Abstract

Purpose: Symptoms are important components in determining asthma control and in the adjustment of treatment levels. However, clinical relevance of cough in severe asthma is not well-understood. This study aimed to evaluate the severity and association of cough with patient-reported outcomes (PROs) in patients with severe asthma.

Methods: This study analyzed cross-sectional data from the Korean Severe Asthma Registry. The severity of coughing and wheezing symptoms was assessed using a Visual Analog Scale (VAS) ranging from 0 to 100 for each symptom. Additionally, PROs included the Asthma Control Test (ACT), the Severe Asthma Questionnaire (SAQ), and the EuroQoL 5-Dimension (EQ-5D) index. Multivariate linear regression analysis was employed to explore the relationship between cough severity and other PRO scores.

Results: A total of 498 patients with severe asthma (age: 57.9 ± 13.1 years, females: 60.2%) were analyzed. The cough VAS score was higher than the wheeze score (median 30, [interquartile range 10-50] vs. 20 [0-50]; P < 0.001). Additionally, 22.5% of patients ranked in a higher tertile for cough severity compared to wheezing, while 18.5% ranked higher for wheezing severity than cough. Significant correlations were observed between cough and wheeze VAS scores (r = 0.61, P < 0.05) and between each symptom's VAS score and the SAQ (cough: r = -0.41, P < 0.001; wheeze: r = -0.52, P < 0.001), ACT scores (cough: r = -0.50, P < 0.001; wheeze: r = -0.63, P < 0.001) and EQ-5D index (cough: r = -0.40, P < 0.001; wheeze: r = -0.45, P < 0.001). In univariate regression analysis, the cough VAS score had weaker descriptive power (R2) values than the wheeze VAS score in relation to the PRO measures. Nevertheless, cough severity remained significantly associated with ACT, SAQ scores and EQ-5D index in multivariate analyses adjusted for wheeze severity and other confounders.

Conclusion: Cough frequently presents as a severe symptom in patients with severe asthma and could have distinct impact on asthma control and quality of life.

严重哮喘患者咳嗽严重程度与哮喘控制和生活质量的关系
目的:症状是决定哮喘控制和调整治疗水平的重要因素。然而,人们对重症哮喘患者咳嗽的临床意义还不甚了解。本研究旨在评估重症哮喘患者咳嗽的严重程度以及咳嗽与患者报告结果(PROs)之间的关联:本研究分析了韩国重症哮喘登记处的横断面数据。咳嗽和喘息症状的严重程度采用视觉模拟量表(VAS)进行评估,每种症状的量表范围从 0 到 100。此外,PROs还包括哮喘控制测试(ACT)、严重哮喘问卷(SAQ)和欧洲生活质量五维度(EQ-5D)指数。研究人员采用多变量线性回归分析来探讨咳嗽严重程度与其他 PRO 评分之间的关系:共分析了 498 名重症哮喘患者(年龄:57.9 ± 13.1 岁,女性:60.2%)。咳嗽 VAS 评分高于喘息评分(中位数 30,[四分位数间距 10-50] vs. 20 [0-50];P 2)。尽管如此,在对喘息严重程度和其他混杂因素进行调整后的多变量分析中,咳嗽严重程度仍与ACT、SAQ评分和EQ-5D指数显著相关:结论:咳嗽是重症哮喘患者经常出现的严重症状,对哮喘控制和生活质量有明显影响。
