Dupilumab effectiveness for the treatment of patients with concomitant atopic dermatitis and chronic rhinosinusitis with nasal polyposis.

Abstract

Dupilumab is a fully human monoclonal antibody targeting interleukin (IL) 4 and IL13 pathways. We performed a retrospective observational study to evaluate the efficacy of dupilumab for the treatment of adult patients referred to our department, from January 2019 to May 2021, with a diagnosis of moderate to severe atopic dermatitis (AD) and concomitant chronic rhinosinusitis with nasal polyps (CRSwNP), with a clinical indication for dupilumab treatment. Skin disease activity was assessed using EASI, Numerical Rating Scale (NRS) for pruritus (P-NRS) and sleep (S-NRS), and Dermatology Life Quality Index (DLQI). The CRSwNP activity was evaluated using 22-item Sino-Nasal Outcome Test (SNOT-22), endoscopic nasal polyp score (ENPS), nasal congestion or obstruction score (scale 0-3), loss-of-smell score (scale 0-3), and rhinosinusitis disease severity (visual analog scale 0-10 cm). A significant improvement of all the score values was recorded assessing patients at baseline, week (W)16, and W24. In particular, concerning the CRSwNP, a reduction of ENPS score (baseline: 4.9 ± 1.85; W16: 2.49 ± 1.42, p < 0.01; W24: 1.68 ± 1.25, p < 0.01) and SNOT-22 (baseline: 35.9 ± 19.11; W16: 12.85 ± 6.31, p < 0.01; W24: 10.71 ± 7.29, p < 0.01) was observed. Furthermore, dupilumab is a labeled drug for the treatment of both AD and CRSwNP. The use of a single drug to obtain the improvement up to the near remission of AD and CRSwNP increases not only patient's compliance with the treatment, but also the benefits in terms of health cost related to these chronic diseases.
