Comparative study between excimer light and topical antioxidant versus excimer light alone for treatment of vitiligo

Background: Vitiligo is an acquired idiopathic cutaneous disease characterized by pearly white patches of variable shapes and sizes. Various medical and surgical therapeutic options have been proposed to achieve repigmentation; phototherapy is one of the most efficient options. Topical therapies have been a mainstay of vitiligo treatment, with or without phototherapy. Aim of the work: To compare the efficacy of combined topical antioxidant hydrogel and excimer light versus excimer light alone in treating vitiligo. Patients and Methods: Thirty patients were included in this comparative, prospective, randomized study. For each patient, at least 2–4 vitiliginous macules were randomly selected and treated while an untreated vitiliginous macule served as control. Lesions were divided into two groups: Group A received combination therapy of daily topical antioxidant plus excimer light, while Group B received only excimer light. Lesions were treated twice a week for a maximum of 24 sessions. Initial fluencies were adjusted individually according to the minimal erythema dose in vitiliginous skin. Efficacy based on repigmentation percentages were blindly evaluated by two independent physicians. Results: Group A lesions showed significant efficacy than group B (p < 0.001), specially on treating UV-sensitive lesions with no side effects. Conclusion: Topical antioxidant and excimer light represents a valuable, effective therapy for localized vitiligo.

Topical tacalcitol and 308-nm monochromatic excimer light: a synergistic combination for the treatment of vitiligo

BACKGROUND/PURPOSE: To study and compare the efficacy of combined 308-nm monochromatic excimer light (MEL) therapy with tacalcitol vs. that of MEL 308-nm therapy alone in treatment of vitiligo. METHODS: Thirty-eight patients with vitiligo were enrolled in a single-blind, within patient controlled clinical trial. Symmetrical or nearby lesions were randomly applied with either topical tacalcitol cream or vehicle. Each lesion was treated weekly with the 308-nm MEL, for a total of 12 sessions. Patients were examined at monthly intervals. The mean number of sessions and the cumulative dosage for initial repigmentation were calculated. RESULT: Thirty-five patients were evaluated. Treatment with tacalcitol and MEL resulted in higher percentages for excellent repigmentation (25.7%) compared with vehicle and MEL (5.7%) (P<0.05). Percentages for total response were 71.4% and 60%, respectively (P>0.05). The mean+/-SEM cumulative dose and number of excimer light exposures for initial repigmentation were, respectively, 3.93+/-0.59 J/cm2 and 4.52+/-0.49 at the tacalcitol side, and, respectively, 4.99+/-0.68 J/cm2 and 5.3+/-0.52 at the vehicle side (P<0.05). CONCLUSION: Our results have shown that concurrent topical tacalcitol potentiates the efficacy of the 308-nm MEL in the treatment of vitiligo, and that this combination achieves earlier pigmentation with a lower total dosage.

The 308-nm excimer laser: a promising device for the treatment of childhood vitiligo

Background: Numerous modalities have been used to treat vitiligo in children. Up to now, phototherapy and topical corticosteroids are the most commonly used treatments for adult vitiligo but studies evaluating the efficacy of these treatments in the pediatric population remain insufficient. Objective: This study was a retrospective review to evaluate the efficacy and safety of 308‐nm excimer laser treatment in 30 childhood vitiligo patients. Methods: Thirty vitiligo patients with 40 vitiligo patches were evaluated after the cessation of 308‐nm excimer laser treatment. Results: Seventeen patients (56.7%) with 20 patches (50%) achieved an acceptable degree (>50%) of repigmentation at the end of the treatment, with five patches (12.5%) showing >75% of repigmentation. The treatment response showed anatomical preferences, favoring the face, neck and trunk. However, the treatment response did not correlate to the cumulative dose or duration of treatment. Side effects occurred in nine patients, but were transient and minimal. Conclusion: The results of this study shows that the 308‐nm excimer laser can be an effective and promising device for the treatment of various vitiligo types, other than generalized, in childhood.
