BackgroundActivation of the trigeminal-autonomic reflex, involving the trigeminal ganglion, the superior salivatory nucleus and the sphenopalatine ganglion SPG is crucial in the pathophysiology of cluster headache CH. Since pituitary adenylate cyclase-activating polypeptide-38 PACAP-38 is present both in the SPG and the trigeminal ganglion TG and its role in migraine has been described, our aim was to determine the plasma PACAP-38 levels in different phases of episodic CH ECH.

Peripheral cubital fossa blood samples were taken during the ictal and inter-bout periods of male ECH patients and from age-matched healthy controls n = 9. Plasma PACAP-38-like immunoreactivity LI was measured with specific and sensitive radioimmunoassay.

FindingsSignificantly lower plasma PACAP-38-LI was detected in the inter-bout period of ECH patients than in healthy controls. However, PACAP-38 was significantly elevated in the plasma during CH attacks as compared to the inter-bout phase in the same subjects n = 5.

ConclusionsThis exploratory study suggests that PACAP-38 may be released during the attacks of ECH. Further patients and long-term follow-up are necessary to reveal its function.
