Key clinical point: Rimegepant orally disintegrating tablet (ODT) offers pain relief within 2 hours of treatment in adults with migraine, with a tolerable safety profile.

Major finding: At 2 hours post dose, rimegepant was more effective than placebo in providing freedom from pain (risk difference 7.6; P = .0004) and the most bothersome symptom (risk difference 16.2; P < .0001). The overall rates of treatment-emergent adverse events were comparable between the rimegepant and placebo groups (15.2% and 16.4%, respectively).

Study details: This subgroup analysis of a double-blind, randomized, placebo-controlled phase 3 clinical trial included 1075 patients with acute migraine with or without aura (age ≥ 18 years) who were randomly assigned to receive either 75 mg rimegepant ODT (n = 538) or placebo (n = 537).

Disclosures: This study was funded by BioShin, a wholly owned subsidiary of Biohaven Pharmaceuticals, which was acquired by Pfizer. Pfizer provided writing support. Five authors declared being employees or stock owners of Biohaven, BioShin, or Pfizer. The remaining authors declared no conflicts of interest.

Key clinical point: Combination therapy with two parenteral agents or monotherapy with either neuroleptics or metoclopramide can be considered as a first-line treatment option for the management of acute migraine pain in the emergency department (ED) settings.

Major finding: Combination therapy of two parenteral agents vs placebo was an effective treatment option in reducing pain intensity scores (mean difference −3.36; 95% CI −4.64 to −2.08) and increasing the rate of achievement of pain relief (risk ratio 2.83; 95% CI 1.74-4.61). Monotherapy with neuroleptics and metoclopramide also provided pain relief and helped patients achieve pain-free status prior to discharge from the ED but increased the risk for adverse events, especially akathisia.

Study details: This meta-analysis of 97 randomized controlled trials evaluated the effectiveness of various parenteral agents for pain relief in patients with acute migraine presenting to the ED.

Key clinical point: In patients with migraine, greater severity of photophobia is significantly associated with worse sleep-related outcomes, such as sleep quality (SQ), sleep disturbance (SDi), sleep onset latency (SOL), sleep-related impairment (SRI), and insomnia.

Major finding: Compared with patients with migraine and without photophobia, those with migraine and photophobia presented significantly poorer SQ (β 0.15; P < .001), longer SOL (β 0.10; P = .011), higher levels of SDi (β 0.12; P < .001) and SRI (β 0.08; P = .020), and a higher prevalence of insomnia (β 0.11; P = .005).

Outcomes of Acute and Preventive Migraine Therapy Based on Patient Sex

I previously have addressed myths about migraine as they pertain to men and women. When I found an interesting study recently published in Cephalalgia investigating the effectiveness of calcitonin gene-related peptide receptor (CGRP-R) antagonists (gepants) for acute care and prevention of episodic migraine and CGRP monoclonal antibodies for preventive treatment of episodic and chronic migraine in men and women, I thought I would discuss it here.

The study’s aim was to discern if patient sex contributed to outcomes in each specific treatment arm. Female sex hormones have been recognized as factors in promoting migraine, and women show increased severity, persistence, and comorbidity in migraine profiles, and increased prevalence of migraine relative to men.

Gepants used for acute therapy (ubrogepant, rimegepant, zavegepant) and preventive therapy (atogepant, rimegepant) were studied in this trial. Erenumab, fremanezumab, galcanezumab, and eptinezumab are monoclonal antibodies that either sit on the CGRP receptor (erenumab) or inactivate the CGRP ligand (fremanezumab, galcanezumab, and eptinezumab) and are used for migraine prevention. CGRP-based therapies are not effective in all patients and understanding which patient groups respond preferentially could reduce trial and error in treatment selection. The effectiveness of treatments targeting CGRP or the CGRP receptor may not be uniform in men and women, highlighting the need for further research and understanding of CGRP neurobiology in both sexes.

Key findings:

• In the trial by Porreca et al: In women, the 3 gepants approved by the FDA for the acute care of migraine (ubrogepant, rimegepant, zavegepant) produced a statistically significant drug effect for the 2-hour pain freedom (2h-PF) endpoint, with an average drug effect of 9.5% (CI: 7.4 to 11.6) and an average number needed to treat (NNT) of 11.
• Men did not show statistically significant effects with the acute use of gepants. The average drug effect was 2.8%, and the average NNT was 36.
• For both men and women, CGRP-targeting therapies for prevention of migraine (the 4 monoclonal antibodies) were equally effective; however, possible sex differences remain uncertain and need further study.
• In patients with chronic migraine, CGRP/CGRP-R antibodies were similarly effective in both men and women.
• For the 2-hour freedom from most bothersome symptom (2h-MBS) endpoint when gepants were given acutely, the effects were much better in women than men, with an average drug effect of 10.2% and an average NNT of 10.
• In men, these medications produced observed treatment effects on 2h-MBS with an average drug effect of 3.2% and an average NNT of 32.
• In men, 5 out of 12 estimates favored placebo over the active treatment, suggesting a treatment with little to no effect.
• The pooled treatment effects for women were 3 times as large, at 9.2% and 10.2%, respectively.
• The placebo response rates for 2 of the 3 ubrogepant studies and one of 2 zavegepant studies were higher in men than in women.

The study concludes that, while small molecule CGRP-R antagonists are dramatically effective for acute therapy of migraine in women, available data do not demonstrate effectiveness in men. The treatment effect was found to always favor active treatment numerically for both men and women for prevention of episodic and chronic migraine. The data highlight possible differential effects of CGRP-targeted therapies in different patient populations and the need for increased understanding of CGRP neurobiology in men and women. The study also emphasizes the need to understand which patient groups preferentially respond to CGRP-based therapies to reduce trial and error in treatment. Note that rimegepant data on prevention were not available for analysis at the time of the writing.

It would be interesting to perform a meta-analysis of multiple well-done, large, real-world studies to see if the same differences and similarities are found in men versus women for acute care of migraine and prevention of episodic and chronic migraine. I suspect that we would find that acute care results favor women but that some men do well.

The Effectiveness of Prednisolone for Treating Medication Overuse Headache

I often discuss medication overuse headache (MOH), as it is difficult to diagnose and treat, so I wanted to comment on another pertinent study. It is a post hoc analysis of the Registry for Load and Management of Medication Overuse Headache (RELEASE). The RELEASE trial is an ongoing, multicenter, observational, cohort study of MOH that has been conducted in Korea since April 2020. Findings were recently published in Headache by Lee et al.

MOH is a secondary headache disorder that develops in patients with a preexisting primary headache when they overuse acute care headache medications of any type except gepants. This includes prescription medications such as triptans, ergots, butalbital-containing medications; opioids; aspirin; acetaminophen; any type of combination medication often containing caffeine; or a combination of medications. This condition significantly impacts patients’ quality of life and productivity, usually increasing the frequency of headaches per month and leading to higher healthcare-related costs.

Treating MOH is challenging due to the lack of high-quality drug trials specifically designed for MOH and doctor inexperience. Current evidence is based largely on subgroup analyses of drug trials for the treatment of chronic migraine that contain these patient types.

Withdrawal of acute care headache medications that are being overused has traditionally been considered an important aspect of MOH treatment, although this may be changing. Withdrawal symptoms, such as increased intensity of headache pain, frequency of headaches, and other symptoms like agitation and sleep disturbance, can prevent patients from discontinuing overused medications. Systemic corticosteroids are widely used to reduce these withdrawal headaches, but clinical trials are sparse and have failed to meet proper endpoints. Despite this, corticosteroids have shown potential benefits, such as decreasing withdrawal headaches, reducing the use of rescue medications, and lowering headache intensity at certain time points after treatment.

Given these findings, this published study hypothesized that prednisolone may play a role in converting MOH to non-MOH at 3 months after treatment. The objective was to evaluate the outcome of prednisolone therapy in reversing medication overuse at 3 months posttreatment in patients with MOH using prospective multicenter registry data. Prednisolone was prescribed to 59 out of 309 patients (19.1%) enrolled during this observational study period, with doses ranging from 10 to 40 mg/day for 5-14 days. Of these patients, 228 (73.8%) completed the 3-month follow-up period.

Key findings:

• The MOH reversal rates at 3 months postbaseline were 76% (31/41) in the prednisolone group and 57.8% (108/187) in the no prednisolone group (p = 0.034).
• The steroid effect remained significant (adjusted odds ratio, 2.78; 95% confidence interval 1.27-6.1, p = 0.010) after adjusting for the number of monthly headache days at baseline, mode of discontinuation of overused medication, use of early preventive medications, and the number of combined preventive medications.

The study had several strengths, including the multicenter collection of data, prospective follow-ups, and comprehensiveness of data acquisition. However, it also had significant limitations, such as the noninterventional, observational nature of the study, potential bias in steroid prescription (every doctor prescribed what they wanted), and heterogeneity in the patient population. Also, there were a variety of treatments, and they were not standardized. Further external validation may be necessary before generalizing the study results.

Despite these limitations, the results do suggest that prednisolone may be one part of a valid treatment option for patients with MOH. I suspect, if the proper studies are done, we will see that using a good preventive medication, with few adverse events, and with careful education of the patient, formal detoxification will not be necessary when treating many patients with MOH. This has been my experience with MOH treatment utilizing the newer anti-CGRP preventive medications, including the older monoclonal antibodies and the newer gepants.

The objective was to evaluate the outcome of prednisolone therapy in reversing medication overuse at 3 months posttreatment in patients with MOH using prospective multicenter registry data. Prednisolone was prescribed to 59 out of 309 patients (19.1%) enrolled during this observational study period, with doses ranging from 10 to 40 mg/day for 5-14 days. Of these patients, 228 (73.8%) completed the 3-month follow-up period.

Key findings:

• The MOH reversal rates at 3 months postbaseline were 76% (31/41) in the prednisolone group and 57.8% (108/187) in the no prednisolone group (p = 0.034).
• The steroid effect remained significant (adjusted odds ratio, 2.78; 95% confidence interval 1.27-6.1, p = 0.010) after adjusting for the number of monthly headache days at baseline, mode of discontinuation of overused medication, use of early preventive medications, and the number of combined preventive medications.

The study had several strengths, including the multicenter collection of data, prospective follow-ups, and comprehensiveness of data acquisition. However, it also had significant limitations, such as the noninterventional, observational nature of the study, potential bias in steroid prescription (every doctor prescribed what they wanted), and heterogeneity in the patient population. Also, there were a variety of treatments, and they were not standardized. Further external validation may be necessary before generalizing the study results.

Despite these limitations, the results do suggest that prednisolone may be one part of a valid treatment option for patients with MOH. I suspect, if the proper studies are done, we will see that using a good preventive medication, with few adverse events, and with careful education of the patient, formal detoxification will not be necessary when treating many patients with MOH. This has been my experience with MOH treatment utilizing the newer anti-CGRP preventive medications, including the older monoclonal antibodies and the newer gepants.

Outcomes of Acute and Preventive Migraine Therapy Based on Patient Sex

I previously have addressed myths about migraine as they pertain to men and women. When I found an interesting study recently published in Cephalalgia investigating the effectiveness of calcitonin gene-related peptide receptor (CGRP-R) antagonists (gepants) for acute care and prevention of episodic migraine and CGRP monoclonal antibodies for preventive treatment of episodic and chronic migraine in men and women, I thought I would discuss it here.

The study’s aim was to discern if patient sex contributed to outcomes in each specific treatment arm. Female sex hormones have been recognized as factors in promoting migraine, and women show increased severity, persistence, and comorbidity in migraine profiles, and increased prevalence of migraine relative to men.

Gepants used for acute therapy (ubrogepant, rimegepant, zavegepant) and preventive therapy (atogepant, rimegepant) were studied in this trial. Erenumab, fremanezumab, galcanezumab, and eptinezumab are monoclonal antibodies that either sit on the CGRP receptor (erenumab) or inactivate the CGRP ligand (fremanezumab, galcanezumab, and eptinezumab) and are used for migraine prevention. CGRP-based therapies are not effective in all patients and understanding which patient groups respond preferentially could reduce trial and error in treatment selection. The effectiveness of treatments targeting CGRP or the CGRP receptor may not be uniform in men and women, highlighting the need for further research and understanding of CGRP neurobiology in both sexes.

Key findings:

• In the trial by Porreca et al: In women, the 3 gepants approved by the FDA for the acute care of migraine (ubrogepant, rimegepant, zavegepant) produced a statistically significant drug effect for the 2-hour pain freedom (2h-PF) endpoint, with an average drug effect of 9.5% (CI: 7.4 to 11.6) and an average number needed to treat (NNT) of 11.
• Men did not show statistically significant effects with the acute use of gepants. The average drug effect was 2.8%, and the average NNT was 36.
• For both men and women, CGRP-targeting therapies for prevention of migraine (the 4 monoclonal antibodies) were equally effective; however, possible sex differences remain uncertain and need further study.
• In patients with chronic migraine, CGRP/CGRP-R antibodies were similarly effective in both men and women.
• For the 2-hour freedom from most bothersome symptom (2h-MBS) endpoint when gepants were given acutely, the effects were much better in women than men, with an average drug effect of 10.2% and an average NNT of 10.
• In men, these medications produced observed treatment effects on 2h-MBS with an average drug effect of 3.2% and an average NNT of 32.
• In men, 5 out of 12 estimates favored placebo over the active treatment, suggesting a treatment with little to no effect.
• The pooled treatment effects for women were 3 times as large, at 9.2% and 10.2%, respectively.
• The placebo response rates for 2 of the 3 ubrogepant studies and one of 2 zavegepant studies were higher in men than in women.

The study concludes that, while small molecule CGRP-R antagonists are dramatically effective for acute therapy of migraine in women, available data do not demonstrate effectiveness in men. The treatment effect was found to always favor active treatment numerically for both men and women for prevention of episodic and chronic migraine. The data highlight possible differential effects of CGRP-targeted therapies in different patient populations and the need for increased understanding of CGRP neurobiology in men and women. The study also emphasizes the need to understand which patient groups preferentially respond to CGRP-based therapies to reduce trial and error in treatment. Note that rimegepant data on prevention were not available for analysis at the time of the writing.

It would be interesting to perform a meta-analysis of multiple well-done, large, real-world studies to see if the same differences and similarities are found in men versus women for acute care of migraine and prevention of episodic and chronic migraine. I suspect that we would find that acute care results favor women but that some men do well.

The Effectiveness of Prednisolone for Treating Medication Overuse Headache

I often discuss medication overuse headache (MOH), as it is difficult to diagnose and treat, so I wanted to comment on another pertinent study. It is a post hoc analysis of the Registry for Load and Management of Medication Overuse Headache (RELEASE). The RELEASE trial is an ongoing, multicenter, observational, cohort study of MOH that has been conducted in Korea since April 2020. Findings were recently published in Headache by Lee et al.

MOH is a secondary headache disorder that develops in patients with a preexisting primary headache when they overuse acute care headache medications of any type except gepants. This includes prescription medications such as triptans, ergots, butalbital-containing medications; opioids; aspirin; acetaminophen; any type of combination medication often containing caffeine; or a combination of medications. This condition significantly impacts patients’ quality of life and productivity, usually increasing the frequency of headaches per month and leading to higher healthcare-related costs.

Treating MOH is challenging due to the lack of high-quality drug trials specifically designed for MOH and doctor inexperience. Current evidence is based largely on subgroup analyses of drug trials for the treatment of chronic migraine that contain these patient types.

Withdrawal of acute care headache medications that are being overused has traditionally been considered an important aspect of MOH treatment, although this may be changing. Withdrawal symptoms, such as increased intensity of headache pain, frequency of headaches, and other symptoms like agitation and sleep disturbance, can prevent patients from discontinuing overused medications. Systemic corticosteroids are widely used to reduce these withdrawal headaches, but clinical trials are sparse and have failed to meet proper endpoints. Despite this, corticosteroids have shown potential benefits, such as decreasing withdrawal headaches, reducing the use of rescue medications, and lowering headache intensity at certain time points after treatment.

Given these findings, this published study hypothesized that prednisolone may play a role in converting MOH to non-MOH at 3 months after treatment. The objective was to evaluate the outcome of prednisolone therapy in reversing medication overuse at 3 months posttreatment in patients with MOH using prospective multicenter registry data. Prednisolone was prescribed to 59 out of 309 patients (19.1%) enrolled during this observational study period, with doses ranging from 10 to 40 mg/day for 5-14 days. Of these patients, 228 (73.8%) completed the 3-month follow-up period.

Key findings:

• The MOH reversal rates at 3 months postbaseline were 76% (31/41) in the prednisolone group and 57.8% (108/187) in the no prednisolone group (p = 0.034).
• The steroid effect remained significant (adjusted odds ratio, 2.78; 95% confidence interval 1.27-6.1, p = 0.010) after adjusting for the number of monthly headache days at baseline, mode of discontinuation of overused medication, use of early preventive medications, and the number of combined preventive medications.

Proton pump inhibitors (PPIs), which are used to control acid reflux, are associated with an increased risk for migraine and other severe headache types, new research showed. 

Using data from the National Health and Nutrition Examination Survey (NHANES), investigators conducted a cross-sectional analysis and found all types of acid-suppression therapy were associated with an increased risk for severe headache including migraine but that PPIs conferred the greatest risk.

“It’s important to note that many people do need acid-reducing medications to manage acid reflux or other conditions, and people with migraine or severe headache who are taking these drugs or supplements should talk with their doctors about whether they should continue,” lead author Margaret Slavin, PhD, of the University of Maryland in College Park, said in a press release. 

The findings were published online  in Neurology Clinical Practice. 
 

New Look at Old Data

Previous research has shown that headache is listed among the most common adverse reactions in adults taking PPIs and histamine receptor agonists (H2RAs), which include cimetidine, famotidine, and nizatidine.

Other large studies of health databases have shown increased headache risk within a week of PPI exposure.

To compare the risk from PPIs versus H2RAs and other generics, researchers analyzed data from the NHANES for those who used PPIs, H2RAs, and generic antacids to learn more about the potential link between acid-suppression therapy and headache.

They used survey data from 1999 to 2004, the only years the NHANES included a question about migraine and other headache during the past 3 months. 

Investigators analyzed data for 11,800 participants aged 20 years or older who used prescription drugs, over-the-counter medications, and nutritional supplements during the past month. 

Participants who used acid-suppressing medications had an increased risk for migraine or severe headache versus those who did not use these agents. Investigators found PPIs were tied to a 70% increased risk, while H2RAs and antacids were associated with 40% and 30% higher risks, respectively. Use of any type of acid-suppression therapy was tied to a 47% increased risk for severe headache.
 

Magnesium a Risk Factor?

While magnesium supplements are sometimes prescribed as a “natural” headache prevention therapy to prevent migraine and other headache types, the investigators noted they were surprised to find individuals taking H2RAs who met the dietary reference intake for magnesium had a nearly threefold increased risk for migraine or severe headache (odds ratio, 2.80; 95% CI, 1.02-1.45; P = .025).

However, there was no association between magnesium and the other acid-reducing medications. 

The study’s limitations included the use of a single question to identify migraine or severe headache, which may have resulted in some misclassification of the outcome. The authors also pointed out that dietary and drug-intake data may be subject to recall bias. 

“These results suggest that there is a need for more intentionally designed prospective work to inform the extent to which associations between migraine and acid-suppression therapy are merely detecting comorbidities or to what extent migraine is an adverse event associated with the medications,” the authors wrote. 

There was no targeted funding. Disclosures are noted in the original article.

DENVER — Among patients with major depressive disorder, transcranial magnetic stimulation (TMS) had similar efficacy to electroconvulsive therapy (ECT), according to results from a retrospective study of patients treated in the past 20 years.

“We always learn in our textbooks that after about two or three medication trials is when you can start exploring more serious treatment protocols, such as ECT or TMS, but a lot of these patients weren’t going forward with it, and I was curious about it. I figured that TMS, which is a less expensive, less scary procedure that patients would more likely be open to, that is also approved for treatment resistant depression, would be a good alternative to ECT,” said Anuttham Kandhadai, a third-year medical student at University of Texas Medical Branch at Galveston, who presented the study at the 2024 annual meeting of the American Academy of Neurology.
 

Study Findings Lead to More Questions

The researchers found lower rates of depressive episodes, suicidal attempts, and suicidal ideation among patients treated with TMS, but an important limitation was that the researchers did not know the severity of the depression in the two patient groups, according to Branch Coslett, MD, who attended the session and has performed research with TMS to treat aphasia in stroke patients. “I think it’s a very interesting study, and certainly something worth pursuing, but given that ECT is only used as a last resort, whereas TMS is often used as a second-line therapy, I think you’re really talking about very different populations that have had these treatments,” said Dr. Coslett.

Mr. Kandhadai recognized the limitations of the study and looks forward to expanding the research. “I’d love to explore cost effectiveness of the treatments. I’d love to explore patient familiarity and patient comfort with different treatments. And I’d also love to explore a more controlled study that can determine how severe someone’s depression is, and then be able to control for that and explore the outcomes based on the treatment protocol,” he said.

The ideal comparative study would be prospective, “but that will never be done. One Flew Over the Cuckoo’s Nest and similar sources of information have really poisoned the well,” said Dr. Coslett. However, he noted that advances have been made in ECT, and that targeting the right hemisphere produces fewer side effects: “The outcomes from unilateral right hemisphere stimulation are said to be every bit as good or maybe better, and you don’t get the confusion, you don’t get the memory loss, you don’t get all that sort of stuff that you’d expect when somebody has a prolonged, generalized tonic-clonic seizure.”

Still, people are naturally reluctant to undergo ECT. “I’ve seen it. It’s pretty barbaric. It’s better now and at my institution, people do get it, but they really, really have to be intractable,” he said.
 

Comparing Treatment Options

Mr. Kandhadai and his co-authors used the TriNetX database to identify patients with treatment-resistant major depressive disorder who received TMS or ECT in the past 20 years. There were 2,916 patients in both cohorts, who were matched by age, sex, ethnicity, mood and behavioral disorders, endocrine disorders, intellectual disabilities, cerebrovascular disease, and other nervous system disorders. The mean age at treatment was 48.2 years, 38.5% were male, and 3.1% were Black or African American.

Short-term outcomes favored TMS, including the frequency of disorientation (0.41% vs 2.81%), retrograde amnesia (0.34% vs 0.65%), and headache (4.36% vs 7.20%). Long-term outcomes from 1 month to 5 years post treatment were also better in the TMS group, including depressive episodes (44.99% vs 53.77%), suicide attempts (3.98% vs 6.86%), and suicidal ideation (12.38% vs 23.49%). Kaplan-Meier curve analysis between 1 month and 5 years showed a benefit to TMS in probability of not experiencing a depressive episode, and not experiencing suicidal ideation.

“ECT has been the gold standard of treatment resistant depression for a long time, and it deserves to be. I think it’s something you should offer your patients. Not everyone might be comfortable with it, and if they’re not, I think it’s important to not stop the conversation there, but to offer something like TMS because TMS is something that might be more accessible to patients. It might be more affordable, and it might be less scary,” said Mr. Kandhadai

Migraine and other headache types are common ailments, and there are many stereotypes and stigmas associated with these conditions. One of the prevailing beliefs about headaches and migraines is that they are linked with internalizing mental health conditions — anxiety and depression. These associations can affect pediatric migraine patients and their parents in complicated ways, potentially hindering adequate diagnosis and treatment. Results of a recent prospective study, published in the journal Headache, provided results that challenge the widespread belief that people who have migraines have a higher-than-average rate of internalizing mental health disorders. The authors provided a discussion and data to explain that their initial hypothesis of a relationship between migraine and mental health was disproven. The study included 123 participants age 8-18 years who had been previously diagnosed with migraine. The patients, who were seen in a pediatric neurology clinic, completed headache questionnaires and validated measures of anxiety and depressive symptoms. The final analysis showed no significant association between migraines or headaches with anxiety or depression.

Why does this matter? Stigma can prevent patients and parents from seeking care if parents feel that they will be judged as bad parents for contributing to their children's anxiety, depression, headaches, and migraines. In fact, beyond mental health stigma, children who have migraine can be blamed for having an unhealthy lifestyle.^[1] While advice to get enough sleep, eat healthy, and stay active is worthwhile, there can be an implication that pediatric migraine patients are causing their migraines by living an unhealthy lifestyle.^[1] Additionally, the implication that parents are not properly taking care of their children's health can inhibit an accurate symptom history. Releasing pediatric migraine patients and their parents from myths about migraines and headaches can be a beneficial component of doctor-patient communication regarding migraine care.

It is possible that dietary adjustments or supplements could help improve migraine frequency and severity. Maintaining a healthy diet is a frequent recommendation for people who have headaches, but it can be frustrating for patients to receive general recommendations to follow a healthy lifestyle. Specific direction regarding which foods to avoid and which foods to add to a diet can be helpful for patients as they try to navigate the challenge of adopting migraine-friendly lifestyle changes.

Eicosapentaenoic acid (EPA) is one of the omega-3 fatty acids. A recent study, with results published in Brain, Behavior, and Immunity, examined the effects of EPA on migraines. The 12-week randomized, double-blind, placebo-controlled trial included 70 participants who had been diagnosed with episodic migraine. Participants were randomly assigned to either EPA (2 g fish oil with 1.8 g of EPA/day) or placebo (2 g soybean oil/day). Migraine frequency and severity were assessed using standardized scales. According to the authors, the high-dose-EPA group had significantly reduced migraine frequency and severity, fewer number of days using acute treatment, reduced migraine-associated disability, improved anxiety and depression, and improved quality of life in comparison to the placebo group. The EPA group did not experience notable adverse events.To provide a sense of scale regarding dietary EPA, 3 oz of cooked wild salmon has 0.35 g of EPA, 3 oz of cooked shrimp has 0.2 g of EPA, and 3 oz of light canned tuna has 0.02 g of EPA.^[2] Thus, it's important to note that the amount of EPA used in this study was higher than what would be expected of dietary EPA.

An observational prospective study published in Scientific Reports examined the effects of dietary phytochemical index (DPI) on migraine. DPI is defined as the proportion of daily energy intake derived from foods rich in phytochemicals. Consumption of phytochemical-rich foods has been associated with cardiovascular and metabolic diseases prevention in various populations. These foods include fruits, vegetables, whole grains, seeds, nuts, and legumes. The study included 265 adults age 20-50 who had a diagnosis of migraine. Participants were asked to fill out a questionnaire, which was used to evaluate their diet in the preceding year, and they were asked to complete a diary to track their migraine symptoms. The results showed an inverse relationship between DPI index and migraine frequency. Participants who had the highest DPI had the lowest migraine frequency.^[3] While the authors found the results to be statistically significant, they did not point to a cause and effect. Migraine-associated symptoms such as nausea can have an effect on dietary choices, so patients who experience migraine symptoms may avoid certain foods before, during, or after a migraine episode. They also may consistently avoid foods that they have experienced as migraine triggers.

Diet and lifestyle can have an effect on migraine frequency, severity, and overall migraine-associated quality of life. Beyond general recommendations, however, it is not yet well established which foods or supplements could potentially help alleviate migraines. Advice to maintain a healthy lifestyle is definitely worthwhile for migraine patients, but it is important to avoid conveying blame or stigma when it comes to communication about the effect of lifestyle on migraine. This is especially important for pediatric migraine patients because the stigma extends beyond children to parents and could potentially interfere with clear communication and adequate care.

Migraine and other headache types are common ailments, and there are many stereotypes and stigmas associated with these conditions. One of the prevailing beliefs about headaches and migraines is that they are linked with internalizing mental health conditions — anxiety and depression. These associations can affect pediatric migraine patients and their parents in complicated ways, potentially hindering adequate diagnosis and treatment. Results of a recent prospective study, published in the journal Headache, provided results that challenge the widespread belief that people who have migraines have a higher-than-average rate of internalizing mental health disorders. The authors provided a discussion and data to explain that their initial hypothesis of a relationship between migraine and mental health was disproven. The study included 123 participants age 8-18 years who had been previously diagnosed with migraine. The patients, who were seen in a pediatric neurology clinic, completed headache questionnaires and validated measures of anxiety and depressive symptoms. The final analysis showed no significant association between migraines or headaches with anxiety or depression.

Why does this matter? Stigma can prevent patients and parents from seeking care if parents feel that they will be judged as bad parents for contributing to their children's anxiety, depression, headaches, and migraines. In fact, beyond mental health stigma, children who have migraine can be blamed for having an unhealthy lifestyle.^[1] While advice to get enough sleep, eat healthy, and stay active is worthwhile, there can be an implication that pediatric migraine patients are causing their migraines by living an unhealthy lifestyle.^[1] Additionally, the implication that parents are not properly taking care of their children's health can inhibit an accurate symptom history.

In a small, nonrandomized controlled trial, the injectable calcitonin gene-related peptide (CGRP) inhibitor erenumab significantly reduced treatment-resistant flushing and erythema associated with rosacea. Skin-related quality-of-life (QOL) measures also improved, albeit modestly.

The study was published in JAMA Dermatology.

National Rosacea Society

“The transient erythema of rosacea is one of the most challenging rosacea symptoms to treat,” Emmy Graber, MD, MBA, who was not involved with the study, said in an interview. “As flushing can adversely impact quality of life in our rosacea patients, it is important to find therapeutic options for our patients. This study is exciting, not only because the treatment was successful for a notable number of patients, but also because it involved a drug with a novel mode of action in rosacea.” Dr. Graber practices in Boston and is an affiliate clinical instructor at Northeastern University, Boston.

Spotlight on CGRP

Rosacea’s pathophysiology remains incompletely understood, wrote Nita K.F. Wienholtz, MD, PhD, Department of Dermatology, Bispebjerg and Frederiksberg Hospital, University of Copenhagen, Denmark, and coinvestigators. However, they added, mounting evidence suggests a possible role for CGRP. For example, a study published in JAMA Dermatology in 2015 revealed elevated CGRP levels in facial skin biopsies from patients with rosacea.

For the present study, the investigators enrolled 30 adults (including 23 women) with rosacea who experienced at least 15 days of moderate to severe erythema or extreme flushing during a 4-week, treatment-free run-in period. Most participants (87%) had previously failed one or more rosacea treatments because of a lack of efficacy or adverse reactions, and 43% had failed three or more treatments.

Participants received 3-monthly 140-mg doses of erenumab, which is approved by the Food and Drug Administration for migraine prevention. Patients recorded scores on the Patient Self-Assessment (PSA) and item 2 of the Flushing Assessment Tool online daily and made a final follow-up visit 12 weeks after the third dose.

Among the 27 patients who completed the study, the mean number of days with moderate to severe flushing from week 9 to week 12 fell by 6.9 from 23.6 days over 4 weeks at baseline (P < .001). Patients most severely affected by flushing at baseline experienced an 81% decline in days with severe to extreme flushing. Overall, 26% of patients experienced at least 50% reductions in moderate to extreme flushing days. The number of days with moderate to severe erythema as measured by PSA fell by 8.1 (mean) from baseline, and 56% of patients experienced at least 50% reductions in PSA scores. No unexpected safety signals emerged.
 

Questions Over QOL Data

“Although there were significant decreases in flushing and erythema,” wrote John S. Barbieri, MD, MBA, in an accompanying Editor’s Note, “the present study had relatively modest improvements in quality of life.” He is director of the Advanced Acne Therapeutics Clinic, Brigham and Women’s Hospital, Boston, and associate editor and evidence-based practice editor of JAMA Dermatology.

Brigham and Women&#039;s Hospital

Compared with baseline (6.22), mean Dermatology Life Quality Index scores fell 2.08 points and 2.73 points at weeks 8 and 20, respectively (P = .004 and .003). At the same intervals, the mean baseline Rosacea Quality of Life score (48.22) decreased by 2.58 points and 4.14 points, respectively (P = .04 and .02).

No significant changes appeared in gauges of anxiety and depression. These findings, authors wrote, could stem from their decision to omit a follow-up visit at week 12 — where they may have seen mental-health effects which disappeared by week 20 — in response to patients’ logistical concerns.

However, Dr. Webster questioned the value of QOL measurements in rosacea. “Quality-of-life measures are blunt instruments,” he explained, and reducing severe itching or chronic pain improves the lives of affected patients. “But what question are you going to ask to tease out whether being less red-cheeked has made someone’s life easier? It’s not a problem that lends itself to quality-of-life assessments.” Moreover, he said, regulators who increasingly require such measures in clinical trials ignore this point, creating challenges for drug developers and researchers.

Because the study was neither blinded nor controlled, Dr. Webster suggested considering it a tantalizing proof of concept. “If I were putting money into a CGRP inhibitor, I’d want at least a small, placebo-controlled, double-blinded study.”

Study authors and Dr. Barbieri recommended larger randomized studies involving different populations and erenumab doses. For now, Dr. Barbieri wrote, CGRP inhibition represents a promising potential strategy for patients who have rosacea with comorbid migraine or recalcitrant flushing and erythema.

Dr. Wienholtz reported no relevant financial interests. Dr. Barbieri had no related disclosures. Dr. Webster reported no relevant financial interests. Dr. Graber reported no conflicts related to erenumab but consults for other companies with rosacea-related products including Galderma. The study was supported by and conducted in collaboration with Novartis Pharma AG. Additional funding came from the Novo Nordisk Foundation and the Lundbeck Foundation.
