Assessment of Patient-Reported Outcomes at 48 Months of Treatment with Dupilumab for Severe Atopic Dermatitis: A Single-Center Real-Life Experience with 126 Patients

Background: The main objective was to analyze patient-reported outcomes (PRO) trends over a four-year period in severe atopic dermatitis (AD) patients treated with dupilumab. Methods: data from 126 severe patients receiving dupilumab for at least 48 months were collected. The clinical scores assessed included the Eczema Area and Severity Index (EASI), Pruritus Numerical Rating Scale (NRS), Sleep NRS, Patient-Oriented Eczema Measure (POEM), Dermatology Life Quality Index (DLQI), and Atopic Dermatitis Control Tool (ADCT). Results: the study compellingly demonstrates dupilumab's effectiveness in reducing EASI and improving PROs, with sustained enhancements observed beyond the initial twelve months of treatment. Univariate and multivariate regression analyses show that baseline factors do not significantly increase the risk of adverse outcomes related to Pruritus NRS, POEM, or ADCT at T48. The robust correlation between ADCT and other PROs suggests closely aligned changes. Conclusion: Dupilumab's benefits endure beyond the first year, emphasizing its long-term efficacy, and consistently improves AD outcomes regardless of individual characteristics or clinical variables. ADCT appears to be a practical and versatile tool for the streamlined assessment of AD treatment outcomes.
