Inflammatory mediators have been studied in migraine pathophysiology; however, their role is not yet well established. The aim of the present study was to investigate interictal chemokine levels and its association with clinical parameters and psychiatric comorbidities in migraine patients compared with controls. This was a cross-sectional study including age and gender matched migraine patients and controls. Beck Depression and Anxiety Inventories, Headache Impact Test, and Allodynia Symptom Checklist were recorded. Chemokines were measured by ELISA. Forty-nine migraine patients and forty-nine controls without headache were included. CXCL8/IL-8 and CCL3/MIP-1 alpha levels were significantly higher among patients with migraine (P = 0.039 and 0.02, respectively) even after controlling for anxiety and depression scores. Chemokine levels were not correlated with migraine impact as well as allodynia scores. CXCL8/IL-8 and CCL3/MIP-1 alpha levels were raised in migraine, independently of psychiatric comorbidities, migraine impact, and allodynia.
