“…Results of clinical trials revealed that dupilumab is associated with increased incidence of conjunctivitis only in patients with AD but not in those with asthma, chronic rhinosinusitis with nasal polyps, or eosinophilic esophagitis ( Akinlade et al., 2019 ; Bachert et al., 2016 ; Blauvelt et al., 2017 ; Castro et al., 2018 ; de Bruin-Weller et al., 2018b ; Hirano et al., 2020 ; Rabe et al., 2018 ; Simpson et al., 2020 ; Thaçi et al., 2016 ; Wenzel et al., 2016 , 2013 ). In the real world, dupilumab-associated conjunctivitis has also been reported ( Achten et al., 2021 ; Armario-Hita et al., 2019 ; de Wijs et al., 2020a ; Faiz et al., 2019 ; Fargnoli et al., 2019 ; Jo et al., 2020a ; Liberman et al., 2020 ; Nahum et al., 2020 ; Nettis et al., 2020a ; Ribero et al., 2020 ; Ruiz-Villaverde et al., 2019 ; Touhouche et al., 2021 ; Uchida et al., 2020 ; Wang et al., 2020 ). The incidence of conjunctivitis seems to be higher in the real world (up to 62%) than in clinical trials (8.6–22.1%).…”
