RESUMO

BACKGROUND: Several studies have focused on the use of triptan and the risk of acute vascular events but the existence of such association is still debated and has never been quantified in patients over 65 years. To assess whether triptan use among older is associated with an increased risk of hospitalization for acute vascular events. METHODS: A propensity score-matched cohort study was designed using the French national health insurance database linked to hospital stays. Patients aged ≥ 65 years, newly treated by triptans between 2011 and 2014, were included… The primary event was hospitalization for an acute ischemic vascular event within de 90 days following triptan initiation. Association with triptan exposure was investigated through cox regression model, considering exposure at inclusion, and with exposure as a time-varying variable A case-crossover (CCO) and a self-controlled case series (SCCS) analyses were also conducted to address potential residual confounding. RESULTS: The cohort included 24, 774 triptan users and 99 096 propensity matched controls (mean (SD) age: 71 years (5.9), 74% of women). Within 90 days after cohort entry, 163 events were observed in the triptan group, and 523 in the control group (0.66% vs. 0.53%, adjusted hazard ratio (aHR) exposed/not exposed 1.25 95%CI [1.05-1.49]; aHR time-varying 8.74 [5.21-14.66]). The association was significant (CCO) for all events (adjusted odds ratio (aOR1.63 [1.22-2.19]) with a more consistent association with cerebral events (aOR 2.14 [1.26-3.63]). The relative incidence (RI) for all events was 2.13 [1.76-2.58] in the SCCS, for cardiac (RI: 1.67 [1.23-2.27]) and for cerebral events (RI: 3.20, [2.30-4.45]). CONCLUSION: The incidence of acute vascular events was low among triptan users. We found that triptan use among older may be associated with a low increased risk for acute vascular events, which may be more marked for cerebral events such as stroke, than for cardiac events.

RESUMO

BACKGROUND: Most migraine patients need an effective acute medication. Real-world data can provide important information on the performance of acute migraine medication in clinical practice. METHODS: We used data from the German Migraine and Headache Society Headache Registry, where patients rate efficacy and tolerability of and satisfaction with each of their acute headache medications. RESULTS: A total of 1756 adult migraine patients (females: 85%, age: 39.5 ± 12.8 years, headache days per month: 13.5 ± 8.1) were included. Of these, 93% used acute medication, most frequently triptans (59.3%) and/or non-opioid analgesics (56.4%), and 58.5% rated efficacy as good or very good. This was more frequent for triptans (75.4%) than for non-opioid analgesics (43.6%, p < 0.001). Among non-opioid analgesics, naproxen was rated most effective (61.9% very good or good, p < 0.001 compared to ibuprofen, acetylsalicylic acid and paracetamol). Patient-rated efficacy significantly declined with higher headache frequencies (p < 0.001), and this effect remained significant after omitting patients overusing acute medication. CONCLUSION: In the present population recruited at specialized headache centers, patients rated triptans as more effective than non-opioid analgesics, naproxen as more effective than ibuprofen, and acute medication efficacy decreased with increasing headache frequency.Trial registration: The German Migraine and Headache Society Headache Registry is registered with the German Clinical Trials Register (DRKS 00021081).

RESUMO

OBJECTIVE: To describe the pattern of triptan use by gender in Tuscany, Italy, focusing on special user populations in which evidence on triptan safety is still not conclusive. BACKGROUND: Growing evidence supports the role of gender differences in migraine pathophysiology and treatment. However, gender impact on triptan real-word utilization has been poorly investigated. METHODS: A retrospective, descriptive, cohort study was performed using the population-based Administrative Healthcare Database of Tuscany region (Italy). Subjects registered in the database on the January 1 of each year between 2008 and 2018 were identified. New users (NU) of triptans (ATC:N02CC*) were patients with one or more triptan dispensation during the year of interest and none in the past. Age, cardiovascular comorbidities representing an absolute or a possible contraindication to triptan utilization, concomitant serotonergic medications, and pattern of triptan use during 1-year follow-up were described by gender. RESULTS: A total of 86,109 patients who received one or more triptan dispensing were identified. Of 64,672 NU (men = 17,039; women = 47,633), 10.2% (6823/64,672) were aged >65 years, who were mostly women (n = 4613). Among NU, men and women with absolute cardiovascular contraindications were 4.3% (740/17,039) and 2.1% (1022/47,633), respectively, while those concomitantly taking serotonergic medications were 17.2% (267/1549) and 21.9% (949/4330), respectively (949/4330). Regular users (two or more dispensing with ≥3 months between first and last observed dispensing) accounted for 26.4% of women (12,597/47,633) and 19.11% of men (3250/17,039); frequent users (≥15 dosage units/month during ≥3 consecutive months) were overall 0.1% (94/64,672) and 62.0% (58/94) of them concomitantly received serotonergic medications. CONCLUSION: Considering gender differences in triptan use highlighted here, large scale observational studies are warranted to better define what populations are safe to use triptans and whether it is appropriate to tighten or relax certain recommendations on triptan use. In the meantime, any suspected adverse drug reaction observed in the special user populations highlighted in this study should be promptly reported.

RESUMO

OBJECTIVE: To gather information about prescription of triptans and to evaluate whether vascular comorbidity differs in users and nonusers of triptans over the age of 50 years. BACKGROUND: Beyond the age of 50 years, migraine is still common-yet the incidence of vascular disorders increases. Triptans, medications for treating migraine attacks, are vasoconstrictive drugs and contraindicated in persons with vascular disorders. METHODS: Based on a nationwide insurance database from 2011, we compared the prescription of vascular drugs (identified by Anatomical Therapeutic Chemical codes), vascular diagnoses and hospitalizations, between triptan users greater than 50 years and a matched control group. RESULTS: Of the 3,116,000 persons over 50 years, 13,833 (0.44%) had at least one triptan prescription; 11,202 (81%) were women. Thirty percent of the triptan users (13,833/47,336 persons) were over 50 years. Of those over 50 years, 6832 (49.4%) had at least one vascular drug and 870 (6.3%) had at least one inpatient vascular diagnosis; 15.7% (2166 of 13,833 users) overused triptans. We compared triptan-users to 41,400 nonusers, using a 1:3 match. In triptan-users, prescriptions of cardiac therapies and beta blockers were significantly more common (odds ratio [OR] = 1.35, 95% confidence interval [CI] = 1.24-1.47 and OR = 1.19, 95% CI = 1.14-1.25, respectively); whereas prescriptions of calcium channel blockers and renin/angiotensin inhibitors were significantly less common (OR = 0.82, 95% CI = 0.76-0.88 and OR = 0.75, 95% CI = 0.72-0.79, respectively). The prescriptions of antihypertensive, diuretic, and antilipidemic drugs as well as platelet inhibitors and direct thrombin inhibitors did not differ in users and nonusers. Triptan users had significantly more hospital stays (OR = 1.39, 95% CI = 1.33-1.45); however, the number of days spent in the hospital and more importantly the frequency of inpatient vascular diagnoses did not differ statistically significantly between the two groups. CONCLUSION: In persons over 50 years of age, a prescription of triptans is common. Vascular comorbidity is comparable in users and nonusers of triptans showing that triptans are prescribed despite vascular comorbidity and suggesting that triptan use does not increase vascular risk in patients with migraine over the age of 50 years. Nevertheless, regular evaluation for contraindications against triptans and for vascular risk factors is recommended in this age group.

RESUMO

OBJECTIVE: To characterize the clinical features of patients with medication-overuse headache (MOH) according to the class of acute medications being overused. BACKGROUND: MOH is a common global health problem, severely disabling the majority of the patients affected. Although various medications can cause MOH, whether clinical features differ according to the overused medication type remains unclear. METHODS: We analyzed data from a multicenter cross-sectional study in neurology clinics in Korea from April 2020 to June 2021. RESULTS: Among 229 eligible patients, MOH was documented in patients who overused multiple drug classes (69/229, 30.1%; most frequent occurrence), triptans (50/229, 21.8%), non-opioid analgesics (48/229, 21.0%), and combination-analgesics (40/229, 17.4%). Patients who overused multiple drug classes reported more frequent use of acute medications (median [25th-75th percentiles]: 25.0 [15.0-30.0] vs. 17.5 [10.0-25.5] days/month, p = 0.029) and fewer crystal-clear days (0.0 [0.0-9.5] vs. 9.0 [0.0-10.0] days/month, p = 0.048) than those who overused triptans. Patients who overused multiple drug classes also reported shorter intervals from chronic daily headache to the onset of MOH than patients who overused combination-analgesics (0.6 [0.2-1.9] vs. 2.4 [0.7-5.4] years, p = 0.001) or non-opioid analgesics (1.5 [0.6-4.3] years, p = 0.004). Patients who overused multiple drug classes reported more emergency room visits (1.0 [0.0-1.0] visits/year) than those who overused combination-analgesics (0.0 [0.0-1.0], p = 0.024) or non-opioid analgesics (0.0 [0.0-1.0], p = 0.030). Patients who overused triptans reported fewer headache days (21.0 [20.0-30.0] vs. 30.0 [20.5-30.0] days/month, p = 0.008) and fewer severe headache days (7.0 [4.0-10.0] vs. 10.0 [5.0-15.0] days/month, p = 0.017) than those who overused non-opioid analgesics. CONCLUSIONS: Some clinical characteristics of MOH significantly differed according to the class of overused medications. The findings from this study may contribute to the understanding of the clinical characteristics and pathophysiology of MOH.

RESUMO

OBJECTIVE: Calcitonin gene-related peptide (CGRP) receptor antagonists have been suggested as novel treatments for acute migraine. This study aimed to use meta-analysis to compare the safety and tolerability of five existing oral CGRP receptor antagonists (BI44370TA, MK-3207, rimegepant, telcagepant, and ubrogepant) with that of a placebo or triptans against acute migraine. METHODS: Five prominent databases were searched to identify randomized controlled trials on this topic. The primary safety outcomes of interest were any adverse events (AEs) and treatment-related adverse events (TRAEs), and secondary outcomes were individual events, namely diarrhea, dizziness, dry mouth, fatigue, nausea, paresthesia, somnolence, upper abdominal pain, and vomiting. RESULTS: Fifteen studies met the eligibility criteria and were examined in detail. Although, compared to placebo, oral CGRP receptor antagonists significantly increased the incidence of any AEs (risk ratio [RR] = 1.15; 95% confidence interval [CI] = 1.07-1.23), there was no difference in the incidence of TRAEs (RR = 1.18; 95% CI = 1.00-1.38). Moreover, CGRP receptor antagonists were safer than triptans with respect to primary safety outcomes, such as any AEs (RR = 0.78; 95% CI = 0.63-0.98) and TRAEs (RR = 0.68; 95% CI = 0.58-0.79). CONCLUSION: Despite oral CGRP receptor antagonists posing a significantly higher risk of AEs when compared to placebo, CGRP receptor antagonists have a favorable safety profile compared to triptans. Our findings inform strategies to enhance safety and tolerability in the treatment of acute migraine.

RESUMO

PURPOSE OF REVIEW: The aim of this review is to aid in choosing safe options when assessing potential risks of acute migraine treatments based on known mechanisms of action and anticipated safety concerns. RECENT FINDINGS: Part 1 highlights safety issues associated with commonly used medications to treat acute migraine attacks. Strategies to mitigate cardiovascular and gastrointestinal risks of nonsteroidal anti-inflammatory drugs, evaluation of cardiovascular risks of triptan and ergot alkaloids, and precautions with use of antiemetics and the novel drugs gepants and ditans are discussed to help practitioners in clinical decision-making. When available, we included recommendations from professional societies and data from pharmacovigilance systems. While guidelines on efficacy are available, one must also consider the possible risks and adverse effects of a drug when creating treatment plans.

RESUMO

PURPOSE OF REVIEW: The aim of this study was to review current evidence concerning potential risks and interactions associated with concomitant use of drugs indicated for the abortive treatment of migraine, namely triptans and ditans, and more recently developed drugs used for the preventive treatment. The latter drug class encompasses monoclonal antibodies (mAbs), which target either calcitonin gene-related peptide (CGRP) or its receptor. RECENT FINDINGS: To date, no pharmacokinetic interactions between these drug classes have been reported. However, patients who suffer from triptan- (or ditan-) induced medication overuse headache or those who are nonresponders to triptans might respond less effectively to mAbs. Caution is warranted when coadministrating these drugs in migraine patients with comorbid cardiovascular disease or with an increased cardiovascular risk profile. SUMMARY: In this review, the main mechanisms of action of triptans, ditans and mAbs targeting CGRP or its receptor are summarized as well as the current evidence on their individual risks. Studies on risks and interactions in case of concomitant use of triptans, ditans and mAbs in migraine patients are relatively scarce. Therefore, these aspects have been considered from a theoretical and hypothetical point of view by taking both their overlapping target, CGRP, and contraindications into account.

RESUMO

BACKGROUND: A synthesis of real-world discontinuation and switching patterns among triptan users and rates of acute medication use among patients with medication overuse headache (MOH) is needed to better understand the burden among patients with migraine. The study objectives were to: (1) synthesize rates of switching and discontinuation from triptans; (2) characterize acute medication use among patients with MOH; and (3) describe the associated burden. METHODS: A systematic literature review was conducted, under the Preferred Reporting Items for Systematic Review guidelines, using MEDLINE/EMBASE from database inception to July 2019. The search strategy targeted studies of adults with migraine, and included terms related to migraine and its treatment. Continuous variables were summarized using means, standard deviations, and ranges. Dichotomous and categorical variables were summarized using the number and proportion of individuals. RESULTS: Twenty studies were included; seven describing patterns of switching and discontinuation among triptan users, and 13 characterizing triptan overuse among patients with MOH. High rates of switching to non-specific acute medications and low two-year retention rates were reported; among US samples switching to opioids at the first refill (18.2%) or after 1-year (15.5%) was frequent. Compared to persistent use of triptans, switchers experienced greater headache related impact and either no improvement or increased headache-related disability. Rates of medication overuse by agent among patients with MOH varied greatly across the included studies, and only one study described factors associated with the risk of MOH (e.g. duration of medication overuse). Medication agent, increased headache frequency (p = .008), and increased disability (p = .045) were associated with unsuccessful withdrawal; patients overusing triptans were more successful at withdrawal than those overusing opioids or combination analgesics (P < .0001). CONCLUSIONS: The evidence summarized here highlights that rates of WCS are low and many patients turn to other acute medication at their first refill. Patients may experience no improvement in disability when switching from one triptan agent to another, or experience increasing disability and/or increasing migraine frequency when turning to traditional acute treatment for migraine. Variability in health care settings, patient severity, and study design contributed to heterogeneity across the synthesis.

RESUMO

OBJECTIVE: To determine the long-term safety and tolerability profile of M207 in the acute treatment of migraine. BACKGROUND: M207 is an investigational microneedle-based system for intracutaneous delivery of zolmitriptan for the treatment of migraine attacks. Following on the positive results of a Phase 2/3 placebo-controlled efficacy study (ZOTRIP), this study was designed to evaluate the safety of this novel product during repeated use for the treatment of migraine attacks. METHODS: In this 6-12 month open-label, multicenter observational study, participants used an eDiary to record headache symptoms and adverse events at specified intervals up to 48 h following treatment of a qualifying attack with M207 3.8 mg (intracutaneous zolmitriptan). Participants underwent clinical evaluations at specified intervals up to 12 months. RESULTS: Among 335 participants who treated ≥1 migraine attack, 257 completed 6 months and 127 completed 1 year of treatment. The most common reason for withdrawal from the study was a low frequency of reported attacks post randomization. Overall, 5963 migraine attacks were treated. Most participants (96%) experienced at least 1 adverse event, the vast majority of which concerned the application site, and > 95% of which were mild. Fifteen participants (4%) withdrew due to adverse events; 4 withdrew due to 7 application site reactions, 6 of which were mild. Participants achieved pain freedom in 2477/5617 (44%) of attacks, most bothersome symptom freedom in 3315/5330 (62%) of attacks, and pain relief 2 h post-dose in 4552/5617 (81%) of attacks. Sustained pain freedom 2-24 h was seen in 1761/4698 (38%) of attacks, and 2-48 h in 1534/4429 (35%) of attacks. CONCLUSIONS: The majority of participants experienced cutaneous adverse reactions such as application site erythema, swelling, and bleeding, and most reactions were scored as mild. These results are consistent with what was observed in the single migraine attack treatment ZOTRIP trial indicating that M207 is well tolerated in the setting of longer-term repeated use. Efficacy findings were also similar to those in the ZOTRIP trial. TRIAL REGISTRATION: Clinicaltrials.gov on September 13, 2017 ( NCT03282227 ).

RESUMO

OBJECTIVE: The goal of this study is to determine the strength of association between treatment with triptans and acute myocardial infarction, heart failure, and death. BACKGROUND: Case reports in the literature have raised concerns over an association between treatment of migraine headaches with triptans and cardiovascular events. This study aims to systematically evaluate this association in a contemporary population-based cohort. We hypothesized that triptan exposure is not associated with increased cardiovascular events. METHODS: A retrospective cohort study was conducted within an integrated healthcare delivery system in Southern California. From January 2009 to December 2018, 189,684 patients age ≥18 years had a diagnosis of migraine. In this group, 130,656 were exposed to triptans. Patients treated with triptans were matched 1:1 to those not exposed to triptans by using a propensity score. The primary outcome was acute myocardial infarction; secondary outcomes were heart failure, all-cause death, and combined acute myocardial infarction, heart failure, and death. RESULTS: The incidence rate of acute myocardial infarction was 0.67 per 1000 person-year in triptan-exposed vs 1.44 per 1000 person-year in not exposed patients. In propensity-matched analyses, the adjusted hazard ratio for triptan exposure was 0.95 (95% confidence interval [CI] 0.84-1.08) for acute myocardial infarction; 1.00 (95% CI 0.93-1.08) for all-cause death; 0.93 (95% CI 0.81-1.08) for heart failure; and 0.99 (95% CI 0.93-1.06) for a composite of acute myocardial infarction, heart failure, or death. Sensitivity analyses focusing on stratified subgroups based on age, gender, ethnicity, and several cardiac risk factors also revealed no significant association between triptan exposure and cardiovascular events. CONCLUSIONS: No association was found between exposure to triptans and an increased risk of cardiovascular events. These data provide reassurance regarding the cardiovascular safety of utilizing triptans for the medical management of migraine headaches.

RESUMO

PREMISES: Patients with migraine have a co-morbidity with vascular diseases such as hypertension, coronary heart disease, and stroke. PROBLEM: This overview gives recommendations for the therapy of acute migraine attacks and for migraine  prevention in patients with vascular diseases. In particular, the use of triptans in patients with vascular diseases is discussed. POTENTIAL SOLUTIONS: Currently, there is a contraindication for the use of the triptans in patients with vascular disease, although there is no evidence that triptans increase the risk of heart attacks or stroke.

RESUMO

OBJECTIVE: To evaluate the potential for pharmacokinetic interaction and the safety and tolerability when ubrogepant and sumatriptan are coadministered in a Phase 1 study in healthy participants, and to inform the safety and tolerability of ubrogepant alone and in combination with triptans in Phase 3 trials in participants with migraine. BACKGROUND: Calcitonin gene-related peptide is a potent vasodilatory neurotransmitter believed to play a key role in the pathophysiology of migraine. Ubrogepant (UBRELVY™) is a potent and selective antagonist of the human calcitonin gene-related peptide receptor approved for the acute treatment of migraine. Sumatriptan is a serotonin receptor agonist and the most commonly used triptan for the acute treatment of migraine. Ubrogepant could be prescribed with triptans. DESIGN: The Phase 1 study was a single-center, open-label, randomized, 3-way crossover, single-dose, pharmacokinetic interaction study, where participants received each of 3 oral treatments with a 7-day washout period between treatments: single dose of ubrogepant 100 mg, single dose of sumatriptan 100 mg, and ubrogepant 100 mg plus sumatriptan 100 mg. Pharmacokinetic parameters were calculated using a model-independent approach. The ACHIEVE I and II trials were 2 multicenter, single-attack, randomized, Phase 3 trials in adults with a history of migraine with or without aura. Participants had the option to take a second dose of study medication or rescue medication to treat a nonresponding migraine or a migraine recurrence from 2 to 48 hours after the initial dose of study medication. Rescue medication options included acetaminophen, nonsteroidal anti-inflammatory drugs, opioids, anti-emetics, or triptans. Treatment-emergent adverse events were evaluated up to 30 days after the last dose in the Phase 1 and Phase 3 studies. RESULTS: Ubrogepant median time to maximum plasma concentration was delayed (3 hours [range: 1-5 hours] vs 1.5 hours [range: 1-4 hours]), mean maximum plasma concentration was reduced by 24% (coefficient of variation: 37.4%) when ubrogepant was coadministered with sumatriptan (n = 29) compared with ubrogepant administered alone (N = 30). No significant effect was observed on the area under the plasma concentration-time curve of ubrogepant. Sumatriptan area under the curve and maximum plasma concentration showed no significant change when sumatriptan was coadministered with ubrogepant (n = 29), but the sumatriptan time to maximum plasma concentration was delayed (1 hour [range: 0.5-5 hours] vs 3 hours [range: 0.5-6 hours]. No treatment-emergent adverse events were reported with the coadministration of ubrogepant 100 mg and sumatriptan 100 mg in the Phase 1 study. The pooled safety data from ACHIEVE trials (N = 1938) showed similar rates of treatment-related treatment-emergent adverse events between participants who took ubrogepant alone and participants who took ubrogepant and a triptan as a rescue medication (14.9% [53/355] vs 12.8% [5/39] in the ubrogepant 100 mg treatment group, respectively). CONCLUSIONS: Although there were slight alterations in ubrogepant pharmacokinetic parameters when coadministered with sumatriptan, such changes are expected to have minimal clinical relevance, especially because no changes were seen in sumatriptan area under the curve and maximum plasma concentration when coadministered with ubrogepant. Coadministration of ubrogepant with sumatriptan was well tolerated in healthy participants in the Phase 1 study, and coadministration of ubrogepant with triptans was well tolerated in participants with migraine in the Phase 3 trials. No new safety concerns for ubrogepant were identified across all trials.

RESUMO

Our understanding of tryptamines is poor due to the lack of data globally. Tryptamines currently are not part of typical toxicology testing regimens and their contribution to drug overdoses may be underestimated. Although their prevalence was low, it is increasing. There are few published data on the many new compounds, their mechanisms of action, onset and duration of action, toxicity, signs and symptoms of intoxication and analytical methods to identify tryptamines and their metabolites. We review the published literature and worldwide databases to describe the newest tryptamines, their toxicology, chemical structures and reported overdose cases. Tryptamines are 5-HT2A receptor agonists that produce altered perceptions of reality. Currently, the most prevalent tryptamines are 5-methoxy-N,N-diisopropyltryptamine (5-MeO-DiPT), 5-methoxy-N,N- diallyltryptamine (5-MeO-DALT) and dimethyltryptamine (DMT). From 2015 to 2020, 22 new analytical methods were developed to identify/quantify tryptamines and metabolites in biological samples, primarily by liquid chromatography tandem mass spectrometry. The morbidity accompanying tryptamine intake is considerable and it is critical for clinicians and laboratorians to be informed of the latest data on this public health threat.

RESUMO

PREMISE: The science of migraine pathophysiology has advanced significantly since the 1930's. Imaging techniques, neurochemical analysis, clinical trials, and the clinical experience of providers treating migraine patients have not only sharpened our understanding of the disease, but have also led to the development of novel neural-based targets. Targeted therapies such as calcitonin gene-related peptide (CGRP) antibodies and "Second Generation" CGRP receptor antagonists (Gepants) have not only demonstrated efficacy, but have not resulted in any significant cardiovascular nor other serious adverse events. "First Generation" Gepants were associated with liver toxicity. PROBLEM: Triptans and dihydroergotamine (DHE) are contraindicated in patients with hemiplegic and basilar migraine based on theories of migraine pathophysiology from the 1930s. While our understanding of migraine has evolved substantially, perceived concerns of safety from almost a century ago continue to preclude their use in certain patient populations. POTENTIAL SOLUTION: While migraine aura was once thought to be primarily due to vasoconstriction, current evidence debunks this concept. For instance, hemiplegic migraine is the consequence of genetic mutations resulting in channelopathies without evidence of cerebral ischemia or infarction. Evidence of basilar artery constriction as postulated in basilar migraine is also lacking. This recognition has led the International Headache Society to rename basilar-type migraine to migraine with brainstem aura. The following discussion reviews current literature with respect to migraine as a neuronal disorder, as well as the published data on the safety of triptans, DHE, Ditans (a novel class of 5-HT1f receptor agonists), CGRP antibodies, and Gepants.

RESUMO

BACKGROUND: The International Classification of Headache Disorders lists different subtypes of medication overuse headache (MOH), according to the medication overused. The aim of this study is to evaluate whether the different subtypes correspond to clinically distinguishable phenotypes in a large population. METHOD: This descriptive cross-sectional observational study included 660 patients with MOH referred to headache centers in Europe and Latin America as a part of the COMOESTAS project. Information about clinical features was collected with structured patient interviews and with self-administered questionnaires for measuring disability, anxiety, and depression. RESULTS: Female/male ratio, body mass index, marital status, and level of education were similar among in subjects enrolled in the 5 centers. The mean age was higher among subjects overusing triptans (T-MOH) with respect to subjects overusing simple analgesic (A-MOH). Duration of headache before chronification was longer in T-MOH (19.2 ± 11.9 years) and in subjects overusing ergotamines (E-MOH, 17.8 ± 11.7 years) with respect to the A-MOH group (13.1 ± 10.9; P < .001 and P = .017, respectively) and in T-MOH with respect multiple drug classes (M-MOH, 14.9 ± 11.7; P = .030). Migraine Disability Assessment (MIDAS) score was significantly lower in E-MOH group (33.6 ± 41.6), while T-MOH group (56.8 ± 40.6) had a significant lower MIDAS score with respect to M-MOH (67.2 ± 62.5; P = .016 and P = .037, respectively). Prevalence of depression and anxiety was lower in patients overusing T with respect to other groups of patients (χ2  = 10.953, P = .027 and χ2  = 25.725, P < .001, respectively). CONCLUSION: In this study on a large and very well characterized population of MOH, we describe the distinctive clinical characteristics of MOH subtypes. These findings contribute to more clearly define the clinical picture of a poorly delineated headache disorder. They also provide some insights in the possible trajectories leading to this highly disabling chronic headache, that is classified as a secondary form, but whose occurrence is entirely dependent on an underlying primary headache.

RESUMO

Migraine is a common disabling disorder that affects 36 million Americans. The clinical features of migraine are less typical in the people above age 60, making the diagnosis and treatment difficult in this group. In this review, we will discuss migraine-specific drugs and their use in populations about age 60 who suffer from migraine. This discussion will include an overview of traditional treatments for the acute and preventive treatment of migraine, and considerations for their use in patient populations above age 60. In addition, we will discuss newer agents that show a more promising safety profile.

RESUMO

Objective The objective of our study is to assess the impact of triptan exposure on pregnancy outcome. Methods We performed a prospective observational cohort study with 432 pregnant women exposed to triptans and enrolled by the German Embryotox system. Pregnancy outcomes were compared with a migraine and a non-migraine comparison cohort. Primary objectives were major birth defects and spontaneous abortion; secondary endpoints were preterm delivery, birth weight, pregnancy complications and the rate of electively terminated pregnancies. Results Compared to a non-migraine cohort the rates of major birth defects (ORadj 0.84; 95% CI 0.4-1.9), spontaneous abortions (ORadj 1.20; 95% CI 0.9-1.7), preterm delivery (ORadj 1.01; 95% CI 0.7-1.5), and preeclampsia (ORadj 1.33; 95% CI 0.7-2.5) were not increased in triptan-exposed pregnancies. Conclusions Our findings support the evidence that triptans are not major teratogens. When compellingly needed during pregnancy, sumatriptan as the best studied triptan appears an acceptable treatment option. A detailed fetal ultrasound should be offered in cases of first trimester exposure to less well-studied triptans. Trial registration number in German Clinical Trials Register: DRKS00007660.

RESUMO

BACKGROUND: Triptans are commonly used to treat migraine headaches, but data on the long-term safety of these medications during pregnancy are sparse. Triptans have a biologically plausible mechanism for effects on the fetal brain through binding to 5-HT1 -receptors, and previous studies show increased risks of externalising behaviour problems in toddlers exposed to triptans during pregnancy. METHODS: We included 3784 children in the Norwegian Mother and Child Cohort Study, whose mothers returned the 5-year-questionnaire and reported a history of migraine or triptan use; 353 (9.3%) mothers reported use of triptans during pregnancy, 1509 (39.9%) reported migraine during pregnancy but no triptan use, and 1922 (50.8%) had migraine prior to pregnancy only. We used linear and log-binomial models with inverse probability weights to examine the association between prenatal triptan exposure and internalising and externalising behaviour, communication, and temperament in 5-year-old children. RESULTS: Triptan-exposed children scored higher on the sociability trait than unexposed children of mothers with migraine (ß 1.66, 95% confidence interval [0.30, 3.02]). We found no other differences in temperament, or increased risk of behaviour or communication problems. CONCLUSIONS: Contrary to results from previous studies in younger children, we found no increased risk of externalising behaviour problems in 5-year-old children exposed to triptans in fetal life. Triptan-exposed children did have slightly more sociable temperaments, but the clinical meaning of this finding is uncertain.
