BackgroundStevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but severe adverse drug reactions with high mortality. The use of corticosteroids and the management of complications (e.g. infection) in SJS/TEN remains controversial.MethodsA retrospective study was performed among 213 patients with SJS/TEN who were hospitalized in our department between 2008 and 2018, to investigate the causative agents, clinical characteristics, complications, and prognoses of SJS/TEN mainly treated by systemic corticosteroids combined with intravenous immunoglobulin (IVIG).ResultsThe causative drugs of SJS/TEN in these patients mainly consisted of antibiotics (61/213, 28.6%), anticonvulsants (52/213, 24.4%), and nonsteroidal anti-inflammation drugs (24/213, 11.3%), among which carbamazepine was the most frequently administered drug (39/213, 18.3%). There were significant differences in the maximum dosage, time to corticosteroid tapering, and the total dosage of corticosteroid between the SJS group and the TEN group, as well as among the three groups (P = 0.000), whereas in the initial dose of corticosteroid was not statistically significant among the three groups (P = 0.277). In a series of 213 cases, 18.4 cases (8.6%) were expected to die based on the score for the toxic epidermal necrolysis (SCORTEN) system, whereas eight deaths (3.8%) were observed; the difference was not statistically significant (P = 0.067; SMR = 0.43, 95% CI: 0.06, 0.48). The most common complications were electrolyte disturbance (174/213, 81.7%), drug-induced liver injury (64/213, 30.0%), infection (53/213, 24.9%), and fasting blood sugar above 10 mmol/L (33/213, 15.5%). Respiratory system (22/213, 10.3%) and wound (11/213, 5.2%) were the most common sites of infection. Multivariate logistic regression analysis indicated that the maximum blood sugar (≥10 mmol/L), the time to corticosteroid tapering (≥12 d), the maximum dosage of corticosteroid (≥1.5 mg/kg/d), and the total body surface area (TBSA) (≥10%) were defined as the most relevant factors of the infection.ConclusionThe mortality of patients in this study was lower than that predicted by SCORTEN, although there was no significant difference between them. Hyperglycemia, high-dose corticosteroid, and the TBSA were closely related to the infections of patients with SJS/TEN.Copyright © 2019. Published by Elsevier Ltd.
