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.
期刊介绍:
Pharmacogenetics and Genomics is devoted to the rapid publication of research papers, brief review articles and short communications on genetic determinants in response to drugs and other chemicals in humans and animals. The Journal brings together papers from the entire spectrum of biomedical research and science, including biochemistry, bioinformatics, clinical pharmacology, clinical pharmacy, epidemiology, genetics, genomics, molecular biology, pharmacology, pharmaceutical sciences, and toxicology. Under a single cover, the Journal provides a forum for all aspects of the genetics and genomics of host response to exogenous chemicals: from the gene to the clinic.
