Key clinical point: Two months of supplementation with omega-3 fatty acids had favorable effects on inflammatory and anti-inflammatory markers in patients with episodic migraine.
Major finding: After 2 months of treatment, the serum concentration of anti-inflammatory interleukin-4 (IL-4) was significantly increased (P = .010) whereas that of proinflammatory interferon gamma was significantly decreased (P = .001) in the omega-3 supplementation vs placebo group. The serum concentration of transforming growth factor beta or IL-17 was not significantly different between the groups.
Study details: The data come from a randomized controlled trial including 40 patients with episodic migraine who were randomly assigned to receive omega-3 supplementation (2 capsules/day; each capsule containing 600 mg eicosapentaenoic acid and 300 mg docosahexaenoic acid; n = 20) or placebo (paraffin oil capsules; n = 20) for 2 months.
Disclosures: This study did not receive any funding. The authors declared no potential conflicts of interest.
