Migraine is a common type of headache and its most severe attacks are usually treated with triptans, the efficacy of which is extremely variable. Several SNPs in genes involved in metabolism and target mechanisms of triptans have been described. To define an association between genetic profile and triptan response, we classified a migrainous population on the basis of triptan response and characterized it for polymorphisms in the genes coding for monoamine oxidase A, G protein β3 and the cytochr ...[more]

Project description:Chronic migraine (CM) prevalence ranges around 1-5%. Most of these patients usually treat their acute attacks with triptans, whose efficacy is extremely variable. A genetic basis for migraine is evident and many susceptibility genes have been described, as well as gene polymorphisms possibly implied in therapy response. Several factors could be involved in the evolution of episodic migraine into a chronic form, such as natural history, psychiatric comorbidity, and the individual's response to therapy. During a study aimed at detecting connections between genotype and response to triptans administration, we characterized a CM population for polymorphisms in the genes coding for monoamine oxidase A, g-protein beta 3 and the cytochromes CYP3A4 and CYP1A2. Alleles and genotypes distributions were compared with known frequencies of healthy Caucasian populations. A significant association with CM was found for the long allele of monoamine oxidase A 30 bp VNTR and CYP1A2*1F variant. Such genomic analysis is part of an integrated platform able to evaluate different levels of metabolic pathways of drugs in CM and their influence in the chronicization process.

Project description:ObjectivesThe management of chronic migraine (CM) with Medication Overuse Headache (MOH) consists of withdrawal therapy, education on medications' use and prescription of prophylaxis. Little attention has been given to patients who fail in achieving a successful short-term outcome after withdrawal: we aim to describe predictors of failure.MethodsPatients with CM and MOH were enrolled at the Neurological Institute C. Besta of Milano, and included if they completed the three months follow-up. Withdrawal failure was defined as the situation in which patients either did not revert from chronic to episodic migraine (EM), were still overusing acute medications, or both did not revert to EM and kept overusing acute medications. Predictors of failure were addressed with a logistic regression, and for all variables, the longitudinal course in the two groups was described.ResultsIn 39, out of 137 patients, withdrawal was unsuccessful: the predictors included day-hospital-based withdrawal (OR: 2.37; 95% CI: 1.06-5.29), emergency room (ER) access before withdrawal (OR: 2.81; 95% CI: 1.13-6.94) and baseline headache frequency >69 days/three months (OR: 2.97; 95% CI: 1.32-6.65). Patients who failed withdrawal did not improve on medications intake, use of prophylactic and non-pharmacological treatments, symptoms of anxiety and depression.ConclusionsPatients who were treated in day-hospital, those who recently attended ER for headache, and those with more than 69 headache/3 months, as well as to those with relevant symptoms of anxiety and depression who did not improve should be closely monitored to reduce likelihood of non-improvement after structured withdrawal.

Project description:Chronic migraine patients are at risk of developing a medication overuse. Brain functional studies in these patients have demonstrated an orbitofrontal hypometabolism, persistent after overuse cessation. Orbitofrontal dysfunction is also present in addiction and thus could predispose migraineurs to medication overuse. The aim of this study was to investigate if orbitofrontal dysfunction can be demonstrated in patients with chronic migraine and medication overuse by performing a systematic neuropsychological evaluation focused on tests that assess frontal lobe function. Second, to establish whether it is related to the outcome of these patients. We prospectively studied 42 chronic migraine patients with medication overuse, 42 episodic migraineurs and 41 controls on a battery of neuropsychological tasks evaluating the orbitofrontal and dorsolateral functioning. Depression, anxiety, and personality traits were also assessed. Chronic migraineurs with medication overuse showed a significant impairment in orbitofrontal task performance and higher depression scores as compared to episodic migraineurs and controls. Dorsolateral dysfunction was present in both groups of migraneurs, who also had higher rates of anxiety as compared to controls. After 1 year of follow-up, migraine patient's outcome was classified according to their medication overuse status. A negative outcome that included persistent or new-onset medication overuse was present in 34% of migraineurs and was associated with baseline poor orbitofrontal task performance, and with mild dorsolateral dysfunction, higher rates of depression, anxiety and neuroticism-anxiety traits. Formal education and years with migraine did not influence outcome. Orbitofrontal dysfunction is present in patients with chronic migraine and medication overuse, and associates with a poor outcome at 1 year of follow-up. Neuropsychological evaluation in migraine may help to detect patients prone to overuse so that appropriate therapeutic attitudes can be taken.

Project description:ObjectiveTo determine the effect of erenumab, a human anti-calcitonin gene-related peptide receptor monoclonal antibody, in patients with chronic migraine and medication overuse.MethodsIn this double-blind, placebo-controlled study, 667 adults with chronic migraine were randomized (3:2:2) to placebo or erenumab (70 or 140 mg), stratified by region and medication overuse status. Data from patients with baseline medication overuse at baseline were used to assess changes in monthly migraine days, acute migraine-specific medication treatment days, and proportion of patients achieving ≥50% reduction from baseline in monthly migraine days.ResultsOf 667 patients randomized, 41% (n = 274) met medication overuse criteria. In the medication overuse subgroup, erenumab 70 or 140 mg groups had greater reductions than the placebo group at month 3 in monthly migraine days (mean [95% confidence interval] -6.6 [-8.0 to -5.3] and -6.6 [-8.0 to -5.3] vs -3.5 [-4.6 to -2.4]) and acute migraine-specific medication treatment days (-5.4 [-6.5 to -4.4] and -4.9 [-6.0 to -3.8] vs -2.1 [-3.0 to -1.2]). In the placebo and 70 and 140 mg groups, ≥50% reductions in monthly migraine days were achieved by 18%, 36% (odds ratio [95% confidence interval] 2.67 [1.36-5.22]) and 35% (odds ratio 2.51 [1.28-4.94]). These clinical responses paralleled improvements in patient-reported outcomes with a consistent benefit of erenumab across multiple measures of impact, disability, and health-related quality of life. The observed treatment effects were similar in the non-medication overuse subgroup.ConclusionsErenumab reduced migraine frequency and acute migraine-specific medication treatment days in patients with chronic migraine and medication overuse, improving disability and quality of life.Clinicaltrialsgov identifierNCT02066415.Classification of evidenceThis study provides Class II evidence that erenumab reduces monthly migraine days at 3 months in patients with chronic migraine and medication overuse.

Project description:BackgroundChronic migraine with medication overuse headache (CM-MOH) is the most common type of chronic migraine, and it increases risk of stroke and white matter lesions. These pathologic changes could induce cognitive decline. However, the alteration of cognitive function in CM-MOH patients is not established. Therefore, we took this study to reveal the cognitive performances in CM-MOH.MethodsThis cross-sectional study was conducted between December 2015 and January 2017. Patients were divided into CM-MOH, CMwoMOH (chronic migraine without medication overuse), and MO (migraine without aura) groups. Cognitive function was assessed in all cases during interictal periods using Addenbrooke's Cognitive Examination Test (ACE-R), Trail Making Test A/B (TMT A/B), and Digit Symbol Test (DST). Detailed headache characteristics and evaluation of anxiety, depression, and living and sleep quality were collected.Results116 patients were included in this study. There were 21 CM-MOHs, 20 CMwoMOHs, 35 MOs, and 40 controls. Age and education were the independent risk factors of cognitive decline (P < 0.05). After adjusting, the risk of cognitive decline was higher in CM compared with control in ACE-R score and language fluency (P < 0.05). In addition, CM-MOH sufferers were in higher risk of memory and executive dysfunction (P < 0.05). The cognitive function had no difference between CM-MOH and CMwoMOH (P > 0.05). Meanwhile, CM-MOH got significantly higher scores than MO in anxiety and depression, with poorer performances in sleep and life quality (P < 0.05).ConclusionThe risk of cognitive decline increased in chronic migraine patients. Nonsteroid anti-inflammatory drugs overuse had no influence on cognitive performances among chronic migraine sufferers.

Project description:IntroductionUse of triptans for acute treatment of migraine is associated with insufficient efficacy and/or tolerability in approximately 30-40% of people. We conducted a systematic literature review (SLR) to synthesize definitions, terminology, subsequent treatment outcomes, and characteristics associated with this subpopulation.MethodsA comprehensive SLR was conducted to identify studies, published from Jan 1995 to May 2019, which focused on insufficient efficacy and/or tolerability to triptans.ResultsThirty-five publications were identified, of which 22 described randomized controlled trials and open-label studies, and 13 described observational studies. Across studies, multiple objectives and a high amount of variability in methodologies and outcomes were noted. The most commonly applied measures of efficacy were headache pain freedom and pain relief at 2 h. Ten studies assessed efficacy of switching or optimizing treatment in patients with historical insufficient efficacy or tolerability to previous triptan treatment and demonstrated varying levels of success. Factors associated with increased risk of triptan insufficient efficacy included severe baseline headache severity, photophobia, phonophobia, nausea, and depression.ConclusionsIrrespective of the methodology or definition used to identify people with insufficient efficacy and/or tolerability to triptans, study results support the assertion that a high unmet need remains for effective acute treatment of migraine.

Project description:IntroductionAs 5-HT1B receptor agonists, triptans produce vasoconstriction and have cardiovascular contraindications and precautions. Lasmiditan, a selective 5-HT1F receptor agonist, has a low affinity for 5-HT1B receptors, does not cause vasoconstriction, and is free of cardiovascular contraindications and precautions. The objective of this post hoc analysis was to evaluate the efficacy and safety of lasmiditan in patients with and without at least one triptan contraindication.MethodsPatient subgroups, with and without triptan contraindications, were analyzed from pooled patient data from four randomized, double-blind, placebo-controlled clinical trials (SAMURAI, SPARTAN, CENTURION, and MONONOFU). Patients experiencing a single migraine attack of moderate or severe intensity were treated with lasmiditan 50 mg (SPARTAN and MONONOFU only), 100 mg, 200 mg, or placebo, and efficacy data were recorded in an electronic diary.ResultsOf 5704 patients, 207 (3.6%) patients had at least one contraindication to triptans. Overall subgroup analysis revealed that the effects of lasmiditan on pain freedom, pain relief, freedom from most bothersome symptom, disability freedom, and Patient Global Impression of Change at 2 h post-dose did not differ in patient groups with and without triptan contraindications. These outcomes generally showed a similar benefit pattern for lasmiditan in both subgroups, with all results being statistically significant in patients without contraindications, and pain relief being statistically significant in patients with contraindications. The safety and tolerability profiles of patients with triptan versus without triptan contraindications were similar, including dizziness in 18.3 to 22.8% and somnolence in 7.9 to 9.9% of patients at the highest dose of lasmiditan.ConclusionsIn pooled analyses from four trials, patients with and without triptan contraindications did not differ in their patterns of lasmiditan efficacy. Lasmiditan may be a treatment option in patients with contraindications to triptans.Trial registration numbersSAMURAI, NCT:02439320; SPARTAN, NCT:02605174; CENTURION, NCT:03670810; and MONONOFU, NCT:03962738.

Project description:IntroductionMigraine attacks notably impact people's daily lives, health-related quality of life (HRQoL), and ability to work. Triptans are widely used as acute medication for a migraine attack but are ineffective, poorly tolerated, or contraindicated in some patients. HRQoL and work productivity are therefore likely to pose particular problems for patients whose migraine attacks do not respond sufficiently to triptan acute treatment. This real-world study aimed to determine whether migraine-related HRQoL, disability, and work productivity differed between triptan insufficient responders (TIRs) and sufficient responders (TSRs) receiving this acute treatment for migraine in Japan.MethodsThis was a retrospective analysis of 2017 Adelphi Migraine Disease Specific Programme cross-sectional survey data collected from physicians and their consulting patients with migraine in Japan. Patients had to be receiving a triptan as their sole acute prescribed medication for migraine. TIRs were defined as patients who achieved headache pain freedom within 2 h of taking triptan acute treatment in no more than three of five migraine attacks. Differences in outcomes between TIRs and TSRs were examined in adjusted analyses using a multivariable general linear model.ResultsOf 200 patients receiving a triptan as their sole prescribed acute treatment for migraine, 88 (44.0%) were classed as TIRs. Migraine-Specific Quality of Life Questionnaire scores were significantly lower-indicating poorer HRQoL-among TIRs than TSRs, as were mean EuroQol 5-dimension utility and visual analog scale scores (p < 0.05 for comparisons). TIRs also reported significantly (p ≤ 0.003) greater impairment than TSRs across all Work Productivity and Activity Impairment domains, with the exception of work time missed. Migraine disability was higher among TIRs than TSRs.ConclusionMigraine attacks had a negative impact on the HRQoL, disability, and work productivity of people with migraine in Japan reporting insufficient efficacy with acute triptan treatment, highlighting the need for more effective acute treatment options.

Project description:BACKGROUND:Lasmiditan demonstrated superiority to placebo in the acute treatment of migraine in adults with moderate/severe migraine disability in two similarly designed Phase 3 trials, SAMURAI and SPARTAN. Post-hoc integrated analyses evaluated the efficacy of lasmiditan in patients who reported a good or insufficient response to triptans and in those who were triptan naïve. METHODS:Subgroups of patients reporting an overall response of "good" or "poor/none" to the most recent use of a triptan at baseline (defined as good or insufficient responders, respectively) and a triptan-naïve subpopulation were derived from combined study participants randomized to receive lasmiditan 50?mg (SPARTAN only), 100?mg or 200?mg, or placebo, as the first dose. Outcomes including headache pain-freedom, most bothersome symptom-freedom, and headache pain relief 2 hours post-first dose of lasmiditan were compared with placebo. Treatment-by-subgroup analyses additionally investigated whether therapeutic benefit varied according to prior triptan response (good or insufficient). RESULTS:Regardless of triptan response, lasmiditan showed higher efficacy than placebo (most comparisons were statistically significant). Treatment-by-subgroup analyses found that the benefit over placebo of lasmiditan did not vary significantly between patients with a good response and those with an insufficient response to triptans. Lasmiditan also showed higher efficacy than placebo in triptan-naïve patients. CONCLUSIONS:Lasmiditan demonstrated comparable efficacy in patients who reported a good or insufficient response to prior triptan use. Lasmiditan also showed efficacy in those who were triptan naïve. Lasmiditan may be a useful therapeutic option for patients with migraine. TRIAL REGISTRATION:SAMURAI (NCT02439320); SPARTAN (NCT02605174).

Project description:ObjectiveTo characterize nationwide utilization patterns of migraine pharmacotherapy before, during, and after pregnancy in women with triptan use.MethodsPopulation-based data were obtained by linking the Medical Birth Registry of Norway and the Norwegian Prescription Database from 2006 to 2017. We included 22,940 pregnancies among 19,669 women with at least one filled triptan prescription, a proxy for migraine, in the year before pregnancy or during pregnancy. The population was classified into four groups: i) continuers; ii) discontinuers; iii) initiators, and vi) post-partum re-initiators. Participant characteristics and prescription fills for other drugs such as analgesics, antinauseants, and preventive drugs among the groups were examined, along with an array of triptan utilization parameters.ResultsIn total, 20.0% of the women were classified as triptan continuers, 54.1% as discontinuers, 8.0% as initiators, and 17.6% as re-initiators. Extended use of triptans (≥15 daily drug doses/month) occurred among 6.9% of the continuers in the first trimester. The top 10% of triptan continuers and initiators accounted for 41% (95% CI: 39.2% - 42.5%) and 33% (95% CI: 30.3% - 35.8%) of the triptan volume, respectively. Triptan continuers and initiators had similar patterns of acute co-medication during pregnancy, but use of preventive drugs was more common among the continuers before, during, and after pregnancy.ConclusionAmong women using triptans before and during pregnancy, one in four continued triptan treatment during pregnancy, and extended triptan use was relatively low. Triptan discontinuation during and in the year after pregnancy was common. Use of other acute migraine treatments was higher among both continuers and initiators of triptans. Women using preventive migraine treatment were most commonly triptan continuers and re-initiators after pregnancy. Prescribing to and counseling of women with migraine should be tailored to the condition severity and their information needs to promote optimal migraine management in pregnancy.
