Up to 10% of patients show cutaneous adverse reactions ranging from relatively mild maculopapular exanthema (MPE) to severe drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). Although rare, DRESS, SJS and TEN show a high mortality rate of 10% to 50%. The human leukocyte antigen allele HLA-A*31:01 is predominantly associated with carbamazepine-induced MPE, DRESS and SJS/TEN in Europeans and Japanese. Also in Chinese, the allele is a risk factor for MPE and DRESS. Another HLA allele, HLA-B*15:02, is strongly associated with carbamazepine-induced SJS/TEN in many Asian populations, where the prevalence of the allele can be up to 25%. According to the Clinical Pharmacogenetics Implementation Consortium (CPIC) guidelines, patients positive for HLA-A*31:01 or HLA-B*15:02 should not be treated with carbamazepine. Thus, testing of patients prior to starting therapy will significantly reduce the incidence of severe hypersensitivity reactions.
