Upper airway involvement in Stevens–Johnson syndrome and toxic epidermal necrolysis
2019
Abstract Background Stevens–Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare life-threatening hypersensitivity conditions associated with epidermal detachment and mucositis. The indication for flexible nasoendoscopy (FNE) and overall predictive factors for early intubation are unclear. Objectives To describe the incidence of airway involvement and the key indicators for intubation in our SJS or TEN patient cohort. To determine the association between FNE findings and early intubation. Methods A retrospective review of 45 patients with biopsy proven SJS or TEN admitted to an Australian tertiary burns centre from 2010 to 2017. Results Thirty-five patients were diagnosed with TEN (77.8%), followed by overlap syndrome (SJS-TEN) (n = 6, 13.3%) and SJS (n = 4, 8.9%). Twenty (44.4%) patients were intubated; and all 20 had a diagnosis of TEN (100.0%) (p Conclusion More than half (n = 20, 57.1%) of the 35 patients diagnosed with TEN underwent intubation, mainly to facilitate operative and dressing management. FNE was performed on most patients, however there was no clear association between FNE findings and early intubation.
