Etanercept therapy for toxic epidermal necrolysis.

BACKGROUND

Toxic epidermal necrolysis (TEN) is a severe and potentially lethal drug reaction for which no standard treatment is available.

OBJECTIVE

To describe a case series of patients with TEN treated with a single dose of etanercept.

METHODS

We observed 10 consecutive patients with TEN. For each patient, we recorded the presence of comorbidities and all the drugs recently started (ie, in the last month). In all cases, 50 mg of etanercept was administered in a single subcutaneous injection. The clinical severity of disease was computed using the SCORe of Toxic Epidermal Necrosis (SCORTEN) scale. Using the probabilities of death linked to each level of SCORTEN score, we calculated the expected probability of death in our patients. Healing was defined as complete reepithelialization, and a time to healing curve was then obtained using the Kaplan-Meier method.

RESULTS

All patients promptly responded to treatment, reaching complete reepithelialization without complications or side effects. The median time to healing was 8.5 days.

LIMITATIONS: This is a small, uncontrolled case series.

CONCLUSION

These preliminary results suggest the possibility that tumor necrosis factor-alfa may be an effective target for control of TEN, a dangerous skin condition for which no effective cure has yet been found.
