Updated analysis of the pharmacogenomics of pediatric bronchodilator response

Year: 2024

Type: article

Abstract: This short communication serves as an update to previously published pilot study results on bronchodilator response (BDR) in children with asthma. We expanded our cohort from 54 to 165 pediatric patients seeking emergency department care for an asthma exacerbation. We obtained measured BDR before and after albuterol administration using the Pediatric Asthma Severity Score and collected genomic DNA. Based on a literature review, we analyzed whether 21 candidate single-nucleotide polymorphisms (SNPs) were associated with BDR. Among the three SNPs initially reported in our pilot study as significantly associated with BDR (rs912142, rs7081864, and rs7903366), we confirmed that rs7081864 was still significantly associated with suboptimal BDR (odds ratio, 0.47; confidence interval, 0.24-0.92). If externally validated in broader studies, simple outpatient testing for that SNP variant could help guide pharmacologic therapy for acute asthma symptoms.
