Epidermal grafting in vitiligo: influence of age, site of lesion, and type of disease on outcome

J Am Acad Dermatol. 2003 Jul;49(1):99-104. doi: 10.1067/mjd.2003.415.

Abstract

Background: The success of suction blister epidermal grafting may be influenced by various factors, all of which have not been studied to date.

Objective: We sought to determine the influence of age of the patient, site of vitiligo patch, and type of disease on the outcome of the procedure in our patients and in the cumulative data derived from literature analysis.

Methods: This was a retrospective, uncontrolled case series and literature review of suction blister epidermal grafting in patients with stable and recalcitrant vitiligo. All published studies of suction blister epidermal grafting in vitiligo involving 10 or more patients were included in the literature analysis.

Results: The procedure was performed in 143 patients. However, sufficient length (6 postoperative months) of follow-up was available in only 117 patients, and only these patients were included for analysis. Only limited information was available about various factors in the majority of published studies. The success rates for generalized and segmental/focal disease in this study were 53% (confidence interval [CI] 42-64) and 91% (CI 81-100), respectively (P <.001), and in the literature, 61% (CI 46-76) and 88% (CI 82-94), respectively (P <.01). The success rates in patients aged < 20 years and >or= 20 years in this study were 82% (CI 67-97) and 58% (CI 48-68), respectively (P <.05), and in the literature, 100% and 66% (CI 56-76), respectively (P <.05). There was no significant difference in the success rates achieved on different body sites in this study and in the screened literature. Among adverse reactions, hyperpigmentation in 32% (CI 24-40) and 17% (CI 14-20), infection in 6% (CI 2-10) and 0%, and contact dermatitis in 1% (CI 0-3) and 1% (CI 0-2) of patients were observed in this study and in the analyzed literature, respectively.

Conclusions: The results were significantly better in segmental/focal vitiligo than in the generalized type, and in individuals < 20 years of age. However, unlike in medical therapies, localization of the vitiligo patch did not influence the treatment outcome significantly.
