Dupilumab in Chronic Actinic Dermatitis: a retrospective case series.

We report a retrospective case series from two UK photobiology units of twelve patients with concomitant Atopic Dermatitis and Chronic Actinic Dermatitis treated with dupilumab as a systemic monotherapy. Whilst dupilumab is an effective therapy for moderate-severe AD, our results suggest that it may be less effective for the photosensitivity of CAD. In 11 of 12 patients with CAD, dupilumab was associated with improvement in dermatitis, but only half of patients noted improvement in photosensitivity.
