title: Comparison of the causes and clinical features of drug rash with eosinophilia and systemic symptoms and stevens-johnson syndrome.
abstract: OBJECTIVE
  Drug rash with eosinophilia and systemic symptoms (DRESS) and the Stevens-Johnson syndrome (SJS) are both severe drug reactions. Their pathogenesis and clinical features differ. This study compared the causes and clinical features of SJS and DRESS.
  
  
  METHODS
  We enrolled 31 patients who were diagnosed with DRESS (number=11) and SJS (number=20). We retrospectively compared the clinical and laboratory data of patients with the two disorders.
  
  
  RESULTS
  In both syndromes, the most common prodromal symptoms were itching, fever, and malaise. The liver was commonly involved in DRESS. The mucosal membrane of the oral cavity and eyes was often affected in SJS. The most common causative agents in both diseases were antibiotics (DRESS 4/11 (37%), SJS 8/20 (40%)), followed by anticonvulsants (DRESS 3/11 (27%), SJS 7/20 (35%)). In addition, dapsone, allopurinol, clopidogrel, sulfasalazine and non-steroidal anti-inflammatory drugs (NSAIDs) were sporadic causes.
  
  
  CONCLUSIONS
  The most common causes of DRESS and SJS were antibiotics, followed by anticonvulsants, NSAIDs and sulfonamides. The increase in the use of antibiotics in Korea might explain this finding.
