简要总结
This study is designed to investigate whether the Phosphodiesterase 4 gene variability could be implicated in the salbutamol responsiveness in asthmatic children.
详细描述
Patients from 6 to 18 years old with asthma and receiving a treatment by salbutamol according to the usual care will be recruited. Saliva from patients will be collected using Oragen®.DNA OG-575 kit.

入选标准
- •Children 6-18 years
- •Asthma: confirmed asthma symptoms (wheeze, cough, dyspnea, chest tightness) and evidence for variable airflow limitation (≥ 12% increase in post bronchodilator FEV1, or ≥ 20% decrease in FEV1 post methacholine)
- •Spirometry prescribed for follow-up
- •Airflow limitation: FEV1<80% and/or FEV1/FVC <80 pre-bronchodilator
排除标准
- •no exclusion criteria
结局指标
主要结局
pre- and post-bronchodilator VEMS value
时间窗: Day 0
comparison of acute response to salbutamol calculated as the percentage difference between the pre- and post-bronchodilator VEMS value (BDR = 100 x \[post-VEMS - pre-VEMS\]/pre-VEMS) according to the genotype of the rs1504982
次要结局
- Screening other SNPs (other genes than PDE4) associated with the response to salbutamol in childhood asthma using SNP tags(Day 0)
- Locating other regions of the PDE4 gene that may be associated with the response to salbutamol by gene mapping (using SNP tags)(Day 0)
