Abstract

Insights

Migraine and multiple sclerosis (MS) coexistence is linked to lower vitamin D and antioxidant levels, alongside higher oxidative stress markers in relapsing-remitting MS (RRMS) patients. Further research is needed to understand this relationship and its impact on treatment.

Area of Science:

  • Neurology
  • Biochemistry
  • Immunology

Background:

  • Migraine is frequently observed in patients with multiple sclerosis (MS).
  • Understanding the underlying mechanisms of MS and migraine comorbidity is crucial for patient outcomes.
  • This study investigates biochemical markers associated with the coexistence of MS and migraine.

Purpose of the Study:

  • To investigate the relationship between vitamin D metabolism, oxidative stress markers, and the coexistence of relapsing-remitting multiple sclerosis (RRMS) and migraine.
  • To compare these markers in RRMS patients with and without migraine, and healthy controls.
  • To explore potential etiological factors and therapeutic targets for MS-migraine comorbidity.

Main Methods:

  • Cross-sectional study involving 50 RRMS patients with migraine, 50 RRMS patients without migraine, and 50 healthy volunteers.
  • Biochemical analysis of vitamin D, vitamin D-binding protein (VITDBP), vitamin D receptor (VITDR), high-sensitivity C-reactive protein (hs-CRP), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), total antioxidant status (TAS), total oxidant status (TOS), and Oxidative Stress Index (OSI).
  • Data collected between January 1, 2019, and July 25, 2019, at two tertiary hospitals.

Main Results:

  • RRMS patients with migraine exhibited significantly lower vitamin D and VITDR levels compared to those without migraine.
  • Antioxidant markers (SOD, CAT, GSH-Px, TAS) were reduced, while oxidative stress markers (hs-CRP, TOS) were elevated in RRMS patients with migraine.
  • No significant difference in VITDBP levels was observed between RRMS patients with and without migraine.

Conclusions:

  • This study is the first to examine vitamin D and oxidative stress markers in the context of MS and migraine comorbidity.
  • Findings suggest a potential role for vitamin D deficiency and increased oxidative stress in the etiopathogenesis of MS-migraine coexistence.
  • Further research is warranted to elucidate the complex relationship and its clinical implications for developing novel treatments.
