Tumor necrosis factor-α inhibitor for successful treatment of toxic epidermal necrolysis with severe infection: a case series.

Abstract

Toxic epidermal necrolysis (TEN) is a rare severe cutaneous adverse reaction that involves more than 30% of the body surface area. TEN can be accompanied by a series of systemic symptoms and has a high risk of death. Tumor necrosis factor (TNF)-α inhibitors such as adalimumab and etanercept have been shown to be safe and effective for the treatment of TEN in some cases. However, clinical data on the use of TNF-α inhibitors to treat TEN with severe systemic infection are scarce. In the present study, three adult patients who developed TEN with serious active infection were successfully treated with etanercept. One of the three patients had active open pulmonary tuberculosis, and the other two had septicemia and/or fungal sepsis. All patients' skin lesions significantly improved after several days, and none of the patients developed emerging or re-emerging infectious diseases, adverse reactions, or a similar rash during follow-up. TNF-α inhibitors may be an effective treatment choice for TEN with severe systemic infection. However, further studies with large samples are still required for validation because clinical experience is limited.
