Prevention of Episodic Migraine Headache Using Pharmacologic Treatments in Outpatient Settings: A Clinical Guideline From the American College of Physicians

Author/s: 
Amir Qaseem, Thomas G Cooney, Itziar Etxeandia-Ikobaltzeta, Timothy J Wilt

The American College of Physicians (ACP) developed this clinical guideline for clinicians caring for adults with episodic migraine headache (defined as 1 to 14 headache days per month) in outpatient settings.

Methods: ACP based these recommendations on systematic reviews of the comparative benefits and harms of pharmacologic treatments to prevent episodic migraine, patients' values and preferences, and economic evidence. ACP evaluated the comparative effectiveness of the following interventions: angiotensin-converting enzyme inhibitors (lisinopril), angiotensin II-receptor blockers (candesartan and telmisartan), antiseizure medications (valproate and topiramate), β-blockers (metoprolol and propranolol), calcitonin gene-related peptide (CGRP) antagonist-gepants (atogepant or rimegepant), CGRP monoclonal antibodies (eptinezumab, erenumab, fremanezumab, or galcanezumab), selective serotonin reuptake inhibitors and serotonin and norepinephrine reuptake inhibitors (fluoxetine and venlafaxine), and a tricyclic antidepressant (amitriptyline). ACP used the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach to analyze the effects of pharmacologic treatment on the following outcomes: migraine frequency and duration, number of days medication was taken for acute treatment of migraine, frequency of migraine-related emergency department visits, migraine-related disability, quality of life and physical functioning, and discontinuations due to adverse events. In addition, adverse events were captured through U.S. Food and Drug Administration medication labels and eligible studies.

Recommendations: In this guideline, ACP makes recommendations for clinicians to initiate monotherapy for episodic migraine prevention in nonpregnant adults in the outpatient setting as well as alternative approaches if initial treatments are not tolerated or result in an inadequate response. All 3 ACP recommendations have conditional strength and low-certainty evidence. Clinical considerations provide additional context for physicians and other clinicians.

Diagnosis and acute management of migraine

Author/s: 
Tzankova, V., Becker, W. J., Chan, T. L. H.

Migraine is a leading cause of disability across all age groups.
• Routine imaging is not recommended in patients with migraine
who have no red flags, atypical symptoms or abnormal findings
on neurologic examination.
• A stratified approach for acute migraine treatment empowers
patients to choose from different treatment options
depending on attack symptoms and severity and encourages
patients to combine medications from different classes.
• Effective acute migraine treatment includes acetaminophen,
nonsteroidal anti-inflammatory drugs and triptans.
• Ubrogepant and rimegepant are new, effective migraine
treatments, suitable for patients with cardiovascular disease in
whom triptans are contraindicated.

Migraine — Treatment and Preventive Therapies

Author/s: 
Armand, C.E., Loder, E., Ropper, A. H.

In this instructional video, Drs. Cynthia Armand and Elizabeth Loder discuss the clinical presentation and pathophysiology of migraine and treatment options for patients.

This video provides essential and useful information for any clinician caring for patients with this common condition. Newer acute and preventive therapies — including triptans, gepants, ditans, and injectable monoclonal antibodies — are discussed, as are the importance of a patient-centered approach and the need to tackle challenges of access to these newer agents.

Craniosacral therapy for chronic pain: a systematic review and meta-analysis of randomized controlled trials

Author/s: 
Haller, H, Lauche, R, Sundberg, T, Dobos, G, Cramer, H

OBJECTIVES:

To systematically assess the evidence of Craniosacral Therapy (CST) for the treatment of chronic pain.

METHODS:

PubMed, Central, Scopus, PsycInfo and Cinahl were searched up to August 2018. Randomized controlled trials (RCTs) assessing the effects of CST in chronic pain patients were eligible. Standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated for pain intensity and functional disability (primary outcomes) using Hedges' correction for small samples. Secondary outcomes included physical/mental quality of life, global improvement, and safety. Risk of bias was assessed using the Cochrane tool.

RESULTS:

Ten RCTs of 681 patients with neck and back pain, migraine, headache, fibromyalgia, epicondylitis, and pelvic girdle pain were included. CST showed greater post intervention effects on: pain intensity (SMD = -0.32, 95%CI = [- 0.61,-0.02]) and disability (SMD = -0.58, 95%CI = [- 0.92,-0.24]) compared to treatment as usual; on pain intensity (SMD = -0.63, 95%CI = [- 0.90,-0.37]) and disability (SMD = -0.54, 95%CI = [- 0.81,-0.28]) compared to manual/non-manual sham; and on pain intensity (SMD = -0.53, 95%CI = [- 0.89,-0.16]) and disability (SMD = -0.58, 95%CI = [- 0.95,-0.21]) compared to active manual treatments. At six months, CST showed greater effects on pain intensity (SMD = -0.59, 95%CI = [- 0.99,-0.19]) and disability (SMD = -0.53, 95%CI = [- 0.87,-0.19]) versus sham. Secondary outcomes were all significantly more improved in CST patients than in other groups, except for six-month mental quality of life versus sham. Sensitivity analyses revealed robust effects of CST against most risk of bias domains. Five of the 10 RCTs reported safety data. No serious adverse events occurred. Minor adverse events were equally distributed between the groups.

DISCUSSION:

In patients with chronic pain, this meta-analysis suggests significant and robust effects of CST on pain and function lasting up to six months. More RCTs strictly following CONSORT are needed to further corroborate the effects and safety of CST on chronic pain.

Aspirin in the Treatment and Prevention of Migraine Headaches: Possible Additional Clinical Options for Primary Healthcare Providers

Author/s: 
Biglione, B., Gitin, A., Gorelick, P., Hennekens, C.

Migraine headaches are among the most common and potentially debilitating disorders encountered by primary healthcare providers. In the treatment of acute migraine as well as prevention of recurrent attacks there are prescription drugs of proven benefit. For those without health insurance or high co-pays, however, they may be neither available nor affordable and, for all patients, they may be either poorly tolerated or contraindicated.

The totality of evidence, which includes data from randomized trials, suggests that high-dose aspirin, in doses from 900 to 1300 milligrams, taken at the onset of symptoms, is an effective and safe treatment option for acute migraine headaches. In addition, the totality of evidence, including some, but not all, randomized trials, suggests the possibility that daily aspirin in doses from 81 to 325 milligrams, may be an effective and safe treatment option for the prevention of recurrent migraine headaches.

The relatively favorable side effect profile of aspirin and extremely low costs compared with other prescription drug therapies may provide additional options for primary healthcare providers treating acute as well as recurrent migraine headaches.
