The systemic treatments for drug reaction with eosinophilia and systemic symptoms (DRESS) beyond corticosteroids

Abstract

Drug reaction with eosinophilia and systemic symptoms (DRESS), also known as drug-induced hypersensitivity syndrome (DiHS), is a severe type of cutaneous adverse reaction. The gold standard therapy for DRESS involves the discontinuation of the culprit drug, supportive therapies, and administration of corticosteroids. However, in cases of primary treatment failure or suboptimal response, there arises an urgent need for alternative interventions. This review focuses on exploring alternative systemic therapies for patients with steroid-resistant DRESS, steroid-dependent DRESS, or refractory DRESS, encompassing immunosuppressive agents, intravenous immunoglobulin, plasmapheresis, biologics, and small molecule drugs, with an emphasis on their clinical efficacy and the underlying mechanisms in the treatment of DRESS. Furthermore, this review provides a summary of potential management strategies and laboratory workup during the treatment of DRESS.
