  • Publication number: 20240035089
    Abstract: The present invention provides a method for assessing the risk of drug hypersensitivity reaction caused by an antiepileptic drug with a sulfonamide derivative in a subject in need of such an assessment, comprising the step of detecting the presence of HLA-B alleles in the sample obtained from the subject, wherein the presence of the allele indicates that the subject has an increased risk of developing drug hypersensitivity reaction caused by the antiepileptic drug with the sulfonamide derivative. The present invention also provides a method for treating or reducing the incidence of such drug hypersensitivity reaction. Also provided are a test kit for assessing the risk of a patient developing drug hypersensitivity reaction caused by an antiepileptic drug with a sulfonamide derivative, comprising a reagent for determining specific HLA alleles, and use of the test kit in assessing the risk of a patient developing drug hypersensitivity reaction caused by an antiepileptic drug with a sulfonamide derivative.

  • Patent number: 10883142
    Abstract: A method of predicting the risk of a patient for developing phenytoin-induced adverse drug reactions (ADRs), including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), or drug reactions with eosinophilia and systemic symptoms (DRESS) is disclosed. Genetic polymorphisms of CYP2C genes (including rs1057910 (CYP2C9*3) and rs3758581 on CYP2C19), and HLA alleles (including HLA-B*1502, HLA-B*1301, and HLA-B*5101) can predict adverse reactions caused by phenytoin or fosphenytoin. Accordingly, the present invention provides a kit to assess the risk of a patient for developing adverse reactions in response to phenytoin-related drugs, which comprises the determination of the presence of a specific allele selected from the group consisting of rs1057910 (CYP2C9*3), rs3758581 on CYP2C19, HLA-B*1502, HLA-B*1301, and HLA-B*5101, wherein the presence of at least one allele is indicative of a risk for the adverse drug reactions.

  • Publication number: 20120077192
    Abstract: The present invention provides a method of predicting the risk of a patient for developing adverse drug reactions, particularly SJS or TEN. It was discovered that an HLA-B allele, HLA-B* 1502, is associated with SJS/TEN that is induced by a variety of drugs. The correlation with HLA-B* 1502 is most significant for carbamazepine-induced SJS/TEN, wherein all the patients tested have the HLA-B* 1502 allele. In addition, another HLA-B allele, HLA-B*5801, is particularly associated with SJS/TEN induced by allopurinol. Milder cutaneous reactions, such as maculopapular rash, erythema multiforme (EM), urticaria, and fixed drug eruption, are particularly associated with a third allele, HLA-B *4601. For any of the alleles, genetic markers (e.g., HLA markers, microsatellite, or single nucleotide polymorphism markers) located between DRB1 and HLA-A region of the specific HLA-B haplotype can also be used for the test.
