Migraine in Multiple Sclerosis

Use of Calcitonin Gene-Related Peptide Monoclonal Antibodies for the Treatment of Migraines in Individuals With Multiple Sclerosis

BACKGROUND

Migraines are a common comorbidity and source of disability in patients with chronic inflammatory diseases like multiple sclerosis (MS). Recently, therapeutic agents for episodic and chronic migraine known as calcitonin gene-related peptide (CGRP) inhibitors have shown to effectively control migraine attacks and improve quality of life in the general population. This study explored the use of these novel agents in individuals with comorbid MS.

METHODS

This was a retrospective, population-based cohort study at the University of South Florida's neurology clinic; it evaluated individuals with both MS and migraine.

RESULTS

A total of 27 individuals with MS and chronic or episodic migraine who received treatment with a CGRP monoclonal antibody were identified. Of these, 63% reported a reduction in their migraine frequency of greater than 75%. Concurrent use of a disease-modifying therapy (DMT) for MS occurred in 82% of patients, and in 37% of these, the DMT used was also a monoclonal antibody. Adverse effects from CGRP monoclonal antibodies were mild and occurred in only 11% of patients, and no patient experienced worsening of their MS symptoms during cotreatment over the duration of the study.

CONCLUSIONS

Our study showed a significant reduction in migraine frequency and a favorable adverse event profile for individuals with comorbid MS who took CGRP monoclonal antibodies and experienced no worsening of MS symptoms. In individuals with MS, CGRP monoclonal antibodies seem to be a safe and effective therapy for episodic or chronic migraine.

Cerebral Venous Sinus Thrombosis induced By Hypercoagulation in Patient With Systemic Lupus Erythematosus: A Case Report and Literature Review

Introduction

Systemic lupus erythematous (SLE) are autoimmune diseases and cerebral venous sinus thrombosis (CVST) is coincidence regarding hypercoagulable condition of both diseases. The presence of both diseases in the same patient is rare, which suggests a relative incompatibility between these diseases.

Case Presentation

I report a female case with Systemic Lupus Erythematosus history, aged 27 years, with blurred vision, diplopia, severe headache, numbness and progressive right hemiparesis in 2 weeks. There was narrowing caliber at left transversus and right sigmoid sinus in magnetic resonance venography. She showed improvement in vision, numbness, headache and motor strength in right extremities after receiving pulse dose of corticosteroid for three days.

Conclusion

The distinction between SLE and CVST is a diagnostic challenge for the neurologist, and the presence of both diseases should be considered in patients with clinical neurologic manifestations who present with typical systemic manifestations of SLE and CVST. Neurogenic inflammation can induce disorders of the blood vessel wall (endothelium) that cause hypercoagulability and changes in acute vascular conditions can occur consisting of intraluminal platelet aggregation, thrombosis and also can cause total cerebral thrombotic venous or venular occlusion in SLE patients.

Headache and immunological/autoimmune disorders: a comprehensive review of available epidemiological evidence with insights on potential underlying mechanisms

Several lines of evidence support a role of the immune system in headache pathogenesis, with particular regard to migraine. Firstly, alterations in cytokine profile and in lymphocyte subsets have been reported in headache patients. Secondly, several genetic and environmental pathogenic factors seem to be frequently shared by headache and immunological/autoimmune diseases. Accordingly, immunological alterations in primary headaches, in particular in migraine, have been suggested to predispose some patients to the development of immunological and autoimmune diseases. On the other hand, pathogenic mechanisms underlying autoimmune disorders, in some cases, seem to favour the onset of headache. Therefore, an association between headache and immunological/autoimmune disorders has been thoroughly investigated in the last years. The knowledge of this possible association may have relevant implications in the clinical practice when deciding diagnostic and therapeutic approaches. The present review summarizes findings to date regarding the plausible relationship between headache and immunological/autoimmune disorders, starting from a description of immunological alteration of primary headaches, and moving onward to the evidence supporting a potential link between headache and each specific autoimmune/immunological disease.

Headache and Its Management in Patients With Multiple Sclerosis

PURPOSE OF REVIEW

The purpose of this review was to discuss the prevalence, impact, pathophysiology, and treatment of headaches (H/As) in patients with multiple sclerosis (MS).

RECENT FINDINGS

Headaches and multiple sclerosis are more common in women than in men with the ratio of female to male being 3:1. It is not entirely clear if there is a correlation or an incidental comorbidity of two neurological conditions. A review of the literature shows a variable prevalence of H/As in MS patients. Using the International Classification of Headache Disorders (ICHD) criteria, the primary type of H/As, especially migraine, is the most common type seen in patients with MS. One of the theories of the pathophysiologic mechanisms of migraine in MS patients is inflammation leading to demyelinating lesions in the pain-producing centers in the midbrain. Secondary H/As due to MS medications such as interferons are also frequently present. H/As can be a cause for significant comorbidity in patients with MS. The treatment of H/As in patients with MS should be addressed in the same fashion as in the non-MS population, which is a combination of pharmacological and non-pharmacological methods. Preventive medicines for the H/As should be carefully selected because of their side effect profiles. Acute attacks of migraines can be treated with medications such as triptans. Patients with MS who have migraine H/As should be educated about the phenomenon of overuse H/As, keeping headache journals, avoiding stress, and monitoring sleeping habits. The presence of depression in patients with MS and migraine affects quality of life (QOL) and should also be addressed for better outcomes.

Headache in the first manifestation of Multiple Sclerosis - Prospective, multicenter study

Objectives

Multiple sclerosis (MS) is the most frequent immune-mediated inflammation of the central nervous system that can lead to early disability. Headaches have not been considered as MS-related symptoms initially, whereas higher prevalence rates were reported since 2000. Postmortem histological analyses of MS patients' brains revealed lymphoid follicle-like structures in the cerebral meninges which suggest a possible pathophysiological explanation for the high headache prevalence in MS. The aim of this study was to evaluate headache characteristics during the first clinical event of MS.

Methods

In a prospective, multicenter study, 50 patients with the diagnosis of CIS or MS were recruited. All participants were screened for the presence of headache within the last 4 weeks with help of the Rostock Headache Questionnaire (Rokoko).

Results

Thirty-nine of fifty questioned patients (78%) reported headaches within the last 4 weeks. Most patients suffered from throbbing and pulsating headaches (25, 50%), 15 (30%) reported stabbing, 14 (28%) dull and constrictive headaches.

Conclusions

Headaches were prevalent in 78% of patients in our population with newly diagnosed CIS and MS. It is among the highest prevalence rates reported so far in patients with CIS or MS. Thus, headache, especially of a migraneous subtype, is a frequent symptom within the scope of the first manifestation of multiple sclerosis. If it were possible to define a MS-typical headache, patients with these headaches and with typical MRI results would be classified as CIS or early MS instead of radiologically isolated syndrome and treated accordingly with an immunomodulatory therapy.

Increased contrast enhancing lesion activity in relapsing-remitting multiple sclerosis migraine patients

Background and objectives

While the literature supports the idea that multiple sclerosis (MS) and migraine are related, the exact mechanism(s) of this association is not well understood. Observations of increased contrast enhancing (CE) lesion activity in individual MS patients suffering from migraine prompted us to determine a relationship between migraine and MRI outcomes in a large cohort of MS patients.

Methods

We included 509 MS and 64 clinically isolated syndrome (CIS) patients and 251 age- and sex-matched healthy individuals (HIs) who obtained 3 T MRI and were assessed for history of migraine. Number and volume of T2, T1 and CE lesions and brain volume measures were determined. The MRI findings were analyzed adjusting for key covariates and correcting for multiple comparisons.

Results

More MS (22.2%) and CIS (17.2%) patients had migraine, compared to HIs (14.6%, p = 0.067). More MS patients with migraine presented with CE lesions compared to those without (35.4% vs. 23.7%, p = 0.013). MS migraine patients had significantly increased number (p = 0.019) and volume (p = 0.022) of CE lesions compared to those without. In the regression analysis, MS migraine patients had an increased number of CE lesions (B = 1.242, p = 0.001), specifically those with relapsing–remitting disease course (B = 1.377, p = 0.001). No significant association of other MRI measures and migraine was found in MS and CIS patients or in HIs.

Conclusions

Our findings suggest an increased inflammatory pathobiology in MS patients with migraine headaches requiring possibly more frequent MRIs and also more efficient anti-inflammatory treatment.

Headache in multiple sclerosis: features and implications for disease management

The aim of this study was to investigate the variables affecting headache occurrence in patients with multiple sclerosis (MS). Seventy-two MS patients with comorbid headaches completed a 28-item questionnaire. This evaluation assessed each patient's demographics, headache description and modifying factors, social history, and impact on quality of life. Our patients reported a wide spectrum of headache presentations, characteristics, and resulting disability. We discuss the patterns in our data in the context of current hypotheses regarding headache and MS causality. In our patients, migraines with aura strongly correlated with MS exacerbations, suggesting that they might be useful as a marker for flare-up onset. Patients' pain descriptions varied based on their headache frequency, history, and relationship to MS progression. Due to the severity of headache in MS patients and resulting impact on their activities of daily living, a thorough analysis of headache presentation is warranted in such patients.

Increased risk of multiple sclerosis among women with migraine in the Nurses' Health Study II

BACKGROUND

The prospective Nurses' Health Study II (NHS-II), which enrolled over 116,000 female nurses, provides a unique opportunity to test the hypothesis of whether migraine is associated with multiple sclerosis (MS) and to explore the temporal aspects of the interrelationship.

OBJECTIVES

To calculate relative risk of MS among NHS-II participants with and without migraine and to estimate odds ratio (OR) of being diagnosed with migraine in women with and without pre-existing MS.

METHODS

Cox proportional hazards regression was used to estimate rate ratios and 95% confidence intervals (CIs) of being diagnosed with MS in women with and without pre-existing migraine adjusted for potential confounders. Multivariate adjusted ORs of being diagnosed with migraine in women with and without pre-existing MS were estimated using logistic regression.

RESULTS

The prevalence of migraine in women with MS at baseline (26%, p = 0.11) and those diagnosed with MS after enrolment (29%, p < 0.0001) was higher than in the non-MS cases (21%). The relative risk of developing MS in migraineurs was 1.39 times higher than in non-migraineurs (95% CI 1.10-1.77, p = 0.008). The absolute risk of developing MS in women migraineurs over a 15-year follow-up was 0.47% and among non-migraineurs 0.32%. The odds of being diagnosed with migraine was higher in women with pre-existing MS compared with those without MS, but did not reach statistical significance (OR = 1.57, 95% CI 0.97-2.52; p = 0.06).

CONCLUSIONS

Using a large, cohort of women-nurses, history of migraine was associated with an increased risk of MS. However, the difference in absolute risk of MS in migraineurs and non-migraineurs was small.
