PACAP38 Induced Headache and Rosacea-like Symptoms in Patients With Rosacea

March 25, 2020 updated by: Nita Katarina Frifelt Wienholtz, Danish Headache Center

Investigation of PACAP38-induced Headache and Rosacea-like Symptoms in Patients With Rosacea

The investigators aim is to investigate the incidence of headache and rosacea-like flushing after pituitary adenylate cyclase-activating peptide-38 (PACAP38) with and without treatment with sumatriptan in patients with rosacea

Study Overview

Status

Completed

Conditions

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.
