Atopic Dermatitis Across the Lifespan: Understanding, Measuring and Minimizing Cumulative Life Course Impairment

Atopic dermatitis (AD) presents a multidimensional burden, often beginning in infancy and accumulating over time. Beyond itch and pain, AD is associated with significant losses of health-related quality of life resulting from sleep disturbance, stigmatization, other atopic diseases and nonatopic comorbidities, among others. These associated conditions affect patients' physical and mental health, development, social interaction and productivity, resulting in what has been termed cumulative life course impairment (CLCI). To alter the trajectory of AD and improve patient outcomes, it is important to identify people at risk of CLCI, measure it in clinical practice and intervene with appropriate treatment. Although a digital, structured questionnaire for adults exists, a separate instrument to assess CLCI in children and adolescents would benefit our understanding of these issues in a patient population in need. This paper discusses the need for such a questionnaire, with the goal of increasing awareness of the lifelong impact of AD among healthcare professionals, caregivers and patients, potentially improving shared decision-making and facilitating conversations about treatment.
