年轻男性入伍者运动试验阳性和阻塞性肺活量检测结果与20年后持续性哮喘有关
2012/12/31
摘要
背景:哮喘常常出现于儿童期或成人早期,也是应征入伍者的一个常见疾病。鉴别持续性哮喘的长期预测因素有可能有助于改善哮喘治疗和更好的控制哮喘。
目的:本试验在40岁男性应征入伍者中研究哮喘严重程度的预测因素,这些入伍者的哮喘出现于青年期。
方法:1987年~1990年因哮喘于中央军事医院就诊的119名入伍者入选本研究,约20年后对其进行随访。基于病史记录评价服役期间的哮喘严重程度,20年后,采用GINA指南评价哮喘严重程度。基线状态下肺功能检测和过敏症检测结果作为当前持续性哮喘的预测因素。
结果:与基线状态相比,随访时哮喘严重程度较低:11.8%的入伍者存在恢复,42.0%的入伍者存在间歇性哮喘,10.9%的入伍者存在轻度持续性哮喘,而35.3%的入伍者存在中度/严重持续性哮喘(p < 0.001)。多变量回归分析显示,对于当前持续性哮喘,基线状态下,运动试验阳性的优势比(OR)为3.2(95% CI 1.0-9.8, p = 0.046),FEV1/FVC %预测值下降的OR为4.0(95% CI 1.7-9.3, p = 0.002),FEF %预测值下降50%的OR为2.8(95% CI 1.3-6.4, p = 0.012)。
结论:约有一半的男性在20年的随访期中出现持续性哮喘。运动测试阳性和阻塞性肺活量检测结果与持续性哮喘有关,可作为哮喘严重程度的长期预测因子。

Abstract
BACKGROUND:Asthma often begins in childhood or early adulthood and is a common disease among conscripts. The identification of long-term predictive factors for persistent asthma may lead to improved treatment opportunities and better disease control.
OBJECTIVE:Our aim was to study the prognostic factors of the severity of asthma among 40-year-old male conscripts whose asthma began in youth.
METHODS:We studied 119 conscripts who were referred to the Central Military Hospital during 1987-1990 due to asthma and who attended a follow-up visit approximately 20 years later. Asthma severity was evaluated during military service according to the medical records, and 20 years later during a follow-up visit using Global Initiative for Asthma guidelines. We used the results of lung function and allergy tests at baseline as predictors of current persistent asthma.
RESULTS: Compared with baseline, asthma was less severe at follow-up: 11.8% of subjects were in remission, 42.0% had intermittent asthma, 10.9% had mild persistent asthma, and 35.3% had moderate/severe persistent asthma (p < .001). In multivariate models, a positive exercise test at baseline yielded an odds ratio (OR) of 3.2 (95% CI 1.0-9.8, p = .046), a decreased FEV(1)/FVC % predicted an OR of 4.0 (95% CI 1.7-9.3, p = .002), and a decreased FEF(50%) % predicted an OR of 2.8 (95% CI 1.3-6.4, p = .012) for current persistent asthma.
CONCLUSIONS:About half of the men had persistent asthma at the 20-year follow-up. Positive exercise tests and obstructive spirometry results were related to the persistence of asthma and may be useful long-term prognostic factors for asthma severity.
