The effects of nano-curcumin supplementation on Th1/Th17 balance in migraine patients: A randomized controlled clinical trial
Abstract
BACKGROUND
The present study was aimed to evaluate the nano-curcumin supplementation on Th1/Th17 balance by assessment of gene expression and serum level of interferon gamma (IFN-γ) and interleukin-17 (IL-17) in migraine patients.
METHODS
Forty participants with episodic migraine were randomly allocated to receive 80 mg nano-curcumin (n = 20) or placebo (n = 20) in a randomized double-blind clinical trial for two months. The expression of IFN-γ and IL-17 from peripheral blood mononuclear cells and IFN-γ and IL-17 serum levels were measured, using a real-time PCR and ELISA methods, respectively.
RESULTS
Compared to placebo group, two month nano-curcumin supplementation led to a significant reduction in serum levels and expression of IL-17 mRNA (P = 0.006 & 0.04, respectively), while there was no statistical difference regarding serum levels and expression of IFN-γ mRNA.
CONCLUSION
Nano-curcumin supplementation in migraine patients led to a significant reduction in gene expression and plasma levels of IL-17 compared to control group.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 20 participants or records.
