Abstract

Abstract : Steven–Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are characterized by loss of the epidermis, often accompanied by sloughing of the oral mucosa and airway, which may be associated with the need for mechanical ventilation. We retrospectively examined our SJS and TEN population for factors predictive of the need for mechanical ventilation and mortality. Over more than a 7-year period, 74 subjects of ≥18 years old with biopsy-confirmed SJS–TEN were identified. Variables within the first 3 days of admission and throughout the entire hospital stay were analyzed for their value in predicting the need for mechanical ventilation and mortality. Predictive variables were examined using univariate and multivariate logistic regression analyses. Of our 74 subjects, 28 (37.8%) required mechanical ventilation and 11 (13.9%) died, all of whom were intubated. Patients requiring ventilation had a significantly higher %TBSA loss of epidermis on admission and progressive epidermal loss after admission. On multivariate analysis, acute kidney injury within the first 3 days of admission and fewer days from symptom onset to admission were statistically significant in predicting need for mechanical ventilation. In addition, the early need for mechanical ventilation, early serum bicarbonate <20 mm/L, and older age were all associated with higher mortality on multivariate analysis. In conclusion, the need for mechanical ventilation in adult TEN subjects is associated with higher mortality. This is the first time that mechanical ventilation has been specifically examined in the recent U.S. SJS and TEN population. The early recognition of patients at risk for ventilation may help guide management, especially in those patients admitted early after symptom development with acute kidney injury and extensive, progressing epidermal loss.
