Description

In the United States, Puerto Ricans and Mexicans have the highest and lowest asthma prevalence, morbidity, and mortality, respectively. Ethnic-specific differences in the response to drug treatment may contribute to differences in disease outcomes. Genetic variants at the β2-adrenergic receptor (β2AR) may modify asthma severity and albuterol responsiveness. We tested the association of β2AR genotypes with asthma severity and bronchodilator response to albuterol in Puerto Ricans and Mexicans with asthma.  Ethnic-specific pharmacogenetic differences exist between Arg16Gly genotypes, asthma severity, and bronchodilator response in Puerto Ricans and Mexicans with asthma. These findings underscore the need for additional research on racial/ethnic differences in asthma morbidity and drug responsiveness.
