Comparative effect of electroacupuncture with different frequency on headache attacks in migraine outpatients: study protocol for a randomised placebo-controlled trial.
Ontology highlight
ABSTRACT: Background
Headache attacks severely impaired life quality and increase the economic burden of migraineurs. Electroacupuncture (EA) has been used worldwidely to treat several pain-related diseases including migraines. However, whether EA with low or high frequency exerts a distinct analgesic effect remains unknown and needs further study.Methods/design
This study is a randomised, single-blinded, placebo-controlled trial with three parallel arms. A total of 144 migraine outpatients will be randomly allocated to the 2 Hz EA group, 100 Hz EA group and placebo control group. The duration of the trial is 20 weeks, including a 4-week-long baseline assessment period (weeks - 4-0), a 4-week-long treatment period (weeks 1-4) and a 12-week-long follow-up period (weeks 5-16). Twelve treatment sessions will be performed over a 4-week period (weeks 1-4). The primary outcome will be measured by the frequency of migraine attacks in the past 4 weeks at the end of week 4 post-randomisation. The secondary outcome will be measured by the frequency of migraine attacks in the past 4 weeks at the end of weeks 8, 12 and16 post-randomisation; number of days with migraine; dosage of ibuprofen; the scores of visual analogue scale (VAS); Self-Rating Anxiety Scale (SAS); Self-Rating Depression Scale (SDS); and Migraine Specific Quality of Life questionnaire (MSQ) in the past 4 weeks at the end of weeks 4, 8, 12 and 16 post-randomisation. Safety assessment, compliance and blinding evaluation will be carried out at the end of week 16 post-randomisation.Discussion
The recruitment will be started on 1 June 2021 and expected to finish on 31 May 2023. We aimed to clarify the dominant frequency of EA on headache attacks in a migraineur.Trial registration

Project description:BackgroundThis study evaluates the accuracy of an automated classification tool of single attacks of the two major primary headache disorders migraine and tension-type headache used in an electronic headache diary.MethodsOne hundred two randomly selected reported headache attacks from an electronic headache-diary of patients using the medical app M-sense were classified by both a neurologist with specialisation in headache medicine and an algorithm, constructed based on the ICHD-3 criteria for migraine and tension-type headache. The level of agreement between the headache specialist and the algorithm was compared by using a kappa statistic. Cases of disagreement were analysed in a disagreement validity assessment.ResultThe neurologist and the algorithm classified migraines with aura (MA), migraines without aura (MO), tension-type headaches (TTH) and non-migraine or non-TTH events. Of the 102 headache reports, 86 cases were fully agreed on, and 16 cases not, making the level of agreement unweighted kappa 0.74 and representing a substantial level of agreement. Most cases of disagreement (12 out of 16) were due to inadvertent mistakes of the neurologist identified in the disagreement validity assessment. The second most common reason (3 out of 16) was insufficient information for classification by the neurologist.ConclusionsThe substantial level of agreement indicates that the classification tool is a valuable instrument for automated evaluation of electronic headache diaries, which can thereby support the diagnostic and therapeutic clinical processes. Based on this study’s results, additional diagnostic functionalities of primary headache management apps can be implemented. Finally, future research can use this classification algorithm for large scale database analysis for epidemiological studies.

Project description:BackgroundSeveral psychological cofactors of migraine have been identified, but relationships to different headache parameters (e.g., headache frequency vs. headache-related disability) are only incompletely understood.MethodsWe cross-sectionally assessed 279 migraine patients at their first presentation at our tertiary headache center. We obtained headache and acute medication frequency, pain intensity, the Migraine Disability Assessment Scale (MIDAS), and the Pain Disability Index (PDI) as headache-related outcomes as well as scores of the Hospital Anxiety and Depression Scale (HADS), the Pain Catastrophizing Scale (PCS), Pain-Related Control Scale (PRCS), and Avoidance Endurance Questionnaire (AEQ) as psychological factors.ResultsLinear regression models revealed the highest associations of the psychological factors with the PDI (adjusted R2 = 0.296, p < 0.001, independent predictors: PCS, AEQ social avoidance, depression) followed by the MIDAS (adjusted R2 = 0.137, p < 0.001, predictors: depression, AEQ social avoidance) and headache frequency (adjusted R2 = 0.083, p < 0.001, predictors: depression, AEQ humor/distraction). Principal component analysis corroborated that psychological factors were preferentially associated with the PDI, while the MIDAS loaded together with headache frequency.ConclusionOur results suggest that psychological factors are more strongly associated with the subjective degree of headache-related disability measured by the PDI than with the days with disability (MIDAS) or the more objective parameter of headache frequency. This once again highlights the need for comprehensive assessment of migraine patients with different headache parameters and the need for considering psychological treatment, especially in patients with high disability.

Project description:ObjectiveThis post hoc analysis in patients medically diagnosed with chronic migraine (CM) and medication-overuse headache (MOH) evaluated reductions in the use of acute headache medication (AHM) and sustained changes in the diagnostic status of CM and MOH following eptinezumab treatment in the PROMISE-2 study.BackgroundEptinezumab, a monoclonal antibody that inhibits calcitonin gene-related peptide, is approved in the United States for the preventive treatment of migraine. A previous analysis showed that eptinezumab reduced monthly migraine days and was well tolerated in the subgroup of PROMISE-2 patients diagnosed with both CM and MOH.MethodsThe phase 3, double-blind, placebo-controlled PROMISE-2 study (NCT02974153) randomized adults with CM to eptinezumab 100 mg, 300 mg, or placebo (administered intravenously every 12 weeks for up to two doses). MOH was prospectively diagnosed at screening by trained physicians based on 3 months of medication history and International Classification of Headache Disorders-3β criteria. This post hoc analysis evaluated changes in total and class-specific days of AHM usage, the percentage of patients using AHM at or above MOH diagnostic thresholds, and the percentage of patients experiencing monthly headache and migraine day frequency below diagnostic thresholds for MOH and/or CM.ResultsIn PROMISE-2, 431/1072 (40.2%) patients with CM were diagnosed with MOH (eptinezumab 100 mg, n = 139; 300 mg, n = 147; placebo, n = 145) and were included in this analysis. Total monthly AHM use decreased from 20.6 days/month at baseline to 10.6 days/month over 24 weeks of treatment (49% decrease) with eptinezumab 100 mg, from 20.7 to 10.5 days/month (49% decrease) with eptinezumab 300 mg, and from 19.8 to 14.0 days/month (29% decrease) with placebo. Numerically greater decreases from baseline with eptinezumab were also observed for individual drug classes. In each study month, the percentages of patients who were below MOH thresholds were numerically higher for both eptinezumab doses compared with placebo, as were the percentages of patients experiencing headache and migraine frequency below CM thresholds. Of patients with available data across the entire treatment period, 29.0% (58/200) of patients treated with eptinezumab stopped meeting and remained below diagnostic thresholds for both CM and MOH during Weeks 1-24, as well as 6.3% (6/96) of patients who received placebo.ConclusionsAcross 24 weeks of treatment, eptinezumab reduced AHM use in patients diagnosed with CM and MOH. More than one-fourth (29%) of patients treated with eptinezumab did not meet the diagnostic thresholds for either CM or MOH for the entire treatment period.

Project description:Information provided to patients is thought to influence placebo and drug effects. In a prospective, within-subjects, repeated-measures study of 66 subjects with episodic migraine, we investigated how variations in medication labeling modified placebo and drug effects. An initial attack with no treatment served as a control. In six subsequent migraine attacks, each participant received either placebo or Maxalt (10-mg rizatriptan) administered under three information conditions ranging from negative to neutral to positive (told placebo, told Maxalt or placebo, told Maxalt) (N = 459 documented attacks). Treatment order was randomized. Maxalt was superior to placebo for pain relief. When participants were given placebo labeled as (i) placebo, (ii) Maxalt or placebo, and (iii) Maxalt, the placebo effect increased progressively. Maxalt had a similar progressive boost when labeled with these three labels. The efficacies of Maxalt labeled as placebo and placebo labeled as Maxalt were similar. The efficacy of open-label placebo was superior to that of no treatment. Relative to no treatment, the placebo, under each information condition, accounted for more than 50% of the drug effect. Increasing "positive" information incrementally boosted the efficacy of both placebo and medication during migraine attacks. The benefits of placebo persisted even if placebo was honestly described. Whether treatment involves medication or placebo, the information provided to patients and the ritual of pill taking are important components of care.

Project description:BackgroundMigraine is a disabling neurologic disease that can fluctuate over time in severity, frequency, and acute medication use. Harris Poll Migraine Report Card was a US population-based survey to ascertain quantifiable distinctions amongst individuals with current versus previous high-frequency headache/migraine and acute medication overuse (HFM+AMO). The objective of this report is to compare self-reported experiences in the migraine journey of adults with HFM+AMO to those who previously experienced HFM+AMO but currently have a sustained reduction in headache/migraine frequency and acute medication use.MethodsAn online survey was available to a general population panel of adults (≥18 years) with migraine per the ID Migraine™ screener. Respondents were classified into "current HFM+AMO" (within the last few months had ≥8 headache days/month and ≥10 days/month of acute medication use; n=440) or "previous HFM+AMO" (previously had HFM+AMO, but within the last few months had ≤7 headache days/month and ≤9 days/month of acute medication use; n=110). Survey questions pertained to demographics, diagnosis, living with migraine, healthcare provider (HCP) communication, and treatment.ResultsParticipants in the current HFM+AMO group had 15.2 monthly headache days and 17.4 days of monthly acute medication use in last few months compared to 4.2 and 4.1 days for the previous HFM+AMO group, respectively. Overall, current preventive pharmacologic treatment use was low (15-16%; P>0.1 for current vs previous) in both groups. Previous HFM+AMO respondents reported better current acute treatment optimization. More respondents with current (80%) than previous HFM+AMO (66%) expressed concern with their current health (P<0.05). More than one-third of both groups wished their HCP better understood their mental/emotional health (current 37%, previous 35%; P>0.1 for current vs previous) and 47% (current) to 54% (previous) of respondents worried about asking their HCP too many questions (P>0.1 for current vs previous).ConclusionApart from optimization of acute medication, medical interventions did not significantly differentiate between the current and previous HFM+AMO groups. Use of preventive pharmacological medication was low in both groups. Adults with current HFM+AMO more often had health concerns, yet both groups expressed concerns of disease burden. Optimization of acute and preventive medication and addressing mental/emotional health concerns of patients are areas where migraine care may impact outcomes regardless of their disease burden.

Project description:BACKGROUND:Galcanezumab is a novel monoclonal antibody that target to calcitonin gene-related peptide (CGRP). It has been tested for the preventive treatment of migraine and episodic cluster headache by multiple randomized clinical trials (RCTs) and have been found to reduce headache frequency. METHODS:We systematically searched PubMed and Embase on Cochrane Central Register of Controlled Trials (CENTRAL) from the earliest date to August 1, 2019. Relative risk (RR) and weighted mean difference (WMD) were used to evaluate clinical outcomes. RESULTS:Seven studies were pooled with 3889 patients. Subcutaneous injection of Galcanezumab at 120?mg, 240?mg leads to a statistically significant response rate for the treatment of migraine compared with placebo (120?mg: RR?=?1.51; 95% CI, 1.33 to 1.70; P?<?0.001; 240?mg: RR?=?1.58; 95% CI, 1.43 to 1.76; P?<?0.001). Among them, 120?mg group has the same treatment efficacy with 240?mg group (50% response: RR?=?1.06; 95% CI, 0.92 to 1.22; P?=?0.425; 75% response: RR?=?1.07; 95% CI, 0.94 to 1.23; P?=?0.301; 100% response; RR?=?1.06; 95% CI, 0.81 to 1.37; P?=?0.682; MHD: RR?=?-?0.08; 95% CI, -?0.55 to -?0.40; P?=?0.748) while related to a lower risk for adverse events for the treatment of migraine (120?mg RR?=?1.06; 95% CI, 0.99 to 1.14; P?=?0.084; 240?mg: RR?=?1.17; 95% CI, 1.09 to 1.25; P?<?0.001). 300?mg per month galcanezumab is effective for the prevention of episodic cluster headache measured by at least 50% reduction of cluster headache frequency at week 3 (RR?=?1.36; 95% CI, 1.00-1.84; P?=?0.048). CONCLUSIONS:Use of galcanezumab is related to a significantly reduced monthly headache frequency compared with placebo for the treatment of migraine and episodic cluster headache, 120?mg has the same treatment efficacy with 240?mg group while related to a lower risk for adverse effects for the treatment of migraine. 300?mg per month galcanezumab is effective for the prevention of episodic cluster headache with no significantly increased adverse events.

Project description:Migraineurs show hypersensitivity to sensory stimuli at various stages throughout the migraine cycle. A number of putative processes have been implicated including a dysfunction in the descending pain modulatory system in which the periaqueductal gray (PAG) is considered to play a crucial role. Recurring migraine attacks could progressively perturb this system, lowering the threshold for future attacks, and contribute to disease chronification. Here, we investigated PAG connectivity with other brain regions during a noxious thermal stimulus to determine changes in migraineurs, and associations with migraine frequency. 21 episodic migraine patients and 22 matched controls were included in the study. During functional MRI, a thermode was placed on the subjects' temple delivering noxious and non-noxious heat stimuli. A psychophysiological interaction (PPI) analysis was carried out to examine pain-induced connectivity of the PAG with other brain regions. The PPI analysis showed increased PAG connectivity with the S1 face representation area and the supplementary motor area, an area involved with pain expectancy, in patients with higher frequency of migraine attacks. PAG connectivity with regions involved with the descending pain modulatory system (i.e., prefrontal cortex) was decreased in the migraineurs versus healthy individuals. Our results suggest that high frequency migraineurs may have diminished resistance to cephalic pain and a less efficient inhibitory pain modulatory response to external stressor (i.e., noxious heat). The findings support the notion that in migraine there is less effective pain modulation (viz., decreased pain inhibition or increased pain facilitation), potentially contributing to increased occurrence of attacks/chronification of migraine.

Project description:BackgroundMigraine is considered a disease with diurnal and 24 h pattern, though the existence of a prevalent circadian rhythm associated to migraine frequency and severity is still not clear. This observational cross-sectional study aimed to: 1. Assess the circadian rhythm of migraine attacks onset in a large patients' population selected in a headache center and including episodic and chronic migraine 2. Analyze the principal characteristic of the different onset time groups 3. Verify if migraine features, particularly those associated to chronic and disabling migraine, could be discriminant factors for time of onset group.MethodsWe selected 786 consecutive migraine outpatients, who correctly completed the headache diaries for 3 consecutive months and who fulfilled the diagnosis of migraine without aura-MO, migraine with typical aura alone or associated to migraine without aura - MO/MA and chronic migraine - CM. For the time of headache onset, we considered four time slots, from 6 to 12 am (morning), from 1 to 6 pm (afternoon), from 7 to 11 pm (evening), from 12 pm to 5 am (night), and an additional category named "any time". Each time slot included the 60 min preceding the next one (e.g. an onset at 12.30 am was included in 6-12 am time slot). We evaluated in all patients the pericranial tenderness, anxiety and depression tracts, headache-related disability, sleep features, quality of life, allodynia and fatigue.ResultsWe scored a total of 16,578 attacks, distributed in the entire day. The most of patients, including CM, satisfied the criteria for the "any time" onset. Night onset was significantly less represented in the MA/MO group. Patients with prevalent night onset were significantly older, with longer migraine history and shorter sleep duration. Age and illness duration were the variables discriminating the different onset time groups.ConclusionsThe most of migraine patients do not report a specific circadian profile of attacks occurrence. Frequent migraine, severe disability, psychopathological tracts as well as central sensitization signs, do not match with a specific circadian rhythm of attacks onset. Night onset migraine seems to be an age related feature, emerging in the course of the disease.

Project description:Background: Migraines with aura have been associated with suicide in adolescents and young adults, but the association between suicide and migraine frequency has not been determined. This study investigated suicidal ideation and suicide attempts among patients with varying frequencies of migraines, with and without auras. Methods: This cross-sectional study analyzed 528 patients aged between 20 and 60 years from a headache outpatient clinic in Taiwan. All patients completed a set of questionnaires, including a demographic questionnaire, the Migraine Disability Assessment questionnaire, the Hospital Anxiety and Depression Scale, the Beck Depression Inventory, and the Pittsburgh Sleep Quality Index. Suicide risk was evaluated by self-reported lifetime suicidal ideation and attempts. Patients were divided into low-frequency (1-4 days/month), moderate-frequency (5-8 days/month), high-frequency (9-14 days/month), and chronic (≥15 days/month) migraine groups. The association between migraine frequency and suicidality was investigated using multivariable linear regression and logistic regression. Results: The rates of suicidal ideation and suicide attempts were the highest for chronic migraine with aura (ideation: 47.2%; attempts: 13.9%) and lowest in migraine-free controls (2.8%). Migraine frequency was an independent risk factor for suicidal ideation and attempts in patients with aura (both P trend < 0.001), but not in patients without auras. Migraine aura and depression were associated with higher risks of suicidal ideation and suicide attempts in patients with migraine. Conclusion: High migraine frequency has a correlation with high suicide risk in patients who experience an aura, but not in other patients with migraine.

Project description:ObjectiveTo compare the effectiveness and side effects of migraine prophylactic medications.DesignWe performed a network meta-analysis. Data were extracted independently in duplicate and quality was assessed using both the JADAD and Cochrane Risk of Bias instruments. Data were pooled and network meta-analysis performed using random effects models.Data sourcesPUBMED, EMBASE, Cochrane Trial Registry, bibliography of retrieved articles through 18 May 2014.Eligibility criteria for selecting studiesWe included randomized controlled trials of adults with migraine headaches of at least 4 weeks in duration.ResultsPlacebo controlled trials included alpha blockers (n = 9), angiotensin converting enzyme inhibitors (n = 3), angiotensin receptor blockers (n = 3), anticonvulsants (n = 32), beta-blockers (n = 39), calcium channel blockers (n = 12), flunarizine (n = 7), serotonin reuptake inhibitors (n = 6), serotonin norepinephrine reuptake inhibitors (n = 1) serotonin agonists (n = 9) and tricyclic antidepressants (n = 11). In addition there were 53 trials comparing different drugs. Drugs with at least 3 trials that were more effective than placebo for episodic migraines included amitriptyline (SMD: -1.2, 95% CI: -1.7 to -0.82), -flunarizine (-1.1 headaches/month (ha/month), 95% CI: -1.6 to -0.67), fluoxetine (SMD: -0.57, 95% CI: -0.97 to -0.17), metoprolol (-0.94 ha/month, 95% CI: -1.4 to -0.46), pizotifen (-0.43 ha/month, 95% CI: -0.6 to -0.21), propranolol (-1.3 ha/month, 95% CI: -2.0 to -0.62), topiramate (-1.1 ha/month, 95% CI: -1.9 to -0.73) and valproate (-1.5 ha/month, 95% CI: -2.1 to -0.8). Several effective drugs with less than 3 trials included: 3 ace inhibitors (enalapril, lisinopril, captopril), two angiotensin receptor blockers (candesartan, telmisartan), two anticonvulsants (lamotrigine, levetiracetam), and several beta-blockers (atenolol, bisoprolol, timolol). Network meta-analysis found amitriptyline to be better than several other medications including candesartan, fluoxetine, propranolol, topiramate and valproate and no different than atenolol, flunarizine, clomipramine or metoprolol.ConclusionSeveral drugs good evidence supporting efficacy. There is weak evidence supporting amitriptyline's superiority over some drugs. Selection of prophylactic medication should be tailored according to patient preferences, characteristics and side effect profiles.
