Use of Systemic Medications for Treating Adult Atopic Dermatitis in France: Results of a Practice Survey

PURPOSE: Recent studies have illustrated that systemic medications are underused for treating adult atopic dermatitis (AD) and that dermatologists have concerns regarding the safety profile of cyclosporine in AD. PATIENTS AND METHODS: We performed a national online practice survey between March and April 2020. RESULTS: A total of 305 dermatologists responded, 57% with hospital-based activity and 43% with private practice. Overall, 46.9% prescribed cyclosporine for adult AD. Before initiating treatment, 56.9% did not perform evaluation scoring. Reasons for not prescribing cyclosporine were no eligible patients (24.7%), lack of information (52.6%), need for hospital prescription (31.2%), and lack of experience (79.2%). Fifty-four percent of the dermatologists prescribed methotrexate for adult AD. Before initiating treatment, 50.5% did not perform evaluation scoring. Reasons for not prescribing methotrexate were no eligible patients (46.7%), lack of information (39.3%), lack of experience (25.2%), and not approved for AD (47.4%). A total of 2.1% dermatologists prescribed other systemic treatments for adult AD, 9.8% prescribed corticosteroids and 56.4% prescribed dupilumab. CONCLUSION: Systemic treatments for AD are used by half of dermatologists, although cyclosporine and dupilumab must be initiated in hospitals in France. Methotrexate is more frequently used than cyclosporine, although it is not approved for this indication in France. A vast majority of dermatologists do not perform any evaluation scoring before initiating systemic treatment for adult AD.
