Intradermal injection of Fluorouracil versus triamcinolone in localized vitiligo treatment

Summary

Background

Vitiligo is an autoimmune disease with a prevalence of 1.22% in Egypt. Intralesional steroids use in localized vitiligo treatment still a matter of debate. Fluorouracil was tried in vitiligo treatment after lesion dermabrasion, ablative laser, or micro‐needling. The study aimed to compare the efficacy of intradermal fluorouracil and triamcinolone acetonide without any adjuvant therapy in localized vitiligo treatment.

Patients and methods

Sixty patients with localized non‐segmental stable vitiligo were assigned randomly and equally into groups. Patients subjected to intradermal injection of either fluorouracil (50 mg/mL), triamcinolone acetonide (3 mg/mL) or an equal mixture of both drugs. All patients had four treatment sessions every 2 weeks were followed up for 6 months.

Results

Intradermal fluorouracil showed the best overall improvement (median 52.27, IQR 36.25‐68.18) when compared with triamcinolone (median 13.86, IQR 3.83‐33.32) and the drug mixture (median 17.15, IQR 7.48‐41.67). During follow‐up, the vitiliginous patches continued to repigment for 6 months in fluorouracil and the drug mixture groups. The improvement stopped 1 month after the last session in the triamcinolone group.

Conclusion

The intradermal fluorouracil injection is an effective treatment of localized vitiligo. The intradermal steroid has a short‐acting therapeutic effect, but the mixture of drugs added no therapeutic effect.
