Maintenance Therapy of 308-nm Excimer Laser Therapy in Patients With Vitiligo

The Catholic University of Korea100 enrolled

Overview

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 308-nm excimer laser therapy for the prevention of relapse in vitiligo.

For a total period of 12 months, perform the 308-nm excimer laser 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.

Outcomes

Primary Outcomes

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.

Time frame: Change from Baseline area score at 12 months

Secondary Outcomes

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)

Time frame: at Baseline and at 12 months
