Key clinical point: Interictal levels of plasma glutamate are elevated in patients with episodic migraine (EM) and chronic migraine (CM), thus qualifying it as a potential marker for both EM and CM.
Major finding: Plasma glutamate levels were significantly higher in patients with EM (49.73 μmol/L [95% CI 40.82-66.12] ) and CM (58.70 μmol/L [95% CI 44.64-72.46]) vs control participants (38.79 μmol/L [95% CI 29.50-53.60]; P < .001).
Study details: This single-center study included 240 women aged 19-65 years, of which 98 had EM, 92 had CM, and 50 were nonmigraine control participants.
Disclosures: The study was supported by a National Research Foundation of Korea (NRF) grant from the Korean government. MK Chu declared serving as a site investigator for a multicenter trial and an advisory member for and receiving lecture honoraria and grants from various organizations, including NRF.
