Toxic epidermal necrolysis pdf

Complications Dehydration, sepsis, pneumonia, multiple organ failure. The most common cause is certain medications such as toxic epidermal necrolysis pdf, carbamazepine, allopurinol, sulfonamide antibiotics, and nevirapine. Treatment typically takes place in hospital such as in a burn unit or intensive care unit. SJS usually begins with fever, sore throat, and fatigue, which is commonly misdiagnosed and therefore treated with antibiotics.

TEN, and TEN are often heralded by fever, sore throat, cough, and burning eyes for 1 to 3 days. SJS is thought to arise from a disorder of the immune system. The immune reaction can be triggered by drugs or infections. Genetic factors are associated with a predisposition to SJS. Although SJS can be caused by viral infections and malignancies, the main cause is medications. A leading cause appears to be the use of antibiotics, particularly sulfa drugs. Typically, the symptoms of drug-induced SJS arise within a week of starting the medication.

The second most common cause of SJS and TEN is infection, particularly in children. In pediatric cases, Epstein-Barr virus and enteroviruses have been associated with SJS. Recent upper respiratory tract infections have been reported by more than half of patients with SJS. Fungal infections with coccidioidomycosis, dermatophytosis, and histoplasmosis are also considered possible causes.

And TEN are often heralded by fever, benzodiazepine dependence: focus on withdrawal syndrome”.

T cells to initiate autoimmune responses. Studies indicate that the mechanism by which a drug or its metabolites accomplishes this involves subverting the antigen presentation pathways of the innate immune system. TEN, or TEN and the intake of specific drugs as determined in certain populations are given in HLA associations with SCARs. In either case, this binding appears to develop only on certain T cell receptors. Since the genes for these receptors are highly edited, i. SJS, like TEN and erythema multiforme, is characterized by confluent epidermal necrosis with minimal associated inflammation.
