ASSOCIATION BETWEEN SERUM LEVELS OF HOMOCYSTEINE WITH CHARACTERISTICS OF MIGRAINE ATTACKS IN MIGRAINE WITH AURA

Background and Aim: The aim of this study was to assess the effects of folic acid alone and in combination with pyridoxine on characteristics of migraine attacks in adult migraine patients with aura.Methods: This clinical trial was conducted on 95 migraine patients with aura (age range 18-65 y) in Isfahan, Islamic Republic of Iran, in 2014. Patients were randomly allocated to receive folic acid (5 mg/d) plus pyridoxine (80 mg/d) or folic acid alone (5 mg/d) or placebo (lactose) for 3 mo. Characteristics of migraine attacks including headache severity, attacks frequency, duration, and headache diary results (HDRs) were obtained for each patient at baseline and at the end of the studyResults: Folic acid plus pyridoxine intake resulted in a significant decrease compared with placebo in headache severity (-2.71 ± 0.08 versus -2.19 ± 0.05; P < 0.001), attack frequency (-3.35 ± 0.09 versus -2.73 ± 0.05; P < 0.001), duration (-7.25 ± 0.17 versus -6.5 ± 0.07; P < 0.001), and HDR (-74.15 ± 0.2 versus -72.73 ± 0.1; P < 0.001). Additionally, the reduction in these characteristics of migraine attacks in the folic acid plus pyridoxine group was significant compared with the group given folic acid alone (P < 0.001). However, these beneficial effects of the combined supplement became nonsignificant for attack duration compared with the folic acid-only and placebo groups after controlling for confoundersConclusion: Supplementation of folic acid with pyridoxine could decrease the characteristics of migraine attacks including headache severity, attack frequency, and HDR;
