Abstract
BACKGROUND
A light emitting diode (LED), with a wavelength of 308 nm, has been utilized in the dermatologic treatment of vitiligo.
OBJECTIVES
We investigated the efficacy and safety of 308-nm LED for use in the treatment of vitiligo.
METHODS
We conducted a retrospective study of 70 stable-stage vitiligo patients (with a total of 99 lesions) who received 308-nm LED treatment at the Institute of Dermatology, Chinese Academy of Medical Sciences and Peking Union Medical College from June 2018 to June 2020. Treatment efficacy was evaluated after 8 treatment sessions, 16 treatment sessions, and the final treatment session, to estimate the percentage of re-pigmentation in the treated area. The Kruskal-Wallis test was used for data analysis.
RESULTS
Based on the final treatment session analysis of all 99 lesions, 0 lesions showed no response, 21 lesions showed poor response, 29 lesions showed moderate response, 23 lesions showed good response, and 26 lesions showed excellent response. The efficacy rate was 49.49%, and there was a significant correlation between the six distinct anatomical regions treated and re-pigmentation grade (χ2 = 13.419, p = .009). Among these regions, facial lesions showed the best response to treatment, while the hands and feet lesions showed the poorest response.
CONCLUSIONS
The clinical efficacy of 308-nm LED treatment is limited based on the treatment area. It demonstrated significant practical application in the treatment of vitiligo.
