Background: Toxic epidermal necrolysis (TEN) is a severe, progressive disease characterized by the sudden onset of skin necrosis. It is frequently associated with systemic involvement and has a high rate of morbidity and mortality. Standard therapy includes meticulous wound care, fluid replacement, and nutritional support in an intensive care setting.
Objective: We evaluated the outcomes of patients treated in a burn unit for TEN over a 9-year period and compared the outcomes of a subset of patients treated with plasmapheresis with those managed by conventional means.
Methods: The records of 16 patients with a diagnosis of TEN obtained from a computerized database were reviewed. Parameters recorded included extent of body surface area involvement and number of mucous membranes involved at admission, complications such as sepsis or need for mechanical ventilation, length of stay, and disposition.
Results: Sixteen patients were included in this study. Ten were treated with conventional support measures alone. Six were treated with plasmapheresis. The average age was 42.4 years; the male/female ratio was 1:2.2. Sulfamethoxazole/trimethoprim was implicated in causation in 6 patients. The average extent of involvement on admission in all patients was 51.5% total body surface area. The average length of stay in all patients was 14.8 days. Eight patients (50%) were discharged home, 4 (25%) were discharged to a rehabilitation facility, and 4 (25%) died (2 of sepsis, 2 of cardiopulmonary arrest). None of the plasmapheresis-treated patients died.
Conclusion: Plasmapheresis is a safe intervention in extremely ill TEN patients and may reduce the mortality in this severe disease. Prospective studies are needed to further define its usefulness.
