Summary

Background: New light shed on the cholinergic aspects of vitiligo pathophysiology. It was found that acetylcholine concentration increased with a significantly reduced expression of acetylcholinesterase in vitiliginous patches that return to normal up on repigmentation.

Objective: The investigators will undertook this controlled, prospective pilot study to evaluate the efficacy and safety of botulinum toxin A in patients with localized vitiligo.

Methods: 10 patients with focal or segmental vitiligo will be recruited. For each patient with focal vitiligo, one or two vitiliginous patches will be treated. The other patches will be used as control. For each patient with segmental vitiligo, half of the lesion will be treated. The other half will be used as a control. Botulinum toxin will be injected. The response will be analyzed at the initial visit, two weeks and at two and six months after therapy.

Conditions

  • Vitiligo

Interventions

DRUG

Botulinum toxin A

Dilution of 1 ml of unpreserved saline per 100 U vial of BOTOX (Allergen pharmaceuticals, Irvine, CA). 2 units were injected intradermally every 1 cm2 with a 1ml syringe and 30 gauge needle. For each patient with focal vitiligo, one vitiliginous patch - or two patches from different sites- will be treated. The other patches from the contra lateral site will be left untreated and used as control at the follow-up visit. For each patient with segmental vitiligo, half of the lesion will treated. The other half will be left untreated and used as a control at the follow-up visit.
