Abstract

The earliest respiratory function assessments, within or close to the neonatal period, consistently show correlations with lung function and with the development of asthma into adulthood. Measurements of lung function in infancy reflect the in utero period of lung development, and if early enough, show little influence of postnatal environmental exposures. Later in the preschool and school age periods, influences of the environment are superimposed on initial levels. Fetal exposures before birth such as maternal smoking during pregnancy, lead to reduced lung function and an increased risk of asthma in females particularly those with certain glutathione S-transferase genotypes. Lung function measurements later in the preschool period are also associated with development of asthma. Although lung function in preschoolers does help predict asthma in later life and these observations have increased our understanding of the physiology underlying asthma, the findings have not led to thewidespread use of lung function measurements being in preschoolers as clinical predictors of asthma due to the practicalities of testing in this age group.

学龄前儿童的肺功能是否有助于预测以后生活中的哮喘?
在新生儿期或接近新生儿期的早期呼吸功能评估一致显示与肺功能和成年后哮喘的发展相关。婴儿时期肺功能的测量反映了肺在子宫内的发育,如果足够早,出生后环境暴露的影响很小。后来在学龄前和学龄阶段,环境的影响叠加在初始水平上。胎儿出生前暴露于此类物质,如孕妇在怀孕期间吸烟,会导致肺功能下降,并增加女性患哮喘的风险,尤其是那些具有某些谷胱甘肽s -转移酶基因型的女性。学龄前后期的肺功能测量也与哮喘的发展有关。虽然学龄前儿童的肺功能确实有助于预测以后生活中的哮喘,这些观察结果增加了我们对哮喘生理学基础的理解,但由于在这个年龄组进行测试的实用性,这些发现并没有导致广泛使用学龄前儿童的肺功能测量作为哮喘的临床预测指标。

期刊介绍: Pediatric Allergy and Immunology is the world''s leading journal in pediatric allergy, publishing original contributions and comprehensive reviews related to the understanding and treatment of immune deficiency and allergic inflammatory and infectious diseases in children. Other areas of interest include: development of specific and accessory immunity; the immunological interaction during pregnancy and lactation between mother and child. As Pediatric Allergy and Immunology promotes communication between scientists engaged in basic research and clinicians working with children, we publish both clinical and experimental work.
