Hormonal management of migraine at menopause

Monoclonal anti-CGRP antibodies in post-menopausal women: a real-life study

INTRODUCTION

Migraine usually ameliorates after menopause. However, 10-29% of women still experience migraine attacks after menopause, especially if menopause is surgical. The use of monoclonal antibodies against the calcitonin gene-related peptide (CGRP) is changing the landscape of migraine treatment. This study aims to explore the effectiveness and safety of anti-CGRP monoclonal antibodies in women in menopause.

METHODS

Women affected by either migraine or chronic migraine and treated with an anti-CGRP monoclonal antibody for up to 1 year. Visits were scheduled every 3 months.

RESULTS

Women in menopause displayed a similar response compared to women of childbearing age. Among women in menopause, the women experiencing surgical menopause seemed to exhibit a similar response compared to the ones experiencing physiological menopause. Erenumab and galcanezumab displayed similar effectiveness in women in menopause. No serious adverse events were registered.

DISCUSSION

The effectiveness of anti-CGRP monoclonal antibodies is almost the same between women in menopause and women of childbearing age, without appreciable differences between the different antibodies.

Role of Estrogens in Menstrual Migraine

Migraine is a major neurological disorder affecting one in nine adults worldwide with a significant impact on health care and socioeconomic systems. Migraine is more prevalent in women than in men, with 17% of all women meeting the diagnostic criteria for migraine. In women, the frequency of migraine attacks shows variations over the menstrual cycle and pregnancy, and the use of combined hormonal contraception (CHC) or hormone replacement therapy (HRT) can unveil or modify migraine disease. In the general population, 18–25% of female migraineurs display a menstrual association of their headache. Here we present an overview on the evidence supporting the role of reproductive hormones, in particular estrogens, in the pathophysiology of migraine. We also analyze the efficacy and safety of prescribing exogenous estrogens as a potential treatment for menstrual-related migraine. Finally, we point to controversial issues and future research areas in the field of reproductive hormones and migraine.

Acute and Preventive Management of Migraine during Menstruation and Menopause

Migraine course is influenced by female reproductive milestones, including menstruation and perimenopause; menstrual migraine (MM) represents a distinct clinical entity. Increased susceptibility to migraine during menstruation and in perimenopause is probably due to fluctuations in estrogen levels. The present review provides suggestions for the treatment of MM and perimenopausal migraine. MM is characterized by long, severe, and poorly treatable headaches, for which the use of long-acting triptans and/or combined treatment with triptans and common analgesics is advisable. Short-term prophylaxis with triptans and/or estrogen treatment is another viable option in women with regular menstrual cycles or treated with combined hormonal contraceptives; conventional prevention may also be considered depending on the attack-related disability and the presence of attacks unrelated to menstruation. In women with perimenopausal migraine, hormonal treatments should aim at avoiding estrogen fluctuations. Future research on migraine treatments will benefit from the ascertainment of the interplay between female sex hormones and the mechanisms of migraine pathogenesis, including the calcitonin gene-related peptide pathway.

Recommendations for the treatment of migraine attacks - a Brazilian consensus

ABSTRACT In this article, a group of experts in headache management of the Brazilian Headache Society developed through a consensus strategic measurements to treat a migraine attack in both the child and the adult. Particular emphasis was laid on the treatment of migraine in women, including at pregnancy, lactation and perimenstrual period.

Treatment of status migrainosus by general anesthesia: a case report

BACKGROUND AND OBJECTIVES

The status migrainosus is a complication of migraine characterized by severe headache for more than 72h that did not respond to treatment, with risk of stroke and suicide. Researches on treatment are directed to drugs that stimulate GABA receptors; propofol and isoflurane act on sub-GABAa receptors and theoretically could be interesting. The first has been the subject of research in severe migraine. Opioids are employed in pain, and its use in chronic headache is debatable, but these agents are employed in acute cases. The goal is to present a case of refractory status migrainosus in that we decided to break the pain cycle by general anesthesia.

CASE REPORT

Female patient, aged 50 years, with status migrainosus, in the last five days with visits to the emergency department, medicated parenterally with various agents without result. Without comorbidities, dehydrated, described her pain as "well over 10" in Visual Numeric Scale (VNS). After consulting the literature, and given the apparent severity of the condition, we opted for a general anesthesia: induction with fentanyl, propofol, and vecuronium and maintenance with isoflurane and propofol for two hours. Following the treatment, in the postanesthetic recuperation (PAR), the patient related her pain as VNS 3, and was released after five hours with VNS 2. Subsequently, her preventive treatment was resumed.

CONCLUSION

Status migrainosus is a rare disabling complication and anesthetics have been the subject of research in its treatment; the option for general anesthesia with agents that stimulate GABA receptors, propofol and isoflurane, in association with fentanyl, proved effective and should encourage new research.

Sex-related differences in migraine

This paper reviews sex-related differences in migraine epidemiology, symptoms, natural history and co-morbid disorders. Migraine is more than twice as common in females as in males, and women experience more frequent, longer lasting and more painful attacks, have more disability and a risk of transition from episodic to chronic migraine greater than men, but the mechanisms behind these differences are still poorly understood. The role of sex hormones, genes, and the differences in brain function and structure are discussed. Finally, we evaluate the many gender-related questions about treatment of migraine in women. In future research data should be analyzed separately for men and women to ensure that differences between the sexes could be identified.

Health issues for menopausal women: the top 11 conditions have common solutions

Multiple health issues affect women throughout the life course differently from men, or do not affect men at all. Although attention to women's health is important in all stages in life, health among middle-aged and elderly women has not received sufficient attention by scientists and policy-makers. Related to the menopausal transition and the experiences accumulated until that age, many diseases occur or further develop in middle-aged and elderly women. To improve women's quality of life and guarantee a long-lasting and active role for middle-aged and elderly women in society, prevention of chronic diseases and disability is a key aspect. In this manuscript we give an overview of the major health issues for peri- and post-menopausal women, we summarize risk factors and interventions to improve menopausal health. Based on the available scientific literature and the global burden of disease endeavor, we have selected and herein describe the following top 11 key health issues, selected in terms of burden exerted in women's mortality, morbidity, disability and quality of life: cardiovascular disease, musculoskeletal disorders, cancer, cognitive decline and dementia, chronic obstructive pulmonary disease, diabetes mellitus, metabolic syndrome, depression, vasomotor symptoms, sleep disturbances and migraine.

Sex matters: evaluating sex and gender in migraine and headache research

Significant sex differences exist in migraine and other headache disorders. Several hypotheses have been proposed to explain these differences, including fluctuations in sex hormones and receptor binding, genetic factors, differences in exposure to environmental stressors, as well as differences in response to stress and pain perception; but how valid are some of these findings and can we improve the quality of research in this field? It is notable that the preponderance of animal pain studies use male subjects to study a predominantly female disorder. Furthermore, with respect to headache and migraine sex differences, limited data have been derived from animal models. Additionally, although sex differences (based on the categorization of male vs female) may be more routinely evaluated in clinical headache research than in the basic science research, greater attention to potential differences across the life cycle of women (ie, premenopausal vs postmenopausal differences) and menstrual cycle is warranted. In this manuscript we define the differences between "sex" and "gender" and highlight the importance of their application and use in headache research. The enhanced recognition and implementation of attention to sex differences throughout the hormonal and life-cycle phase in both human and animal research will only help to strengthen and further our understanding of migraine and may help guide the direction of future headache research.

Transdermal hormonal therapy in perimenstrual migraine: why, when and how?

Experimental and clinical evidence is strongly in favor of a role for estrogens in migraine. It is clear that estrogen fluctuations represent trigger factors for the attacks, while the resolution of these fluctuations (menopause) may be associated to the remission or, conversely, to the worsening of the disease. However, the exact mechanisms and mediators underlying the effects of estrogens in migraine are largely unknown. The exact mechanisms and mediators underlying the effects of estrogens in migraine are largely unknown. In this review, we summarize clinical and preclinical data that are relevant for the role of estrogens in migraine and we discuss how estrogen modulation can be exploited positively to improve hormonal-related migraine.

Migraines and perimenopause: helping women in midlife manage and treat migraine

Migraine is more common in women than men, with lifetime prevalence rates between 15 percent and 26 percent for women. The World Health Organization ranks migraine as 12th among all causes of years lived with disability in women. This article reviews diagnostic criteria for migraine with and without aura, the impact of fluctuating hormones in perimenopause on the experience of migraine and medication and nonmedication approaches to managing migraine.

Neuroendocrine aspects of migraine in women

Migraine is a complex disabling disease influenced mainly by age and gender during the life span. Neuroendocrine events related to reproductive stages and to the menstrual cycle may cause significant change in the clinical pattern of migraine over time, as a consequence of failure in adaptation higher in women than in men. Indeed, the individual threshold of vulnerability to manifest migraine is modulated by hormonal fluctuations naturally occurring throughout the menstrual cycle and at the time of reproductive transitions. In the present short review, the role of endogenous estrogen at the level of brain circuitries which are involved in multiple cellular, neurochemical and neurophysiological processes associated with migraine will be summarized in the context of reproductive milestones. In addition, some clues to recognize hormonally sensitive women on the basis of their migraine history, i.e. onset, association with menstruation or premenstrual syndrome, course during pregnancy and menopause, will be discussed in order to expand the knowledge of reproductive endocrinology in the management of migraine in women.

Hormonal manipulation strategies in the management of menstrual migraine and other hormonally related headaches

Menstrual migraine and other hormonally related headaches are common in women. Falling estrogen levels or estrogen withdrawal after periods of sustained higher levels can trigger migraine. It makes sense to target this trigger for management of hormonally related headaches, particularly when nonhormonal strategies have been unsuccessful. Decision making regarding the use of hormonal contraception and menopausal hormone therapy is complex and commonly driven by other factors, but hormonal manipulation can potentially improve the course of migraine. Providers caring for migraineurs are appropriately concerned about stroke risk. Estrogen-containing hormonal contraceptives are relatively contraindicated for women who have migraine with aura. Postmenopausal hormone therapy is acceptable for women with a history of migraine. For these women, transdermal estradiol is recommended. Estrogen replacement is important for women who undergo an early menopause, whether natural or induced. Practical strategies for hormonal manipulation in the management of migraine and other hormonally related headaches are presented.

Relationship between lymphocytes, IL2 and the hormones E2, LH, PRG and FSH in menopausal and postmenopausal women

PROBLEM  In this baseline study, our aim is to show the relationship of parameters and gonad hormones in menopausal and postmenopausal women. METHOD  Blood samples were taken from menopausal and postmenopausal women (12-14 months and ≥10 years, respectfully, since their last menstruation). Adolescents aged 13.7 ± 0.7 were used as controls. Hormones were measured by ELISA and percentages of CD45, CD4, CD8, CD3, CD19, IL-2, CD25 and HLA-DR were measured by flow cytometry. RESULTS Both groups showed an increase in the percentage of CD3, CD4 and CD8. Levels of CD19 were significantly lower in the postmenopausal group. However, changes in immunologic parameters during menopause were less marked than the hormonal changes observed in these groups. Most of the correlations LH × CD3 (-ve), LH × IL2R (-ve) and E2 × CD19 (+ve) suggesting how menopausal women with particularly high LH or low E2 levels may be affected. Only CD3 and HLA-DR correlated with the hormonal changes in the postmenopausal group. IL-2 levels were high in the menopausal group and low in the postmenopausal group; however, no correlation was observed. DISCUSSION  Menopause is characterized by increased levels of IL-2, which has critical immune-modulatory effects. These changes may be related to the overall hormonal change process observed during menopause.

Migraine headache and ischemic stroke risk: an updated meta-analysis

BACKGROUND

Observational studies, including recent large cohort studies that were unavailable for prior meta-analysis, have suggested an association between migraine headache and ischemic stroke. We performed an updated meta-analysis to quantitatively summarize the strength of association between migraine and ischemic stroke risk.

METHODS

We systematically searched electronic databases, including MEDLINE and EMBASE, through February 2009 for studies of human subjects in the English language. Study selection using a priori selection criteria, data extraction, and assessment of study quality were conducted independently by reviewer pairs using standardized forms.

RESULTS

Twenty-one (60%) of 35 studies met the selection criteria, for a total of 622,381 participants (13 case-control, 8 cohort studies) included in the meta-analysis. The pooled adjusted odds ratio of ischemic stroke comparing migraineurs with nonmigraineurs using a random effects model was 2.30 (95% confidence interval [CI], 1.91-2.76). The pooled adjusted effect estimates for studies that reported relative risks and hazard ratios, respectively, were 2.41 (95% CI, 1.81-3.20) and 1.52 (95% CI, 0.99-2.35). The overall pooled effect estimate was 2.04 (95% CI, 1.72-2.43). Results were robust to sensitivity analyses excluding lower quality studies.

CONCLUSIONS

Migraine is associated with increased ischemic stroke risk. These findings underscore the importance of identifying high-risk migraineurs with other modifiable stroke risk factors. Future studies of the effect of migraine treatment and modifiable risk factor reduction on stroke risk in migraineurs are warranted.
