Experimental

No Intervention

Arm Label

Experimental group

Control group

Arm Description

For a total period of 12 months, perform Narrow-band UV-B therapy treatment once a month. At this time, the dose of Narrow-band UV-B therapy therapy is based on the 50% of the maximum dose that the patient received for the treatment.

Check for signs of enlarged vitiligo lesions at 3-month intervals for a total period of 12 months. If recurrence of vitiligo is observed during the follow-up period, visit the clinic and check for recurrence.

Outcomes

Primary Outcome Measures

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.

Secondary Outcome Measures

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)

5. Study Description

Brief 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.
Detailed 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.
