RESUMO
OBJECTIVE: To investigate whether medication-overuse headache patients have differential DNA-methylation pattern. METHODS: We collected blood samples from 120 medication-overuse headache-patients, 57 controls (29 episodic migraine patients and 28 healthy controls) in a hypothesis-generating cross-sectional case-control pilot study; 100 of the medication-overuse headache-patients were followed for six months and samples were collected at two and six months for the longitudinal methylation analyses. Blood cell proportions of leucocytes (neutrophils, NK-cells, monocytes, CD8+ and CD4+ T-cells, and B-cells) and the neutrophile-lymphocyte ratio were estimated using methylation data as a measure for immunological analysis and a cell type-specific epigenome wide association study was conducted between medication-overuse headache-patients and controls, and longitudinally for reduction in headache days/month among medication-overuse headache-patients. RESULTS: We found a higher neutrophile-lymphocyte ratio in medication-overuse headache-patients compared to controls, indicating a higher immunological response in medication-overuse headache-patients (false discovery rate (adjusted p-value)<0.001). Reduction in headache days/month (9.8; 95% CI 8.1-11.5) was associated with lower neutrophile-lymphocyte ratio (false discovery rate adjusted p-value = 0.041).Three genes (CORIN, CCKBR and CLDN9) were hypermethylated in specific cell types in medication-overuse headache-patients compared to controls. No methylation differences were associated with reduction in headache days in medication-overuse headache-patients after six months. CONCLUSION: This pilot study was consistent with higher immunological response in medication-overuse headache-patients which decreased with a reduction in headache days in longitudinal analysis. medication-overuse headache-patients exhibited differential methylation in innate immune cells but did not exhibit longitudinal differences with alterations in headache days. Our study creates hypotheses for further biomarker searches.ClinicalTrials.gov Identifier: NCT02993289.

BACKGROUND AND PURPOSE: There is a need to improve the diagnostic process of patients suspected of papilledema. In patients with known or suspected idiopathic intracranial hypertension a fundus imaging and perimetric visual field assessment system (COMPASS) performed at a headache center was validated in comparison to an assessment (Topcon plus OCTOPUS) at a neuroophthalmological clinic. METHODS: For intermethod assessment, blinded fundus images and perimetry from COMPASS versus Topcon plus OCTOPUS were assessed by a neuroophthalmologist. For interrater assessment, fundus images and perimetry obtained by the COMPASS system were assessed by an untrained medical doctor, a trained neurologist and a trained medical student and compared to the neuroophthalmologist's assessments. RESULTS: For the intermethod variation of the presence of papilledema on fundus images, a kappa value of 0.60, sensitivity of 87% and specificity of 73% were found. The interrater variation of the presence of papilledema on fundus images showed kappa values ranging from 0.43 to 0.74, sensitivity values ranging from 70% to 96% and specificity values ranging from 46% to 93% when comparing the assessments made by the headache center staff with neuroophthalmologist's assessments. The COMPASS showed a 59% sensitivity and moderate agreement in detecting visual field defects compared with OCTOPUS. The visual field assessment showed only slight to fair agreement from 0.19 to 0.31 between assessments made by the headache center staff and the neuroophthalmologist. CONCLUSION: The COMPASS system can be used with reasonable sensitivity in the assessment of papilledema in patients suspected of idiopathic intracranial hypertension at a tertiary headache center.

OBJECTIVES: To investigate previous treatment and clinical characteristics in migraine and tension-type headache patients at their first visit to a tertiary headache center. METHODS: This was a cross-sectional study using data obtained from electronic questionnaires and medical charts. Migraine and tension-type headache patients were investigated at their first visit to the Danish Headache Center. RESULTS: Out of 382 patients the main diagnoses of primary headaches were: 36% with episodic migraine, 43% with chronic migraine, 3% with episodic tension-type headache and 17% with chronic tension-type headache. The majority had attempted non-pharmacological treatment options such as physiotherapy (episodic migraine: 53%, chronic migraine: 68%, episodic tension-type headache: 50%, chronic tension-type headache: 65%) and acupuncture: (episodic migraine: 45%, chronic migraine: 62%, episodic tension-type headache: 17%, chronic tension-type headache: 51%). The majority of migraine patients had tried no more than one triptan (episodic migraine: 71%, chronic migraine: 66%). In total, 35% of episodic migraine and 19% of chronic migraine patients as well as 50% of episodic tension-type headache and 41% of chronic tension-type headache patients had never tried preventive medication. The headache under-response to treatment (HURT) questionnaire score was higher in chronic migraine (score 15) and chronic tension-type headache (score 16) patients than the episodic forms (P < 0.004). CONCLUSIONS: Headache patients had attempted several non-pharmacological treatments prior to their first visit at a tertiary headache center in Denmark. The limited use of acute and preventive treatment before the first visit demonstrates a need for better treatment at the primary and secondary care level.

OBJECTIVE: We investigated whether telephone follow-up consultations could lead to appropriate adjustment of treatments and a higher degree of patient satisfaction among patients with migraine and tension-type headache (TTH). BACKGROUND: Migraine and TTH are disabling headache forms requiring optimized treatment. METHODS: In a prospective, non-randomized, quality control study with controls comparing telephone-interview intervention (TeII) with business-as-usual (BAU) treatment, we included newly referred patients with migraine and/or TTH. The TeII group was contacted by telephone by healthcare professionals at 8 and 16 weeks after the first visit addressing headache treatment. Electronic questionnaires were sent to all participants before the first visit and after 6 months. Predefined outcomes were number of patients with change in preventive and acute medication; change in headache frequency; migraine frequency; scores from the eight-item Headache Under-Response to Treatment (HURT-8) questionnaire, Insomnia Severity Index (ISI), and Hospital Anxiety and Depression Scale (HADS); and patient satisfaction after 6 months. RESULTS: From May 2020 to April 2021, there were 230 patients enrolled in the TeII program, whereof 96 patients were included in the analysis. For the BAU group, 91 patients with similar sex and age distribution were identified via medical-record reviews in the same period. More patients in the TeII group than in the BAU group had a change in acute medication (27/96 [28%] vs. five of 91 [6%], p < 0.001) and preventive medication (28/96 [29%] vs. 12/91 [13%], p = 0.006). Headache days per month decreased in the TeII group (-4.6, 95% confidence interval [CI] -6.5 to -2.7; p = 0.001) and the BAU group (-2.5, 95% CI -4.6 to -0.4; p = 0.018), without significant difference between the groups (p = 0.080). There was no difference in migraine frequency between the groups (TeII: 1.0 day, 95% CI, -1.3 to 1.0; BAU: 1.0 day, 95% CI, -2.5 to 0.5; p = 0.718) or HURT-8 score (TeII: 10.5, 95% CI 9.5-11.5; BAU: 13.0, 95% CI 11.7-14.2; p = 0.053). There were no changes in the ISI score (TeII: 1.0, interquartile range [IQR] 6; p = 0.152; BAU: 0.5, IQR 4.5; p = 0.824), HADS-Anxiety score (TeII: -5, IQR 5.3; p = 0.186; BAU: 1.0, IQR 4.0; p = 0.445), or HADS-Depression score (TeII: 0.0, IQR 3.0; p = 0.163; BAU: 0.0, IQR 2.0; p = 0.303) in any of the groups. There was a higher degree of patient satisfaction in the TeII group compared with the BAU group in treatment (median [IQR] score 4 [3-5] vs. 3 [3-4], p < 0.001), headache improvement (median [IQR] 3 [2-4] vs. 2 [1-3], p = 0.002), the headache program (median [IQR] 4 [3-5] vs. 3 [3-4], p < 0.001), and information (median [IQR] 4 [3-5] vs. 3 [3-4], p = 0.005). CONCLUSION: Patients with migraine and/or TTH benefit from a telephone follow-up approach within the first 6 months of their treatment course in terms of more efficient treatment and higher patient satisfaction.

BACKGROUND: Headache disorders are globally prevalent and insufficient treatment contribute to low quality of life, increased disability, and socioeconomic costs. However, headache can to a large extent be treated appropriately by general practitioners. OBJECTIVE: To explore general practitioners' (GPs') management of patients with headache lasting ≥6 months. METHODS: In this retrospective descriptive cross-sectional study based on medical audit, all GPs practicing in Vejle municipality (population 116,992), Denmark, were invited to review their latest 20 patients with headache. Outcome measures were headache diagnostics, treatment, and referrals. Factors associated with referral to neurological treatment were examined by logistic regression. RESULTS: Of 26 invited practices, 19 participated reporting on 367 patients with lasting headache (71.4% women; mean-age 48.5 years). One hundred and sixty-one patients had migraine (44%; IQR: 28-60%), 140 (38%; IQR: 25-44%) had tension-type headache; 243 (66%; IQR: 50-79%) used simple analgesics, 147 (40%; IQR: 29-59%) triptans, 37 (10%; IQR: 0-14%) opioids, 93 (25%; IQR: 20-35%) were prescribed preventive medication; 176 (48%; IQR: 48-59%) were referred to neurologist, and 92 (25%; IQR: 10-37%) were referred to CT or MRI scan. Associated factors for referral were >1 headache diagnosis (aOR 1.75 [95% CI: 1.05-2.95]; P = 0.03), post-traumatic headache (aOR 2.53 [95% CI: 1.25-5.38]; P = 0.01), unspecific headache (aOR 2.04 [95% CI: 1.08-3.93]; P = 0.03), and using preventive treatment (aOR 2.75 [95% CI: 1.68-4.57]; P < 0.001). CONCLUSION: This study provides insights to how GPs manage patients with long-lasting headache. Focus should be on reducing opioids, increasing preventive treatment, and keeping more patients in primary care.
RESUMO
BACKGROUND: Tension-type headache (TTH) has been ranked the second most prevalent health condition worldwide. Non-pharmacological treatments for TTH are widely used as a supplement or an alternative to medical treatment. However, the evidence for their effects are limited. Therefore, the aim of this study was to review the evidence for manual joint mobilisation techniques, supervised physical activity, psychological treatment, acupuncture and patient education as treatments for TTH on the effect of headache frequency and quality of life. METHODS: A systematic literature search was conducted from February to July 2020 for clinical guidelines, systematic reviews, and individual randomised controlled trials (RCT). The primary outcomes measured were days with headache and quality of life at the end of treatment along with a number of secondary outcomes. Meta-analyses were performed on eligible RCTs and pooled estimates of effects were calculated using the random-effect model. The overall certainty of evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation approach (GRADE). In addition, patient preferences were included in the evaluation. RESULTS: In all, 13 RCTs were included. Acupuncture might have positive effects on both primary outcomes. Supervised physical activity might have a positive effect on pain intensity at the end of treatment and headache frequency at follow-up. Manual joint mobilisation techniques might have a positive effect on headache frequency and quality of life at follow-up. Psychological treatment might have a positive effect on stress symptoms at the end of treatment. No relevant RCTs were identified for patient education. The overall certainty of evidence was downgraded to low and very low. No serious adverse events were reported. A consensus recommendation was made for patient education and weak recommendations for the other interventions. CONCLUSION: Based on identified benefits, certainty of evidence, and patient preferences, manual joint mobilisation techniques, supervised physical activity, psychological treatment, acupuncture, and patient education can be considered as non-pharmacological treatment approaches for TTH. Some positive effects were shown on headache frequency, quality of life, pain intensity and stress symptoms. Few studies and low sample sizes posed a challenge in drawing solid conclusions. Therefore, high-quality RCTs are warranted.

BACKGROUND: Medication-overuse headache leads to high disability and decreased quality of life, and the best approach for withdrawal has been debated. AIM: To compare change in disability and quality of life between two withdrawal programs. METHODS: We randomized medication-overuse headache patients to program A (two months without acute analgesics or migraine medications) or program B (two months with acute medications restricted to two days/week) in a prospective, outpatient study. At 6 and 12 months, we measured disability and headache burden by the Headache Under-Response to Treatment index (HURT). We estimated quality of life by EUROHIS-QOL 8-item at 2-, 6-, and 12-month follow-up. Primary endpoint was disability change at 12 months. RESULTS: We included 72 medication-overuse headache patients with primary migraine and/or tension-type headache. Fifty nine completed withdrawal and 54 completed 12-month follow-up. At 12-month follow-up, 41 patients completed HURT and 38 completed EUROHIS-QOL 8-item. Disability reduction was 25% in program-A and 7% in program-B ( p = 0.027). Headache-burden reduction was 33% in program-A and 3% in program-B ( p = 0.005). Quality of life was increased by 8% in both programs without significant difference between the programs ( p = 0.30). At 2-month follow-up, quality of life increased significantly more in program-A than program-B ( p = 0.006). CONCLUSION: Both withdrawal programs reduced disability and increased quality of life. Withdrawal without acute medication was the most effective in reducing disability in medication-overuse headache patients. TRIAL REGISTRATION: Clinicaltrials.gov (NCT02903329).

BACKGROUND: Medication-overuse headache is a costly disease for individuals and society. OBJECTIVE: To estimate the impact of medication-overuse headache treatment on direct and indirect headache-related health care costs. METHODS: This prospective longitudinal study was part of the COMOESTAS project (COntinuous MOnitoring of Medication Overuse Headache in Europe and Latin America: development and STAndardization of an Alert and decision support System). Patients with medication-overuse headache were included from four European and two Latin American headache centers. Costs of acute medication, costs of health care services, and measurements of productivity were calculated at baseline and at 6-month follow-up Treatment consisted of overused drug withdrawal with optional preventive medication. RESULTS: A total of 475 patients (71%) completed treatment and were followed up for 6 months. Direct health care costs were on average reduced significantly by 52% ( p < 0.001) for the total study population. Significant reductions were seen in both number of consumed tablets (-71%, p < 0.001) and number of visits to physicians (-43%, p < 0.001). Fifty percent of patients reduced their number of consumed tablets ≥ 80%. Headache-related productivity loss, calculated either as absence from work or ≥ 50% reduction of productivity during the workday, were reduced by 21% and 34%, respectively ( p < 0.001). CONCLUSION: Standardized treatment of medication-overuse headache in six countries significantly reduced direct health care costs and increased productivity. This emphasizes the importance of increasing awareness of the value of treating medication-overuse headache. TRIAL REGISTRATION: The trial was registered at ClinicalTrials.gov (no. NCT02435056).

Background There is lack of evidence on how to detoxify medication-overuse headache. Aim To compare the effect of complete stop of acute medication with restricted intake. Methods Medication-overuse headache patients were included in a prospective, outpatient study and randomized to two months' detoxification with either a) no analgesics or acute migraine-medication (program A), or b) acute medication restricted to two days/week (program B). Detoxification was followed by preventives if indicated. Patients were followed up at 2, 6 and 12 months. Percentage reduction in headache days/month after 6 months was the primary outcome. Results We included 72 medication-overuse headache patients with a primary migraine and/or tension-type headache diagnosis. Fifty-nine completed detoxification, 58 (81%) were followed up at month 6 and 53 (74%) at month 12. At month 6, program A reduced headache days/month by 46% (95% CI 34-58) compared with 22% (95% CI 11-34) in program-B ( p = 0.005), and 70% in program A versus 42% in program B were reverted to episodic headache ( p = 0.04). Migraine-days/month were reduced by 7.2 in program A ( p < 0.001) and 3.6 in program B ( p = 0.002) after 6 months. Conclusion Both detoxification programs were very effective. Detoxification without analgesics or acute migraine-medication was the most effective program. Trial registration Clinicaltrials.gov (NCT02903329).

Background Medication-overuse headache is prevalent, but in principle preventable. Objective To describe the Danish national awareness campaign for medication-overuse headache. Methods The Danish Headache Center, the Association of Danish Pharmacies, and headache patient organizations implemented a four-month medication-overuse headache awareness campaign in 2016. Target groups were the general public, general practitioners, and pharmacists. Key messages were: Overuse of pain-medication can worsen headaches; pain-medication should be used rationally; and medication-overuse headache is treatable. A range of communication technologies was used. A survey on the public's awareness of medication-overuse headache was conducted. Results The Danish adult population is 4.2 million. Online videos were viewed 297,000 times in three weeks. All 400 pharmacies received campaign materials. Over 28,000 leaflets were distributed. Two radio interviews were conducted. A television broadcast about headache reached an audience of 520,000. Forty articles were published in print media. Information was accessible at 32 reputable websites and five online news agencies. Three scientific papers were published. Information was available at an annual conference of general practitioners, including a headache lecture. The survey showed an increase in percentage of the public who knew about medication-overuse headache (from 31% to 38%). Conclusion A concerted campaign to prevent medication-overuse headache can be implemented through involvement of key stakeholders.

BACKGROUND: Treatment with OnabotulinumtoxinA (BoNT-A) is effective as a preventive treatment for chronic migraine (CM). Preclinical studies suggest that the mechanism of action of BoNT-A in migraine is based on blocking unmyelinated C fibers. We aimed to investigate whether the muscle-relaxing effect of BoNT-A is associated with the preventive mechanism in patients with chronic migraine by measuring the stiffness, pain thresholds, and tenderness of the BoNT-A-applied muscles. METHODS: A total of 22 patients with CM who were already in BoNT-A treatment participated in this longitudinal prospective study. Pericranial muscle stiffness was measured using ultrasound shear wave elastography, which measures the speed of shear waves propagating through the muscle. Pressure pain thresholds (PPT) were obtained via algometry, and muscle tenderness was measured via manual palpation. Measurements were made before BoNT-A injections and six weeks after the treatment. The measurements were performed while the muscles were maximally relaxed. The patients also completed daily diaries on headache and neck pain. RESULTS: No change was observed in muscle stiffness (p = 0.737) or pericranial muscle tenderness (p = 0.400). The PPT over the trapezius muscles increased from 250 kPa before treatment to 304 kPa six weeks after treatment (p = 0.027). No change was observed on the temporalis muscles (p = 0.200) nor the non-dominant index finger (p = 0.067). BoNT-A decreased neck pain (p = 0.008) and headache (p = 0.007). CONCLUSIONS: The findings suggest that BoNT-A leads to the desensitization of cutaneous and muscle nociceptors in the head and neck regions, whereas muscle relaxation might not be an important part of the anti-migraine effect.
RESUMO
BACKGROUND: Headache calendars are essential tools in monitoring changes in headache frequency and type. They are used in clinical practice for long-term monitoring, but their validation remains limited. The aim of this study was to validate the use of a digital calendar in monitoring single migraine and tension-type headache attacks. METHODS: From July 2022 to February 2023, patients diagnosed with migraine and tension-type headache were enrolled. The validation of the digital calendar involved the comparison of self-reported single headache attacks in the digital calendar with the diagnostic headache diary based on the ICHD-3 criteria for migraine and tension-type headache. Sensitivity and specificity were calculated to assess reliability, and the level of agreement was calculated using kappa statistics. RESULTS: This study included 30 patients (87% women) diagnosed with migraine and tension-type headache. The level of agreement in the classification of a single migraine attack revealed a sensitivity of 82% and a specificity of 78%, representing a substantial level of agreement (κ = 0.60). The classification of a single tension-type headache attack revealed a sensitivity of 84% and a specificity of 72%, with a moderate level of agreement (κ = 0.54). CONCLUSIONS: The digital calendar proves effective in monitoring single headache attacks in patients with migraine and tension-type headache. In clinical practice, we recommend using the digital calendar as a monitoring tool for headache patients, as they can accurately identify true migraine and tension-type headache days.
RESUMO
Importance: Medication overuse headache (MOH) is a disabling, globally prevalent disorder representing a well-known and debated clinical problem. Evidence for the most effective treatment strategy is needed. Objective: To compare 3 treatment strategies for MOH. Design, Setting, and Participants: This open-label, randomized clinical trial with 6 months of follow-up was conducted in the tertiary sector at the Danish Headache Center, Glostrup, from October 25, 2016, to June 28, 2019. Of 483 patients with MOH referred during the inclusion period, 195 met the criteria consisting of migraine and/or tension-type headache, 18 years or older, eligibility for outpatient treatment, no severe physical or psychiatric disorder, no other addiction, and not pregnant or breastfeeding. Of these, 75 refused participation and 120 were included. Data were analyzed from July 3 to September 6, 2019. Interventions: Random assignment (1:1:1 allocation) to 1 of the 3 outpatient treatments consisting of (1) withdrawal plus preventive treatment, (2) preventive treatment without withdrawal, or (3) withdrawal with optional preventive treatment 2 months after withdrawal. Main Outcomes and Measures: The primary outcome was change in headache days per month after 6 months. Predefined secondary outcomes were change in monthly migraine days, use of short-term medication, pain intensity, number of responders, patients with remission to episodic headache, and cured MOH. Results: Of 120 patients, 102 (mean [SD] age, 43.9 [11.8] years; 81 women [79.4%]) completed the 6-month follow-up. Headache days per month were reduced by 12.3 (95% CI, 9.3-15.3) in the withdrawal plus preventive group, by 9.9 (95% CI, 7.2-12.6) in the preventive group, and by 8.5 (95% CI, 5.6-11.5) in the withdrawal group (P = .20). No difference was found in reduction of migraine days per month, use of short-term medication, or headache intensity. In the withdrawal plus preventive group, 23 of 31 patients (74.2%) reverted to episodic headache, compared with 21 of 35 (60.0%) in the preventive group and 15 of 36 (41.7%) in the withdrawal group (P = .03). Moreover, 30 of 31 patients (96.8%) in the withdrawal plus preventive group were cured of MOH, compared with 26 of 35 (74.3%) in the preventive group and 32 of 36 (88.9%) in the withdrawal group (P = .03). These findings corresponded to a 30% (relative risk, 1.3; 95% CI, 1.1-1.6) increased chance of MOH cure in the withdrawal plus preventive group compared with the preventive group (P = .03). Conclusion and Relevance: All 3 treatment strategies were effective, but based on these findings, withdrawal therapy combined with preventive medication from the start of withdrawal is recommended as treatment for MOH. Trial Registration: ClinicalTrials.gov Identifier: NCT02993289.

BACKGROUND: Complete stop of acute medication and/or migraine medication for treatment of medication-overuse headache (MOH) has previously been reported more effective in reducing headache days and migraine days per month compared with restricted intake of acute medication. However, it is unknown whether complete stop or restricted intake is the most feasible treatment for patients. OBJECTIVES: To investigate whether feasibility of withdrawal in MOH is different between complete stop of acute medication and restricted intake, and whether reductions in headache-related medication dependence, anxiety and depression differ between the treatments. METHODS: Medication-overuse headache patients were included in a prospective, open-label, outpatient study and randomized to two months of withdrawal with either no analgesics or acute migraine medication (programme A) or acute medication restricted to 2 days/week (programme B). After 6 and 12 months, patients graded feasibility of withdrawal. Dependence was measured by Severity of Dependence Scale (SDS), while anxiety and depression were measured by Hospital Anxiety and Depression Scale (HADS). RESULTS: We included 72 MOH patients with primary migraine and/or tension-type headache. Forty-nine completed withdrawal and the SDS questionnaire at 12-month follow-up, and the feasibility of withdrawal was significantly higher in programme A compared to programme B (p < 0.001). At 12 months, the dependence was reduced by 44% in programme A compared to 26% in programme B (p = 0.053), while the anxiety score was reduced by 32% and 11%, respectively (p = 0.048). CONCLUSIONS: Withdrawal with complete stop of acute medication was more feasible and most effective in reducing headache-related anxiety compared with restricted intake. SIGNIFICANCE: A complete stop of all analgesics is the most effective treatment for MOH regarding reduction in headache days but has often been regarded as too challenging for patients. However, in this study, complete stop appears to be more feasible compared with restricted intake of analgesics seen from the patients' perspective.

Medication-overuse headache (MOH) is a disabling, costly and often overlooked disorder. The prevalence in Denmark is 1.8% equivalent to 80.000-100.000 adults. The aim is to increase awareness of clinical presentation and treatment options for patients with MOH when encountered in primary care setting, exemplified by three representative cases. Clinical presentation of MOH and three treatment approaches are discussed. MOH is a chronic disorder which is preventable and treatable.
