Clinical and MRI assessment of disease activity in patients with multiple sclerosis after influenza vaccination.

We investigated the possible effects of influenza vaccination on disease activity in multiple sclerosis (MS). Six patients were evaluated clinically during the year preceding and the year following influenza vaccination. Gadolinium-enhanced magnetic resonance imaging (Gd-MRI) was performed one day before and at days 15 and 45 after vaccination. Cumulatively, we did not observe increases in clinical or MRI disease activity following vaccination, with the exception of one case. This was the patient with the highest clinical disease activity during the year preceding vaccination. These results support and supplement previous observations, indicating that influenza vaccination is a safe procedure in multiple sclerosis. Nevertheless, it should be used with caution in patients with active/progressing disease.

Fatigue in MS is associated with specific clinical features.

INTRODUCTION: fatigue is a common and disabling symptom in multiple sclerosis (MS). In this study we evaluated if fatigue is associated with different demographic and clinical features of MS. MATERIAL: A survey was performed on 507 consecutive patients affected by clinically definite MS referred to our centre between January 1 and December 31, 1993. During the examination patients were asked to answer a brief fatigue questionnaire. To evaluate the probability of the occurrence of fatigue in association with several covariant factors (age, sex, duration, disease form, disease severity, month of examination, functional sub-systems on the expanded disability status scale (EDSS), a logistic regression analysis was performed. RESULTS: we confirmed that fatigue is common in MS, recorded in 53% of patients. Patients affected by a more severe disability, by progressive MS, both primary and secondary, with an older age at examination, and assessed during spring, had a significantly higher risk of fatigue. Sex was not associated with the occurrence of fatigue. When the single items of EDSS were considered, we found that fatigue is also associated with the occurrence of cerebellar, sphincteric, pyramidal and sensitive signs, but not with brain stem, visual and cognitive impairment. CONCLUSION: fatigue in MS is more frequent in association with specific clinical features.

A controlled study of potential risk factors preceding exacerbation in multiple sclerosis.

A wide variety of potential risk factors for acute exacerbations in multiple sclerosis were evaluated in a one year case-control study. Eighty nine consecutive patients with clinically definite multiple sclerosis and relapsing remitting course presenting with a relapse between January and December 1992 were compared with patients matched for age, sex, and degree of disability, who did not experience clinical exacerbations during the same period. Only potential risk factors occurring in the three months preceding the interview were considered patients. Relapsing patients reported no significant increase in the frequency of any risk factor in the three month period before exacerbation compared with the control group. These results suggest that most relapses are not preceded by the conditions commonly considered as risk factors.

Human recombinant interferon beta in the treatment of relapsing-remitting multiple sclerosis: preliminary observations.

An open comparative, randomized trial with recombinant human interferon beta (r-hIFN-beta) involving 72 patients with clinically definite and/or laboratory-supported relapsing-remitting MS is in progress at the University 'La Sapienza' and at the S. Camillo Hospital of Rome. After a 6 month period of clinical and magnetic resonance imaging (MRI) observation (baseline findings), patients are randomly assigned to one of two treatment groups receiving 3 or 9 MIU of recombinant human IFN-beta (r-hIFN-beta) self-administered by subcutaneous injection three times a week for 6 months. All patients are examined by MRI with and without gadolinium (Gd-DTPA) every 4 weeks for the entire duration of the study (12 months). The main aim of the study is to test the hypothesis that r-hIFN-beta may halt or slow the progression of the disease by showing a significant reduction in MRI activity. This will be achieved by comparing pre and post-treatment periods. As an additional clinical end point, the exacerbation rate during these two periods will be compared. This study began in June 1993 and the final analysis of MRI data is planned for the spring of 1995.

A controlled trial of mitoxantrone in multiple sclerosis: serial MRI evaluation at one year.

We present the results of a randomized double-blinded placebo controlled, multicenter trial, of low-dose mitoxantrone (MX), after one year, in 25 patients with relapsing-remitting multiple sclerosis, who had serial enhanced magnetic resonance imaging (MRI). Treatment groups were balanced for age, gender, duration of illness and neurological disability. Five of the 13 MX patients and 10 of the 12 placebo patients had exacerbations during treatment (p < 0.02). The mean change in the extended disability status scale was not significantly different between the MX and placebo treatment groups. Serial Gadolinium-DTPA enhanced MRI detected no significant difference between the MX treated and placebo groups in the mean total number of new, enlarging, or Gadolinium-DTPA enhancing lesions; there was a trend toward a reduction of new, enlarging and Gadolinium-DTPA enhancing lesions in MX patients. Despite this ameliorating effect, the results indicate that serial Gadolinium-DTPA enhanced MRI, performed over one year in a limited number of patients, could not provide conclusive evidence for a role of MX therapy in relapsing-remitting multiple sclerosis.

Depression in the early phase of MS: influence of functional disability, cognitive impairment and brain abnormalities.

This study investigated the relationship between depression, physical disability, cognitive deficit and brain abnormalities on magnetic resonance imaging (MRI) in patients with early MS. Eighteen relapsing-remitting MS patients were evaluated: depression was diagnosed according to DSM-III R and measured by the MMPI depression subscale, physical disability was assessed by using the Kurtzke Expanded Disability Status Scale (EDSS) and cognitive functions by means of an extensive neuropsychological test battery. A neuroradiologist blinded to clinical findings quantified cerebral lesion on MRI. Weighted brain area lesion score were developed according to number and size of cerebral lesions. On the basis of DSM-III criteria, six patients were classified as having major depression, seven patients had minor depression and five patients were without depressive symptoms. No significant differences were found among the three groups on both neuropsychological performances and weighted MRI lesion scores. However patients with major depression exhibit greater physical disability than the other MS subgroups. A significant correlation was found between MMPI depression subscale and physical disability. This study suggests that at least in the early phase of MS, depression appears more related to the physical disability than to the severity of pathological brain involvement.

Anterior corpus callosum atrophy and verbal fluency in multiple sclerosis.

To determine whether different portions of the corpus callosum (CC) are responsible for transferring the information of specific cognitive modalities, eighteen females with relapsing-remitting Multiple Sclerosis (MS) were studied using neuropsychological procedures and Magnetic Resonance Imaging (MRI). Measures of both anterior and posterior CC areas were obtained in patients with MS as well as in eighteen age and sex matched healthy controls. MRI scans were additionally analyzed for each patient in order to evaluate the extent of demyelinating lesions in both periventricular and subcortical areas. Patients with MS exhibited a significant decrease in both the anterior and posterior CC areas compared with normal subjects. The results of statistical analysis showed that, even when the effect of demyelinating lesions was taken into account within a regression equation, the atrophy of anterior CC area strongly affected the performance on verbal fluency task. These data emphasize the importance of the anterior CC area for the interhemispheric transfer of cognitive information associated with verbal fluency.

Circadian variation in the onset of acute cerebral ischemia: ethiopathogenetic correlates in 80 patients given angiography.

In a continuous series of 80 acute ischemic hemispheric strokes, the onset of symptoms was between 6:01 a.m. and noon in 45% of cases, between noon and 6:00 p.m. in 22.5%, between 6:01 p.m. and midnight in 31.25%, and between midnight and 6:00 a.m. in 1.25% (p less than 0.0001). By means of angiography and computerized tomography, and by detection of arterial and cardiac sources of emboli, four stroke subtypes were identified. Embolic and thrombotic strokes had their most frequent onset between 6:01 a.m. and noon (45% and 71%, respectively), whereas strokes of unknown origin and lacunar strokes were randomly distributed between 6:01 p.m. and midnight. The morning activation of the catecholaminergic system can account for this pattern of circadian onset of ischemic stroke.

Effect of stress on cardiovascular regulation in neurological diseases with dysautonomia.

Ten patients with Multiple Sclerosis (MS) and ten with Myotonic Dystrophy (MD) underwent an evaluation of cardiovascular reflexes by classic tests, tilt table test and mental stressors. Sympathetic and parasympathetic changes were detected by classical tests in MS patients. Mental stressors appeared able to reveal blood pressure control impairment in MD patients. Lower differential blood pressure was observed during mental stressors administration in MS with brainstem lesions at MRI.

Controlled clinical trials in stroke.

Reasons for the unsatisfactory number and reliability of most trials on the pharmacological treatment of acute cerebral ischemia are reviewed, focusing mainly on the clinical aspects of the issue. The opportunity of early intervention, supported by current pathophysiological hypotheses, is recognized. Past and recent Italian trials on ischemic stroke patients evaluated and treated within the first 6 h from onset are reported, also mentioning the results of a study including early cerebral angiography and SPECT (Single Photon Emission Computed Tomography). Early fibrinolytics associated to brain protecting agents are regarded as the future choice in clinical trials of acute cerebral ischemia.

24-month follow-up of multiple sclerosis patients treated with cyclophosphamide.

15 patients with remitting-progressive multiple sclerosis received a course of intravenous cyclophosphamide followed by a booster dose every 60 days for 2 years. There were no severe short or medium term side effects. Half of the patients presented clinical stabilization and substantially unchanged Kurtzke rating at 2 year follow-up. Since the aim was stabilization only, our findings argue for continuation of the study in young patients with very short shift.

Lead poisoning during heroin addiction.

We describe the case of a young man addicted to heroin with the clinical pattern of symmetrical brachial neuropathy, without other neurological involvement. Lead poisoning was detected and chelating therapy induced a marked improvement of the clinical symptoms. The possible toxic effect of heavy metals in the pathogenesis of brachial and lumbar plexopathies during heroin addiction has previously been suggested by other authors, but never detected.

Evolution and severity markers in 233 MS patients.

Clinical data of 233 patients (202 definite and 31 probable MS) have been examined in relation to the following prognostic indicators: sex, age at onset, poussè frequency, interval between the first two relapses, initial symptomatology. Regression analysis technique and covariate analysis have been used versus the latest Expanded Disability Status Scale of each patients. Onset at younger age and a longer interval between the first two episodes have resulted statistically significant for a more favourable prognosis. The shift from a remitting toward a progressive course appears to happen within the first five years in 60% of the cases.
