Abstract

BACKGROUND: The clinical features of adult-onset atopic dermatitis (AD) are heterogeneous and the diagnosis can be a challenge. A new biologic drug (dupilumab) has been approved for moderate to severe AD in adult patients. The efficacy and safety have been demonstrated in clinical trials, but these studies do not reflect conditions in daily practice and do not consider the different clinical manifestations of AD.

OBJECTIVES: Analyzing the dupilumab activity in a real-world setting and comparing its efficacy on different AD phenotypes.

METHODS: We retrospectively evaluated 221 AD patients treated with dupilumab, stratified into six clinical phenotypes: classic, generalized eczema inflammatory and lichenoid patterns, prurigo, nummular eczema, and erythroderma. At baseline and at weeks 4, 16, and 52, the disease severity was assessed through the Eczema Area and Severity Index (EASI) and the quality of life was assessed through the Dermatology Life Quality Index (DLQI) questionnaire, Peak Pruritus Numerical Rating Scale (itch NRS), and Peak Sleep NRS.

RESULTS: We found a significant improvement after 16 weeks of treatment (p < 0.0001) in all six phenotypes for all the assessed scores mentioned above, persisting up to week 52. The best improvement was seen in the more severe phenotypes, particularly the erythrodermic one.

CONCLUSIONS: The present study confirmed the efficacy and safety of dupilumab in the treatment of severe AD. Its strength was in the stratification of AD patients in six different phenotypes based on their clinical presentation, all of whom markedly improved in terms of both clinically evident and reported symptoms, as well as their quality of life.
