儿童当前和长期哮喘控制的一致性有限:PACMAN队列研究
2011/08/31
摘要
背景:一些研究显示,哮喘治疗转归的预测因子存在差异,这取决于转归的定义。这表明,针对不同转归的研究可能反应了哮喘控制的不同方面。为评价哮喘控制预测因子,我们需要有确定的转归表型。本试验旨在研究当前和长期哮喘控制检测指标之间的相关性。
方法:采用皮质激素吸入治疗的527名哮喘患儿入选《儿童哮喘用药的药物基因学:抗炎治疗的队列研究》。采用哮喘控制问卷调查定义当前哮喘控制水平(过去1周)。采用全球哮喘倡议对长期哮喘控制进行评价。某个季节哮喘未达到最佳控制水平定义为出现≥3个下列项目:(i)日间或(ii)夜间症状,(iii)活动受限;(iv)急救药物治疗。(i)前一季和(ii)药物治疗前1年的哮喘控制水平作为长期哮喘控制的定义。比较当前和长期哮喘控制,研究两者的一致性。
结果:长期未控制的哮喘比例在秋季和冬季最高(50%),夏季最低(32%) (P<0.05)。当前和长期哮喘控制的总体一致性有限(前一季:66%;前一年:68%)。
结论:当前和长期哮喘控制的一致性有限。此外,我们还发现哮喘控制水平存在季节差异。因此,作为检测指标,检测长期哮喘控制水平,而不是当前哮喘控制水平,对于哮喘患者非常重要。

Abstract
BACKGROUND: Several studies have shown that predictors of asthma treatment outcomes differ depending on the definition of the outcome chosen. This provides evidence that different outcomes studied may reflect distinct aspects of asthma control. To assess predictors of asthma control, we need firm outcome phenotypes. The aim of this study was to investigate the association between measurements of current and long-term asthma control.
METHODS: We included 527 children using inhaled corticosteroids participating in the Pharmacogenetics of Asthma medication in Children: Medication with ANti-inflammatory effects cohort. Current asthma control (previous week) was defined using the Asthma Control Questionnaire. Long-term asthma control was based on Global Initiative for Asthma guidelines. Not well-controlled asthma in a season was defined as ≥3 of the following items present in a season: (i) day-time or (ii) night-time symptoms, (iii) limitations in activities, and (iv) rescue medication use. Asthma control during (i) the previous season and (ii) the year preceding the pharmacy visit was used as long-term asthma control definitions. Current and long-term asthma control were compared to investigate agreement.
RESULTS: Long-term uncontrolled asthma rates were highest in autumn and winter (50%) and lowest in summer (32%) (p < 0.05). Overall agreement between current and long-term asthma control was limited (66% for previous season and 68% for previous year).
CONCLUSION: Congruence between current and long-term asthma control was limited. Furthermore, we showed significant seasonal differences. It is therefore important to calculate asthma control over a longer period of time, instead of using current asthma control as indicator.
