Anti-Neuroinflammatory Properties of n-3 Fatty Acids and Nano-Curcumin on Migraine Patients, from Cellular to Clinical Insight: A Randomized, Double Blind, and Placebo-Controlled Trial
Abstract
BACKGROUND AND OBJECTIVES
Migraine is an exhausting neuro-inflammatory disorder recognized as recurrent headache attacks. Evidence has shown that Interleukin (IL)-1β plays a substantial role in the neuro-immunity pathogenicity of migraine. n-3 fatty acids and curcumin revealed neuro-modulatory and anti-inflammatory effects through several pathways, of which the suppression of IL-1β gene expression is an important inflammatory pathway. The aim of this study was the investigation of synergistic relation of n -3 fatty acids and nano-curcumin on IL-1β gene expression and serum levels in migraine patients.
METHODS
This study was performed as a randomized double-blind, placebo-controlled trial in the period of two months. A total of 80 episodic migraines were assigned in 4 groups of 1) n-3 fatty acids and curcumin combination; 2) n -3 fatty acids; 3) nano-curcumin; and 4) n-3 fatty acids and curcumin placebo. The gene expression and serum level of IL1β were measured by real-time PCR and ELISA methods respectively, at the beginning and the end of the interventions.
RESULTS
Results showed the n-3 fatty acids and nano-curcumin combination significantly reduced the attack frequency in a synergistic status (P < 0.001). A significantly greater reduction in serum level of IL-1β was observed in the combination group, and the differences in the other groups were not statistically significant. The IL-1β gene expression in combination group showed a significant reduction with respect to…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
