PACAP38 Induced Headache and Rosacea-like Symptoms in Patients With Rosacea
Investigation of PACAP38-induced Headache and Rosacea-like Symptoms in Patients With Rosacea
Study Overview
Detailed Description
Pituitary adenylate cyclase-activating peptide-38 (PACAP38) plays a role in rosacea pathophysiology. Infusions of PACAP38 can trigger migraine-like attacks in migraine patients. PACAP38 also induces flushing which may imitate rosacea-like flushing. We are investigating whether the flushing after PACAP38 resembles rosacea-like flushing, and whether treatment with sumatriptan has an effect on the headache and flushing effects of PACAP38.
The purpose of this study is to investigate PACAP38-induced headache and flushing in patients with rosacea who have been treated with either sumatriptan or placebo using purpose-developed standardized interview. The investigators will use a double-blind, placebo-controlled crossover study design to investigate this.
