Comparison between the efficacy of microneedling combined with 5-fluorouracil vs microneedling with tacrolimus in the treatment of vitiligo

Summary

Background

Several treatment modalities had been used for the treatment of vitiligo, but the optimal treatment has not yet been identified.

Objectives

To study the efficacy of microneedling with 5-flurouracil vs its efficacy with tacrolimus in the treatment of vitiligo.

Patients and methods

Twenty-five patients with vitiligo were subjected to microneedling of 2 patches of vitiligo with dermapen, then application of 5-fluorouracil to 1 patch and tacrolimus on the other patch. This procedure was repeated every 2 weeks for every patient for maximum 6 months (12 sessions). The patients were followed up for 3 months after the last session.

Results

The overall repigmentation was significantly higher in 5-fluorouracil-treated patches compared with tacrolimus. Excellent improvement occurred in 48% of 5- flurouracil-treated patches while only in 16% of tacrolimus-treated patches. In the acral parts, 40% of the patches treated with 5-fluorouracil achieved excellent improvement (repigmentation >75%), while no patch in the acral parts achieved excellent improvement with tacrolimus. However, there was significant difference between the 2 drugs,regarding inflammation, ulceration, and hyperpigmentation which occurred with 5-fluorouracil.

Conclusion

Microneedling combined with 5-fluorouracil or tacrolimus is safe and effective treatment of vitiligo. However, 5-fluorouracil achieved a greater percentage of repigmentation than tacrolimus particularly in the acral parts.
