ABSTRACT
Acute generalized exanthematous pustulosis (AGEP) is rarely caused by radiocontrast media (RCM). The role of skin tests for the diagnosis and evaluation of cross-reactivity in a delayed type of RCM-induced hypersensitivity have yet to be determined. Here, we report a case of iodixanol-induced AGEP where we safely administered alternative RCM using patch tests. A 44-year-old woman had coronary artery angiography (CAG) for the evaluation of ischemic heart disease. She was on regular hemodialysis because of end-stage renal disease. She was given iodixanol (Visipaque) during CAG. Approximately 1 day after CAG, she developed AGEP. The patient was rehospitalized for CAG again after 1 year. We performed skin tests to choose safe alternative RCM. Intradermal tests with iodixanol, iohexol (Bonorex) and Iopamidol (Pamiray) showed negative responses. Patch tests showed a positive response to iodixanol, equivocal to iohexol, and negative to Iopamidol. We finally chose Iopamidol and performed CAG successfully without any adverse reaction. Patch tests may be a useful tool for the diagnosis and choice of safe alternatives in RCM-induced delayed-type hypersensitivity reactions such as AGEP.
