title: Stevens-Johnson Syndrome and toxic epidermal necrolysis: a multi-aspect comparative 7-year study from the People's Republic of China.
abstract: BACKGROUND
  Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but severe cutaneous drug reactions. They are differentiated based on the fraction of the body surface area affected. Optimal therapy for SJS and TEN is a controversial issue.
  
  
  OBJECTIVE
  We compared the treatments given to and the clinical outcomes of 39 cases of SJS and 48 cases of TEN seen at a single institution between January 2007 and December 2013 for better understanding of the clinical characteristics and development of the two conditions.
  
  
  METHODS
  Demographic data, clinical characteristics, treatments given, and therapeutic responses observed were retrospectively collected.
  
  
  RESULTS
  The incidence rates of hypoproteinemia and secondary infections are significantly higher in TEN than in SJS (P=0.001 and P=0.002, respectively). The corticosteroid dose did not influence the time from the initiation of therapy to control of the lesions in SJS, but increasing the dosage of corticosteroids progressively decreased the time from the initiation of therapy to control of the lesions in TEN. With increases in the utilization ratio of intravenous immunoglobulin (IVIG), the length of the hospital stay became shorter, whereas the time from the initiation of therapy to control of the lesions remained the same in SJS. However, for TEN, both the length of the hospital stay and the time from the initiation of therapy to control of the lesions became shorter with increases in the utilization ratio of IVIG.
  
  
  CONCLUSIONS
  SJS and TEN are two variants of the same spectrum, and they differ from each other not only in the severity of epidermal detachment but also in other clinical parameters and their distinct clinical courses. Thus, differential treatment of both conditions may have benefits for their prognosis.
