Due to inconclusive findings of previous researches, we aimed to evaluate inflammatory state biomarkers in episodic and chronic migraineurs (EM and CM patients) compared to headache-free controls in the current study.
Seventy-one migraine patients and 19 age-sex-matched controls were recruited. After obtaining demographic data and recording headache characteristics, blood samples were gathered and analyzed to evaluate the serum levels of C-reactive protein (CRP), tumor necrosis factor(TNF)-α and interleukin (IL)-6.
Serum levels of IL-6, CRP and TNF-α were significantly higher among subjects with CM than the EM and controls. Further, positive correlations were noted for number of headache days/month and serum IL-6 (r=0.53, p<0.001), CRP (r=0.62, p<0.001), and TNF-α (r=0.58, p<0.001).
In sum, according to current findings, a pro-inflammatory state was detected among chronic and episodic migraineurs compared to healthy control, as revealed by augmented concentrations of pro-inflammatory cytokines (e.g. IL6, CRP, and TNF-α). It was also underlined that with increasing levels of inflammatory factors, headaches tended to be more chronic. However, in order to confirm the hypothesis that neuroinflammation plays a role in migraine pain genesis, long-term cohort studies and well-designed experimental and randomized controlled trials are required.
