HLA-B*1502 and carbamazepine induced StevensJohnson syndrome/toxic epidermal necrolysis in Indonesia

Background & Objective: Association between HLA-B*1502 and carbamazepine-induced StevenJohnson syndrome/toxic epidermal necrolysis (CBZ-SJS/TEN) was reported in many Southeast Asian populations but not in Indonesian. The purpose of this study was to evaluate the association between HLA-B*1502 andCBZ-SJS/TEN in an Indonesian population. Methods: Patients with history of CBZ-SJS/TEN are recruited as cases and those who tolerated CBZ as controls. HLA-B typing was performed. Results: We recruited 14 cases with CBZ-SJS/TEN and 53 controls. Positive HLA-B*1502 was found in 8 (57.1%) cases and 14 (26.4%) controls (OR 3.7, 95% CI 1.09-12.61, p=0.035). Conclusion: HLA-B*1502 is associated with CBZ-SJS/TEN patients in Indonesian.
