- Public TitleRosacea and the Subpurpuric pulsed dye laser treatment Efficacy
- Scientific TitleRosacea and the Subpurpuric pulsed dye laser treatment Efficacy
- ACRONYMRoSE
- hypothesisWe hypothesize that the experimental 2-week interval will neither cause a difference in burden nor in risks. It probably will lead to better results and it has the advantage that the total duration of treatment is shorter.

- Target number of participants58
- InterventionsSubjects receive subpurpuric Pulsed Dye Laser (PDL) treatments until their visible telangiectasia are disappeared with a maximum of 4 treatments, separated by either a 2-week interval (Arm 1) or an 8-week interval (Arm 2).
- Primary outcome• Health Related Quality of Life (HRQoL) measurement as a patient reported outcome (PRO) by using the RosaQol, a rosacea-specific HRQoL questionnaire
• Blinded evaluation of photographs by using the Investigators Global Assessment (IGA)
- Secondary outcome• Blinded evaluation of photographs by
- using Clinician's Erythema Assessment (CEA)
- grading of severity of telangiectasia Patient’s Global Assessment (PGA)
- TimepointsPatients will be seen at screening and at 2 weeks or 8-weeks interval between the treatments, with a maximum of 4 treatments. Follow up 8-10 weeks ana 1 year after last treatment.

- Brief summaryPDL therapy is used worldwide for erythematotelangiectatic rosacea. Subpurpuric PDL treatment is characterized by using a fluence that is just below the purpura threshold of the patient. With these settings posttreatment side effects such as purpura can be avoided. Lasers and accompanying settings improved a lot since introduction, but optimal therapy parameters and intervals between treatments have not yet been decided.
