BACKGROUND
Previous studies have proven that 308-nm light-emitting diode(308-nm LED)and 308-nm excimer lamp(308-nm MEL) are effective in treating vitiligo, but there is a lack of comparison of their efficacy for facial lesions.
OBJECTIVE
To evaluate and contrast the treatment success rates of 308-nm LED versus 308-nm excimer lamp in managing facial lesions among patients suffering from stable non-segmental vitiligo.
METHODS
The enrolled 119 patients with 145 lesions were randomly assigned to receive 308-nm LED or 308-nm MEL for two months. Two independent investigators graded repigmentation at the end of the 2-month treatment period.
RESULTS
There were 76 lesions in the 308-nm LED group and 69 in the 308-nm MEL group. After 1 month, the average repigmentation grade of the 308-nm LED group was 1.34, with an efficacy rate of 11.84%, and the average repigmentation grade of the 308-nm MEL group was 1.17, with an efficacy rate of 7.24%.After two months of phototherapy, the average repigmentation grade of the 308-nm LED group was 2.38, and the effective rate was 42.1%. The average repigmentation grade in the 308-nm MEL group was 2.19, and the effective rate was 39.12%. The two light sources had similar effects on facial vitiligo lesions after 1 month and 2 months of treatment(P =.349, P =.416), and the incidence of side effects was also comparable between the two groups (P =.332).
CONCLUSION
The 308-nm LED is as effective and safe as 308-nm MEL in treating stable non-segmental facial vitiligo lesions.
背景
既往研究已证实，308纳米发光二极管（308-nm LED）和308纳米准分子灯（308-nm MEL）在治疗白癜风方面有效，但缺乏对其对面部皮损疗效的比较。
目的
评估并对比308-nm LED与308-nm准分子灯治疗稳定期非节段型白癜风患者面部皮损的成功率。
方法
将纳入的119例患者的145处皮损随机分配，接受308-nm LED或308-nm MEL治疗两个月。两名独立研究者在2个月治疗期结束时对色素恢复情况进行分级。
结果
308-nm LED组有76处皮损，308-nm MEL组有69处皮损。1个月后，308-nm LED组的平均色素恢复分级为1.34，有效率为11.84%；308-nm MEL组的平均色素恢复分级为1.17，有效率为7.24%。光疗2个月后，308-nm LED组的平均色素恢复分级为2.38，有效率为42.1%。308-nm MEL组的平均色素恢复分级为2.19，有效率为39.12%。治疗1个月和2个月后，两种光源对面部白癜风皮损的效果相似（P = 0.349，P = 0.416），两组间副作用发生率也相当（P = 0.332）。
结论
308-nm LED在治疗稳定期非节段型面部白癜风皮损方面与第308-nm MEL同样有效且安全。
