2岁前气道阻塞疾病严重程度可预测10岁时的哮喘发病情况
2008/06/06
挪威的学者近期发表于Thorax上的一篇报道评价了生命早期阶段气道阻塞性疾病(OAD)的严重程度与哮喘发生的关系。他们发现使用简单的评分系统,2岁前儿童OAD严重程度的高评分是哮喘发生的一个重要危险因子,该指标可能预示患儿10岁时出现哮喘。

BACKGROUND: Predicting school-age asthma from obstructive airways disease (OAD) in early life is difficult, even when parental and children’s atopic manifestations are taken into consideration.
OBJECTIVE: To assess if the severity of OAD in the first 2 years of life predicts asthma at 10 years of age.
METHODS: From a nested case control study within the Environment and Childhood Asthma study, 233 2-year-old subjects with recurrent (> or = 2 episodes) bronchial obstruction (rBO+) and 216 subjects without bronchial obstruction (rBO-) underwent clinical examination, parental interview, treadmill test and metacholine bronchial hyperresponsiveness (BHR) measurement at 10 years. A severity score at 2 years was calculated by frequency, persistence of bronchial obstruction and hospital admissions because of OAD.
MAIN OUTCOMES: Current asthma at 10 years (asthma with symptoms and/or asthma medication during the past year and/or positive treadmill test). Secondary outcome was metacholine BHR at 10 years.
RESULTS: Compared with rBO- subjects, adjusted odds ratio (95% CI) of current asthma among rBO+ was 7.9 (4.1, 15.3), and among rBO+ with a severity score of > 5, 20.2 (9.9, 41.3). In receiver operated characteristic analysis, positive and negative predictive values demonstrated the applicability and value of the score, with an optimal cut-off at severity score 5. Children with severity score > 5 had severe BHR more often (PD20 metacholine < 1 micromol) than children with a lower or 0 score (p = 0.0041). CONCLUSION: Using a simple scoring system, a high severity score of OAD by 2 years of age is a strong risk factor for, and may predict, current asthma at 10 years of age.
