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.

Abstract: A method for assessing the risk of cutaneous adverse drug reactions (CADRs) caused by an epidermal growth factor receptor inhibitor is provided, wherein the CADRs comprises but not limited to: maculopapular eruption (MPE), erythema multiforme (EM), Stevens Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug rash with eosinophilia and systemic symptoms (DRESS). Also provided is a detection kit for assessing the risk of developing CADRs in patients, said kit comprising a reagent for determining specific HLA alleles and a use of the detection kit in assessing the risk of developing CADR in a patient.

Abstract: A method for assessing the risk of severe cutaneous adverse drug reactions (SCARs) induced by disease-modifying antirheumatic drugs is provided, wherein the severe cutaneous adverse drug reactions comprises but not being limited to: Stevens-Johnson Syndrome (SJS), toxic epidermal necrolysis (TEN) and drug rash with eosinophilia and systemic symptoms (DRESS). Also provided is a detection kit for assessing the risk of developing cutaneous adverse drug reactions in a subject, said kit comprising a reagent for determining specific HLA alleles and a use of the detection kit in assessing the risk of developing cutaneous adverse drug reactions in a subject.
