Migraine ICYMI

Patients with migraine, in particular migraine with aura, were more likely to have elevated high sensitivity C-reactive protein (CRP), evident only among those with insomnia, according to a recent cross-sectional study. A total of 20,486 (63%) out of 32,591 individuals, aged 40 years and older, participated in the seventh wave of the Tromsø study conducted in 2015 and 2016, and had valid information on headache, insomnia, and high sensitivity CRP. Researchers found:

• A total of 6290 participants (30.7%) suffered from headache during the last year.
• Among these, 1736 (8.5%) fulfilled the criteria of migraine, 991 (4.8%) had migraine with aura, 746 (3.6%) migraine without aura (3.8%), and 4554 (22.2%) had non-migrainous headache.
• In the final multi-adjusted analysis, elevated high sensitivity CRP was associated with headache, migraine, and migraine with aura.
• No association was found between elevated high sensitivity CRP and migraine without aura or non-migrainous headache.
• The association between high sensitivity CRP and migraine was strongly dependent on insomnia status.
• Among individuals with insomnia, elevated high sensitivity CRP was associated with migraine, and migraine with aura, whereas no such relationship was found among those without insomnia.

Although results of a recent study are preliminary, spinal manipulation may be an effective therapeutic technique to reduce migraine days and pain/intensity. Literature databases were searched for clinical trials that evaluated spinal manipulation and migraine‐related outcomes through April 2017. Search terms included: migraine, spinal manipulation, manual therapy, chiropractic, and osteopathic. Meta‐analytic methods were employed to estimate the effect sizes (Hedges’ g) and heterogeneity (I²) for migraine days, pain, and disability. Researchers found:

• Six randomized clinical trials (RCTs) (pooled n=677; range of n=42‐218) were eligible for meta‐analysis.
• Intervention duration ranged from 2 to 6 months; outcomes included measures of migraine days (primary outcome), migraine pain/intensity, and migraine disability.
• Due to high levels of heterogeneity when all 6 studies were included in the meta‐analysis, the 1 RCT that was performed only among chronic migraineurs was excluded.
• Heterogeneity across the remaining studies was low.
• Spinal manipulation reduced migraine days with an overall small effect size (Hedges’ g=−0.35) as well as migraine pain/intensity.

STOWE, VT. – “The eye is intimately involved in the migraine process,” said Kathleen Digre, MD, at the annual meeting of the Headache Cooperative of New England. Specifically, she said, dry eye and photophobia are two symptoms that have biologic underpinnings, can be diagnosed, and can be treated. Dr. Digre is a professor of neurology and ophthalmology at the University of Utah, Salt Lake City, and is the current president of the American Headache Society.

Dr. Digre explained that dry eyes and migraine could have a cyclical relationship where dry eyes provoke the migraine, and the migraine may provoke the feeling of dry eye, regardless of whether it can be objectively measured.

Regarding photophobia, Dr. Digre stressed the importance of an accurate diagnosis that rules out eye disorders and other causes of photophobia. She discussed the problem of patient overreliance on dark glasses and encourages a return to light to break the cycle of dark adapting the retina.

Finally, Dr. Digre discussed how proper treatment of migraine and any associated anxiety or depression can help resolve eye issues that may be contributing to migraine.

STOWE, VT. – These are the early days of the “CGRP monoclonal antibody era,” Peter McAllister, MD, said in a summary of the current status of calcitonin gene-related peptide monoclonal antibodies for migraine prevention. He discussed what has been learned in the clinical trials of these drugs as well as in the first 10 months of having them on the market.

Vidyard Video

In an interview at the annual meeting of the Headache Cooperative of New England, Dr. McAllister said, “We are comforted that we have now 1-year, 3-year, and 5-year data” from clinical trials, but the sample size is small.

In the time since the first three drugs were approved, “we have probably in the ballpark of over 200,000 patients who have received a monoclonal antibody, and so far there has been nothing that makes us stop cold in our tracks and say there’s something wrong here. That is very comforting,” he said. Dr. McAllister is the medical director of the New England Institute for Neurology and Headache in Stamford, Conn.

What is still unknown, however, is the long-term safety and efficacy; what happens in a larger pool of patients taking these drugs; what happens in pregnancy and effects on the fetus; how and when to safely switch from one monoclonal antibody to another; the systemic effects of these drugs; and other concerns that may arise in postmarketing studies.

Persons with migraine show individual attack patterns and weekend migraine can be determined for a subgroup of participants, while others show accumulations of their attacks on other days of the week. This according to a recent analysis of migraine attacks collected online within the project Migraine Radar in respect to the distribution of migraine attacks throughout the week on a single‐participant level. Researchers recorded data using a web app as well as smartphone apps in order to collect data of 44,639 migraine attacks of 1085 participants who reported 7 or more attacks during a period of at least 90 days. They found:

• For 15.9% of the participants, the attacks were not distributed equally throughout the days of the week.
• Instead, participants show different individual patterns for the distribution of their migraine attacks.
• Furthermore, the modes of the individual distributions are not distributed equally throughout the week.
• Saturday seems to be the predominant day for migraine attacks for a greater proportion of participants (195 of 1085).

Raising awareness among clinicians that many of the potential variables contributing to the presence of migraine are modifiable (eg, psychological problems and lifestyle behaviors) might intensify resources dedicated to assessing and impacting these factors in order to potentially prevent the frequency and severity of migraine. This according to a recent study that aimed to identify the modifiable and non-modifiable variables that are associated with, and might moderate, the presence of migraine in the general population. Using a nationally representative cross-sectional survey, researchers evaluated responses from individuals aged 15 years and older (n=22,842). There was a secondary analysis of data from the second wave of a health interview survey conducted from 2014 to 2015. They found:

• The 1-year prevalence of migraine was 8%.
• The final multivariate model (Wald χ²=693.00, df=15) retained depression severity, chronic anxiety, exercising several times a month or week, and alcohol use as predictors of migraine (odds ratios=2.1–3.5 for positive associations, odds ratios=0.4–0.9 for negative associations).

Non-persistence to prophylactic treatment was frequent among migraine patients, a recent study found. Furthermore, opioid use was common in migraine patients and the risk of gastrointestinal-related adverse events and opioid abuse increased with long-term use of opioids. These results suggest a need for more effective prophylactic migraine treatments. This study used the IBM MarketScan databases from 2005 through 2014 to evaluate migraine patients initiating prophylactic medication. In total, 147,832 patients were analyzed. Outcome measures included persistence with prophylactic migraine medications throughout 2 to 5 years. Acute medication use and gastrointestinal-related adverse events and opioid abuse following opioid use were evaluated. Researchers found:

• Non-persistence was observed in 90% of patients; 39% switched, 30% restarted, and 31% discontinued treatment.
• Throughout the follow-up, 59.9% of patients received triptans, 66.6% non-steroidal anti-inflammatory drugs, 77.4% opioids, and 2.6% ergotamines.
• Among opioid users, 16.6% experienced nausea/vomiting, 12.2% had constipation, and 10.4% had diarrhea.
• Opioid abuse was reported in <1% of opioid users.
• Gastrointestinal-related adverse events increased with increasing number of days’ supply of opioids.

DALLAS – In a cohort of patients with multiple sclerosis, a history of migraine was associated with more severe disability and significantly slower walking speeds, researchers reported at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis.

“Traditional migraine risk factors such as obesity, anxiety, and depression were also overrepresented in our cohort” of patients with multiple sclerosis (MS) and migraine, said Anne M. Damian, MD, of Johns Hopkins University, Baltimore, and her research colleagues.

Migraine is common in patients with MS, but whether migraine plays a role in MS disease course or MS symptom severity is unknown. Dr. Damian and her colleagues conducted an observational study to examine the associations between migraine history, disability, and neurologic function in patients with MS and whether migraine tends to occur with other comorbid conditions in MS.

They analyzed data from 289 patients (79% female; mean age, 49.2 years) patients with MS who completed the Multiple Sclerosis Performance Test (MSPT), an iPad version of the MS Functional Composite. MS outcome measures included disability (such as the Patient Determined Disease Steps) and objective neurologic outcomes (such as walking speed, manual dexterity, and processing speed). Patients also completed a questionnaire about comorbidities, including history of physician-diagnosed migraine, diabetes, hypertension, hypercholesterolemia, heart disease, sleep apnea, depression, and anxiety.

The researchers used generalized linear models adjusted for age, sex, MS subtype, MS duration, years of education, and body mass index to evaluate the association between history of migraine and MS outcomes.

Compared with patients with MS without migraine, migraineurs (n = 65) tended to be younger (mean age, 44.3 years vs. 50.4 years) and were more likely to be overweight or obese (73.9% vs. 51.6%). In addition, patients with MS and migraine were more likely to have a history of depression (46.2% vs. 24.2%), anxiety (30.8% vs. 18.8%), and severe rather than mild disability (odds ratio, 3.08; 95% confidence, 1.04-9.20). Migraine also was associated with significantly slower walking speeds (9.08% slower; 95% CI, 0.82%-18.77%). Migraine was not associated with processing speed or manual dexterity, however.

If an association between migraine history and worse MS disability is confirmed, migraine history may be a factor that neurologists could consider when making MS treatment decisions, Dr. Damian said. The researchers noted that migraine was reported by patients and not detected using a validated questionnaire. Future studies should investigate whether MS lesions on MRI differ in migraineurs and whether migraine predicts future neurologic disability in patients with MS.

Collection of the MSPT outcomes was sponsored by Biogen.

In addition, patients with MS and migraine were more likely to have a history of depression (46.2% vs. 24.2%), anxiety (30.8% vs. 18.8%), and severe rather than mild disability (odds ratio, 3.08; 95% confidence, 1.04-9.20). Migraine also was associated with significantly slower walking speeds (9.08% slower; 95% CI, 0.82%-18.77%). Migraine was not associated with processing speed or manual dexterity, however.

If an association between migraine history and worse MS disability is confirmed, migraine history may be a factor that neurologists could consider when making MS treatment decisions, Dr. Damian said. The researchers noted that migraine was reported by patients and not detected using a validated questionnaire. Future studies should investigate whether MS lesions on MRI differ in migraineurs and whether migraine predicts future neurologic disability in patients with MS.

DALLAS – In a cohort of patients with multiple sclerosis, a history of migraine was associated with more severe disability and significantly slower walking speeds, researchers reported at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis.

“Traditional migraine risk factors such as obesity, anxiety, and depression were also overrepresented in our cohort” of patients with multiple sclerosis (MS) and migraine, said Anne M. Damian, MD, of Johns Hopkins University, Baltimore, and her research colleagues.

Migraine is common in patients with MS, but whether migraine plays a role in MS disease course or MS symptom severity is unknown. Dr. Damian and her colleagues conducted an observational study to examine the associations between migraine history, disability, and neurologic function in patients with MS and whether migraine tends to occur with other comorbid conditions in MS.

They analyzed data from 289 patients (79% female; mean age, 49.2 years) patients with MS who completed the Multiple Sclerosis Performance Test (MSPT), an iPad version of the MS Functional Composite. MS outcome measures included disability (such as the Patient Determined Disease Steps) and objective neurologic outcomes (such as walking speed, manual dexterity, and processing speed). Patients also completed a questionnaire about comorbidities, including history of physician-diagnosed migraine, diabetes, hypertension, hypercholesterolemia, heart disease, sleep apnea, depression, and anxiety.

The researchers used generalized linear models adjusted for age, sex, MS subtype, MS duration, years of education, and body mass index to evaluate the association between history of migraine and MS outcomes.

Compared with patients with MS without migraine, migraineurs (n = 65) tended to be younger (mean age, 44.3 years vs. 50.4 years) and were more likely to be overweight or obese (73.9% vs. 51.6%).

Migraine is associated with aberrant connections from the somatosensory cortex to the frontal lobe, according to a recent study. The frequency-specific increases in connectivity in terms of strength, path length, and clustering coefficients support the notion that migraineurs have elevated cortical networks. Twenty-two migraineurs in the interictal phase and 22 sex- and age-matched healthy volunteers were studied using a whole-head magnetoencephalography (MEG) system. Researchers found:

• The brain network patterns revealed that the patients with migraine exhibited remarkably increased functional connectivity in the high-frequency (250–1000 Hz) band between the sensory cortex and the frontal lobe.
• The results of quantitative analysis of graph theory showed that the patients had:

1. an increased degree of connectivity in the theta (4–8 Hz), beta (13–30 Hz) and gamma (30–80 Hz) bands;
2. an increased connectivity strength in the beta (13–30 Hz) and gamma (30–80 Hz) bands;
3. an increased path length in the beta (13–30 Hz), gamma (30–80 Hz) and ripple (80–250 Hz) bands; and
4. an increased clustering coefficient in the theta (4–8 Hz), beta (13–30 Hz) and gamma (30–80 Hz) bands.

Migraine is more frequent in patients with subclinical hypothyroidism in respect to controls, according to a recent study. Using a case-control strategy, 151 consecutive subclinical hypothyroidism patients (mean age 48.36 ± 15.86 years) and 150 controls (mean age 50.86 ± 9.19 years) were recruited. In all subjects, migraine characteristics were collected through a direct interview. Clinical and biochemical parameters (thyroid-stimulating hormone, free triiodothyronine, free thyroxine, and anti-thyroid antibodies) were compared between subclinical hypothyroidism patients in comorbidity with migraine and subclinical hypothyroidism patients without migraine. Researchers found:

• The prevalence of lifetime migraine was significantly higher in subclinical hypothyroidism patients in comparison with controls (46% vs 13%; OR 5.80).
• Both migraine without and with aura were significantly higher in subclinical hypothyroidism patients than controls.
• Thyroid hormones and concentrations of antibodies did not differ between subclinical hypothyroidism patients with and without migraine.
• Interestingly, a comorbidity for autoimmune diseases was observed in subclinical hypothyroidism patients with migraine in respect to those without migraine.
