New โคStudy Identifies Key Factors Increasing Atopic Dermatitis Relapse Risk Afterโ Dupilumab Treatment Halt
A recent retrospective cohort analysis hasโค pinpointed several factors associated with increased risk โof โatopic dermatitis (AD) recurrence following discontinuationโ of dupilumab, a biologic therapy. the study, published in Frontiers in Medicine in 2025, foundโข that male sex (HR, 2.34; 95% CI, 1.14-4.78; P = .02) and a history of allergic rhinitis (HR, 2.61; 95% CI, 1.37-5.00; P = .004)โ were significantly linked to reduced drug survival during dupilumab treatment.
These findings align with previous research demonstrating โmale sex (โข P = .002) and high BMI (P < .000) as potential determinants of AD severity. โConversely, other studies have indicated that female gender and a BMI below 24 kg/m2 โข may correlateโค with improved responses to dupilumab.3-5
Investigators emphasized โขthe importance of early intervention upon AD relapse and comprehensiveโค management, including reassessment, potential dupilumab reinitiation, and โฃconsideration of option treatment strategies. Notably, the study demonstrated that dupilumab remained effective when reintroduced, benefiting both youngerโ and older patients-reflecting a real-world โฃpopulation. Researchers believe theโ data highlightโ “modifiable factors leading toโ [atopic dermatitis] relapse and provide insight into the risk profiles โassociated with relapse at different stagesโ of โขdisease.”
