Clinical Trial Summary

Although vitiligo is difficult to cure, recurrences are frequent after treatment, and many patients suffer from concerns about recurrence as well as disease. Psoriasis, another indication for ultraviolet radiation treatment, has been established that it can safely and effectively reduce the recurrence of psoriasis through monthly maintenance therapy.

The aim of this study was to evaluate the efficacy of Narrow-band UV-B therapy for the prevention of relapse in vitiligo.

Description:

For a total period of 12 months, perform Narrow-band UV-B treatment once a month. Check for signs of enlarged vitiligo lesions at 3-month intervals for a total period of 12 months.

An independent evaluator will obtain the score of vitiligo area (Vitiligo Extent Score) from comparing clinical photographs of before registration and after the clinical trial, and judge whether vitiligo is recurred. This study is a randomized controlled trial, and the investigators plan to compare the recurrence rates of the experimental and control groups using the Chi-squared test.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Recurrence of vitiligo	Clinical photographs taken before and 12 months after the completion of the study. The photographs will be used to measure the area of vitiligo lesion, and the investigators will compare the area score and judge whether or not there is a recurrence.	change from baseline area score at 12 months
Secondary	The assessment of patient satisfaction	The assessment of patient satisfaction using five-point Likert scale. (Scale 1: strongly not-satisfied, Scale 2: Not-satisfied, Scale 3: Neither satisfied nor not-satisfied, Scale 4: Satisfied, Scale 5: Strongly satisfied)	at baseline and at 12 months
