Migraine Pain Neurologic Manifestations Signs and Symptoms Brain Diseases Central Nervous System Diseases | Drug: Vasoactive Intestinal Polypeptide (VIP) Drug: Sterile saline | Not Applicable |
The vasoactive intestinal polypeptide (VIP) is a peptide of 28 amino acid residues that belongs to the glucagon/secretin superfamily of peptides. It is distributed in different regions of the nervous system, including several autonomic ganglia and the brain. Once released from neurons, it acts on the vasoactive intestinal peptide receptor 1 (VPAC1), the vasoactive intestinal peptide receptor 2 (VPAC2) and the pituitary adenylate cyclase-activating polypeptide type I receptor (PAC1). All three belong to a family of G-protein coupled receptors, sharing the activation of adenylate cyclase and the increase in intracellular cyclic adenosine monophosphate (cAMP). The three receptors are involved in many physiological functions, among them the vasodilating and parasympathetic responses. VPAC1 and VPAC2 are expressed in dura mater vessels and are primarily responsible for the relaxation of arteries. PAC1 is located in the trigemino-autonomic system, but not in blood vessels. VIP shares the binding to the three aforementioned receptors with other peptides, including the pituitary adenylate cyclase-activating polypeptide-38 (PACAP38), and the pituitary adenylate cyclase-activating polypeptide-27 (PACAP27).
20-minute infusion of VIP and PACAPs in patients with migraine dilated cranial arteries. However, only PACAP27 and PACAP38 induced a sustained cranial vasodilation, and migraine like-attacks. VIP-induced cranial vasodilation was of short duration, and patients did not report migraine-like attacks. The discrepancy was ascribed to the preferential activation of the PAC1 receptor by PACAPs, but a monoclonal antibody against PAC1 receptor recently failed in migraine prevention. Currently, it is unknown whether the prolonged cranial vasodilation related with the appearance of migraine-like attacks. More recently, a two-hour infusion of VIP promoted a long-lasting cranial vasodilation and delayed headache in healthy volunteers, resembling the effect of PACAP27 and PACAP38, two closely related peptides causing migraine. Whether a long-lasting infusion of VIP may induce a sustained cranial vasodilation and migraine-like attacks in migraine patients, as a twenty-minute infusion of PACAP27 and PACAP38, is unknown.

Active Comparator: Vasoactive Intestinal Polypeptide (VIP)
Intravenous infusion of 8 pmol/Kg/min of Vasoactive Intestinal Polypeptide (VIP). The infusion is administered at constant speed by an automatic pump, lasting 120 minutes. |
Drug: Vasoactive Intestinal Polypeptide (VIP)
20 episodic migraine patients without aura of both genders are randomized to receive a 2-hour infusion of VIP and/or sterile saline on two days, with at least one week in between.
Other Name: Vasoactive Intestinal Peptide (VIP) |
Placebo Comparator: Sterile, isotonic, non-active saline (Placebo)
Intravenous infusion of sterile, isotonic, non-active saline 9 mg/ml (placebo). The infusion is administered at constant speed by an automatic pump, lasting 120 minutes.
|
Drug: Sterile saline
20 episodic migraine patients without aura of both genders are randomized to receive a 2-hour infusion of VIP and/or sterile saline on two days, with at least one week in between.
Other Names:
|
- Occurrence of migraine-like attacks [ Time Frame: Before (-10 minutes) and after the drug administration (+12 hours) ]
Migraine-like attack fulfilling either (i) or (ii):
(i) Headache fulfilling criteria C and D for migraine without aura according to the International Classification od Headache Disorders: C. Headache has at least two of the following four characteristics: unilateral location; pulsating quality; moderate or severe pain intensity (moderate pain intensity is considered 5 or 4 on verbal rating scale); aggravation by cough (hospitalization phase) or causing avoidance of routine physical activity (out-hospital phase); D. During headache at least one of the following: nausea and/or vomiting; photophobia and phonophobia; (ii) Headache described as mimicking the patient's usual migraine attack and treated with acute migraine medication (rescue medication).
- Change in cranial hemodynamic [ Time Frame: Before (-10 minutes) and after the drug administration (+3 hours) ]Change on diameter (mm) of superficial temporal artery (STA)
- Occurrence of headache and change of headache intensity scores [ Time Frame: Before (-10 minutes) and after the drug administration (+12 hours) ]Headache intensity scores are measured by a numerical rating scale (NRS). It is a verbally declared scale from 0 to 10, where 0 is no headache; 1 is a very mild headache, including a feeling of pressing or throbbing; 5 is a moderate headache; 10 is the worst imaginable headache.
- Change in Mean Arterial Pressure [ Time Frame: Before (-10 minutes) and after the drug administration (+3 hours and 20 minutes) ]Blood pressure was measured using an auto-inflatable cuff (Protocol, Oregon, USA). Blood pressure was registered as mean arterial pressure (MAP), equal to diastolic blood pressure + 1/3 (systolic blood pressure - diastolic blood pressure).
- Change in Heart Rate [ Time Frame: Before (-10 minutes) and after the drug administration (+3 hours and 20 minutes) ]Heart rate was measured using an auto-inflatable cuff (Protocol, Oregon, USA).
