Global Real-World Study of Disease Impact in Adolescents and Adults with Moderate to Severe Alopecia Areata, Non-Segmental Vitiligo, or Hidradenitis Suppurativa

What this Trial Is About

Researchers are studying the impact and burden of three skin conditions moderate or severe alopecia areata, non-segmental vitiligo, and moderate to severe hidradenitis suppurativa. The study includes adolescents and adults and aims to understand how these conditions affect quality of life and daily functioning in a large global population. This is an observational study where participants with each condition will have a single visit for data collection following routine clinical practice. No experimental treatments are given instead, the study gathers information during this one visit to assess disease characteristics and impact. During the visit, participants will complete questionnaires and clinical assessments specific to their condition. These include tools measuring symptom impact, hair loss severity, skin depigmentation, and quality of life related to each disease. This helps researchers better understand the real-world burden of these conditions. Participation involves only this one visit, with no long-term follow-up or additional procedures.
