About this study
Official title: The Effect of PACAP27 on the Extra- and Intracerebral Arteries Assessed by MRA on Healthy Volunteers
Studying Pituitary adenylate cyclase-activating peptide 27 (PACAP27) effects on extra- and intracerebral arteries assessed by MRA on healthy volunteers.
Read the detailed description
PACAP neuropeptide, which belongs to the vasoactive intestinal polypeptide (VIP)/glucagon/secretin family. PACAP exists in two forms: Studying Pituitary adenylate cyclase-activating peptide 38 (PACAP38), which consists of 38 amino acids and PACAP27 which contains 27 amino acids at its N-terminus. PACAP38 is implicated in migraine pathophysiology however PACAP27 is not studied well. Therefore, the investigators will study PACAP27's effect on extra- and intracerebral arteries assessed by MRA on healthy volunteers.

| Study group | Role | What they receive |

| PACAP27 | Active comparator | 12 healthy volunteers will receive PACAP27 (10 picomole/kg/min) over 20 min Receives: Other: PACAP27 |

What is being measured
The primary outcome is the main question the study is designed to answer.
Dilation of extra- and intracerebral arteries
A single-slab 3D time-of-flight (3D TOF) MRA of extra- and intracranial arteries will be acquired as described in previous studies (Amin et al., 2013, 2014). MRA data will be analyzed by LKEB-MRA vessel wall analysis software program. We will measure the circumference of vessels in millimeter in five predefined time points (0, 20, 110, 200 and 290 min)
Measured: 0-290 min
Secondary outcomes (1)
Headache
Headache intensity (Visual analog scale 0-10), characteristics, location and migraine associated symptoms will be recorded in questionnaire at hospital (6 hours) and post hospital (18 hours). In hospital phase, headache questionnaire will be filled every 30 min and post hospital every hour.
Measured: 0 to 24 hours
