Patients with AD who develop conjunctivitis during dupilumab treatment may experience “bilateral inflammation of the anterior conjunctiva and hyperaemia of the limbus, which may cause nodular swelling.”according to the statement, which pertains to conjunctivitis in AD patients, “with and without dupilumab therapy.” (J Eur Acad Dermatol Venereol. 2019 May 6. doi: 10.1111/jdv.15608). Currently, there are no predictive factors of conjunctivitis and no guidance in the literature on how to manage conjunctivitis associated with dupilumab, which in some cases can make it necessary to stop treatment, the authors wrote.
The International Eczema Council (IEC) polled 86 dermatologists in 22 countries who are experts in AD; 46 members responded from 19 countries, including dermatologists from Australia, Canada, Denmark, France, Germany, Japan, Korea, the Netherlands, the United Kingdom, and the United States. The questions centered on the diagnosis and management of conjunctivitis in AD patients, and whether to refer cases to an ophthalmologist. Consensus was achieved if less than 30% of participants disagreed with a statement. IEC members then met in person at a European Academy of Dermatology and Venereology meeting in Paris to discuss the results of the survey. Survey respondents noted they had seen dupilumab-associated conjunctivitis in both pediatric and adult patients.
The IEC members recommended that:
- Patients should be informed about the risks of conjunctivitis before being prescribed dupilumab.
- AD patients should be asked “routinely” about ocular complaints or symptoms.
- AD patients with conjunctivitis should be referred to an ophthalmologist for diagnosis and treatment.
- AD patients with new-onset conjunctivitis during dupilumab treatment always should be referred to an ophthalmologist, especially in more severe cases such as when they do not respond to treatment with antihistamine or artificial tears.
- Dermatologists also should rule out keratoconjunctivitis before treating with dupilumab, as it may cause keratitis and blindness.
- Patients who have had keratoconjunctivitis in the past should not be precluded from treatment with dupilumab, and those who develop conjunctivitis during treatment should be referred to an ophthalmologist – but should stay on treatment while waiting for the consult.
“It was stressed that at this moment there are also no reliable data on the course of atopic keratoconjunctivitis and vernal keratoconjunctivitis during dupilumab treatment,” according to Jacob P. Thyssen, MD, PhD, Herlev and Gentofte Hospital, Hellerup, Denmark, and coauthors. These patients “should be carefully monitored by an ophthalmologist before and during treatment with dupilumab.”
The recommendations also centered around which treatments should be initiated by dermatologists, and which should be referred to ophthalmologists. Those patients with conjunctivitis should receive eye drops, eye ointment, or oral antihistamines from their dermatologists before an ophthalmology referral, the IEC members said. Dermatologists also should perform, or refer patients for, skin prick testing or specific IgE testing for aeroallergens in patients with AD who have conjunctivitis, and patch testing with an “ophthalmologic series, and native eye drops/ointments to diagnose possible delayed type hypersensitivity reactions to topical ingredients,” they added.
Among the treatments for conjunctivitis best left to ophthalmologists are cyclosporine, tacrolimus, or corticosteroid eye drops.
“Despite the more limited experience with eye drops by dermatologists, rapid access to ophthalmological service may be difficult, sometimes warranting a short course of corticosteroid eye drops without ophthalmological consultations,” Dr. Thyssen and associates said. “However, persistent or recurrent conjunctivitis requiring repeated or prolonged use of corticosteroid, tacrolimus, and ciclosporin-containing eye drops, must be managed by an ophthalmologist, given the risk of glaucoma, cataract, and infections.”
“The AD severity, conjunctivitis severity, possible contraindications, possible effect of dupilumab therapy on concomitant asthma or other comorbidities, as well as other treatment options, should be considered on an individual patient basis,” the authors concluded.
The IEC survey was limited by the small survey response and reliance on expert opinion.
The authors reported personal and institutional relationships in the form of grants, corporate sponsorships, advisory board memberships, investigator appointments, speakers bureau positions, and consultancies for a variety of pharmaceutical companies, agencies, societies, and other organizations. No funding was obtained for the study.
