In 2017, the Food and Drug Administration approved dupilumab for patients with moderate to severe atopic dermatitis (AD) refractory to topical therapies; however, clinical trials specifically excluded patients with human immunodeficiency virus (HIV). Here, we describe the effective and uncomplicated treatment of AD with dupilumab over a 23-month period in a patient with HIV. Throughout the treatment duration, the patient demonstrated marked improvement in AD severity, while maintaining stable CD4 T cell counts and viral load. These results suggest that dupilumab represents a safe and effective treatment option for AD in patients with HIV.
