title: Evidence-based, non-surgical treatments for vitiligo: a review.
abstract: Vitiligo is an acquired pigmentary disorder characterized by depigmented macules and patches secondary to the loss of functional melanocytes. It is a chronic disease that affects between 0.1% and 2% of the general population, affecting both sexes and all races. The appearance and the unpredictable course are psychologically and socially devastating. The success of current therapeutic options is limited. The objective of this review was to assess non-surgical treatments of vitiligo and to determine if comparing these studies can lead to (1) practical applications in the clinical setting and (2) recommendations for future research including study design and topics to be investigated further. Combination therapies were found to be more effective than monotherapy, and most combinations included a form of phototherapy, of which narrow-band-UVB was found to be most effective with the least adverse effects. Topical treatment with corticosteroids, immunomodulators, vitamin D analogs, and psoralens had mixed outcomes. Oral therapies including antioxidants were helpful adjuvants to treatment. Studies lacked consistent design, mechanism of disease assessment, and long-term follow-up. Sample size was also frequently limited. This review found that while several non-surgical therapies exist for the treatment of vitiligo, their usefulness, especially in the long term, is not well understood. Those studies that were able to elicit repigmentation often lacked an assessment on quality of life and/or patient satisfaction. More standardized methods of study design and assessment are needed to compare outcomes and make definitive conclusions on treatment effectiveness.
