摘要

ASA (aspirin) hypersensitivity occurs in approximately 2-23% of asthmatic patients and 21-30% of chronic urticaria patients. The clinical manifestations of ASA hypersensitivity can affect two major target organs, the skin called as ASA intolerant urticaria (AIU), and the respiratory tract called as ASA intolerant asthma (AIA), though these rarely occur in combination. Previous studies have reported that HLA DPB1~*0301 may be a HLA allele marker for AIA compared to ASA tolerant asthma group and HLA DRB1~*1302-DQB1~*0609 may be a marker for AIU compared to controls. In this study, in order to evaluate whether HLA alleles can be used as genetic markers for differentiating the two major ASA hypersensitivity phenotypes, we analyzed three HLA alleles, namely, HLA-DPB1~*0301, DRB1~*1302 and DQB1~*0609 by high-resolution genotyping in a larger cohort based on the homogenous Korean population.
