Drug-induced hypersensitivity syndrome (DiHS)/drug reaction with eosinophilia and systemic symptoms (DRESS) severity score: A useful tool for assessing disease severity and predicting fatal cytomegalovirus disease

The clinical course of drug-induced hypersensitivity syndrome/drug reaction with eosinophilia and systemic symptoms is unpredictable. We developed a scoring system to predict development of cytomegalovirus disease and complications. Using this scoring system, cytomegalovirus disease and complications could be preventable by prompt treatment with anti- cytomegalovirus agents.
