Japanese Dermatological Association's Clinical Practice Guidelines for Alopecia Areata 2024: A Complete English Translated Version

Abstract

This is an English-translated version of the Japanese Dermatological Association's clinical practice guidelines for alopecia areata (AA) 2024. It includes the sections of summary, pathogenesis and epidemiology, evaluation and diagnosis, and treatment of AA. Updates based on recent evidence/advances were made in each part. The treatment part contains the statements of recommendation for 25 clinical questions (CQs) with respective recommendation/evidence levels. AA-cube, a graphic illustration conceptualizing the treatment strategy based on individual patients' factors, was newly proposed. Taking into account the recent approval of a JAK inhibitor and a JAK3/TEC family kinase selective inhibitor, a CQ for these modalities was also added. These guidelines aim to support evidence-based management of AA as well as prompt understanding of disease etiopathogenesis.
