AI-Summary

What this Trial Is About

This research project investigates the clinical and genetic associations of Actinic Prurigo (AP) in the Thai population. As a rare chronic photodermatosis, AP has been observed to occur more frequently in individuals with certain genetic predispositions, particularly specific Human Leukocyte Antigen (HLA) types. Previous studies have suggested variations in clinical presentation and HLA allele distributions between Asian and Western populations. The primary aim is to explore the relationship between clinical manifestations of AP and genetic profiles, including HLA typing, among Thai individuals. Additionally, the study seeks to examine whether different HLA types are associated with varying responses to treatment. The study design is a cross-sectional comparative study, involving both AP patients and age-matched healthy controls. Given the rarity of the condition, patient recruitment will be conducted across four collaborating institutions: King Chulalongkorn Memorial Hospital Siriraj Hospital Institute of Dermatology
