Clinical characteristics and management of dupilumab-associated ocular surface disease in Japan.

Dupilumab-associated ocular surface disease (DAOSD) is one of the most common adverse events associated with dupilumab (an anti-interleukin-4-receptor-alpha monoclonal antibody) during the treatment of patients with atopic dermatitis (AD). However, it rarely occurs in patients with bronchial asthma or chronic rhinosinusitis with nasal polyps. Adequate understanding of DAOSD is important for proper diagnosis and appropriate ophthalmic intervention. The aim of this review was to summarize and discuss the clinical characteristics and management of DAOSD in Japan. The pathogenesis of DAOSD can be explained by the dry eye disease, upregulated T helper 17 and 22 cells, and Demodex theories. The main symptoms of DAOSD are irritation/pain, redness, pruritus, discharge, and light sensitivity. Patients with AD and DAOSD as an adverse event develop various types of ocular surface disease, including blepharitis, blepharoconjunctivitis, conjunctivitis, keratoconjunctivitis, and keratitis. In ophthalmologic practice, to diagnose and treat DAOSD, physicians must understand the condition of the patient, make a differential diagnosis of conjunctivitis, determine concurrent dry eye, and assess DAOSD severity. Red flags for ophthalmologic intervention have been reported by organizations and institutions in various countries, which have highlighted the need for appropriate ophthalmologic intervention. Treatment of DAOSD involves topical treatments with artificial tears, antiallergic drugs, corticosteroids, and immunosuppressive drugs. In conclusion, patients with severe DAOSD require ophthalmologic intervention, and clinical collaboration between ophthalmologists and dermatologists is crucial for patients with AD during dupilumab treatment. This review can assist ophthalmologists in their daily practice and in their management of patients with DAOSD.
