steven johnson syndrome causes include seizure medications


Essentially all cases of TEN are temporally correlated with medications (Table 27), whereas about 25% of SJS cases are caused by infection or vaccination.

HIV infection, kidney disease, uncontrolled autoimmune disease, and human leukocyte antigen type (HLA-B_1502 and HLA-B_5801) also contribute to increased risk.

Patients of Asian and South Asian ancestry who are positive for HLA-B_1502 have up to a 10% risk for SJS/TEN when exposed to aromatic anticonvulsants (carbamazepine, phenytoin, and phenobarbital).

HLA-B_5801 positivity predicts risk of SJS/TEN upon exposure to allopurinol. The role of genetic screening to prevent these reactions is unsettled.1
