Omega-3 Fatty Acid in the Prevention of Migraine

Omega-3 Fatty Acid in the Prevention of Migraine: From the Randomized Clinical Trial to Molecular Biology Approaches

To understand the clinical efficacy for omega-3 PUFAs migraine prevention.To uncover the underlying biochemical or neurophysiological mechanisms by which omega-3 PUFAs for migraine prevention.

Study Overview

• Status: Completed
• Conditions: Migraine; Omega-3 Polyunsaturated Fatty Acids
• Intervention / Treatment: Dietary supplement: omega-6 PUFAs; Dietary supplement: Omega-3 polyunsaturated fatty acids

Detailed Description

Background:

Migraine is a common disabling disorder and its substantial burden is associated with considerable negative impact on quality of life. Several pharmacological treatments are available for migraine prophylaxis but insufficient efficacy and significant side effects preclude their widely use for migraine treatment. In recent years, more attention has been paid to dietary supplements and natural ingredients for the treatment of migraine. Omega-3 polyunsaturated fatty acids (omega-3 PUFAs) have beneficial on the reduction of neurogenic, perivascular inflammations and pro-inflammatory cytokines, which may play an important role in the pathophysiology of migraine. However, the results of investigations carried out about the clinical efficacy of omega-3 PUFAs in the management of migraine are inconsistent.

Purpose:

To understand the clinical efficacy for omega-3 PUFAs migraine prevention. To uncover the underlying biochemical or neurophysiological mechanisms by which omega-3 PUFAs for migraine prevention

Method:

This two-year project includes clinical approaches to investigate the therapeutic effects of omega-3 PUFAs on episodic migraine (4-14 days/month) without migraine preventive treatment in the past one month. 120 patients, aged 20-65, will be randomized in a 12-week, double-blind, placebo-controlled trial comparing the effects of high-dose eicosapentaenoic acid (EPA, 1.8g/day) and placebo intervention. All participants will complete a set of outcome measures: headache questionnaires and headache diary, the Migraine Disability Assessment (MIDAS), patient overall impression questionnaire-migraine improvement questionnaire (PGI-I), patient overall impression questionnaire-migraine severity questionnaire (PGI-S), Beck Depression Inventory-II (BDI-II), Hospital anxiety and depression scale (HADS), Migraine Quality of Life Questionnaire (MSQ), Pittsburgh Sleep Quality Questionnaire (PSQI) at baseline and the follow-up visits before and after 12 weeks of placebo or omega-3 PUFAs intervention (EPA, 1.8 g/day) and a series of blood tests for neurotransmitter, neurotrophic and neuroinflammation. The clinical efficacy and the peripheral blood biomarkers, will be analyzed at baseline and the end of the intervention.

Expected results:

To establish the clinical evidence of omega-3 PUFAs on migraine prevention. To provide significant insights into molecular actions of omega-3 PUFAs on migraine prevention.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Reduction of migraine attacks during the 12-week period [Efficacy]	The primary end point is the mean change from baseline (28-day pretreatment period) in the mean number of monthly migraine days during the 12-week period. A migraine day was defined as (a day with headache pain that lasted 4 hours with a peak severity of moderate or severe intensity, or any severity or duration if the participant took and responded to a triptan or ergot) from the second to the fourth diaries compared with the first diary (baseline period).	12 weeks
