Abstract

Introduction: Alopecia areata (AA) is a non-scarring autoimmune disease characterized by patchy hair loss. The aim of this study was to validate a novel trichoscopic scoring tool, the Severity TRichoscopy Index for Alopecia Areata (STRIAA), for rapid assessment of AA severity.

Methods: Anonymized images from 340 patients were scored by two independent raters who analyzed four scalp areas (vertex, occipital, and left and right parietal) for trichoscopic signs: black dots, yellow dots, exclamation mark hairs, broken hairs, and short vellus hairs. Scores (0-3) were assigned according to the number of trichoscopic signs per area, resulting in a total STRIAA score out of 60.

Results: STRIAA showed high interrater reliability (Cronbach's alpha 0.99) and significant correlation with the Severity of Alopecia Tool (SALT) score (p < 0.001). Yellow and black dots were significantly associated with the SALT score.

Conclusions: The STRIAA provides a rapid and comprehensive assessment of AA severity, complementing current assessment tools in clinical practice.

STRIAA（严重性毛发镜指数斑秃）：一种评估斑秃的新型毛发镜工具的验证。

简介：斑秃（AA）是一种以斑状脱发为特征的非瘢痕性自身免疫性疾病。本研究的目的是验证一种新的毛发镜评分工具——斑秃严重程度毛发镜指数（STRIAA），用于快速评估斑秃严重程度。方法：来自340名患者的匿名图像由两名独立评分者评分，他们分析了四个头皮区域（顶点、枕部、左右顶叶）的毛发镜征象：黑点、黄点、感叹号毛、断毛和短绒毛。评分（0-3）根据每个区域的trichoscopic征象的数量进行分配，得出STRIAA总分60分。结果：STRIAA具有较高的判据信度（Cronbach's alpha 0.99），且与脱发严重程度工具（SALT）评分具有显著相关性(p)。结论：STRIAA提供了一种快速、全面的脱发严重程度评估方法，补充了临床实践中现有的评估工具。

期刊介绍： Dermatology and Therapy is an international, open access, peer-reviewed, rapid publication journal (peer review in 2 weeks, published 3–4 weeks from acceptance). The journal is dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of dermatological therapies. Studies relating to diagnosis, pharmacoeconomics, public health and epidemiology, quality of life, and patient care, management, and education are also encouraged. Areas of focus include, but are not limited to all clinical aspects of dermatology, such as skin pharmacology; skin development and aging; prevention, diagnosis, and management of skin disorders and melanomas; research into dermal structures and pathology; and all areas of aesthetic dermatology, including skin maintenance, dermatological surgery, and lasers. The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports/case series, trial protocols, and short communications. Dermatology and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an International and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of quality research, which may be considered of insufficient interest by other journals. The journal appeals to a global audience and receives submissions from all over the world.
