Background: Drug reaction with eosinophilia and systemic symptoms is an outcome of a complex interaction between specific drugs, certain herpesviruse types and the immune system of the affected individual and is characterized by an unpredictable course and recurrent flares even after withdrawal of the offending drug and administration of systemic steroids. Aims: To identify the predictors of disease severity in drug reaction with eosinophilia and systemic symptoms. Methods: After obtaining ethical clearance from the institutional ethics committee and a written informed consent from individual study participant, the first hundred patients who required inpatient care in Government Medical College, Kozhikode with drug reaction with eosinophilia and systemic symptoms from January 1st 2011 were included in this study aimed to identify the predictors of disease severity in drug reaction with eosinophilia and systemic symptoms. Results: Male-to-female ratio of the study group was 0.8:1. The presence of atypical cells in peripheral smear and advanced age were found to be predictors of disease severity in drug reaction with eosinophilia and systemic symptoms, whereas, sex, facial erythema and edema and absolute eosinophil count were found not to be predictors of the same. Limitations: The main limitation of this study was our inability to assess the role of human leukocyte antigen (HLA) association and herpes virus reactivation in disease severity in drug reaction with eosinophilia and systemic symptoms. This study was also not designed to evaluate the response to treatment given and the mortality caused by drug reaction with eosinophilia and systemic symptoms. Conclusions: Studies on the predictors of severity in drug reaction with eosinophilia and systemic symptoms in different population groups may enable us to identify the warning signs and help to formulate the standard therapeutic guidelines.
