Abstract
BACKGROUND: Vitiligo-affected individuals, especially patients with darker skin tones, can suffer from negative psychosocial impacts due to unpredictable development of the condition and perceived cosmetic concerns. However, given that spontaneous repigmentation can be gained in vitiligo, many patients ask for treatment due to these cosmetic concerns. In the literature, only a few studies have been documented focusing on the outcome of various treatment modalities for vitiligo. OBJECTIVE: This article highlights the retrospective response of various treatment modalities in Indian patients with vitiligo. METHODS: A retrospective chart review was performed from July 2017 to August 2018 at our private dermatology clinic. A total of 3,000 patients were enrolled in this observational study. Patient characteristics and details of phototherapy (psoralen and ultraviolet A, narrow-band ultraviolet B, excimer laser) were noted as per a predefined format. The clinical response was evaluated as a marked response, defined as repigmentation in more than 75% of the initial lesional area. RESULTS: Of those included in this retrospective analysis, 1,996 patients received phototherapy and 1,004 patients were treated with topical monotherapy. Patients treated with phototherapy only and those treated with a combination of phototherapy and topical agents showed significantly higher clinical response rates relative to patients treated with topical monotherapy only (marked response rate: 47.8% vs. 8.7%; P<0.001 and 23.4% vs. 8.7%; P<0.001). Disease subtype predominately affected the treatment response. CONCLUSION: In Indian patients with vitiligo, phototherapy appears to be an effective treatment option for both focal and vitiligo vulgaris. Due to its reliability and minimal side effects, it can be considered a preferable treatment modality for vitiligo.
