Abstract

Provided is a method for evaluating a drug anaphylactic reaction caused by antiepileptic drug phenytoin with HLA allele. The drug anaphylactic reaction comprises a Steven Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN) or a drug reaction with eosinophiliaand systemic symptoms (DRESS). The gene polymorphism (including CYP2C9, CYP2C19, CYP2C8 and CYP2C18) of CYP2C genes, HLA gene types (including HLA-A*0207, HLA-A*2402, HLA-B*1301, HLA-B*1502, HLA-B*4001, HLA-B*4609, HLA-B*5101, HLA-DRB1*1001 and HLA-DRB1*1502) and the concentration of phenytoin in plasma of a patient all may cause phenytoin adverse drug reactions.

Description

[0001] The present invention is a divisional application of a patent application whose filing date is December 19, 2013, application number is 201180071752.1, and the title of the invention is "Method for Evaluating the Risk of Adverse Drug Reaction Caused by Antiepileptic Drug Phenytoin". technical field

[0002] The invention relates to a method for predicting the risk of a patient's adverse drug reaction, especially the risk assessment of the allergic reaction caused by the antiepileptic drug phenytoin. Background technique

[0003] Adverse drug reactions (ADRs for short) are manifestations of harm caused by the use of drugs at normal doses. Drug allergic reaction is a common adverse reaction in drug therapy and accounts for about 20% of reported adverse drug reaction cases. These reactions can range from mild erythematous eruption (MPE) to life-threatening drug rash with eosinophilia and systemic symptoms (DRESS), Stevenson-Johnson syndrome (SJS) and toxic epidermal necr...
