Neurotrophic factors have been implicated in hyperalgesia and peripheral levels of these molecules were altered in behavioral and neurological disorders. The objectives of this study were to assess neurotrophic factors levels in migraine patients in comparison with controls, and to investigate whether there was any association between them and clinical parameters. This was a cross-sectional study. We measured serum levels of neurotrophin family members - nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin 3 and 4/5 (NT3 and NT4/5) - and glial cell line-derived factor (GDNF) in patients suffering from migraine and matched controls. One hundred forty-one people were enrolled in this study, seventy-one were migraine patients and seventy were controls. Migraine patients showed more depressive and anxiety symptoms than control individuals as assessed, respectively, by the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory. Chronic and episodic migraine patients showed higher NT4/5 levels than control individuals (P=. 0.001). Patients with chronic migraine had lower levels of BDNF that were not influenced by the presence of depressive symptoms (P=. 0.02). This is the first report to evaluate NT3 and NT-4/5 levels in migraine patients. Our findings suggest a possible role of neurotrophic factors in migraine pathophysiology.
