Abstract

Monocyte chemotactic and phagocytic responses were assessed in two groups of migraine patients (with and without aura) and in two groups of tension-type headache patients (episodic and chronic). The chemotactic but not the phagocytic response, assessed interictally, is significantly lower in migraine patients (p < 0.006) and in episodic tension-type headache patients, though not so significantly in the latter (p < 0.05), than in the control individuals. The chemotactic response tends to increase significantly during attack in migraine patients both with and without aura (p < 0.008 and p < 0.007 respectively). The same was evident for the phagocytic response in both migraine patient groups (p < 0.007 and 0.0004). No modifications of monocyte functions were found during attacks neither in episodic nor chronic tension-type headache patients. These findings suggest that one or more mediators of neurogenic inflammation having phagocytic and chemotactic enhancing properties (substance P, prostaglandin E and thromboxane A2 etc.) are implicated in the modification of monocyte function. The demonstration of a defect in monocyte function during the interictal period in migraine patients confirms the results of recent research which evidenced reduced capacity of monocyte to phagocyte and kill microorganisms in the course of migraine.
