Abstract

Background: Dupilumab effectively treats atopic dermatitis (AD); however, its role in halting the atopic march remains uncertain. Objective: To investigate dupilumab's effect on atopic march in pediatric AD patients versus conventional immunomodulators. Methods: This retrospective cohort study utilized data from the TriNetX US Collaborative Network (2011-2024). Pediatric AD patients (≤18 years) were categorized into DUPI-cohort (newly prescribed dupilumab) or CONV-cohort (prescribed conventional immunomodulators without dupilumab). After 1:1 propensity-score matching, we analyzed atopic march progression, defined by the incident asthma or allergic rhinitis (AR). Cumulative incidence was plotted using Kaplan-Meier, with risk assessment via Cox regression. Results: The study included 2192 patients in each cohort. The 3-year cumulative incidence of atopic march progression was lower in the DUPI-cohort than the CONV-cohort (20.09% vs 27.22%; P <.001). The DUPI-cohort demonstrated significant risk reduction in atopic march progression (hazard ratio [HR] 0.68, 95% CI 0.55-0.83), individual asthma (HR 0.60, 0.45-0.81), and individual AR (HR 0.69, 0.54-0.88). Younger patients on dupilumab exhibited a greater risk reduction for atopic march progression and individual asthma, contrasting with the opposite age-related pattern for individual AR. Limitations: Observational study. Conclusion: Among pediatric AD patients, dupilumab was associated with reduced risk of atopic march progression compared with conventional therapies.
