A real-world study in Brazilian patients with atopic dermatitis treated with dupilumab who previously received methotrexate and cyclosporine

Abstract

Introduction: Atopic Dermatitis (AD) is a chronic inflammatory skin disease that significantly impacts patients´ quality of life. Dupilumab was Brazil´s first biologic approved to treat moderate-to-severe AD. We aimed to assess the effectiveness and safety of dupilumab in a real-life setting for 16 weeks. Methods: Fourteen patients were evaluated at weeks 0, 4, and 16 after the first dupilumab shot. At each visit, disease activity and severity, itching intensity, and impact on quality of life were measured using the EASI (Eczema Area and Severity Index), IGA (Investigator’s Global Assessment), SCORAD (Scoring Atopic Dermatitis), NRS (Numeric Rating Scale for itching), and DLQI (Dermatology Life Quality Index). Results: Clinical improvement observed was significant, with variation in all scores used in the study sample during the first 16 weeks of treatment (p < 0.0001). Conclusion: Dupilumab was effective and safe in our patients with moderate-to-severe AD.
