Topical calcipotriene and narrowband ultraviolet B in the treatment of vitiligo.

摘要

Background: Treatment of vitiligo, despite significant advances made in the past few years, remains to be a challenge. Narrowband ultraviolet (NB-UVB) has emerged as an important therapeutic option for this condition. Objective: To evaluate whether the combination of calcipotriene ointment and NB-UVB could enhance the efficacy of NB-UVB alone. Methods: An open, bilateral comparison study was performed in 20 patients with symmetrical vitiligo between August 2001 and October 2002. All patients received NB-UVB three times per week. Calcipotriene ointment was applied to lesions on the left side of the body. Response was graded visually as significant (66-100% repigmentation), moderate (26-65%), mild (10-25%), and minimal (<10%). Results: Seventeen patients (six females, 11 males) completed the study. Eight patients (8/17=47%) had significant repigmentation after 67-180 treatments, six patients (35%), one patient (6%), and two patients (12%) had moderate, mild, and minimal repigmentation after 40-160, 57, and 14-21 treatments, respectively. Nine of the 17 patients had an appreciably better improvement on the NB-UVB and calcipotriene side by 29-114 treatments. In six of these patients, differences were still observed at the end of the study period. No side effects were noted. Conclusion: Combination therapy of topical calcipotriene and NB-UVB is a therapeutic option that could be considered in the management of patients with vitiligo.
