Abstract：
Precise evaluation of repigmentation in vitiligo patients is crucial for monitoring treatment efficacy and enhancing patient satisfaction. This study aimed to develop a computer-aided system for assessing repigmentation rates in vitiligo patients, providing valuable insights for clinical practice. A retrospective study was conducted at the Dermatology Department of Shenzhen People\'s Hospital between June 2019 and November 2022. Pre- and post-treatment images of vitiligo lesions under Wood\'s lamp were collected, involving 833 participants stratified by sex, age, and pigmentation patterns. Our results demonstrated that the marginal pigmentation pattern exhibited a higher repigmentation rate of 72% compared with the central non-follicular pattern at 45%. Males had a slightly higher average repigmentation rate of 0.37 in comparison to females at 0.33. Among age groups, individuals aged 0-20 years showed the highest average repigmentation rate at 0.41, while the oldest age group (61-80 years) displayed the lowest rate at 0.25. Analysis of multiple visits identified the marginal pattern as the most prevalent (60%), with a mean repigmentation rate of 40%. This study introduced a computational system for evaluating vitiligo repigmentation rates, enhancing our comprehension of patient responses, and ultimately contributing to enhanced clinical care.
摘要：
准确评估白癜风患者的色素沉着对于监测治疗效果和提高患者满意度至关重要。这项研究旨在开发一种计算机辅助系统，用于评估白癜风患者的色素沉着率。为临床实践提供有价值的见解。回顾性研究于2019年6月至2022年11月在深圳市人民医院皮肤科进行。收集伍德灯下白癜风病变的治疗前后图像，涉及833名按性别分层的参与者，年龄,和色素沉着模式。我们的结果表明，与45％的“中央非卵泡”模式相比，“边缘”色素沉着模式表现出更高的72％的再色素沉着率。与0.33的雌性相比，雄性的平均色素沉着率稍高，为0.37。在年龄组中，0-20岁的个体显示出最高的平均再色素沉着率，为0.41，而年龄最大的年龄组（61-80岁）显示出最低的比率，为0.25。对多次访问的分析确定“边缘”模式是最普遍的(60%)，平均再色素沉着率为40%。这项研究引入了一种评估白癜风色素沉着率的计算系统，增强我们对病人反应的理解，最终有助于加强临床护理。
