Bronchiectasis is a multidimensional disease and, therefore, its severity or prognosis cannot be adequately quantified by analysing one single variable. The objective of the present study was to develop a multidimensional score that classifies the severity of bronchiectasis according to its prognosis. This is an observational multicentre study including 819 patients diagnosed with non-cystic fibrosis bronchiectasis using high-resolution computed tomography. 397 subjects were selected at random to construct the score while the remaining 422 were used for its validation. The outcome was 5-year all-cause mortality after radiological diagnosis. A logistic regression analysis was used to select the variables included in the final score.The final seven-point score incorporated five dichotomised variables: forced expiratory volume in 1 s % predicted (F, cut-off 50%, maximum value 2 points); age (A, cut-off 70 years, maximum value 2 points); presence of chronic colonisation by Pseudomonas aeruginosa (C, dichotomic, maximum value 1 point); radiological extension (E, number of lobes affected, cut-off two lobes, maximum value 1 point); and dyspnoea (D, cut-off grade II on the Medical Research Council scale, maximum value 1 point) to construct the FACED score. The validation cohort confirmed the score's validity.We conclude that this easy-to-use multidimensional grading system proved capable of accurately classifying the severity of bronchiectasis according to its prognosis. @ERSpublications An easy-to-use multidimensional grading system accurately classifies bronchiectasis severity according to prognosis
Background: Information on the role of fungi in non-cystic fibrosis (CF) bronchiectasis is lacking. Objectives: Our aim was to determine the prevalence of and factors associated with the isolation and persistence of fungi from sputum in these patients. Methods: We performed a multicenter observational study comprising adult patients with non-CF bronchiectasis. Persistence of Aspergillus spp. and Candida albicans was defined as the presence of ≥2 positive sputum cultures taken at least 6 months apart within a period of 5 years. Results: A total of 252 patients (62.7% women with a mean ± SD age of 55.3 ± 16.7 years) were included in the study. All patients had at least 1 sputum sample cultured for fungi, with a mean ± SD of 7 ± 6 cultures per patient. Eighteen (8.7%) and 71 (34.5%) patients had persistent positive cultures for Aspergillus spp. and C. albicans, respectively. Patients with persistence of Aspergillus spp. and C. albicans were older and had more daily purulent sputum. In addition, patients with persistent C. albicans had worse postbronchodilator forced expiratory volume in the first second (FEV1), more frequent cystic bronchiectasis, and more hospital-treated exacerbations. They were also more frequently treated with long-term antibiotics. Multivariate analysis showed that daily purulent sputum (OR = 3.75, p = 0.045) and long-term antibiotics (OR = 2.37, p = 0.005) were independently associated with persistence of Aspergillus spp. and C. albicans, respectively. Conclusions: Isolation and persistence of Aspergillus spp. and C. albicans are frequent in patients with non-CF bronchiectasis. Daily purulent sputum and chronic antibiotic treatment were associated with persistence of Aspergillus spp. and C. albicans, respectively.
Objectives: The objective of this study was to analyse lung function decline over time in bronchiectasis, along with the factors associated with it. Methods: Spirometry was measured every year in this observational, prospective study in 849 patients from the Spanish Bronchiectasis Registry (RIBRON). The main outcome was the decline in the rate of forced expiratory volume during the first second (FEV1). To be included in this study, patients needed a baseline assessment and at least one subsequent assessment. FEV1 decline was analysed using a mixedeffects linear regression model adjusted for clinically significant variables. Results: We recruited 849 bronchiectasis patients with at least two annual lung function measurements (follow-up range 1e4 years). A total of 2262 lung function tests were performed (mean 2.66 per patient, range 2e5). Mean baseline FEV1 was 1.78 L (standard deviation (SD) 0.76; 71.3% predicted). Mean age was 69.1 (SD 15.4) years; 543 (64% women. The adjusted rates of FEV1 decline were e0.98% predicted/ year (95% confidence interval (CI) e2.41 to e0.69) and e31.6 (95% CI e44.4 to e18.8) mL. The annual FEV1 decline was faster in those patients with chronic bronchial infection by Pseudomonas aeruginosa (e1.37% (52.1 mL) vs e0.37% (e24.6 mL); p < 0.001), greater age, increased number of severe exacerbations in the previous year and higher baseline FEV1 value. Discussion: In patients with bronchiectasis, the annual rate of FEV1 decline was e31.6 mL/year and it was faster in older patients and those with chronic bronchial infection by P. aeruginosa, increased number of previous severe exacerbations and higher baseline FEV1 value.
Aims: To estimate the prevalence of malnutrition in chronic obstructive pulmonary disease (COPD) patients hospitalized for exacerbation and to evaluate its clinical and prognostic influence on the exacerbation. Subjects/Methods: The subjects were 78 consecutive patients with moderate-to-severe COPD who were admitted to hospital with a diagnosis of exacerbation. Nutritional status was assessed by means of body mass index (BMI), bioelectric impedance analysis and levels of plasmatic albumin. Previous spirometry, 6-min walk test, severity of the exacerbation, days of hospitalization and readmission in the following 3 months were also evaluated. Results: Malnutrition [BMI <20 or fat-free mass (FFM) index ≤16] occurred in 38% of patients, while in 40% the involuntary weight loss revealed a malnutrition risk and in 18% patients the plasmatic albumin levels were <3 g/dl. FFM was correlated with forced expiratory volume in 1 s, forced vital capacity and distance walked in 6 min. Number of days of hospitalization were related to FFM, muscle mass, BMI and albumin. The patients readmitted in the following 3 months had less FFM than the patients who were not readmitted. Conclusions: The high prevalence of malnutrition among hospitalized COPD patients is related to their lung function and exercise tolerance. Moreover, nutritional parameters during exacerbation are related to length of hospitalization and readmission.
