Abstract:
Objective:To investigate the correlations of human leukocyte antigen (HLA)-A, B, C, and DRB1 genotypes with cross-reactivity caused by aromatic antiepileptic-drugs.Methods:A case-control association study was carried out on subjects who accepted treatments/physical examination in our hospitals from September 2016 and September 2020; 31 patients with aromatic antiepileptic drugs (carbamazepine, phenytoin, oxcarbazepine, lamotrigine and phenobarbital)-induced cross-reactivity were enrolled as patient group, 52 tolerant subjects who took the 5 antiepileptic drugs for more than 3 months without cross-reactivity were chosen as tolerant control group, and 500 healthy volunteers were recruited as normal control group. The ethnicity of all patients and controls was Han Chinese. High-resolution genotyping was performed to compare the HLA-A, B, C, and DRB1 genotypes in subjects of the 3 groups. χ2 test or Fisher's exact test were used to analyze the correlations of HLA genes with cross-reactivity caused by aromatic antiepileptic-drugs. Results:The presence of HLA-B*13:01 genotype in the patient group, the tolerant control group, and the normal control group was 45.2% (14/31), 15.4% (8/52) and 14.6% (73/500), respectively. The presence of HLA-B*13:01 genotype in the patient group was significantly higher as compared with that in the tolerant control group and normal control group ( Pc<0.017). No other HLA genotypes were found to be associated with cross-reactivity caused by aromatic antiepileptic-drugs. Conclusion:HLA-B*13:01 is the risk genotype for cross-reactivity caused by aromatic antiepileptic-drugs.
