Low adherence to the guideline for the acute treatment of migraine

The real-world use of triptans in the treatment of migraine is disappointing. Only 12% of the Danish migraine population purchased a triptan between 2014 and 2019, and only 43% repurchased a triptan after first prescription. The aim of the present study was to assess whether physicians and patients adhere to the therapeutic guideline on acute migraine treatment. We interviewed 299 triptan experienced participants with migraine and 101 triptan naïve participants with migraine from the Danish Migraine Population Cohort, using a semi-structured questionnaire. Descriptive statistical analyses were used to study the association with triptan use and the assessed factors. Among triptan naïve participants with migraine, 64% had consulted their general practitioner about their migraine, of whom only 23% received information about the possibility of triptan treatment. Among triptan experienced participants, 77% had only tried one type of triptan. Only 12% could recall they had been informed by their general practitioner to try each triptan three times before giving up. Twenty percent were informed to try three different triptans in total, if the first did not work. In disagreement with the guideline, participants who reported a low pain reduction by a triptan had only tried one type of triptan. Our study shows a low adherence to therapeutic guideline for the attack treatment of migraine. There is a need for better education of general practitioners regarding treatment of migraine. Future campaigns should aim to inform both the public and the general practitioner about antimigraine treatments

Genome-wide analysis of 102,084 migraine cases identifies 123 risk loci and subtype-specific risk alleles

Migraine affects over a billion individuals worldwide but its genetic underpinning remains largely unknown. Here, we performed a genome-wide association study of 102,084 migraine cases and 771,257 controls and identified 123 loci, of which 86 are previously unknown. These loci provide an opportunity to evaluate shared and distinct genetic components in the two main migraine subtypes: migraine with aura and migraine without aura. Stratification of the risk loci using 29,679 cases with subtype information indicated three risk variants that seem specific for migraine with aura (in HMOX2, CACNA1A and MPPED2), two that seem specific for migraine without aura (near SPINK2 and near FECH) and nine that increase susceptibility for migraine regardless of subtype. The new risk loci include genes encoding recent migraine-specific drug targets, namely calcitonin gene-related peptide (CALCA/CALCB) and serotonin 1F receptor (HTR1F). Overall, genomic annotations among migraine-associated variants were enriched in both vascular and central nervous system tissue/cell types, supporting unequivocally that neurovascular mechanisms underlie migraine pathophysiology.publishedVersionPeer reviewe

Health-Care Seeking Behavior and Treatment of Menstrual Migraine among Danish Women—A Social Media Study

An estimated 4–8% of all women, and 16–25% of women with migraine, have menstrual migraine (MM), which causes considerable disability, but is underdiagnosed and undertreated. We investigated the burden of disease, health-care seeking behavior, and treatment practices among women with MM, using social media. In 12 days, 6246 women answered an online survey, allowing for diagnosis of MM by the International Classification of Headache Disorders third edition (ICHD-3). In total, 47% had MM, 21% had non-menstrual migraine (nMM), and 15% had probable menstrual migraine (pMM). Among women with MM, 61% had missed out on school/work and 69% on family, leisure, or social activities in the last 3 months. Fifty-four percent had consulted a health-care practitioner about their MM, of whom thirty-seven percent had received information about medical treatment of MM. A total of 85% used medicine in connection with MM, either over-the-counter medication only (57%), prescription medication only (24%), or both. Social media offers an efficient and less expensive recruitment platform for population-based studies on MM and is a useful tool to raise public awareness about MM. Moreover, this study confirms the significant impact of MM on women’s everyday lives and the challenges it poses to their regular activities
