Abstract
Background:GLCCI1 rs37972 has previously been associated with decreased lung function improvement upon treatment with inhaled corticosteroids (ICS) in asthmatics. Aim: To assess whether variation in rs37972 is associated with altered ICS efficacy in north European asthmatic children and young adults with a reported use of ICS. Patients & methods: rs37972 was genotyped in three cohort studies of asthmatic children with a reported use of ICS. As an indicator for asthma exacerbations, asthma-related hospital visits and oral corticosteroid use were studied. Asthma control was assessed using a questionnaire. Results: rs37972 T allele was not significantly associated with an increased risk of oral corticosteroid use (summary odds ratio: 1.20; 95% CI: 0.99-1.45), an increased risk of asthma-related hospital visits (summary odds ratio: 1.07; 95% CI: 0.89-1.29), uncontrolled symptoms (summary odds ratio: 1.01; 95% CI: 0.75-1.36) or higher ICS dosages (summary ß: 0.01, 95% CI:-0.06-0.08). Conclusion: Variation in GLCCI1 rs37972 genotype does not seem to affect ICS efficacy in north European asthmatic children.
