Official Title: Comparison of the Efficacy of Micro-holes vs. Laser-assisted Dermabrasion, for Repigmenting in Vitiligo Skin
Brief Summary:
Principal objective: To compare the efficacy of laser-assisted dermabrasion + autologous epidermal cells suspension grafting versus dermabrasion using micro-needling technique + autologous epidermal cells suspension grafting and dermabrasion using micro-needling technique + placebo suspension grafting in stable vitiligo.
A total of 10 patients with stable non-segmental vitiligo will be included in the ITT population.
In each patient, three separate test areas will be selected in the same part of the body.
One area will be pre-treated with dermaroller and receive the hyaluronic acid suspension alone and the two others will receive the epidermal cell suspension in hyaluronic acid after pre-treatment either with dermaroller or laser-assisted dermabrasion, each patient being his own control.
Targeted phototherapy with excimer lamp (308 nMm) will be applied on all test areas 1 week after cell grafting.
Detailed Summary:
Condition Stable lesion of Vitiligo of adulthood
Background Laser-assisted dermabrasion is the gold standard for preparing the grafting bed of epidermal suspension but it requires a technical platform and a trained physician. Side effects are not uncommon. We have demonstrated in an ex vivo study that micro-needles create holes in the epidermis allowing cells to reach the lower layers of the epidermis. We hypothesize that the use of micro-needles could be an effective and easy technique for preparing the grafting bed for epidermal suspensions.
Objectives Principal objective: To compare the efficacy of laser-assisted dermabrasion + autologous epidermal cells suspension grafting versus dermabrasion using micro-needling technique + autologous epidermal cells suspension grafting and dermabrasion using micro-needling technique + placebo suspension grafting in stable vitiligo.
The secondary objectives are
- To evaluate and compare the tolerability of the distinct procedures
- To evaluate the global satisfaction of patient and the willingness to reproduce the procedure for treating other areas
- To evaluate the contrast between treated skin and perilesional area
Methods Prospective, multicentre, randomized, controlled, blind assessor trial.
Inclusion criteria
- Men and women aged over 18 years old with a diagnosis of non-segmental lesions that has been stable over three months
- The minimum distance between the normal pig
