围月经期哮喘(PMA)的特征及其与哮喘严重程度和哮喘控制的关系:来自严重哮喘研究项目的数据
2012/12/31
摘要
背景:虽然围月经期哮喘(PMA)与严重哮喘和难控制哮喘有关,但两者相关性的特征了解较少。
目的:研究与PMA有关的临床、人口统计学和炎症因素,评价PMA与哮喘严重程度和哮喘控制之间的关系。
方法:入选参与国家心脏、肺和血液研究所进行的严重哮喘研究项目的女性哮喘患者,对这些患者进行的筛查问卷调查显示存在PMA症状。研究基线状态下的人口统计学变量、临床问卷调查数据、免疫炎症标志物和生理学参数与PMA的关系。PMA组和非PMA组之间采用单变量分析。经哮喘严重程度校正后建立PMA预测模型。其他模型用于阐述PMA在哮喘控制中的作用。
结果:17%的女性(n=92)存在自我发现的PMA,而且与较大的体重指数、较低的用力肺活量预测值百分数(FVC%)和较高的胃食管反流疾病发生率有关。52%的PMA患者满足严重哮喘标准,该比例在非PMA组患者仅为30%。对哮喘严重程度进行控制后,多变量分析显示,阿司匹林过敏和较低的FVC%预测值与出现PMA有关。此外,对哮喘严重程度和混杂因素控制后,PMA病史仍然与更多的哮喘症状和紧急就诊有关。
结论:PMA常见于严重哮喘的女性患者,而且与哮喘控制较差有关。对多个因素校正后,阿司匹林敏感和较低的FVC%预测值与PMA有关,这表明前列腺素的变化可能与该型哮喘有关。

Abstract
BACKGROUND: Although perimenstrual asthma (PMA) has been associated with severe and difficult to control asthma, it remains poorly characterized and understood.
OBJECTIVES: To identify clinical, demographic and inflammatory factors associated with PMA and to assess the association of PMA with asthma severity and control.
METHODS: Female asthmatics, recruited to the National Heart, Lung and Blood Institute’s Severe Asthma Research Program who reported PMA symptoms on a screening questionnaire, were analyzed in relation to basic demographics, clinical questionnaire data, immuno-inflammatory markers and physiologic parameters. Univariate comparisons between PMA and non-PMA groups were performed. A severity-adjusted model predicting PMA was created. Additional models addressed the role of PMA in asthma control.
RESULTS: Self-identified PMA was reported in 17% of the women (n=92) and associated with higher body mass index, lower percent-predicted forced vital capacity (FVC%) and higher gastroesophageal reflux disease rates. Fifty-two percent of the PMA group met criteria for severe asthma, as compared to 30% of the non-PMA group. In multivariable analyses controlling for severity, aspirin sensitivity and lower FVC% predicted were associated with the presence of PMA. Further, after controlling for severity and confounders, a history of PMA remained associated with more asthma symptoms and urgent healthcare utilization.
CONCLUSION: PMA is common in severe female asthmatics and associates with poorly controlled disease. Aspirin sensitivity and lower FVC% predicted are associated with PMA after adjusting for multiple factors suggesting alterations in prostaglandins may contribute to this phenotype.
