The Efficacy of Hand Narrow-Band Ultraviolet B (NBUVB) Versus Excilite Treatment in Vitiligo After Minigrafting on the Dorsal Hands

The Efficacy of Hand-Foot Narrow-Band Ultraviolet B (UVB) Versus Focal 308-nm Treatment in Inducing Repigmentation of Vitiligo After Minigrafting on the Dorsal Hands

To assess over a 25-week period the efficacy of hand-foot narrow-band ultraviolet B light versus focal 308-nm light treatment in inducing the return of pigment in vitiligo after skin minigraft transplants to the backs of the hands in patients with light brown to black skin. Subject will undergo treatment for 13 weeks.

Prospective investigator-blinded study involving 13 adult male and female subjects with vitiligo on the backs of both hands. Punch minigrafting will be performed on both hands taking skin from the thighs and/or buttocks. Light treatments will be administered starting at week one after grafting. One hand will receive narrow-band ultraviolet B light and the other will receive focal 308-nm light treatments. Light treatments will be administered 3 times per week for 12 weeks. A long term follow-up visit will be completed at week 25. The investigator will evaluate the subjects at week 4, 7, 13 and 25 in addition to screening and baseline evaluations/procedures.
