RT Journal Article SR Electronic T1 Cyclosporine as an alternative immunosuppressant for steroid-resistant drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e250983 DO 10.1136/bcr-2022-250983 VO 16 IS 3 A1 Katrina Tan A1 Adam Testro YR 2023 UL http://casereports.bmj.com/content/16/3/e250983.abstract AB Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a multiorgan reaction associated with a broad range of commonly used medications. Most cases of DRESS syndrome resolve with cessation of the inciting agent; however, use of systemic immunosuppression, most commonly with oral corticosteroids, is also recommended in cases with visceral organ involvement.We report a case of steroid-resistant relapsing–remitting DRESS syndrome secondary to sulfasalazine. Our patient experienced significant flare of symptoms of DRESS syndrome with multiple attempts to wean prednisolone. Initiation of cyclosporine as an alternative immunosuppressive agent to long-term corticosteroids has resulted in a 6-month remission in both dermatological and hepatic sequelae of DRESS syndrome.
