    Abstract:
    Drug-induced hypersensitivity syndrome/drug reaction with eosinophilia and systemic symptoms is a life-threatening severe cutaneous adverse reaction, characterized by multiple organ involvement and reactivation of herpes viruses. Although the mainstay of treatment is a high dosage of corticosteroids delivered by pulse therapy or conventional oral administration, it remains debatable which mode is better. To clarify this issue, we reviewed publications in Japan of 299 cases of drug-induced hypersensitivity syndrome/drug reaction with eosinophilia and systemic symptoms treated with corticosteroids, to evaluate safety concerns with regards to these two modes of treatment. As a result, we found that patients treated with pulse therapy more frequently suffered cytomegalovirus reactivation, persistency, and high mortality but less frequently experienced herpesvirus 6 reactivation or type 1 diabetes compared with those undergoing conventional treatment, suggesting that the administration mode may differentially modulate inflammatory responses toward distinct consequences. This is the first statistical analysis revealing that steroid pulse therapy frequently resulted in severe sequelae with high mortality. In terms of the risk of serious consequences, we consider that steroid pulse therapy should be eschewed for the treatment of drug-induced hypersensitivity syndrome/drug reaction with eosinophilia and systemic symptoms.
