Quality of Life and Bronchial Hyper-Responsiveness in Subjects With Bronchiectasis: Validation of the Seattle Obstructive Lung Disease Questionnaire in Bronchiectasis.

Bronchiectasis can adversely affect quality of life. However, the tests examining quality of life in bronchiectasis are not sufficient. We examined the validity of a measure designed for COPD, the Seattle Obstructive Lung Disease Questionnaire (SOLQ), in bronchiectasis. In addition, we aimed to compare the quality of life of subjects with bronchiectasis and bronchial hyper-responsiveness with that of those without to identify the effective factors. We studied 78 subjects with clinically stable bronchiectasis and 41 healthy controls matched for age and sex. Subjects were assessed by the SOLQ. A detailed history, physical examination, the Medical Outcomes Study 36-Item Short Form questionnaire, the Hospital Anxiety and Depression Scale, and spirometric measurements were obtained. Cronbach α coefficients, which reflected internal consistency, were >0.70 for all SOLQ components except for treatment satisfaction. SOLQ component scores correlated with all of the component scores of the Medical Outcomes Study 36-Item Short Form questionnaire and the Hospital Anxiety and Depression Scale, confirming their concurrent validity. All SOLQ scores correlated positively with percent-of-predicted FEV1, whereas the physical function, treatment satisfaction, and emotional function correlated negatively with the exacerbation frequency in Pearson analysis. Emotional and physical functions were positively associated with percent-of-predicted FEV1 in linear regression analysis. Compared with subjects without bronchial hyper-responsiveness, those with bronchial hyper-responsiveness had lower FEV1/FVC and more exacerbations/y. Compared with bronchiectasis subjects without bronchial hyper-responsiveness, those with bronchial hyper-responsiveness had significantly lower SOLQ, physical function, and coping skills scores but not emotional function and treatment satisfaction. The SOLQ is a valid instrument for determining quality of life in subjects with bronchiectasis. Subjects with bronchiectasis and bronchial hyper-responsiveness had a poorer quality of life, lower baseline spirometric values, and more frequent exacerbations, suggesting more severe disease.

Factors Associated With Quality of Life in Subjects With Stable COPD.

The purpose of this study was to assess the impact of bronchiectasis, anxiety and depression, and parameters of disease severity on health-related quality of life (HRQOL) in subjects with COPD. Sixty-two subjects with stable COPD were selected for the study. The presence of bronchiectasis in all subjects with COPD was investigated by high-resolution computed tomography. Pulmonary function tests were performed. Dyspnea was assessed using the Modified Medical Research Council (MMRC) dyspnea scale. Psychological disorders were investigated using the Hospital Anxiety and Depression Scale (HADS), and the HRQOL was examined using the St George Respiratory Questionnaire (SGRQ). High-resolution computed tomography revealed that 44 of 62 (70.9%) subjects with COPD had bronchiectasis. There were no differences in pulmonary function tests, symptoms, activities, impact, SGRQ total scores, and HADS scores between COPD subjects with and without bronchiectasis. Pearson correlation analyses showed that there was no significant association between the presence of bronchiectasis, bronchial wall thickness, or severity of bronchial dilatation and all subscales of the SGRQ or HADS scores. Additionally, HADS scores showed significant positive association with all subscales of the SGRQ in all subjects. In linear regression analysis, a statistically significant relationship was found between the SGRQ total score and percent-of-predicted FEV1, percent-of-predicted diffusing capacity of the lung for carbon monoxide, MMRC score, and anxiety score, but the SGRQ total score was not associated with age, body mass index, total number of hospitalizations, PaO2 , or depression score. The presence of bronchiectasis in subjects with COPD does not impact HRQOL and psychological disorders. However, disease severity, dyspnea levels, and anxiety scores predict poor HRQOL.
