血清脂联素与男性哮喘的不良转归有关
2011/11/23
摘要
背景:鼠类研究显示,全身给予脂联素对哮喘具有治疗作用。本实验分别在男性和女性哮喘患者中,研究血清脂联素浓度与哮喘控制/严重程度转归的关系。
方法:对美国青年前瞻性冠状动脉风险形成研究中的10、15和20年观察数据进行横断面分析和纵向分析。确定哮喘的依据为患者自报的15年前的医生诊断。哮喘转归包括出现疾病活动、呼吸道症状数和哮喘用药数、FEV1绝对值的纵向下降。15年时的血清脂联素作为一个预测指标。
结果:对411例入选患者开展多变量分析,对体重指数和协变量进行调整后,血清脂联素升高与男性哮喘患者疾病活动频繁(包括频繁的哮喘用药)、呼吸道症状增多和哮喘用药增多相关,但这些相关性未见于女性(P<0.05)。
结论:血清脂联素浓度升高是男性哮喘临床转归较差的独立相关因素,而女性则无这种相关性。如果未来研究能证实该生物学效应,那么调整全身脂联素浓度有可能成为男性哮喘治疗的新途径。

Abstract
BACKGROUND: Murine studies suggest a beneficial effect of systemic adiponectin on asthma. Our objective was to determine the association between serum adiponectin concentrations and asthma control/severity outcomes in men and women separately.
METHODS: Cross-sectional and longitudinal analyses of data from years 10, 15, and 20 examinations of the prospective coronary artery risk development in young adults study in the United States were performed. Asthma was defined by self-reported provider diagnosis at or prior to year 15 examination. Outcomes included presence of active disease, number of respiratory symptoms, and number of asthma medications; as well as longitudinal decline in absolute FEV(1). Year 15 serum adiponectin concentration was the predictor variable.
RESULTS: In a multivariable analysis of 411 eligible subjects, after adjusting for body mass index and covariates, higher serum adiponectin concentrations were associated with more frequent active disease (including more frequent use of any asthma medication), and greater number of respiratory symptoms and asthma medications among men but not among women with asthma (p for interactions between sex and adiponectin for all analyses < 0.05).
CONCLUSIONS: Higher serum adiponectin concentrations may be independently associated with adverse clinical outcomes of asthma in men but not in women. If biological effect is confirmed in future studies, modification of systemic adiponectin concentrations may open up newer ways to treat asthma in men.
