Abstract

Depigmentation emerges as a feasible solution for vitiligo universalis and refractory cases of vitiligo vulgaris that hinder patients' quality of life. A range of depigmenting modalities has previously been developed. However, each has its own limitations. Based on skin sensitivity, this study sets out to compare the efficacy and tolerability of "trichloroacetic acid (TCA) peels 25% and 50% and Qs Nd:YAG laser (1,064/532 nm)" for facial depigmentation and "cryotherapy, phenol 88% and Qs Nd:YAG (1,064/532 nm)" for extrafacial skin depigmentation. Forty vitiligo patients were examined and equally divided into facial & extrafacial groups. Regular sessions were performed. Patients' responses were assessed after 3 months or when excellent/complete depigmentation was attained through assessing "depigmentation grade", "extent of depigmented skin", "patient satisfaction" and "overall response". Patients were observed for a six-month follow-up period. In facial depigmentation, Qs Nd:YAG showed the highest significant response followed by TCA 50% and 25%. In extrafacial depigmentation cryotherapy, phenol 88% and Qs Nd:YAG laser displayed positive outcomes without significant difference. Among the modalities tested Qs Nd:YAG yielded superior results in facial residual pigmentation in vitiligo when compared to TCA 50% and 25%, whereas in extrafacial sites Qs Nd:YAG, cryotherapy and phenol were equally effective.

New treatment modalities for vitiligo acting by changing certain cytokines and metalloproteinases are newly emerging. The aim of this work is to To assess the efficacy of trichloroacetic acid (TCA) chemical peel, dermapen, and fractional CO laser in treatment of stable non-segmental vitiligo and to detect their effects on IL-17 and MMP-9 levels. Thirty patients with stable vitiligo were recruited in a randomized controlled study. They were randomly categorized into three equal groups. Group 1: TCA peel, Group 2: dermapen machine, and Group 3: Fractional CO laser. Skin biopsies were taken from treated areas and from control areas for which MMP-9 and IL-17 tissue levels were measured using ELISA. The 30 vitiligo patients had low basal tissue MMP-9 levels and high baseline IL-17 tissue levels. As regards the three different used modalities, all of them caused rise in MMP-9 as well as IL-17 levels and almost their levels were much more elevated with repetition of the previously mentioned traumatic procedures. TCA 25% peel proved to be the most effective modality both clinically and laboratory and it can be used prior or with other conventional therapies in the treatment of vitiligo.
