Abstract

Background and purpose

Migraine is a frequent form of headache. Although many mechanisms describing onset of migraine with and without visual aura have been suggested, the aetiology of migraine headaches is still not clear. Neurogenic inflammation may play a key role in the development of migraine headaches. We evaluated the discriminative power of serum levels of C-reactive protein (CRP) and transforming growth factor beta 1 (TGF-β1) in patients who presented to our clinic with migraine headaches with or without visual aura.

Material and methods

We designed a prospective case-control study of 51 patients with migraine (27 with migraine with aura and 24 with migraine without aura; all had headache) and compared them with 27 healthy subjects during the study period. Demographic and clinical characteristics recorded were age, sex, marital status, occupation, characteristics of headache, laboratory values, and serum CRP and TGF-β1 levels. Statistical analyses used Student t-test, the χ2 test, and ANOVA followed by the post-hoc Bonferroni test for multiple comparisons. Receiver operator characteristic (ROC)-curve analysis for CRP and TGF-β1 was also conducted.

Results

There was no difference between the groups in terms of demographic characteristics, marital status, and socioeconomic status. Statistically, white blood cell levels, serum glucose levels, triglyceride levels, high-density lipoprotein levels, and serum CRP and TGF-β1 were significantly higher in patients with migraine (p < 0.05). The ROC curve results in this study identified that CRP and TGF-β1 may discriminate patients who have different types of migraine headache.

Conclusions

This study suggests that serum CRP and TGF-β1 levels may be diagnostic factors to differentiate migraine patients with and without aura. These findings show that neurogenic inflammation may have a role in the aetiology of migraines.
