Determining the Tolerance of Depigmented Skin to Targeted Phototherapy Using UVB in Patients With Vitiligo
The purpose of this study is to determine if vitiligo patients develop tolerance to ultraviolet light therapy, a type of treatment available for vitiligo.
|Official Title:||Determining the Tolerance of Depigmented Skin to Targeted Phototherapy Using UVB in Patients With Vitiligo|
|Study Start Date:||January 2006|
|Study Completion Date:||May 2008|
|Primary Completion Date:||May 2008 (Final data collection date for primary outcome measure)|
Procedure: 6 to 9 ultraviolet B treatments
Patients with vitiligo received 6-9 ultraviolet B treatments, 2 to 3 times weekly. Minimal erythema dose (MED) testing was done at baseline and after all treatments; the percent change in MED was analysed as a measure of photoadaptation. The percent decrease in cyclobutane pyrimidine dimers (CPDs) over 24 hours after a single exposure of 1 MED was analysed on vitiliginous and normal skin.
