Relapse of Sulfasalazine-Induced DRESS Syndrome Following the Administraton of Contrast Media: A Case Report

Sulfasalazine, a non-antibiotic sulfonamide, is associated with severe hypersensitivity reactions, including Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome. We report a case of sulfasalazine-induced DRESS syndrome that relapsed following the administration of visipaque® (iodixanol). Macular rashes, pruritus, and an acute exacerbation of dyspnea were immediately observed after the administration of contrast media. It seems that patients suffering from DRESS syndrome are sensitive to the administration of other new medications with a high possibility of hypersensitive reactions. It can be concluded that iodinated contrast media should be used cautiously in patients with DRESS syndrome.
