Canadian Consensus Guidelines for the Management of Vitiligo.

INTRODUCTION

Vitiligo remains a highly burdensome disease associated with significant autoimmune and psychosocial comorbidities. Although the therapeutic landscape has long been dominated by off-label therapy, new treatments are emerging. Limited guidance on how to safely and effectively utilize available therapies poses challenges for healthcare providers. Herein, we provide generally accepted principles, consensus recommendations, and a treatment algorithm for the management of vitiligo, as developed by a panel of ten Canadian dermatologists with expertise in managing vitiligo.

METHODS

The three-phase process consisted of identifying themes and research questions; conducting a systematic literature review; and discussing/voting on generally accepted principles, consensus statements, and a treatment algorithm using an iterative consensus process.

RESULTS

Experts agreed to 27 generally accepted principles, ten consensus statements, and a treatment algorithm. Education about vitiligo pathogenesis and repigmentation biology can help patients, caregivers, and healthcare providers set realistic expectations for treatment. Treatment should focus on repigmentation or stabilizing progression, rather than on depigmentation. Topical therapies include topical corticosteroids, topical calcineurin inhibitors, and the topical Janus kinase inhibitor ruxolitinib cream. Phototherapy, such as narrow-band ultraviolet B and excimer laser/lamp, can be used as monotherapy or in combination with other treatments. Off-label systemic therapies may be appropriate for patients with unstable or rapidly progressing disease. Surgical therapy may be suitable for patients with localized or stable recalcitrant disease. Maintenance therapy may help mitigate the risk of disease relapse.

CONCLUSION

Improved clarity around the benefits, risks, and limitations of available therapies has supported the development of robust guidelines and a treatment algorithm for vitiligo. Disease stabilization and repigmentation are goals that can largely be achieved, particularly when patients share a mutual understanding of vitiligo and its treatment options.
