无哮喘健康成人中的肥胖症、脂联素和呼出气一氧化氮
2011/05/12
背景:流行病学研究显示,肥胖与哮喘的进展、严重程度及其控制紧密相关。然而,肥胖对无哮喘个体气道炎症的影响尚不清楚。本试验旨在研究呼出气一氧化氮分数(FeNO)(嗜酸性气道炎症的标志物)是否与无哮喘的健康成人肥胖相关。
方法:在117名过去无哮喘诊断、当前无哮喘症状的成人中,检测FeNO 、血清脂肪来源激素和脂肪素水平。采用相关分析和单变量、多变量线性回归分析,研究FeNO与肥胖相关检测指标(体重指数、身体脂肪量、身体脂肪比例)间的关系。
结果:经年龄、性别、慢性鼻炎、过敏症和肺功能校正后,多变量线性回归模型显示,FeNO与体重指数、身体脂肪含量、身体脂肪比例无显著相关性。此外,FeNO与血清瘦素、脂联素、肿瘤坏死因子-α和白介素6无显著相关性。
结论:上述结果表明,无哮喘的健康成人,肥胖对嗜酸性粒细胞气道炎症无显著影响,脂肪组织来源的激素和全身炎症也对嗜酸性粒细胞气道炎症无影响。

Abstract
Background. Epidemiological studies have shown that obesity/adiposity is closely associated with asthma in terms of development, severity, and control of asthma. However, effects of obesity/adiposity on airway inflammation are not well known in subjects without asthma. We assessed whether fractional exhaled nitric oxide (FeNO), a marker of eosinophilic airway inflammation, was associated with obesity/adiposity in nonasthmatic healthy adults.
Methods. We measured FeNO and serum levels of adipose-derived hormones and adipokines in 117 adult subjects without a previous diagnosis of asthma or current asthmatic symptoms. Associations between FeNO and measures of obesity/adiposity [body mass index (BMI), body fat mass, and body fat percentages] were examined by correlation analyses and uni- and multivariate linear regression analyses.
Results. FeNO was not significantly associated with BMI, body fat mass, or body fat percentage by a multivariate linear regression model, adjusting for age, gender, chronic rhinitis, atopy, and lung function. No significant association of FeNO with serum levels of leptin, adiponectin, tumor necrosis factor (TNF)-α, or interleukin (IL)-6 was observed.
Conclusions. These findings suggest that in healthy subjects without asthma, obesity/adiposity has no significant effect on eosinophilic airway inflammation and that hormones and systemic inflammation derived from adipose tissue do not affect eosinophilic airway inflammation.
