Carbamazepine, an anticonvulsant and a mood-stabilizing drug, is the main cause of the Stevens-Johnson syndrome (SJS) and its related disease, toxic epidermal necrolysis (TEN), in Southeast Asian countries. Carbamazepine-induced SJS-TEN is strongly associated with the HLA-B*1502 allele. We sought to prevent carbamazepine-induced SJS-TEN by using HLA-B*1502 screening to prospectively identify subjects at genetic risk for the condition.

Rx Annotation for carbamazepine and HLA-B

Main Findings

Prospective screening for HLA-B*15:02 significantly decreased the incidence of carbamazepine-induced Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) (p<0.001)

Dosing Protocol

HLA-B*15:02-positive patients who did not take carbamazepine (n=367)HLA-B*15:02-negative patients who received carbamazepine (n=4120)Historical incidence
Number with SJS/TEN0010

Additional Findings

Mild, transient rash and itching developed in 211 subjects - 5 were HLA-B*15:02 positive. More severe cutaneous symptoms developed in 7 subjects - 1 was HLA-B*15:02 positive (urticaria).
