Comprehensive survey of vitiligo patients in the northeast of China using a predesigned questionnaire

Abstract

To assess the sociodemographic data and clinical information of outpatients affected by vitiligo in the northeast of China, vitiligo patients or guardians who presented to the clinic were invited to participate in an exploratory questionnaire. The questionnaire consisted of two sections related to vitiligo, including sociodemographic data and clinical information. A total of 983 vitiligo patients answered the questionnaire. The rates of female and male patients were comparable. The investigated patients were mostly young and middle-aged. Most patients suffered from vitiligo in childhood or young adulthood. Vitiligo vulgaris was the most common type of vitiligo in clinic and 53.0% of patients were categorized as body surface area (BSA) of 10% or less. In response to the latest treatment, 43.6% of patients achieved good response (completely stopped or almost disappeared). More patients at active stage showed good response than the patients at stable stage (χ² = 7.866, P < 0.05). Chronic comorbid condition(s) were observed in 12.6% of patients with BSA of more than 10%, whereas those were seen in 6.0% of patients with BSA of 10% or less (χ² = 12.969, P < 0.05). In conclusion, active vitiligo seems to respond better than stable vitiligo and complications with other autoimmune diseases more frequently observed in severe patients than mild patients. The current study presented a comprehensive understanding of vitiligo in the northeast of China.
