[Dupilumab-related blepharoconjunctivitis: Recommendations of the CEDRE group. Atopic dermatitis, conjunctivitis and dupilumab: Which management approach?]

Dupilumab is a recombinant monoclonal IgG4 type antibody which inhibits IL4 and IL13 signaling. It is indicated in moderate to severe atopic dermatitis (AD) in adults and adolescents over 12 years of age. Its side effects include conjunctivitis and blepharoconjunctivitis, affecting between 4.7% and 28% of patients depending on the study. The incidence of conjunctivitis in patients treated with dupilumab for AD appears to be higher than placebo in clinical studies. This increase was not observed in patients treated with dupilumab for asthma or sinonasal polyposis. The risk factors for conjunctivitis in patients with AD are disease severity, pre-existence of conjunctivitis and low concentrations of dupilumab, but the pathophysiology of this disease is poorly understood. A literature search carried out in April and May 2020 showed an increase in the number of publications on the subject, but there are currently no official joint dermatologist-ophthalmologist recommendations for prevention and management. The objective of this article is to provide an overview of the status of this subject, to address the main questions raised by this type of conjunctivitis and to suggest a course of action for starting and continuing treatment with dupilumab in patients with AD, according to the recommendations of the French Ophthalmologist/Dermatologist group CEDRE.
