Abstract
Dupilumab, a monoclonal antibody targeting interleukin-4 antibody, is approved for use in many type 2 inflammatory diseases, including atopic dermatitis. It is generally well tolerated with no need of routine laboratory monitoring. However, several adverse events have been reported during real-world practice and in pivotal trials. We conducted a systematic literature research of the PubMed, Medline, and Embase databases to identify articles recording the clinical manifestation and potential pathogenesis of these adverse events with interests (AEIs) to dermatologists. In total, 547 cases from 134 studies have developed 39 AEIs 1 day to 2.5 years after dupilumab treatment. The most common AEIs are facial and neck dermatitis (299 cases), psoriasis (70 cases), arthralgia (56 cases), alopecia (21 cases), cutaneous T cell lymphoma (19 cases), severe ocular diseases (19 cases), and drug eruption (6 cases). Most of the AEIs recorded in this review resolved or improved after dupilumab discontinuation or the addition of another treatment, whereas 3 of the cases died of severe AEI. The potential pathogenesis included T help type 1 (Th1)/T help type 2 (Th2) imbalance, Th2/T help type 17 (Th17) imbalance, immune reconstitution, hypersensitivity reaction, transient hypereosinophilia related, and Th1 suppression. Clinicians should be alert of these AEIs for timely diagnosis and appropriate treatment.
