In the present study, nonsteroidal anti-inflammatory and anti-infective drugs were the most frequent causative agents (eight patients in each group). In the group of SJS and SJS/TEN patients treated with ST and SC, the mortality rate was 0%. In TEN patients, the mortality rate was 17.6% (three of 17 patients). There were no significant differences in mortality rate among the three TEN treatment groups, but the results may have been biased by the small number of patients.
