Advances in the study and application of digital technology in the clinical practice of atopic dermatitis

Atopic dermatitis (AD) is a complex, chronic inflammatory skin disease that requires individualised and precise diagnostic and treatment strategies. In recent years, digital technologies have opened new avenues for its diagnosis and treatment. This article descriptively reviews the progress of digital technologies in AD from four aspects: diagnosis, treatment, care, and research and development. Artificial intelligence (AI)-assisted analysis of skin lesion images improves diagnostic objectivity, while skin ultrasound quantifies inflammatory indicators. Telemedicine platforms optimise treatment plans by integrating real-time monitoring data, and smart devices enhance skin barrier management. Multi-omics combined with AI-assisted drug design accelerates the development of targeted therapies. Despite challenges such as data privacy and technical standardisation, digital technologies are establishing a closed-loop system of "monitoring-intervention-feedback," driving a paradigm shift in AD diagnosis and treatment. Future efforts should focus on deepening technology integration, interdisciplinary collaboration and real-world data application to achieve full-cycle individualised management.
