Abstract: Objective To investigate the etiology of toxic epidermal necrolysis. Methods The process of diagnosis and treatment of one case of toxic epidermal necrolysis was reviewed. The causes of serious drug adverse reactions were analyzed based on drug screening, pathogen detection and genetic detection. Results The drugs that might have caused toxic epidermal necrolysis included cefoperazone sulbactam sodium, loperamide and pantoprazole. The Narranjo score failed to distinguish suspicious drugs. The ALDEN score judged the three drugs as“probable”, “possible” and “possible”. Genetic test showed that the patient did not have any mutation of human leukocyte antigen alleles. The etiology of the patient's blood detected the fine ring virus type 16, type 27 and human herpes virus type 5, which might have increased the susceptibility to the disease. Conclusion The toxic epidermal necrolysis of this patient might have been caused by cefoperazone sulbactam sodium along with viral infection and low immunity.
