Prophylactic Treatment Of Migraine Research Articles

TRATAMENTO FARMACOLÓGICO COMO PROFILAXIA DA CEFALEIA PRIMÁRIA DO TIPO MIGRÂNEA: UMA ANÁLISE DA EFICÁCIA DOS MEDICAMENTOS

INTRODUCTION: Migraine headache is a neurological problem, varying in form and intensity, being a disruptive factor in the lives of those affected. OBJECTIVE: To present the main prophylactic pharmacological treatments for migraine, evaluating their effects and safety in comparison to other treatments. METHODS: The search was carried out through the VHL in the MEDLINE and LILACS databases, using studies from the last 5 years and with full text available in English and Portuguese. Of the 200 articles initially evaluated, 61 were selected to compose the final corpus of the study. RESULTS: 32 treatments were found available for migraine prophylaxis, with emphasis on monoclonal antibodies to the peptide related to the calcitonin gene, which reduce the frequency, duration and intensity of migraine attacks, providing a comparative improvement in relation to conventional therapies. Medications such as beta-blockers, angiotensin II antagonists, antiepileptics and onabotulinumtoxinA have also demonstrated efficacy in obtaining positive responses to migraine treatment. CONCLUSION: Evidence suggests that, due to the multiple therapeutic approaches to migraine, personalized treatment is necessary, considering the individual response to the intervention and the risk of damage in the care plan.

Petasites hybridus in migraine prophylaxis: literature review

IntroductionOver the past 25 years, Petasites hybridus has been used effectively in migraine prophylaxis. It acts on its pathophysiological mechanisms, modulating nociception, reducing the release of CGRP, decreasing inflammatory mediators and blocking calcium channels.ObjectiveTo review clinical studies already published on Petasites hybridus in migraine prophylaxis, with emphasis on the initial study by Grossmann and Schmidramsl in 2000.MethodsThis study was an integrative and retrospective review of articles on the use of Petasites hybridus in the prophylactic treatment of migraine that were published in English in the last 25 years.ResultsFive clinical studies were found, all placebo-controlled, three of which were double-blind, involving 488 patients with migraine aged between 6 and 60 years. These studies showed that Petasites hybridus was superior to placebo, proving its effectiveness in the prophylactic treatment of migraine and with good tolerability, including by children and adolescents.ConclusionsClinical studies proved that Petasites hybridus was well tolerated by children and adults and effective in migraine prophylaxis, reducing the number of days with headache by ≥ 50% in the first three months.

Adverse events associated with Atogepant: a FAERS-based pharmacovigilance analysis

ABSTRACT Background Migraine, a prevalent neurovascular disorder, can significantly disrupt an individual’s daily life. Atogepant (AGN-241689), an orally administered small-molecule drug classified as a calcitonin gene-related peptide receptor antagonist, is utilized for prophylactic migraine treatment. The objective of this study was to investigate adverse events (AEs) associated with atogepant through data mining in the FDA Adverse Event Reporting System (FAERS) to enhance clinical safety. Methods Data for atogepant were obtained from the FAERS database covering Q3 2021 through Q4 2023. Disproportionality analysis was employed to quantify relevant AEs associated with atogepant. Reported Ratio of Ratios (ROR) was utilized for identifying risk signals within the FAERS data. This methodology relies on the System Organ Class (SOC) and Preferred Terminology (PT) of the Medical Dictionary for Regulatory Activities (MedDRA). Results From the FAERS database, a collection of 7,991,243 reports was obtained. Among these reports, a subset of 3015 was identified as ‘primary suspected (PS)’ AEs specifically related to atogepant. AEs induced by atogepant were observed across 27 organ systems. A total of 48 significantly disproportionate Preferred Terminologies (PTs) meeting all four algorithms were identified. Conclusion Our study has identified adverse events (AEs) associated with atogepant, potentially providing crucial support for the clinical monitoring and risk identification of atogepant.

Female sexual dysfunction and distress in premenopausal women with migraine followed in a tertiary headache center: A pilot study

BackgroundFemale sexual dysfunction (FSD) is an underdiagnosed and undertreated problem. Few studies have addressed sexual distress in migraine. We aimed to perform a pilot study to determine if there is an association between migraine and sexual dysfunction/distress in premenopausal women and to identify their respective risk factors. MethodsRetrospective, cross-sectional pilot study, including 71 premenopausal female patients with migraine, from the headache outpatient clinic of a tertiary hospital, and 34 age-matched-controls. Female Sexual Function Index-6 (FSFI-6), Female Sexual Distress Scale-Revised (FSDS-R), Migraine Disability Assessment (MIDAS) Scale, Brief Pain Inventory (BPI), Hospital Anxiety and Depression Scale (HADS) and Sleep Health Scale (RU-SATED) were applied. ResultsOf the 71 patients [40.0 (IQR = 11.00) years], only 12.7 % (n = 9) were not under migraine prophylactic treatment, and most (n = 33, 62.3 %) reported severe disability (MIDAS-IV). FSD and sexual distress were present in 50.7 % (36) patients with migraine [vs 20.6 % (7) controls]. Migraine patients showed lower FSFI-6 scores [19.0 (9.0) vs 24.0 (6.0), p = 0.005], with significantly lower levels of desire (p = 0.011), lubrication (p = 0.002), and satisfaction (p = 0.013), higher sexual distress [11.2 (25.6) vs 3.2 (9.6), p = 0.001], anxiety (p < 0.001), and depression (p < 0.001) levels, and lower sleep health scores (p = 0.005). Old age of onset, being under preventive medication, anxiety/depression, and dysfunctional sleep, were significantly associated with sexual distress. Certain domains of sexual function were associated with sociodemographic and migraine characteristics, anxiety, depression, and sleep health. ConclusionsThis pilot study highlights the possible association between migraine and elevated sexual dysfunction/distress levels among premenopausal women. It underscores the importance of sexual health assessments in these individuals, particularly those with higher levels of anxiety, depression, or poor sleep quality. It is important to exercise caution when interpreting results, as they may not be applicable to a wider context. This research paves the way for a larger study that will include a broader population of women from the community and encompass patients followed in different levels of health care.

Real-world experiences of migraine patients on Erenumab: a Kuwait single center cohort

ABSTRACT Background Migraine is a prevalent headache disorder with a significant impact on the quality of life. This study aims to investigate the effectiveness and safety of erenumab, mAb targeting the CGRP receptor, in treating chronic (CM) and episodic (EM) migraine in clinical practice Kuwait, providing region-specific insights to treatment options. Method This was a prospective observational cohort study of patients diagnosed with EM or CM treated with erenumab. The primary outcome of the study was to assess the proportion of patients achieving ≥ 50% reduction in monthly mean migraine days, and several changes including the mean number of monthly migraine days, the frequency of analgesic use, attack severity, AEs, and QoL. Results The study included 151 patients with a mean age of 44.0±11.4 years, and 81.9% female. The primary outcome was achieved in 74.2% of patients, with a significant (p < 0.001) reduction in headache frequency, pain severity, analgesic use, and improvement in QoL. Age and duration of migraine were significant predictors of achieving a ≥ 50% reduction in headache frequency after therapy (OR = 0.955; p = 0.009) and (OR = 0.965; p = 0.025), respectively. Treatment compliance was observed in 76.2% of patients, and 24.5% discontinued treatment. Constipation was the most commonly reported AEs (6.0%), and conservative management was the most common approach to managing AEs. Conclusion Erenumab was effective in reducing the frequency and severity of migraine attacks and improving QoL, and safe with manageable AEs in a real-world setting in Kuwait. Further research is needed to better understand erenumab’s effectiveness and safety in different populations and settings, as well as to compare it with other migraine prophylactic treatments.

Efficacy of oral and non‐oral migraine prophylactic treatment on self‐reported subjective sleep quality in migraine patients with sleep problems: A review and meta‐analysis

Efficacy of oral and non‐oral migraine prophylactic treatment on self‐reported subjective sleep quality in migraine patients with sleep problems: A review and meta‐analysis

The Effect of Calcitonin Gene-Related Peptide Monoclonal Antibodies on Quality of Life among Migraine Patients: Pilot Study at the Hospital of Lithuanian University of Health Sciences Kaunas Clinics.

Migraine has a negative impact on patients' quality of life, with the frequency of attacks being associated with greater disability and poorer health status. Frequent migraine-type headaches require prophylactic treatment, which has so far been of limited effectiveness until advent of calcitonin gene-related peptide (CGRP) monoclonal antibody. A prospective analysis was conducted of data from 41 migraine patients who experienced 4 or more monthly migraine days (MMD) longer than three months. At the beginning of the study, treatment with monoclonal antibodies against CGRP (fremanezumab 225 mg or erenumab 70 or 140 g per month) was prescribed according to the indications. The effect of the medications was evaluated after 3-month period. The mean age of patients was 37.17 (±11.78) years. It was found that 17 patients (41.5%) had episodic migraine (EM) and 24 (58.5%) had chronic migraine (CM). Fremanezumab was prescribed to 26 patients (63.4%) and erenumab to 15 patients (36.6%); among the latter, 13 patients used 70 mg/month and 2 patients used 140 mg/month. Three months after treatment, CM changed to EM for 19 patients (79.2%), 27 patients (65.9%) had ≥50% reduction in the number of MMD and total migraine disability assessment (MIDAS) score was reduced by >50% in 31 patients (75.6%). Also, all areas of quality of life of patients were improved after 3 months continued treatment compared to baseline. For more than half the patients using fremanezumab or erenumab after 3-month period, MMD decreased by ≥50% and total MIDAS score by >50 points. All areas of quality of life were improved after prophylactic treatment of migraine.

Reliability, validity, and responsiveness of the Arabic version of HIT-6 questionnaire in patients with migraine indicated for preventive therapy: A multi-center study.

The Headache Impact Test (HIT-6) is an important patient-reported outcome measure (PROM) in migraine prevention trials. This study aimed to (i) assess the reliability and validity of the Arabic version of HIT-6 in Arabic-speaking patients experiencing migraine, and (ii) evaluate the responsiveness of HIT-6 following migraine preventive therapy. In this prospective study, patients with migraine (n = 145) were requested to fill out a headache diary, the Arabic version of HIT-6, and Migraine Disability Assessment Scale (MIDAS) at two time points (baseline and 3 months after initiation of prophylactic treatment). Some respondents (n = 73) were requested to fill out HIT-6 again 1 week from the baseline for test-retest reliability. The intensity of migraine headache attacks was evaluated using the Visual Analogue Scale (VAS). An anchor-based method was used to establish the minimal important change (MIC) value and responsiveness of HIT-6. The total scores of HIT-6 were significantly correlated to a fair degree with MIDAS (r = 0.41), as well as VAS (r = 0.53), and monthly migraine days (r = 0.38) at the baseline while at the follow-up (after 3 months), the correlations were of moderate degree with MIDAS scores (r = 0.62) and monthly migraine days (r = 0.60; convergent validity). Reliability estimates of the Arabic HIT-6 were excellent (Cronbach's α = 0.91 at baseline and 0.89 at follow-up). The average measure interclass correlation coefficient (ICC) value for the test-retest reliability was 0.96 (95% confidence interval = 0.94-0.98, p < 0.001). The HIT-6 total score is sensitive to change, being significantly reduced after prophylactic treatment compared to before (effect size = 1.5, standardized response mean = 1.3). A reduction from baseline of 4.5 on HIT-6 showed the highest responsiveness to predict improvement with an area under the curve equal to 0.66, sensitivity of 80%, specificity of 45%, and significance at 0.021. Changes in the HIT-6 total score were positively correlated with changes in monthly migraine days (r = 0.40) and VAS scores (r = 0.69) but not with changes in the score of MIDAS (r = 0.07). The Arabic version of HIT-6 is valid, reliable, and sensitive to detect clinical changes following migraine prophylactic treatment with a MIC of 4.5 points.

Napex acupoint thread-embedding combined with metoprolol tartrate tablet for prophylactic treatment of migraine without aura: a randomized controlled trial.

To observe the efficacy of napex acupoint thread-embedding combined with metoprolol tartrate tablet for prophylactic treatment of migraine without aura, and to compare its efficacy with simple napex acupoint thread-embedding and simple metoprolol tartrate tablet. A total of 105 patients with migraine without aura were randomized into a combination group (35 cases, 5 cases dropped out), a thread-embedding group (35 cases, 4 cases dropped out) and a western medication group (35 cases, 2 cases dropped out). In the thread-embedding group, napex acupoint thread-embedding was applied at bilateral Fengchi (GB 20) and points of 1.5 cun nearby to the lower edge of spinous process of cervical 2. In the western medication group, metoprolol tartrate tablet was given orally, 12.5 mg a time, twice a day. In the combination group, napex acupoint thread-embedding combined with oral metoprolol tartrate tablet was delivered. The treatment of 8 weeks was required in the 3 groups. The days of headache attacks, frequency of headache attacks, headache severity (visual analogue scale [VAS] score) and the migraine specific quality of life questionnaire version 2.1 (MSQ) score were observed during baseline period (4 weeks before treatment to before treatment), observation period (1-4 weeks and 5-8 weeks in treatment) and follow-up period (1-4 weeks after treatment completion) respectively, the proportions of the days of headache attacks/frequency of headache attacks relieved by 50% were calculated, and the safety was evaluated in the 3 groups. During the observation period and the follow-up period, the days of headache attacks, frequency of headache attacks and headache VAS scores in the 3 groups were reduced compared with those of the baseline period (P<0.05). During the observation period and the follow-up period, the days of headache attacks and the frequency of headache attacks in the combination group were lower than those in the thread-embedding group and the western medication group (P<0.05); during the observation period (1-4 weeks in treatment), the headache VAS scores in the combination group and the thread-embedding group were lower than that in the western medication group (P<0.05); during the observation period (5-8 weeks in treatment) and the follow-up period, the headache VAS scores in the combination group were lower than those in the thread-embedding group and the western medication group (P<0.05). During the observation period and the follow-up period, the scores of role restriction, role prevention and emotion function of MSQ in the combination group were increased compared with those of the baseline period (P<0.05); during the observation period (5-8 weeks in treatment) and the follow-up period, the role prevention scores of MSQ in the thread-embedding group and the western medication group were increased compared with those of the baseline period (P<0.05); during the follow-up period, the emotion function scores of MSQ in the thread-embedding group and the western medication group were increased compared with those of the baseline period (P<0.05). During the observation period and the follow-up period, the scores of role restriction, role prevention and emotion function of MSQ in the combination group were higher than those in the thread-embedding group and the western medication group (P<0.05). There was no statistical difference in the proportions of the days of headache attacks/frequency of headache attacks relieved by 50% among the 3 groups (P>0.05), and there were no serious adverse reactions in the 3 groups. Napex acupoint thread-embedding combined with metoprolol tartrate tablet, simple napex acupoint thread-embedding and simple metoprolol tartrate tablet all can reduce the days of headache attacks and the frequency of headache attacks, relieve headache severity and improve the quality of life in patients with migraine without aura. Napex acupoint thread-embedding combined with metoprolol tartrate tablet has a better effect.

Anti-CGRP-based Migraine Medications: A Comprehensive Overview

In the early 1990s, the neuropeptide calcitonin gene-related peptide (CGRP) was identified as a key messenger in the pathophysiology of migraine and emerged as a treatment target, fundamentally transforming our approach to migraine therapy. While previous prophylactic drugs were non-specific and often caused intolerable side effects, the discovery of CGRP marked the advent of a new era in migraine treatment. The two main classes of CGRP-specific migraine treatments are monoclonal antibodies that bind to CGRP or the CGRP receptor, and CGRP receptor antagonists, the so-called gepants. Extensive clinical trials have conclusively demonstrated the safety, tolerability, and efficacy of monoclonal CGRP(-receptor) antibodies in the prophylactic treatment of both episodic and chronic migraine. The same positive results apply to the use of various gepants. They have proven to be not only an effective alternative to triptans in acute migraine therapy but also promising options for continuous use as prophylactic treatments. In this review, we aim to present the current state of research on CGRP-specific migraine therapy and insights in real-world data from the first years after their launch in clinical practice.

Is erenumab an efficient alternative for the prevention of episodic and chronic migraine in Spain? Results of a cost-effectiveness analysis

BackgroundThe reimbursement of erenumab in Spain and other European countries is currently restricted because of the cost of this novel therapy to patients with migraine who have experienced previous failures to traditional preventive treatments. However, this reimbursement policy should be preferably based on cost-effectiveness studies, among other criteria. This study performed a cost-effectiveness analysis of erenumab versus topiramate for the prophylactic treatment of episodic migraine (EM) and versus placebo for chronic migraine (CM).MethodsA Markov model with a 10-year time horizon, from the perspective of the Spanish National Healthcare System, was constructed based on data from responder and non-responder patients. A responder was defined as having a minimum 50% reduction in the number of monthly migraine days (MMD). A hypothetical cohort of patients with EM with one or more prior preventive treatment failures and patients with CM with more than two treatment failures was considered. The effectiveness score was measured as an incremental cost per quality-adjusted life year (QALY) gained and cost per migraine day (MD) avoided. Data from clinical outcomes and patient characteristics were obtained from erenumab clinical trials (NCT02066415, STRIVE, ARISE, LIBERTY and HER-MES). Deterministic and probabilistic sensitivity analyses were performed to validate the robustness of the model.ResultsAfter a 10-year follow-up, the estimated QALYs were 5.88 and 6.11 for patients with EM treated with topiramate and erenumab, respectively. Erenumab showed an incremental cost per patient of €4,420 vs topiramate. For CM patients, erenumab resulted in 0.756 QALYs gained vs placebo; and an incremental cost of €1,814. Patients treated with erenumab achieved reductions in MD for both EM and CM (172 and 568 MDs, respectively). The incremental cost per QALY gained with erenumab was below the Spanish threshold of €30,000/QALY for both health and societal perspectives (EM €19,122/QALY and CM €2,398/QALY).ConclusionsErenumab is cost-effective versus topiramate as a preventive treatment for EM and versus placebo for patients with CM from the perspective of the Spanish National Health System.

Eptinezumab for the preventive treatment of episodic and chronic migraine: a narrative review.

Eptinezumab, a monoclonal antibody that targets calcitonin gene-related peptide (CGRP), was recently approved in Europe for the prophylactic treatment of migraine in adults who have at least four migraine days a month. Eptinezumab is administered by intravenous infusion every 12 weeks. During recent months, a considerable amount of evidence from eptinezumab trials has been published. The aim of this review is to describe the existing evidence on the tolerability, safety and efficacy of eptinezumab in patients with migraine. Data from randomized (PROMISE-1, PROMISE-2, RELIEF and DELIVER) and open-label (PREVAIL) phase 3 clinical trials have demonstrated the favorable effect of eptinezumab in migraine symptoms from first day of treatment. These studies showed that eptinezumab results in an overall reduction in mean monthly migraine days (MMDs), increases in the ≥50% and ≥ 75% migraine responder rates (MRRs) and improvements in patient-reported outcome measures in both patients with episodic migraine (EM) and with chronic migraine (CM), including patients who failed previous preventive treatments. The RELIEF trial also showed that eptinezumab, within 2 h of administration, reduced headache pain, migraine-associated symptoms and acute medication use when administered during a migraine attack. Eptinezumab benefits manifested as early as day 1 after dosing and with the subsequent doses lasted up to at least 2 years. Treatment-emergent adverse events reported by ≥2% of patients included upper respiratory tract infection and fatigue. Current evidence demonstrates that eptinezumab has a potent, fast-acting, sustained migraine preventive effect in patients with EM and CM. Eptinezumab has also shown to be well tolerated, supporting its use in the treatment of patients with migraine and inclusion in the current migraine therapeutic options.

Indian Consensus on the Role of Amitriptyline in Migraine Prophylaxis.

Migraine is a globally prevalent neurological disorder. Amitriptyline, a tricyclic antidepressant, has shown potential as a prophylactic treatment for migraine; however, its role as a first-line medication has been debated. A modified Delphi method was used to develop consensus statements on migraine and its management. The literature review identified knowledge gaps, and two survey rounds were conducted among a panel of experts. Consensus was reached for 12 out of 23 initial survey questions, whereas no consensus was reached for four questions after the deliberation in the second round. The results showed that migraine is highly prevalent among women aged 15-35 years in India. Amitriptyline is an effective monotherapy for prophylactic migraine management, with a recommended initial dose of 5-10 mg. A gradual titration over six months achieves optimal results. Amitriptyline is also safe for managing catamenial migraine and can be used at lower doses during pregnancy to alleviate symptoms. The outcomes of this study emphasize that amitriptyline should be considered as a primary prophylactic treatment for migraine because of its efficacy and safety. The evidence-based consensus achieved is intended to serve as guidance for healthcare practitioners in India, and it is anticipated that such adoption will lead to improvement in patient outcomes and an enhancement in the quality of life for those affected by migraines.

The Application of Botulinum Toxin in the Prophylactic Treatment of Migraine

Abstract Introduction: Migraine is a common disorder that affects about 2% of the general population, with a prevalence of 7% in men, 24% in women and 4% in children. Migraine is the fourth most disabling condition among women and the seventh most disabling worldwide. It is characterized by paroxysmal, throbbing headaches, often unilateral, accompanied by hypersensitivity to noise, light, nausea and vomiting. Migraine is divided into episodic and chronic, with chronic meaning headache for at least 15 days a month for more than 3 months, with 8 migraine days. Treatment includes non-pharmacological and pharmacological methods, but often ineffective and fraught with side effects. Chronic migraine can lead to significant disability. Material and methods: The purpose of this article is to discuss the treatment of migraine with botulinum toxin. Information was collected from the English-language databases Google Scholar, Scopus and PubMed. Results :Onabotulinum toxin A, approved for the treatment of migraine, works by blocking acetylcholine release at the synapse level, leading to reversible flaccid paralysis and blocking neurotransmitters such as CGRP. Injection sites include peri-cranial and neck muscles, allowing the toxin to be transported to the meninges and trigeminal ganglion. In recent years, injections near the cranial sutures have been preferred. BTX-A therapy has shown efficacy in reducing the frequency and severity of migraine pain, with fewer side effects compared to topiramate. Side effects, such as hematoma or ptosis, are rare and their frequency decreases with subsequent sessions. The cost of migraine treatment is high, but botulinum toxin reduces headache days and is cost-effective.

Comparison between the effectiveness of three prophylactic drugs for vestibular migraine; cinnarizine, propranolol, and topiramate: prospective study

BackgroundVestibular migraine (VM) is considered one of the most common causes of episodic vertigo. Acute attacks may interfere or hinder daily activities, and hence decrease the quality of life. Accordingly, this study was designed to evaluate and compare the effectiveness of Cinnarizine, Propranolol, and Topiramate as prophylactic treatment for vestibular migraine, in order to decrease the occurrence of acute attacks. Several medications have been proposed as a prophylactic treatment, but their benefit is still a vast field of study.MethodsForty-five subjects were diagnosed with vestibular migraine. They were divided into 3 groups; each group either received Cinnarzine, Propranolol, or Topiramate. All patients were submitted to thorough history taking for headache and vertiginous attacks, Dizziness Handicap Inventory questionnaire (DHI) -Arabic version, visual analog scale, videonystagmography, and computerized dynamic posturography (CDP) before and after receiving the treatment by 3 months.ResultsTopiramate was significantly superior in reducing the frequency and severity of headache attacks. The three drugs showed improvement but with no significant difference as regards duration and frequency of vertiginous attacks, DHI scores, and CDP. Only 5 patients had non-serious temporary side effects.ConclusionsThe three drugs were effective for ameliorating vertiginous attacks in vestibular migraine patients, but Topiramate was better in the 25 mg twice daily dose.

Tai Chi for the prophylaxis of episodic migraine: protocol of a non-inferiority randomized controlled trial with mechanism exploration

BackgroundMigraine is a complex neurovascular disorder with considerable clinical, social and economic issues. Tai chi has the potential to be an alternative prophylactic treatment for migraine with high safety since the adverse effects and limited efficacy of available medications.AimsThe proposed study aims to compare the prophylaxis efficacy of 24-week Tai Chi training on migraine attacks with the standard prophylactic medication; and to explore the mechanism of Tai Chi in preventing migraine attacks by analyzing the associations between changes of migraine attacks and changes of neurovascular functions and inflammatory makers.MethodThis is a two-arm parallel non-inferiority randomized controlled trial. In total 220 Hong Kong Chinese women aged 18–65 years with diagnosis of episodic migraine will be recruited and randomized to either the Tai Chi training group or the standard prophylactic medication group with 1:1 ratio, and receive the 24 weeks of modified 33-short form Yang-style Tai Chi training and the standard prophylactic medications, respectively. A 24-week follow-up will be implemented for both groups. For efficacy examination, the primary outcome was the frequency of migraine attacks measured by the migraine diary; and for the mechanism exploration, the primary outcome was the volume and number of white matter hyperintensity (WMH) measured by magnetic resonance imaging (MRI). The measurements will be conducted at the baseline, 24th weeks, and 48th weeks. Linear mixed model will be adopted to comprehensively analyze the changes of variables within and between groups.DiscussionGiven the importance of reducing disease burden and financial cost of migraine attacks, the findings of this study will provide new insights regarding the role of Tai Chi in alleviating migraine burden and further shed light on the mechanism action of Tai Chi on preventing headache attacks.Trial registrationClinicalTrials.gov NCT05690737.

Predictors of galcanezumab response in a real-world study of Korean patients with migraine

To assess factors associated with galcanezumab response in a real-world study of Korean patients with migraine. Predictors of the efficacy of monoclonal antibodies targeting calcitonin gene-related peptide (CGRP) or its receptor (anti-CGRP(-R) mAb) have been rarely investigated in Asians. We prospectively recruited and followed up patients with migraine who received monthly galcanezumab treatment in a single university hospital from June 2020 to October 2021. We defined the treatment response with ≥ 50% reduction in moderate/severe headache days in the 3rd month of treatment compared to baseline. Responders and non-responders were compared in terms of demographics, disease characteristics and severity, and previous response to migraine prophylactic treatments. Potential predictors of anti-CGRP(-R) mAb response were tested by using the univariable and multivariable logistic regression analyses. Among 104 patients (81.7% female; mean age 42.0 ± 13.02; 76.9% chronic migraine; and 45.5% medication overuse headache) included, 58 (55.7%) were responders. Non-responders had more chronic migraine, medication overuse headache, monthly headache days, days with acute medication, and daily headaches (i.e. chronic migraine persisting everyday without remission). The multivariable logistic analysis showed chronic migraine (OR 0.05 [95% CI 0.00–0.82], p = 0.036) and the number of previously failed preventive medication classes (OR 0.55 [95% CI 0.33–0.92], p = 0.024] were independently associated with treatment response. Chronic migraine and multiple failures from preventive medication are associated with poor galcanezumab response. Further studies are needed to investigate if earlier treatment before disease chronification or multiple failures may lead to a greater therapeutic gain from anti-CGRP(-R) mAb treatment.

The Effect of Coenzyme Q10 as a Prophylactic Treatment in Episodic Migraine

Aim: Migraine is a neurological disorder characterized by recurring and often severe headaches. The aim of this study was to evaluate the effectiveness of coenzyme Q10 (CoQ10) in episodic migraine prophylaxis. Material and Methods: In a prospective follow-up study, 80 patients with episodic migraine were enrolled according to the International Classification of Headache Disorders 3rd edition and divided into two groups. One group consisted of 40 patients who received CoQ10 oral 200 mg twice daily as monotherapy for three months, while the other group consisted of 40 patients who received CoQ10 as an adjunct therapy in combination with other prophylactic antimigraine drugs. The Migraine Disability Assessment (MIDAS) questionnaire was administered to both groups before and after three months of therapy. Throughout the three-month therapy period, patients recorded daily symptoms, allowing for observation of changes in symptom severity, number, and duration of attacks from baseline. Results: Both groups that received CoQ10 supplementation exhibited positive responses. The group receiving adjunct therapy showed a statistically more significant reduction in the MIDAS (p&amp;lt;0.001), duration (p&amp;lt;0.001), and frequency (p&amp;lt;0.001) of attacks compared to the monotherapy group. Vomiting (p&amp;lt;0.001) in the adjunct therapy group completely disappeared and sound sensitivity (p=0.002) showed a dramatic response to treatment. Conclusion: CoQ10 appears to have more beneficial effects as an adjunct than monotherapy in reducing the duration, frequency, and presenting symptoms such as nausea, vomiting, and light sensitivity, in addition to sound sensitivity that responded only to adjunct therapy than monotherapy among Iraqi patients with episodic migraine.

Effectiveness of Acupuncture for Prophylactic Treatment of Migraine: A Systematic Review and Bayesian Network Meta-Analysis.

It is aimed to evaluate the effectiveness and provide evidence-based medical support for acupuncture as a prophylactic treatment for migraines. Randomized controlled trials (RCTs) from inception to April 2022 are included in 14 databases. Pairwise meta-analysis is conducted using STATA software V14.0, while Windows Bayesian Inference Using Gibbs Sampling (WinBUGS V.1.4.3) is applied to generate Bayesian Network Meta-analysis (NMA) using Markov chain Monte Carlo algorithm. Forty RCTs are included, with 4405 participants. The effectiveness of six acupuncture techniques, three types of prophylactic drugs, and psychotherapy are compared and ranked. Acupuncture outperformed prophylactic drugs in terms of diminishing visual analog scale (VAS) score, migraine attack frequency, and days during the treatment and at the 12-week follow-up. At the 12-week follow-up, the effectiveness of various interventions is ranked as follows: manual acupuncture (MA) > electroacupuncture (EA) > calcium antagonists (CA) in reducing VAS score; MA > EA > CA in reducing migraine attack frequency; MA > EA > β-receptor blocker and CA in reducing headache attack days. Acupuncture is a promising treatment for migraine prevention. The best option of acupuncture for improving various migraine outcomes has changed over time. However, the quality of included trials and NMA inconsistency limited the credibility of the conclusion.
