Patient reported outcomes for intensified versus conventional NB-UVB treatment in non-segmental vitiligo

Abstract

Introduction: Treatment of non-segmental vitiligo (NSV) remains a challenge. Efficacy of NB-UVB treatment may increase with more frequent use or in combination with topical agents. Currently, data on the most effective treatment regimen lacking. Our objective is to retrospectively compare NB-UVB treatment regimens for non-segmental vitiligo.

Methods: Patients with NSV treated with NB-UVB therapy were included in two time periods. Group I received NB-UVB therapy twice a week (conventional treatment) and group II received NB-UVB thrice a week, combined with topical agents (intensified treatment). Patients completed a questionnaire regarding the degree and onset of repigmentation, satisfaction and side effects.

Results: Repigmentation scores did not differ significantly between the two groups. Onset of repigmentation in the first three months seemed higher in group II, but this difference was not significant (23.4% vs 51.1%; p = .11). In both groups the majority of the patients were moderately to very satisfied (group I: 70.2% group II: 73.3%). The occurrence of adverse effects was comparable.

Conclusions: This study indicates that conventional and intensified treatment for NSV seem to be comparable. The intensified treatment might be more effective to speed up the onset of repigmentation, but larger prospective studies are needed to objectify these findings.
