Background: The current therapies for vitiligo require long duration with often disappointing outcomes. 5‐Fluorouracil (5‐FU) is a chemotherapeutic agent approved for topical use in the treatment of several dermatologic conditions. Matrix metalloproteinase 2 (MMP2) is synthesized by keratinocytes during the epidermal remodeling process and has been found to help in melanocyte migration. Aim: To investigate the efficacy and safety of flexible microneedling followed by application of 5‐FU in vitiligo treatment and to evaluate the immunohistochemical expression of MMP2 in involved skin in vitiligo patients before and after treatment. Methods: Twenty patients presented with vitiligo were planned to receive one session every 2 weeks for 12 weeks of microneedling followed by 5‐FU application. Clinical response to therapy was evaluated by VASI score. Pre‐ and post‐treatment biopsies were taken from vitiliginous patches for MMP2 immunostaining. Results: Fifteen patients (75%) responded to therapy with observed side effects such as pain, erythema, and hyperpigmentation of margins. The clinical response was more in young patients and those who have short disease duration. MMP2 was significantly increased in post‐treatment biopsy compared with the pretreatment one. Conclusions: 5‐Fluorouracil application after microneedling is effective in the treatment of vitiligo with 75% response, 60% patient satisfaction, and tolerable side effects. The improvement in vitiligo patients by microneedling and 5‐fluorouracil could be due to upregulation of MMP2 in affected vitiligo specimens. [ABSTRACT FROM AUTHOR] |
