哮喘患者对吸入性皮质类固醇(ICS)的反应是可变的,难以量化。我们的目的是确定一个衡量类固醇反应适合药物遗传学研究的纵向和横向队列。使用儿童哮喘管理项目(CAMP)哮喘队列的纵向数据,我们定义了横截面哮喘类固醇反应(CASTER)测量横截面数据。然后,我们将其应用于四个独立哮喘队列的横截面切片:改善哮喘控制试验(IMPACT),沙美特罗或皮质类固醇研究(SOCS),儿科哮喘控制者试验(PACT)和哥斯达黎加哮喘遗传学研究(GACRS)。CASTER在儿童哮喘队列:GACRS、PACT以及CAMP的横断面数据上达到了高准确性(AUC分别为82%、71%、63%)。这表明,选择横断面临床信息足以识别儿童哮喘ICS治疗的良好和不良反应者。因此,CASTER代表了哮喘研究中类固醇反应测量的可用性和适用性的重大改进。
Asthma patient response to inhaled corticosteroids (ICS) is variable and difficult to quantify. We aimed to define a measure of steroid response suitable for pharmacogenetic research in longitudinal and cross-sectional cohorts. Using longitudinal data from the Childhood Asthma Management Program (CAMP) asthma cohort, we defined the Cross-sectional Asthma STEroid Response (CASTER) measure in cross-sectional data. We then applied this to cross-sectional slices of four independent asthma cohorts: The Improving Asthma Control Trial (IMPACT), the Salmeterol or Corticosteroids Study (SOCS), the Pediatric Asthma Controller Trial (PACT), and the Genetics of Asthma in Costa Rica Study (GACRS). CASTER achieved high accuracy on the childhood asthma cohorts: GACRS, PACT, and also on cross-sectional data from CAMP (AUCs 82%, 71%, 63%, respectively). This demonstrates that select cross-sectional clinical information is sufficient to identify good and poor responders to ICS treatment in childhood asthma. Thus, CASTER represents a major improvement in the usability and applicability of steroid response measures in asthma research.
