Use of Dupilumab to Treat Cutaneous Complications of Continuous Prostacyclin Infusion in Pulmonary Hypertension: A Case Report and Review of Literature.

Adhesive reactions are common complications of continuous treprostinil infusions, limiting their recommended use as a treatment for severe pulmonary hypertension. We present the case of a 10-year-old male with recurrent adhesive-related skin reactions, which compromised both subcutaneous and intravenous continuous treatment. Due to comorbid atopic dermatitis (AD), dupilumab was initiated to decrease skin reactions to adhesives. Within 48 h of initiation, skin reactions completely resolved. With sustained dupilumab treatment, he remains symptom-free and is successfully tolerating intravenous treprostinil infusion.
