咳嗽能预测特发性肺纤维化的预后
2011/08/12
摘要
背景和目的:在特发性肺纤维化(IPF)患者中咳嗽症状的临床意义和预测价值尚未完全清楚。本研究旨在描述IPF患者中咳嗽的特征和预测价值。
方法:选取正在进行的纵向研究数据库中的IPF患者。前瞻性记录咳嗽和其他临床指标。Logistic回归用于寻找咳嗽的预测因子和疾病进展的预测因子。疾病进展定义为用力肺活量下降10%、一氧化碳弥散能力下降15%、肺移植或临床就诊后6个月内死亡。采用Cox比例危险模型分析咳嗽与生存期或肺移植的相关性。
结果:242名患者入选本研究。84%的患者主诉有咳嗽。多变量分析显示,咳嗽在既往吸烟者中出现的可能性较低(OR 0.07, 95%CI 0.01-0.55, p = 0.01),在劳力性脱饱和患者(OR 2.56, 95%CI 1.15-5.72, p = 0.02)和用力肺活量较低患者(OR 0.76, 95%CI 0.60-0.96, p = 0.02)中出现的可能性较高。咳嗽能预测疾病的进展(OR 4.97, 95%CI 1.25-19.80, P= 0.02),也能预测生存期和肺移植(HR 1.78, 95%CI 0.94-3.35, p = 0.08),但与疾病严重程度无关。
结论:在IPF患者中,咳嗽在从不吸烟者和疾病晚期患者中较常见。咳嗽是疾病进展的独立预测因子,能预测生存期或肺移植的可能性。

Abstract
BACKGROUND AND OBJECTIVE: The clinical associations and prognostic value of cough in idiopathic pulmonary fibrosis (IPF) have not been adequately described. The objective of this study was to describe the characteristics and prognostic value of cough in IPF.
METHODS: Subjects with IPF were identified from an ongoing longitudinal database. Cough and other clinical variables were recorded prospectively. Logistic regression was used to determine predictors of cough and predictors of disease progression, defined as 10% decline in forced vital capacity, 15% decline in diffusing capacity of carbon monoxide, lung transplantation, or death within 6 months of clinic visit. The relationship of cough with time to death or lung transplantation was analyzed using Cox proportional hazards analysis.
RESULTS: Two-hundred and forty-two subjects were included. Cough was reported in 84% of subjects. On multivariate analysis, cough was less likely in previous smokers (OR 0.07, 95%CI 0.01-0.55, p = 0.01), and more likely in subjects with exertional desaturation (OR 2.56, 95%CI 1.15-5.72, p = 0.02) and lower forced vital capacity (OR 0.76, 95%CI 0.60-0.96, p = 0.02). Cough predicted disease progression (OR 4.97, 95%CI 1.25-19.80, p = 0.02) independent of disease severity, and may predict time to death or lung transplantation (HR 1.78, 95%CI 0.94-3.35, p = 0.08).
CONCLUSIONS: Cough in IPF is more prevalent in never-smokers and patients with more advanced disease. Cough is an independent predictor of disease progression and may predict time to death or lung transplantation.
