Microneedling in Combination with Topical Pimecrolimus 1% versus Topical Pimecrolimus 1% for the Treatment of Refractory Stable Vitiligo: A Randomized Clinical Trial

Abstract

Objective. Vitiligo is a common, autoimmune disease that results in the destruction of the melanocytes and manifests as depigmented macules on various areas of the skin. Numerous treatment options have been proposed for vitiligo. The purpose of this study was to compare the efficacy of microneedling plus topical pimecrolimus 1% versus the sole use of topical pimecrolimus 1% for the treatment of vitiligo. Methods. This clinical trial was conducted on 30 skin lesions on 15 Al-Zahra hospital patients. Each patient had two similar lesions in the limb area, and each lesion was considered a separate treatment group. The left or right side of the patient’s lesion was randomly assigned to receive microneedling plus topical pimecrolimus for three months, while the other side received only topical pimecrolimus 1%. As part of the follow-up, digital photography was taken at the baseline and biweekly for three months after treatment and six months’ follow-up. The following methods were used to evaluate the results: DLQI questionnaires, patient satisfaction questionnaires, and two independent dermatologists comparing the improvement rate for each group. Results. Topical pimecrolimus 1% treatment led to unsatisfactory results, whereas the combination of microneedling and topical pimecrolimus1% treatment produced a more favorable overall outcome ( $P<0.001$ ). Conclusion. This study established that combination therapy results in more significant patient improvement. Additionally, one patient experienced mild skin irritation as a side effect of topical pimecrolimus.
