A Systemic Review of Dupilumab Efficacy and Safety by Phenotypic Variations of Atopic Dermatitis

Abstract

Background: The Atopic Dermatitis (AD) is a chronic, pruritus- inflammatory TH2dominant skin disorder characterized by a reaction with complex immunopathogenesis. Dupilumab’s effectiveness and safety profile by phenotypic variations of atopic dermatitis the treatment of atopic dermatitis has been investigated in a variety of large clinical trials in atopic dermatitis for more than 10 years. The goal of the current systematic review was to determine the effectiveness and protection of dupilumab through phenotypic differences in atopic dermatitis. Methods: We systematically searched PubMed, MEDLINE, EMBASE and Google scholar databases to find appropriate articles published between last ten years related to dupilumab efficacy and safety by phenotypic variations of atopic dermatitis with the appropriate key terms (MeSH) including “dupilumab”, “atopic dermatitis”, “eczema”, “phenotypic variations” “phenotypes” etc. Results: Seven studies were included in the current review, which met the inclusion & exclusion criteria of the current study. All the included studies in this review demonstrated that the dupilumab significantly treated the various phenotypes of AD, with the improvement of EASI and DLQI scores. The most commonly occurred side effect during the treatment of duplimab was allergic conjunctivitis followed by allergic rhinitis and asthma. Most of the included studies demonstrated that the dupilumab has been shown to rapidly improving signs and symptoms in the treatment of extreme AD. Conclusion: Dupilumab was first prescribed for adults with atopic dermatitis and has been generally approved since 2018 for adult patients with moderate to extreme atopic dermatitis. The IL-4 and IL-13 cytokines in atopic dermatitis modulate the epidermal barrier and inhibit the production of antimicrobial peptides. Dupilumab’s efficacy and safety profile in the treatment of atopic dermatitis has been investigated in a number of major clinical trials. This current systematic review provides an evidence-based report on dupilumab efficacy and safety by different phenotypic variations of atopic dermatitis, which will help to clinicians for better understanding of the mechanism of dupilumab against AD phenotypes.
