PIAMA出生队列研究中的哮喘症状和用药情况:治疗不足和治疗过度的相关证据
2011/08/31
摘要
目的:哮喘治疗不足和治疗过度都是很严重的问题,特别是在年幼儿童,但目前尚缺乏这方面的证据,而且尚未有纵向研究的数据。本文旨在研究年幼儿童中吸入性治疗方法的使用是否与2~8岁时的哮喘症状一致。
方法:数据来自《哮喘和尘螨过敏的预防和发病率出生队列研究》,3963名荷兰出生的儿童入选。对2~8岁的儿童采用每年邮寄问卷调查进行随访。评价年龄特异性哮喘症状患病率,而且与报道的吸入支气管扩张剂和/或糖皮质激素治疗相比较。
结果:现患喘息的比例随着年龄增长而降低。约有1/3的现患喘息者,在症状出现时并不使用吸入药物治疗。8岁时,30%主诉有严重现患哮喘症状的儿童并不使用吸入性糖皮质激素治疗。另一方面,高达50%采用糖皮质激素吸入治疗至少2年的患儿,在2年内的治疗期内无任何喘息症状。
结论:有症状但未给予恰当治疗的喘息患儿比例在整个儿童期比较高,即使当父母主诉症状持续或严重时也如此。无症状儿童的糖皮质激素吸入治疗随着年龄增长而增加,在8岁时糖皮质激素吸入治疗儿童占全部入选儿童的1/3。这些结果显示哮喘治疗不足和过度治疗情况很常见。

Abstract
OBJECTIVE: Under and overtreatment of asthma may be a serious problem especially in young children, but the evidence is scarce and no longitudinal data are available. Our aim was to investigate whether inhaled medication use in young children was in agreement with asthma symptoms at the age of 2-8 yr.
METHODS: Data were used from the ’Prevention and Incidence of Asthma and Mite Allergy’ birth cohort, consisting of 3963 children born in the Netherlands. Between age 2 and 8 yr, children were followed up using annual postal questionnaires. Age-specific prevalences of asthma symptoms were assessed and compared with reported use of inhaled bronchodilators and/or corticosteroids.
RESULTS: The proportion of current wheeze decreased with age. About a third of ’current wheezers’ did not use any inhaled medication during the years in which symptoms were reported. At 8 yr, 30% of children with reported ’severe current asthma symptoms’ were not using inhaled corticosteroids. On the other hand, up to 50% of children with inhaled corticosteroids for at least 2 yr did not report any wheezing during those 2 yr.
CONCLUSION: The proportion of symptomatic children without appropriate treatment was substantial throughout childhood, even when parents reported prolonged or severe symptoms. Treatment of asymptomatic children with inhaled corticosteroids increased with age and accounted for up to a third of all inhaled steroid use at 8 yr. These findings suggest that under and overtreatment of asthma in children was common.
