is to describe the change in sexual function and symptoms in a longitudinal study. Forty-nine patients (27 females, 22 males) with definite MS were interviewed and examined with 5 years interval. The number of patients with sexual dysfunction increased significantly (p=0.009) and involved females and males equally. Males usually had 1 or two symptoms of sexual dysfunction, while females frequently had 2 or more symptoms. It is concluded that the risk of sexual dysfunction increases over time. Further studies in treatment possibilities are needed.The study has received financial support from a number of funds via the Danish Multiple Sclerosis Society, Bikubenfonden and Fonden for sclerose-ramte paa Fyn. The study has been presented in preliminary forms at the 3rd Meeting of the European Neurological Society, Lausanne 27/6–1/7 1992 and the 10th ECTRIMS Congress; Athens 3-5/11 1994.     

Neuropsychological assessment in multiple sclerosis: a follow-up study with magnetic resonance imaging

Summary Nineteen moderately impaired patients with clinically definite multiple sclerosis and an initially relapsing-remitting course were included in a neuropsychological and magnetic resonance imaging (MRI) follow-up study. The average test/re-test interval was about 2 years. The neuropsychological findings were indicative of a very mild overall impairment; the patients, as a group, showed no evidence of cognitive deterioration in the follow-up period. A numerical estimation of the severity of cerebral demyelination shown by MRI did not indicate a significant change. No correlation between cognitive performance variations and MRI changes was found.

Choreoathetosis in multiple sclerosis

Extrapyramidal symptoms are extremely rare in multiple sclerosis. We examined a patient with a ten year history of multiple sclerosis, who developed choreoathetoid movements of both upper extremities. To our knowledge this is the second case report of this association.     

Trauma and multiple sclerosis

Summary An obligatory event in the pathogenesis of the multiple sclerosis plaque appears to be an increase in the permeability of the blood-brain barrier. Neuropathological observations of the brain of persons suffering from concussion after relatively minor head injury, as well as of animals subjected to experimental brain injury, have shown that alterations of the blood-brain barrier constitute a common result of such trauma. It is postulated that the alterations of the blood-brain barrier secondary to trauma of the brain or spinal cord of patients with already established multiple sclerosis may result in an exacerbation or recurrence of a previously symptomatic plaque, in the appearance of symptoms from a silent lesion, or in the formation of a new plaque in such an area of selected vulnerability. In other persons injury to the nervous system may cause the development of multiple sclerosis plaques in the previously damaged areas when the disease has its onset after the trauma. There is no evidence to support the idea that trauma ever causes multiple sclerosis.     

An association between multiple sclerosis and type I diabetes mellitus

Summary We report five patients who had multiple sclerosis (MS) associated with type I diabetes mellitus (TODM). Examination of the Israeli National Neurological Disease Register revealed the prevalence of TODM among 334 MS patients under the age of 30 years to be 8.98 per 1,000. This is significantly higher than the prevalence of TODM in the general population of Israel for the same age group, which is 0.095 per 1,000. MS and TODM share clinical, epidemiological and immunological features, and both diseases have a target site that is neuroectodermal in origin. The association between these two putative autoimmune diseases may suggest a similar pathogenetic mechanism.

Short-term intensive cyclophosphamide treatment in progressive multiple sclerosis

14 patients with chronic progressive multiple sclerosis, selected in a preliminary uncontrolled trial, were given a short course of intensive cyclophosphamide therapy, which was discontinued when the leukocyte count fell to 3000 cu.mm. 5 patients dropped out because of severe side effects. At 1 year follow-up were neurologically unchanged since admission to the trial; 4 remained stable at 2 years. The lack of clinical improvement, the high frequency of side effects and the proven oncogenicity of cyclophosphamide led us to discontinue the trial.

Sommario 14 pazienti con SM definita e con forma cronica severamente progressiva sono stati trattati con un ciclo a breve termine e ad alto dosaggio di ciclofosfamide (400 mg/die), associata a cortisone (100 mg/die). L'immunosoppressione è stata considerata efficace quando è stata raggiunta una leucopenia di 3.000/mmc e a quel momento il farmaco è stato interrotto. 5 pazienti non hanno terminato il trattamento per la comparsa di gravi effetti collaterali. Dopo 1 anno di follow-up tutti i pazienti erano stazionari rispetto all'ingresso; 4 pazienti hanno terminato il secondo anno di follow-up e in essi la malattia si è mantenuta in fase di stabilizzazione. Nonostante questo, l'assenza di miglioramenti clinici, l'alta frequenza di effetti collaterali, la dimostrata oncogenicità della ciclofosfamide non ci incoraggia a continuare la sperimentazione.

     

Hypermetabolism in multiple sclerosis patients

Hypermetabolism, which can lead to wasting syndrome, is well recognized in diseases such as AIDS, cancer, rheumatoid arthritis, sepsis and burns. In these conditions proinflammatory cytokines are thought to be essentially involved. In experimental allergic encephalitis (EAE), which is regarded as an animal model of multiple sclerosis (MS), wasting syndrome and elevated levels of cytokines have also been reported. The aim of this study was to investigate whether hypermetabolism does occur in MS patients. After a 3-day standard diet the basal metabolic rate (BMR) was measured by indirect calorimetry in 20 MS patients and 10 healthy controls. Body composition was assessed using an impedance analyser and lean body mass (LBM) was calculated. Other metabolic disturbances and infectious disease were ruled out by clinical examination and various laboratory tests. Tested by analysis of variance (ANOVA), the BMR corrected for LBM was increased by an average of 6% in the patients group (p < 0.05) as compared to the controls. As far as we know this is the first study demonstrating the presence of hypermetabolism in MS.     

Rehabilitation challenges in multiple sclerosis

While current immunomodulating drugs aim to reduce multiple sclerosis (MS) exacerbations and slow disease progression, rehabilitation aims to improve and maintain the functional abilities of patients in the face of disease progression. An increasing number of journal articles are describing the value of the many rehabilitation interventions that can be used throughout the course of the disease, from the initial symptoms to the advanced stages. An integrated team of healthcare professionals is necessary to address a myriad of problems to reduce impairments, disabilities, and handicaps. The problems may be related to fatigue, weakness, spasticity, mobility, balance, pain, cognition, mood, relationships, bowel, bladder, sexual function, swallowing, speech, transportation, employment, recreation, and activities of daily living (ADL) such as dressing, eating, bathing, and household chores. The team can help prevent complications and secondary disabilities, while increasing patient safety. Improving neurologically related function, maintaining good relationships, and feeling productive and creative adds enormously to the quality of life of people with MS and their families. Rehabilitation is more than an ‘extra’ service that is given after medical therapies; it is an integral part of the management of the diverse set of problems encountered throughout the course of the disease. An interdisciplinary team may have many members, including physicians, nurses, physical therapists, occupational therapists, speech and language pathologists, psychotherapists, social workers, recreational therapists, vocational rehabilitation therapists, patients, families, and other caregivers.     

A case of multiple sclerosis triggered by organic solvents

The neurotoxicity of organic solvents has long been recognized. Some are used as anesthetic agents, others in various industries. Their acute effect has been well documented since the nineteenth century, but more recently they have become notorious as the cause of addiction to glue sniffing. They may alter the immune system by causing lymphopenia, impairing phagocytosis and decreasing the level of serum complement, as well as altering the impermeability of the blood-brain barrier and leading to the appearance of white matter lesions in the brain. The following case study explores the possible role of organic solvents in the pathogenesis of multiple sclerosis.

Western and Asian features of multiple sclerosis in Mexican Mestizos

OBJECTIVES: The objective of this study was to compare the clinical expression of MS in Mexican Mestizos with that of patients of European or Asian descent; as well as to compare the annual frequency of new cases with that observed in the previous decades. PATIENTS AND METHODS: All patients with diagnosis of definite MS seen at the National Institute of Neurology and Neurosurgery of Mexico from January 1993 to December 2003 were studied (n=312). Sociodemographic and clinical characteristics were compared with reports of patients from either Western or Asian origin; the long-term disability score was analyzed according to gender, age of onset of MS and the initial symptom. RESULTS: The clinical expression of MS in Mexican Mestizos shares some characteristics with both, Asian and Western forms of MS indicating that the genetic composition of Mexican Mestizos participates in the clinical expression of the disease. Also, at the prevalence date, the mean age of patients and the duration of the disease were lower in our patients than in MS patients from endemic countries suggesting a true increasing incidence in recent times, rather than only improved case ascertainment. CONCLUSIONS: Clinical expression of MS in Mexican Mestizos shows the coexistence of some features common in European and in Asian cases.
